In my previous tutorial, I talked about the buton components. If you have not read it yet, I recommend you read it first.

RelativeLayout

    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
>


   <ImageView
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:layout_centerInParent="true"
       android:src="@mipmap/ic_launcher"

       android:id="@+id/button_id"

       /> </RelativeLayout>

Sometimes we need to show image in our application, in this case we can use imageview component. imageview component have a lot of attribute . For example, we set background image with android:src=”@mipmap/ic_launcher”  code, and setting the position on the page with android:layout_centerInParent=”true” code.  We can also define the color in the background , not just the picture.

when you will define the imageview component, do not forget setting the id, width and height attribute. We can this setting with the following code;

android:layout_width="wrap_content"        
android:layout_height="wrap_content"
android:id="@+id/button_id"
