Question

我有一个RadioGroup rg1，我想获得所选单选按钮的值。

我知道我可以使用以下方法获取所选单选按钮的id：

if(rg1.getCheckedRadioButtonId()!=-1)
int id= rg1.getCheckedRadioButtonId()

给了我id，但我想要那个按钮的值。

Answer 1

您需要获取该索引处的单选按钮，然后获取该按钮文本的值。请尝试以下代码。

if(rg1.getCheckedRadioButtonId()!=-1){
    int id= rg1.getCheckedRadioButtonId();
    View radioButton = rg1.findViewById(id);
    int radioId = radioGroup.indexOfChild(radioButton);
    RadioButton btn = (RadioButton) rg1.getChildAt(radioId);
    String selection = (String) btn.getText();
}

Answer 2

试试这个：

RadioGroup rg = (RadioGroup)findViewById(R.id.youradio);
String radiovalue = ((RadioButton)findViewById(rg.getCheckedRadioButtonId())).getText().toString();

Answer 3

RadioGroup rg = (RadioGroup)findViewById(R.id.youradio);
String radiovalue = (RadioButton)this.findViewById(rg.getCheckedRadioButtonId())).getText().toString();

Answer 4

一行代码

String buisnesstype = ((RadioButton) rdtranscompany.findViewById(rdtranscompany.getCheckedRadioButtonId())).getText().toString();

Answer 5

rb1=(RadioButton)findViewById(rg1.getCheckedRadioButtonId());

现在您可以使用rb1.getText()获取已检查的Radiobutton上的文字

Answer 6

我认为你应该试试这个

RadioGroup rg=(RadioGroup)findViewById(R.id.youradio);
String radiovalue=(RadioButton)this.findViewById(rg.getCheckedRadioButtonId())).getText().toString();

Answer 7

RadioGroup bhktype_RadioGr = (RadioGroup)findViewById(R.id.bhkypeRadioGroup);
int flatTypeId = bhktype_RadioGroup.getCheckedRadioButtonId();
String flat_type = ((RadioButton) findViewById(flatTypeId)).getText().toString();

Answer 8

简单回答一行

View v = yourView;  // as a button

String radiovalue = (RadioButton)v).getText().toString();
