Answer 1

I would suggest you using FlexBoxLayout. It is similar to CSS's FlexBox and fits exactly your needs.

Just add deppendency to Gradle:

dependencies {
    compile 'com.google.android:flexbox:0.2.3'
}

Put the layout in .xml file:

<com.google.android.flexbox.FlexboxLayout/>

and add view's children dynamically:

flexBox.addView(child);
