Calculate Android screen size

I have this piece of code :

    Point point = new Point();
    getWindowManager().getDefaultDisplay().getSize(point);
    setScreenSize(point);

This returns the total height of the display in pixels. However, this includes the notification bar and, on some devices, the bottom bar that contains the android-specific buttons (back, home and that other one).

My question is a two-parter.

How can I find out the height of the notification bar? How can I find if the device has those buttons on the screen, and if it does, what is the height of that bar?

You can try these.I recently used below code in one of my projects. It works 

Display display = getWindowManager().getDefaultDisplay();
String displayName = display.getName();  // minSdkVersion=17+
Log.i(TAG, "displayName  = " + displayName);

// display size in pixels

Point size = new Point();
display.getSize(size);
int width = size.x;
int height = size.y;
Log.i(TAG, "width        = " + width);
Log.i(TAG, "height       = " + height);

// get in (pixels or dpi)

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

// this one is deprecated

int screenHeight = display.getHeight();
int screenWidth = display.getWidth();
Log.i(TAG, "screenHeight = " + screenHeight);
Log.i(TAG, "screenWidth  = " + screenWidth);

You can do this way:

Display mDisplay = getWindowManager().getDefaultDisplay();
Point mPoint = new Point();
mDisplay.getSize(mPoint);
int width = mPoint.x;
int height = mPoint.y;

Hope this will help you.

You can find a lot of the default Android specifications such as StatusBar (Metrics & Keylines) and NavBar (Structure) in the Android Material Design Specification...

I believe that status bar is 24dp and NavBar is 48dp as standard.

You can get the width and height in DP by using: 

DisplayMetrics displayMetrics = getActivity().getResources().getDisplayMetrics();

float screenWidthDP = displayMetrics.widthPixels / displayMetrics.density;
float screenHeightDP = displayMetrics.heightPixels / displayMetrics.density;
