i hard code image by the following code.
<ImageView android:id="@+id/img" android:layout_width="60dp"
android:layout_height="60dp"
android:layout_centerVertical="true" />
Most simple way is
int h = 48; // height in pixels
int w = 48; // width in pixels
Bitmap scaled = Bitmap.createScaledBitmap(largeBitmap, h, w, true);
and detailed This is called the image scaling
