的Andr​​oid preventing双点击一个按钮

我已经重新启用按钮的程序流程中，但也有一些情况下，我不能靠程序流程，并需要确保启用按钮。

I have been re-enabling buttons within the program flow, but there are some instances where, I cannot rely on program flow and need to ensure the button is enabled.

我设计了一个方法，使用重新启用这些按钮 countdowntimer 在我的code所示：

I have devised a way to re-enable these button using a countdowntimer and shown in my code:

button.setOnTouchListener(new View.OnTouchListener() {
        @Override public boolean onTouch(View v, MotionEvent event) {
            disableButton(button);
            countDwn();
            // Do something
            return false;
        }
    });

public void disableButton(Button button) {
    button.setEnabled(false);
}

public void enableButton(Button button) {
    button.setEnabled(true);
}

public void countDwn() {
    CountDownTimer countDownTimer = new CountDownTimer(2000, 1000) {
        public void onTick(long millisUntilFinished) {
        }

        public void onFinish() {
            enableButton(button);
        }
    }.start();
}

我就是关心，是，这可能是一个笨拙的或无效的方式来进行此事。我想咨询一下这一点，如果任何人有一个更优雅的建议？

What I am concerned about, is that this may be a clumsy or ineffective way to go about this. I am wanting advice about this and if anyone has a more elegant suggestion?

推荐答案

我不知道设置一个按钮启用=假是解决反复触摸问题的正确途径。

I am not sure setting a button to enable=false is the correct way to solve the "repeated touches" issue.

主要的原因是因为当一个按钮启用=假，大多数时间它都会有残疾人图形​​分配给它。因为我们只想要prevent意外反复触摸，而不是调用禁用的图形，我不知道这是正确的解决方案。

The main reason for that is since when a button is enable=false, most of the time it will have a Disabled graphics assigned to it. Since we only want to prevent accidental repeated touches, and not to invoke the disable graphics, I am not sure this is the correct solution.

prevent反复触摸

我会建议一个简单的解决方案，prevent的行动，如果从最后一个动作的时间小于 MINIMUM_ACTION_DELAY

I will suggest a simpler solution, prevent the action if the time from last action is less than MINIMUM_ACTION_DELAY.

。如果您不想点击动画，prevent的onTouch的动作。

If you want to get the click animation, prevent the action on the onClick listener. If you don't want the click animation, prevent the action on the onTouch.

例如，会的onClick是这样的：

For example, onClick will be something like this:

button.setOnClickListener(new View.OnClickListener() {

    private long mLastActionTime;

    @Override
    public void onClick(View v) {
        long currentTime = System.currentTimeMillis();
        if (currentTime - mLastActionTime < MINIMUM_ACTION_DELAY) {
            // Too soon, we don't want to handle this event
            return;
        }

        // Save the action time
        mLastActionTime = currentTime;

        // Execute action
        // TODO do something
    }
});
