If you want to get the values of the checked radioButton (inside the radioGroup it's only one item) when you click a button you could use this:
如果你想获得被检查的radioButton的值(在radioGroup中它只是一个项目),当你点击一个按钮时你可以使用它:
RadioGroup group = (RadioGroup)findViewById(R.id.radio_group_id);
Button button = (Button)findViewById(R.id.button_id);
//if you want to print radio's value in a textView
TextView label = (TextView)findViewById(R.id.text_view_id);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
int checkedId = group.getCheckedRadioButtonId();
RadioButton radio = (RadioButton)findViewById(checkedId);
label.setText(radio.getText());
}
});
