你可以在这里查看图片

这个 sulotion 是我能做到这一点的唯一方法.希望这有帮助

This sulotion was the only way i could do this. Hope this help

这是我的搜索栏:

         <SeekBar
            android:id="@+id/simpleProgressBar"
            android:layout_width="fill_parent"
            android:layout_height="12dp"
            android:max="100"
            android:progress="0"
            android:background="@null"
            android:shape="oval"
            android:splitTrack="false"
            android:progressDrawable="@drawable/progress_background"
            android:secondaryProgress="0"
            android:thumbOffset="10dp"
            android:thumb="@drawable/oval_seekbar_thumb" />

这是(progress_background.xml):

this is (progress_background.xml) :

<item android:id="@android:id/background">
    <shape android:shape="rectangle">
        <corners android:radius="5dp" />

        <gradient
            android:angle="270"
            android:endColor="@color/grey_line"
            android:startColor="@color/grey_line" />
    </shape>
</item>
<item android:id="@android:id/secondaryProgress">
    <clip>
        <shape android:shape="oval">
            <corners android:radius="5dp" />
            <gradient
                android:angle="270"
                android:endColor="@color/blue"
                android:startColor="@color/blue" />
        </shape>
    </clip>
</item>
<item android:id="@android:id/progress">
    <clip>
        <shape android:shape="rectangle">
            <corners android:radius="90dp" />

            <gradient
                android:angle="90"
                android:endColor="@color/colorPrimaryDark"
                android:startColor="@color/colorPrimary" />
        </shape>
    </clip>
</item>

这是拇指(oval_seekbar_thumb.xml):

and this is the thumb (oval_seekbar_thumb.xml) :

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item>
        <shape android:shape="oval">
            <solid android:color="#ffffff" />
            <stroke android:color="@color/colorPrimaryDark" android:width="3dp"/>
            <size android:height="12dp" android:width="12dp"/>
        </shape>
    </item>
</selector>

拇指的高度应与搜索栏的高度相同才能正常显示.

The height of the thumb should be same as the height of the seekbar to look properly.
