How to get screen width and height

Question

I tried to use following code to get screen width and height in android app development:

Display display = getWindowManager().getDefaultDisplay(); 
int scree         


        

Answer 1

Display display = getActivity().getWindowManager().getDefaultDisplay(); 
int screenWidth = display.getWidth();
int screenHeight = display.getHeight();
Log.d("Tag", "Getting Width >> " + screenWidth);
Log.d("Tag", "Getting Height >> " + screenHeight);

This worked properly in my application

Answer 2

DisplayMetrics metrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(metrics);

int height = metrics.heightPixels;
int width = metrics.widthPixels;

i guess the code which you wrote is deprecated.

Answer 3

Alternative way using function

private int[] getScreenSIze(){
        DisplayMetrics displaymetrics = new DisplayMetrics();
        getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
        int h = displaymetrics.heightPixels;
        int w = displaymetrics.widthPixels;

        int[] size={w,h};
        return size;

    }

on button click or on your create function add the following code

int[] screenSize= getScreenSIze();
        int width=screenSize[0];
        int height=screenSize[1];
        screenSizes.setText("Phone Screen sizes \n\n  width = "+width+" \n Height = "+height);

See demo source code

Answer 4

WindowManager w = getWindowManager();
Display d = w.getDefaultDisplay();
DisplayMetrics metrics = new DisplayMetrics();
d.getMetrics(metrics);

Log.d("WIDTH: ", String.valueOf(d.getWidth()));
Log.d("HEIGHT: ", String.valueOf(d.getHeight()));

Answer 5

    int scrWidth  = getWindowManager().getDefaultDisplay().getWidth();
    int scrHeight = getWindowManager().getDefaultDisplay().getHeight();

Answer 6

       /*
        *DisplayMetrics: A structure describing general information about a display, such as its size, density, and font scaling.
        * */

 DisplayMetrics metrics = getResources().getDisplayMetrics();

       int DeviceTotalWidth = metrics.widthPixels;
       int DeviceTotalHeight = metrics.heightPixels;
