Android Question TabHost change Tab Color

Have a look at the TabHostExtras lib ... https://www.b4x.com/android/forum/threads/tabhostextras.11056/

There is a way to do so without using lib ... but on holidays with slow internet and unable to locate.

Note that TabHost is not used too much anymore.
TabStripViewPager is more useful in most cases: https://www.b4x.com/android/forum/threads/63975/#content

Verry, verry nice Erel and mangojack Thanks.

ehm Erel, i dont have this Component in my Designer, is that Normal in the neweset version?

@Erel

Have you downloaed the Library files from the link @Erel supplied ?,
copy the.xml and .jar files to your additional library folder then make reference to the lib (tick to lib) on your projects Library's tab.
The component should now appear in the designer as custom view.

Now i become this errors, by Compiling.

Please right click on the logs to copy the error and post it.
