注意事项
主内容区的布局代码要放在侧滑菜单布局的前面,这可以帮助DrawerLayout判断谁是侧滑菜单，谁是主内容区
侧滑菜单的部分的布局（这里是ListView）可以设置layout_gravity属性，他表示侧滑菜单是在左边还是右边。
2.MainActivity.java 继承FragmentActivity
1).设置内容Fragment，设置状态栏
2).处理左侧点击事件,在点击事件中设置选中背景，关闭左边侧滑菜单。
public class MainActivity extends FragmentActivity{
private DrawerLayout mDrawerLayout;
private RelativeLayout rlHome, rlGift, rlShare;
private int currentSelectItem = R.id.rl_home;// 默认首页
