安卓自定义广播接收者

1.定义广播的key

public static final  String BROADCAST_LOGIN_OUT= "login_account_out";

2.创建广播接收类对象

        // 初始化的时候注册广播接收类型
        private void registerReceiver() {
            IntentFilter filter = new IntentFilter();
            filter.addAction(AppCacheKey.BROADCAST_LOGIN_OUT);
            // 调用activity的方法注册广播接收者
            registerReceiver(myReceiver, filter);
        }
       // 退出之前调用activity的方法注销广播接收者
       unregisterReceiver(myReceiver);
    
        // 创建广播接收者
        private BroadcastReceiver myReceiver = new BroadcastReceiver() {
            @Override
            public void onReceive(Context context, Intent intent) {
                if (intent.getAction().equals(BROADCAST_LOGIN_OUT)) {
                    //通知
                    需要实现业务的代码
                }
            }
        };

3.调用activity的方法发送广播

sendBroadcast(new Intent(BROADCAST_LOGIN_OUT));
