我遇到Handler问题。它在第一次实例化时工作正常。
处理程序位于View:
中 private long delayMillis;
private long mMoveDelay = 1000;
/**
* Create a simple handler that we can use to cause animation to happen. We
* set ourselves as a target and we can use the sleep()
* function to cause an update/invalidate to occur at a later date.
*/
private RefreshHandler mRedrawHandler;
class RefreshHandler extends Handler {
// serve per far vedere tile 2 almeno un tempo prestabilito checkTime
@Override
public void handleMessage(Message msg) {
delayMillis+=mMoveDelay;
System.out.println("--->handleMessage mMoveDelay"+10000);
System.out.println("--->handleMessage delayMillis"+delayMillis);
sleep();
}
public void sleep() {
//this.removeMessages(0);
sendMessageDelayed(obtainMessage(0), mMoveDelay);
System.out.println("--->sleep delayMillis"+delayMillis);
}
};
几次后我跑
mRedrawHandler = new RefreshHandler();
mRedrawHandler.sleep();
瞬间调用sendMessageDelayed。这篇文章中的问题似乎相似:
Handler.sendMessageDelayed(msg, delay) not working correctly
你有什么想法吗? 感谢
答案 0 :(得分:0)
在sleep方法中,acquireMessage(0)的对象是什么? 这似乎是问题所在。您不能使用上次使用的消息对象。你必须创建新的消息对象。
