看起来我们可以在RadioButton中使用以下内容:
android:button="@drawable/myCustomStateBackground"
但是那个drawable只占据了无线电广播通常会去的地方。理想情况下,我希望我的整个按钮背景是有状态的。所以当推动时,我希望整个按钮看起来像是处于按下状态。要做到这一点,我希望我可以这样做:
android:button="null"
android:background="@drawable/myCustomStateBackground"
但是后台drawable不知道push状态,就像button属性一样。有办法吗?

为您的radiobutton提供自定义样式:
<style name="MyRadioButtonStyle" parent="@android:style/Widget.CompoundButton.RadioButton">
<item name="android:button">@drawable/custom_btn_radio</item>
</style>
<强> custom_btn_radio.xml 强>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_checked="true" android:state_window_focused="false"
android:drawable="@drawable/btn_radio_on" />
<item android:state_checked="false" android:state_window_focused="false"
android:drawable="@drawable/btn_radio_off" />
<item android:state_checked="true" android:state_pressed="true"
android:drawable="@drawable/btn_radio_on_pressed" />
<item android:state_checked="false" android:state_pressed="true"
android:drawable="@drawable/btn_radio_off_pressed" />
<item android:state_checked="true" android:state_focused="true"
android:drawable="@drawable/btn_radio_on_selected" />
<item android:state_checked="false" android:state_focused="true"
android:drawable="@drawable/btn_radio_off_selected" />
<item android:state_checked="false" android:drawable="@drawable/btn_radio_off" />
<item android:state_checked="true" android:drawable="@drawable/btn_radio_on" />
</selector>
将drawables替换为您自己的。

如果您想更改单选按钮的唯一图标,那么您只能将android:button="@drawable/ic_launcher"
添加到单选按钮,并且为了使点击敏感,那么您必须使用选择器
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/image_what_you_want_on_select_state" android:state_checked="true"/>
<item android:drawable="@drawable/image_what_you_want_on_un_select_state" android:state_checked="false"/>
</selector>
并设置为您的电台android:background="@drawable/name_of_selector"

以编程方式添加背景图片
minSdkVersion 16
RadioGroup rg = new RadioGroup(this);
RadioButton radioButton = new RadioButton(this);
radioButton.setBackground(R.drawable.account_background);
rg.addView(radioButton);
