android - 查看寻呼机垂直重叠选项卡 fragment

Question

我正在使用 Viewpager 浏览选项卡。但是我的 viewpager 与 fragment 的顶部重叠，因此所有 fragment 的顶部都不可见。在顶部添加填充可以完成工作，但有没有比在下一个 View 上填充更好的方法。

布局

<?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"
       tools:context=".Activity.MainActivity">

<android.support.design.widget.AppBarLayout
   android:layout_width="match_parent"
   android:layout_height="wrap_content"
   android:fitsSystemWindows="true"
   android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">

   <android.support.design.widget.TabLayout
       android:layout_width="match_parent"
       android:layout_height="wrap_content"
       android:id="@+id/tabs">
   </android.support.design.widget.TabLayout>

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


<android.support.v4.view.ViewPager
    android:id="@+id/pager"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    android:background="#ffffff">

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

</RelativeLayout>

Activity

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

    // ActionBar

    final ActionBar actionBar = getSupportActionBar();
    actionBar.setDefaultDisplayHomeAsUpEnabled(true);


    // ViewPage: Slider that helps to create a page that we can swipe
    PagerAdapter pagerAdapter = new TabPagerAdapter(getSupportFragmentManager());
    ViewPager tab = (ViewPager) findViewById(R.id.pager);

    tab.setAdapter(pagerAdapter);

    //Tablayout : Shows the tab bar that helps to find the ViewPager page
    TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs);
    tabLayout.setupWithViewPager(tab);

}
