推荐答案

我通过用

            File file = new File(Environment.getExternalStorageDirectory()+"/filmfestival.png");
            try 
            {
                file.createNewFile();
                FileOutputStream ostream = new FileOutputStream(file);
                bitmap.compress(CompressFormat.PNG, 100, ostream);
                ostream.close();
            } 
            catch (Exception e) 
            {
                e.printStackTrace();
            }
