prevent从一个小部件得到多次点击在短短 [英] Prevent a widget from getting clicked multiple times in a short span

问题描述

我有一个按钮，点击后，节省了画布图像文件，然后调用另一个活动。我遇到的问题是，经过测试，我发现，用户可以连续点击按钮两次活动调用之前，导致被写入两个文件。

I have a button that when clicked, saves a canvas to an image file and then calls another activity. The problem I am having is that through testing, I've noticed the user can click the button twice in a row before the activity is called, resulting in two files being written.

我还与另一个活动纺纱注意到了同样的问题。我在连续连续点击他们两次，最多弹出包含我所有的微调项目2列表视图。

I also noticed the same problem with spinners in another activity. I click them twice in a row in succession and up pops up 2 list views containing all my spinner items.

我一直在试图谷歌这一点没有多少运气。有没有一个简单的解决这个？

I've been trying to Google this without much luck. Is there a simple fix to this?

感谢。

推荐答案

那么事实证明，我不得不实施两项建议得到这个工作。 +1对你们每一个人。

Well as it turns out, I had to implement both suggestions to get this to work. +1 to each of you.

我用了一个不确定的进度对话框，和一个布尔值，像这样：

I used an indeterminate progress dialog, and a boolean value like so:

    Button send = (Button) findViewById(R.id.send);
    send.setOnClickListener(new OnClickListener() {         
        @Override
        public void onClick(View v) {
            if (mAllowSave) {
                mAllowSave = false;
                showDialog(SAVING_DIALOG);
                mSaveFileThread = new SaveFileThread(handler);
                mSaveFileThread.start();
            }
        }
    });
