Android - Stack XML Layouts ontop of each other

Question

My name is Cooper. Fairly new to java (a month into it or so)

If you where to look at instagram, they have images stacked on images, with comments, ect.

Looks like a XML layout is just copied and pasted on top of each other.

Is that what they are doing? How can I do that?

FrameLayout & RelativeLayout let you stack Views above each other, the z index is by the order they are added in code or written in xml. A layout is basically an extension of ViewGroup with rules, If you want to include another layout in a layout look into <include> and <merge> tags: http://developer.android.com/training/improving-layouts/reusing-layouts.html

Now how could I have for example: Layout 1 Include Layout 1 programatically? – Cooper Scott Jul 29 '15 at 00:23
Any Layout can be inflated with View.inflate and check this question about adding the new View to a FrameLayout for example: http://stackoverflow.com/a/8931551/348378 – Raanan Jul 29 '15 at 07:10

Here is an example using a FrameLayout and some TextViews. All the views' inside this FrameLayout will appear at the (0,0) coordinate but have an offset found in the dimension of the childs individual view's android:layout_marginLeft/android:layout_marginStart and android:layout_marginTop attributes

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content">

    <TextView
        android:text="11111111"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="6dp"
        android:layout_marginTop="6dp"
        android:layout_marginStart="6dp" />


    <TextView
        android:text="2222222"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="12dp"
        android:layout_marginTop="12dp"
        android:layout_marginStart="12dp" />

    <TextView
        android:text="3333333"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="18dp"
        android:layout_marginTop="18dp"
        android:layout_marginStart="18dp" />

</FrameLayout>

And what it looks like:
