如何在ImageView中禁用图像拉伸？

Question

There are some ImageView and image for this view. ImageView is 100px/100px, but image is 50px/50px. I wouldn't like the image fills full space in ImageView, ie I want that the ImageView contains my image in center of ImageView without stretching. How can I do it?

UPDATE: Sorry, I've made a mistake. My ImageView is 50px/50px, and my image is 100px/100px. What do you think about it?

Answer 1

Add to your ImageView:

android:scaleType="center"

Note that in the Android Studio xml layout preview if you use the android:background="@drawable/my_image" you will still see your image streached (In run time it won't streach). But if you still want to see your ImageView background (not streached) also in the IDE preview use android:src="@drawable/my_image" instead of background property. (in any case the scaleType should be center)

Answer 2

You need to set the android:scaleType attribute on your image view. If the image is bigger than your view, either use centerInside or one of the fitXY , fitStart , fitEnd options.

You have all the info you need on the Android developer documentation for the ImageView class.

Answer 3

set the android:scaleType with proper value, you can give centerCrop .

eg android:scaleType="centerCrop"

Answer 4

In ImageView we have a property called scaleType that is shown below in the code.

 <ImageView
    android:id="@+id/imageView1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignLeft="@+id/button2"
    android:layout_alignParentTop="true"
    android:layout_marginLeft="16dp"
    android:layout_marginTop="94dp"

    android:scaleType="center"

    android:src="@drawable/ic_launcher" />

It will not scale your image.
