You can get the width and height of the screen and set one parameter for both layout_width and layout_height of button. How??

Display display=((WindowManager)getSystemService(Context.WINDOW_SERVICE)).
                                      getDefaultDisplay();
    int width=display.getWidth();
    int height=display.getHeight();

//Calculate width and height

Say For screen 240*320

buttonWidth=width/5;     result: buttonWidht=48;
 buttonHeight=height/10   result: buttonHeight=32;

Using LayoutParams object, set width and height to the button.

Now, if you run this code on device having screen size 320*480

 buttonWidth=width/5;     result: buttonWidht=64;
 buttonHeight=height/10   result: buttonHeight=48;

and so on for other devices too.

On that its showing "The method getSystemService(String) is undefined for the type LazyImageLoadAdapter" – user3407787 May 21 '14 at 12:00
in that you have to pass you activity context – Akash Moradiya May 21 '14 at 12:02
am a beginner, would u pls tell me how to do that? – user3407787 May 21 '14 at 12:07
just pass you application context to LazyImageLoadAdapter(context) – Akash Moradiya May 21 '14 at 12:08
then you can use that context at getSystemService(your activity context.WINDOW_SERVICE)) – Akash Moradiya May 21 '14 at 12:09

Try this.

        DisplayMetrics metrics = new DisplayMetrics();
        getWindowManager().getDefaultDisplay().getMetrics(metrics);
        int density = metrics.densityDpi;

        int width = 0, height = 0;
        metrics = new DisplayMetrics();        
         getWindowManager().getDefaultDisplay().getMetrics(metrics);

         //height is actual screen height
         height = metrics.heightPixels;     
         width = metrics.widthPixels;


         CustomAdapter mAdapter;
         //pass h to your adapter class and it will gives you the height as per you need
         h=height/3;
         mAdapter = new CustomAdapter(this,ImageArrayList1, ImageArrayList2,h);

is it possible to set the imageview heights 1/3 of screen size
