Question

我正在TabLayout使用PageViewer，但Tabs没有填充整个TabLayout。

在xml中，设置GRAVITY_FILL和MODE_FIXED是不够的，但设置

android.support.design:tabMaxWidth=0dp

将解决问题。

但是，由于TabLayout.setupWithViewPager(ViewPager)会覆盖TabLayout的{{1}}，因此我会以编程方式设置标签。

现在TabLayout.Tab没有均匀显示....有人可以帮忙吗？

TabLayout.xml

TabItem

MyActivity.java

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    tools:showIn="@layout/activity_main">
    <android.support.design.widget.TabLayout
            android:id="@+id/tab_layout"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:layout_gravity="top"
            app:tabGravity="fill"
            app:tabIndicatorColor="@color/tab_selected_text_color"
            app:tabMode="fixed"
            app:tabMaxWidth="0dp"> <!--this makes tabitem text filled evenly-->
        </android.support.design.widget.TabLayout>

    <android.support.v4.view.ViewPager xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/fragment_list_pager"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_below="@id/tab_layout"
        app:layout_behavior="@string/appbar_scrolling_view_behavior">
    </android.support.v4.view.ViewPager> <!--not overlapping with appbar-->


    <android.support.design.widget.FloatingActionButton
        android:id="@+id/fab"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_margin="@dimen/fab_margin"
        android:elevation="@dimen/shadow"
        android:tint="@android:color/background_light"
        android:layout_alignParentEnd="true"
        android:layout_alignParentRight="true"
        android:layout_alignParentBottom="true"
        app:srcCompat="@android:drawable/ic_input_add"
        tools:ignore="UnusedAttribute"
        tools:targetApi="lollipop" />

</RelativeLayout>

的gradle：

 ViewPager viewPager = (ViewPager) findViewById(R.id.fragment_list_pager);
        FragmentPagerAdapter adapter = new ReminderFragmentPagerAdapter(getSupportFragmentManager(), fragments);
        viewPager.setAdapter(adapter);

        viewPager.addOnPageChangeListener(new MyOnPageChangeListener()); 
        TabLayout tabLayout = (TabLayout) findViewById(R.id.tab_layout);
        tabLayout.setupWithViewPager(viewPager,true);//needs to be called before addTab, overrides TabTitle


        LayoutInflater inflater = LayoutInflater.from(this);

        for(int i =0; i<titles.length; i++){
            View tabCustomView = inflater.inflate(R.layout.tab_title_layout,null);
            tabLayout.addTab(tabLayout.newTab().setCustomView(tabCustomView), i);

            tabLayout.setTabMode(TabLayout.MODE_FIXED);
            tabLayout.setTabGravity(TabLayout.GRAVITY_FILL);
        }

    }

更新这个问题今天早些时候发生了，我搜索了这么多，但没有修复。刚才......

更改：

在TabLayout中添加TabItem（尽管根据官方网站他们只是占位符而且没有真正添加;
使用compile "com.android.support:appcompat-v7:26.1.0" Tab t = TabLayout.getTab;

所以在TabLayout.xml中

t.setCustomView(v);

<android.support.design.widget.TabLayout
    android:id="@+id/tab_layout"
    android:layout_width="match_parent"
    android:layout_height="?attr/actionBarSize"
    android:layout_gravity="top"
    app:tabGravity="fill"
    app:tabIndicatorColor="@color/tab_selected_text_color"
    app:tabMode="fixed"
    app:tabMaxWidth="0dp"> <!--this makes tabitem text filled evenly-->

    <!--TabItem are just view holders and not actually added to TabLayout-->
    <!--overridden by viewPagerAdapter.getPageTitle()-->
    <android.support.design.widget.TabItem
        android:id="@+id/tabItemList"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@drawable/tab_color_selector"/>

    <android.support.design.widget.TabItem
        android:id="@+id/tabItemMap"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@drawable/tab_color_selector" />
</android.support.design.widget.TabLayout>

这为我解决了问题。谢谢你们！
