我想，让我的Andr​​oid应用程序的用户设置一些参数的能力。单选按钮是理想的这种情况。但是，我不喜欢按钮呈现收音机。

I am wanting to allow the user of my android application the ability to set some parameters. The radio button is ideal for this situation. However, I don't like the radio buttons are rendered.

是否有可能改变的单选按钮图标？例如，是否有可能创建一个自定义布局的每一行，并在布局中引用自己的图标，更改字体等。

Is it possible to change the radio button icon? For example, is it possible to create a custom layout for each row and in that layout reference my own icon and change the font et al.

推荐答案

有可能的话，你必须定义自己的风格单选按钮，在RES /价值/ styles.xml：

Yes that's possible you have to define your own style for radio buttons, at res/values/styles.xml:

<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="CustomTheme" parent="android:Theme">
   <item name="android:radioButtonStyle">@style/RadioButton</item>
</style>
<style name="RadioButton" parent="@android:style/Widget.CompoundButton.RadioButton">
   <item name="android:button">@drawable/radio</item>
</style>
</resources>

单选这里应该是一个有状态的绘制，radio.xml：

'radio' here should be a stateful drawable, radio.xml:

    <?xml version="1.0" encoding="utf-8"?>
    <selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_checked="true" android:state_window_focused="false"
        android:drawable="@drawable/radio_hover" />
    <item android:state_checked="false" android:state_window_focused="false"
        android:drawable="@drawable/radio_normal" />
    <item android:state_checked="true" android:state_pressed="true"
        android:drawable="@drawable/radio_active" />
    <item android:state_checked="false" android:state_pressed="true"
        android:drawable="@drawable/radio_active" />
    <item android:state_checked="true" android:state_focused="true"
        android:drawable="@drawable/radio_hover" />
    <item android:state_checked="false" android:state_focused="true"
        android:drawable="@drawable/radio_normal_off" />
    <item android:state_checked="false" android:drawable="@drawable/radio_normal" />
    <item android:state_checked="true" android:drawable="@drawable/radio_hover" />
    </selector>

然后，只需应用自定义主题，无论是整个应用程序或您所选择的活动。

Then just apply the Custom theme either to whole app or to activities of your choice.
