RadioButton - 如何使用自定义drawable？

Question

看起来我们可以在RadioButton中使用以下内容:

android:button="@drawable/myCustomStateBackground"

但是那个抽屉只占据了无线电抽屉通常会去的地方.理想情况下,我希望我的整个按钮背景都是有状态的.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.有办法解决吗？

Answer 1

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>

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>

用自己的替换抽屉.

你应该设置android:button="@null"而不是"null".

你太近了!

完全解决方案:

<RadioGroup
    android:id="@+id/radioGroup1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" >

    <RadioButton
        android:id="@+id/radio0"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:button="@drawable/oragne_toggle_btn"
        android:checked="true"
        android:text="RadioButton" />

    <RadioButton
        android:id="@+id/radio1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:button="@drawable/oragne_toggle_btn"
        android:layout_marginTop="20dp"
        android:text="RadioButton" />

    <RadioButton
        android:id="@+id/radio2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:button="@drawable/oragne_toggle_btn"
        android:layout_marginTop="20dp"
        android:text="RadioButton" />
</RadioGroup>

选择器XML

<?xml version="1.0" encoding="utf-8"?>
 <selector xmlns:android="http://schemas.android.com/apk/res/android">

<item android:drawable="@drawable/orange_btn_selected" android:state_checked="true"/>
<item android:drawable="@drawable/orange_btn_unselected"    android:state_checked="false"/>

 </selector>

Answer 4

如果你想更改单选按钮的唯一图标,那么你只能添加android:button="@drawable/ic_launcher"到你的单选按钮,并为了使点击敏感,那么你必须使用选择器

 <?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>

并设置为您的收音机 android:background="@drawable/name_of_selector"
