爪哇代码：
private void fnRadioTextSet(String strval) {
rbtnYes = (RadioButton)findViewById(R.id.rbtnYes);
rbtnNo = (RadioButton)findViewById(R.id.rbtnNo);
rbtnDontKnow = (RadioButton)findViewById(R.id.rbtnDontKnow);
RadioGroup rbtnGrp = (RadioGroup)findViewById(R.id.QueGroup1);
String[] strArrtext = strval.split(",");
for (int intcount = 0; intcount < strArrtext.length; intcount++) {
rbtnGrp.getChildAt(intcount).settext("test");
}
//int i = rbtnGrp.getChildCount();
//Toast.makeText(getApplication(), rbtnGrp.getChildCount(),
// Toast.LENGTH_LONG).show();
/*String[] strtext = strval.split(",");
if (strtext.length > 0) {
}*/
}

Don't need the loop
不需要循环
rbtnYes.settext("sdklfhjsdf");
rbtnNo.settext("test");
rbtnDontKnow.settext("test");
