一、橫向(兩個)
/**
* 橫向拼接
* <功能詳細描述>
* @param first
* @param second
* @return
*/
private Bitmap add2Bitmap(Bitmap first, Bitmap second) {
int width = first.getWidth() + second.getWidth();
int height = Math.max(first.getHeight(), second.getHeight());
Bitmap result = Bitmap.createBitmap(width, height, Config.ARGB_8888);
Canvas canvas = new Canvas(result);
canvas.drawBitmap(first, 0, 0, null);
canvas.drawBitmap(second, first.getWidth(), 0, null);
return result;
}
二、縱向(兩個)
/**
* 縱向拼接
* <功能詳細描述>
* @param first
* @param second
* @return
*/
private Bitmap addBitmap(Bitmap first, Bitmap second) {
int width = Math.max(first.getWidth(),second.getWidth());
int height = first.getHeight() + second.getHeight();
Bitmap result = Bitmap.createBitmap(width, height, Config.ARGB_8888);
Canvas canvas = new Canvas(result);
canvas.drawBitmap(first, 0, 0, null);
canvas.drawBitmap(second, 0, first.getHeight(),null);
return result;
}
三、縱向(多個)
/** * 將bitmap集合上下拼接 * * @return */ private Bitmap drawMulti(ArrayList<Bitmap> bitmaps) { int width = bitmaps.get(0).getWidth(); int height = bitmaps.get(0).getHeight(); for (int i = 1;i<bitmaps.size();i++) { if (width < bitmaps.get(i).getWidth()) { width = bitmaps.get(i).getWidth(); } height = height+bitmaps.get(i).getHeight(); } Bitmap result = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888); Canvas canvas = new Canvas(result); canvas.drawBitmap(bitmaps.get(0), 0, 0, paint); int h = 0; for (int j = 1;j<bitmaps.size();j++) { h = bitmaps.get(j).getHeight()+h; canvas.drawBitmap(bitmaps.get(j), 0,h, paint); } return result; }
