单选按钮 - 如何使用自定义绘制？ [英] RadioButton - how to use a custom drawable?

问题描述

看起来我们可以使用一个单选按钮以下内容：

It looks like we can use the following in a RadioButton:

android:button="@drawable/myCustomStateBackground"

但绘制只占那个地方无线电绘制通常会去。理想我想我的整个按钮的背景是有状态的。所以，当推，我想整个按钮看起来像它停留在pressed状态。为了做到这一点，我希望我可以做这样的事情：

but that drawable only occupies the spot where the radio drawable would normally go. Ideally I want my entire button background to be stateful. So when pushed, I want the entire button to look like its stuck in the pressed state. To do that, I was hoping I could do something like:

android:button="null"
android:background="@drawable/myCustomStateBackground"

但那么背景抽拉不知道关于推状态，像按钮属性一样。有没有变通的办法？

but then the background drawable doesn't know about push state, like the button attribute does. Is there a way around it?

推荐答案

给你的单选按钮自定义样式：

Give your radiobutton a custom style:

<style name="MyRadioButtonStyle" parent="@android:style/Widget.CompoundButton.RadioButton">
    <item name="android:button">@drawable/custom_btn_radio</item>
</style>

custom_btn_radio.xml

<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>

替换可绘有你自己的。

Replace the drawables with your own.
