Question

Xamarin，android。我做了一个改变背景颜色的选择器：

<selector xmlns:android="http://schemas.android.com/apk/res/android">
  <item android:state_checked="false">
    <shape>
      <solid
          android:color="#aaaaac"/>

      <corners
          android:radius="6dp" />
      <padding
          android:left="5dp"
          android:top="5dp"
          android:right="5dp"
          android:bottom="5dp" />
    </shape>
    <drawable
      drawableLeft="@drawable/male"/>
  </item>
  <item android:state_checked="true">
    <shape>

      <solid
          android:color="#357fca" />

      <corners
          android:radius="6dp" />
      <padding
          android:left="5dp"
          android:top="5dp"
          android:right="5dp"
          android:bottom="5dp" />
    </shape>
    <drawable
          drawableLeft="@drawable/male_pushed"/>
  </item>
</selector>

除此之外，我还想更改drawableft和文本颜色，如下所示。如果 - android:state_checked="false" 然后
android:textColor="#000000"和android:drawableLeft="@drawable/male"

if - android:state_checked="true" 然后是android:textColor="#ffffff"和

android:drawableLeft="@drawable/male_pushed"

怎么做？

您无法使用单一选择器设置多个属性，如drawableLeft，textColor等。您应该为每个属性创建选择器。

创建

<强> drawable_left_selector.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_checked="false" android:drawable="@drawable/male"/>
    <item android:state_checked="true" android:drawable="@drawable/male_pushed"/>
</selector>

<强> text_color_selector.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_checked="false" android:color="#000000"/>
    <item android:state_checked="true" android:color="#ffffff"/>
</selector>

<强> toggle_selector.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_checked="false">
        <shape>
            <solid android:color="#aaaaac"/>
            <corners android:radius="6dp" />
            <padding
                android:left="5dp"
                android:top="5dp"
                android:right="5dp"
                android:bottom="5dp" />
       </shape>
    </item>
    <item android:state_checked="true">
        <shape>

            <solid android:color="#357fca" />
            <corners android:radius="6dp" />
            <padding
                android:left="5dp"
                android:top="5dp"
                android:right="5dp"
                android:bottom="5dp" />
        </shape>
    </item>
</selector>

设置ToggleButton

<ToggleButton
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@drawable/toggle_selector"
    android:drawableLeft="@drawable/drawable_left_selector"
    android:textColor="@drawable/text_color_selector" />

切换按钮字体颜色和drawableft选择器
