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

</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?
TextView x = (TextView) tabHost.getTabWidget().getChildAt(0).findViewById(android.R.id.title);
x.setTextSize(25);
refer the below link for more detail
You can use the TabLayout and Viewpager instead, and set the tabMode to scrollable, see code below:
<android.support.design.widget.TabLayout
android:id="@+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabGravity="center"
app:tabMode="scrollable" />
app:tabMode="scrollable"
app:tabGravity="fill"
Use this line in your tab xml and it will do it.
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.
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.
<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"
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>
<TabHost
android:id="@+id/tabhost"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<TabWidget
android:id="@android:id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
>
</TabWidget>
<FrameLayout
android:id="@android:id/tabcontent"
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_weight="0" />
<android.support.v4.view.ViewPager
android:id="@+id/viewpager"
android:layout_width="match_parent"
android:layout_height="wrap_content"
/>
</LinearLayout>
</TabHost>
Code:
for(int i=0;i<tabhost.getTabWidget().getChildCount();i++)
{
TextView tv = (TextView) tabhost.getTabWidget().getChildAt(i).findViewById(android.R.id.title);
tv.setTextColor(Color.parseColor(SM.getTheme_colour()));
tv.setTypeface(font_k);
}
This code works for tabhost change text color, type face (font style) and also text size.
