How to scale the image loaded from sd card into image view?

Question

I want to scale image loaded from sd card into the image view .

Problem is whenever i load from sd card the image comes as full screen and i have set all the parameters fill_parent viewbounds scaletype etc. as per other questions.

What should be the way to do it ?

<ImageView
    android:id="@+id/imageView2"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignBottom="@+id/Frame"
    android:layout_alignLeft="@+id/Load1"
    android:adjustViewBounds="true"
    android:cropToPadding="true"
    android:scaleType="fitXY"
    android:src="@android:drawable/alert_light_frame" />

<ImageView
    android:id="@+id/imageView1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:layout_centerHorizontal="true"
    android:layout_marginBottom="14dp"
    android:scaleType="fitXY"
    android:src="@android:drawable/alert_light_frame" />

this is my image view code can u tell me what to change so that image comes according to the imageview size

Can you also add the code to how you're putting it into an `ImageView`? — tolgap, Aug 04 '12 at 23:10

Use fitCenter scaleType. In your layout definition, use the below attribute for your ImageViews

android:scaleType="fitCenter"

Can you post the full layout code? What are the dimensions (width/height) of the image? – Leonel Machava Aug 05 '12 at 12:55
actually image is dynamicaly loaded from the gallery so i dont kno what the dimensions of the image are . – Pallav Grover Aug 05 '12 at 13:22
Try loading a small image, eg. a 100x100 image. I suspect you are loading very big images that end up filling the whole screen. – Leonel Machava Aug 05 '12 at 13:35
but thats the point i want any image size to be fit in the image view – Pallav Grover Aug 05 '12 at 14:50

If the imageview is big and if you try to load a big image then the layout is doing what it is supposed to do.

So either give a fixed width/height to the ImageView instead of wrap_content or you have to scale the imagedown based on your Phones screen size.
