android 文本视图被堆叠

我试图使用java在android studio上构建一个类似火种的功能。每个幻灯片都有一个视频（可以播放）和一些代表用户姓名，年龄等的TextViews。然而，除了最后一张幻灯片外，所有幻灯片上的TextViews都在堆叠。
查看除最后一张幻灯片外的所有幻灯片上的文本视图的外观：

的数据
有什么不对吗？
这是我的模型：

public class Person {

    private String videoLink;
    private String place;
    private String name;
    private String payment;
    private String age;

    public Person(String videoLink, String place, String name, String payment, String age) {
        this.videoLink = videoLink;
        this.place = place;
        this.name = name;
        this.payment = payment;
        this.age = age;
    }

    public String getPlace(){
        return place;
    }

    public String getName() {
        return name;
    }

    public String getAge() {
        return age;
    }

    public String getPayment() {
        return payment;
    }

    public String getVideoLink() {
        return videoLink;
    }
}

item.xml没有背景，这就是为什么你可以看到后面的其他TextView。
请尝试将android:background="@android:color/white"（或您喜欢的任何背景）指定为item.xml的根

使用约束布局，调整您的布局，因为你喜欢给填充，边距和你想要的颜色

<androidx.constraintlayout.widget.ConstraintLayout
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">

<FrameLayout
    android:id="@+id/videoContainer"
    android:layout_width="match_parent"
    android:layout_height="337dp"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent">

    <VideoView
        android:id="@+id/videoView"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

</FrameLayout>

<!-- TextViews outside the video FrameLayout -->
<TextView
    android:id="@+id/textViewName"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_below="@id/videoContainer"
    android:text="TextView2"
    android:textColor="@color/black"
    android:textSize="20sp"
    app:layout_constraintTop_toBottomOf="@+id/videoContainer" />

<TextView
    android:id="@+id/textViewAddress"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_below="@id/textViewName"
    android:text="TextView3"
    android:textColor="@color/black"
