Using pagination for listview in android

Using pagination for listview in android - java

I want to use pagination for a listview in android.I am loading 10 values at a time from a web service.But the problem is that the group of 10 values keep repeating.I have used an array list called ice_data for the adapter of the listview.The code:
public class VideoActivity extends Activity {
private ConnectionDetector cd;
public HttpResponse video_respons;
public String video_string_response1;
public ArrayList<NameValuePair> nameValuePairs_Video;
ArrayList<Ice_data> ice_list;
String URL="http://footballultimate.com/icebucket/index.php/api/getVideo";
String URL1="http://footballultimate.com/icebucket/index.php/api/getVideoByLimit";
JSONObject jsonobj;
JSONArray jsonarr;
Ice_data iceobj;
CustomIceAdapter ciadp;
ListView list;
int start = 1;
int limit = 10;
boolean loadingMore = false;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_video);
ice_list=new ArrayList<Ice_data>();
// GEt all Data for Video
cd = new ConnectionDetector(VideoActivity.this);
Config.isInternetPresent = cd.isConnectingToInternet();
if (!Config.isInternetPresent) {
AlertDialog.Builder builder = new AlertDialog.Builder(VideoActivity.this);
// Shuld be fail icon
builder.setIcon(R.drawable.ic_launcher);
builder.setMessage("Connection Not Available !" + "\n"
+ "Please enable your Internet Connection");
builder.setTitle("INTERNET CONNECTION");
builder.setPositiveButton("Ok",
new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
dialog.cancel();
}
});
AlertDialog alert = builder.create();
alert.show();
} else {
new GetVideos().execute();
}
// Get all Data for Video
list= (ListView) findViewById(R.id.videoList);
list.setOnScrollListener(new OnScrollListener() {
#Override
public void onScrollStateChanged(AbsListView arg0, int arg1) {
// TODO Auto-generated method stub
}
#Override
public void onScroll(AbsListView arg0, int firstVisibleItem, int visibleItemCount, int totalItemCount) {
int lastInScreen = firstVisibleItem + visibleItemCount;
if((lastInScreen == totalItemCount) && !(loadingMore)){
new GetVideos().execute();
}
}
});
}
class GetVideos extends AsyncTask<String, String, String> {
private ProgressDialog pDialog;
private HttpResponse vip_respons;
protected void onPreExecute() {
super.onPreExecute();
pDialog = new ProgressDialog(VideoActivity.this);
pDialog.setTitle("Processing...");
pDialog.setMessage("Please wait...");
pDialog.setCancelable(false);
pDialog.show();
}
#Override

httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
video_respons = httpclient.execute(httppost);
//video_string_response1 = getResponseBody(video_respons);
video_string_response1=responsetostring.getResponseBody(video_respons);
//Log.d("Store_Response", the_string_response1);
} catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
}
return null;
}
protected void onPostExecute(String video_string) {
try{
if(pDialog.isShowing()){
pDialog.dismiss();
}
}
catch(Exception e){
e.printStackTrace();
}
finally
{
pDialog.dismiss();
}
if (video_string_response1!=null) {
//displayjsonstring();
geticevalues(video_string_response1);
}
}
}
public void geticevalues(String result)
{
try {

//ice_list=new ArrayList<Ice_data>();
jsonarr=jsonobj.getJSONArray("video_data");
for(int i=0;i<jsonarr.length();i++)
{
JSONObject jso=jsonarr.getJSONObject(i);
iceobj=new Ice_data();
iceobj.title=jso.getString("title");
iceobj.image_URL=jso.getString("image");

ice_list.add(iceobj);
}
} catch (JSONException e) {

e.printStackTrace();
}
ciadp=new CustomIceAdapter(VideoActivity.this,ice_list);
loadingMore = false;
ciadp.notifyDataSetChanged();
list.setAdapter(ciadp);
start+=10;
}
How do i prevent the duplication of the values in the listview.?

FirebaseMessagingService is not getting called in AsyncTask's doInBackground

I have push Notification and I want to update realm objects when the phone gets a notification but when I try launch this:
RealmModelActiveUser actUser= realm.where(RealmModelActiveUser.class).equalTo("id",1).findFirst();
int myid= actUser.getUser().getUser_id();
new ServerBackgroundDownloadConversations(getApplicationContext()) {
#Override
protected void onPostExecute(String result) {
super.onPostExecute(result);
if (!result.equals("Error")) {
Log.i("Conversation", "UPDATED");
}
}
}.execute(myid);
The program jumps into the constructor ServerBackgroundDownloadConversations(getApplicationContext()) but doesn't call doInBackground and I don't know why.
My AsyncTask:
public class ServerBackgroundCreateConversation extends AsyncTask<RealmModelConversations,Void,String> {
Context context;
Handler handler;
String out= "";
#SuppressLint("HandlerLeak")
public ServerBackgroundCreateConversation(Context context) {
this.context = context;
handler = new Handler() {
#Override
public void handleMessage(Message msg) {
Bundle bundle= msg.getData();
if (bundle!=null){
out = (String) bundle.get("response");
} else {
out= "Error";
}
}
};
}
#Override
protected String doInBackground(RealmModelConversations... params) {
RealmModelConversations newConv = params[0];
UploadImageApacheHttp uploadTask = new UploadImageApacheHttp();
uploadTask.doFileUpload(newConv.getWork(newConv.getIntWork()), newConv, handler);
while (out.equals("")){
try {
Thread.sleep(50);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
return out;
}
#Override
protected void onPreExecute() {
}
#Override
protected void onPostExecute(String result) {
if (!result.equals("]") || !result.equals("")){
/// prihlási nového user aj do active (login/register)
CreateNewConversation(result);
} else {
result="Error";
}
}
#Override
protected void onProgressUpdate(Void... values) {
super.onProgressUpdate(values);
}
private void CreateNewConversation(String result){
Realm realm= Realm.getDefaultInstance();
try {
Gson gson = new Gson();
Type typeConv = new TypeToken<JsonSablonaConversations>() {
}.getType();
JSONObject pom;
JSONArray parentArray = new JSONArray(result);
JSONObject finalObject = parentArray.getJSONObject(0);
JsonSablonaConversations conversation = gson.fromJson(finalObject.toString(), typeConv);
final RealmModelConversations NewUserConv = new RealmModelConversations();
NewUserConv.setId_dialog(conversation.getId_dialog());
NewUserConv.setDate(conversation.getDate());
NewUserConv.setKey(conversation.getKey());
NewUserConv.setId_user(conversation.getId_user());
NewUserConv.setId_user2(conversation.getId_user2());
NewUserConv.setMeno(conversation.getMeno());
NewUserConv.setMeno2(conversation.getMeno2());
realm.executeTransaction(new Realm.Transaction() {
#Override

} catch (Exception e) {
int pom=4;
}

}
});
}

}
}
I try calling this ↑ from an external thread which is called from a Service, but my AsyncTask has handler and handler needs to be in runOnUIthread and in Thread. I can't get Activity because the thread is called from a Service which doesn't have access to Activity.

I solved my problem with this code
public String postData(int myUserId) {
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://www.gallopshop.eu/OFY/getConversations.php");
try {
// Add your data
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("id", Integer.toString(myUserId)));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpclient.execute(httppost);
String responseStr = EntityUtils.toString(response.getEntity());
return responseStr;
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
} catch (IOException e) {
// TODO Auto-generated catch block
}
return null;
}
I will try to put this method & after this method into simply thread, But maybe it's not needed because it's in a service.
Question - Do I put this into Thread or do you think it'll affect the performance of the app?

Shouldn't it be new MyTask().execute(myURL);?
Also because it's an AsyncTask you need to retain a reference to it until it's finished or else the garbage collector destroys it.

i write like this and solved thank you everyone:
if (JsonUtils.isNetworkAvailable(Search_Ringtone.this)) {
String str = Constant.SEARCH_RINGTONE_URL+Constant.SEARCH.replace(" ", "%20");
String myUrl = null;
try {
myUrl = URLEncoder.encode(str, "UTF-8");
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
new MyTask().execute(myUrl);

Android Search Listview duplicating items from JSON using EditText

I'm creating a simple search activity using EditText, ListView, JSON and Database, Every time i enter text in EditText, the listview must update(I'm using mysql, Select query LIKE), where the ListView that contains Items from Database using JSON, the items must be updated from the given condition using LIKE method, but it keeps in duplicating item in ListView every time i enter text.
inputSearch.addTextChangedListener(new TextWatcher() {
#Override
public void onTextChanged(CharSequence cs, int arg1, int arg2, int arg3) {
name = inputSearch.getText().toString();
searcher(name);
}
#Override
public void beforeTextChanged(CharSequence arg0, int arg1, int arg2,
int arg3) {
// TODO Auto-generated method stub
}
#Override
public void afterTextChanged(Editable arg0) {
// TODO Auto-generated method stub
}
});
String result;
private void searcher(String searched){
class searching extends AsyncTask<String, Void, String>{
#Override
protected String doInBackground(String... params) {
String paramSearched = params[0];
HttpClient httpClient = new DefaultHttpClient();
HttpGet httpGet = new HttpGet("http://....p.com/searchD.php?name=" + paramSearched);
try {
HttpResponse httpResponse = httpClient.execute(httpGet);
InputStream is = httpResponse.getEntity().getContent();
InputStreamReader inputStreamReader = new InputStreamReader(is);
BufferedReader bufferedReader = new BufferedReader(inputStreamReader);
StringBuilder stringBuilder = new StringBuilder();
String line = null;
while ((line = bufferedReader.readLine()) != null) {
stringBuilder.append(line + "\n");
}
result = stringBuilder.toString();
}catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
try{
JSONObject obj = new JSONObject(result);
nameslist = obj.getJSONArray("list");
for(int i = 0; i < nameslist.length(); i++){
JSONObject c = nameslist.getJSONObject(i);
String id = c.getString("ID");
String name = c.getString("Name");
HashMap<String, String> map = new HashMap<String, String>();
map.put("ID", id);
map.put("Name", name);
listofnames.add(map);
}
} catch (JSONException e) {
e.printStackTrace();
}
return null;
}
#Override
protected void onPreExecute() {
super.onPreExecute();
pDialog = new ProgressDialog(Search.this);
pDialog.setMessage("Searching Name. Please wait...");
pDialog.setIndeterminate(false);
pDialog.setCancelable(false);
pDialog.show();
}
#Override
protected void onPostExecute(String s) {
pDialog.dismiss();
runOnUiThread(new Runnable() {
public void run() {
ListAdapter adapter = new SimpleAdapter(
Search.this, listofnames,
R.layout.list_item1, new String[]{"ID",
"Name"},
new int[]{R.id.pid, R.id.name});
lv.setAdapter(adapter);
}
});
adapter.notifyDataSetChanged();
}
}
searching sh = new searching();
sh.execute(searched);
}

I think you should clear the "listofnames" list before you add new data into it to keep the list data newest and not duplicated.

Android : getParams() called two times dont know why?

Here getParams() method called two times and added two times data at my server. I have also noticed that my logs print twice in logcat. It occurs when I check two checkbox of from contact picker list view to send data to server.
Here is my json data :

To identify the root of this issue you'll need to debug and see what's the path in which getParams is called.
You could either breakpoint within getParams block or print the stack trace to log like so:
Throwable throwable = new IllegalArgumentException("Something");
throwable.printStackTrace();

Add this before adding request to request queue
request.setRetryPolicy(new DefaultRetryPolicy(
0,
DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));

How to integrate with jsonwebservices in Android?

I'm implementing json_web services in my Android application. I want to send the json data on jsonwebservices which is created in Java. When I run the application data does not send from the Android and does not show any error and also does not show any type of exception.
How can I identify whether my data is sent or not?
