Android语音识别回调不工作

我正在尝试在我的应用程序中实现语音识别。它会很好地加载语音识别面板，识别你说的话，然后一旦完成，它就应该返回到调用onActivityResult方法的应用程序。不幸的是，它没有，只是返回到设备主屏幕。知道我做错了什么吗

static final int VOICE_RECOGNITION_REQUEST_CODE = 1234;

/**
 * Handler from the listening thread
 */
public Handler mhandle = new Handler() {
    @Override
    public void handleMessage(Message msg) {
        switch (msg.what) {
            case MAXOVER_MSG :
                Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
                intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
                startActivityForResult(intent, VOICE_RECOGNITION_REQUEST_CODE);
            break;
            default :
                super.handleMessage(msg);
            break;
        }
    }

};

/**
 * Handle the results from the recognition activity.
 */
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == VOICE_RECOGNITION_REQUEST_CODE && resultCode == RESULT_OK) {
        Log.i("hmm","This never seems to get called..");
    }

    super.onActivityResult(requestCode, resultCode, data);
}

由于某种原因，您的应用程序可能正在

finish

ing。您是否使用单_TOP或单_TASK或其他特殊函数标志来启动活动（无论是出于启动活动的目的还是在AndroidManifest.xml中）
