Change height/width

[vados60]

Hello!

Is there any chance to set number of currently visible rows except selected one?
Or is there any chance to hide all other rows except selected?

if I set
app:np_wheelItemCount="1"

when try to scroll the app crashes with IndexOutOfBounds exception
java.lang.ArrayIndexOutOfBoundsException: length=1; index=-1
at com.shawnlin.numberpicker.NumberPicker.incrementSelectorIndices(NumberPicker.java:1695)

I have the same issue.

Also, the control uses the space above and below as if would have more items to show.

Hi @vados60,
Have you tried setting the text color to transparent?
numberPicker.setTextColorResource(android.R.color.transparent);
or
app:np_textColor="@android:color/transparent"

And no need to set the wheel item count to 1.

I met the same issue, and I think it is a bug.
I have checked the code. When app:np_wheelItemCount is set as 1, the size of selectorIndices will be 0(line 2113), then the IndexOutOfBound will happen in line 1775.

I also have the same bug. A temporary kludge proposed by @ShawnLin013 works.
