Android：单击按钮放大ImageView的特定部分

Question

I have an ImageView with a bunch of Buttons underneath the image. I want to be able to zoom on a particular part of that ImageView depending on which of the buttons I press! I'm new to Android Development so any help on this will be very much appreciated.

Cheers!

Answer 1

ImageView is a complete view, either you operate on it completely or do nothing on it. In my opinion what you can do is slice the images into 'n^2' parts and display them as a grid of nXn and when the user presses a button to increase the grid size then slice it into (n+1)^2 and then a grid of (n+1)*(n+1) and so on.

EDIT:

Lets have a root RelativeLayout and then we will have multiple imageviews in that something like below

<RelativeLayout
   .....
   .....>
   <ImageView android:id="@+id/kitchen"
     .....
     .....
   />
   <ImageView android:id="@+id/bedroom"
     android:layout_toRightOf="@id/kitchen"
     .....
     .....
   />
   .....
   .....
   </RelativeLayout>
