Tabbed Activity in Android Studio

Question

I read somewhere that the tabbed activity in the android studio has some deprecated code. So, should I use it or not? And are there other new ways to achieve the same?

Answer 1

Why don't you try Material design Sliding Tabs? They provide better view and and interactive UI.

Step 1: download these two files copy as it is in Android Studio:

first and second

Step 2: in color.xml set the color scheme as per your requirement:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="ColorPrimary">#e62117</color>
    <color name="ColorPrimaryDark">#c31c13</color>
    <color name="tabsScrollColor">#8a140e</color>

</resources>

Step 3: Create toolbar.xml

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar
    android:layout_height="wrap_content"
    android:layout_width="match_parent"
    android:background="@color/ColorPrimary"
    android:elevation="2dp"
    android:theme="@style/Base.ThemeOverlay.AppCompat.Dark"
    xmlns:android="http://schemas.android.com/apk/res/android" />

Step 4: in activity_main.xml put the following code:

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

    <include
        android:id="@+id/tool_bar"
        layout="@layout/tool_bar"
        android:layout_height="wrap_content"
        android:layout_width="match_parent"
        />

    <com.example.slidingtab.SlidingTabLayout
        android:id="@+id/tabs"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:elevation="2dp"
        android:background="@color/ColorPrimary"/>
 <android.support.v4.view.ViewPager
    android:id="@+id/pager"

    android:layout_height="match_parent"
    android:layout_width="match_parent"
    android:layout_weight="1"
    />

Step 5: Now create layouts for tabs as tab_1.xml, tab_2.xml:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">


    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textAppearance="?android:attr/textAppearanceMedium"
        android:text="You Are In Tab 1"
        android:id="@+id/textView"
        android:layout_centerVertical="true"
        android:layout_centerHorizontal="true" />

</RelativeLayout>


</LinearLayout>  

Step 6: Similarly create two fragments as fragment_one.java and fragment_two.java

public class Tab1 extends Fragment {

    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View v =inflater.inflate(R.layout.tab_1,container,false);
        return v;
    }
}

Step 7: ViewPager class:

public class ViewPagerAdapter extends FragmentStatePagerAdapter {

    CharSequence Titles[]; // This will Store the Titles of the Tabs which are Going to be passed when ViewPagerAdapter is created
    int NumbOfTabs; // Store the number of tabs, this will also be passed when the ViewPagerAdapter is created


    // Build a Constructor and assign the passed Values to appropriate values in the class
    public ViewPagerAdapter(FragmentManager fm,CharSequence mTitles[], int mNumbOfTabsumb) {
        super(fm);

        this.Titles = mTitles;
        this.NumbOfTabs = mNumbOfTabsumb;

    }

    //This method return the fragment for the every position in the View Pager
    @Override
    public Fragment getItem(int position) {

        if(position == 0) // if the position is 0 we are returning the First tab
        {
            Tab1 tab1 = new Tab1();
            return tab1;
        }
        else             // As we are having 2 tabs if the position is now 0 it must be 1 so we are returning second tab
        {
            Tab2 tab2 = new Tab2();
            return tab2;
        }


    }

    // This method return the titles for the Tabs in the Tab Strip

    @Override
    public CharSequence getPageTitle(int position) {
        return Titles[position];
    }

    // This method return the Number of tabs for the tabs Strip

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

Step 8: The final step:

public class MainActivity extends ActionBarActivity {

    // Declaring Your View and Variables

    Toolbar toolbar;
    ViewPager pager;
    ViewPagerAdapter adapter;
    SlidingTabLayout tabs;
    CharSequence Titles[]={"Home","Events"};
    int Numboftabs =2;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);


        // Creating The Toolbar and setting it as the Toolbar for the activity

        toolbar = (Toolbar) findViewById(R.id.tool_bar);
        setSupportActionBar(toolbar);


        // Creating The ViewPagerAdapter and Passing Fragment Manager, Titles fot the Tabs and Number Of Tabs.
        adapter =  new ViewPagerAdapter(getSupportFragmentManager(),Titles,Numboftabs);

        // Assigning ViewPager View and setting the adapter
        pager = (ViewPager) findViewById(R.id.pager);
        pager.setAdapter(adapter);

        // Assiging the Sliding Tab Layout View
        tabs = (SlidingTabLayout) findViewById(R.id.tabs);
        tabs.setDistributeEvenly(true); // To make the Tabs Fixed set this true, This makes the tabs Space Evenly in Available width

        // Setting Custom Color for the Scroll bar indicator of the Tab View
        tabs.setCustomTabColorizer(new SlidingTabLayout.TabColorizer() {
            @Override
            public int getIndicatorColor(int position) {
                return getResources().getColor(R.color.tabsScrollColor);
            }
        });

        // Setting the ViewPager For the SlidingTabsLayout
        tabs.setViewPager(pager);

 }

    }
