Questions:

I’m trying to get the new TabLayout in the android design library working.

I’m following this post:

http://android-developers.blogspot.com/2015/05/android-design-support-library.html

and the documentation:

http://developer.android.com/reference/android/support/design/widget/TabLayout.html

And have come up with the following code in my activity but the tablayout isn’t showing up when I run the activity.

I tried adding in the activity layout file, but it says it can’t find that xml tag.

public class TabActivity extends BaseActivity {

    SectionPagerAdapter mSectionsPagerAdapter;
    ViewPager mViewPager;

    @Override
    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_tab);

        LinearLayout v = (LinearLayout)findViewById(R.id.tabContainer);

        TabLayout tabLayout = new TabLayout(this);
        tabLayout.addTab(tabLayout.newTab().setText("Tab 1"));
        tabLayout.addTab(tabLayout.newTab().setText("Tab 2"));
        tabLayout.addTab(tabLayout.newTab().setText("Tab 3"));

        tabLayout.setLayoutParams(new LinearLayout.LayoutParams(FrameLayout.LayoutParams.MATCH_PARENT, 50));

        v.addView(tabLayout);

        mSectionsPagerAdapter = new SectionPagerAdapter(getFragmentManager());

        mViewPager = (ViewPager) findViewById(R.id.pager);
        mViewPager.setAdapter(mSectionsPagerAdapter);

        tabLayout.setupWithViewPager(mViewPager);
        mViewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));

    }

    public class SectionPagerAdapter extends FragmentPagerAdapter {

        private String TAG = "SectionPagerAdapter";

        public SectionPagerAdapter(FragmentManager fm) {
            super(fm);
        }

        @Override
        public Fragment getItem(int position)
        {
            return new Fragment();
        }

        @Override
        public int getCount() {
            return 2;
        }

        @Override
        public CharSequence getPageTitle(int position) {
            Locale l = Locale.getDefault();
            switch (position) {
                case 0:
                    return "test";
                case 1:
                    return "test";
                case 2:
            }
            return null;
        }
    }
}

Added the following to my gradle file

 compile 'com.android.support:design:22.2.0'

I’ve just managed to setup new TabLayout, so here are the quick steps to do this (ノ◕ヮ◕)ノ*:・゚✧

  1. Add dependencies inside your build.gradle file:

    dependencies {
        compile 'com.android.support:design:23.1.1'
    }
    
  2. Add TabLayout inside your layout

    <?xml version="1.0" encoding="utf-8"?>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          android:orientation="vertical">
    
        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:background="?attr/colorPrimary"/>
    
        <android.support.design.widget.TabLayout
            android:id="@+id/tab_layout"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"/>
    
        <android.support.v4.view.ViewPager
            android:id="@+id/pager"
            android:layout_width="match_parent"
            android:layout_height="match_parent"/>
    
    </LinearLayout>
    
  3. Setup your Activity like this:

    import android.os.Bundle;
    import android.support.design.widget.TabLayout;
    import android.support.v4.app.Fragment;
    import android.support.v4.app.FragmentManager;
    import android.support.v4.app.FragmentPagerAdapter;
    import android.support.v4.view.ViewPager;
    import android.support.v7.app.AppCompatActivity;
    import android.support.v7.widget.Toolbar;
    
    public class TabLayoutActivity extends AppCompatActivity {
    
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_pull_to_refresh);
    
            Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
            TabLayout tabLayout = (TabLayout) findViewById(R.id.tab_layout);
            ViewPager viewPager = (ViewPager) findViewById(R.id.pager);
    
            if (toolbar != null) {
                setSupportActionBar(toolbar);
            }
    
            viewPager.setAdapter(new SectionPagerAdapter(getSupportFragmentManager()));
            tabLayout.setupWithViewPager(viewPager);
        }
    
        public class SectionPagerAdapter extends FragmentPagerAdapter {
    
            public SectionPagerAdapter(FragmentManager fm) {
                super(fm);
            }
    
            @Override
            public Fragment getItem(int position) {
                switch (position) {
                    case 0:
                        return new FirstTabFragment();
                    case 1:
                    default:
                        return new SecondTabFragment();
                }
            }
    
            @Override
            public int getCount() {
                return 2;
            }
    
            @Override
            public CharSequence getPageTitle(int position) {
                switch (position) {
                    case 0:
                        return "First Tab";
                    case 1:
                    default:
                        return "Second Tab";
                }
            }
        }
    
    }

Answers:

I had to collect information from various sources to put together a functioning TabLayout. The following is presented as a complete use case that can be modified as needed.

Make sure the module build.gradle file contains a dependency on com.android.support:design.

dependencies {
    compile 'com.android.support:design:23.1.1'
}

In my case, I am creating an About activity in the application with a TabLayout. I added the following section to AndroidMainifest.xml. Setting the parentActivityName allows the home arrow to take the user back to the main activity.

<!-- android:configChanges="orientation|screenSize" makes the activity not reload when the orientation changes. -->
<activity
    android:name=".AboutActivity"
    android:label="@string/about_app"
    android:theme="@style/MyApp.About"
    android:parentActivityName=".MainActivity"
    android:configChanges="orientation|screenSize" >

    <!-- android.support.PARENT_ACTIVITY is necessary for API <= 15. -->
    <meta-data
        android:name="android.support.PARENT_ACTIVITY"
        android:value=".MainActivity" />
</activity>

styles.xml contains the following entries. This app has a white AppBar for the main activity and a blue AppBar for the About activity. We need to set colorPrimaryDark for the About activity so that the status bar above the AppBar is blue.

<style name="MyApp" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="colorAccent">@color/blue</item>
</style>

<style name="MyApp.About" />

<!-- ThemeOverlay.AppCompat.Dark.ActionBar" makes the text and the icons in the AppBar white. -->
<style name="MyApp.DarkAppBar" parent="ThemeOverlay.AppCompat.Dark.ActionBar" />

<style name="MyApp.AppBarOverlay" parent="ThemeOverlay.AppCompat.ActionBar" />

<style name="MyApp.PopupOverlay" parent="ThemeOverlay.AppCompat.Light" />

There is also a styles.xml (v19). It is located at src/main/res/values-v19/styles.xml. This file is only applied if the API of the device is >= 19.

<!-- android:windowTranslucentStatus requires API >= 19.  It makes the system status bar transparent.
  When it is specified the root layout should include android:fitsSystemWindows="true".
  colorPrimaryDark goes behind the status bar, which is then darkened by the overlay. -->
<style name="MyApp.About">
    <item name="android:windowTranslucentStatus">true</item>
    <item name="colorPrimaryDark">@color/blue</item>
</style>

AboutActivity.java contains the following code. In my case I have a fixed number of tabs (7) so I could remove all the code dealing with dynamic tabs.

import android.os.Bundle;
import android.support.design.widget.TabLayout;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
import android.support.v4.view.ViewPager;
import android.support.v7.app.ActionBar;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;

public class AboutActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.about_coordinatorlayout);

        // We need to use the SupportActionBar from android.support.v7.app.ActionBar until the minimum API is >= 21.
        Toolbar supportAppBar = (Toolbar) findViewById(R.id.about_toolbar);
        setSupportActionBar(supportAppBar);

        // Display the home arrow on supportAppBar.
        final ActionBar appBar = getSupportActionBar();
        assert appBar != null;// This assert removes the incorrect warning in Android Studio on the following line that appBar might be null.
        appBar.setDisplayHomeAsUpEnabled(true);

        //  Setup the ViewPager.
        ViewPager aboutViewPager = (ViewPager) findViewById(R.id.about_viewpager);
        assert aboutViewPager != null; // This assert removes the incorrect warning in Android Studio on the following line that aboutViewPager might be null.
        aboutViewPager.setAdapter(new aboutPagerAdapter(getSupportFragmentManager()));

        // Setup the TabLayout and connect it to the ViewPager.
        TabLayout aboutTabLayout = (TabLayout) findViewById(R.id.about_tablayout);
        assert aboutTabLayout != null; // This assert removes the incorrect warning in Android Studio on the following line that aboutTabLayout might be null.
        aboutTabLayout.setupWithViewPager(aboutViewPager);
    }

    public class aboutPagerAdapter extends FragmentPagerAdapter {
        public aboutPagerAdapter(FragmentManager fm) {
            super(fm);
        }

        @Override
        // Get the count of the number of tabs.
        public int getCount() {
            return 7;
        }

        @Override
        // Get the name of each tab.  Tab numbers start at 0.
        public CharSequence getPageTitle(int tab) {
            switch (tab) {
                case 0:
                    return getString(R.string.version);

                case 1:
                    return getString(R.string.permissions);

                case 2:
                    return getString(R.string.privacy_policy);

                case 3:
                    return getString(R.string.changelog);

                case 4:
                    return getString(R.string.license);

                case 5:
                    return getString(R.string.contributors);

                case 6:
                    return getString(R.string.links);

                default:
                    return "";
            }
        }

        @Override
        // Setup each tab.
        public Fragment getItem(int tab) {
            return AboutTabFragment.createTab(tab);
        }
    }
}

AboutTabFragment.java is used to populate each tab. In my case, the first tab has a LinearLayout inside of a ScrollView and all the others have a WebView as the root layout.

import android.os.Build;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.webkit.WebView;
import android.widget.TextView;

public class AboutTabFragment extends Fragment {
    private int tabNumber;

    // AboutTabFragment.createTab stores the tab number in the bundle arguments so it can be referenced from onCreate().
    public static AboutTabFragment createTab(int tab) {
        Bundle thisTabArguments = new Bundle();
        thisTabArguments.putInt("Tab", tab);
        AboutTabFragment thisTab = new AboutTabFragment();
        thisTab.setArguments(thisTabArguments);
        return thisTab;
    }

    @Override
    public void onCreate (Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        // Store the tab number in tabNumber.
        tabNumber = getArguments().getInt("Tab");
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View tabLayout;

        // Load the about tab layout.  Tab numbers start at 0.
        if (tabNumber == 0) {
            // Setting false at the end of inflater.inflate does not attach the inflated layout as a child of container.
            // The fragment will take care of attaching the root automatically.
            tabLayout = inflater.inflate(R.layout.about_tab_version, container, false);
        } else { // load a WebView for all the other tabs.  Tab numbers start at 0.
            // Setting false at the end of inflater.inflate does not attach the inflated layout as a child of container.
            // The fragment will take care of attaching the root automatically.
            tabLayout = inflater.inflate(R.layout.about_tab_webview, container, false);
            WebView tabWebView = (WebView) tabLayout;

            switch (tabNumber) {
                case 1:
                tabWebView.loadUrl("file:///android_asset/about_permissions.html");
                    break;

                case 2:
                    tabWebView.loadUrl("file:///android_asset/about_privacy_policy.html");
                    break;

                case 3:
                    tabWebView.loadUrl("file:///android_asset/about_changelog.html");
                    break;

                case 4:
                    tabWebView.loadUrl("file:///android_asset/about_license.html");
                    break;

                case 5:
                    tabWebView.loadUrl("file:///android_asset/about_contributors.html");
                    break;

                case 6:
                    tabWebView.loadUrl("file:///android_asset/about_links.html");
                    break;

                default:
                    break;
            }
        }

        return tabLayout;
    }
}

I try to solve here is my code.

first add dependency in build.gradle(app).

dependencies {
    compile 'com.android.support:design:23.1.1'
}

Create PagerAdapter.class

public class PagerAdapter extends FragmentPagerAdapter {

        setSupportActionBar(toolbar);

        TabLayout tabLayout = (TabLayout) findViewById(R.id.tab_layout);


        final ViewPager viewPager = (ViewPager) findViewById(R.id.pager);
         pager = new Pager(getSupportFragmentManager());

        pager.addFragment(new FragmentOne(), "One");

        viewPager.setAdapter(pager);

        tabLayout.setupWithViewPager(viewPager);

        viewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));

        tabLayout.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {

            public void onTabReselected(TabLayout.Tab tab) {

            }
        });
    }
}

and finally create fragment to add in viewpager

crate fragment_one.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <TextView
        android:text="Location"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

</LinearLayout>

Create FragmentOne.class

public class FragmentOne extends Fragment {

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

        View view = inflater.inflate(R.layout.fragment_one, container,false);
        return view;

I am facing some issue with menu change when fragment changes in ViewPager. I ended up implemented below code.

DashboardPagerAdapter

public class DashboardPagerAdapter extends FragmentPagerAdapter {

private List<EnumUtils.Module> moduleList;
private Fragment mCurrentFragment = null;

public DashboardPagerAdapter(FragmentManager fm, List<EnumUtils.Module> moduleList){
    super(fm);
    this.moduleList = moduleList;
}

@Override
public Fragment getItem(int position) {
    return EnumUtils.Module.getDashboardFragment(moduleList.get(position));
}

@Override
public int getCount() {
    return moduleList.size();
}

@Override
public void setPrimaryItem(ViewGroup container, int position, Object object) {
    if (getCurrentFragment() != object) {
        mCurrentFragment = ((Fragment) object);
    }
    super.setPrimaryItem(container, position, object);
}

public Fragment getCurrentFragment() {
    return mCurrentFragment;
}

public int getModulePosition(EnumUtils.Module moduleName){
    for(int x = 0 ; x < moduleList.size() ; x++){
        if(moduleList.get(x).equals(moduleName))
            return x;
    }
    return -1;
}

}

And in each page of Fragment setHasOptionMenu(true) in onCreate and implement onCreateOptionMenu. then it will work properly.
