To adjust the size of an Android ImageView, you can use the following methods:

  1. By using layout parameters, you can set the size of an ImageView in the layout file using the attributes layout_width and layout_height. For example, you can set the layout parameters to a fixed size or match_parent or wrap_content to fit the content or parent container.
<ImageView
    android:id="@+id/imageView"
    android:layout_width="100dp"
    android:layout_height="100dp"
    android:src="@drawable/image"
    />
  1. By using the setScaleType attribute, you can adjust the size and position of the image displayed in the ImageView. For example, you can use fitXY to stretch the image to fill the entire ImageView.
<ImageView
    android:id="@+id/imageView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:src="@drawable/image"
    android:scaleType="fitXY"
    />
  1. Dynamically setting size using code: In Java, you can use the setLayoutParams method to dynamically adjust the size of an ImageView. For example, you can create a LayoutParams object, set the width and height, and then apply it to the ImageView.
ImageView imageView = findViewById(R.id.imageView);
LayoutParams params = new LayoutParams(100, 100);
imageView.setLayoutParams(params);

By using the above methods, the size of an Android ImageView can be easily adjusted.
