问如何显示图像的一部分？

// Set some constants
private static final Bitmap SOURCE_BITMAP = BitmapFactory.decodeFile(....); // Get the source Bitmap using your favorite method :-)
private static final int START_X = 10;
private static final int START_Y = 15;
private static final int WIDTH_PX = 100;
private static final int HEIGHT_PX = 100;

// Crop bitmap
Bitmap newBitmap = Bitmap.createBitmap(SOURCE_BITMAP, START_X, START_Y, WIDTH_PX, HEIGHT_PX, null, false);

// Assign new bitmap to ImageView
ImageView image = (ImageView)findViewById(R.id.image_view);
image.setImageBitmap(newBitmap);
