Question

I have an ImageView.
I set it in xml as below:　

<ImageView
    android:id="@+id/background"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" />

And set image as below:

ImageView background
background.setImageBitmap(bitmap);

But if the ImageView’s parent layout narrow down, the IamgeView also narrow down.
And the image was resized.
I want to let it don’t resize.
Is it can modify by setScaleType?
Or how to do it?

Answer 1

Try setting adjustViewBounds parameter to true on the ImageView.

<ImageView
   android:id="@+id/background"
   android:layout_width="wrap_content"
   android:layout_height="wrap_content" 
   android:adjustViewBounds="true"/>
