WindowManager wm = (WindowManager) this

.getSystemService(Context.WINDOW_SERVICE);

int width = wm.getDefaultDisplay().getWidth();

int height = wm.getDefaultDisplay().getHeight();

WindowManager wm1 = this.getWindowManager();

int width1 = wm1.getDefaultDisplay().getWidth();

int height1 = wm1.getDefaultDisplay().getHeight();

WindowManager manager = this.getWindowManager();

DisplayMetrics outMetrics = new DisplayMetrics();

manager.getDefaultDisplay().getMetrics(outMetrics);

int width2 = outMetrics.widthPixels;

int height2 = outMetrics.heightPixels;

Resources resources = this.getResources();

DisplayMetrics dm = resources.getDisplayMetrics();

float density1 = dm.density;

int width3 = dm.widthPixels;

int height3 = dm.heightPixels;
