I'm using TabLayout & ViewPager. I am trying to change the size of the Tab, like Whatsapp (camera icon). The size of the three Tabs is equal, but the Tab of the camera is smaller. In every attempt I make the size of the Tabs remains the same (equal across all tabs). Thanks.
You need to lower the weight of the LinearLayout of the corresponding tab.
LinearLayout layout = ((LinearLayout) ((LinearLayout) tabLayout.getChildAt(0)).getChildAt(YOUR_TAB_NUMBER));
LinearLayout.LayoutParams layoutParams = (LinearLayout.LayoutParams) layout.getLayoutParams();
layoutParams.weight = YOUR_WEIGHT; // e.g. 0.5f
layout.setLayoutParams(layoutParams);
Hope that helps!
