Question

How can I draw the custom drawable as attached in the image?

I don't the complete code, just steps how should I proceed would be sufficient and any links to advanced custom drawable tutorials. Thanks.

Answer 1

You can achieve this by using 9-patch images as background.

Here is a nice tool you can use online Simple Nine-patch Generator

Here is how you would achieve it

• Use a White background for your main layout view (Table View for example)
• create two 9-patch images for the grey boxes. One for the left side and other for the right side
• For the boxes that must be rendered grey use the appropriate 9-path background (left or right).
