AsyncTaskLoader类型不匹配：无法从MyAsyncLoader转换为Loader

Question

我创建了一个AsyncTaskLoader：

public class MyAsyncLoader extends AsyncTaskLoader<List<MyObject>> {

private MyDataSource myDb_source;   

public MyAsyncLoader(Context context) {
    super(context);
    myDb_source = new MyDataSource(context);
    myDb_source.open();
}

@Override
public List<MyObject> loadInBackground() {
    List<MyObject> my_records = myDb_source.getAllRecords();
    return myObject_records;
}

@Override
public void deliverResult(List<MyObject> data) {
    if(isStarted()){
    super.deliverResult(data);
    }
}

}

在我的活动课上，我有这样的内容：

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


        @Override
public Loader<List<MyObject>> onCreateLoader(int id, Bundle args) {
    MyAsyncLoader myAsyncLoader = new MyAsyncLoader(this);
    return myAsyncLoader;   // Here i get the ERROR: Type mismatch: cannot convert from MyAsyncLoader to Loader<List<MyObject>>
}

检查您导入的Android.support.v4.content.Loader，而不是其他东西。
