Persistent Exception onResume about viewpagerindicator HOT 8 CLOSED

I'm seeing something very similar. It doesn't happen every time, but I did notice that the viewpager was showing the correct view from onResume, but the indicator wasn't on the correct item, it was reset to the first index.

@leowhiterussian: Are you using version 1.0 or a specific commit? Line 304 doesn't seem to line up with 1.0 nor the current dev branch. There is a lot of calls to ArrayList.get() in onDraw and I am trying to pin down exactly which one(s) are going bad.

@neekers: That stacktrace doesn't seem to be related to the library but rather having something to do with the header view on a ListView.

from viewpagerindicator.

@JakeWharton I believe I am using 1.0. Sorry I forgot that I added some of my own code, which changed the line numbers. It is happening in onDraw, whenever it tries to do bounds.get( ). For whatever reason it seems that GC clears the titles at some point, but the position is remember. So it tries to get the 5th position of a 1 length list. I have mitigated the crash by surrounding all the bounds.get( ) calls with try/catch . Was hoping for a better solution than that though.

from viewpagerindicator.

Not sure why this issue was closed as reading through the comments there doesn't seem to be a permanent solution only a temporary patch with try/catch clauses. Perhaps I've overlooked something? This might also be same as issue #24 - #24 ...
I'm also experiencing this issue, although right now the occurrence is not as common.

Stacktrace - Case #1:
java.lang.IndexOutOfBoundsException: Invalid index 9, size is 9
1 at java.util.ArrayList.throwIndexOutOfBoundsException(ArrayList.java:251)
2 at java.util.ArrayList.get(ArrayList.java:304)
3 at com.viewpagerindicator.TitlePageIndicator.onDraw(TitlePageIndicator.java:319)

Stacktrace - Case #2:
java.lang.IndexOutOfBoundsException: Invalid index 10, size is 7
1 at java.util.ArrayList.throwIndexOutOfBoundsException(ArrayList.java:257)
2 at java.util.ArrayList.get(ArrayList.java:311)
3 at com.viewpagerindicator.TitlePageIndicator.onDraw(TitlePageIndicator.java:319)

Line 319 from TitlePageIndicator.class:
RectF curPageBound = bounds.get(mCurrentPage);
Seems to be the same issue already mentioned in this thread, onResume triggers an incorrect value to be pulled when bounds.get method.

Is there a better way to fix this other than throw try/clause statements around it and silently drop the error?

from viewpagerindicator.

This issue was closed because it indeed was the same as #24 and a fix was added and released as 2.1.0.

from viewpagerindicator.

Thank you! This project is very very helpful!
Will update on my end.

@JakeWharton : I still face this strange indexoutofbound exception with the latest version of 2.3.1. I am not sure what causes it. Also i have embedded the stacktrace of it below. Hoping for better response. Thanks.
