Custom SeekBar which changes both Progress Color and Background Color while buffering
提问by beerBear
I want to build a custom SeekBar which has a secondary progress bar but by default is from end to end and shows progress for buffered data.
Think of it as the seekbar provided by most online video players e.g. youtube. So all in all we have the default seekbar, its default progress bar and a secondary progress bar which fills a color irrespective of the main progress/user's drag of the seekbar's notch and just dependent on buffered data.
我想构建一个自定义的 SeekBar，它有一个辅助进度条，但默认情况下是从头到尾显示缓冲数据的进度。
将其视为大多数在线视频播放器（例如 youtube）提供的搜索栏。所以总而言之，我们有默认的搜索栏、它的默认进度栏和一个辅助进度栏，它填充颜色而不管主要进度/用户对搜索栏槽口的拖动，并且只依赖于缓冲数据。
Till now I just have the normal seekbar and it changes color on user's drag/set progress.
Could someone please help with this?
到目前为止，我只有普通的搜索栏，它会根据用户的拖动/设置进度改变颜色。
有人可以帮忙吗？
My code so far:
seekbar_progress.xml

seekbar_progress.xml
<?xml version="1.0" encoding="utf-8"?>

Add another layer to your layer-list drawable with the id android:id/secondaryProgress
使用 id 将另一个图层添加到您的图层列表 drawable android:id/secondaryProgress

Here's your answer. Just add two lines in seekbar tag in xml
这是你的答案。只需在xml中的seekbar标签中添加两行
<SeekBar
android:progressTint="@color/black"
android:thumbTint="@color/black"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
change color accordingly.
相应地改变颜色。
