How to Dynamically Resize ImageViews in Android?

Dynamically Resizing ImageViews

In this digital realm, it's often crucial to adjust visual elements programmatically. Among them, ImageViews are widely used for displaying images in Android applications. If you find yourself needing to set the width and height of an ImageView dynamically, this article is the definitive guide for you.

To set the width of an ImageView, simply access the LayoutParams object associated with the ImageView and assign the desired width in pixels to the width property:

imageView.layoutParams.width = 100 // Set the width to 100 pixels

Similarly, to adjust the height, update the height property of the LayoutParams object:

imageView.layoutParams.height = 200 // Set the height to 200 pixels

Note: It's essential to call requestLayout() on the ImageView to ensure the new dimensions are applied correctly. This ensures that the ImageView redraws itself with the updated values.

imageView.requestLayout()

By embracing this approach, you gain the flexibility to control the size of your ImageViews at runtime, enabling dynamic UI adjustments and adaptive layouts.
