title: Android TabLayout custom indicator width
body: <p>I want to reduce width of indicator - for example, make it's width not whole tab width, but 1/2 of tab width.<br>
  That's all I need to do, so I don't want to download some custom library and search where I can do this.</p>
  
  <p>Is it a way to do this or I should write such view by myself?</p>
