不幸的是,没有回答关于如何隐藏Tab的问题android.support.design.widget.TabLayout.其他问题都是用的TabHost,我不想改变我的代码.

我想隐藏"三个"标签.

分段:

viewPager = (ViewPager) rootView.findViewById(R.id.search_viewPager);
viewPager.addOnPageChangeListener(viewPagerListener);
viewPager.setAdapter(adapter);
tabLayout = (TabLayout) rootView.findViewById(R.id.search_tabs);
tabLayout.setTabGravity(TabLayout.GRAVITY_FILL);
tabLayout.setupWithViewPager(viewPager);

布局:

<?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="match_parent"
android:background="@color/white"
android:orientation="vertical">

    <android.support.design.widget.TabLayout
    android:id="@+id/search_tabs"
    style="@style/TabLayoutStyle"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@color/white"
    android:elevation="1dp" />

    <android.support.v4.view.ViewPager
    android:id="@+id/search_viewPager"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true" />

</LinearLayout>

Answer 1

 //To hide the first tab 
 ((ViewGroup) tabLayout.getChildAt(0)).getChildAt(0).setVisibility(View.GONE);
 //Set the next  tab as selected tab
 TabLayout.Tab tab = tabLayout.getTabAt(1);
 tab.select(); 

Answer 2

您可以通过访问 TabLayout 的 TabViewtablayout.getTabAt(int index)并将其强制转换，LinearLayout以便将其可见性设置为 GONE

((LinearLayout) tabLayout.getTabAt(0).view).setVisibility(View.GONE);
