如何在所有活动中显示导航抽屉？

Question

我有一个Navigation Drawer，它应该出现在我的所有活动中。

我看到了很多类似的问题，并找到了一个解决方案，比如用其他活动扩展 MainActivity。

所以我将我的主要活动扩展到我的第二个活动。但是抽屉没有显示在第二个活动中

MainActivity

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);

    }

}

 }

第二活动

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

}

Answer 1

这是我的实现..希望对您有所帮助

FIRST，这个POST 是概念。

SECOND，这也是KEY之一。

终于，这里是所有答案的组合

---

基础活动

这是所有其他活动的基础活动

您可以根据需要扩展 Activity 或 FragmentActivity 等。

Navigation Drawer在这里设置一次。

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);
    }

}

基础活动 XML

此 xml 布局适用于 Navigation Drawer

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

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

    </FrameLayout>

    <!-- The navigation drawer -->
    <ListView
            android:id="@+id/left_drawer"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_gravity="left"
            android:scrollingCache="false"
            android:background="@drawable/drawer_bg"
            android:divider="@null"
            android:choiceMode="singleChoice"/>

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

所有其他活动

其他Activity 只是扩展BaseActivity 并定义代码如下。

Navigation Drawer 将针对特定活动显示。

mDrawer 是BaseActivity 的形式。这是一个protected 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

按照您的意愿设计每个活动。没有更多的Navigation Drawer 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，Navigation Drawer 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。这只是一个示例。

Answer 2

在TutorialActivity 的onCreate 中不要调用setContentView，而是这样做：

@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mDrawer 中的MainActivity 受保护。在R.layout.activity_main_drawer 中只保留抽屉标签和重力左（或右）元素。

Answer 3

我做了一个 BaseActivity 活动，它扩展了 SherlockActivity（或 ActionBarActivity，如果是你的情况）

public class BaseActivity extends SherlockActivity

然后，让您的所有活动都扩展 BaseActivity，例如：

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 中做了一个这样的方法：

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activity的onCreate方法上调用了这个方法：

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

}

super.CONTENT_LAYOUT_ID是BaseActivity的FrameLayout，其他参数是你要替换的布局

Answer 4

您从派生类onCreate 中省略了@Override。

更新：我不确定两次调用setContentView 会产生什么影响，但这可能是问题所在。分离出设置抽屉的代码，并从两个onCreate 方法中调用它。

Answer 5

我也有这个问题。这是我的实现：

activity_main.xml - CoordinatorLayout 中索引 1 处的子项是 content_main.xml，我可以在代码中更改。

<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>

我创建了一个使用膨胀其他活动 UI 的类：

public class MyLayoutInflater {

    public void inflate(Activity activity, int LayoutResource, android.app.ActionBar getSupportActionBar, Intent getIntent){
        CoordinatorLayout coordinatorLayout = (CoordinatorLayout) activity.findViewById(R.id.coordinator);
        android.view.LayoutInflater inflater = (android.view.LayoutInflater) activity
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View contentView = inflater.inflate(LayoutResource, null, false);

        //change i so that it suits the child number in you coordinator layout
        int i = 1;
        coordinatorLayout.removeViewAt(i);
        coordinatorLayout.addView(contentView, i);
        getSupportActionBar.setTitle(actionBarTitle);
    }

    public void inflate(Activity activity, int LayoutResource, android.support.v7.app.ActionBar getActionBar, String actionBarTitle){
        CoordinatorLayout coordinatorLayout = (CoordinatorLayout) activity.findViewById(R.id.coordinator);
        android.view.LayoutInflater inflater = (android.view.LayoutInflater) activity
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View contentView = inflater.inflate(LayoutResource, null, false);

        //change i so that it suits the child number in you coordinator layout
        int i = 1;
        coordinatorLayout.removeViewAt(i);
        coordinatorLayout.addView(contentView, i);
        getActionBar.setTitle(actionBarTitle);
    }

}

现在在其他活动上，您所要做的就是扩展 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());

    }
}

Answer 6

好的，这是一种很老套的方法，我只将它用于特殊类型的调试构建，以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，而不会出现不同答案中需要的特殊行为。

所以在 BaseActvity 中你可以添加：

@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);
}

而抽屉的 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>

Answer 7

这是在 android studio 中简单快速的方法：

1. 从图库中创建一个新的活动（导航抽屉活动），并将其命名为您想要的任何名称，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）

2. 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"）

3. 您应该如下修改您的其他活动：

   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会扩展NavActivity的action bar，NavActivity有一个全功能的action bar会调用导航抽屉

希望对你有用

Answer 8

现在您应该使用单活动应用架构 (source)。

然后简单地将导航抽屉添加到主活动

Answer 9

你可以简单地使用<include/> 通过创建导航抽屉

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

然后在其中包含布局

    <include
        layout="@layout/activity_accounts"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

在你的主要活动中制作setContentView(R.layout.your_drawer_activity)

请注意，如果您使用此方法，则必须为您拥有的每个活动创建一个导航抽屉布局，除非您找到了一种以编程方式执行包含的方法。
