This message is already in use.的解决办法

This message is already in use.的解决方法

 

在开发项目的时候遇到报错This message is already in use.然后我看了下是和handler发送Message相关的,于是我就在网上找解决办法。其实意思就是说,这个消息已经在消息队列了,而且正被使用,而如果往同一个队列发送相同的西哦奥西对象就会报错。

这样,解决就很简单了,我们只需要判断这个消息是否在队列中有了,有了我们new一个一模一样的消息对象,然后发出去,这样就不会报错了。

 

下面贴出我之前的代码和修改后的代码:

 

报错的:

public void onMessage(Message msg) {
		handler.sendMessage(msg);
	}

 修改后的:


public void onMessage(Message msg) {
		if(handler.obtainMessage(msg.what, msg.obj) != null){
			Message _msg = new Message();
			_msg.what = msg.what;
			_msg.obj= msg.obj;
			msg = _msg;
//			return;
		}
		handler.sendMessage(msg);
	}

 

这样问题就解决了,当然效果怎么样我这里没测试,希望对大家有帮助。
