我如何触发一个widget按钮的东西吗？ [英] How do I trigger something from a widget button?

问题描述

不管我做什么，我不能通过点击一个部件一个按钮触发任何东西。下面是一些code我写的，谁能告诉我，为什么在单击控件按钮时，的onReceive 不叫？

此外，我想运行按钮点击功能...基础上，code下面做我有个好主意？

 公共类WidgetProvider扩展AppWidgetProvider {    @覆盖
    公共无效的onUpdate（上下文的背景下，AppWidgetManager appWidgetManager，INT [] appWidgetIds）{        意向意图=新意图（背景下，WidgetProvider.class）;
        的PendingIntent的PendingIntent = PendingIntent.getBroadcast（上下文，0，意图，0）;        RemoteViews意见=新的RemoteViews（context.getPackageName（），R.layout.widget）;
        views.setOnClickPendingIntent（R.id.toggleButton，的PendingIntent）;
        appWidgetManager.updateAppWidget（appWidgetIds [0]，意见）;    }    @覆盖
    公共无效的onReceive（上下文的背景下，意图意图）{
        //为什么我没有拿到这里与按钮点击？
        Log.e（，intent.getAction（）！）;
    }
}
 

解决方案

尝试先调用的onReceive的超级方法。

  @覆盖
公共无效的onReceive（上下文的背景下，意图意图）{
    super.onReceive（背景下，意图）;
    //为什么我没有拿到这里与按钮点击？
    Log.e（，intent.getAction（）！）;
}
 

工作只是对我很好！

No matter what I do I cannot trigger anything by clicking on a button on a widget. Here is some code I wrote, can anyone tell me why onReceive isn't called when the widget button is clicked?

Furthermore, I want to run a function on button click... based on the code below do I have the right idea?

public class WidgetProvider extends AppWidgetProvider {

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

        Intent intent = new Intent(context, WidgetProvider.class);
        PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, intent, 0);

        RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget);
        views.setOnClickPendingIntent(R.id.toggleButton, pendingIntent);
        appWidgetManager.updateAppWidget(appWidgetIds[0], views);

    }

    @Override
    public void onReceive(Context context, Intent intent) {
        // why don't i get here with the button click?
        Log.e("!", intent.getAction());
    }
}

解决方案

Try to call the super method of onReceive first.

 @Override
public void onReceive(Context context, Intent intent) {
    super.onReceive(context, intent);
    // why don't i get here with the button click?
    Log.e("!", intent.getAction());
}

Worked just fine for me!
