推荐答案

我想扩大HenrikS的回答。如果你仍然想使用复选框对于这一点，你可以在两个复选框设置onItemClickListener，需要取消选择其他的onItemClick（）方法。一个例子是这样的： -

I want to expand HenrikS' answer. If you still want to use checkboxes for this, you can set an onItemClickListener on both the checkboxes and need to unselect other in the onItemClick() Method. An example would be like this:-

CheckBox cb1,cb2;
//Considering you can initialize the above variables
cb1.setOnCheckedChangeListener(new OnCheckedChangeListener{
    onCheckedChanged (CompoundButton view, boolean isChecked){
        cb2.setChecked(false);
    }
});
cb2.setOnCheckedChangeListener(new OnCheckedChangeListener{
    onCheckedChanged (CompoundButton view, boolean isChecked){
        cb1.setChecked(false);
    }
});

由于这样的麻烦，你应该使用单选按钮。

Due to this hassle, you should use radio buttons.
