Android 如何在按下时更改自定义键盘颜色。。。!
嘿,我已经创建了一个游戏,所以我用edit tex创建了自定义键盘(numPad),我可以在编辑文本上写一次数字(第一个数字出现一次,直到我将其退格,然后我可以再写一次),所以我想更改键盘的颜色我尝试了一个代码,按下时它会将按键更改为蓝色,但我想保持蓝色,例如,我按下了数字(1234)键盘上的数字将颜色更改为蓝色,并一直保持这种状态,直到我将此数字退格为其原始颜色(未压缩的颜色) 看看我的代码和图片,你会明白的 MainActivty.javaAndroid 如何在按下时更改自定义键盘颜色。。。!,android,colors,background,keyboard,Android,Colors,Background,Keyboard,嘿,我已经创建了一个游戏,所以我用edit tex创建了自定义键盘(numPad),我可以在编辑文本上写一次数字(第一个数字出现一次,直到我将其退格,然后我可以再写一次),所以我想更改键盘的颜色我尝试了一个代码,按下时它会将按键更改为蓝色,但我想保持蓝色,例如,我按下了数字(1234)键盘上的数字将颜色更改为蓝色,并一直保持这种状态,直到我将此数字退格为其原始颜色(未压缩的颜色) 看看我的代码和图片,你会明白的 MainActivty.java private CustomKeybo
