Question

我有一个RadioGroup，里面有6个单选按钮。如果用户单击第六个单选按钮，将启用EditText进行键入。否则，EditText将保持禁用状态。我在此网站上尝试了许多解决方案，但仍然出现一些错误。最常见的错误是EditText保持禁用，尽管我将其设置为在单击第6个单选按钮时启用。下面是XML的代码：

 <TableRow
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_gravity="center_horizontal"
            android:layout_marginLeft="25dp"
            android:layout_marginTop="20dp"
            android:layout_marginRight="25dp">

            <RadioGroup

这可能会帮助您：

// getting the groug
RadioGroup radioGroup = (RadioGroup) findViewById(R.id.yourRadioGroup);  

    radioGroup.setOnCheckedChangeListener(new OnCheckedChangeListener() 
    {
        @Override
        public void onCheckedChanged(RadioGroup group, int checkedId) {
            // checkedId is the RadioButton selected
if(checkedId==6) {
// if the id of the checkedId equels to the id of the 6 button than make the editText enable 

myEditText.setEnable(true)
} else {
// else (wich mean that other redio button been clicked) make it disable.
myEditText.setEnable(false)
}
        }
    });

，然后在xml中确定您的陈述状态（启用或禁用）

单击单选组Android Studio中的单选按钮后启用EditText
