Please use below trick    Create an image button with your icon and set its background color to be transparent  Put the image button on the EditText  Implement the  onclic k listener of the button to execute your function

You don t have access to the right image as far my knowledge  unless you override the onTouch event  I suggest to use a RelativeLayout  with one editText and one imageView  and set OnClickListener over the image view as below    lt RelativeLayout         android id    id rlSearch          android layout width  wrap content          android layout height  wrap content          android background   android drawable edit text          android padding  5dip   gt            lt EditText             android id    id txtSearch              android layout width  match parent               android layout height  wrap content              android layout centerVertical  true              android layout toLeftOf    id imgSearch              android background   00000000              android ems  10   gt            lt ImageView             android id    id imgSearch              android layout width  wrap content              android layout height  wrap content              android layout alignParentRight  true              android layout centerVertical  true              android src   drawable btnsearch    gt       lt  RelativeLayout gt

This has been already answered but I tried a different way to make it simpler   The idea is using putting an ImageButton on the right of EditText and having negative margin to it so that the EditText flows into the ImageButton making it look like the Button is in the EditText           lt LinearLayout         android layout width  match parent          android layout height  wrap content          android orientation  horizontal  gt           lt EditText             android id    id editText              android layout weight  1              android layout width  0dp              android layout height  wrap content              android hint  Enter Pin              android singleLine  true              android textSize  25sp              android paddingRight  60dp                gt           lt ImageButton             android id    id pastePin              android layout marginLeft  -60dp              style   android buttonBarButtonStyle              android paddingBottom  5dp              android src   drawable ic action paste              android layout width  wrap content              android layout height  wrap content    gt       lt  LinearLayout gt    Also  as shown above  you can use a paddingRight of similar width in the EditText if you don t want the text in it to be flown over the ImageButton   I guessed margin size with the help of android-studio s layout designer and it looks similar across all screen sizes  Or else you can calculate the width of the ImageButton and set the margin programatically

I know this is quite old  but I recently had to do something very similar  and came up with a much simpler solution   It boils down to the following steps    Create an XML layout that contains the EditText and Image Subclass FrameLayout and inflate the XML layout Add code for the click listener and any other behavior you want    without having to worry about positions of the click or any other messy code    See this post for the full example  Handling click events on a drawable within an EditText

Simple Solution  use methods that Android has already given  rather than reinventing wheeeeeeeeeel  -   editComment setOnTouchListener new OnTouchListener              Override         public boolean onTouch View v  MotionEvent event                final int DRAWABLE LEFT   0              final int DRAWABLE TOP   1              final int DRAWABLE RIGHT   2              final int DRAWABLE BOTTOM   3               if event getAction      MotionEvent ACTION UP                    if event getRawX    gt    editComment getRight   - editComment getCompoundDrawables   DRAWABLE RIGHT  getBounds   width                              your action here                   return true                                              return false
