如何在Activity1中显示用户在Activity 2 imageview2中选择的相同imageview1？

<ImageView
    android:id="@+id/imageView1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/placeholder_image" />

public class Activity1 extends AppCompatActivity {
    private ImageView imageView1;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_activity1);

        imageView1 = findViewById(R.id.imageView1);

        // 接收来自Activity2的数据
        Intent intent = getIntent();
        if (intent != null) {
            int selectedImage = intent.getIntExtra("selectedImage", R.drawable.placeholder_image);
            imageView1.setImageResource(selectedImage);
        }
    }
}

public class Activity2 extends AppCompatActivity {
    private ImageView imageView2;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_activity2);

        imageView2 = findViewById(R.id.imageView2);

        // 用户选择了图片并点击确认按钮
        imageView2.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // 获取用户选择的图片信息
                int selectedImage = R.drawable.selected_image;

                // 将选中的图片信息传递给Activity1
                Intent intent = new Intent(Activity2.this, Activity1.class);
                intent.putExtra("selectedImage", selectedImage);
                startActivity(intent);
            }
        });
    }
}
