java - 如何在每个 Activity 中显示滑动菜单栏？

Question

我正在制作一个带有滑动菜单的 Android 应用程序，但我希望它可用于所有 Activity 。

这是我的问题的一个示例:我有 7 个主要选项(主页、翻译器、游览、设置等)，名为fragment1 到fragment7，但我在 Tour 中也有一个水平 ScrollView 和其他 Activity ，我希望这些“其他 Activity ”也显示滑动菜单..

这是我的代码

Answer 1

解决了!对于任何其他想要将 TabHost 添加到 Fragment 中的人，这就是我所做的..

不要忘记导入抽屉导航中包含的所有 fragment

MainActivity.java

DrawerLayout drawerLayout;
RelativeLayout drawerPane;
ListView lvNav;

List<NavItem> listNavItems;
List<Fragment> listFragments;

ActionBarDrawerToggle actionBarDrawerToggle;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    getSupportActionBar().setDisplayHomeAsUpEnabled(true);

    drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
    drawerPane = (RelativeLayout) findViewById(R.id.drawer_pane);
    lvNav = (ListView) findViewById(R.id.nav_list);

    listNavItems = new ArrayList<NavItem>();
    listNavItems.add(new NavItem("Home", "MyHome page",
            R.drawable.ic_action_home));
    listNavItems.add(new NavItem("Translator", "English Cebuano",
            R.drawable.ic_action_home));
    listNavItems.add(new NavItem("Settings", "Change something",
            R.drawable.ic_action_settings));
    listNavItems.add(new NavItem("About", "Author's information",
            R.drawable.ic_action_about));

    NavListAdapter navListAdapter = new NavListAdapter(
            getApplicationContext(), R.layout.item_nav_list, listNavItems);

    lvNav.setAdapter(navListAdapter);

    listFragments = new ArrayList<Fragment>();
    listFragments.add(new MyHome());
    listFragments.add(new MyTrans());
    listFragments.add(new MySettings());
    listFragments.add(new MyAbout());

    // load first fragment as default:
    FragmentManager fragmentManager = getSupportFragmentManager();
    fragmentManager.beginTransaction()
            .replace(R.id.main_content, listFragments.get(0)).commit();

    setTitle(listNavItems.get(0).getTitle());
    lvNav.setItemChecked(0, true);
    drawerLayout.closeDrawer(drawerPane);

    // set listener for navigation items:
    lvNav.setOnItemClickListener(new OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view,
                                int position, long id) {

            // replace the fragment with the selection correspondingly:
            FragmentManager fragmentManager = getSupportFragmentManager();
            fragmentManager
                    .beginTransaction()
                    .replace(R.id.main_content, listFragments.get(position))
                    .commit();

            setTitle(listNavItems.get(position).getTitle());
            lvNav.setItemChecked(position, true);
            drawerLayout.closeDrawer(drawerPane);

        }
    });

    // create listener for drawer layout
    actionBarDrawerToggle = new ActionBarDrawerToggle(this, drawerLayout,
            R.string.drawer_opened, R.string.drawer_closed) {

        @Override
        public void onDrawerOpened(View drawerView) {
            // TODO Auto-generated method stub
            invalidateOptionsMenu();
            super.onDrawerOpened(drawerView);
        }

        @Override
        public void onDrawerClosed(View drawerView) {
            // TODO Auto-generated method stub
            invalidateOptionsMenu();
            super.onDrawerClosed(drawerView);
        }

    };

    drawerLayout.setDrawerListener(actionBarDrawerToggle);

}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.

    getMenuInflater().inflate(R.menu.menu_main, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the MyHome/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    if (actionBarDrawerToggle.onOptionsItemSelected(item))
        return true;

    return super.onOptionsItemSelected(item);
}

@Override
protected void onPostCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onPostCreate(savedInstanceState);
    actionBarDrawerToggle.syncState();
}

接下来是我出错的地方，直接将TabHost导入到fragment.java类中，以及onpagelistener(扩展Fragment实现了OnTabChangeListener)

MyTrans.java

    OnPageChangeListener {

private TabHost tabHost;
private ViewPager viewPager;
private MyFragmentPagerAdapter myViewPagerAdapter;
int i = 0;
View v;

@Override
public View onCreateView(LayoutInflater inflater,
                         @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {

    v = inflater.inflate(R.layout.tabs_viewpager_layout, container, false);



    i++;

    // init tabhost
    this.initializeTabHost(savedInstanceState);

    // init ViewPager
    this.initializeViewPager();


    return v;
}

// fake content for tabhost
class FakeContent implements TabContentFactory {
    private final Context mContext;

    public FakeContent(Context context) {
        mContext = context;
    }

    @Override
    public View createTabContent(String tag) {
        View v = new View(mContext);
        v.setMinimumHeight(0);
        v.setMinimumWidth(0);
        return v;
    }
}

private void initializeViewPager() {
    List<Fragment> fragments = new Vector<Fragment>();

    fragments.add(new Tab1Fragment());
    fragments.add(new Tab2Fragment());
    fragments.add(new Tab3Fragment());

    this.myViewPagerAdapter = new MyFragmentPagerAdapter(
            getChildFragmentManager(), fragments);
    this.viewPager = (ViewPager) v.findViewById(R.id.viewPager);
    this.viewPager.setAdapter(this.myViewPagerAdapter);
    this.viewPager.setOnPageChangeListener(this);

}

private void initializeTabHost(Bundle args) {

    tabHost = (TabHost) v.findViewById(android.R.id.tabhost);
    tabHost.setup();

    for (int i = 1; i <= 3; i++) {

        TabHost.TabSpec tabSpec;
        tabSpec = tabHost.newTabSpec("Tab " + i);
        tabSpec.setIndicator("Tab " + i);
        tabSpec.setContent(new FakeContent(getActivity()));
        tabHost.addTab(tabSpec);
    }
    tabHost.setOnTabChangedListener(this);
}

@Override
public void onTabChanged(String tabId) {
    int pos = this.tabHost.getCurrentTab();
    this.viewPager.setCurrentItem(pos);

    HorizontalScrollView hScrollView = (HorizontalScrollView) v
            .findViewById(R.id.hScrollView);
    View tabView = tabHost.getCurrentTabView();
    int scrollPos = tabView.getLeft()
            - (hScrollView.getWidth() - tabView.getWidth()) / 2;
    hScrollView.smoothScrollTo(scrollPos, 0);

}

@Override
public void onPageScrollStateChanged(int arg0) {
}

@Override
public void onPageScrolled(int arg0, float arg1, int arg2) {
}

@Override
public void onPageSelected(int position) {
    this.tabHost.setCurrentTab(position);
}

接下来，使用 inflater 为您的选项卡创建类，具体取决于您需要的数量

@Override
public View onCreateView(LayoutInflater inflater,
        @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {

    View v = inflater.inflate(R.layout.tab1fragment, container, false);

    return v;
}

然后你必须制作一个layout.xml文件来实现scrollview、大小等

tabs_viewpager_layout.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <TabHost
        android:id="@android:id/tabhost"
        android:layout_width="match_parent"
        android:layout_height="match_parent" >

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:orientation="vertical" >

            <HorizontalScrollView
                android:id="@+id/hScrollView"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:fillViewport="true"
                android:scrollbars="none" >

                <TabWidget
                    android:id="@android:id/tabs"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content" >
                </TabWidget>
            </HorizontalScrollView>

            <FrameLayout
                android:id="@android:id/tabcontent"
                android:layout_width="match_parent"
                android:layout_height="match_parent" >

                <android.support.v4.view.ViewPager
                    android:id="@+id/viewPager"
                    android:layout_width="match_parent"
                    android:layout_height="match_parent" />
            </FrameLayout>
        </LinearLayout>
    </TabHost>

</LinearLayout>

接下来，为每个选项卡创建一个 .xml

tab1fragment.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textSize="20sp"
        android:text="Fragment 1" />

最后，不要忘记为每个抽屉导航创建一个 .xml 文件(当然..)

fragment_tour.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Tour"
        android:textColor="#000"
        android:textSize="18sp"
        android:textStyle="bold" />

</LinearLayout>

所以基本上，在您想要的 fragment 中制作 tabhost <,<现在听起来很简单..

祝大家新年快乐。
