Java how to get width of window android

To get the width of the window in an Android app, you can use the getDefaultDisplay() method of the WindowManager class to get a Display object representing the default display, and then use the getSize() method of the Display class to get the size of the display in pixels.

Here's an example of how you can get the width of the window in an Android app:

import android.graphics.Point;
import android.view.Display;
import android.view.WindowManager;

// ...

WindowManager windowManager = getWindowManager();
Display display = windowManager.getDefaultDisplay();
Point size = new Point();
display.getSize(size);
int width = size.x;

In this example, the windowManager object is a WindowManager instance that provides access to the window manager, the display object represents the default display, and the size object is a Point instance that holds the width and height of the display in pixels. The width variable holds the width of the window.

You can also use the getMetrics() method of the Display class to get a DisplayMetrics object containing information about the display, such as the width and height in pixels.
