不同活动中的相同导航抽屉

标签: android android-activity navigation navigation-drawer drawer

我制作了一个有效的导航抽屉,如developer.android.com网站上的教程所示。但现在,我想使用一个导航抽屉,我在NavigationDrawer.class中为我的应用程序中的多个活动创建。

我的问题是,如果有人在这里可以制作一个小教程,这解释了如何使用一个导航抽屉进行多项活动。

我在本答案中首先阅读了它 Android Navigation Drawer on multiple Activities

但它对我的项目无效

public class NavigationDrawer extends Activity {
public DrawerLayout drawerLayout;
public ListView drawerList;
private ActionBarDrawerToggle drawerToggle;

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
    drawerToggle = new ActionBarDrawerToggle((Activity) this, drawerLayout, R.drawable.ic_drawer, 0, 0) {

        public void onDrawerClosed(View view) {
            getActionBar().setTitle(R.string.app_name);
        }

        public void onDrawerOpened(View drawerView) {
            getActionBar().setTitle(R.string.menu);
        }
    };
    drawerLayout.setDrawerListener(drawerToggle);

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

    layers = getResources().getStringArray(R.array.layers_array);
    drawerList = (ListView) findViewById(R.id.left_drawer);
    View header = getLayoutInflater().inflate(R.layout.drawer_list_header, null);
    drawerList.addHeaderView(header, null, false);
    drawerList.setAdapter(new ArrayAdapter<String>(this, R.layout.drawer_list_item, android.R.id.text1,
            layers));
    View footerView = ((LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE)).inflate(
            R.layout.drawer_list_footer, null, false);
    drawerList.addFooterView(footerView);

    drawerList.setOnItemClickListener(new OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> arg0, View arg1, int pos, long arg3) {
            map.drawerClickEvent(pos);
        }
    });
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {

    if (drawerToggle.onOptionsItemSelected(item)) {
        return true;
    }
    return super.onOptionsItemSelected(item);

}

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

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

在这个活动中,我想拥有导航抽屉,所以我扩展了'NavigationDrawer',在其他一些活动中,我希望用户使用相同的导航抽屉

  public class SampleActivity extends NavigationDrawer {...}

我不知道该改变什么......

如果您想要导航抽屉,则应使用片段。 我上周遵循了本教程,效果很好:

http://developer.android.com/training/implementing-navigation/nav-drawer.html

您也可以从本教程下载示例代码,了解如何执行此操作。


没有片段:

这是您的BaseActivity代码:

public class BaseActivity extends Activity
{
    public DrawerLayout drawerLayout;
    public ListView drawerList;
    public String[] layers;
    private ActionBarDrawerToggle drawerToggle;
    private Map map;

    protected void onCreate(Bundle savedInstanceState)
    {
        // R.id.drawer_layout should be in every activity with exactly the same id.
        drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);

        drawerToggle = new ActionBarDrawerToggle((Activity) this, drawerLayout, R.drawable.ic_drawer, 0, 0) 
        {
            public void onDrawerClosed(View view) 
            {
                getActionBar().setTitle(R.string.app_name);
            }

            public void onDrawerOpened(View drawerView) 
            {
                getActionBar().setTitle(R.string.menu);
            }
        };
        drawerLayout.setDrawerListener(drawerToggle);

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

        layers = getResources().getStringArray(R.array.layers_array);
        drawerList = (ListView) findViewById(R.id.left_drawer);
        View header = getLayoutInflater().inflate(R.layout.drawer_list_header, null);
        drawerList.addHeaderView(header, null, false);
        drawerList.setAdapter(new ArrayAdapter<String>(this, R.layout.drawer_list_item, android.R.id.text1,
                layers));
        View footerView = ((LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE)).inflate(
                R.layout.drawer_list_footer, null, false);
        drawerList.addFooterView(footerView);

        drawerList.setOnItemClickListener(new OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> arg0, View arg1, int pos, long arg3) {
                map.drawerClickEvent(pos);
            }
        });
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {

        if (drawerToggle.onOptionsItemSelected(item)) {
            return true;
        }
        return super.onOptionsItemSelected(item);

    }

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

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

需要有导航抽屉的所有其他活动应该扩展此活动而不是活动本身,例如:

public class AnyActivity extends BaseActivity
{
    //Because this activity extends BaseActivity it automatically has the navigation drawer
    //You can just write your normal Activity code and you don't need to add anything for the navigation drawer
}

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">
    <!-- The main content view -->
    <FrameLayout
        android:id="@+id/content_frame"
        android:layout_width="match_parent"
        android:layout_height="match_parent" >
        <!-- Put what you want as your normal screen in here, you can also choose for a linear layout or any other layout, whatever you prefer -->
    </FrameLayout>
    <!-- The navigation drawer -->
    <ListView android:id="@+id/left_drawer"
        android:layout_width="240dp"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:choiceMode="singleChoice"
        android:divider="@android:color/transparent"
        android:dividerHeight="0dp"
        android:background="#111"/>
</android.support.v4.widget.DrawerLayout>

修改

我自己遇到了一些困难,所以如果你得到NullPointerExceptions,这里有一个解决方案。在BaseActivity中,将onCreate函数更改为protected void onCreateDrawer()。其余的可以保持不变。在扩展BaseActivity的活动中,按以下顺序放置代码:

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity);
    super.onCreateDrawer();

这有助于我解决我的问题,希望它有所帮助!

如果您有任何问题可以随意询问,可以使用多种活动创建导航抽屉。


编辑2:

正如@GregDan所说, BaseActivity 也可以覆盖setContentView()并在那里调用onCreateDrawer:

@Override 
public void setContentView(@LayoutRes int layoutResID) 
{ 
    super.setContentView(layoutResID); 
    onCreateDrawer() ;
}

我找到了最好的实施方案。它位于Google I/O 2014应用。

他们使用与凯文相同的方法。如果您可以从I / O应用程序中的所有不需要的东西中抽象出来,那么您可以提取所需的所有内容,Google可以确保它正确使用导航抽屉模式。 每个活动可选择DrawerLayout作为其主要布局。有趣的是如何完成导航到其他屏幕。它在BaseActivity中实现,如下所示:

private void goToNavDrawerItem(int item) {
        Intent intent;
        switch (item) {
            case NAVDRAWER_ITEM_MY_SCHEDULE:
                intent = new Intent(this, MyScheduleActivity.class);
                startActivity(intent);
                finish();
                break;

这与通过片段事务替换当前片段的常见方式不同。但是用户没有发现视觉差异。

答案 2 :(得分:7)

对于任何想要做原始海报所要求的人,请考虑使用片段而不是凯文所说的方式。这是一个关于如何做到这一点的优秀教程:

https://github.com/codepath/android_guides/wiki/Fragment-Navigation-Drawer

如果您选择使用活动而不是片段,则每次导航到新活动时都会遇到导航抽屉被重新创建的问题。这导致每次导航抽屉的丑陋/慢速渲染。

答案 3 :(得分:7)

所以这个答案是迟了几年但有人可能会欣赏它。 Android为我们提供了一个新的小部件,它可以更轻松地使用一个导航抽屉和多个活动。

android.support.design.widget.NavigationView是模块化的,在菜单文件夹中有自己的布局。您使用它的方式是以下列方式包装xml布局:

  1. Root Layout是一个android.support.v4.widget.DrawerLayout,它包含两个子节点:正在封装的布局<include ... />(参见2)和android.support.design.widget .NavigationView。

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

  2. nav_header_main只是一个LinearLayout,其导向Drawar标题的orientation = vertical。

    activity_main_drawer是res / menu目录中的菜单xml。它可以包含您选择的项目和组。如果您使用AndroidStudio图库,向导将为您制作一个基本的向导,您可以看到您的选项。

    1. 应用程序栏布局现在通常是android.support.design.widget.CoordinatorLayout,它将包含两个子项:android.support.design.widget.AppBarLayout(包含android.support.v7.widget) .Toolbar)和<include ... >的实际内容(见3)。

      <android.support.design.widget.CoordinatorLayout
          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:layout_width="match_parent"
          android:layout_height="match_parent"
          tools:context="yourpackage.MainActivity">
      
       <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" />
      

    2. 内容布局可以是您想要的任何布局。这是包含活动主要内容的布局(不包括导航栏或应用栏)。

    3. 现在,关于所有这些的很酷的事情是你可以将这两个布局中的每个活动包装起来,但让你的NavigationView(参见步骤1)始终指向activity_main_drawer(或其他)。这意味着您将在所有活动中使用相同的(*)导航抽屉。

      • 他们不会成为NavigationView的实例,但公平地说,即使使用上面列出的BaseActivity解决方案,这也是不可能的。

答案 4 :(得分:5)

我的建议是:根本不使用活动,而是使用片段,并在显示第一个片段的容器(例如,线性布局)中替换它们。

该代码在Android Developer Tutorials中提供,您只需自定义。

http://developer.android.com/training/implementing-navigation/nav-drawer.html

建议您在应用程序中使用越来越多的片段,应用程序本地应该只有四个基本活动,您在AndroidManifest.xml中提到的除外部活动之外(例如FacebookActivity):

  1. SplashActivity:不使用片段,并使用FullScreen主题。

  2. LoginSignUpActivity:根本不需要NavigationDrawer,也不需要后退按钮,所以只需使用普通工具栏,但至少需要3或4个片段。使用no-action-bar主题

  3. HomeActivity或DashBoard活动:使用no-action-bar主题。在这里,您需要导航抽屉,随后的所有屏幕都将是片段或嵌套片段,直到叶子视图,与共享抽屉。在此活动中,所有设置,用户配置文件等都将作为片段。 此处的片段不会添加到后堆栈中,而是会从抽屉菜单项中打开。对于需要后退按钮而不是抽屉的碎片,下面有第四种活动。

  4. 没有抽屉的活动。此活动在顶部有一个后退按钮,内部的片段将共享相同的操作栏。这些片段将被添加到后台,因为会有导航历史记录。

  5. [如需进一步指导,请参阅:https://stackoverflow.com/a/51100507/787399]

以baseactivity更新此代码。并且不要忘记在您的活动xml中包含drawer_list_header。

super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_ACTION_BAR_OVERLAY);
setContentView(R.layout.drawer_list_header);

并且不要在您的活动中使用request()。但是在单击图像时仍然看不到抽屉......通过拖动它将在没有列表项的情况下可见。我尝试了很多但没有成功。需要一些锻炼......

有了@Kevin van Mierlo的回答,你也能够实现几个抽屉。例如,默认菜单位于左侧(开始),另一个可选菜单位于右侧,仅在加载确定片段时显示。

我已经能够做到这一点。

将它用于toolbar.xml

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

    <android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@color/colorPrimary"
        android:elevation="4dp"
        android:id="@+id/toolbar"
        android:theme="@style/ThemeOverlay.AppCompat.Dark"


        >

我在Kotlin这样做:

open class BaseAppCompatActivity : AppCompatActivity(), NavigationView.OnNavigationItemSelectedListener {

protected lateinit var drawerLayout: DrawerLayout
protected lateinit var navigationView: NavigationView
@Inject
lateinit var loginService: LoginService

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    Log.d("BaseAppCompatActivity", "onCreate()")
    App.getComponent().inject(this)
    drawerLayout = findViewById(R.id.drawer_layout) as DrawerLayout

    val toolbar = findViewById(R.id.toolbar) as Toolbar
    setSupportActionBar(toolbar)

    navigationView = findViewById(R.id.nav_view) as NavigationView
    navigationView.setNavigationItemSelectedListener(this)

    val toggle = ActionBarDrawerToggle(this, drawerLayout, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close)

    drawerLayout.addDrawerListener(toggle)
    toggle.syncState()
    toggle.isDrawerIndicatorEnabled = true

    val navigationViewHeaderView = navigationView.getHeaderView(0)
    navigationViewHeaderView.login_txt.text = SharedKey.username
}
private inline fun <reified T: Activity> launch():Boolean{
    if(this is T) return closeDrawer()
    val intent = Intent(applicationContext, T::class.java)
    startActivity(intent)
    finish()
    return true
}

private fun closeDrawer(): Boolean {
    drawerLayout.closeDrawer(GravityCompat.START)
    return true
}
override fun onNavigationItemSelected(item: MenuItem): Boolean {
    val id = item.itemId

    when (id) {
        R.id.action_tasks -> {
            return launch<TasksActivity>()
        }
        R.id.action_contacts -> {
            return launch<ContactActivity>()
        }
        R.id.action_logout -> {
            createExitDialog(loginService, this)
        }
    }
    return false
}
}

抽屉的活动必须继承此BaseAppCompatActivity,在设置内容后调用super.onCreate(实际上,可以移动到某个init方法)并在其布局中具有相应的ID元素

答案 10 :(得分:1)

我的回答只是一个概念性的回答,没有任何源代码。对于像我这样的一些读者来说,这可能很有用。

这取决于您最初如何构建应用程序。基本上有两种方法。

  1. 您创建一个活动(基本活动),所有其他视图和屏幕均为片段。该基本活动包含“抽屉和协调器布局”的实现。实际上,这是我的首选方式,因为拥有独立的小片段将使应用程序开发更轻松,更流畅。

  2. 如果您使用活动开始了应用程序开发,每个屏幕一个,那么您可能会创建基础活动,所有其他活动都将以此为基础。基本活动将包含抽屉和协调器实现的代码。任何需要抽屉实现的活动都可以从基本活动扩展。

我个人更希望避免使用没有任何组织的片段和活动。这会使开发更加困难,并最终使您陷入困境。如果已完成,请重构代码。

使用片段在MainActivity中创建导航抽屉 在MainActivity中初始化导航抽屉
现在,在所有其他活动中,您想要使用相同的导航抽屉,将DrawerLayout作为基础,将片段作为导航抽屉。只需在片段中设置指向您的片段Java文件的android:name。您不需要在其他活动中初始化片段 您可以在Google Play商店应用等其他活动中通过滑动访问导航抽屉
