我从SOAP中提取了JSON字符串 我想在ListView中显示它 需要添加什么代码请建议他们没有命名的JSON对象
My Mainactivity.java
private static String SOAP_ACTION = "http://tempuri.org/METHOD_NAME";
private static String NAMESPACE = "http://tempuri.org/";
private static String METHOD_NAME = "METHOD_NAME";
private static String URL = "myurl.com";
Button button1;
TextView textView1;
String jsonStr;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
button1 =(Button) findViewById(R.id.idbutton1);
textView1 = (TextView) findViewById(R.id.idtxtView1);
button1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//Initialize soap request + add parameters
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
//Use this to add parameters
request.addProperty("id_no", 123
request.addProperty("serial_no", 2);
request.addProperty("Year", 2017);
request.addProperty("Username", "username");
request.addProperty("Password", "password");
//Declare the version of the SOAP request
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.setOutputSoapObject(request);
envelope.dotNet = true;
try {
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
//this is the actual part that will call the webservice
androidHttpTransport.call(SOAP_ACTION, envelope);
// Get the SoapResult from the envelope body.
SoapPrimitive resultsRequestSOAP = (SoapPrimitive) envelope.getResponse();
jsonStr = resultsRequestSOAP.toString();
textView1.setText(jsonStr);
} catch(Exception E) {
xy = ("ERROR:" + E.getClass().getName() + ": " + E.getMessage());
}
textView1.setText(jsonStr);
}
});
}
我的JSON字符串（来自web）是
[{"name":"ravi","idnumber":2,"surname":"bhosle","areaname":"pune","state":"maharashtra","country":"india","registrationfees":100},{"name":"amit","idnumber":2,"surname":"gayakwad","areaname":"nanded","state":"maharashtra","country":"india","registrationfees":80}]
使用item_list在activity_main中创建的listView 如何在该
中显示该JSON字符串答案 0 :(得分：0)
试试这个
try{
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
//this is the actual part that will call the webservice
androidHttpTransport.call(SOAP_ACTION, envelope);
// Get the SoapResult from the envelope body.
SoapPrimitive resultsRequestSOAP = (SoapPrimitive) envelope.getResponse();
JSONArray jarray = new JSONArray(resultsRequestSOAP );
JSONObject obj = new JSONObject();
System.out.println("jsonarraylength-->>"+jarray.length());
for(int i=0;i<jarray.length();i++){
obj = jarray.getJSONObject(i);
System.out.println(obj.getString("name"));
System.out.println(obj.getString("idnumber"));
}
}catch(Exception e){
e.printStackTrace();
}

删除了textView1.setText（jsonStr）; 并使用下面的代码
private static String SOAP_ACTION = "http://tempuri.org/METHOD_NAME";
private static String NAMESPACE = "http://tempuri.org/";
private static String METHOD_NAME = "METHOD_NAME";
private static String URL = "myurl.com";
Button button1;
TextView textView1;
String jsonStr;
ListView listView1 =(ListView) findViewById(R.id.idlistView1);
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
button1 =(Button) findViewById(R.id.idbutton1);
textView1 = (TextView) findViewById(R.id.idtxtView1);
button1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//Initialize soap request + add parameters
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
//Use this to add parameters
request.addProperty("id_no", 123
request.addProperty("serial_no", 2);
request.addProperty("Year", 2017);
request.addProperty("Username", "username");
request.addProperty("Password", "password");
//Declare the version of the SOAP request
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.setOutputSoapObject(request);
envelope.dotNet = true;
try {
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
//this is the actual part that will call the webservice
androidHttpTransport.call(SOAP_ACTION, envelope);
// Get the SoapResult from the envelope body.
SoapPrimitive resultsRequestSOAP = (SoapPrimitive) envelope.getResponse();
jsonStr = resultsRequestSOAP.toString();
textView1.setText(jsonStr);
} catch(Exception E) {
xy = ("ERROR:" + E.getClass().getName() + ": " + E.getMessage());
}
if (xy != null) {
try {
// JSONObject jsonObj = new JSONObject(xy);
// Getting JSON Array node
JSONArray contacts = new JSONArray(xy);
// looping through All Contacts
for (int i = 0; i < contacts.length(); i++) {
JSONObject c = contacts.getJSONObject(i);
String sroname = c.getString("name");
String docnumber = c.getString("idnumber");
String ariclename = c.getString("surname");
String areaname = c.getString("areaname");
String consideration_amt = c.getString("state");
String marketvalue = c.getString("country");
String stampdutypaid = c.getString("registrationfees");
// Phone node is JSON Object
// tmp hash map for single contact
HashMap<String, String> contact = new HashMap<>();
// adding each child node to HashMap key => value
contact.put("name","Name: "+ name);
contact.put("idnumber","Id Number: "+ idnumber);
contact.put("surname","Surname: "+ surname);
contact.put("areaname","Area Name: "+ areaname);
contact.put("state","State: "+ state);
contact.put("country","Country: "+ country);
contact.put("registrationfees","Registration Fees: "+ registrationfees);
// adding contact to contact list
docdetails.add(contact);
}
}
catch(JSONException e)
{
String error = ("Json parsing error: " + e.getMessage());
Toast.makeText(getApplicationContext(),error,Toast.LENGTH_LONG).show();
}
} else
{
String error = ("Couldn't get json from server. ");
Toast.makeText(getApplicationContext(),error,Toast.LENGTH_SHORT).show();
}
/**
* Updating parsed JSON data into ListView
* */
ListAdapter adapter = new SimpleAdapter(WebResponce.this, docdetails,R.layout.list_item, new String[]{"name","idnumber","surname","areaname","state","country","registrationfees"},
new int[]{R.id.idname,R.id.ididnumber,R.id.idsurname, R.id.idareaname,R.id.idstate,R.id.idcountry,R.id.idregistrationfees});
listView11.setAdapter(adapter);
}
});
}
