Answer 1

you should use the following attribute of the imageview to fit the image to the screen.

Controls how the image should be resized or moved to match the size of this ImageView.

Must be one of the following constant values.

Constant Value

matrix 0

fitXY 1

fitStart 2

fitCenter 3

fitEnd 4

center 5

centerCrop 6

centerInside 7

android:scaleType="fitxy"

like wise you can use others to change the size of your image.

Answer 2

You may consider having the image open in its own activity, with android:noHistory="true" in the manifest, and onClick() have it end the activity. That way you don't have to worry about the image resizing and ruining everything in the activity it is being chosen in.
