SearchView在具有自定义适配器的ListView中
伙计们我需要一些help.I一直在试图在我的项目中实现一个SearchView，但我的项目包含一个自定义适配器连接到它的ListView ..我已经搜查了许多网站，但都有使用arrayadapter实现的例子。 。让我说我有一个员工类，它包含名称和年龄域..如何过滤员工使用他们的名字只..
public class MainActivity extends Activity implements SearchView.OnQueryTextListener { SearchView mSearchView; ListView mListView; //String mStrings[]= {"abc","def","efg","ghi","ijk","apple","agxhsdgc","abbbcc"}; ArrayList<Employee> emp_list=null; EmployeeAdapter emp_adapter=null; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); mSearchView=(SearchView) findViewById(R.id.searchView1); mListView=(ListView) findViewById(R.id.listView1); emp_list=new ArrayList<Employee>(); emp_list.add(new Employee("ABC", 24)); emp_list.add(new Employee("ACB", 24)); emp_list.add(new Employee("BVF", 28)); emp_list.add(new Employee("BRT", 28)); emp_list.add(new Employee("ANM", 23)); emp_adapter=new EmployeeAdapter(MainActivity.this, emp_list); mListView.setAdapter(emp_adapter); // mListView.setAdapter(new ArrayAdapter<String>(this, // android.R.layout.simple_list_item_1, // mStrings)); mListView.setTextFilterEnabled(true); setupSearchView(); } private void setupSearchView() { mSearchView.setIconifiedByDefault(false); mSearchView.setOnQueryTextListener(this); mSearchView.setSubmitButtonEnabled(true); mSearchView.setQueryHint("Search Here"); } @Override public boolean onQueryTextChange(String newText) { if (TextUtils.isEmpty(newText.toString())) { mListView.clearTextFilter(); } else { mListView.setFilterText(newText.toString()); } return true; } @Override public boolean onQueryTextSubmit(String query) { return false; } } 这是我扩展BaseAdapter的适配器类。
public class EmployeeAdapter extends BaseAdapter { Context ctx; ArrayList<Employee> emp_list; LayoutInflater linf=null; EmployeeHolder holder=null; public EmployeeAdapter(Context ctx, ArrayList<Employee> emp_list) { super(); this.ctx = ctx; this.emp_list = emp_list; linf=(LayoutInflater) ctx.getSystemService(Context.LAYOUT_INFLATER_SERVICE); } public class EmployeeHolder { TextView name; TextView age; } @Override public int getCount() { // TODO Auto-generated method stub return emp_list.size(); } @Override public Object getItem(int position) { // TODO Auto-generated method stub return emp_list.get(position); } @Override public long getItemId(int position) { // TODO Auto-generated method stub return position; } @Override public View getView(int position, View convertView, ViewGroup parent) { // TODO Auto-generated method stub if(convertView==null) { convertView=linf.inflate(R.layout.row, parent, false); holder=new EmployeeHolder(); holder.name=(TextView) convertView.findViewById(R.id.name); holder.age=(TextView) convertView.findViewById(R.id.age); convertView.setTag(holder); } else { holder=(EmployeeHolder) convertView.getTag(); } Employee e=(Employee) getItem(position); holder.name.setText(e.getName()); holder.age.setText(String.valueOf(e.getAge())); return convertView; } }
提前致谢..
试试这种方式，希望这会帮助你…
activity_main.xml中
<SearchView android:id="@+id/searchView1" android:layout_width="match_parent" android:layout_height="wrap_content"/> <ListView android:id="@+id/listView1" android:layout_width="match_parent" android:layout_height="0dp" android:layout_weight="1"/> </LinearLayout>
row.xml

Employee.java
public class Employee { private String name; private int age; public Employee(String name,int age){ this.name = name; this.age = age; } public String getName(){ return name; } public int getAge(){ return age; } }
好的答案在那里，但仍然有一些问题（错误的位置，当点击，serchview文本覆盖）如评论部分中所述，所以你也可以通过以下方式
参考更多信息： searchview listview android
我已经testing过了，到目前为止没有发现任何问题，如果有任何问题，请在评论部分提及。
模型类：MovieNames.java
public class MovieNames { private String movieName; public MovieNames(String movieName) { this.movieName = movieName; } public String getAnimalName() { return this.movieName; } }
2：listview_item.xml文件：
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:padding="10dp"> <TextView android:id="@+id/name" android:layout_width="wrap_content" android:layout_height="wrap_content" /> </RelativeLayout>

用于listview的ListViewAdapter.java类适配器：
import android.content.Context; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.BaseAdapter; import android.widget.TextView; import java.util.ArrayList; import java.util.Locale; public class ListViewAdapter extends BaseAdapter { // Declare Variables Context mContext; LayoutInflater inflater; private ArrayList<MovieNames> arraylist; public ListViewAdapter(Context context ) { mContext = context; inflater = LayoutInflater.from(mContext); this.arraylist = new ArrayList<MovieNames>(); this.arraylist.addAll(MainActivity.movieNamesArrayList); } public class ViewHolder { TextView name; } @Override public int getCount() { return MainActivity.movieNamesArrayList.size(); } @Override public MovieNames getItem(int position) { return MainActivity.movieNamesArrayList.get(position); } @Override public long getItemId(int position) { return position; } public View getView(final int position, View view, ViewGroup parent) { final ViewHolder holder; if (view == null) { holder = new ViewHolder(); view = inflater.inflate(R.layout.listview_item, null); // Locate the TextViews in listview_item.xml holder.name = (TextView) view.findViewById(R.id.name); view.setTag(holder); } else { holder = (ViewHolder) view.getTag(); } // Set the results into TextViews holder.name.setText(MainActivity.movieNamesArrayList.get(position).getAnimalName()); return view; } // Filter Class public void filter(String charText) { charText = charText.toLowerCase(Locale.getDefault()); MainActivity.movieNamesArrayList.clear(); if (charText.length() == 0) { MainActivity.movieNamesArrayList.addAll(arraylist); } else { for (MovieNames wp : arraylist) { if (wp.getAnimalName().toLowerCase(Locale.getDefault()).contains(charText)) { MainActivity.movieNamesArrayList.add(wp); } } } notifyDataSetChanged(); } } -
MainActivity.java类：
import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.view.View; import android.widget.AdapterView; import android.widget.ListView; import android.widget.SearchView; import android.widget.Toast; import java.util.ArrayList; public class MainActivity extends AppCompatActivity implements SearchView.OnQueryTextListener { // Declare Variables private ListView list; private ListViewAdapter adapter; private SearchView editsearch; private String[] moviewList; public static ArrayList<MovieNames> movieNamesArrayList = new ArrayList<MovieNames>(); @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); // Generate sample data moviewList = new String[]{"Xmen", "Titanic", "Captain America", "Iron man", "Rocky", "Transporter", "Lord of the rings", "The jungle book", "Tarzan","Cars","Shreck"}; // Locate the ListView in listview_main.xml list = (ListView) findViewById(R.id.listview); movieNamesArrayList = new ArrayList<>(); for (int i = 0; i < moviewList.length; i++) { MovieNames movieNames = new MovieNames(moviewList[i]); // Binds all strings into an array movieNamesArrayList.add(movieNames); } // Pass results to ListViewAdapter Class adapter = new ListViewAdapter(this); // Binds the Adapter to the ListView list.setAdapter(adapter); // Locate the EditText in listview_main.xml editsearch = (SearchView) findViewById(R.id.search); editsearch.setOnQueryTextListener(this); list.setOnItemClickListener(new AdapterView.OnItemClickListener() { @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { Toast.makeText(MainActivity.this, movieNamesArrayList.get(position).getAnimalName(), Toast.LENGTH_SHORT).show(); } }); } @Override public boolean onQueryTextSubmit(String query) { return false; } @Override public boolean onQueryTextChange(String newText) { String text = newText; adapter.filter(text); return false; } }
