android - 如何让一个选项淡出但仍然可以在 Android Studio 上点击？

Question

我目前有两个复选框，单击其中一个时，另一个会自动取消选中。我想保留它，但是未经检查的颜色变成褪色的白色，但如果用户决定改变主意，它仍然可以点击和阅读。

这是我目前的代码:

 chk1.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
            if (CheckBox.isChecked(chk1)) {
            chk2.setChecked(false);
            chk1.setChecked(b);
            chk2.setAlpha(0.5f);
        }
    });

    chk2.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
            if (CheckBox.isChecked(chk2)) {
            chk1.setChecked(false);
            chk2.setChecked(b);
            chk1.setAlpha(0.5f);
        }
    });

Answer 1

chk2.setAlpha(0.5f) 会使它显得褪色。

chk1.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
            chk2.setChecked(false);
            chk1.setChecked(b);
            chk2.setAlpha(0.5f);
            chk1.setAlpha(1f);
        }
    });

chk2.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
    @Override
    public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
        chk1.setChecked(false);
        chk2.setChecked(b);
        chk1.setAlpha(0.5f);
        chk2.setAlpha(1f);
    }
});
