Android-linear layout arrangement varies in emulator and device

Question

I am developing project with 26 cards design alphabets in linear layout fashion in android. I had included android:adjustViewBounds="true" and android:scaleType="centercrop". Forunately it works well in emulator and does not show up in the real device. What would be the issue to make it work as well in device? Could you assist me regarding this? Below is the piece of code working in emulator not in device.

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_height="fill_parent"
