Android Tab Layout not taking up full width with custom view

Question

Android TabLayout tabPaddingTop and tabPaddingBottom not being removed

Please refer to the above issue as well.

Even since i updated my design library to \"23.2.

Answer 1

I was stuck for hours until I found the method tab.setCustomView(idRes). Changing from inflated to this worked for me. Alernatively, if you are inflating you can use TabLayout.TabView as root viewgroup.

Apart from this, I am not sure if it is helpful but I used minWidth to the custom view layout.

This is what I wanted

Answer 2

In my case the problem was giving fixed height to the custom layout that i use for tabs. Using match_parent fixed my issue.

Answer 3

Just pass your tabLayout to this method and it's done!

private void setTabLayoutMatchParent(TabLayout tabLayout) {
    final ViewGroup tabLayoutChild = (ViewGroup)(tabLayout.getChildAt(0));
    int tabLen = tabLayoutChild.getChildCount();

    for (int j = 0; j < tabLen; j++) {
        View v = tabLayoutChild.getChildAt(j);
        v.setPadding(0, 0, 0, 0);
    }
}

Answer 4

Instead of dealing with TabLayout subviews, you can access TabLayout.Tab view directly and set the padding to 0 just like the code below.

for (int i = 0; i < tabLayout.getTabCount(); i++) {
    View tabView = tabLayout.getTabAt(i).view;
    tabView.setPadding(0, 0, 0, 0);
}

I'm doing this in the onCreateView callback and it works perfectly.

Answer 5

Try adding below attributes to TabLayout:

app:tabPaddingStart="-1dp"
app:tabPaddingEnd="-1dp"

Hope it'll work.

Answer 6

Setting different values or layout params did not work, so the only solution I got was to add the following, after you add the tabs to your tab layout,

final ViewGroup test = (ViewGroup)(tabs.getChildAt(0));//tabs is your Tablayout
int tabLen = test.getChildCount();

for (int i = 0; i < tabLen; i++) {
            View v = test.getChildAt(i);
            v.setPadding(0, 0, 0, 0);
        }
