How To Get Image From Imageview In Android

In this article we will show you the solution of how to get image from imageview in android, the ImageView class is used in Android applications to display any type of image resource, whether it be an

Bitmap or an Drawable (it is a broad abstraction for anything that may be drawn on Android) (it is a general abstraction for anything that can be drawn in Android). Android.widget or the ImageView class.

The Kotlin subclass android.view.View is the class that ImageView inherits from. AnyClass.

ImageView can also be used to tint photos in order to reuse drawable resources and provide overlays for backdrop pictures. Additionally, an image's size and movement are managed using ImageView.

Step By Step Guide On How To Get Image From Imageview In Android :-

Usually, the built-in picture view is used to display images. In order to free you up to concentrate on app-specific issues like the style and content, this view handles the image's loading and optimization.

The ImageView takes care of the picture loading and scaling for you.

The scaleType parameter, which specifies how the photos will be scaled to fit in your layout, should be taken note of. Using scaleType "centre" in the example, the picture will be centred in the view and presented at its native resolution regardless of how much area the view takes up.

However, adjusting the width and height will change the aspect ratio, or the ratio between the width and height of the original image.

To maintain this aspect ratio, we can use the adjustViewBounds option. However, we must either let the height and/or width to be changeable (by using wrap content for the dimension and maxWidth for the width, for example). Otherwise, it is impossible to alter the dimensions to achieve the desired aspect ratio.

We can manage the image's general size and still make the necessary aspect ratio adjustments by combining these parameters.

In Java source code, we may also resize an ImageView at runtime by changing its width or height inside the view's getLayoutParams() method:

Given the wide range of screen sizes, resolutions, and densities available on Android devices, a robust system exists for matching the right image asset with the appropriate gadget.

Each device density category has its own drawable folder, including ldpi (low), mdpi (medium), hdpi (high), and xhdpi (extra high).

A folder for image drawables, such as drawable-mdpi, which stands for "medium dots per inch," can be found in every app.

<?xml version="1.0" encoding="utf-8"?>
app:srcCompat="@drawable/full_logo" />
app:srcCompat="@drawable/logo" />
import android.os.Bundle;
public class MainActivity extends AppCompatActivity {
protected void onCreate(Bundle savedInstanceState) {
