Strecth Bitmap in ImageView

I have image colors, (161 * 96 = 15456).

I hold it in integer array, and i create a bitmap :

conf = Bitmap.Config.ARGB_8888;
bm = Bitmap.createBitmap(161, 96, conf);

I draw point by point on canvas and assign to bm (bitmap) :

canvas.drawPoint(i, j, paint);
canvas.setBitmap(bm);

Finally, i set the imageView :

imgPreview.setImageBitmap(bm);

It works perfectly, but my original imageView size 1200 * 900. So I want to stretch my bitmap. But i dont know, how can i do this because i draw point by point.

Are there any method to stretch bitmap in image view ?

I have : enter image description here

I want : enter image description here

You can use ScaleType programatically in a ImageView

imagePreview.setScaleType(ImageView.ScaleType.CENTER_CROP);

You can use the ImageView attribute android:scaleType. http://developer.android.com/reference/android/widget/ImageView.html#attr_android:scaleType

e.g. in your xml:

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

You can use the ImageView's setScaleType(...) method.

Use one of the FIT or CENTER_CROP parameters from ImageView.ScaleType depending on your needs.

EDIT: Probably you want FIT_CENTER
