View source for Change Tab Color

This is sample code to change the tab background color.

Use the below line of code in onCreate() to display in first time.

 for(int i=0;i<tabHost.getTabWidget().getChildCount();i++)
 {
      tabHost.getTabWidget().getChildAt(i).setBackgroundColor(Color.parseColor("#7392B5"));
 }

To set different color for current selected tab. use

 tabHost.getTabWidget().getChildAt(0).setBackgroundColor(Color.parseColor("#4E4E9C"));

Here 0 position is the first tab.

When you change the tab selection you need to change your selected color to that current tab & replace the default color to other tab. For that use OnTabChangeListener(). These method will be called when you change the tab selection.

 tabHost.setOnTabChangedListener(new OnTabChangeListener()
 {
      public void onTabChanged(String tabId)
      {
           for(int i=0;i<tabHost.getTabWidget().getChildCount();i++)
           {
 
                // Change the background color of all the tabs.
                tabHost.getTabWidget().getChildAt(i).setBackgroundColor(Color.parseColor("#000000"));
           }
           tabHost.getTabWidget().getChildAt(tabHost.getCurrentTab()).setBackgroundColor(Color.parseColor("#4E4E9C"));
      }
 });

When using Color.parseColor, use 
 import android.graphics.Color;
