如何从不同的LinearLayouts分组RadioButton？

我想知道是否可以将每个单独的RadioButton分组在一个独特的RadioGroup保持相同的结构。 我的结构是这样的：

• LinearLayout_main
  • LinearLayout_1
    • RadioButton1
  • LinearLayout_2
    • RadioButton2
  • LinearLayout_3
    • RadioButton3

正如你所看到的，现在每个RadioButton都是不同的LinearLayout的子LinearLayout 。 我尝试使用下面的结构，但它不工作：

• radioGroup中
  • LinearLayout_main
    • LinearLayout_1
      • RadioButton1
    • LinearLayout_2
      • RadioButton2
    • LinearLayout_3
      • RadioButton3

Answer 1

Google / Android上的好人似乎认为当你使用RadioButton时，你不需要Android UI /布局系统的其他方面的灵活性。 简单来说：他们不希望你嵌套布局和单选button。 叹。

所以你必须解决这个问题。 这意味着你必须自己实现单选button。

这真的不是太难。 在你的onCreate（）中，用你自己的onClick（）设置你的RadioButtons，这样当它们被激活时，setChecked（true）和其他button相反。 例如：

 class FooActivity { RadioButton m_one, m_two, m_three; @Override protected void onCreate(Bundle savedInstanceState) { ... m_one = (RadioButton) findViewById(R.id.first_radio_button); m_two = (RadioButton) findViewById(R.id.second_radio_button); m_three = (RadioButton) findViewById(R.id.third_radio_button); m_one.setOnClickListener(new OnClickListener() { public void onClick(View v) { m_one.setChecked(true); m_two.setChecked(false); m_three.setChecked(false); } }); m_two.setOnClickListener(new OnClickListener() { public void onClick(View v) { m_one.setChecked(false); m_two.setChecked(true); m_three.setChecked(false); } }); m_three.setOnClickListener(new OnClickListener() { public void onClick(View v) { m_one.setChecked(false); m_two.setChecked(false); m_three.setChecked(true); } }); ... } // onCreate() } 

是的，我知道 – 老式的方式。 但它的作品。 祝你好运！

Answer 2

那么，我写了这个简单的类。

就像这样使用它：

 // add any number of RadioButton resource IDs here GRadioGroup gr = new GRadioGroup(this, R.id.radioButton1, R.id.radioButton2, R.id.radioButton3); 

要么

 GRadioGroup gr = new GRadioGroup(rb1, rb2, rb3); // where RadioButton rb1 = (RadioButton) findViewById(R.id.radioButton1); // etc. 

你可以在Activity的onCreate（）中调用它。 无论您点击哪个RadioButton ，其他人都将被取消选中。 另外，如果某些RadioButtons在某个RadioGroup ，或者没有，就RadioGroup 。

这是这个class级：

 package pl.infografnet.GClasses; import java.util.ArrayList; import java.util.List; import android.view.View; import android.view.View.OnClickListener; import android.view.ViewParent; import android.widget.RadioButton; import android.widget.RadioGroup; public class GRadioGroup { List<RadioButton> radios = new ArrayList<RadioButton>(); /** * Constructor, which allows you to pass number of RadioButton instances, * making a group. * * @param radios * One RadioButton or more. */ public GRadioGroup(RadioButton... radios) { super(); for (RadioButton rb : radios) { this.radios.add(rb); rb.setOnClickListener(onClick); } } /** * Constructor, which allows you to pass number of RadioButtons * represented by resource IDs, making a group. * * @param activity * Current View (or Activity) to which those RadioButtons * belong. * @param radiosIDs * One RadioButton or more. */ public GRadioGroup(View activity, int... radiosIDs) { super(); for (int radioButtonID : radiosIDs) { RadioButton rb = (RadioButton)activity.findViewById(radioButtonID); if (rb != null) { this.radios.add(rb); rb.setOnClickListener(onClick); } } } /** * This occurs everytime when one of RadioButtons is clicked, * and deselects all others in the group. */ OnClickListener onClick = new OnClickListener() { @Override public void onClick(View v) { // let's deselect all radios in group for (RadioButton rb : radios) { ViewParent p = rb.getParent(); if (p.getClass().equals(RadioGroup.class)) { // if RadioButton belongs to RadioGroup, // then deselect all radios in it RadioGroup rg = (RadioGroup) p; rg.clearCheck(); } else { // if RadioButton DOES NOT belong to RadioGroup, // just deselect it rb.setChecked(false); } } // now let's select currently clicked RadioButton if (v.getClass().equals(RadioButton.class)) { RadioButton rb = (RadioButton) v; rb.setChecked(true); } } }; } 

Answer 3

使用我创build的这个类。 它会在您的层次结构中find所有可检查的子项。

 import java.util.ArrayList; import android.content.Context; import android.util.AttributeSet; import android.view.View; import android.view.ViewGroup; import android.widget.Checkable; import android.widget.LinearLayout; public class MyRadioGroup extends LinearLayout { private ArrayList<View> mCheckables = new ArrayList<View>(); public MyRadioGroup(Context context) { super(context); } public MyRadioGroup(Context context, AttributeSet attrs) { this(context, attrs, 0); } public MyRadioGroup(Context context, AttributeSet attrs, int defStyle) { super(context, attrs, defStyle); } @Override public void addView(View child, int index, android.view.ViewGroup.LayoutParams params) { super.addView(child, index, params); parseChild(child); } public void parseChild(final View child) { if(child instanceof Checkable) { mCheckables.add(child); child.setOnClickListener(new OnClickListener() { public void onClick(View v) { for(int i = 0; i < mCheckables.size();i++) { Checkable view = (Checkable) mCheckables.get(i); if(view == v) { ((Checkable)view).setChecked(true); } else { ((Checkable)view).setChecked(false); } } } }); } else if(child instanceof ViewGroup) { parseChildren((ViewGroup)child); } } public void parseChildren(final ViewGroup child) { for (int i = 0; i < child.getChildCount();i++) { parseChild(child.getChildAt(i)); } } } 

Answer 4

我创build了这两个方法来解决这个问题。 所有你需要做的就是传递RadioButton所在的ViewGroup（可以是RadioGroup，LinearLayout，RelativeLayout等等），并且它专门设置了OnClick事件，也就是说，只要其中一个RadioButton是ViewGroup在任何嵌套级别）被选中，其他的被取消select。 它适用于任意多的嵌套布局，只要你喜欢。

 public class Utils { public static void setRadioExclusiveClick(ViewGroup parent) { final List<RadioButton> radios = getRadioButtons(parent); for (RadioButton radio: radios) { radio.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { RadioButton r = (RadioButton) v; r.setChecked(true); for (RadioButton r2:radios) { if (r2.getId() != r.getId()) { r2.setChecked(false); } } } }); } } private static List<RadioButton> getRadioButtons(ViewGroup parent) { List<RadioButton> radios = new ArrayList<RadioButton>(); for (int i=0;i < parent.getChildCount(); i++) { View v = parent.getChildAt(i); if (v instanceof RadioButton) { radios.add((RadioButton) v); } else if (v instanceof ViewGroup) { List<RadioButton> nestedRadios = getRadioButtons((ViewGroup) v); radios.addAll(nestedRadios); } } return radios; } } 

活动内部的用法如下所示：

 ViewGroup parent = findViewById(R.id.radios_parent); Utils.setRadioExclusiveClick(parent); 

Answer 5

你需要做两件事情：

1. 使用mListView.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
2. 使您的自定义行视图实现可检查。

所以我认为更好的解决scheme是在内部的LinearLayout中实现Checkable：（感谢daichan4649，从他的链接https://gist.github.com/daichan4649/5245378 ，我把所有的代码粘贴在下面）

CheckableLayout.java

 package daichan4649.test; import android.content.Context; import android.util.AttributeSet; import android.view.View; import android.widget.Checkable; import android.widget.LinearLayout; public class CheckableLayout extends LinearLayout implements Checkable { private static final int[] CHECKED_STATE_SET = { android.R.attr.state_checked }; public CheckableLayout(Context context) { super(context, null); } public CheckableLayout(Context context, AttributeSet attrs) { super(context, attrs, 0); } public CheckableLayout(Context context, AttributeSet attrs, int defStyle) { super(context, attrs, defStyle); } private boolean checked; @Override public boolean isChecked() { return checked; } @Override public void setChecked(boolean checked) { if (this.checked != checked) { this.checked = checked; refreshDrawableState(); for (int i = 0; i < getChildCount(); i++) { View child = getChildAt(i); if (child instanceof Checkable) { ((Checkable) child).setChecked(checked); } } } } @Override public void toggle() { setChecked(!checked); } @Override protected int[] onCreateDrawableState(int extraSpace) { final int[] drawableState = super.onCreateDrawableState(extraSpace + 1); if (isChecked()) { mergeDrawableStates(drawableState, CHECKED_STATE_SET); } return drawableState; } } 

inflater_list_column.xml

 <?xml version="1.0" encoding="utf-8"?> <daichan4649.test.CheckableLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/check_area" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_gravity="center_vertical"> <TextView android:id="@+id/text" android:layout_width="0dip" android:layout_height="wrap_content" android:layout_gravity="center_vertical" android:layout_weight="1" android:gravity="center_vertical" /> <RadioButton android:id="@+id/radio" android:layout_width="wrap_content" android:layout_height="wrap_content" android:clickable="false" android:focusable="false" android:focusableInTouchMode="false" /> </daichan4649.test.CheckableLayout> 

TestFragment.java

 @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View view = inflater.inflate(R.layout.fragment_test, container, false); // 表示データList<String> dataList = new ArrayList<String>(); // 初期選択位置int initSelectedPosition = 3; // リスト設定TestAdapter adapter = new TestAdapter(getActivity(), dataList); ListView listView = (ListView) view.findViewById(R.id.list); listView.setAdapter(adapter); listView.setChoiceMode(ListView.CHOICE_MODE_SINGLE); listView.setItemChecked(initSelectedPosition, true); listView.setOnItemClickListener(new OnItemClickListener() { @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { // 選択状態を要素(checkable)へ反映Checkable child = (Checkable) parent.getChildAt(position); child.toggle(); } }); return view; } private static class TestAdapter extends ArrayAdapter<String> { private LayoutInflater inflater; public TestAdapter(Context context, List<String> dataList) { super(context, 0, dataList); inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); } @Override public View getView(int position, View convertView, ViewGroup parent) { final ViewHolder holder; if (convertView == null) { convertView = inflater.inflate(R.layout.inflater_list_column, null); holder = new ViewHolder(); holder.text = (TextView) convertView.findViewById(R.id.text); convertView.setTag(holder); } else { holder = (ViewHolder) convertView.getTag(); } // bindData holder.text.setText(getItem(position)); return convertView; } } private static class ViewHolder { TextView text; } 

Answer 6

没有什么能阻止你实现这个布局结构（ RadioGroup实际上是LinearLayout一个子类），但你不应该这样做。 首先你创build一个4层深的结构（使用另一种布局结构，你可以优化这个结构），其次，如果你的RadioButtons不是RadioGroup直接子RadioGroup ， 那么组中select的唯一一个项目将不起作用。 这意味着，如果您从该布局中select一个Radiobutton ，然后select另一个RadioButton ，则最终将select两个RadioButtons而不是最后一个选定的RadioButtons 。

如果你在这个布局中解释你想要做什么，也许我可以推荐你一个替代scheme。

Answer 7

我写了我自己的无线电组类，允许包含嵌套的单选button。 一探究竟。 如果你发现错误，请告诉我。

 import android.content.Context; import android.util.AttributeSet; import android.view.View; import android.view.ViewGroup; import android.widget.CompoundButton; import android.widget.LinearLayout; /** * This class is used to create a multiple-exclusion scope for a set of compound * buttons.

Basically, this class extends functionality of * {@link android.widget.RadioGroup} because it doesn't require that compound * buttons are direct childs of the group. This means you can wrap compound * buttons with other views. <br> * <br> * * <b>IMPORTATNT! Follow these instruction when using this class:</b><br> * 1. Each direct child of this group must contain one compound button or be * compound button itself.<br> * 2.

Answer 8

此解决scheme尚未发布如此发布：

第0步：创build一个CompountButton previousCheckedCompoundButton; 作为全局variables。

第1步：创build单选button的OnCheckedChangedListener

 CompoundButton.OnCheckedChangeListener onRadioButtonCheckedListener = new CompoundButton.OnCheckedChangeListener() { @Override public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { if (!isChecked) return; if (previousCheckedCompoundButton != null) { previousCheckedCompoundButton.setChecked(false); previousCheckedCompoundButton = buttonView; } else { previousCheckedCompoundButton = buttonView; } } }; 

第3步：将侦听器添加到所有单选button：

 radioButton1.setOnCheckedChangeListener(onRadioButtonCheckedListener); radioButton2.setOnCheckedChangeListener(onRadioButtonCheckedListener); radioButton3.setOnCheckedChangeListener(onRadioButtonCheckedListener); radioButton4.setOnCheckedChangeListener(onRadioButtonCheckedListener); 

而已！！ 你完成了。

Answer 9

我的$ 0.02基于@infografnet和@lostdev（也感谢@Neromancer的复合buttonbuild议！）

 public class AdvRadioGroup { public interface OnButtonCheckedListener { void onButtonChecked(CompoundButton button); } private final List<CompoundButton> buttons; private final View.OnClickListener onClick = new View.OnClickListener() { @Override public void onClick(View v) { setChecked((CompoundButton) v); } }; private OnButtonCheckedListener listener; private CompoundButton lastChecked; public AdvRadioGroup(View view) { buttons = new ArrayList<>(); parseView(view); } private void parseView(final View view) { if(view instanceof CompoundButton) { buttons.add((CompoundButton) view); view.setOnClickListener(onClick); } else if(view instanceof ViewGroup) { final ViewGroup group = (ViewGroup) view; for (int i = 0; i < group.getChildCount();i++) { parseView(group.getChildAt(i)); } } } public List<CompoundButton> getButtons() { return buttons; } public CompoundButton getLastChecked() { return lastChecked; } public void setChecked(int index) { setChecked(buttons.get(index)); } public void setChecked(CompoundButton button) { if(button == lastChecked) return; for (CompoundButton btn : buttons) { btn.setChecked(false); } button.setChecked(true); lastChecked = button; if(listener != null) { listener.onButtonChecked(button); } } public void setOnButtonCheckedListener(OnButtonCheckedListener listener) { this.listener = listener; } } 

用法（包含监听器）：

 AdvRadioGroup group = new AdvRadioGroup(findViewById(R.id.YOUR_VIEW)); group.setOnButtonCheckedListener(new AdvRadioGroup.OnButtonCheckedListener() { @Override public void onButtonChecked(CompoundButton button) { // do fun stuff here! } }); 

奖金：你可以得到最后一个选中的button，整个button的列表，你可以通过索引来检查任何button！

Answer 10

虽然这可能是一个较老的话题，我想快速分享我写的简单的hacky代码。它不适合每个人，也可以做一些改进。

使用这个代码的情况？
这个代码适用于有原始问题或类似的布局的人，在我的情况如下。 这是我个人使用的Dialog。

• LinLayout_Main
  • LinLayout_Row1
    • ImageView的
    • 单选button
  • LinLayout_Row2
    • ImageView的
    • 单选button
  • LinLayout_Row3
    • ImageView的
    • 单选button

代码是做什么的？
这段代码将枚举“LinLayout_Main”的子对象，对于每个“LinearLayout”子对象，它将枚举该View对象的任何RadioButton。

简单地说，它将看起来父母“LinLayout_Main”，并find任何儿童LinearLayouts中的任何RadioButtons。

MyMethod_ShowDialog
将显示一个XML布局文件的对话框，同时也看它设置“setOnClickListener”它find每个RadioButton

MyMethod_ClickRadio
将以与“MyMethod_ShowDialog”相同的方式循环每个RadioButton，但不是设置“setOnClickListener”而是“setChecked（false）”来清除每个RadioButton，然后作为最后一步将“setChecked（false）”赋给被调用的RadioButton点击事件。

 public void MyMethod_ShowDialog(final double tmpLat, final double tmpLng) { final Dialog dialog = new Dialog(actMain); dialog.requestWindowFeature(Window.FEATURE_NO_TITLE); dialog.setContentView(R.layout.layout_dialogXML); final LinearLayout tmpLayMain = (LinearLayout)dialog.findViewById(R.id.LinLayout_Main); if (tmpLayMain!=null) { // Perform look for each child of main LinearLayout int iChildCount1 = tmpLayMain.getChildCount(); for (int iLoop1=0; iLoop1 < iChildCount1; iLoop1++){ View tmpChild1 = tmpLayMain.getChildAt(iLoop1); if (tmpChild1 instanceof LinearLayout) { // Perform look for each LinearLayout child of main LinearLayout int iChildCount2 = ((LinearLayout) tmpChild1).getChildCount(); for (int iLoop2=0; iLoop2 < iChildCount2; iLoop2++){ View tmpChild2 = ((LinearLayout) tmpChild1).getChildAt(iLoop2); if (tmpChild2 instanceof RadioButton) { ((RadioButton) tmpChild2).setOnClickListener(new RadioButton.OnClickListener() { public void onClick(View v) { MyMethod_ClickRadio(v, dialog); } }); } } } } Button dialogButton = (Button)dialog.findViewById(R.id.LinLayout_Save); dialogButton.setOnClickListener(new Button.OnClickListener() { public void onClick(View v) { dialog.dismiss(); } }); } dialog.show(); } public void MyMethod_ClickRadio(View vRadio, final Dialog dDialog) { final LinearLayout tmpLayMain = (LinearLayout)dDialog.findViewById(R.id.LinLayout_Main); if (tmpLayMain!=null) { int iChildCount1 = tmpLayMain.getChildCount(); for (int iLoop1=0; iLoop1 < iChildCount1; iLoop1++){ View tmpChild1 = tmpLayMain.getChildAt(iLoop1); if (tmpChild1 instanceof LinearLayout) { int iChildCount2 = ((LinearLayout) tmpChild1).getChildCount(); for (int iLoop2=0; iLoop2 < iChildCount2; iLoop2++){ View tmpChild2 = ((LinearLayout) tmpChild1).getChildAt(iLoop2); if (tmpChild2 instanceof RadioButton) { ((RadioButton) tmpChild2).setChecked(false); } } } } } ((RadioButton) vRadio).setChecked(true); } 

可能有错误，从项目中复制并重命名为Voids / XML / ID

您也可以运行相同types的循环来找出哪些项目被检查

Answer 11

我面临同样的问题，因为我想在两个不同的线路布局中放置4个不同的单选button，这些布局将是无线电组的孩子。 为了实现RadioGroup中的欲望行为，我重载了addView函数

这是解决scheme

 public class AgentRadioGroup extends RadioGroup { public AgentRadioGroup(Context context) { super(context); } public AgentRadioGroup(Context context, AttributeSet attrs) { super(context, attrs); } @Override public void onViewAdded(View child) { if( child instanceof ViewGroup) { ViewGroup viewGroup = (ViewGroup) child; for(int i=0; i<viewGroup.getChildCount(); i++) { View subChild = viewGroup.getChildAt(i); if( subChild instanceof ViewGroup ) { onViewAdded(subChild); } else { if (subChild instanceof RadioButton) { super.onViewAdded(subChild); } } } } if (child instanceof RadioButton) { super.onViewAdded(child); } } } 

Answer 12

修改版@Infografnet解决scheme。 这是样品和易于使用。

RadioGroupHelper group = new RadioGroupHelper(this,R.id.radioButton1,R.id.radioButton2); group.radioButtons.get(0).performClick(); //programmatically

只需复制和过去

 package com.qamar4p.farmer.ui.custom; import java.util.ArrayList; import java.util.List; import android.app.Activity; import android.view.View; import android.widget.CompoundButton; import android.widget.RadioButton; public class RadioGroupHelper { public List<CompoundButton> radioButtons = new ArrayList<>(); public RadioGroupHelper(RadioButton... radios) { super(); for (RadioButton rb : radios) { add(rb); } } public RadioGroupHelper(Activity activity, int... radiosIDs) { this(activity.findViewById(android.R.id.content),radiosIDs); } public RadioGroupHelper(View rootView, int... radiosIDs) { super(); for (int radioButtonID : radiosIDs) { add((RadioButton)rootView.findViewById(radioButtonID)); } } private void add(CompoundButton button){ this.radioButtons.add(button); button.setOnClickListener(onClickListener); } View.OnClickListener onClickListener = v -> { for (CompoundButton rb : radioButtons) { if(rb != v) rb.setChecked(false); } }; } 

Answer 13

试试这种方式在LinearLayout添加RadioGroup 。

 <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="vertical" > <RadioGroup android:id="@+id/radioGroup1" android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="horizontal" android:weightSum="1" > <RadioButton android:id="@+id/radio0" android:layout_width="wrap_content" android:layout_height="wrap_content" android:checked="true" android:text="RadioButton" /> <RadioButton android:id="@+id/radio1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="RadioButton" /> <RadioButton android:id="@+id/radio2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="RadioButton" /> </RadioGroup> </LinearLayout> <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="vertical" > <RadioGroup android:id="@+id/radioGroup2" android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="horizontal" android:weightSum="1" > <RadioButton android:id="@+id/radio3" android:layout_width="wrap_content" android:layout_height="wrap_content" android:checked="true" android:text="RadioButton" /> <RadioButton android:id="@+id/radio4" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="RadioButton" /> <RadioButton android:id="@+id/radio5" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="RadioButton" /> </RadioGroup> </LinearLayout> </LinearLayout>
