Changing TabLayout icons on left, top, right or bottom in com.android.support:design:23.1.0

I have exact solution which you guys want.

<android.support.design.widget.TabLayout
    android:id="@+id/tabLayout"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:tabInlineLabel="true"
    app:tabPaddingStart="@dimen/default_10dp">

Using below property you can achive desire result.

app:tabInlineLabel="true"

Thank you Atu for this good tip!

In my case, I have to add a linear layout to center tablayout title. I have also added some space characters to get margin between the icon and the text.

custom_tab.xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:gravity="center">
    <TextView
        android:id="@+id/tabContent"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:textAlignment="center"
        android:textColor="@android:color/white"
        android:gravity="center"/>
</LinearLayout>

Initialization code:

LinearLayout tabLinearLayout = (LinearLayout) LayoutInflater.from(this).inflate(R.layout.custom_tab, null);
TextView tabContent = (TextView) tabLinearLayout.findViewById(R.id.tabContent);
tabContent.setText("  "+getApplicationContext().getResources().getString(tabTitles[i]));
tabContent.setCompoundDrawablesWithIntrinsicBounds(tabIcons[i], 0, 0, 0);
mTabLayout.getTabAt(i).setCustomView(tabContent);

Actually, I have found a more elegant way (IMO) to do this without even using custom layouts, and just using the current default layout for tablayouts. Each tab layout item is in fact a Vertical LinearLayout, with the 1st item being an ImageView, and the 2nd item the TextView.

So the method consists of changing the tab's LinearLayout orientation to Horizontal. After that, the icon will be positioned on the left. Now, if you want to position it on the right, you can remove the ImageView (which is the 1st item) and add it to the LinearLayout, it will be added as the last element so positioned at the end of the TextView, but you will have to play around with the layout params in order to display it aligned and sized correctly.

So instead of re-adding the ImageView at the end of the LinearLayout, you can just add the drawable as a compound drawable to the TextView. add a little padding to it, and voila.

LinearLayout tabItemLayout = (LinearLayout)((LinearLayout)tabLayout.getChildAt(0)).getChildAt(tabIndex);
tabItemLayout.setOrientation(LinearLayout.HORIZONTAL);
ImageView iconView = (ImageView) tabItemLayout.getChildAt(0);
TextView textView = (TextView) tabItemLayout.getChildAt(1);
// remove the icon view
tabItemLayout.removeView(iconView);
// add the icon as compound drawable
textView.setCompoundDrawablesWithIntrinsicBounds(null, null, iconView.getDrawable(), null);
// set some padding
float DP = Resources.getSystem().getDisplayMetrics().density;
int padding = (int)(10 * DP);
textView.setCompoundDrawablePadding(padding);

With this method, we don't need a custom layout and don't need to inflate anything, we just re-use the existing views.
