public class LikeReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        // 处理接收到的点赞通知
        // 更新UI、播放声音等
    }
}

public class MainActivity extends AppCompatActivity {
    private LikeReceiver likeReceiver;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // 注册广播接收器
        likeReceiver = new LikeReceiver();
        IntentFilter filter = new IntentFilter("com.example.ACTION_LIKE");
        registerReceiver(likeReceiver, filter);
    }

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

        // 取消注册广播接收器
        unregisterReceiver(likeReceiver);
    }
}

public class MainActivity extends AppCompatActivity {
    // ...

    @Override
    protected void onCreate(Bundle savedInstanceState) {

            @Override
            public void onClick(View v) {
                // 发送广播通知其他屏幕
                Intent intent = new Intent("com.example.ACTION_LIKE");
                sendBroadcast(intent);
            }
