截屏操作二:

    public static void screenView(View view,String fileName){
        Bitmap sCoverBitmap = Bitmap.createBitmap(
                view.getWidth(),view.getHeight(), Config.ARGB_8888);
        Canvas canvas = new Canvas(sCoverBitmap);
        view.draw(canvas);
        
        FileOutputStream fos = null;
        File dirFile = new File(StaticData.PATH);
        
        if(!dirFile.exists()){
            dirFile.mkdir();
        }
        
        try {
            File file = new File(StaticData.PATH,fileName);
            fos = new FileOutputStream(file);
            if (null != fos) {
                sCoverBitmap.compress(Bitmap.CompressFormat.PNG, 90, fos);
                fos.flush();
                fos.close();
            }
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
