导航抽屉，并与Android的活动 [英] Navigation Drawer and with Activity in Android

问题描述

我想出来的导航抽屉（滑轨菜单）中的http://www.androidhive.info/2013/11/android-sliding-menu-using-navigation-drawer/

I am trying out the navigation drawer (slide menu) given in http://www.androidhive.info/2013/11/android-sliding-menu-using-navigation-drawer/

通过以​​上链接的差异和我是不是调用片段，我试图调用活动。当应用程序打开，我无法看到导航抽屉菜单我只能看到与HOME活动的操作栏打开。

The difference with above link and mine is that instead of calling fragments I am trying to call the activity. When the app opens I am not able to see the Navigation drawer menu I can see only the action bar with HOME activity opened.

下面是我改变了code：（？是不是需要有一个片段或我可以使用活动我的抽屉式导航第一屏）

Here is the code that I changed: (Is it necessary to have a fragment or can I use activity for my first screen in Navigation Drawer?)

    mTitle = mDrawerTitle = getTitle();

    navMenuTitles = getResources().getStringArray(R.array.nav_drawer_items);
    navMenuIcons = getResources().obtainTypedArray(R.array.nav_drawer_icons);
    mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
    mDrawerList = (ListView) findViewById(R.id.left_drawer);    

    navDrawerItems = new ArrayList<NavDrawerItem>();

    navDrawerItems.add(new NavDrawerItem(navMenuTitles[0], navMenuIcons.getResourceId(1, -1)));
    navDrawerItems.add(new NavDrawerItem(navMenuTitles[1], navMenuIcons.getResourceId(2, -1),true, "200"));

    navMenuIcons.recycle();

    mDrawerList.setOnItemClickListener(new SlideMenuClickListener());

    adapter = new NavDrawerListAdapter(getApplicationContext(), navDrawerItems);
    mDrawerList.setAdapter(adapter);

    getActionBar().setDisplayHomeAsUpEnabled(true);
    getActionBar().setHomeButtonEnabled(true);

    mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,
            R.drawable.drawer,
            R.string.drawer_open,
            R.string.drawer_close
            ) 
    {
        public void onDrawerClosed(View view) 
        {
            getActionBar().setTitle(mTitle);
            invalidateOptionsMenu();
        }

        public void onDrawerOpened(View drawerView) 
        {
            getActionBar().setTitle(mDrawerTitle);
            invalidateOptionsMenu();
        }
    };
    mDrawerLayout.setDrawerListener(mDrawerToggle);

    if (savedInstanceState == null) 
    {
        displayView(0);
    }
}

private class SlideMenuClickListener implements
ListView.OnItemClickListener
{
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) 
    {
        displayView(position);
    }
}
private void displayView(int position) 
{
    switch (position) 
    {
    case 0:
        //fragment = new HomeFragment();        

        Intent intent = new Intent(this, Home.class);
        startActivity(intent);

        return;

    case 1:
        //fragment = new FindPeopleFragment();

        Intent intent1 = new Intent(this, Profile.class);
        startActivity(intent1);
        break;

    case 2:
        //fragment = new PhotosFragment();

        Intent intent2 = new Intent(this, Details.class);
        startActivity(intent2);
        break;

    default:
        break;
    }

    mDrawerList.setItemChecked(position, true);
    mDrawerList.setSelection(position);
    setTitle(navMenuTitles[position]);
    mDrawerLayout.closeDrawer(mDrawerList);
}

我要如何解决这个问题，以显示导航抽屉在我家的活动？

How do I fix this to show Navigation drawer on my Home Activity?

更新：

我甚至尝试在这个环节给出以下选项：

I even tried the following option given in this link:

How can I call one of my activity using navigation drawer ? but I am still not getting the navigation slide menu.

推荐答案

可以这样做... 导航抽屉是从活动的布局，你不能显示在另一个活动的一个活动，你需要使用一个片段为这个！

You can't do that... Navigation drawer is a layout from an activity and you cant show an activity inside another activity, you need to use a fragments for this!

这是活动是一个屏幕，则不能显示在另一个屏幕的屏幕，而是一个片段可以是一个画面的组成部分，并且可以膨胀的片段的活性的一个容器内，然后显示给用户。

An activity is a screen, you cant show a screen inside another screen, but a fragment may be a component of a screen, and you can inflate a fragment inside a container of an activity and then show to the user.

如果你wan't做到这一点，你可以创建一个抽象的活动和继承，但你不会有一个片段AA活动，您将有每一个多种活动与自己的抽屉式导航。

if you wan't do this, you can create a abstract activity and inherit, but you will not have a a activity in a fragment, you will have a multiple activities with each one with your own navigation drawer.
