Why android resizes image?

I'm trying to change my application data source to the sdcard so that it doesn't take too much internal memory.

However, I had an I开发者_StackOverflowmage that was dynamically loaded from the resource and displayed in an ImageView, now I load the image from the sdcard whenever I need it.

I had been using imageBox.setImageResource(imageID) and I changed to imageBox.setImageDrawable(imageDrawable).

The problem is that now Android resizes my image and it doesn't fit where it should. Why is it resizing the image this way? And how can I stop it?

Thanks in advance :)

Add the tag android:scaleType="fitXY" to your ImageView's layout XML.

Ex.

<ImageView
 ... several settings ...
 android:scaleType="fitXY"/>

Edit:

If your image is simply too big to fit inside the ImageView - it will have to do some kind of scaling. There are some other options as described in the API:

http://developer.android.com/reference/android/widget/ImageView.ScaleType.html

Try the following for ImageView:

android:layout_height="fill_parent" 
android:layout_width="fill_parent"

No Scale Type.

The ImageView Should be within Fixed Size (in dp) Parent View.
