Creating a Vertical Seekbar in Android

Vertical SeekBar ( For Android Nougat and above)

SeekBar is an extension of ProgressBar which has an added feature of draggable thumb.

Creating a horizontal seekbar is simple. But creating a vertical seekbar, its really tough if you are new to android. But believe me its really simple, just you have to add an extra attribute "rotation" to seekbar when defining it in xml layout just like below.

<SeekBar
android:id="@+id/seekBar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:rotation="270"/>

or

<SeekBar
android:id="@+id/seekBar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:rotation="90"/>

But wait. If you want to make it compatible for every devices and every Android OS, then you have to add one more attribute to it. Along with "rotation" attribute you have to add "splitTrack" attribute for the seekbar to appear vertical in your layout if you want it to work on android Lollipop or above.

<SeekBar
android:id="@+id/seekBar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:rotation="270"
android:splitTrack="false"/>
