Please use below class and pass the bitmap to this function and get return bitmap with Reflection effect.
public class NewReflection {
public static final Bitmap
applyReflection(Bitmap bitmap) {
// gap space
between original and reflected
final int reflectionGap =
4;
// get image
size
int width =
bitmap.getWidth();
int height =
bitmap.getHeight();
// this will
not scale but will flip on the Y axis
Matrix
matrix = new Matrix();
matrix.preScale(1,
-1);
// create a
Bitmap with the flip matrix applied to it.
// we only
want the bottom half of the image
Bitmap
reflectionImage = Bitmap.createBitmap(bitmap, 0, height / 2,
width,
height / 2, matrix, false);
// create a new
bitmap with same width but taller to fit reflection
Bitmap
bitmapWithReflection = Bitmap.createBitmap(width,
(height
+ height / 2), Config.ARGB_8888);
// create a
new Canvas with the bitmap that's big enough for
// the image
plus gap plus reflection
Canvas
canvas = new Canvas(bitmapWithReflection);
// draw in the
original image
canvas.drawBitmap(bitmap,
0, 0, null);
// draw in the
gap
Paint
defaultPaint = new Paint();
canvas.drawRect(0,
height, width, height + reflectionGap, defaultPaint);
// draw in the
reflection
canvas.drawBitmap(reflectionImage,
0, height + reflectionGap, null);
// create a
shader that is a linear gradient that covers the reflection
Paint
paint = new Paint();
LinearGradient
shader = new LinearGradient(0, bitmap.getHeight(), 0,
bitmapWithReflection.getHeight()
+ reflectionGap, 0x70ffffff,
0x00ffffff,
TileMode.CLAMP);
// set the
paint to use this shader (linear gradient)
paint.setShader(shader);
// set the
Transfer mode to be porter duff and destination in
paint.setXfermode(new
PorterDuffXfermode(Mode.DST_IN));
// draw a
rectangle using the paint with our linear gradient
canvas.drawRect(0,
height, width, bitmapWithReflection.getHeight()
+
reflectionGap, paint);
return
bitmapWithReflection;
