I am now working with Android TabWidget.
I build this TabWidget based on http://mobileorchard.com/android-app-development-tabbed-activities/
I\'ve already add background
If using a TabLayout object then hiding the indicator can be achieved as follows:
tabLayout.setSelectedTabIndicatorColor(getResources().getColor(R.color.transparent, null));
Cheers.
I add this and finally works :
tabHost.getTabWidget().getChildTabViewAt(0).setBackgroundDrawable(null);
tabHost.getTabWidget().getChildTabViewAt(1).setBackgroundDrawable(null);
tabHost.getTabWidget().getChildTabViewAt(2).setBackgroundDrawable(null);
tabHost.getTabWidget().getChildTabViewAt(3).setBackgroundDrawable(null);
tabHost.setCurrentTab(0);
