Try View treeobserver method.. Like :

   main_layout.getViewTreeObserver().addOnGlobalLayoutListener(
            new OnGlobalLayoutListener() {
                @Override
                public void onGlobalLayout() 
                    {

                        Rect r = new Rect();
                        // r will be populated with the coordinates of your view
                        // that area still visible.
                        main_layout.getWindowVisibleDisplayFrame(r);

                        int heightDiff = main_layout.getRootView().getHeight()-(r.bottom -r.top);

                    }
    });

Replace main_layout with your desired View's object. Hope it can help.

Hopefully this line of code will work for you. i use this when i want height n width of the screen

// get screen width/height

          DisplayMetrics metrics = new DisplayMetrics();
          getWindowManager().getDefaultDisplay().getMetrics(metrics); height =
          metrics.heightPixels; width = metrics.widthPixels;

myLayout.getHeight(); would return the actual visible height of the view only after it shows up on the screen before that it would only be 0. if you are really interested in knowing myLayout.getHeight() then you might wanna check after the view is displayed on the screen

If you want to know the height/width of the screen then you might consider using the following code : DisplayMetrics dm = new DisplayMetrics(); getWindowManager().getDefaultDisplay().getMetrics(dm);

final int height = dm.heightPixels; final int width = dm.widthPixels;

Give an id to your main layout element:

<LinearLayout id="myLayout">
    ...
</LinearLayout>

Then get its height after setContentView():

View myLayout = (View) findViewById(R.id.myLayout);
int height = myLayout.getHeight();
