android - RangeSlider 自定义设计 - Android

Question

我想自定义RangeSlider. 我已经有了一个设计SeekBar，现在我想将其转换为RangeSlider. 对于这么小的任务，我认为使用库是不合理的。

我想要达到的结果。查看 SeekBar 的图片

搜索栏 Xml XML

    <SeekBar
        android:id="@+id/seek_bar_frost_hard_temperature"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:progressDrawable="@drawable/custom_seekbar_frost_hard"
        android:layout_marginTop="@dimen/margin_padding_size_small"
        android:layout_marginBottom="@dimen/margin_padding_size_small"
        android:max="11"
        android:splitTrack="false"
        android:maxHeight="@dimen/seek_bar_height"
        android:paddingStart="@dimen/margin_padding_size_xsmall"
        android:paddingEnd="@dimen/margin_padding_size_xsmall"
        android:progress="0"
        android:thumb="@drawable/seekbar_frost_hard_thumb"/>
