Android -- BroadCastReceiver的简单使用
//首先新建一个继承自BroadcastReceiver的广播监听类 class StartActiviryReceiver extends BroadcastReceiver { public final static String intentKey = "startTestActivity"; @Override public void onReceive(Context context, Intent intent) { Intent t = new Intent(MyActivity.this, TestActivity.class); startActivity(t); } }
//注册 private StartActiviryReceiver startActiviryReceiver; @Override protected void onResume() { super.onResume(); //注册监听广播 startActiviryReceiver = new StartActiviryReceiver(); registerReceiver(startActiviryReceiver, new IntentFilter(startActiviryReceiver.intentKey)); }
在完成某件事之后,进行广播通知
Intent intent = new Intent(StartActiviryReceiver.intentKey); sendBroadcast(intent);
