保持导航抽屉打开 [英] Keep Navigation Drawer Open

问题描述

我正在构建一个应用程序，我想在导航抽屉中显示一些附加信息，但在导航抽屉内部单击后，默认情况下它会关闭，我希望它保持打开状态，直到用户单击导航抽屉外部或按下后退按钮

I'm building an app where I want to show some additional information in the navigation drawer but after clicking inside of the navigation drawer it closes by default and I would like it to remain open till the user click outside the navigation drawer or presses the back button

这可能吗?我该如何实施?如果不是，我如何在不使用导航视图的情况下实现它

Is this possible? And how do I implement it ? If not how else can I implement it without using the navigation view

我尝试过使用: mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_OPEN);在我的 onCreate 和 onNavigationItemSelected ...在 onCreate 上使用它默认打开导航抽屉让我无法关闭它

I have tried using: mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_OPEN); In my onCreate and onNavigationItemSelected ...Using it on the onCreate opens up the navigation drawer by default leaving me unable to close it

这是我的抽屉监听器代码；

This is my drawer listener code;

DrawerLayout   drawer = findViewById(R.id.drawer_layout);
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
    ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
            this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
    drawer.addDrawerListener(toggle);
    toggle.syncState();

推荐答案

    DrawerLayout drawerLayout; // Global variable

    drawerLayout = findViewById(R.id.drawer_layout);
    DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
        ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
                this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
        drawer.addDrawerListener(toggle);
        toggle.syncState();


        drawerLayout.openDrawer(GravityCompat.START); // Use this line of code where you want to keep open the drawerLayout.
