推荐答案

您有您的适配器放置到一个单独的过滤器。在code看起来是这样的。

You have to place your adapter to a separate filter. The code looks something like this.

ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
                android.R.layout.simple_list_item_1, android.R.id.text1,
                stringlist);
listView.setAdapter(adapter);
listView.setTextFilterEnabled(true);
Filter filter = adapter.getFilter();

和文本查询收听时，如果你的code是这个样子

And when listening for the text query, if your code look something like this

@Override
public boolean onQueryTextChange(String newText) {
    if (TextUtils.isEmpty(newText)) {
        listView.clearTextFilter();
    } else {
        listView.setFilterText(newText.toString());
    }
    return true;
}

就改成这样

@Override
public boolean onQueryTextChange(String newText) {
   if (TextUtils.isEmpty(newText)) {
        filter.filter(null);
   } else {
        filter.filter(newText);
   }
   return true;
}
