如何使一个选项，褪色，但仍然可以点击在Android工作室？(How to make an opti

我现在有一个两个复选框，单击一个地方时，对方会自动取消选中。我想保持这种但是有一个选中成为一个褪色的白色，但仍可以点击，和可读性，如果用户决定改变他/她的想法。

这是当前的代码，我有：

 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)将使它看起来有所褪色。

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);
    }
});
