Android锁屏应用按钮hover和序列
我正在开发一个Android锁屏应用程序。 但现在我被卡住了。 基本上我在屏幕上有一大堆按钮，当他们将手指从一个按钮拖到下一个按钮时，我需要能够注册，以及按顺序。
我怎样才能做到这一点？
我试图在OnTouch方法中使用MotionEvent.ACTION_MOVE，但它无法正常工作。 （它只适用于按钮1，因为我打印出logcat正在hover的按钮的ID，但它不会打印除按钮1之外的任何其他按钮）
请告诉我如何做到这一点？
我这样做了一次，你需要得到你所有的位置（x和y与yourButton.getLeft()和yourButton.getTop()但要小心，因为你可以得到布局创建后不要在onCreate()使用它然后在onTouch()方法中你有你的按钮的id，在onTouch()方法中你可以用me.getX() ， me.getY()得到手指的位置，但是这个值有第一个视图的亲戚，所以你必须有一些链接这个。
int rightXPos = yourButton.getLeft()+ me.getX() // yourButton is Button that int rightYPos = yourButton.getTop()+ me.getY() // Toached firstTime
使用log来捕获me.getX() ， me.getY()你理解你的自我。
然后用您的位置列表检查rightXPos和rightYPos ，然后您可以找到触摸的女巫按钮
我希望这对你有用
