Android PagerSlidingTabStrip (default Material Design)

Interactive paging indicator widget, compatible with the ViewPager from the Android Support Library.

------

Usage

For a working implementation of this project see the sample/ folder.

1. Include the following dependency to your gradle file.

    compile 'com.jpardogo.materialtabstrip:library:1.0.9'

Or add the library as a project. I tried to send a pull request, but looks like the original developer doesn't maintain it anymore.

2. Include the PagerSlidingTabStrip widget in your layout. This should usually be placed above the ViewPager it represents.

   <com.astuetz.PagerSlidingTabStrip android:id="@+id/tabs" android:layout_width="match_parent" android:layout_height="?attr/actionBarSize" android:background="?attr/colorPrimary" />

3. In your onCreate method (or onCreateView for a fragment), bind the widget to the ViewPager.

   // Initialize the ViewPager and set an adapter
   ViewPager pager = (ViewPager) findViewById(R.id.pager);
   pager.setAdapter(new TestAdapter(getSupportFragmentManager()));
   
   // Bind the tabs to the ViewPager
   PagerSlidingTabStrip tabs = (PagerSlidingTabStrip) findViewById(R.id.tabs);
   tabs.setViewPager(pager);
   

4. If your adapter implements the interface CustomTabProvider you can past you custom tab view/s. In case the the view returned contains the id R.id.psts_tab_title, this view should be a Textview and will be used to placed the title. If you don't want the library manage your TextView title for the tab, use a different id than R.id.psts_tab_title in your tab layout.

   If your adapter don't implements the interface CustomTabProvider the default tab will be use (That's a TextView with id R.id.psts_tab_title)

5. (Optional) If you use an OnPageChangeListener with your view pager you should set it in the widget rather than on the pager directly.

   // continued from above
   tabs.setOnPageChangeListener(mPageChangeListener);
   

Customization

From theme:

• android:textColorPrimary value (from your theme) will be applied automatically to tab's text color , underlineColor, dividerColor and indicatorColor, if any of these values are define in the xml layout.

Notes about some of the native attr:

• android:textSize Tab text size
• android:textColor Tab text color. Default textPrimaryColor with 150 alpha value.
• android:paddingLeft or android:paddingRight layout padding. If you apply both, they should be balanced. PR #69 have a good explanation of this behaviour.

Custom attr:

• pstsIndicatorColor Color of the sliding indicator
• pstsUnderlineColor Color of the full-width line on the bottom of the view
• pstsUnderlineHeight Height of the full-width line on the bottom of the view
• pstsDividerColor Color of the dividers between tabs
• pstsDividerPadding Top and bottom padding of the dividers
• pstsDividerWidth Stroke width of divider line, defaults to 0
• pstsIndicatorHeightHeight of the sliding indicator
• pstsTabPaddingLeftRight Left and right padding of each tab
• pstsScrollOffset Scroll offset of the selected tab
• pstsTabBackground Background drawable of each tab, should be a StateListDrawable
• pstsShouldExpand If set to true, each tab is given the same weight, default false
• pstsTextAllCaps If true, all tab titles will be upper case, default true
• pstsPaddingMiddle If true, the tabs start at the middle of the view (Like Newsstand google app)
• pstsTextStyle Set the text style, default bold
• pstsTextSelectedStyle Set the text style of the selected tab, default bold
• pstsTextAlphaSet the text alpha transparency, default 150. Range 0..255.
• pstsTextColorSelected Set selected tab text color. Default textPrimaryColor with 255 alpha value.

Almost all attributes have their respective getters and setters to change them at runtime , open an issue if you miss any.
