如何使一个选项，褪色，但仍然可以点击在Android工作室？ [英] How to make an option fade but still be clickable on Android Studio?

问题描述

我现在有一个两个复选框，单击之一，当在哪里，对方会自动取消选中。我想保持这种但是有选中使人人成为褪色的白色，但仍然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code我有：

  chk1.setOnCheckedChangeListener（新CompoundButton.OnCheckedChangeListener（）{
        @覆盖
        公共无效onCheckedChanged（CompoundButton compoundButton，布尔B）{
            如果（CheckBox.isChecked（CHK1））{
            chk2.setChecked（假）;
            chk1.setChecked（二）;
            chk2.setAlpha（0.5F）;
        }
    }）;    chk2.setOnCheckedChangeListener（新CompoundButton.OnCheckedChangeListener（）{
        @覆盖
        公共无效onCheckedChanged（CompoundButton compoundButton，布尔B）{
            如果（CheckBox.isChecked（CHK2））{
            chk1.setChecked（假）;
            chk2.setChecked（二）;
            chk1.setAlpha（0.5F）;
        }
    }）;
 

解决方案

chk2.setAlpha（0.5F）将使其出现褪色。

  chk1.setOnCheckedChangeListener（新CompoundButton.OnCheckedChangeListener（）{
        @覆盖
        公共无效onCheckedChanged（CompoundButton compoundButton，布尔B）{
            chk2.setChecked（假）;
            chk1.setChecked（二）;
            chk2.setAlpha（0.5F）;
            chk1.setAlpha（1F）;
        }
    }）;chk2.setOnCheckedChangeListener（新CompoundButton.OnCheckedChangeListener（）{
    @覆盖
    公共无效onCheckedChanged（CompoundButton compoundButton，布尔B）{
        chk1.setChecked（假）;
        chk2.setChecked（二）;
        chk1.setAlpha（0.5F）;
        chk2.setAlpha（1F）;
    }
}）;
 

I currently have a two checkboxes, where when one is clicked, the other automatically unchecks. I would like to keep that however have the unchecked one become a faded white color, yet still be clickable and readable if the user decides to change his/her mind.

This is the current code I have:

 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);
        }
    });

解决方案

chk2.setAlpha(0.5f) would make it appear faded.

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);
    }
});
