Scale Image in ImageView with Aspect Ratio

Introduction

When working with images in Android, it's common to need to scale an image to fit within an ImageView while maintaining its aspect ratio. This can be a bit tricky to accomplish, but with a few lines of code, it's possible to achieve a scaled image with the correct aspect ratio.

Solution

To scale an image with the correct aspect ratio in an ImageView, you can use the `setScaleType()` method to set the scale type of the ImageView to `CENTER_CROP`. This will ensure that the image is scaled to fill the ImageView while maintaining its aspect ratio.

Here's an example code snippet that demonstrates how to scale an image with the correct aspect ratio in an ImageView:

ImageView imageView = findViewById(R.id.my_image_view);
imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);

With this code, the image will be scaled to fill the ImageView while maintaining its aspect ratio. You can also adjust the size of the ImageView to control the size of the scaled image.

Conclusion

Scaling an image with the correct aspect ratio in an ImageView is a common task in Android development. By using the `setScaleType()` method with the `CENTER_CROP` scale type, you can achieve a scaled image with the correct aspect ratio.
