Java 我在ActionBar中有一个SearchView。我需要过滤器，当搜索字符串

我有个问题。。输入文本时，我需要在searchview中进行筛选

屏幕截图：

ExampleAdapter.java

public class ExampleAdapter extends CursorAdapter {

private List<String> items;
private TextView text;

public ExampleAdapter(Context context, Cursor cursor, List<String> items) {

    super(context, cursor, false);

    this.items = items;

}

@Override
public void bindView(View view, Context context, Cursor cursor) {

    text.setText(items.get(cursor.getPosition()));

}

@Override
public View newView(Context context, Cursor cursor, ViewGroup parent) {

    LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

    View view = inflater.inflate(R.layout.item, parent, false);

    text = (TextView) view.findViewById(R.id.item1);

    return view;

}

public class MainActivity extends Activity implements SearchView.OnQueryTextListener {

private List<String> items = new ArrayList<String>();

private Menu menu;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    getWindow().requestFeature(Window.FEATURE_ACTION_BAR);

    setContentView(R.layout.activity_main);
    items.add("AAAAAAA");
    items.add("BBBBBBB");
    items.add("CCCCCCC");


}



@Override
@TargetApi(Build.VERSION_CODES.HONEYCOMB)
public boolean onCreateOptionsMenu(Menu menu) {

    getMenuInflater().inflate(R.menu.example, menu);

    this.menu = menu;

    if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {

        SearchManager manager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);

        SearchView search = (SearchView) menu.findItem(R.id.search).getActionView();

        search.setSearchableInfo(manager.getSearchableInfo(getComponentName()));

        search.setOnQueryTextListener(this); 
        search.setQueryHint("Ara..");



    }

    return true;

}

        Object[] temp = new Object[] { 0, "default" };

        MatrixCursor cursor = new MatrixCursor(columns);

        for(int i = 0; i < items.size(); i++) {

            temp[0] = i;
            temp[1] = items.get(i);

            cursor.addRow(temp);


        }

        // SearchView

        final SearchView search = (SearchView) menu.findItem(R.id.search).getActionView();

        search.setSearchableInfo(manager.getSearchableInfo(getComponentName()));

        search.setSuggestionsAdapter(new ExampleAdapter(this, cursor, items));



    }
}



@Override

      loadHistory(newText);
    return false;

请帮帮我。我对这个题目一窍不通。谢谢

检查这个。。谢谢，但这不是我的助手
