I have to run json format which is shown in below
and have to parse this data into listview
and for this i tried following code
MainActivity
swipeRefreshLayout.setOnRefreshListener(this);
// swipeRefreshLayout.setRefreshing(true);
swipeRefreshLayout.post(new Runnable() {
#Override
public void run() {
swipeRefreshLayout.setRefreshing(true);

String postloadid = actorsList.get(position).gettitle();

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 am creating this app which shows the latest news, which gets data from

I went though your code and found some issues.
Some bad practices i found in your code are:
You are adding your urls in separate list with static specifier. Instead of this you should add the url variable in your News model directly. And you can directly retrieve the whole News model inside ListView > setOnItemClickListener.
You are creating Bitmap for all your images. It may cause OOM Exception. You should use any Image loading library instead.
I have fixed that all issues and created working code. Please do required changes which you want at your end.

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

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.
I'm doing a app can update data every 1 minutes, data will from database mysql on server to show on listview of my app android. My problem is when show data the first is ok but when show data the second on listview, data of the first and the second is duplication.Can you help me!
