This to imagesViews has onClickListener, because I need to know which imageView was clicked. After when I click choosen picture I get result which picture was clicked.

我知道需要同样的结果，但我需要知道exacly我点击这个图像。我需要precise坐标被点击此ImageView的位置。我知道，在onTouch方法我有类似的功能，我需要。

I Know need the same result but I need to know where exacly I click on this image. I need precise coordinates where this imageView was clicked. I know that in onTouch method I have functions like I need.

推荐答案

有没有必要为你使用的onClick 事件，因为你可以用轻松捕捉点击在 onTouch 回调。点击是有一个 ACTION_DOWN 动作序列，几个 ACTION_MOVE 动作和一个 ACTION_UP 的行动。这些可以使用 event.getAction（）方法来获得。如果你得到一个 ACTION_DOWN 事件，然后一个 ACTION_UP 事件 - 这意味着用户只需点击您的查看。您还可以测量这些事件之间花费的时间，以确保它是一个简单的点击，不长个。而且，当然，你可以使用 event.getX（）和 event.getY（）方法来获取精确的触摸点。希望这有助于。

There is no need for you to use the onClick event, since you can easily capture the click using the onTouch callback. A click is a sequence of one ACTION_DOWN action, several ACTION_MOVE actions and one ACTION_UP action. These can be acquired using the event.getAction() method. If you get an ACTION_DOWN event and then an ACTION_UP event - it means that the user has just clicked your View. You can also measure time spent between these events to be sure that it was a simple click, not a long one. And, of course, you can use the event.getX() and event.getY() methods to get the exact touch point. Hope this helps.
