Implement story reply like Instagram Android

Question

With Instagram when a user clicks on an EditText view the next scenario occurs:

• an emoji view is displayed [Not necessary in my case]
• story still maintains its width & height [Not being resized] [Required]
• keyboard is opened [Required]
• seems like view has a transparent background

For my case when I used ADJUST_RESIZE I got the view displayed properly but ImageView of story must have scaleType [fitXY or centerCrop] which has a bad UI with some images, if I did not make it with these scaleTypes ImageView will be resized and have margins beside it.

When not use ScaleTypes[fixtXY, centerCrop] while keyboard is opened:

while keyboard is closed:

Answer 1

The solution is to make ImageView with a fixed size.

private fun makeViewFullWidth(view: View) {
        val point = Point()
        // point will be populated with screen width and height 
        activity?.windowManager?.defaultDisplay?.getSize(point)
        val param = view.layoutParams
        param.width = point.x
        param.height = point.y
        view.layoutParams = param
    }
