停止处理程序执行

要停止执行 Handler，请使用在其中运行的 runnable 删除附加到它的回调：

Runnable my_runnable = new Runnable() {
    @Override
    public void run() {
        // your code here
    }
};

public Handler handler = new Handler(); // use 'new Handler(Looper.getMainLooper());' if you want this handler to control something in the UI
// to start the handler
public void start() {
    handler.postDelayed(my_runnable, 10000);
}

// to stop the handler
public void stop() {
    handler.removeCallbacks(my_runnable);
}

// to reset the handler
public void restart() {
    handler.removeCallbacks(my_runnable);
    handler.postDelayed(my_runnable, 10000);
}
