Question

sendmessagedelayed定时器怎么用

Answer 1

设置标记为，发送一次后改变标志位，然后循环不进行，操作完了 还原 标志位 继续.
使用DELAY就不要使用线程：
private Handler myhandler = new Handler(){
@Override
public void handleMessage(Message msg) {
switch (msg.what) {
case 1:
progress += 5;
if (progress < 100){
Message msg = myhandler.obtainMessage();
msg.what = 1;
myhandler.sendMessageDelayed(msg, 2000);
}
pgbar.setProgress(progress);
break;
}
super.handleMessage(msg);
}
};
