(Optional) If you use an
OnPageChangeListenerwith your view pager you should set it in the indicator rather than on the pager directly.
//continued from above titleIndicator.setOnPageChangeListener(mPageChangeListener);
There are three ways to style the look of the indicators.
- Theme XML. An attribute for each type of indicator is provided in which you can specify a custom style.
- Layout XML. Through the use of a custom namespace you can include any desired styles.
- Object methods. Both styles have getters and setters for each style attribute which can be changed at any point.
Each indicator has a demo which creates the same look using each of these methods.
Including In Your Project
Android-ViewPagerIndicator is presented as an Android library project. A standalone JAR is not possible due to the theming capabilities offered by the indicator widgets.
You can include this project by referencing it as a library project in Eclipse or ant. If you are a Maven user, artifacts will be deployed to a repo once the project hits the 1.0 milestone.
This project depends on the
ViewPager class which is available in the
Android Compatibility Library or ActionBarSherlock. Details for
including one of those libraries is available on their respecitve web sites.
