在项目中有各种各样的需求，我今天就遇到一个这种需求侧滑菜单
当我们在应用NavigationView+DrawerLayout的时
点击完Menu Drawer进行关闭的同时activity也在打开我发现这样做效果不是很好有掉帧的情况出现卡顿
感谢胡凯的图
开始我以为是activity create里面操作延迟比较久后来注释所有的方法后发现有一点卵用但是还是有延迟
仔细看图就会发现当drawer回收一半activity就出来了所以我考虑将选中事件的操作放到drawer close 之后进行下面是之前的操作选中后关闭跳转

    /*记录点击那个按钮*/
    public int flag;
    NavigationView.OnNavigationItemSelectedListener navListener = new NavigationView.OnNavigationItemSelectedListener() {
        @Override
        public boolean onNavigationItemSelected(MenuItem item) {
            //关闭drawer
            if (drawer.isDrawerOpen(GravityCompat.START)) {
                drawer.closeDrawers();
            }
            int id = item.getItemId();
            switch (id) {
                case R.id.nav_advanced:
                    flag = id;
                    break;
                case R.id.nav_appmanager:
                    flag = id;
                    break;
                case R.id.nav_photo:
                    flag = id;
                    myStartActivity(CleanActivityNew.this,PhotoCleanActivity.class);
                    break;
                case R.id.nav_noti:
                    flag = id;
                    break;
                case R.id.nav_cpu:
                    flag = id;
                    break;
                case R.id.nav_device:
                    flag = id;
                    break;
                case R.id.nav_lock:
                    flag = id;
                    break;
            }
//            DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
            return true;
        }
    };

现在的操作是给drawerlayout 设置监听事件 close 之后执行操作上代码

  /*记录点击那个按钮 以便于在 drawerlayout close 中区分点击位置*/
    public int flag;
    NavigationView.OnNavigationItemSelectedListener navListener = new NavigationView.OnNavigationItemSelectedListener() {
        @Override
        public boolean onNavigationItemSelected(MenuItem item) {
            //关闭drawer
            if (drawer.isDrawerOpen(GravityCompat.START)) {
                drawer.closeDrawers();
            }
            int id = item.getItemId();
            switch (id) {
                case R.id.nav_advanced:
                    flag = id;
                    break;
                case R.id.nav_appmanager:
                    flag = id;
                    break;
                case R.id.nav_photo:
                    flag = id;
                    break;
                case R.id.nav_noti:
                    flag = id;
                    break;
                case R.id.nav_cpu:
                    flag = id;
                    break;
                case R.id.nav_device:
                    flag = id;
                    break;
                case R.id.nav_lock:
                    flag = id;
                    break;
            }
//            DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
            return true;
        }
    };

在NavigationView设置完监听之后给DrawaerLayout 设置事件

 navigationView.setNavigationItemSelectedListener(navListener);//绑定menu的点击事件
        drawer.addDrawerListener(new DrawerLayout.DrawerListener() {
            @Override
            public void onDrawerSlide(View drawerView, float slideOffset) {

            }

            @Override
            public void onDrawerOpened(View drawerView) {

            }

            @Override
            public void onDrawerClosed(View drawerView) {
                switch (flag) {
                    case R.id.nav_advanced:

//逻辑操作                        myStartActivity(CleanActivityNew.this,DepthcleanupActivity.class);

                        break;
            }

            @Override
            public void onDrawerStateChanged(int newState) {

            }
        });
