Java 我想让小部件工作活动'；s法

嗨，我正在制作Android应用程序，我想为它制作一个小部件。应用程序的概念是，它从“Voicemain\u活动”中获取stt（语音到文本）字符串，并将字符串放入“AddActivity”中创建的字段。在“AddActivity”中，有一个按钮可调用“Voicemain\u活动”。我正试图启动“Voicemain_活动”。所以我制作了这样的小部件代码。 公共类MyAppWidget扩展了AppWidgetProvider{

static void updateAppWidget(Context context, AppWidgetManager appWidgetManager,
                            int appWidgetId) {
    //CharSequence widgetText = context.getString(R.string.appwidget_text);
    // Construct the RemoteViews object
    RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.my_app_widget);
    // views.setTextViewText(R.id.appwidget_text, widgetText);
    Intent intent=new Intent(context, AddActivity.class);
    PendingIntent pe=PendingIntent.getActivity(context, 0, intent, 0);
    views.setOnClickPendingIntent(R.id.imageButton_voice, pe);
    // Instruct the widget manager to update the widget
    appWidgetManager.updateAppWidget(appWidgetId, views);

}

@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {

    super.onUpdate(context,appWidgetManager,appWidgetIds);
    // There may be multiple widgets active, so update all of them
    for (int appWidgetId : appWidgetIds) {
        updateAppWidget(context, appWidgetManager, appWidgetId);
    }
}

@Override
public void onEnabled(Context context) {
    // Enter relevant functionality for when the first widget is created
}

@Override
public void onDisabled(Context context) {
    // Enter relevant functionality for when the last widget is disabled
}

}

使获取“Voicemain_活动”的“AddActivity”如下所示

@Override
public void onClick(View v) {
    int view = v.getId();

    if(view == R.id.Bacode){
        finish();
    }
    else if(view == R.id.Voice){
        startActivityForResult(new Intent(this, VoiceMain_Activity.class), MY_UI);
    }
}

但这段代码使小部件只显示“Voicemain_活动”屏幕，没有获取字符串，也没有将其置于“AddActivity”中。如何使其工作？

问题有点令人困惑……问题是AddActivity正在启动Vociemain_活动，但没有返回结果？但是提供的代码主要是显示小部件框架中的方法？VoiceMain_活动是否调用setResult，AddActivity是否实现onActivityResult？请出示代码。此外，这可能有助于：
