通过点击小部件开始我的应用程序 [英] Start my application by clicking on widget

问题描述

我试图<一个href=\"http://stackoverflow.com/questions/9946469/how-do-i-run-an-activity-from-a-button-on-a-widget-in-android\">How我在Android的一个部件运行按钮活动？为了启动我的应用程序上点击图像按钮。当我取消注释code将其切换图像，但是当我尝试c将其无助于使用$ C $。我想，而不是拉开我的申请。

 公共类MyWidgetIntentReceiver扩展广播接收器{    私有静态诠释的clickCount = 0;    @覆盖
    公共无效的onReceive（上下文的背景下，意图意图）{
        如果（intent.getAction（）。等于（pl.looksok.intent.action.CHANGE_PICTURE））{
            updateWidgetPictureAndButtonListener（上下文）;
        }
    }    私人无效updateWidgetPictureAndButtonListener（上下文的背景下）{
        Log.i（PROJECTCARUSO，updateWidgetPictureAndButtonListener）;
        RemoteViews remoteViews =新的RemoteViews（context.getPackageName（），R.layout.widget）;
// remoteViews.setImageViewResource（R.id.widget_button，getImageToSet（））;
//
// //记得要经常刷新按钮单击听众！
// remoteViews.setOnClickPendingIntent（R.id.widget_button，MyWidgetProvider.buildButtonPendingIntent（上下文））;
//
// MyWidgetProvider.pushWidgetUpdate（context.getApplicationContext（），remoteViews）;        意图int​​entClick =新意图（背景下，FragmentChange.class）;

        remoteViews.setOnClickPendingIntent（R.id.widget_button，的PendingIntent）;
    }    私人诠释getImageToSet（）{
        的clickCount ++;
        返回的clickCount％2 == 0？ R.drawable.app_icon：R.drawable.energy;
    }
}
 

解决方案

下面就是我终于开始工作：

 公共类WidgetProvider扩展AppWidgetProvider {    公共静态字符串SWITCH_WIDGET_UPDATE =MainActivity.Switch;
    @覆盖
    公共无效的onUpdate（上下文的背景下，AppWidgetManager appWidgetManager，INT [] appWidgetIds）{        Log.i（PROJECTCARUSO，的onUpdate）;        RemoteViews remoteViews =新的RemoteViews（context.getPackageName（），R.layout.widget）;
        remoteViews.setOnClickPendingIntent（R.id.widget_button，buildButtonPendingIntent（上下文））;        意图int​​entClick =新意图（背景下，FragmentChange.class）;
        的PendingIntent的PendingIntent = PendingIntent.getActivity（上下文，0，intentClick，0）;
        remoteViews.setOnClickPendingIntent（R.id.widget_button，的PendingIntent）;        pushWidgetUpdate（背景下，remoteViews）;    }
    公共静态的PendingIntent buildButtonPendingIntent（上下文的背景下）{
        意向意图=新的Intent（）;
        intent.setAction（CHANGE_PICTURE）;
        返回PendingIntent.getBroadcast（背景下，0，意向，PendingIntent.FLAG_UPDATE_CURRENT）;
    }
    公共静态无效pushWidgetUpdate（上下文的背景下，RemoteViews remoteViews）{
        组件名进myWidget =新的组件名（背景下，WidgetProvider.class）;
        AppWidgetManager经理= AppWidgetManager.getInstance（背景）;
        manager.updateAppWidget（进myWidget，remoteViews）;    }    @覆盖
    公共无效的onReceive（上下文的背景下，意图意图）{
        // TODO自动生成方法存根
        super.onReceive（背景下，意图）;
    }
}
 

I'm trying How do I run an Activity from a button on a widget in Android? in order to launch my application on click on an image button. When i un-comment the code it switches the images but when i try to use this code it does nothing. I'd like to kick off my application instead.

public class MyWidgetIntentReceiver extends BroadcastReceiver {

    private static int clickCount = 0;

    @Override
    public void onReceive(Context context, Intent intent) {
        if(intent.getAction().equals("pl.looksok.intent.action.CHANGE_PICTURE")){
            updateWidgetPictureAndButtonListener(context);
        }
    }

    private void updateWidgetPictureAndButtonListener(Context context) {
        Log.i("PROJECTCARUSO", "updateWidgetPictureAndButtonListener");
        RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.widget);
//      remoteViews.setImageViewResource(R.id.widget_button, getImageToSet());
//
//      //REMEMBER TO ALWAYS REFRESH YOUR BUTTON CLICK LISTENERS!!!
//      remoteViews.setOnClickPendingIntent(R.id.widget_button, MyWidgetProvider.buildButtonPendingIntent(context));
//
//      MyWidgetProvider.pushWidgetUpdate(context.getApplicationContext(), remoteViews);

        Intent intentClick = new Intent(context, FragmentChange.class);
        PendingIntent pendingIntent = PendingIntent.getActivity (context, 0,
        intentClick, 0);
        remoteViews.setOnClickPendingIntent (R.id.widget_button, pendingIntent);
    }

    private int getImageToSet() {
        clickCount++;
        return clickCount % 2 == 0 ? R.drawable.app_icon : R.drawable.energy;
    }
}

解决方案

Here's what i finally got to work:

public class WidgetProvider extends AppWidgetProvider {

    public static String SWITCH_WIDGET_UPDATE = "MainActivity.Switch";


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

        Log.i("PROJECTCARUSO","onUpdate");

        RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.widget);
        remoteViews.setOnClickPendingIntent(R.id.widget_button, buildButtonPendingIntent(context));

        Intent intentClick = new Intent(context, FragmentChange.class);
        PendingIntent pendingIntent = PendingIntent.getActivity (context, 0, intentClick, 0);
        remoteViews.setOnClickPendingIntent (R.id.widget_button, pendingIntent);

        pushWidgetUpdate(context, remoteViews);

    }


    public static PendingIntent buildButtonPendingIntent(Context context) {
        Intent intent = new Intent();
        intent.setAction("CHANGE_PICTURE");
        return PendingIntent.getBroadcast(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
    }


    public static void pushWidgetUpdate(Context context, RemoteViews remoteViews) {
        ComponentName myWidget = new ComponentName(context, WidgetProvider.class);
        AppWidgetManager manager = AppWidgetManager.getInstance(context);
        manager.updateAppWidget(myWidget, remoteViews);     

    }

    @Override
    public void onReceive(Context context, Intent intent) {
        // TODO Auto-generated method stub
        super.onReceive(context, intent);
    }
}
