NavigationDrawer+Fragment实现侧滑菜单效果

学习了NavigationDrawer 官方Support包中的SlidingMenu版本，练了下手.用到了ListView中item不同的布局

以后会升级加上ViewPager和GridView实现多页面图片切换

代码：

	}

	@Override
	public View getView(LayoutInflater inflater, View convertView) {

		}
		TextView tv = (TextView) convertView.findViewById(R.id.list_content);

		return convertView;
	}

	@Override
