</LinearLayout> 

this layout is fine in vertical orientation while when device orientatio changes to Horizontal the bottom buttons are invisible.I am following Salmans Ayub Answer For Image Zoomin and Out

Answer 1

I think You have design your layout in portrait mode(verticaly). Now either you have to bound it for portrait mode by adding this line android:screenOrientation="portrait" in your activity manifest,

OR

You have to design it for landscape mode by following this link- Android: alternate layout xml for landscape mode
