android - 无法使用 Google drive api android 从 google drive 查询文件 "shared with me"

Question

public class QueryFilesSharedWithMeActivity extends BaseDemoActivity {

private ListView mResultsListView;
private ResultsAdapter mResultsAdapter;

@Override
protected void onCreate(Bundle b) {
    super.onCreate(b);
    setContentView(R.layout.activity_listfiles);
    mResultsListView = (ListView) findViewById(R.id.listViewResults);
    mResultsAdapter = new ResultsAdapter(this);
    mResultsListView.setAdapter(mResultsAdapter);
}

/**
 * Clears the result buffer to avoid memory leaks as soon as the activity is no longer
 * visible by the user.
 */
@Override
protected void onStop() {
    super.onStop();
    mResultsAdapter.clear();
}

@Override
public void onConnected(Bundle connectionHint) {
    super.onConnected(connectionHint);
    Query query = new Query.Builder()
            .addFilter(Filters.sharedWithMe())
            .build();
    Drive.DriveApi.query(getGoogleApiClient(), query)
            .setResultCallback(metadataCallback);
    showMessage("Connecting ...");
}

final private ResultCallback<DriveApi.MetadataBufferResult> metadataCallback =
        new ResultCallback<DriveApi.MetadataBufferResult>() {
            @Override
            public void onResult(DriveApi.MetadataBufferResult result) {
                showMessage("onResult ...");
                if (!result.getStatus().isSuccess()) {
                    showMessage("Problem while retrieving results");
                    return;
                }
                mResultsAdapter.clear();
                mResultsAdapter.append(result.getMetadataBuffer());
                showMessage("Count = "+mResultsAdapter.getCount());
           }
        };
 }

我无法使用上述代码查询已与我共享的文件和文件夹。每当我尝试查询 sharedWithMe() 时，我都会得到 mResultAdapter 数组计数“0”。请帮我解决这个问题。

Android API 使用 Drive.File 范围，这意味着您的应用可以访问由您的应用创建或明确打开的文件。其他文件不会出现在搜索结果中。
