我正在开发一个项目，该项目要求SlidingTabLayout选项卡中的ListViews填充数据，但是，当我启动程序时，列表不会出现。我已经调试过以确保数据实际发送到那里，这完全发生了。
活动本身的xml：
<LinearLayout 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"
android:orientation="vertical"
tools:context=".MainActivity">
<include
android:id="@+id/tool_bar"
layout="@layout/tool_bar"
android:layout_height="wrap_content"
android:layout_width="match_parent"
/>
<com.example.jafeth.wearnote.SlidingTabLayout
android:id="@+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:elevation="2dp"
android:background="@color/ColorPrimary"/>
<android.support.v4.view.ViewPager
android:id="@+id/pager"
android:layout_height="match_parent"
android:layout_width="match_parent"
android:layout_weight="1"
></android.support.v4.view.ViewPager>
标签的xml：
<android.support.v4.widget.SwipeRefreshLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/swiperefresh1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin"
tools:context="com.example.jafeth.wearnote.ZabbixActivity">
<ListView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/listView1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_above="@+id/errorTextView" />

任何人都可以帮我找到让ListViews再次出现的方法吗？
