Here is another way
public static String appendImages(ArrayList<Bitmap> bitmaplist) {
//assume bitmaplist has atleast 1 bitmap
Bitmap tmpbitmap = bitmaplist.get(0);
int w = tmpbitmap.getWidth();
int h = tmpbitmap.getHeight();
Bitmap new_image = Bitmap.createBitmap(w, h * bitmaplist.size(),
tmpbitmap.getConfig());
int[] pixels = new int[w * (h * bitmaplist.size())];
int j = 0;
for (Bitmap uri : bitmaplist) {
Bitmap mBitmap = uri;
mBitmap.getPixels(pixels, j * h * w, w, 0, 0, w, h);
j++;
}
new_image.setPixels(pixels, 0, w, 0, 0, w, h * bitmaplist.size());
String filepath = "/sdcard.jpg";
File imagefile = new File(filepath);
try {
FileOutputStream fos = new FileOutputStream(imagefile);
new_image.compress(CompressFormat.JPEG, 100, fos);
fos.flush();
fos.close();
}
catch (Exception e) {
Log.e("Error in File append", e.getMessage());
}
return filepath;
}
