原标题:Android: SQLiteCursor/SimpleCursorAdapter in background

我的问题与安康有关。 我有以下法典(删除非相关部分):

public class MyActivity extends ListActivity {
    protected void onResume() {
        super.onResume();
        new UpdateTask().execute();
    }

    private class UpdateTask extends AsyncTask<Object, Object, ListAdapter> {
        protected ListAdapter doInBackground(Object... params) {
            SQLiteCursor cursor = db.getSomeData();
            startManagingCursor(cursor);
            SimpleCursorAdapter adapter = new SimpleCursorAdapter(this, ..., cursor, ..., ...);
            return adapter;
        }

        protected void onPostExecute(ListAdapter result) {
            listView.setAdapter(result);
        }
    }
 }

由此可见一线“Can t 创建手臂”,在光电蒸发线上没有叫Looper.prepare()”。

我理解为什么会发生这种情况,我不知道如何加以纠正(把这一点放在一个单独的线上)。 我已经发现:

But I don t really understand the reply. I have failed to google any example involving SQLiteCursor and AsyncQueryHandler.

您能否帮助? 感谢。

最佳回答

它希望立即发布<代码>。 简单的CursorAdapter必须在国库内实现。 您可以通过以下方式做到这一点:doInBackground(> 返回cursor,并在onPostExecute(上设置适应器。

See Painless Threading 如果你有点的话。

问题回答

只是将Looper.prepare()推倒了这种错误的方法的顶端。
