基于Goolgle最新NavigationDrawer实现全屏水平平移

常见实现App 上面侧边栏菜单之前使用SlidingDrawer，现在发现Goolgle原生NavigationDrawer也挺好用。但是细心的开发者们发现NavigationDrawer没有类似SlidingDrawer全屏平移的效果，其实不用着急，简单修改即可实现此效果。

话不多说上代码：

    //.....省略部分代码    private DrawerLayout.SimpleDrawerListener simpleDrawerListener;//侧边栏基础布局DrawerLayout    private NavigationView navigationView;//侧边栏控件    private View contentView;//主体内容布局        //.....省略部分代码    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_navigation_drawer);        //.....省略部分代码        drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);        contentView = findViewById(R.id.content);        //.....省略部分代码        simpleDrawerListener  = new DrawerLayout.SimpleDrawerListener() {            @Override            public void onDrawerSlide(View drawerView, float slideOffset) {                super.onDrawerSlide(drawerView, slideOffset);                System.out.println(navigationView.getWidth()+navigationView.getX());                //根据侧边栏控件宽度和其移动像素计算内容布局位移，使内容布局左边紧贴侧边栏控件右边                contentView.setX(navigationView.getWidth()+navigationView.getX());            }            @Override            public void onDrawerOpened(View drawerView) {                super.onDrawerOpened(drawerView);                System.out.println("+++++++++++onDrawerOpened++++++++++++");            }            @Override            public void onDrawerClosed(View drawerView) {                super.onDrawerClosed(drawerView);                System.out.println("+++++++++onDrawerClosed++++++++++++++");            }            @Override            public void onDrawerStateChanged(int newState) {                super.onDrawerStateChanged(newState);                System.out.println("+++++++++onDrawerStateChanged++++++++++++++"+newState);            }        };        drawerLayout.addDrawerListener(simpleDrawerListener);        //.....省略部分代码    }

代码就不发了，本实例在AndroidStudio新建Navigation Drawer Activity自动生成Demo上修改，不太懂需要demo的可以留言。看，实际上Google工程师已经把路铺好，剩下的就是广大的程序员去发挥想象力了。
