问题描述

我试图按照这个的答案,主要思想是覆盖的setContentView BaseActivity ,将由所有活动延伸活动所以只有 BaseActivity 将有抽屉式导航。

不过,我的导航从未显示(甚至在 BaseActivity )后,我试图执行了答案。这是我做的:

这是抽屉式导航栏的XML:

 < android.support.v4.widget.DrawerLayout的xmlns:机器人=htt​​p://schemas.android.com/apk/res/android
    机器人:ID =@ + ID / drawer_layout
    机器人:layout_width =match_parent
    机器人:layout_height =match_parent>

    <! - 的FrameLayout显示片段 - >

    <的FrameLayout
        机器人:ID =@ + ID / frame_container
        机器人:layout_width =match_parent
        机器人:layout_height =match_parent/>

    <! - 列表视图显示滑块菜单 - >

    <的ListView
        机器人:ID =@ + ID / list_slidermenu
        机器人:layout_width =120dp
        机器人:layout_height =match_parent
        机器人:layout_gravity =开始
        机器人:背景=@色/ list_background
        机器人:choiceMode =singleChoice
        机器人:分隔=@色/ list_divider
        机器人:dividerHeight =1DP
        机器人:listSelector =@可绘制/ list_selector/>

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

这是我overrided 的setContentView (在 BaseActivity ):

  @覆盖
    公共无效的setContentView(INT layoutResID){
        // TODO自动生成方法存根
        mDrawerLayout =(DrawerLayout)getLayoutInflater()膨胀(R.layout.activity_main,空)。 //你的基地,这里布局
        actContent =(的FrameLayout)mDrawerLayout.findViewById(R.id.frame_container);
        // listLayout =(的LinearLayout)mDrawerLayout.findViewById(R.id.listLayout);
        。getLayoutInflater()膨胀(layoutResID,actContent,真正的);
        //getLayoutInflater().inflate(layoutResID,listLayout,真正的);
        super.setContentView(layoutResID);
    }
 

这是我的的onCreate BaseActivity ,请注意,我用 getLayoutInflater() .inflate 而不是的setContentView

  @覆盖
    保护无效的onCreate(包savedInstanceState){
        super.onCreate(savedInstanceState);
        //setContentView(R.layout.activity_main);

        //getSupportActionBar().setDisplayShowHomeEnabled(false);
        //getSupportActionBar().setDisplayShowCustomEnabled(true);
        //使操作栏中的应用程序图标,它表现为切换按钮
        getSupportActionBar()setDisplayHomeAsUpEnabled(真)。
        getSupportActionBar()setHomeButtonEnabled(真)。

        mTitle = mDrawerTitle =的getTitle();

        //负荷滑动菜单项
        navMenuTitles = getResources()getStringArray(R.array.nav_drawer_items)。

        //导航抽屉,从资源的图标
        navMenuIcons = getResources()
                .obtainTypedArray(R.array.nav_drawer_icons);

        // mDrawerLayout =(DrawerLayout)findViewById(R.id.drawer_layout);
        mDrawerLayout =(DrawerLayout)getLayoutInflater()膨胀(R.layout.activity_main,空)。
        // mDrawerList =(ListView控件)findViewById(R.id.list_slidermenu);
        mDrawerList =(ListView控件)mDrawerLayout.findViewById(R.id.list_slidermenu);

        navDrawerItems =新的ArrayList< NavDrawerItem>();

        //添加导航抽屉里的物品数组
        // 家
        navDrawerItems.add(新NavDrawerItem(navMenuTitles [0],navMenuIcons.getResourceId(0,-1)));
        //查找人​​员
        navDrawerItems.add(新NavDrawerItem(navMenuTitles [1],navMenuIcons.getResourceId(1,-1)));
        //照片
        navDrawerItems.add(新NavDrawerItem(navMenuTitles [2],navMenuIcons.getResourceId(2,-1)));
        //社区,这里将添加计数器
        navDrawerItems.add(新NavDrawerItem(navMenuTitles [3],navMenuIcons.getResourceId(3,-1)));
        //网页
        navDrawerItems.add(新NavDrawerItem(navMenuTitles [4],navMenuIcons.getResourceId(4,-1)));
        //热点,我们将在这里添加计数器
        navDrawerItems.add(新NavDrawerItem(navMenuTitles [5],navMenuIcons.getResourceId(5,-1)));


        //回收类型数组
        navMenuIcons.recycle();

        mDrawerList.setOnItemClickListener(新SlideMenuClickListener());

        //设置导航抽屉名单适配器
        适配器=新NavDrawerListAdapter(getApplicationContext()
                navDrawerItems);
        mDrawerList.setAdapter(适配器);

        mDrawerToggle =新ActionBarDrawerToggle(这一点,mDrawerLayout,
                R.drawable.ic_drawer,//导航菜单切换图标
                R.string.app_name,//导航抽屉打开 - 说明访问
                R.string.app_name //导航抽屉关闭 - 说明访问
        ){
            公共无效onDrawerClosed(查看视图){
                。getSupportActionBar()的setTitle(mTitle);
                //调用prepareOptionsMenu()来显示操作栏图标
                invalidateOptionsMenu();
            }

            公共无效onDrawerOpened(查看drawerView){
                。getSupportActionBar()的setTitle(mDrawerTitle);
                //调用prepareOptionsMenu()隐藏操作栏图标
                invalidateOptionsMenu();
            }
        };
        mDrawerLayout.setDrawerListener(mDrawerToggle);

        如果(savedInstanceState == NULL){
            //关于第一导航项目首次显示视图
            displayView(0);
        }

    }
 

最后,我只需要延长 BaseActivity 类和code像往常一样。

更新

据答案,这是我的工作overrided 的setContentView

  @覆盖
    公共无效的setContentView(最终诠释layoutResID){
        // TODO自动生成方法存根
        mDrawerLayout =(DrawerLayout)getLayoutInflater()膨胀(R.layout.activity_main,空)。 //你的基地,这里布局
        actContent =(的FrameLayout)mDrawerLayout.findViewById(R.id.frame_container);

        。getLayoutInflater()膨胀(layoutResID,actContent,真正的);
        super.setContentView(mDrawerLayout);

        mTitle = mDrawerTitle =的getTitle();

        //负荷滑动菜单项
        navMenuTitles = getResources()getStringArray(R.array.nav_drawer_items)。

        //导航抽屉,从资源的图标
        navMenuIcons = getResources()
                .obtainTypedArray(R.array.nav_drawer_icons);

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

        navDrawerItems =新的ArrayList< NavDrawerItem>();

        //添加导航抽屉里的物品数组
        // 家
        navDrawerItems.add(新NavDrawerItem(navMenuTitles [0],navMenuIcons.getResourceId(0,-1)));
        //查找人​​员
        navDrawerItems.add(新NavDrawerItem(navMenuTitles [1],navMenuIcons.getResourceId(1,-1)));
        //照片
        navDrawerItems.add(新NavDrawerItem(navMenuTitles [2],navMenuIcons.getResourceId(2,-1)));
        //社区,这里将添加计数器
        navDrawerItems.add(新NavDrawerItem(navMenuTitles [3],navMenuIcons.getResourceId(3,-1)));
        //网页
        navDrawerItems.add(新NavDrawerItem(navMenuTitles [4],navMenuIcons.getResourceId(4,-1)));
        //热点,我们将在这里添加计数器
        navDrawerItems.add(新NavDrawerItem(navMenuTitles [5],navMenuIcons.getResourceId(5,-1)));


        //回收类型数组
        navMenuIcons.recycle();

        mDrawerList.setOnItemClickListener(新SlideMenuClickListener());

        //设置导航抽屉名单适配器
        适配器=新NavDrawerListAdapter(getApplicationContext()
                navDrawerItems);
        mDrawerList.setAdapter(适配器);

        mDrawerToggle =新ActionBarDrawerToggle(这一点,mDrawerLayout,
                R.drawable.ic_drawer,//导航菜单切换图标
                R.string.app_name,//导航抽屉打开 - 说明访问
                R.string.app_name //导航抽屉关闭 - 说明访问
        ){
            公共无效onDrawerClosed(查看视图){
                。getSupportActionBar()的setTitle(mTitle);
                //调用prepareOptionsMenu()来显示操作栏图标
                invalidateOptionsMenu();
            }

            公共无效onDrawerOpened(查看drawerView){
                。getSupportActionBar()的setTitle(mDrawerTitle);
                //调用prepareOptionsMenu()隐藏操作栏图标
                invalidateOptionsMenu();
            }
        };
        mDrawerLayout.setDrawerListener(mDrawerToggle);

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

解决方案

更​​改的setContentView()这样的...

  @覆盖
公共无效的setContentView(INT layoutResID){
    mDrawerLayout =(DrawerLayout)getLayoutInflater()膨胀(R.layout.activity_main,空)。
    actContent =(的FrameLayout)mDrawerLayout.findViewById(R.id.frame_container);
    //设置抽屉布局,活动的主要内容视图。
    的setContentView(mDrawerLayout);
    //里面添加framelayout.ie BaseActivities布局frame_container
    。getLayoutInflater()膨胀(layoutResID,actContent,真正的);
}
 

I tried to follow this answer, with the main idea is to override the setContentView in the BaseActivity, the activity that will be extended by all activity so only BaseActivity will have the navigation drawer.

However, my navigation is never shown (even in BaseActivity) after i tried to implement the answer. This is what i did :

This is the navigation drawer's 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>

This is my overrided setContentView (in BaseActivity) :

@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);
    }

And this is my onCreate on BaseActivity, note that i use getLayoutInflater().inflate instead of setContentView :

@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);
        }

    }

And finally, i just need to extend the BaseActivity class and code like usual.

UPDATE

According to the answer, this is my WORKING overrided 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);*/
    }
解决方案

Change your setContentView() like this...

@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);
}
