DrawablePagerTitleStrip

A PagerTitleStrip for Images

This is a version of a PagerTitleStrip that shows images instead of text. See color-picker for screenshots and an implementation example.

Requirements

Android support library 19 or newer

Example code

The ViewPager in this library is just a copy of the original ViewPager from the support library, but since the pager title strip classes depend on a few non-public members you'll we had to include it. That means you'll need to use the ViewPager provided by this library.

In your layout file replace android.support.v4.view.ViewPager by org.dmfs.android.view.ViewPager and android.support.v4.view.PagerTitleStrip by org.dmfs.android.view.DrawablePagerTitleStrip (or org.dmfs.android.view.DrawablePagerTabStrip) like so:

	<org.dmfs.android.view.ViewPager xmlns:android="http://schemas.android.com/apk/res/android"
	    android:id="@+id/pager"
	    android:layout_width="wrap_content"
	    android:layout_height="wrap_content" >

	    <org.dmfs.android.view.DrawablePagerTabStrip
		android:id="@+id/pager_title_strip"
		android:layout_width="match_parent"
		android:layout_height="wrap_content"
		android:layout_gravity="bottom"
		android:paddingBottom="4dip"
		android:paddingLeft="8dip"
		android:paddingRight="8dip"
		android:paddingTop="0dip" />

	</org.dmfs.android.view.ViewPager>

Don't forget to update any imports and types.

Now let your FragmentStatePagerAdapter or FragmentPagerAdapter implement IDrawableTitlePagerAdapter

	public class PalettesPagerAdapter extends FragmentStatePagerAdapter implements IDrawableTitlePagerAdapter
	{

	...


		@Override
		public Drawable getDrawableTitle(int position)
		{
			// return a drawable for this page
			...
			return someDrawable;
		}
	}

Be aware that neither DrawablePagerTabStrip nor DrawablePagerTitleStrip will cache the Drawables, so you better take care of that yourself. See PalettesPagerAdapter.java for an example.
