Answer 1

使用android:src而不是app:srcCompat

Answer 2

You cloud use Following code for set Image

android:src

or

android:background

Hope it help

Answer 3

I think You should edit srcCompat to src. src is meant for source and sourceCompat Is for Backwards Compatiblity Of Vector Drawable Files For Android Devices Running On and below ICS -- IceCream Sandwich.

Answer 4

application extend AppCompatImageView. I Use

android:foreground

this work for me.

Answer 5

The bigger size of an image could be an issue as well. Resize the image to a smaller size (using paint in windows) and use it, this might work.
