Android get value of the selected radio button

问题

I have a RadioGroup rg1 and I want to get the value of the selected radio button.

I know that I can get the id of the selected radio button by using:

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

that gives me the id , but I want the value of that button.

回答1:

You need to get the radio button at that index, then get the value of the text of that button. Try this code below.

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();
}

try this:

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

回答3:

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

One Line Code

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

回答5:

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

Now you can use rb1.getText() to get the text on the Radiobutton that is checked

回答6:

I think you should try this

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