    RadioGroup:RadioButton必须放在RadioGroup的里面,这样才是单选。        选择器在RadioButton中的应用(drawableTop,textColor):    a)图片(不同装态显示不同的图片) <selector xmlns:android="http://schemas.android.com/apk/res/android" >     <item android:drawable="@drawable/ic_sms" android:state_checked="false"></item> <item android:drawable="@drawable/ic_sms_selected" android:state_checked="true"></item> </selector>    b)字体颜色(不同状态显示不同的字体颜色)       android:color="#ff669900"//颜色快捷(ctrl+?)搓不出来,需要自己打出来 <selector xmlns:android="http://schemas.android.com/apk/res/android" >     <item android:color="#ffffffff" android:state_checked="false"></item> <item android:color="#ff669900" android:state_checked="true"></item> </selector>        属性:          <RadioGroup> android:orientation="horizontal" <RadioButton> android:checked="true" android:button="@null" android:background="@drawable/start_btn_selector_01" </RadioButton>          </RadioGroup>        方法: radioGroup.addView(radioButton); ((RadioButton)radioGroup.getChildAt(int position)).setChecked(true); int position=radioGroup.indexOfChild(radioButton); int id=radioGroup.getCheckedRadioButtonId(); RadioButton radioButton=(RadioButton) radioGroup.findViewById(id); radioButton.getText();        监听器:          radioGroup.setOnCheckedChangeListener();
