Android 相当于 javascript 的 setTimeout 和 clearTimeout？

Question

setTimeout https://stackoverflow.com/a/18381353/433570 有一个答案

它没有提供我们是否可以像在 javascript 中那样取消计时器的信息。

android有没有可以取消的定时器？

Answer 1

根据 the documentation 处理程序

public final void removeCallbacks (Runnable r)

Added in API level 1

Remove any pending posts of Runnable r that are in the message queue.

示例代码:

Runnable runnable = new Runnable() {
    public void run() {
        Log.i("Tag", "Runnable running!");
    }
};

Handler handler = new android.os.Handler();
handler.postDelayed(runnable, 1000);

handler.removeCallbacks(runnable);
