如何向现有应用程序添加导航抽屉？

Question

我是制作应用程序的新手，我正在从事这个需要帮助的大学项目，我想为我的应用程序创建一个导航抽屉，但我不知道如何，我已经创建了登录，在我的应用程序中注册、编辑个人资料和主页，但现在我想在不创建全新项目的情况下为其添加导航抽屉，例如，我希望主页具有该抽屉，它将包含“编辑个人资料”等我可以从中进行不同的活动，我看过很多视频但还不太了解，因为它们都在制作新项目，我如何将我的所有活动链接到它而不需要创建新项目？ main_activity 代码

</androidx.constraintlayout.widget.ConstraintLayout>

<com.google.android.material.navigation.NavigationView
        android:id="@+id/navigationView"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:fitsSystemWindows="true"
        app:headerLayout="@layout/nav_header"
        app:menu="@menu/nav_menu" />
</androidx.drawerlayout.widget.DrawerLayout>

接下来，我们将在 layout 资源目录中为 Navigation Drawer Header 布局创建 nav_header.xml 布局文件。

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="150dp"
    android:gravity="bottom"
    android:orientation="vertical"
    android:padding="8dp"
    android:theme="@style/ThemeOverlay.AppCompat.Dark">


    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:paddingTop="8dp"
        android:text="Nav Drawer Text"
        android:textAppearance="@style/TextAppearance.AppCompat.Body1"
        android:textColor="@android:color/black" />

</LinearLayout>

我们还需要在menu资源目录下创建一个菜单。

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <item
        android:id="@+id/nav_call"
        android:title="Call" />
    <item
        android:id="@+id/nav_message"
        android:title="Message" />
    <item
        android:id="@+id/nav_history"
        android:title="History" />
    <item
        android:id="@+id/nav_view"
        android:title="View contact" />
    <item
        android:id="@+id/nav_edit"
        android:title="Edit contact" />
    <item
        android:id="@+id/nav_logout"
        android:title="Log out" />
</menu>

转到 MainActivity.java 并添加以下内容。

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.nav_activity_main);
        phone = findViewById(R.id.profilePhone);
        fullName = findViewById(R.id.profileName);
        email    = findViewById(R.id.profileEmail);
        resetPassLocal = findViewById(R.id.resetPasswordLocal);

        //You need a toolbar here. Create your own or use the Theme's one.
        setSupportActionBar(toolbar);

        DrawerLayout drawer = findViewById(R.id.drawer);
        NavigationView navigationView = findViewById(R.id.navigationView);

       ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
                this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
       drawer.setDrawerListener(toggle);
       toggle.syncState();
       navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
        @Override
        public boolean onNavigationItemSelected(MenuItem item) {
            if(item.getItemId() == R.id.nav_call)
                Toast.makeText(getApplicationContext(),"Hello",Toast.LENGTH_SHORT).show();
            //Do this for the rest of the navigation menu items.
            return true;
        }
    });
}

转到您的 strings.xml 资源文件并添加以下内容

<string name="navigation_drawer_open">Drawer Open</string>
<string name="navigation_drawer_close">Drawer Closed</string>

我想我们已经完成了。
