所以在我的 Android 应用程序中，主要 Activity 有选项卡，每个选项卡中都有一个包含 ListView 的 fragment 。但由于某种原因， ListView 中的最后一项总是被切断。我四处寻找解决方案，但我还没有找到任何解决方案。有什么建议吗？
主要 Activity 布局
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/rl"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:layout_scrollFlags="scroll|enterAlways"
app:popupTheme="@style/ThemeOverlay.AppCompat.Light" />
<android.support.design.widget.TabLayout
android:id="@+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabMode="fixed"
app:tabGravity="fill"/>
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="@+id/viewpager"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior" />
</android.support.design.widget.CoordinatorLayout>
带有 ListView 的 fragment
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<ProgressBar
android:id="@+id/progressBar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
style="@style/Widget.AppCompat.ProgressBar" />
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">
<ListView
android:id="@+id/list"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
style="@style/Widget.AppCompat.ProgressBar"></ListView>
</LinearLayout>
</RelativeLayout>
列表项布局
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="2dp"
android:layout_margin="5dp">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="New Text"
android:id="@+id/title"
android:textSize="20sp"
android:textStyle="bold"
android:typeface="normal"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true" />
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="New Text"
android:id="@+id/author"
android:textSize="15sp"
android:typeface="normal"
android:layout_below="@+id/publishdate"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true" />
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="New Text"
android:id="@+id/publishdate"
android:textSize="15sp"
android:typeface="normal"
android:layout_below="@+id/title"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true" />
</LinearLayout>

最佳答案
将类似 android:paddingBottom="20dp" 的行放入 Fragment XML 文件中的 ListView 项目中。调整 20dp 值，直到它看起来像您想要的那样。
由于某些奇怪的原因，它只是解决了问题，并且与正在更改的 ListView 的大小无关。不知何故，小填充迫使 ListView 以不同的方式布局。
