Android实现通过字符串找到图片、Class

1、通过字符串找到相应图片并展示

 ApplicationInfo appInfo = getActivity().getApplicationInfo();
 int resID = getResources().getIdentifier("图片名字", "mipmap", appInfo.packageName);
 holder.setImageResource(R.id.title_img, resID);

2、通过字符串找到Class并跳转

   Class<?> aClass = null;
   try {
   
       aClass = Class.forName("相应的class包名+xxx.class");
       Intent intent = new Intent(getActivity(), aClass);
       startActivity(intent);
   } catch (Exception e) {
   
       e.printStackTrace();
   }
