I'；我正在使用Android Studio创建一个应用程序。我遇到的情况是我试图使用另一个活动中的图像

该应用程序的想法是通过记忆图像来解决这个问题。我已经完成了majoriti代码，但我遇到了一个情况，我试图使用另一个活动的图像

这是MainActivity的代码。我正在设置一个计时器来记忆给定的6个img的多边形

public class MainActivity extends AppCompatActivity {

    private TextView Text1;
    public ImageView imageView;
    public ImageView imageView2;
    public ImageView imageView3;
    public ImageView imageView4;
    public ImageView imageView5;
    public ImageView imageView6;
    Timer timer;

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

        imageView = findViewById(R.id.imageView);
        imageView2 = findViewById(R.id.imageView2);
        imageView3 = findViewById(R.id.imageView3);
        imageView4 = findViewById(R.id.imageView4);
        imageView5 = findViewById(R.id.imageView5);
        imageView6 = findViewById(R.id.imageView6);

        timer = new Timer();
        timer.schedule(new TimerTask() {
            @Override
            public void run() {
                Intent intent = new Intent(MainActivity.this, Question1.class);
                startActivity(intent);
                finish();
            }
        },5000);
    }
}

下面的代码是第二个活动。我正在尝试修复位于“imageView.setImageResource（getResources（）.getIdentifier（quick.get（0），“drawable”，getPackageName（））”的代码

公共类问题1扩展了AppCompative活动{
私人文本视图问题1；
专用按钮ans1、ans2、ans3、ans4、ans5、ans6、next；
私用字符串右键回答；
私人int右键\答案\计数；
私有整数quizCount=1；
ArrayList quizArray=新的ArrayList（）；
字符串quizData[][]{
{“七边形”、“三角形”、“四边形”、“五边形”、“六边形”、“十边形”}
};
@凌驾
创建时受保护的void（Bundle savedInstanceState）{
super.onCreate（savedInstanceState）；
setContentView（R.layout.activity_问题1）；
问题1=findViewById（R.id.Question1）；
ans1=findViewById（R.id.ans1）；
ans2=findViewById（R.id.ans2）；
ans3=findViewById（R.id.ans3）；
ans4=findViewById（R.id.ans4）；
ans5=findViewById（R.id.ans5）；
ans6=findViewById（R.id.ans6）；
next=findViewById（R.id.next）；
for（int i=0；i

因此，我不知道如何让第二个活动使用来自MainActivity的映像。

您可以将映像的资源ID作为一个额外的目的传递：

Owhh我已经研究了您给我的链接。它对我很有用！但是我有一个关于发送数据和接收数据的问题。它需要数据类型，但我不知道图像的类型。资源ID是int。您只能将某些数据类型作为intent extra传递，但int是其中之一。Owhh好的。我已经解决了我的问题。谢谢您或者你的回复

public class Question1 extends AppCompatActivity {

    private TextView Question1;
    private Button ans1, ans2, ans3, ans4, ans5, ans6, next;

    private String Right_Answer;
    private int Right_Answer_Count;
    private int quizCount = 1;

    ArrayList<ArrayList<String>> quizArray = new ArrayList<>();

    String quizData[][] = {
            {"heptagon","triangle","quadrilateral","pentagon","hexagon","decagon"}
    };

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_question1);

        Question1 = findViewById(R.id.Question1);
        ans1 = findViewById(R.id.ans1);
        ans2 = findViewById(R.id.ans2);
        ans3 = findViewById(R.id.ans3);
        ans4 = findViewById(R.id.ans4);
        ans5 = findViewById(R.id.ans5);
        ans6 = findViewById(R.id.ans6);
        next = findViewById(R.id.next);

        for (int i=0; i < quizData.length; i++){
            ArrayList<String> tmpArray = new ArrayList<>();
                tmpArray.add(quizData[i][0]);
