滑动手指在屏幕上的按钮激活，好像他们是pressed [英] Sliding finger across screen activating buttons as if they were pressed

问题描述

在我的情况下，标题是不够清楚，我会详细解释一下：

In case my title wasn't clear enough, I'll explain it in detail:

假设我们有充满了多个按钮（10+）的屏幕，我们preSS跪下一条，激活onTouch /的onClick。如果我们现在移动手指，没有提起，我想它来激活其他任何按钮，它滑过。在这种特殊情况下，我想，当你滑过一个虚拟的钢琴音色进行播放。

Say we have a screen filled with multiple buttons (10+), and we press down on one, activating onTouch/onClick. If we now move the finger, without lifting it, I want it to activate any other button it slides over. In this particular case, I want sound to be played when you slide over a virtual piano.

我知道你在哪里注册的每个ACTION_MOVE并找到了一些界限，激活新事件onTouchListener的解决方案，但是从优化远远如果你有多个按钮，并想让流畅无延迟滑动。

I know about the onTouchListener-solution where you register every ACTION_MOVE and find some boundaries that activates new events, but that's far from optimal if you have multiple buttons and want to allow smooth sliding without delay.

我也读<一个href=\"http://stackoverflow.com/questions/4838609/detect-which-view-your-finger-is-sliding-over-in-android\">this螺纹这表明，我们结合观的touchListener从活动gesturelistener，但再次，这并不在所有最适合我的处境感觉。

I also read this thread which suggested that we combine the touchListener of the View with a gesturelistener from the activity, but once again, this does not feel at all optimal for my situation.

我没有试过结合touchlistener与gesturelistener，但我会继续前进，这样做，如果有人告诉我，他们有这样做的没有其他办法。

I have not tried combining touchlistener with gesturelistener yet, but I will go ahead and do so if someone tells me they have no other way of doing this.

推荐答案

我居然把易的出路，并使用使用的按钮与onTouch法 ACTION_DOWN 和 ACTION_MOVE 与协调与 event.getX（）组合计算和 event.getY（） 让我来检测哪个按钮目前徘徊。它是免费的滞后与13个按钮。

I actually took the "easy" way out and used buttons with an onTouch-method using ACTION_DOWN and ACTION_MOVE with coordinate calculations that combined with event.getX() and event.getY() allows me to detect which button is currently hovered. It's lag free with 13 buttons.
