IllegalArgumentException, pointerIndex out of range when touching two vertical seekbars simultaneously multiple times

[iAlexM]

If I have two vertical seekbars and I touch them simultaneously multiple times the app crashes: (fairly easy to replicate
the implementation is described below:
Here is the implementation:

<com.h6ah4i.android.widget.verticalseekbar.VerticalSeekBarWrapper
            android:layout_width="wrap_content"
            android:layout_height="match_parent"
            android:layout_centerHorizontal="true"
            android:layout_below="@+id/left">

            <com.h6ah4i.android.widget.verticalseekbar.VerticalSeekBar
                android:id="@+id/vsb_volume_left"
                android:layout_width="0dp"
                android:layout_height="0dp"
                android:thumb="@drawable/drag_thumb_left"
                android:progressDrawable="@drawable/seekbar_progressbar"
                android:progress="50"
                android:maxHeight="9dp"
                android:minHeight="9dp"
                app:seekBarRotation="CW270"          
</com.h6ah4i.android.widget.verticalseekbar.VerticalSeekBarWrapper>
``
    <com.h6ah4i.android.widget.verticalseekbar.VerticalSeekBarWrapper
            android:layout_width="wrap_content"
            android:layout_height="match_parent"
            android:layout_centerHorizontal="true"
            android:layout_below="@+id/right">

            <com.h6ah4i.android.widget.verticalseekbar.VerticalSeekBar
                android:id="@+id/vsb_volume_right"
                android:layout_width="0dp"
                android:layout_height="0dp"
                android:maxHeight="9dp"
                android:minHeight="9dp"
                android:thumb="@drawable/drag_thumb_right"
                android:progressDrawable="@drawable/seekbar_progressbar"
                app:seekBarRotation="CW270" />
        </com.h6ah4i.android.widget.verticalseekbar.VerticalSeekBarWrapper>

*this issue does not happen with standard SeekBar object

[h6ah4i]

Thank you for the issue report. I will take a look at it.

[AdrianVidaurre]

I have the same issue when I implement two vertical seekbars.

[h6ah4i]

I think this is not an issue of this library. Unfortunately, it is a known bug of ViewPager.

[CalebMacdonaldBlack]

Use this in a wrapping view to disable pressing two vertical bars at once. android:splitMotionEvents="false"
