如何使用getFilter的形式Listadapter [英] How to use getFilter form Listadapter

问题描述

我尝试在ListView中过滤适配器是ListAdapter，我找不到getFilter（），是否有任何工作？下面是我的代码。
$ b $ $ pre $ //将menuItems添加到ListView
final ListAdapter adapter = new SimpleAdapter（this，songsListData，
R.layout.playlist_item，new String [] {songTitle}，new int [] {
R.id.songTitle}）;

setListAdapter（adapter）;

sv.setOnQueryTextListener（new SearchView.OnQueryTextListener（）{
@Override
public boolean onQueryTextSubmit（String query）{
return false;
}

@Override
public boolean onQueryTextChange（String newText）{
//adapter.getFilter
return false;
}
}）;


解决方案

我发现自己很简单。

$ b $ pre $ final SimpleAdapter adapter = new SimpleAdapter（this，songsListData，
R.layout.playlist_item，new String [] {songTitle} ，new int [] {
R.id.songTitle}）;

sv.setOnQueryTextListener（new SearchView.OnQueryTextListener（）{
@Override
public boolean onQueryTextSubmit（String query）{
return false;
}

@Override
public boolean onQueryTextChange（String newText）{
adapter.getFilter（）。filter（newText）;
return false;
}
}）;


I try to filter in Listview where the adapter is ListAdapter, I couldn't find getFilter() , Is there any work around? Below is my code.

// Adding menuItems to ListView
            final ListAdapter adapter = new SimpleAdapter(this, songsListData,
                    R.layout.playlist_item, new String[]{"songTitle"}, new int[]{
                    R.id.songTitle});

            setListAdapter(adapter);

            sv.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
                @Override
                public boolean onQueryTextSubmit(String query) {
                    return false;
                }

                @Override
                public boolean onQueryTextChange(String newText) {
                    //adapter.getFilter
                    return false;
                }
            });

解决方案

I find myself, It's simple.

final SimpleAdapter adapter = new SimpleAdapter(this, songsListData,
                    R.layout.playlist_item, new String[]{"songTitle"}, new int[]{
                    R.id.songTitle});

    sv.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
                @Override
                public boolean onQueryTextSubmit(String query) {
                    return false;
                }

                @Override
                public boolean onQueryTextChange(String newText) {
                    adapter.getFilter().filter(newText);
                    return false;
                }
            });
