ConstraintLayout 按钮离开屏幕

Question

我的ConstraintLayout在我的手机上使用时可以正常工作，但在我朋友的手机上，某些按钮不会显示在屏幕上。

我将如何解决这个问题？

是否可以将其转换为其他类型的布局，而不必重新设计所有内容？

这是我当前的代码：

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

    <AutoCompleteTextView
        android:id="@+id/clubname"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_marginStart="96dp"
        android:layout_marginEnd="102dp"
        android:layout_marginBottom="36dp"
        android:gravity="center"
        android:hint="@string/club_name"
        app:layout_constraintBottom_toTopOf="@+id/EditDate"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintHorizontal_bias="0.5"
        app:layout_constraintStart_toStartOf="parent" />

    <Button
        android:id="@+id/EditDate"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_marginStart="96dp"
        android:layout_marginTop="285dp"
        android:layout_marginEnd="102dp"
        app:layout_constraintHeight_percent="0.1"
        app:layout_constraintWidth_percent="0.3"
        android:ems="10"
        android:gravity="center"
        android:hint="@string/date_button"
        android:onClick="sendButton"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintHorizontal_bias="0.5"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

    <Spinner
        android:id="@+id/eventName"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_marginStart="100dp"
        android:layout_marginTop="44dp"
        android:layout_marginEnd="102dp"
        android:ems="10"
        android:gravity="center"
        android:visibility="visible"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintHorizontal_bias="1.0"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toBottomOf="@+id/EditDate" />


    <Button
        android:id="@+id/button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginTop="104dp"
        android:onClick="sendButton"
        android:text="@string/send"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintHorizontal_bias="0.498"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toBottomOf="@+id/eventName" />

</androidx.constraintlayout.widget.ConstraintLayout>

删除EditDate的硬编码上边距，并使用app:layout_constraintBottom_toBottomOf="parent"在父级中垂直居中

还要将app:layout_constraintBottom_toBottomOf="parent"添加到底部button ，这样您就可以确保它不会超出屏幕底部。
