Change the text size in tab in android

Question

I've been facing the issue of text size in tab bar. Below is the image,

And here is my code,

MainActivity.java

public class MainActivity extends Activity implements OnTabChangeListener, OnPageChangeListener{  
    private TabHost tabHost;  
    private ViewPager pager; 

 @Override  
 public void onCreate(Bundle savedInstanceState) {  
   super.onCreate(savedInstanceState);  
   setContentView(R.layout.activity_main);  
   tabHost = (TabHost)findViewById(android.R.id.tabhost);  
   pager = (ViewPager) findViewById(R.id.pager);  

   tabHost.setup();  
   TabWidget tabwidget=tabHost.getTabWidget();

   TabSpec spec = tabHost.newTabSpec("tab1");  
   spec.setContent(R.id.tab1);  
   spec.setIndicator("Check In");  
   tabHost.addTab(spec);  

   spec = tabHost.newTabSpec("tab2");  
   spec.setContent(R.id.tab2);  
   spec.setIndicator("Buddies");  
   tabHost.addTab(spec);  

   spec = tabHost.newTabSpec("tab3");  
   spec.setContent(R.id.tab3);  
   spec.setIndicator("Recommendation");  
   tabHost.addTab(spec); 

   spec = tabHost.newTabSpec("tab4");  
   spec.setContent(R.id.tab4);  
   spec.setIndicator("Feed");  
   tabHost.addTab(spec); 

   spec = tabHost.newTabSpec("tab5");  
   spec.setContent(R.id.tab5);  
   spec.setIndicator("Last");  
   tabHost.addTab(spec);

   pager.setAdapter(new MyPagerAdapter(this));  
   pager.setOnPageChangeListener(this);  
   tabHost.setOnTabChangedListener(this);  

 }  
    @Override  
    public void onTabChanged(String tabId){  
         int pageNumber = 0;  
         if(tabId.equals("tab1"))
         {  
              pageNumber = 0;  

         }

         else if(tabId.equals("tab2"))
         {  
              pageNumber = 1;

         }

         else if(tabId.equals("tab3"))
         {  
              pageNumber = 2;  

         }

         else if(tabId.equals("tab4"))
         {  
              pageNumber = 3;  


         }

         else if(tabId.equals("tab5"))
         {  
              pageNumber = 4;  

         }
         else
         {  
              pageNumber = 0;  

         }  

         pager.setCurrentItem(pageNumber);  
    } 

    @Override  
    public void onPageSelected(int pageNumber) {  
         tabHost.setCurrentTab(pageNumber); 

    }
    @Override
    public void onPageScrollStateChanged(int arg0) {


    }
    @Override
    public void onPageScrolled(int arg0, float arg1, int arg2) {


    }
    }

activity_main.xml

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

    <LinearLayout
        android:layout_width="match_parent"

                android:visibility="gone" />

            <FrameLayout
                android:id="@+id/tab5"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:visibility="gone" />
        </FrameLayout>

        <android.support.v4.view.ViewPager

            android:layout_width="match_parent"
            android:layout_height="wrap_content" />
    </LinearLayout>

</TabHost>

I want whole text to be set in each tab, how can I do that?

I've been trying this code to change the text size and getting this result,

code

 TextView x = (TextView) tabHost.getTabWidget().getChildAt(0).findViewById(android.R.id.title);
   x.setTextSize(10);
   tabHost.getTabWidget().getChildAt(0).getLayoutParams().width = 100;

   TextView x1 = (TextView) tabHost.getTabWidget().getChildAt(1).findViewById(android.R.id.title);
   x1.setTextSize(10);
   tabHost.getTabWidget().getChildAt(1).getLayoutParams().width = 90;

   TextView x2 = (TextView) tabHost.getTabWidget().getChildAt(2).findViewById(android.R.id.title);
   x2.setTextSize(10);
   tabHost.getTabWidget().getChildAt(2).getLayoutParams().width = 100;

   TextView x3 = (TextView) tabHost.getTabWidget().getChildAt(3).findViewById(android.R.id.title);
   x3.setTextSize(10);
   tabHost.getTabWidget().getChildAt(3).getLayoutParams().width = 40;

   TextView x4 = (TextView) tabHost.getTabWidget().getChildAt(4).findViewById(android.R.id.title);
   x4.setTextSize(10);
   tabHost.getTabWidget().getChildAt(4).getLayoutParams().width = 40;

Image of result

But I want the output as this image

As per above image, my tab widget should be movable, how can I do this?

Answer 1

Easy wasy to do Just add style to ur xml file declare the size in which you want.

<style name="CustomTheme" parent="@android:style/Theme">
    <item name="android:tabWidgetStyle">@style/CustomTabWidget</item>
</style>
<style name="CustomTabWidget" parent="@android:style/Widget.TabWidget">
    <item name="android:textAppearance">@style/CustomTabWidgetText</item>
</style>
<style name="CustomTabWidgetText" 
    parent="@android:style/TextAppearance.Widget.TabWidget">
    <item name="android:textSize">100sp</item>
    <item name="android:textStyle">**strong text**</item>
</style>

Dont forget to add theme with style name in manifast file.

Answer 3

<android.support.design.widget.TabLayout
        android:id="@+id/tabs"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:tabMode="scrollable"/>

Use app:tabMode="scrollable"

Answer 4

 app:tabMode="scrollable"
 app:tabGravity="fill"

Use this line in your tab xml and it will do it.

Answer 5

You can also customize the text and background of a your tabs. See this blog for a very good tutorial on how to do it.

Answer 6

Just put the TabLayout inside a HorizontalScrollView:

<HorizontalScrollView
             android:layout_width="match_parent"
             android:layout_height="wrap_content">
                <android.support.design.widget.TabLayout
                 android:id="@+id/tabs"
                 android:layout_width="wrap_content"
                 android:layout_height="wrap_content" />
    </HorizontalScrollView>
