//得到application对象ApplicationInfo appInfo = getApplicationInfo();//得到该图片的id(name 是该图片的名字，"drawable" 是该图片存放的目录，appInfo.packageName是应用程序的包)int resID = getResources().getIdentifier(name, "drawable", appInfo.packageName);//代码如下public Bitmap getRes(String name) {ApplicationInfo appInfo = getApplicationInfo();int resID = getResources().getIdentifier(name, "drawable", appInfo.packageName);return BitmapFactory.decodeResource(getResources(), resID);}

String path = "com/xiangmu/test.png"; //图片存放的路径InputStream is = getClassLoader().getResourceAsStream(path); //得到图片流
