Question

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.

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.

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

Thanks.

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

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();
            }
        }
    });
