如何在android studio的同一活动中实现导航抽屉和滑动标签? [英] How to impliment navigation drawer and swipe tab in same activity in android studio?

问题描述

我分别完成了这两项活动，我想将这两项活动合并为一项活动.我不知道我该怎么办.请帮帮我.

I have done both separately and I want to combine the both activity in single activity. I can't get any idea what should I do. Please please help me.

推荐答案

您可以轻松地将 NavigationView 与 ViewPager 集成在一起，分别用于导航菜单和启用 swype 的视图.示例实现是:

You can easily integrate a NavigationView along with ViewPager for navigation menu and swype-enabled views respectively. Example implementation would be:

Public class MainActivity extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener {

    private DrawerLayout mDrawerLayout;
    ...

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
        mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager());

        // Set up the ViewPager with the sections adapter.
        mViewPager = (ViewPager) findViewById(R.id.container);
        mViewPager.setAdapter(mSectionsPagerAdapter);

        // Set up the tabs for ViewPager
        TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs);
        tabLayout.setupWithViewPager(mViewPager);

        DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
        ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
                this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
        drawer.setDrawerListener(toggle);
        toggle.syncState();

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

    ...
    //Do other stuff like defining the viewpager, assigning navigation menu tasks, opening and closing the drawer etc etc

在你的布局中，确保布局看起来像:

And in your layout, make sure the layout looks something like:

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

    <LinearLayout
        android:id="@+id/content"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">

        <android.support.v7.widget.Toolbar
            android:id="@+id/toolBar"
            android:layout_width="match_parent"
            android:layout_height="wrap_content" />

        <android.support.design.widget.AppBarLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content">

            <android.support.design.widget.TabLayout
                android:id="@+id/tabLayout"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:elevation="5dp"
                android:background="@drawable/tablayout"
                app:theme="@style/ThemeOverlay.AppCompat.Dark"
                app:layout_scrollFlags="scroll|enterAlways"
                tools:ignore="UnusedAttribute" />

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

        <android.support.v4.view.ViewPager
            android:id="@+id/pager"
            android:layout_width="match_parent"
            android:layout_height="0dp"
            android:layout_weight="1">

        </android.support.v4.view.ViewPager>

    </LinearLayout>

    <android.support.design.widget.NavigationView
        android:id="@+id/navigation_view"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        app:menu="@menu/navigation_home"/>

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