android - TabHost(从 fragment 中隐藏 Tabhost)

Question

我有一个 tabhost，它位于我的主要 Activity (抽屉导航)中。
在每个选项卡中，我都有 ViewPager。
ViewPager 由不同的 Fragment 组成。
在这些 fragment 中，我必须隐藏/显示我的 TabHost。
但我不知道如何将 TabHost 从我的 Activity 传递到 fragment 。

 protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_navigation);
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);

    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);

    tabHost = (TabHost) findViewById(R.id.tabHost);
    tabHost.setup();
    tabHost.setOnTabChangedListener(this);
    setNewTab(this, tabHost, "tab1", R.string.textTabTitle1, R.drawable.icon_search, R.id.tab1);
    setNewTab(this, tabHost, "tab2", R.string.textTabTitle1, R.drawable.icon_comment, R.id.tab2);
    setNewTab(this, tabHost, "tab3", R.string.textTabTitle1, R.drawable.icon_car, R.id.tab3);


    final ViewPager pagerComment = (ViewPager) findViewById(R.id.pagerComment);
    pagerComment.setAdapter(new AdapterTabComment(getSupportFragmentManager()));

    final ViewPager pagerSearch = (ViewPager) findViewById(R.id.pagerSearch);
    pagerSearch.setAdapter(new AdapterTabSearch(getSupportFragmentManager()));

    tabsComment = (PagerSlidingTabStrip) findViewById(R.id.tabsComment);
    tabsComment.setViewPager(pagerComment);
    setTextColor(0, tabsComment);

    tabsSearch = (PagerSlidingTabStrip) findViewById(R.id.tabsSearch);
    tabsSearch.setViewPager(pagerSearch);
    setTextColor(0, tabsSearch);

    pagerComment.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
        @Override
        public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
        }

        @Override
        public void onPageSelected(int position) {
            setTextColor(position, tabsComment);
        }

        @Override
        public void onPageScrollStateChanged(int state) {
        }
    });


    pagerSearch.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
        @Override
        public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
        }

        @Override
        public void onPageSelected(int position) {
            setTextColor(position,tabsSearch);
        }

        @Override
        public void onPageScrollStateChanged(int state) {}});
    pagerSearch.setCurrentItem(0);
}

这可能吗？
谢谢..

您可以将 TabHost 声明为静态的，并且可以在您的 fragment 中访问。我在我的项目中使用了它。
