try this

InputStream istream =   null;
try {
     istream = this.getContentResolver().openInputStream(yourBitmapUri);
} catch (FileNotFoundException e1) {
     e1.printStackTrace();
}

BitmapRegionDecoder decoder     =   null;
try {
    decoder = BitmapRegionDecoder.newInstance(istream, false);
} catch (IOException e) {
    e.printStackTrace();
}
Bitmap bMap = decoder.decodeRegion(new Rect(istream, x to start from, y to start from, x to end with, y to end with), null);    
imageView.setImageBitmap(bMap);
