android java - 在弹出对话框时动态更改基本适配器对话框中的数据

问题描述

当用户在网格视图中显示的回收器视图中点击文本视图年龄时，我想将一个人的年龄增加 10 岁。还有一个自定义对话框，显示相同的数据，当用户点击其中一张基本适配卡时会弹出这些数据。我还想在用户点击 textview age 而不关闭弹出对话框时更改对话框的数据。详情请见底部图片。

代码： MainActivity.java:

public class MainActivity extends AppCompatActivity {

    ActivityMainBinding binding;
    Context c;
    ArrayList<ListData> listData;
    ArrayList<ListDataDetails> listDataDetails;
    int[] arrayImages;
    MyAdapter adapter;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        binding = ActivityMainBinding.inflate(getLayoutInflater());
        setContentView(binding.getRoot());

        c = this;
        listData = new ArrayList<>();

        setupData();
        setupAdapter();
    }

    private void setupData() {

        arrayImages = new int[] {
                R.drawable.ic_launcher_background,R.drawable.ic_launcher_foreground,R.drawable.ic_launcher_background,R.drawable.ic_launcher_background
        };

        for (int i = 0; i < 5; i++) {

            listDataDetails = new ArrayList<>();
            if (i == 0) {

                listDataDetails.add(new ListDataDetails("0","Sabu","20","Kochi"));
                listData.add(new ListData("0","Painter","12000",listDataDetails));
            } else if (i == 1) {

                listDataDetails.add(new ListDataDetails("1","Thomas","30","Kottayam"));
                listData.add(new ListData("1","Carpenter","13000",listDataDetails));
            } else if (i == 2) {

                listDataDetails.add(new ListDataDetails("2","Anly","40","Tiruvalla"));
                listData.add(new ListData("2","Welder","15000",listDataDetails));
            } else if (i == 3) {

                listDataDetails.add(new ListDataDetails("3","Sebato","50","Fort Kochi"));
                listData.add(new ListData("3","Watch Man","10000",listDataDetails));
            } else {

                listDataDetails.add(new ListDataDetails("4","Angel","60","Aluva"));

图片：当用户点击 textview age 时，它应该增加 10 年的年龄

功能与第一张图片相同，但在更改值时不应关闭弹出窗口。
