Android - LinearLayout Horizontal with wrapping children

As of May 2016 Google has created its own FlexBoxLayout which should solve your problem.

You can find the GitHub repo here: https://github.com/google/flexbox-layout

This should be what you want:

import android.content.Context;
import android.util.AttributeSet;
import android.view.View;
import android.view.ViewGroup;
