Android PagerSlidingTabStrip

This is forked by astuetz/PagerSlingTabStrip.

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

Try out the sample application on the Play Store.

Usage

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

1. Include the library as local library project or add the dependency in your build.gradle.

   dependencies { compile 'com.astuetz:pagerslidingtabstrip:1.0.1' }

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="48dip" />

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. (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);
   

5. (Optional) If you want to change tab title color when selected you should set attributes in the xml. (Added)

   <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:app="http://schemas.android.com/apk/res-auto"
      xmlns:tools="http://schemas.android.com/tools"
      android:layout_width="match_parent"
      android:layout_height="match_parent" >
   
      <com.astuetz.PagerSlidingTabStrip
        android:id="@+id/tabs"
        android:layout_width="match_parent"
        android:layout_height="48dp"
        app:pstsTabSwitch="true"
        app:pstsActivateTextColor="#FF666666"
        app:pstsDeactivateTextColor="#FFCCCCCC" />
   
      ...
   </RelativeLayout>
   

6. (Optional) If you want to change tab icon image when selected you should set pstsTabSwitch attribute in the xml and prepare drawable selector. (Added)

    <com.astuetz.PagerSlidingTabStrip
        android:id="@+id/tabs"
        android:layout_width="match_parent"
        android:layout_height="48dp"
        app:pstsTabSwitch="true" />
   
    ...
   

Customization

To not just look like another Play Store styled app, go and adjust these values to match your brand:

• pstsIndicatorColor Color of the sliding indicator
• pstsUnderlineColor Color of the full-width line on the bottom of the view
• pstsDividerColor Color of the dividers between tabs
• pstsIndicatorHeightHeight of the sliding indicator

• pstsDividerPadding Top and bottom padding of the dividers
• 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
• pstsTabSwitch When a tab is selected, the drawable selector icon or the text color of the Tab title can be modified (Added)
• pstsTextActivateColor The Title color of selected Tab (Added)
