从活动启动BroadCastReceiver

Question

我想从BroadcastReceiver开始Activity。我怎么能这样做？

Answer 1

定义您的BroadcastReceiver：

private final BroadcastReceiver             receiver
    = new BroadcastReceiver() {

    @Override
    public void onReceive(Context context, Intent intent) {
        // Do something
    }
};

在onResume中注册您的接收器：

@Override
protected void onResume() {
    super.onResume();

    IntentFilter filter = new IntentFilter();
    filter.addAction("SOME_ACTION");
    registerReceiver(receiver, filter);
}

在onPause中取消注册接收器：

@Override
protected void onPause() {
    super.onPause();

    unregisterReceiver(receiver);
}
