在Android中使用ArrayAdapter进行自定义筛选
我想过滤我的ListView，这是用这个ArrayAdapter填充：
package me.alxandr.android.mymir.adapters; import java.util.ArrayList; import java.util.Collection; import java.util.Collections; import java.util.HashMap; import java.util.Iterator; import java.util.Set; import me.alxandr.android.mymir.R; import me.alxandr.android.mymir.model.Manga; import android.content.Context; import android.util.Log; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.ArrayAdapter; import android.widget.Filter; import android.widget.SectionIndexer; import android.widget.TextView; public class MangaListAdapter extends ArrayAdapter<Manga> implements SectionIndexer { public ArrayList<Manga> items; public ArrayList<Manga> filtered; private Context context; private HashMap<String, Integer> alphaIndexer; private String[] sections = new String[0]; private Filter filter; private boolean enableSections; public MangaListAdapter(Context context, int textViewResourceId, ArrayList<Manga> items, boolean enableSections) { super(context, textViewResourceId, items); this.filtered = items; this.items = filtered; this.context = context; this.filter = new MangaNameFilter(); this.enableSections = enableSections; if(enableSections) { alphaIndexer = new HashMap<String, Integer>(); for(int i = items.size() - 1; i >= 0; i--) { Manga element = items.get(i); String firstChar = element.getName().substring(0, 1).toUpperCase(); if(firstChar.charAt(0) > 'Z' || firstChar.charAt(0) < 'A') firstChar = "@"; alphaIndexer.put(firstChar, i); } Set<String> keys = alphaIndexer.keySet(); Iterator<String> it = keys.iterator(); ArrayList<String> keyList = new ArrayList<String>(); while(it.hasNext()) keyList.add(it.next()); Collections.sort(keyList); sections = new String[keyList.size()]; keyList.toArray(sections); } } @Override public View getView(int position, View convertView, ViewGroup parent) { View v = convertView; if(v == null) { LayoutInflater vi = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); v = vi.inflate(R.layout.mangarow, null); } Manga o = items.get(position); if(o != null) { TextView tt = (TextView) v.findViewById(R.id.MangaRow_MangaName); TextView bt = (TextView) v.findViewById(R.id.MangaRow_MangaExtra); if(tt != null) tt.setText(o.getName()); if(bt != null) bt.setText(o.getLastUpdated() + " - " + o.getLatestChapter()); if(enableSections && getSectionForPosition(position) != getSectionForPosition(position + 1)) { TextView h = (TextView) v.findViewById(R.id.MangaRow_Header); h.setText(sections[getSectionForPosition(position)]); h.setVisibility(View.VISIBLE); } else { TextView h = (TextView) v.findViewById(R.id.MangaRow_Header); h.setVisibility(View.GONE); } } return v; } @Override public void notifyDataSetInvalidated() { if(enableSections) { for (int i = items.size() - 1; i >= 0; i--) { Manga element = items.get(i); String firstChar = element.getName().substring(0, 1).toUpperCase(); if(firstChar.charAt(0) > 'Z' || firstChar.charAt(0) < 'A') firstChar = "@"; alphaIndexer.put(firstChar, i); } Set<String> keys = alphaIndexer.keySet(); Iterator<String> it = keys.iterator(); ArrayList<String> keyList = new ArrayList<String>(); while (it.hasNext()) { keyList.add(it.next()); } Collections.sort(keyList); sections = new String[keyList.size()]; keyList.toArray(sections); super.notifyDataSetInvalidated(); } } public int getPositionForSection(int section) { if(!enableSections) return 0; String letter = sections[section]; return alphaIndexer.get(letter); } public int getSectionForPosition(int position) { if(!enableSections) return 0; int prevIndex = 0; for(int i = 0; i < sections.length; i++) { if(getPositionForSection(i) > position && prevIndex <= position) { prevIndex = i; break; } prevIndex = i; } return prevIndex; } public Object[] getSections() { return sections; } @Override public Filter getFilter() { if(filter == null) filter = new MangaNameFilter(); return filter; } private class MangaNameFilter extends Filter { @Override protected FilterResults performFiltering(CharSequence constraint) { // NOTE: this function is *always* called from a background thread, and // not the UI thread. constraint = constraint.toString().toLowerCase(); FilterResults result = new FilterResults(); if(constraint != null && constraint.toString().length() > 0) { ArrayList<Manga> filt = new ArrayList<Manga>(); ArrayList<Manga> lItems = new ArrayList<Manga>(); synchronized (items) { Collections.copy(lItems, items); } for(int i = 0, l = lItems.size(); i < l; i++) { Manga m = lItems.get(i); if(m.getName().toLowerCase().contains(constraint)) filt.add(m); } result.count = filt.size(); result.values = filt; } else { synchronized(items) { result.values = items; result.count = items.size(); } } return result; } @SuppressWarnings("unchecked") @Override protected void publishResults(CharSequence constraint, FilterResults results) { // NOTE: this function is *always* called from the UI thread. filtered = (ArrayList<Manga>)results.values; notifyDataSetChanged(); } } } 但是，当我在filter上调用filter（'test'）时，根本没有任何事情发生（或者后台线程运行，但是列表没有按照用户的要求过滤）。 我该如何解决这个问题？
这解决了我的问题。 我不确定这是最好的解决scheme，但它的工作原理。 我的项目的开源，所以随时使用任何代码，如果certificate有用:-)。

我不觉得有必要做以上的任何事情。 重写POJO的toString（）方法，如…
public String toString() { return this.getCallTitle() == null ? "" : this.getCallTitle().toLowerCase(); }
TextWatcher只是过滤和更简单的方法。
adapter.getFilter().filter(chars.toString().toLowerCase());
除非你有非常自定义的过滤，否则这个解决scheme的工作 希望这有利于他人。
我写了这个类，基本上是ArrayAdapter一个副本，只是稍微修改一下类似于Alxandr的解决scheme，但是更加优雅。
我所做的只是将嵌套类ArrayAdapter.ArrayFilter的filter逻辑拉到ArrayAdapter类中以暴露它（并允许用户覆盖它）。

这个解决scheme的好处是它在应用程序中很漂亮，只需重写从ArrayAdapter.ArrayFilter类到ArrayAdapter中的filterObject方法即可：
public class MyAdapter extends OGArrayAdapter<OGScene> { // Do the rest of your adapter @Override protected boolean filterObject(OGScene myObject, String constraint) { // If true, the object will be in the list, if false, it will be filtered. // Do your own filtering with myObject as you desire return myObject.fulfillsConstraint(constraint); } }
我发现过滤ArrayAdapter的最好方法是创build我自己的filter类：
private class MyFilter extends Filter
然后在该函数中创build新的对象数组以在filter之后显示（您可以在class ArrayAdapter的源代码中find好的实现）
@Override protected FilterResults performFiltering(CharSequence prefix)
现在的诀窍就是用这种方法
@Override protected void publishResults(CharSequence constraint, FilterResults results)
当你使用arrays适配器时，你不能这样做：
myAdapterData = results.values
从那时起，你将数据从超级数据中断开，你必须这样做以保持对超级原始数据数组的引用：
data.clear(); data.addAll((List<YourType>) results.values);
然后重写
用getFilter（）
在你的适配器中，例如：
@Override public Filter getFilter() { if (filter == null) { filter = new MyFilter(); } return filter; }
