Android AutoNotifyViewPager

This project is an upgraded version of [ViewPager][1]. AutoNotifies your adapter when data get's changed.

##Prerequisites - android-support-v4.jar

Why?

- By default ViewPager's adapter should be notified using mAdapter.notifyDataSetChanged() if data get's changed after [setting adapter][2] to avoid [IllegalStateException][5] - It get's difficult to update your adapter when PagerAdapter is in other class, typically different *.java - Example : - In [this app][3], ListView's adapter & ViewPager's adapter share's same content. - When scrolled down to bottom of the page in ListView, GetMoreData is triggered, fetched, parsed & updated to ListView's adapter. - Seems easy, but when the user clicks & navigates to ViewPager after triggered and before updated, you end up in IllegalStateException as the data got changed but not notified. - This can be avoided having complex eventListeners, instead simply use AutoNotifyViewPager

When?

- Notifies your adapter when view get's changed

Not When!

- adapter get's content.

Usage

Import any one [*.jar][4] into /libs

In layout.xml

width="matchparent" android:layoutheight="matchparent" />

Instead of ~~ViewPager mPager~~ use AutoNotifyViewPager mPager

AutoNotifyViewPager mPager = (AutoNotifyViewPager) findViewById(R.id.pager); mPager.setAdapter(adapter);
