获取按钮坐标和检测，如果手指是在他们 - 机器人 [英] Get button coordinates and detect if finger is over them - Android

问题描述

我在我的Andr​​oid应用程序活动的4个按钮。这是它的样子：

正如你所看到的，textViews在屏幕的底部显示x和y坐标。坐标是在参照的相对布局。 （请参见下面给出code）

现在，我想要做的就是的4个按钮的X和Y坐标，在运行时，然后计算出如果我的手指触摸按键，同时移动或没有。在简单的话，我想preSS按钮刷卡我的手指在他们，而不是提升和感人。我怎样才能实现呢？我想在我的钢琴应用程序中实现它。

我能得到在屏幕上的坐标，他们改变，因为我将我的手指。
所以，我的问题是我怎样才能获得按钮的坐标，并检测是否我的手指轻扫在他们之上：？

I have 4 buttons in my android app activity. This is what it looks like:

As you can see, the textViews at the bottom of the screen display the x and y coordinates. The coordinates are in reference to a relative layout. (See below given code)

Now, what I want to do is get the x and y coordinates of the 4 buttons at runtime and then figure out if my finger is touching the buttons while moving or not. In simple words, I want to press the buttons by swiping my finger over them instead of lifting and touching. How can I achieve it? I want to implement it in my piano application.

I was able to get the coordinates on screen and they change as I move my finger.
So, my question is How can I get the coordinates of the buttons and detect if my finger is swiping above them?:
