Question

我想修改默认选择器以对启用和禁用复选框使用相同的drawable。为此，我认为我需要覆盖选择器的复选框。我需要使用相同的设备特定drawables。（没有自定义drawables）。感谢。

以下是Checkbox的默认选择器

    <!-- Disabled states -->

    <item android:state_checked="true" android:state_window_focused="false"
          android:drawable="@drawable/btn_check_on_disable" />
    <item android:state_checked="false" android:state_window_focused="false"

    <item android:state_checked="true" android:state_focused="true"
          android:drawable="@drawable/btn_check_on_disable_focused" />
    <item android:state_checked="false" android:state_focused="true"
          android:drawable="@drawable/btn_check_off_disable_focused" />

    <item android:state_checked="false" android:drawable="@drawable/btn_check_off_disable" />
    <item android:state_checked="true" android:drawable="@drawable/btn_check_on_disable" />

</selector>

这被定义为btn_check.xml

中的sdk -> platforms -> API_VERSION -> data -> res -> drawable

默认情况下，哪个选择器设置为Checkbox
