So I'm using ActionsContentView My goal is to implement a ViewPager element within it. Utilizing just one other view. Has anybody done this with this project? The author says it's not easily done, and seeing how I'm still very new in Android programming (migrated from iOS) I feel I need help.
I have ready the docs on ViewPager, but couldn't seem to make them link up properly.
And help would be appreciated.
UPDATE: 12/23
So I managed to get most of this working on the demo app using this tutorial http://looksok.wordpress.com/2013/10/26/android-support-v4-viewpager-tutorial-including-source-code/, however, when I click links in the drawer, they don't update in main view.
This one part below will respond to clicks when its set in RelativeLayout, but ViewPager is broken, but when set in Linearlayout, ViewPager works, but links wont respond.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/content"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<android.support.v4.view.ViewPager
android:id="@+id/myViewPager"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
</LinearLayout>
Another thing I could be thinking that in my MainActivity, it's not updating the proper view. It clicks, closes the drawer and then nothing happens. Heres my MainActivity.
