推荐答案

惊讶没有一个更简单的方法。如果你打算在此基础上按钮做一些特别的东西，虽然你也许应该检查ID而不是标签。

Surprised there isn't an easier way. If you are going to do something special though based on which button you should probably checked the ID instead of the Label.

radiogroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
         void onCheckedChanged(RadioGroup rg, int checkedId) {
              for(int i=0; i<rg.getChildCount(); i++) {
                   RadioButton btn = (RadioButton) rg.getChildAt(i);
                   if(btn.getId() == checkedId) {
                        String text = btn.getText();
                        // do something with text
                        return;
                   }
              }
         }
    });
