解决方案
如果你想获得的检查单选按钮的值（radioGroup中里面只有一个项目），当你点击一个按钮，你可以使用这样的：
RadioGroup中组=（RadioGroup中）findViewById（R.id.radio_group_id）;
Button按钮=（按钮）findViewById（R.id.button_id）;//如果你想在一个TextView打印电台的价值
TextView的标签=（的TextView）findViewById（R.id.text_view_id）;button.setOnClickListener（新View.OnClickListener（）{
@覆盖
公共无效的onClick（视图v）{ INT checkedId = group.getCheckedRadioButtonId（）; 单选按钮单选=（单选）findViewById（checkedId）;
label.setText（radio.getText（））; }
}）;
I am having a dynamic set of radiobuttons whose value drawn from string array. I want to get the values of all selected radiobuttons on click of some button. How to do that ? Any idea
Below is my working copy

解决方案
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:
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());
}
});
