在Android Studio上选中复选框1时如何取消选中复选框，反之亦然？

Question

如何使复选框取消选中以前选中的复选框，反之亦然。我正在尝试开发一个应用程序，在其中检查您只能选择两个选项之一。我似乎无法让 onCheckedChangeListener 工作。我不想要单选按钮，因为它们不能被取消点击。

我尝试了 Noob 在类似问题下发布的这段代码。 I need to uncheck a checkbox when a particular checkbox is checked

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_setalarm);
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);

    final CheckBox chk1 = (CheckBox) findViewById(R.id.checkBox1);
    final CheckBox chk2 = (CheckBox) findViewById(R.id.checkBox2);

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

如果您确定不想使用 RadioButtons 并且只有两个可能的 CheckBox 选项，像这样简单的东西应该可以解决问题：

@Override
protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    setContentView(R.layout.layout_name);

    final CheckBox c1 = (CheckBox) findViewById(R.id.c1);
    final CheckBox c2 = (CheckBox) findViewById(R.id.c2);

    c1.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
            c2.setChecked(false);
            c1.setChecked(b);
        }
    });
    c2.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
            c1.setChecked(false);
            c2.setChecked(b);
        }
    });
}
