**下面是android上获取截图的办法

FileInputStream graphics = null;
                try {
                        graphics = new FileInputStream(“/dev/graphics/fb0”);
                } catch (FileNotFoundException e) {
                        e.printStackTrace();
                        return null;
                }
    
                DataInputStream dStream = new DataInputStream(graphics);
                dStream.readFully(piex);
                dStream.close();
    
                int[] colors = new int[screenHeight * screenWidth];
                // 将rgb转为色值
                for (int m = 0; m < colors.length; m++) {
                        int r = (piex[m * 4] & 0xFF);
                        int g = (piex[m * 4 + 1] & 0xFF);
                        int b = (piex[m * 4 + 2] & 0xFF);
                        int a = (piex[m * 4 + 3] & 0xFF);
                        colors[m] = (a << 24) + (r << 16) + (g << 8) + b;
                }
    
                Bitmap bitmap = Bitmap.createBitmap(colors, screenWidth, screenHeight,
                                Bitmap.Config.ARGB_8888);
