Answer 2

只需在RadioGroup中使用单选按钮！这就是你想要的！

Answer 3

如果要在选择一个选项时禁用其他选项，请创建禁用/启用方法

protected void setGroupState(boolean state)
{
     //here put all options to have state changed in one go
}

然后在应该更改“组”

状态的选项的单击处理程序中

以适当的状态调用它。例如setGroupState（假）;

最好的问候

Answer 4

单击Checkbox时，您可以将其他复选框设为false，当前状态为

           if (((CheckBox) v).isChecked()) {
            currentchk.setChecked(true);
             otherchkbox.setChecked(false);
            }

Answer 5

试试这样：

private OnCheckedChangeListener listener = new OnCheckedChangeListener() {
public void onCheckedChanged(CompoundButton arg0, boolean isChecked) {
if(isChecked){
switch(arg0.getId())
  {
    case R.id.firstCheckBox:
         firstCheckBox.setChecked(true);
         secondCheckBox.setChecked(false);
         thirdCheckBox.setChecked(false);
         break;
    case R.id.secondCheckBox:
         firstCheckBox.setChecked(false);
         secondCheckBox.setChecked(true);
         thirdCheckBox.setChecked(false);
         break;
   case R.id.thirdCheckBox:
        firstCheckBox.setChecked(false);
        secondCheckBox.setChecked(false);
       thirdCheckBox.setChecked(true);
        break;
  }
}

}
};

Answer 6

Well, you can use the property of the checkBox which is setClickable
Following is a simple example code which let a checkbox be disabled:

CheckBox check_1;
check_1 = (CheckBoX)findViewById(R.id.(the id of your checkbox in xml));
check_1.setClickable(false);
//then this checkbox will be disabled.

Hope this will help you.

Answer 7

当您点击其他布局或按钮等时，您可以添加此行代码 - ＆gt;

Kotlin：

yourCheckbox.isChecked = !yourCheckbox.isChecked

Java： yourCheckbox.setChecked() = !yourCheckbox.isChecked()
希望这可以帮助你：）
