Android ViewPagerIndicator ========================== Paging indicator widgets that are compatible with the `ViewPager` from the [Android Support Library][2] to improve discoverability of content. Try out the sample application [on the Android Market][10]. ![ViewPagerIndicator Sample Screenshots][9] These widgets can also be used in conjunction with [ActionBarSherlock][3]! Usage ===== *For a working implementation of this project see the `sample/` folder.* 1. Include one of the widgets in your view. This should usually be placed adjacent to the `ViewPager` it represents. <com.viewpagerindicator.TitlePageIndicator android:id="@+id/titles" android:layout_height="wrap_content" android:layout_width="fill_parent" /> 2. In your `onCreate` method (or `onCreateView` for a fragment), bind the indicator to the `ViewPager`. //Set the pager with an adapter ViewPager pager = (ViewPager)findViewById(R.id.pager); pager.setAdapter(new TestAdapter(getSupportFragmentManager())); //Bind the title indicator to the adapter TitlePageIndicator titleIndicator = (TitlePageIndicator)findViewById(R.id.titles); titleIndicator.setViewPager(pager); 3. *(Optional)* If you use an `OnPageChangeListener` with your view pager you should set it in the indicator rather than on the pager directly. //continued from above titleIndicator.setOnPageChangeListener(mPageChangeListener); Theming ------- There are three ways to style the look of the indicators. 1. **Theme XML**. An attribute for each type of indicator is provided in which you can specify a custom style. 2. **Layout XML**. Through the use of a custom namespace you can include any desired styles. 3. **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][7]. 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][8] in Eclipse or ant. If you are a Maven user you can easily include the library by specifying it as a dependency: <dependency> <groupId>com.viewpagerindicator</groupId> <artifactId>library</artifactId> <version>2.4.1</version> <type>apklib</type> </dependency> This project depends on the `ViewPager` class which is available in the [Android Support Library][2] or [ActionBarSherlock][3]. Details for including one of those libraries is available on their respecitve web sites. Developed By ============ * Jake Wharton - <jakewharton@gmail.com> Credits ------- * [Patrik Åkerfeldt][1] - Author of [ViewFlow][4], a precursor to the ViewPager, which supports paged views and is the original source of both the title and circle indicators. * [Francisco Figueiredo Jr.][5] - Idea and [first implementation][6] for fragment support via ViewPager.
