列表视图显示员工详细信息,我还尝试了表格布局,但我只能水平显示,但我希望他们在垂直布局中逐个显示。我不知道如何以垂直顺序显示它们,是否有可能以垂直顺序显示它们,
这是我的代码:

profile layout

    package com.example.myapplication;
import android.os.AsyncTask;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.Toast;

import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;

public class Profile extends AppCompatActivity {

    ListView listView;

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

        listView = (ListView) findViewById(R.id.listView);
        getJSON(Config_URLS.TAG_PROFILE);
    }


    private void getJSON(final String urlWebService) {

        class GetJSON extends AsyncTask<Void, Void, String> {

            @Override
            protected void onPreExecute() {
                super.onPreExecute();
            }


            @Override
            protected void onPostExecute(String s) {
                super.onPostExecute(s);
                Toast.makeText(getApplicationContext(), s, Toast.LENGTH_SHORT).show();
                try {
                    loadIntoListView(s);
                } catch (JSONException e) {
                    e.printStackTrace();
                }
            }

            @Override
            protected String doInBackground(Void... voids) {
                try {
                    URL url = new URL(urlWebService);
                    HttpURLConnection con = (HttpURLConnection) url.openConnection();
                    StringBuilder sb = new StringBuilder();
                    BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(con.getInputStream()));
                    String json;
                    while ((json = bufferedReader.readLine()) != null) {
                        sb.append(json + "\n");
                    }
                    return sb.toString().trim();
                } catch (Exception e) {
                    return null;
                }
            }
        }
        GetJSON getJSON = new GetJSON();
        getJSON.execute();
    }

    private void loadIntoListView(String json) throws JSONException {
        JSONArray jsonArray = new JSONArray(json);
        String[] profiledata = new String[jsonArray.length()];
        for (int i = 0; i < jsonArray.length(); i++) {
            JSONObject obj = jsonArray.getJSONObject(i);
            profiledata[i] = obj.getString("Profile_Data");
        }
        ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, profiledata);
        listView.setAdapter(arrayAdapter);
    }
}
这是我的json输出:

 {"Profile_Data":[{"StoreID":"22325","EmployeeId":"15","Cashier_name":"","Cashier_id":"0","Payroll_clockin":"","Employee_First_Name":"Damiana","Employee_Middle_Name":"","Employee_Last_Name":"Lobato","Color":null,"Sex":"male","Address":"1st","Email":"damiana_ala@hh.com","Cell":"2179356","City":"Sacramento","State":"CA","Pincode":"9999","Role":"Shiftlead","Status":"N","Basicpay":"0.00","Username":"rajesh","Password":"1995","Dateofhire":"0000-00-00","DateofTerm":null}]}
请任何人帮我找到这样的解决方案输出

StoreID: 22325
EmployeeId: 15

Listview从不放在scrollview中

您必须创建自定义适配器以查看listview中的项

它不工作bro,我想一个接一个地以垂直顺序显示它们是否有任何可能的解决方案?不使用/使用listviewsplit json对象到单个变量中,然后通过“\n”(断开字符串)附加到单个字符串中并放入适配器。bro您能为它发布任何示例代码吗,以便我能理解。
