I am very new in android.I my app I retrieve data from mysql database to list view. In my database table has a status column I also retrieve that value but I can not save into a variable. my concept to save status is if status value=0 a green image show side of that row.when status value change that colour will change.

Right side of each row have a image view with different colour. According to status value colour show.please help me.
You can simply do it like below
inside your getView()
ClientBookingData m = Items.get(position);
if(m.getStatus()==0)
//Your code to set Image Background
else
//Your code to set Image Background

I am getting org.json.JSONException: Value
at org.json.JSON.typeMismatch(JSON.java:111)
I hope you understand problem, I am still in learning stage so please give brief answer so that i can understand.
You are getting JSONArray from Response and trying to hold on JSONObject which causes org.json.JSONException: Value at org.json.JSON.typeMismatch(JSON.java:111) error
Try this
try {
JSONArray jsonArrayLST = new JSONArray(s);
for (int i = 0; i < jsonArrayLST.length(); i++) {
JSONObject contactObject= jsonArrayLST.getJSONObject(i);
String titleValue = contactObject.getString("title");
Integer pledgedValue = contactObject.getInt("amt.pledged");
Integer backersValue = contactObject.getInt("num.backers");
Project project = new Project();
project.setPleadges(pledgedValue);
project.setBackers(backersValue);
project.settitle(titleValue);
projects.add(project);
Log.v("Object details : " , " : " + pledgedValue + " : " + backersValue);
}
} catch (JSONException e) {
e.printStackTrace();
}
Also, you need to change in your adapter while setting item to textview, because your are setting int value which causes you android.content.res.Resources$NotFoundException: String resource ID error
pleadge.setText(String.valueOf(mList.get(position).getPleadges()));
backers.setText(String.valueOf(mList.get(position).getBackers()));

For this i also add adapter as well as arraylist.
but when i run this application api is not called perfectly..
hope anyone a]can help me..
here i add adapter and arraylist
Adapter
public Doctortype_Adapter(Context context, ArrayList<Doctortype_method> objects) {
super(context, R.layout.list_doctortype, objects);
this.context = context;
this.vi = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
this.actorList = objects;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
// convert view = design
//View v = convertView;
View rowView;
ViewHolder vh;
if (convertView == null) {
rowView = vi.inflate(R.layout.list_doctortype, null);
setViewHolder(rowView);
} else {
rowView = convertView;
}
vh = (ViewHolder) rowView.getTag();
vh.title.setText(Html.fromHtml(actorList.get(position).gettitle()));
vh.subtitle.setText(Html.fromHtml(actorList.get(position).getsubtitle()));
/* String image=actorList.get(position).getid();
UrlImageViewHelper.setUrlDrawable(vh.dimage, image.toString(), R.drawable.no_img);*/
return rowView;
}
static class ViewHolder {
public TextView title, subtitle;
}
private void setViewHolder(View rowView) {
ViewHolder vh = new ViewHolder();
vh.title = (TextView) rowView.findViewById(R.id.tvProfileName);
vh.subtitle = (TextView) rowView.findViewById(R.id.tvDesc);
}
}
arraylist
public Doctortype_method( String title, String subtitle) {
super();
this.title = title;
this.subtitle = subtitle;
}
public String gettitle() {
return title;
}
public void settitle(String title) {
this.title = title;
}
public String getsubtitle()
{
return subtitle;
}
public void setsubtitle(String subtitle) {
this.subtitle = subtitle;
}
there is no error but when i run this code api is not called and i didnt get the output i want.
Thnx in advance..
if (status.equalsIgnoreCase("true")) is wrong because you getting status:1 so it is if (status.equalsIgnoreCase("1")) try this and then change this array = jobj.getJSONArray("response"); to array = jobj.getJSONArray("data"); your JSONArray key is "data"
And replace this also
actorsList.add(new Doctortype_method(jsonChildNode.optString("State id"),jsonChildNode.optString("State name")));
with
actorsList.add(new Doctortype_method(jsonChildNode.optString("countryID"),jsonChildNode.optString("vCountry")));
hope this helps. if this doesn't help feel free to ask
EDIT:
I cant understand what you want but have a look at this
-> you need to create baseAdapter for listview and set that adapter into the listview with your arraylist
FOR FETCHING YOUR ABOVE DATA YOU NEED TO DO BELOW CODE:
String data;//your entire JSON data as String
try {
JSONObject object = new JSONObject(data);
String status = object.getString("status");
JSONArray dataArray = object.getJSONArray("data");
for (int i = 0; i < dataArray.length(); i++) {
JSONObject json1 = dataArray.getJSONObject(i);
String countryID = json1.getString("countryID");
String vCountry = json1.getString("vCountry");
}
} catch (JSONException e) {
e.printStackTrace();
}
Now if you want to show this vCountry in listview you have to add vCountry in ArrayList and then in listview.setAdapter you have to pass this ArrayList which is filled by vCountry. Hope you understand now. If you want adapter and listview code please check this link http://www.vogella.com/tutorials/AndroidListView/article.html
Finally i got the right answer.
May anyone get help from this in future.

I have an app that connects to server sends sql request and get JSON answer as JsonArray.
Its Asynktask in seperate class (HTTPRequest.java is my AsyncTask class, Responce.java its my callback interface class) and it works correct.
when I use it in OrderActivity.java like below
#Override //my interface class function
public void onPostExecute(JSONArray Result) {
load(Result);
}
private void load(JSONArray json) {
for(int i=0;i<json.length();i++){
try {
JSONObject jo = json.getJSONObject(i);
Product p = new Product(
jo.getInt("ID"),
jo.getInt("parent"),
jo.getInt("category"),
jo.getString("Item"),
jo.getDouble("Price")
);
products.add(p);
} catch (JSONException e) {
e.printStackTrace();
}
}
it does work and fills product with data, but when I assign to my class variable JSONArray json

I use listview in main layout and there is 6 textview in layouttumısler. I use IsAdapter in onPostExecute in myAsyncTask but when I execute the app it is stopped.
The mssql records come from web service truely, But I can not list. I take error in IsAdapter getView, in
tvUrunId.setText(is.getId());
please help me...
I made a bad mistake, when I change
public int getId() {return urunId;}
as
public String getId()
{
String s = Integer.toString(urunId);
return s;
}
the code works.
There is a gridview in which I want to display a image. I want to use this json below to diplay image in my gridview. I have an ImageAdapter class in ImageAdapter class I have AsynTask that get json but I don't know how to using it to diplaly image in gridview.

This example may help you
It is one of the sample example
void MainWindow_Loaded(object sender, RoutedEventArgs e)
{
HttpWebRequest myReq = (HttpWebRequest)WebRequest.Create("(link for fetching json data)");
myReq.Method = WebRequestMethods.Http.Get;
myReq.Accept = "apllication/json";
var response = (HttpWebResponse)myReq.GetResponse();
string myString= response.GetResponseHeader("Registration_Status");
using (var sr = new StreamReader(response.GetResponseStream()))
{
json = sr.ReadToEnd();
StreamWriter sw = new StreamWriter(#"D:\others\DemoCreatingCustomEvents\TextFile1.txt");
sw.Write(label1.Content.ToString());
sw.Close();
}
}
string json="";
private void button1_Click(object sender, RoutedEventArgs e)
{
ProductCategory deserializedProdCategory = new ProductCategory();
MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(json));
DataContractJsonSerializer ser = new DataContractJsonSerializer(deserializedProdCategory.GetType());
deserializedProdCategory = ser.ReadObject(ms) as ProductCategory;
ms.Close();
//you can fetch the data here and it is shown in label
label1.Content = deserializedProdCategory.ProdCategory[1].Product_ID + "//" + deserializedProdCategory.ProdCategory[1].Product_Name;
}
public class ProductCategory
{
public List<Product> ProdCategory = new List<Product>();
public ProductCategory()
{
ProdCategory = new List<Product>();
}
}
public class Product
{
public int Product_ID { get; set; }
public string Product_Code { get; set; }
public string Product_Name { get; set; }
public Uri Image_Small { get; set; }
}
Entity layer for your code
public class Country
{
public string id { get; set; }
public string first_name { get; set; }
public string last_name { get; set; }
public string username { get; set; }
public string password { get; set; }
public string email { get; set; }
public string photo { get; set; }
public string frame { get; set; }
}
public class MyData
{
public List<Country> countries { get; set; }
}
By using this you can modify it by seeing the above example
