这很奇怪。为什么我postDelay 1000ms,比如1000次,他们似乎同时运行所有?我希望它每100毫秒运行一次。一切都马上就出来了!
或者我是否需要配置一些内容以使其并发。我使用的是Android 4.0。
这是我的代码:
public void startAniHandler() {
Runnable runnable = new Runnable() {
@Override
public void run() {
Log.v("running", "REad image and display handler");
}
};
Handler handler = new Handler(new android.os.Handler.Callback() {
@Override
public boolean handleMessage(Message msg) {
Log.v("stopping", "handler");
return false;
}
});
for(int i=0;i<100;i++) {
handler.postDelayed(runnable, 1000);
}
}
我的输出是:

Luksprog所说的工作:
hat for循环将以当前时间为起点发布Runnable,以便所有人同时完成,近似。你可能想要这样的东西:handler.postDelayed(runnable,1000 + 1000 * i);
