Android：填充Seek Bar的进度条高度与Thumb Size相同

Question

您已经在Android中开发了自定义搜索栏，我希望搜索栏的进度条与搜索栏拇指的高度相同。我怎么能实现它有没有人知道我们如何做到这一点。

  

red_progress.xml

<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >

<item
    android:id="@android:id/background"
    android:drawable="@drawable/slider_fill_default_patch"
    />
<item android:id="@android:id/secondaryProgress">
    <scale
        android:drawable="@drawable/slider_fill_patch"
        android:scaleWidth="100%"

        />
</item>
<item android:id="@android:id/progress">
    <scale
        android:drawable="@drawable/slider_fill_patch"
        android:scaleWidth="100%"/>
</item>

  

red_scrubber_control.xml

<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/alert_thumb_slider" android:state_enabled="false"/>
<item android:drawable="@drawable/alert_thumb_slider" android:state_pressed="true"/>
<item android:drawable="@drawable/alert_thumb_slider" android:state_selected="true"/>
<item android:drawable="@drawable/alert_thumb_slider"/>

<SeekBar
