尝试使用 ConstraintLayout

Try this using ConstraintLayout

<?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"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <ImageView
        android:id="@+id/imgOne"
        android:layout_width="0dp"
        android:layout_height="0dp"
        android:background="@color/colorPrimary"
        app:layout_constraintBottom_toTopOf="@+id/imgThree"
        app:layout_constraintEnd_toStartOf="@id/imgTwo"
        app:layout_constraintHorizontal_bias="0.5"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

    <TextView
