经过了多天的努力，终于把这该死的功能做出来了，同时也掉了太多坑了，不说这么多，直接上代码！！！！

public void unMount() {        try {            Log.v("DWXD", "issfvs");            StorageManager mSD = (StorageManager) mContext.getSystemService(Context.STORAGE_SERVICE);            List<Object> list = (List<Object>) StorageManager.class.getMethod("getVolumes").invoke(mSD);            Log.v("DWXD", "list" + list.toString());            for (int i = 0; i < list.size(); i++) {                Object volume = list.get(i);                if (volume != null) {                    String id = (String) Class.forName("android.os.storage.VolumeInfo").getMethod("getId").invoke(volume);                    Log.v("DWXD", "is " + id);                    int type = (int) Class.forName("android.os.storage.VolumeInfo").getMethod("getType").invoke(volume);                    Log.v("DWXD", "is " + type);                    // public                    if (type == 0) {                        StorageManager.class.getMethod("unmount", String.class).invoke(mSD, id);                    }                }            }        } catch (Exception e) {            e.printStackTrace();            Log.v("DWXD", e.getStackTrace().toString());        }    }    public void Mount() {        try {            Log.v("DWXD", "issfvs");            StorageManager mSD = (StorageManager) mContext.getSystemService(Context.STORAGE_SERVICE);            List<Object> list = (List<Object>) StorageManager.class.getMethod("getVolumes").invoke(mSD);            Log.v("DWXD", "list" + list.toString());            for (int i = 0; i < list.size(); i++) {                Object volume = list.get(i);                if (volume != null) {                    String id = (String) Class.forName("android.os.storage.VolumeInfo").getMethod("getId").invoke(volume);                    Log.v("DWXD", "is " + id);                    int type = (int) Class.forName("android.os.storage.VolumeInfo").getMethod("getType").invoke(volume);                    Log.v("DWXD", "is " + type);                    // public                    if (type == 0) {                        StorageManager.class.getMethod("mount", String.class).invoke(mSD, id);                    }                }            }        } catch (Exception e) {            e.printStackTrace();            Log.v("DWXD", e.getStackTrace().toString());        }    }}
