回答1:

Maybe you could style a seekbar (instead of a progressbar) using your layerlist and add your image as the thumb scrubber?

<SeekBar
    android:id="@+id/seekBar1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:thumb="@drawable/your_android_image"
    android:progressDrawable="@drawable/your_layerlist_drawable"/>

回答2:

I think this moving image can be done using seekbar, this image is called thum drawable

You can try this tutorial it will help you a lot!!

set the seekbar attribute android:thumb="@drawable/seek_thumb" to point to the drawable that you desire
