Android PagerSlidingTabStrip (default Material Design)

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

PagerSlidingTabStrip Sample Material ------ PagerSlidingTabStrip Sample Material

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.

  1. 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" />

  2. 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);

  3. 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)

  4. (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 the tab's text color (Selected tab with 255 alpha and non selected tabs with 150 alpha) , underlineColor, dividerColor and indicatorColor, if the values are not define on the xml layout.

Notes about some of the native attr:

  • android:textColor Non selected tabs text color. If you DO define textColor It will be apply to NON selected tabs and NO ALPHA will be applied to them, the colour you define is the one you will see. If you want to define a half transparent color in textColor, you can pass #80FFFFFF (That's an example for half transparent white)
  • android:textSize Tab text size
  • 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. textPrimaryColor will be it's default color value.
  • pstsUnderlineColor Color of the full-width line on the bottom of the view. textPrimaryColor will be it's default color value.
  • pstsUnderlineHeight Height of the full-width line on the bottom of the view.
  • pstsTextAlpha Set the text alpha transparency for non selected tabs. Range 0..255. 150 is it's default value. It WON'T be use if textColor is defined in the layout. If textColor is NOT defined, It will be apply to the non selected tabs.
  • pstsTextColorSelected Set selected tab text color. textPrimaryColor will be it's default color value.
  • pstsTextStyle Set the text style, default bold.
  • pstsTextSelectedStyle Set the text style of the selected tab, default bold.
  • pstsTextAllCaps If true, all tab titles will be upper case, default true.
  • pstsDividerColor Color of the dividers between tabs. textPrimaryColor will be it's default color value.
  • 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.
  • pstsPaddingMiddle If true, the tabs start at the middle of the view (Like Newsstand google app).

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