Question

我有像redo, undo, choose, delete这样的一系列图像。我需要了解如何在用户点击redo时实施，并且会突出显示。当用户点击undo时，redo按钮将返回默认状态并突出显示撤消按钮。

我对redo按钮

有以下实现

<selector xmlns:android="http://schemas.android.com/apk/res/android">
  <item
      android:state_enabled="false"
      android:drawable="@drawable/redo_off" />
  <item
      android:state_pressed="true"
      android:state_enabled="true"
      android:drawable="@drawable/redo_on" />
  <item
      android:state_focused="true"
      android:state_enabled="true"
      android:drawable="@drawable/redo_on" />
  <item
      android:state_enabled="true"
      android:drawable="@drawable/redo_off" />
</selector>

Answer 1

您可能必须在各自的单击侦听器中设置所需的状态。不确定是否可以通过selector xml文件完成此操作。

Answer 2

这就是诀窍 make方法切换并传递int值，如下所示

private void toggleButton(int value){
switch(value){
case 1:
//set enabled background color of the redo button
//set disabled background color of the undo button
//set disabled background color of the choose button
//set disabled background color of the delete button
break;
case 2:
//set disabled background color of the redo button
//set enabled background color of the undo button
//set disabled background color of the choose button
//set disabled background color of the delete button
break;
case 3:
//set disabled background color of the redo button
//set disabled background color of the undo button
//set enabled background color of the choose button
//set disabled background color of the delete button
break;
case 4:
//set disabled background color of the redo button
//set disabled background color of the undo button
//set disabled background color of the choose button
//set enabled background color of the delete button
break;
}
}
