我的片段未填满整个屏幕

Question

我创建了注册并在片段中签名，但是在大屏幕中，它没有填满屏幕；在小屏幕中，它滑出了。

这里是有关在大屏幕和小屏幕上的外观的图像。

我的res文件夹目录结构。

大屏幕：

小屏幕：

这是下面的xml文件：

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout 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"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    tools:context=".SignInFragment"
    android:background="@color/colorPrimaryDark">

    <androidx.constraintlayout.widget.ConstraintLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <ImageButton
            .../>

        <ImageView
            ... />

        <EditText
            ... />

        <EditText
            ... />

        <TextView
            ... />

        <Button
            .... />

        <TextView
            .../>

        <TextView
            ... />

        <View
            ... />

        <View
            ..."/>


    </androidx.constraintlayout.widget.ConstraintLayout>

</FrameLayout>

您应该将项目放置在线性布局中，并将其重力设置为'中心'
