问题描述

i have one activity Main.java is open in my application, i want to close the activity using broadcast receiver , how to close the activity?

推荐答案

首先你需要Main.java被注册为接收器。你可以在Main.java的onResume注册它（）：

Firstly your Main.java needs to be registered as a receiver. You could register it in Main.java's onResume():

@Override
public void onResume() {
    registerReceiver(broadcastReceiver, new IntentFilter(BroadcasterClassName.NAME_OF_ACTION));
}

然后处理广播和完成您的活动：

Then handle the broadcast and finish your activity:

private BroadcastReceiver broadcastReceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        if (intent.getAction().equals(BroadcasterClassName.NAME_OF_ACTION)) {
            finish();
        }
    }
}
