如何更改视图时，另一种观点是pssed $ P $ /点击的 [英] How to change a view when another view is pressed/clicked

问题描述

如果我有按钮BTN1 和我有另一个按钮BTN2
如何在同一事件的两个视图连接像preSS，聚焦状态。

If i had Button btn1 and i had another Button btn2 how to connect the two views on the same events like onPress, onFocus.

让我解释一下：

当我preSS BTN1 现在 BTN1 是pressed和橙色背景的彩色
而上午pressing它，我想改变 BTN2 状态为pressed和背景颜色为橙色。

when i press btn1 now the btn1 is pressed and colored with orange background while am pressing it, i wanna change btn2 state to be pressed and with background color orange.

什么想法？

推荐答案

您可以设置为Button1触摸监听器，你可以叫 Button2.set pressed（真）后检查事件的作用。也就是说，如果你希望它是唯一pssed $ P $，而Button1的是pssed你会调用该函数时的行动是 ACTION_DOWN 并且当虚假的参数再次调用它$ P $行动是 ACTION_UP 。如果你想按钮2保持pressed可以使用onClicklistener而不是

You can set a touch listener for Button1 where you can call Button2.setPressed(true) after checking the action of the event . i.e if you want it to be pressed only while Button1 is pressed you would call the function when Action is ACTION_DOWN and call it again with a false parameter when the Action is ACTION_UP. If you want button2 to remain pressed you can use the onClicklistener instead
