Java 如何在android中的元素上显示

我正在按照一个教程制作tic-tac-toe游戏，我希望当用户赢得游戏时，我的图像弹出并显示在所有其他背景图像上。图像弹出并显示游戏获胜，图像覆盖所有其他元素。相反，元素显示在图像上

//用于显示图像的弹出窗口
//弹出窗口的结尾

有两种方法可以做到这一点

1）将您的奖杯布局作为

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"
        xmlns:tools="http://schemas.android.com/tools"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        tools:context=".MainActivity">
    
    
        <GridLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:background="#a00">
            <!--Your Views-->
        </GridLayout>
    
        <RelativeLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:background="#FF018786"
            android:gravity="center"
            app:layout_constraintBottom_toBottomOf="parent"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintTop_toTopOf="parent">
    
            <ImageView
                android:id="@+id/imageView"
                android:layout_width="80dp"
                android:layout_height="80dp"
                app:srcCompat="@drawable/trophy_istock" />
        </RelativeLayout>
    
    
    </androidx.constraintlayout.widget.ConstraintLayout>

由于某种原因，我们无法看到该图像，您能再次尝试上载它吗？
