我有一个
导航抽屉
,它应该出现在我的所有活动中

我看到了许多类似的问题&找到了一个解决方案,比如用其他活动扩展main活动

所以我把我的主要活动扩展到了第二个活动,但是第二个活动中没有显示抽屉

main活动

public class MainActivity extends ActionBarActivity
{
    private ListView mDrawerList;
    private DrawerLayout mDrawer;
    private CustomActionBarDrawerToggle mDrawerToggle;
    private String[] menuItems;

@Override
protected void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    supportRequestWindowFeature(WindowCompat.FEATURE_ACTION_BAR);
    // getSupportActionBar().hide();
    setContentView(R.layout.activity_main_drawer);

    // enable ActionBar app icon to behave as action to toggle nav drawer
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);
    getSupportActionBar().setHomeButtonEnabled(true);

    mDrawer = (DrawerLayout) findViewById(R.id.drawer_layout);

    // set a custom shadow that overlays the main content when the drawer
    // opens
    mDrawer.setDrawerShadow(R.drawable.drawer_shadow, GravityCompat.START);

    _initMenu();
    mDrawerToggle = new CustomActionBarDrawerToggle(this, mDrawer);
    mDrawer.setDrawerListener(mDrawerToggle);

}

private void _initMenu()
{
    NsMenuAdapter mAdapter = new NsMenuAdapter(this);

    // Add Header
    mAdapter.addHeader(R.string.ns_menu_main_header);

    // Add first block

    menuItems = getResources().getStringArray(R.array.ns_menu_items);
    String[] menuItemsIcon = getResources().getStringArray(R.array.ns_menu_items_icon);

    int res = 0;
    for (String item : menuItems)
    {

        int id_title = getResources().getIdentifier(item, "string", this.getPackageName());
        int id_icon = getResources().getIdentifier(menuItemsIcon[res], "drawable", this.getPackageName());

        NsMenuItemModel mItem = new NsMenuItemModel(id_title, id_icon);
        // if (res==1) mItem.counter=12; //it is just an example...
        // if (res==3) mItem.counter=3; //it is just an example...
        mAdapter.addItem(mItem);
        res++;
    }

    mAdapter.addHeader(R.string.ns_menu_main_header2);

    mDrawerList = (ListView) findViewById(R.id.drawer);
    if (mDrawerList != null)
        mDrawerList.setAdapter(mAdapter);

    mDrawerList.setOnItemClickListener(new DrawerItemClickListener());

}

@Override
protected void onPostCreate(Bundle savedInstanceState)
{
    super.onPostCreate(savedInstanceState);
    // Sync the toggle state after onRestoreInstanceState has occurred.
    mDrawerToggle.syncState();
}

@Override
public void onConfigurationChanged(Configuration newConfig)
{
    super.onConfigurationChanged(newConfig);
    mDrawerToggle.onConfigurationChanged(newConfig);
}

@Override
public boolean onCreateOptionsMenu(Menu menu)
{
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.control_menu, menu);
    return super.onCreateOptionsMenu(menu);
}

/* Called whenever we call invalidateOptionsMenu() */
@Override
public boolean onPrepareOptionsMenu(Menu menu)
{
    // If the nav drawer is open, hide action items related to the content
    // view
    boolean drawerOpen = mDrawer.isDrawerOpen(mDrawerList);
    menu.findItem(R.id.action_keyboard).setVisible(!drawerOpen);
    return super.onPrepareOptionsMenu(menu);
}

@Override
public boolean onOptionsItemSelected(MenuItem item)
{
    /*
     * The action bar home/up should open or close the drawer.
     * ActionBarDrawerToggle will take care of this.
     */
    if (mDrawerToggle.onOptionsItemSelected(item))
    {
        return true;
    }

    // Handle your other action bar items...
    return super.onOptionsItemSelected(item);
}

private class CustomActionBarDrawerToggle extends ActionBarDrawerToggle
{

    public CustomActionBarDrawerToggle(Activity mActivity, DrawerLayout mDrawerLayout)
    {
        super(mActivity, mDrawerLayout, R.drawable.ic_drawer, R.string.ns_menu_open, R.string.ns_menu_close);
    }

    @Override
    public void onDrawerClosed(View view)
    {
        getSupportActionBar().setTitle(getString(R.string.ns_menu_close));
        supportInvalidateOptionsMenu(); // creates call to
                                        // onPrepareOptionsMenu()
    }

    @Override
    public void onDrawerOpened(View drawerView)
    {
        getSupportActionBar().setTitle(getString(R.string.ns_menu_open));
        supportInvalidateOptionsMenu(); // creates call to
                                        // onPrepareOptionsMenu()
    }
}

private class DrawerItemClickListener implements ListView.OnItemClickListener
{

    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id)
    {
        Intent intent = new Intent(MainActivity.this, Tutorial.class);
        startActivity(intent);

    }

}

 }
 public class Tutorial extends MainActivity
{
    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.help);
    }

}

您从派生类
onCreate
中省略了
@Override


更新:我不确定调用两次
setContentView
会有什么影响,但这可能就是问题所在。分离出设置抽屉的代码,并从两个
onCreate
方法调用它

TutorialActivity
onCreate
中,不要调用
setContentView
,而是执行以下操作:

@Override
protected void onCreate(Bundle savedInstanceState)
{
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    LayoutInflater inflater = (LayoutInflater) this
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View contentView = inflater.inflate(R.layout.help, null, false);
    mDrawer.addView(contentView, 0); 
}

使
main活动中的
mDrawer
受保护。在
R.layout.activity\u main\u drawer
中,只需保留drawer标签和重力向左(或向右)的元素。

我制作了一个BaseActivity活动,扩展SherlockActivity(或ActionBarActivity,如果是您的情况)

然后,将所有活动扩展为BaseActivity,如:

public class GlossaryActivity extends BaseActivity
稍后,您必须将活动布局替换为与您的活动对应的布局,我在BaseActivity中创建了如下方法:

protected void replaceContentLayout(int sourceId, int destinationId) {
    View contentLayout = findViewById(destinationId);

    ViewGroup parent = (ViewGroup) contentLayout.getParent();
    int index = parent.indexOfChild(contentLayout);

    parent.removeView(contentLayout);
    contentLayout = getLayoutInflater().inflate(sourceId, parent, false);
    parent.addView(contentLayout, index);
}
我在每个活动中对onCreate方法调用了此方法:

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    super.replaceContentLayout(R.layout.activity_glossary, super.CONTENT_LAYOUT_ID);

}

super.CONTENT\u LAYOUT\u ID
是BaseActivity的FrameLayout,其他参数是您要替换为的布局。。希望能有所帮助

首先,这是一个概念

第二个,这也是一个

最后,这里是所有答案在一个地方的组合


基本活动

这是所有其他活动的基本活动

您可以根据需要扩展活动或片段活动等

导航抽屉
在此设置一次

public class BaseActivity extends FragmentActivity {

    protected DrawerLayout mDrawer;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        this.requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.base_layout);

        mDrawer = (DrawerLayout) findViewById(R.id.drawer_layout);

        //This is about creating custom listview for navigate drawer
        //Implementation for NavigateDrawer HERE !
        ArrayList<DrawerListItem> drawerListItems = new ArrayList<DrawerListItem>();
        drawerListItems.add(new DrawerListItem(0,"AIR° DEVICES"));
        drawerListItems.add(new DrawerListItem(1,"A/C Device [1]"));
        drawerListItems.add(new DrawerListItem(1,"A/C Device [2]"));
        drawerListItems.add(new DrawerListItem(1,"A/C Device [3]"));
        drawerListItems.add(new DrawerListItem(0,"AIR° FEATURES"));
        drawerListItems.add(new DrawerListItem(2,"SLEEP MODE"));
        drawerListItems.add(new DrawerListItem(2,"TRACKING MODE"));
        drawerListItems.add(new DrawerListItem(2,"SETTINGS"));
        DrawerAdapter mDrawerAdapter = new DrawerAdapter(this, R.layout.drawer_list_header, drawerListItems);
        ListView mDrawerList = (ListView) findViewById(R.id.left_drawer);
        mDrawerList.setAdapter(mDrawerAdapter);
    }

}
所有其他活动

其他
Activity
只是扩展了
BaseActivity
,并定义了如下代码

对于特定的活动,
导航抽屉将出现

mDrawer
是表单
BaseActivity
。它是一个受保护的变量

public class Screen1 extends BaseActivity

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        LayoutInflater inflater = (LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

        //inflate your activity layout here!
        View contentView = inflater.inflate(R.layout.screen1, null, false);
        mDrawer.addView(contentView, 0);

        //Do the rest as you want for each activity
    }
屏幕1 XML示例

根据您的意愿设计每个活动。不再有
导航抽屉
布局

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:orientation="vertical"
              android:layout_width="match_parent"
              android:layout_height="match_parent">

</LinearLayout>

注意


在此实现中,
导航抽屉
不与操作栏绑定。如果您希望这样做,请在
BaseActivity
中进行。此外,本指南并未涵盖所有要求。这只是一个样本。

我也有这个问题。这是我的实现:

activity\u main.xml-CoordinatorLayout中索引1处的子项是content\u main.xml,我可以在代码中更改它

<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    tools:openDrawer="start">

    <android.support.design.widget.CoordinatorLayout
        android:id="@+id/coordinator"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:fitsSystemWindows="true">

        <android.support.design.widget.AppBarLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:theme="@style/AppTheme.AppBarOverlay">

            <android.support.v7.widget.Toolbar
                android:id="@+id/toolbar"
                android:layout_width="match_parent"
                android:layout_height="?attr/actionBarSize"
                android:background="?attr/colorPrimary"
                app:popupTheme="@style/AppTheme.PopupOverlay" />

        </android.support.design.widget.AppBarLayout>

        **<include layout="@layout/content_main" />**

        <android.support.design.widget.FloatingActionButton
            android:id="@+id/fab"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="bottom|end"
            android:layout_margin="@dimen/fab_margin"
            android:src="@android:drawable/ic_dialog_email" />

    </android.support.design.widget.CoordinatorLayout>

    <android.support.design.widget.NavigationView
        android:id="@+id/nav_view"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:fitsSystemWindows="true"
        app:headerLayout="@layout/nav_header_main"
        app:menu="@menu/activity_main_drawer" />

</android.support.v4.widget.DrawerLayout>
现在,在其他活动中,您只需扩展MainActivity并调用此方法,并为其提供必要的参数:

public class AnotherActivity extends MainActivity {

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        new MyLayoutInflater().inflate(this,R.layout.content_activity_another, getSupportActionBar(), getIntent());

    }
}

好的,这是一个很好的方法,我只在特殊的调试构建中使用它来实时设置视图的属性(设计工具)

它的优点是您可以像往常一样使用您的孩子的活动,而不需要不同答案中要求的特殊行为

因此,在BaseActivity中,您可以添加:

@Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);

// WARNING: Hacky, use carefully!!!
ViewGroup androidBaseView = (ViewGroup) findViewById(android.R.id.content);
//this one in what child activity has just set in setContentView()
ViewGroup childContent = (ViewGroup) androidBaseView.getChildAt(0);

View drawerView = LayoutInflater.from(this)
    .inflate(R.layout.base_activity_drawer, androidBaseView, false);
FrameLayout frameLayout = (FrameLayout) drawerView.findViewById(R.id.content);
androidBaseView.removeView(childContent);
frameLayout.addView(childContent);
androidBaseView.addView(drawerView);
}
抽屉的xml只是:

  <android.support.v4.widget.DrawerLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:id="@+id/nav_drawer"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:fitsSystemWindows="true">
  <FrameLayout
    android:id="@+id/content"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>
  <LinearLayout
    android:id="@+id/drawer_for_components"
    android:layout_width="240dp"
    android:layout_height="match_parent"
    android:layout_gravity="end"
    android:orientation="vertical"
    android:fitsSystemWindows="true"
    />
</android.support.v4.widget.DrawerLayout>

在android studio中,有一种简单快捷的方法:

  • 从gallery中创建一个新活动(导航抽屉活动),并将其命名为任何您想要的名称,android studio将为您创建所有内容(您可以稍后自定义的类和xml文件)

  • 在其他活动中,您应该扩展导航抽屉活动,并确保这些其他活动在清单文件中具有“无操作栏”(android:theme=“@style/AppTheme.NoActionBar”)

  • 您应修改其他活动,如下所示:

    public class Mainactivity extends NavActivity
    {
    super.onCreate(savedInstanceState);
       LayoutInflater inflater = (LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
       //inflate your activity layout here!
       View contentView = inflater.inflate(R.layout.activity_main, null, false);
       drawer.addView(contentView, 0);
    }
    
  • 注意:mainactivity将扩展NavActivity的操作栏,NavActivity具有调用导航抽屉的全功能操作栏


    我希望它能与您一起工作

    现在您应该使用单活动应用程序架构()


    然后简单地将导航抽屉添加到主活动中

    我一周前也尝试过。没有片段会使代码效率非常低…所以最好使用fragments.mDrawer.addView(contentView,0);给出错误。。。我需要做哪些更改才能使其正常工作?我遵循了这些说明,但当我按下抽屉中的任何按钮时,我的应用程序都会立即崩溃。是的,它没有与ActionBar绑定。这是一个真正的问题。我浪费了很多时间,但是没有调用选项ItemSelected,因此,返回箭头不起作用。这确实起作用。现在,为了使用导航抽屉,不再需要使用fragment了。谢谢,我的朋友。这真的很有用,花了一整天的时间。用了这个,几秒钟就完成了。谢谢请将R.layout.activity\u main\u drawer xml文件添加到回答什么?为什么不使用
    @我认为是因为抽屉布局应该是最重要的元素。无论如何,我建议更好的解决方案是现在就使用片段。如果有办法让用户分享如何。我删除setContentView()并写下你所说的,但不为我工作。。。my baseActivity在第二个活动中打开。在第一个
    充气
    方法中,您不使用
    getIntent
    参数。
    @Override
    protected void onPostCreate(Bundle savedInstanceState) {
    super.onPostCreate(savedInstanceState);
    
    // WARNING: Hacky, use carefully!!!

    ViewGroup childContent = (ViewGroup) androidBaseView.getChildAt(0);
    
    View drawerView = LayoutInflater.from(this)
        .inflate(R.layout.base_activity_drawer, androidBaseView, false);
    FrameLayout frameLayout = (FrameLayout) drawerView.findViewById(R.id.content);
    androidBaseView.removeView(childContent);
    frameLayout.addView(childContent);
    androidBaseView.addView(drawerView);
