In short, create a Timer in onClick, showing the dialog box after the Timer reached its end. If onClick is called within the lifetime of the timer, cancel the timer and perform the operation you intend to be done for a double click. You can skip the Timer-thing if you show the meta-data some- where in your main-area. Then you just need to store System.currentTimeMillis() in a variable and check the difference the next time if it is within some threshold to decide if you have to show the preview-window or not.
