在Android中使用抽屉菜单创建基本活动

Question

我试图遵循这个答案，其主要思想是覆盖BaseActivity中的setContentView，该活动将由所有活动扩展，因此只有BaseActivity将具有导航抽屉。

然而，在我尝试实现答案后，我的导航从未显示（即使在BaseActivity）。我就是这么做的：

这是导航抽屉的xml：

<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <!-- Framelayout to display Fragments -->

    <FrameLayout
        android:id="@+id/frame_container"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

    <!-- Listview to display slider menu -->

    <ListView
        android:id="@+id/list_slidermenu"
        android:layout_width="120dp"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:background="@color/list_background"
        android:choiceMode="singleChoice"
        android:divider="@color/list_divider"
        android:dividerHeight="1dp"
        android:listSelector="@drawable/list_selector" />

</android.support.v4.widget.DrawerLayout>

这是我重写的setContentView（在BaseActive中）：

@Override
    public void setContentView(int layoutResID) {
        // TODO Auto-generated method stub
        mDrawerLayout= (DrawerLayout) getLayoutInflater().inflate(R.layout.activity_main, null); // Your base layout here
        actContent= (FrameLayout) mDrawerLayout.findViewById(R.id.frame_container);
        //listLayout = (LinearLayout) mDrawerLayout.findViewById(R.id.listLayout);
        getLayoutInflater().inflate(layoutResID, actContent, true);
        //getLayoutInflater().inflate(layoutResID, listLayout, true);
        super.setContentView(layoutResID);
    }

这是我在BaseActivity上的onCreate，注意我使用的是getLayoutInflater（）。充气而不是设置内容视图：

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        //setContentView(R.layout.activity_main);

        //getSupportActionBar().setDisplayShowHomeEnabled(false);
        //getSupportActionBar().setDisplayShowCustomEnabled(true);
        // enabling action bar app icon and behaving it as toggle button
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
        getSupportActionBar().setHomeButtonEnabled(true);

        mTitle = mDrawerTitle = getTitle();

        // load slide menu items
        navMenuTitles = getResources().getStringArray(R.array.nav_drawer_items);

        // nav drawer icons from resources
        navMenuIcons = getResources()
                .obtainTypedArray(R.array.nav_drawer_icons);

        //mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
        mDrawerLayout= (DrawerLayout) getLayoutInflater().inflate(R.layout.activity_main, null);
        //mDrawerList = (ListView) findViewById(R.id.list_slidermenu);
        mDrawerList = (ListView) mDrawerLayout.findViewById(R.id.list_slidermenu);

        navDrawerItems = new ArrayList<NavDrawerItem>();

        // adding nav drawer items to array
        // Home
        navDrawerItems.add(new NavDrawerItem(navMenuTitles[0], navMenuIcons.getResourceId(0, -1)));
        // Find People
        navDrawerItems.add(new NavDrawerItem(navMenuTitles[1], navMenuIcons.getResourceId(1, -1)));
        // Photos
        navDrawerItems.add(new NavDrawerItem(navMenuTitles[2], navMenuIcons.getResourceId(2, -1)));
        // Communities, Will add a counter here
        navDrawerItems.add(new NavDrawerItem(navMenuTitles[3], navMenuIcons.getResourceId(3, -1)));
        // Pages
        navDrawerItems.add(new NavDrawerItem(navMenuTitles[4], navMenuIcons.getResourceId(4, -1)));
        // What's hot, We  will add a counter here
        navDrawerItems.add(new NavDrawerItem(navMenuTitles[5], navMenuIcons.getResourceId(5, -1)));


        // Recycle the typed array
        navMenuIcons.recycle();

        mDrawerList.setOnItemClickListener(new SlideMenuClickListener());

        // setting the nav drawer list adapter
        adapter = new NavDrawerListAdapter(getApplicationContext(),
                navDrawerItems);
        mDrawerList.setAdapter(adapter);

        mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,
                R.drawable.ic_drawer, //nav menu toggle icon
                R.string.app_name, // nav drawer open - description for accessibility
                R.string.app_name // nav drawer close - description for accessibility
        ) {
            public void onDrawerClosed(View view) {
                getSupportActionBar().setTitle(mTitle);
                // calling onPrepareOptionsMenu() to show action bar icons
                invalidateOptionsMenu();
            }

            public void onDrawerOpened(View drawerView) {
                getSupportActionBar().setTitle(mDrawerTitle);
                // calling onPrepareOptionsMenu() to hide action bar icons
                invalidateOptionsMenu();
            }
        };
        mDrawerLayout.setDrawerListener(mDrawerToggle);

        if (savedInstanceState == null) {
            // on first time display view for first nav item
            displayView(0);
        }

    }

最后，我只需要像往常一样扩展BaseActivity类和代码。

更新

根据答案，这是我的工作覆盖setContentView：

@Override
    public void setContentView(final int layoutResID) {
        // TODO Auto-generated method stub
        mDrawerLayout= (DrawerLayout) getLayoutInflater().inflate(R.layout.activity_main, null); // Your base layout here
        actContent= (FrameLayout) mDrawerLayout.findViewById(R.id.frame_container);

        getLayoutInflater().inflate(layoutResID, actContent, true);
        super.setContentView(mDrawerLayout);

        mTitle = mDrawerTitle = getTitle();

        // load slide menu items
        navMenuTitles = getResources().getStringArray(R.array.nav_drawer_items);

        // nav drawer icons from resources
        navMenuIcons = getResources()
                .obtainTypedArray(R.array.nav_drawer_icons);

        mDrawerList = (ListView) mDrawerLayout.findViewById(R.id.list_slidermenu);

        navDrawerItems = new ArrayList<NavDrawerItem>();

        // adding nav drawer items to array
        // Home
        navDrawerItems.add(new NavDrawerItem(navMenuTitles[0], navMenuIcons.getResourceId(0, -1)));
        // Find People
        navDrawerItems.add(new NavDrawerItem(navMenuTitles[1], navMenuIcons.getResourceId(1, -1)));
        // Photos
        navDrawerItems.add(new NavDrawerItem(navMenuTitles[2], navMenuIcons.getResourceId(2, -1)));
        // Communities, Will add a counter here
        navDrawerItems.add(new NavDrawerItem(navMenuTitles[3], navMenuIcons.getResourceId(3, -1)));
        // Pages
        navDrawerItems.add(new NavDrawerItem(navMenuTitles[4], navMenuIcons.getResourceId(4, -1)));
        // What's hot, We  will add a counter here
        navDrawerItems.add(new NavDrawerItem(navMenuTitles[5], navMenuIcons.getResourceId(5, -1)));


        // Recycle the typed array
        navMenuIcons.recycle();

        mDrawerList.setOnItemClickListener(new SlideMenuClickListener());

        // setting the nav drawer list adapter
        adapter = new NavDrawerListAdapter(getApplicationContext(),
                navDrawerItems);
        mDrawerList.setAdapter(adapter);

        mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,
                R.drawable.ic_drawer, //nav menu toggle icon
                R.string.app_name, // nav drawer open - description for accessibility
                R.string.app_name // nav drawer close - description for accessibility
        ) {
            public void onDrawerClosed(View view) {
                getSupportActionBar().setTitle(mTitle);
                // calling onPrepareOptionsMenu() to show action bar icons
                invalidateOptionsMenu();
            }

            public void onDrawerOpened(View drawerView) {
                getSupportActionBar().setTitle(mDrawerTitle);
                // calling onPrepareOptionsMenu() to hide action bar icons
                invalidateOptionsMenu();
            }
        };
        mDrawerLayout.setDrawerListener(mDrawerToggle);

        //super.setContentView(mDrawerLayout);
        /*getLayoutInflater().inflate(layoutResID, actContent, true);
        super.setContentView(mDrawerLayout);*/
    }

Answer 1

我知道这已经得到了回答，但如果有人在为我的具体问题而挣扎：

DrawerLayout只能有两个孩子，content和navigationView。如果要包含工具栏，应将其包装在另一个布局内或抽屉布局外：

DrawerLayout
--LinearLayout (or any other layout)
----Toolbar
----Content
--NavigationView

或者：

LinearLayout (or any other layout)
--Toolbar
--DrawerLayout
----Content
----NavigationView

Answer 2

像这样更改您的setContentView（）。。。

@Override
public void setContentView(int layoutResID) {
    mDrawerLayout = (DrawerLayout) getLayoutInflater().inflate(R.layout.activity_main, null); 
    actContent = (FrameLayout) mDrawerLayout.findViewById(R.id.frame_container);
    // set the drawer layout as main content view of Activity.
    setContentView(mDrawerLayout);
    // add layout of BaseActivities inside framelayout.i.e. frame_container
    getLayoutInflater().inflate(layoutResID, actContent, true);
}
