Android实现合并生成分享图片功能

// 获取ScrollView 实际高度
 h = 0;
 for (int i = 0; i 

// BitmapFactory.decodeResource函数直接转换资源文件为Bitmap 

 Bitmap head = BitmapFactory.decodeResource(mContext.getResources(), R.drawable.share_term_table_header);
 Bitmap foot = BitmapFactory.decodeResource(mContext.getResources(), R.drawable.share_term_table_footer);

if (head == null) {
  return null;
 }
 int headWidth = head.getWidth();
 int kebianwidth = kebiao.getWidth();
 int fotwid = san.getWidth();

 int headHeight = head.getHeight();
 int kebiaoheight = kebiao.getHeight();
 int footerheight = san.getHeight();
 //生成三个图片合并大小的Bitmap
 Bitmap newbmp = Bitmap.createBitmap(kebianwidth, headHeight + kebiaoheight + footerheight, Bitmap.Config.ARGB_8888);
 Canvas cv = new Canvas(newbmp);
 cv.drawBitmap(head, 0, 0, null);// 在 0，0坐标开始画入headBitmap

 //因为手机不同图片的大小的可能小了 就绘制白色的界面填充剩下的界面
 if (headWidth
