BroadcastReceiver 启动 Activity 无法全屏

[smallprogrammer]

RT：
在广播里面启动一个Activity，该Activity无法全屏显示。正常启动该Activity是可以全屏的。求解答。。。
代码如下：

	/**
	 * 注册广播
	 */
	private void registerIntentReceivers() { 
		registerReceiver(new BroadcastReceiver() { 
			public void onReceive(Context context, Intent intent) {
				Intent intent1=new Intent(context, TrialControlActivity.class);
				intent1.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
				context.startActivity(intent1);
			}
		} , new IntentFilter(Intent.ACTION_SCREEN_OFF)); 
	}

调试日志里面警告信息如下：

IInputConnectionWrapper  showStatusIcon on inactive InputConnection
WindowManager  No window to dispatch pointer action 0

[AMinfo]

intent1.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
这段去掉后看看
