public static Bitmap getBitmapFromPath(String path){
    if (!new File(path).exists()) {
        return null;
    }
    //最大读取10M的图片
    byte[] buf = new byte[1024*1024*10];
    Bitmap bitmap = null;

    try {
        FileInputStream fis = new FileInputStream(path);
        int len = fis.read(buf, 0, buf.length);
        bitmap = BitmapFactory.decodeByteArray(buf, 0, len);
        if (bitmap == null) {
            return null;
        }
        fis.close();
    } catch (Exception e) {
        return null;
    }
    return bitmap;
