Dynamically fill the predefined Relative layout

so i have an relative layout which looks like this..

Click for screenshot

and it's code is:

<RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="150dp"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true">

        <ImageView
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:id="@+id/imageView"
            android:layout_alignParentTop="true"
            android:layout_centerHorizontal="true"
            android:src="@drawable/image"
            android:scaleType="fitXY" />

        <Button
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="New Button"
            android:id="@+id/button"
            android:layout_alignParentBottom="true"
            android:layout_centerHorizontal="true"
            android:background="#60000000"
            android:textSize="30dp"
            android:textAlignment="textEnd"
            android:textColor="#ffffff" />

    </RelativeLayout>

I've got two things to do firstly use this relative layout again and again dynamically and fill the imageview and textview with different content.

Secondly I want to arrange the Relativelayout dynamically one after another like this.

Use RecyclerView for that

you Can learn them from

http://developer.android.com/reference/android/support/v7/widget/RecyclerView.html

and

Best practice is using RecyclerView for this kind of need. But still you should achieve this by inflating and adding this layout to parent layout.

Imagine you have a model that contains background and text

public class Item {
    private String text;
    private int background;

    public Item (String text_, int background_) {
        this.text = text_;
        this.background = background_;
    }

    public String getText() { return this.text; }

    public int getBackground() { return this.background; }
}

Let's say you have an ArrayList<Item> of this object. And you have a parent linear layout.

LinearLayout parentLayout = (LinearLayout)findViewById(R.id.parent_layout);
for (Item item: items) {
        View view = getLayoutInflater(null).inflate(R.layout.your_button_layout,  parentLayout, false);
        TextView text= (TextView) view.findViewById(R.id.text);
        ImageView background= (ImageView) view.findViewById(R.id.image);
        text.setText(item.getText());
        background.setBackground(item.getBackground());

        parentLayout.addView(view);
    }

You can apply margin & padding attributes to your child layout to have similar look like RecyclerView
