How to change the font size of tabhost in android

Question

How can the font size of the tabs be changed? I extend TabActivity for the tabs.

Answer 1

You can define themes, use styles to achieve this:

First you create the theme (name:CustomTheme) for your Activity in your res/values/styles.xml:

<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">20sp</item>     <item name="android:textStyle">bold</item> </style> 

Then in your androidManifest.xml you specify the theme above for your TabActivity or Activity containing your TabWidget:

<activity android:name="MyTabActivity" android:theme="@style/CustomTheme"> 

This will serve you with the output you want (of course you should change the size and style for your preference).

Answer 2

Its not pretty but try this Dirty Fix :

TabWidget tw = (TabWidget)tabHost.findViewById(android.R.id.tabs);
View tabView = tw.getChildTabViewAt(0);
TextView tv = (TextView)tabView.findViewById(android.R.id.title);
tv.setTextSize(20);

or

 //Do this to hack font size of title text
 LinearLayout ll = (LinearLayout) tabHost.getChildAt(0);
 TabWidget tw = (TabWidget) ll.getChildAt(0);

 // for changing the text size of first tab
 RelativeLayout rllf = (RelativeLayout) tw.getChildAt(0);
 TextView lf = (TextView) rllf.getChildAt(1);
 lf.setTextSize(21);
 lf.setPadding(0, 0, 0, 6);

Answer 3

Slightly generalized:

final TabWidget tw = (TabWidget)mTabHost.findViewById(android.R.id.tabs);
    for (int i = 0; i < tw.getChildCount(); ++i)
    {
        final View tabView = tw.getChildTabViewAt(i);
        final TextView tv = (TextView)tabView.findViewById(android.R.id.title);
        tv.setTextSize(20);
    }
