在Android Studio的布局管理器上展开图像

Question

I have picture like this, ImageView size is the same as the image size with wrap_content option .

 <ImageView
            android:id="@+id/imageView"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            app:srcCompat="@drawable/backnormal" />

Then I drag the edge of the imageView , only imageView is expanded and wrap_content is changed automatically like ( wrap_content -> 300dp )

I would like to expand the image itself and not only imageView . Is it possible??

You can use android:scaleType="centerCrop" attribute. There are also other values for this attribute.
