Different tab width for TabLayout

Question

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.

Answer 1

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!

@digger's answer is working. However, if you want the tab which has an icon only wraps its content, you can set weight to 0 and width to LinearLayout.LayoutParams.WRAP_CONTENT. It worked for me.

fun TabLayout.setTabWidthAsWrapContent(tabPosition: Int) {
    val layout = (this.getChildAt(0) as LinearLayout).getChildAt(tabPosition) as LinearLayout
    val layoutParams = layout.layoutParams as LinearLayout.LayoutParams
    layoutParams.weight = 0f
    layoutParams.width = LinearLayout.LayoutParams.WRAP_CONTENT
    layout.layoutParams = layoutParams
}
