基于Goolgle最新NavigationDrawer实现全屏水平平移

Posted 2021-03-17 augustuss

常见实现App 上面侧边栏菜单之前使用SlidingMenu，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SlidingMenu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。
