Inflated tab items in Tab Layout does not match parent in android

Question

I have gone through these but does not seems to work

working with

android.support.design.widget.TabLayout

needs to set custom views to each child tab as a match parent to child size

• pragmatically give a size

      View v = LayoutInflater.from(this).inflate(R.layout.layout_two, null);
      v.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));
      tabLayout.getTabAt(0).setCustomView(v);
  

this works as a match parent because there is no background but once add a inflate view issue comes

 tabLayout.getTabAt(1).setText("About").setIcon(R.drawable.drop_complete);

• though about the tabIndicator as well setting its height to app:tabIndicatorHeight="0dp" or adding android:tabStripEnabled="false" does not help.

here is a picture with boundaries which clearly shows the small gap like padding(blue bar is my TabLayout with two tabs )

left one is inflated right one is normal .setIcon

any help to make inflated one match parent with no gaps ?

Here is my code

Answer 1

Set tabPaddingStart and tabPaddingEnd attributes. like this:

    <android.support.design.widget.TabLayout
            ...
            app:tabPaddingStart="0dp"
            app:tabPaddingEnd="0dp" >
