我在标签式活动中的片段中有一个列表视图。我的列表视图有图片和文字。不幸的是，我不知道如何将搜索功能添加到片段中。搜索功能必须显示图片。我希望有人可以帮助我。如果有人不理解我的问题，请索取母马信息

答案 0 :(得分：0)
在XML中创建res/menu/menu.xml文件：
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
app:actionViewClass="android.support.v7.widget.SearchView"
android:id="@+id/search_menu"
android:title=""
android:icon="@mipmap/ic_search"
app:showAsAction="ifRoom|collapseActionView"/>
</menu>
然后将其添加到您的Fragment
的onCreate
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
}
onCreateOptionsMenu
@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
inflater.inflate(R.menu.menu, menu);
MenuItem item = menu.findItem(R.id.search_menu);
SearchView searchView = (SearchView) MenuItemCompat.getActionView(item);
searchView.setQueryHint("hit text");
searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
@Override
public boolean onQueryTextChange(String newText) {
//define your adapter as global
adapter.getFilter().filter(newText);
return true;
}
@Override
public boolean onQueryTextSubmit(String query) {
return false;
}
});
super.onCreateOptionsMenu(menu, inflater);
}
将String数组转换为ArrayList，然后让Adapter实现Filterable
class MyAdapter extends BaseAdapter implements Filterable{}
如果您不知道如何转换，请查看此example
最后根据您的需要覆盖适配器中的getFilter：
@Override
public Filter getFilter() {
Filter filter = new Filter() {
@Override
protected void publishResults(CharSequence constraint, FilterResults results) {
}
@Override
protected FilterResults performFiltering(CharSequence constraint) {
FilterResults results = new FilterResults();
// Implement your logic here
return results;
}
};
return filter;
}
