Android AutoNotifyViewPager

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

##Prerequisites

• android-support-v4.jar

Why?

• By default ViewPager's adapter should be notified using <kbd>mAdapter.notifyDataSetChanged()</kbd> if data get's changed after setting adapter to avoid IllegalStateException
• It get's difficult to update your adapter when PagerAdapter is in other class, typically different <kbd>*.java</kbd>
• <u>Example</u> :
  • In this app, 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 <u>when view get's changed</u>

Not When!

• adapter get's content.

Usage

Import any one *.jar into /libs

In layout.xml

<com.venomvendor.library.AutoNotifyViewPager 
	android:id="@+id/pager"
	android:layout_width="match_parent"
	android:layout_height="match_parent" />

Instead of <s>ViewPager mPager</s> use <kbd>AutoNotifyViewPager mPager</kbd>

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