Answer 1

所有你需要做的是：

1. 渲染矢量在ImageView的
2. 从ImageView的
获取位图
3. 将位图保存为PNG文件

渲染矢量在ImageView的：

//-------------------------------------------------------------------------------- 
    Bitmap bitmap = ((BitmapDrawable)image.getDrawable()).getBitmap();//get Bitmap 
    SaveImage(bitmap,"my_png_file");//save it 
//-------------------------------------------------------------------------------- 

保存位图的PNG文件：

//-------------------------------------------------------------------------------- 
    private void SaveImage(Bitmap finalBitmap, String filename) 
    { 
      String root = Environment.getExternalStorageDirectory().toString(); 
      File myDir = new File(root + "/saved_images"); 
      myDir.mkdirs(); 
      Random generator = new Random(); 
      int n = 10000; 
      n = generator.nextInt(n); 

      String fname = filename +".png"; 
      File file = new File (myDir, fname); 
      if (file.exists()) file.delete(); 
      try { 
       FileOutputStream out = new FileOutputStream(file); 
       finalBitmap.compress(Bitmap.CompressFormat.PNG, 100, out); 
       out.flush(); 
       out.close(); 
       sendBroadcast(new Intent(
        Intent.ACTION_MEDIA_MOUNTED, 
        Uri.parse("file://" + Environment.getExternalStorageDirectory()))); 

      } catch (Exception e) { 
       e.printStackTrace(); 
      } 
    }//SaveImage 
    //--------------------------------------------------------------------------------
