1、在 OnUpdate()中 定义一个 Intent
Intent startActivityIntent = new Intent(context,WidgetLife.class);
2、实例化一个 PendingIntent
PendingIntent Pintent = PendingIntent.getActivity(context,0,startActivityIntent,0);
3、实例RemoteView
RemoteViews ActivityView = new RemoteViews(context.getPackageName(),R.layout.widget_layout);
4、Button 事件
ActivityView.setOnClickPendingIntent(R.id.Button,Pintent);
