保存编辑到listview android studio

我有一个列表视图的餐馆有4个不同的字符串：名称，地址，描述和标签 . 当我点击餐馆时它会引导我到我的 detailsActivity.java ，我让用户编辑名称，地址，描述和标签，然后用户可以保存编辑后的信息以存储在列表视图中 .

到目前为止，当我点击保存时，它只会保存名称的数据...地址，描述和标签字符串不会保存新信息 .

这是我的代码：

public class DetailsActivity extends AppCompatActivity {

    private int pos;
    //RATE RESTAURANT BUTTON
    RatingBar ratingbar1;
    Button button;


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

        Intent i = getIntent();
        String name = i.getStringExtra("name");
        final String address = i.getStringExtra("address");
        String description = i.getStringExtra("description");
        String tags = i.getStringExtra("tags");
        pos = i.getIntExtra("position", -1);        //-1 means not set

        EditText ename = findViewById(R.id.editName);
        EditText eaddress = findViewById(R.id.editAddress);
        EditText edescription = findViewById(R.id.editDescription);
        EditText etags = findViewById(R.id.editTags);
        ename.setText(name);
        eaddress.setText(address);
        edescription.setText(description);
        etags.setText(tags);

        findViewById(R.id.btnSave).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                Intent i = getIntent();
                EditText ename = findViewById(R.id.editName);
                EditText eaddress = findViewById(R.id.editAddress);
                EditText edescription = findViewById(R.id.editDescription);
                EditText etags = findViewById(R.id.editTags);

                String name = ename.getText().toString();
                String address = eaddress.getText().toString();
                String description = edescription.getText().toString();
                String tags = etags.getText().toString();

                i.putExtra("name", name);
                i.putExtra("address", address);
                i.putExtra("description", description);
                i.putExtra("tags", tags);
                i.putExtra("position", pos);

                setResult(RESULT_OK, i);
                finish();
            }
        });

以下是我的xml文件，以防需要它们：

这是listview所在的activity_main.xml：

最后是mainactivity.java，其中包含我的onActivityResult函数：

public class MainActivity extends AppCompatActivity {

    private ArrayList<Item> items;
    private ItemsAdapter itemsAdapter;
    private ListView lvItems;

    @Override
    protected void onCreate(Bundle savedInstanceState) {

        items = new ArrayList<>();
        items.add(new Item ("Mcdonalds", "108 queen st", "come get a junior chicken", "fast food"));
        items.add(new Item("Pizza Pizza", "9 moms st", "wonderful pizza made by mom", "pizza"));

        itemsAdapter = new ItemsAdapter(this, R.layout.row_layout, items);
        lvItems.setAdapter(itemsAdapter);

        Button btn = findViewById(R.id.button);
        btn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                //ADD NEW ITEM TO LIST
                EditText et = findViewById(R.id.editItem);
                String text = et.getText().toString();
                if(!text.isEmpty())
                {

                    et.setText("");
                }
            }
        });


        //ABOUT PAGE REDIRECT
        Button btn1 = findViewById(R.id.btnabout);
        btn1.setOnClickListener(new View.OnClickListener() {

                new AlertDialog.Builder(view.getContext()).setTitle("Warning!")
                        .setMessage("Do you want to remove this item?")
                        .setNegativeButton(android.R.string.no, null)
                        .setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() {
                            @Override

                return true;

            }
        });

        //ADD NEW LISTENER TO LIST
        lvItems.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

                Intent i = new Intent(view.getContext(), DetailsActivity.class);
                i.putExtra("position", position);
                i.putExtra("name", items.get(position).getName());
                i.putExtra("address", items.get(position).getAddress());

                startActivityForResult(i, EDIT_ITEM);

            }
        });

    }




    //DEFINE OUR CALL OF EDIT ITEM

    }
