在Android API级别23上访问UserDictionary内容提供程序

问题描述

我正在开发一个android应用程序，旨在在屏幕上显示一个列表，其中包含用户词典中的内容.

I'm developing a android application which aims to show a list on the screen with the contents present in the user dictionary.

问题是，当我在Android API级别23内容提供程序中编译并运行应用程序时，会返回一个没有任何项目，没有任何数据的游标.

The problem is that when I compile and run the application in the Android API Level 23 Content Provider return a Cursor with no item, without any data.

这很奇怪，因为该应用程序的API之前的23(22、21、19等)会运行并正常在ListView中显示数据.

It's strange because the API's preceding 23 (22, 21, 19, ...) the app runs and displays the data in the ListView normally.

下面是我的活动代码:

import android.app.LoaderManager;
import android.content.CursorLoader;
import android.content.Loader;
import android.database.Cursor;
import android.provider.UserDictionary;
import android.os.Bundle;
import android.widget.ListView;
import android.widget.SimpleCursorAdapter;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity implements LoaderManager.LoaderCallbacks<Cursor> {

private ListView listView;
private SimpleCursorAdapter adapter;
private static final String[] COLUMNS = {
        UserDictionary.Words.WORD,
        UserDictionary.Words._ID,
        UserDictionary.Words.LOCALE
};

private static final int[] LIST_ITEM_VIEWS = {
        R.id.name,
        R.id.id_word,
        R.id.locale
};

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    listView = (ListView) findViewById(R.id.list);

    adapter = new SimpleCursorAdapter(getApplicationContext(), R.layout.item_list, null, COLUMNS, LIST_ITEM_VIEWS, 0);

    listView.setAdapter(adapter);

    getLoaderManager().initLoader(0, null, this);

}

@Override
public Loader<Cursor> onCreateLoader(int id, Bundle args) {
    return new CursorLoader(getApplicationContext(), UserDictionary.Words.CONTENT_URI, COLUMNS,
            null, null, UserDictionary.Words.WORD);
}

@Override
public void onLoadFinished(Loader<Cursor> loader, Cursor data) {
    adapter.swapCursor(data);

}

@Override
public void onLoaderReset(Loader<Cursor> loader) {
    adapter.swapCursor(null);
}
}
