JSON Web service calling repeatedly

JSON Web service calling repeatedly - android

I am new to android. I write a code for JSON parsing. In this code i need to call JSON Web service repeatedly .How I can do that. Please help me
code:
public class MainActivity extends Activity implements OnItemClickListener {
private static final String rssFeed = "https://www.dropbox.com/s/rhk01nqlyj5gixl/jsonparsing.txt?dl=1";
private static final String ARRAY_NAME = "student";
private static final String ID = "id";
private static final String NAME = "name";
private static final String CITY = "city";
private static final String GENDER = "Gender";
private static final String AGE = "age";
private static final String BIRTH_DATE = "birthdate";
List<Item> arrayOfList;
ListView listView;
NewsRowAdapter objAdapter;
private static final String TAG = "Your Service";
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
listView = (ListView) findViewById(R.id.listview);
listView.setOnItemClickListener(this);
arrayOfList = new ArrayList<Item>();
if (Utils.isNetworkAvailable(MainActivity.this)) {
new MyTask().execute(rssFeed);
} else {
//showToast("No Network Connection!!!");
}
}
// My AsyncTask start...
class MyTask extends AsyncTask<String, Void, String> {
ProgressDialog pDialog;
#Override
protected void onPreExecute() {
super.onPreExecute();
pDialog = new ProgressDialog(MainActivity.this);
pDialog.setMessage("Loading...");
pDialog.setCancelable(false);
pDialog.show();
}
#Override
protected String doInBackground(String... params) {
return Utils.getJSONString(params[0]);
}
#Override
protected void onPostExecute(String result) {
super.onPostExecute(result);
if (null != pDialog && pDialog.isShowing()) {
pDialog.dismiss();
}
if (null == result || result.length() == 0) {
showToast("No data found from web!!!");
MainActivity.this.finish();
} else {
try {
JSONObject mainJson = new JSONObject(result);
JSONArray jsonArray = mainJson.getJSONArray(ARRAY_NAME);
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject objJson = jsonArray.getJSONObject(i);
Item objItem = new Item();
objItem.setId(objJson.getInt(ID));
objItem.setName(objJson.getString(NAME));
objItem.setCity(objJson.getString(CITY));
objItem.setGender(objJson.getString(GENDER));
objItem.setAge(objJson.getInt(AGE));
objItem.setBirthdate(objJson.getString(BIRTH_DATE));
arrayOfList.add(objItem);
}
} catch (JSONException e) {
e.printStackTrace();
}
Collections.sort(arrayOfList, new Comparator<Item>() {
#Override
public int compare(Item lhs, Item rhs) {
return (lhs.getAge() - rhs.getAge());
}
});
setAdapterToListview();
}
}
}
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
showDeleteDialog(position);
}
private void showDeleteDialog(final int position) {
AlertDialog alertDialog = new AlertDialog.Builder(MainActivity.this)
.create();
alertDialog.setTitle("Delete ??");
alertDialog.setMessage("Are you sure want to Delete it??");
alertDialog.setButton("No", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
});
alertDialog.setButton2("Yes", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
arrayOfList.remove(position);
objAdapter.notifyDataSetChanged();
}
});
alertDialog.show();
}
public void setAdapterToListview() {
objAdapter = new NewsRowAdapter(MainActivity.this, R.layout.row,
arrayOfList);
listView.setAdapter(objAdapter);
}
public void showToast(String msg) {
Toast.makeText(MainActivity.this, msg, Toast.LENGTH_LONG).show();
}
}

You can use alarm manager and call the webservice at a particular interval of time. You can chekc using alarm manager here

You can use the java class TimerTask for repeated execution of a method.
See also: Timer, which uses TimerTask to schedule tasks.

Thread exiting with uncaught exception on a specific function

Im developing an android app that performs add, update, and delete operations on data on a localhosted MySQL Database. Everything is working fine except for the update part. It happens on the activity ViewFeedingSched when im trying to update the data. The app crashes when the update button is pressed or simply when the function for updating is called. The logcat is giving a message: threadid=1: thread exiting with uncaught exception (group=0x41640c80) . I've seen several solutions and they're mostly about not initializing some objects or having null values. I can't seem to find where I have not initialized something. It was working before and I don't know what I've changed with the program. Below is the codes of the ViewFeedingSched class.
EDIT
I've added the codes for the class that goes before the ViewFeedingSched class which is the FeedingSchedList class. It's layout contains a ListView with the data being listed, and an onItemClick method that opens the ViewFeedingSched class whenever an item (data) is clicked.
public class ViewFeedingSched extends AppCompatActivity implements View.OnClickListener {
private EditText editTextSchedNo;
private EditText editTextFeedTime;
private EditText editTextFeedAmt;
private TextView textViewCurrentTimeSet;

#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.view_feeding_sched);
Intent intent = getIntent();
id = intent.getStringExtra(Config.SCHED_ID);
ftime = intent.getStringExtra(Config.FEEDTIME);
//famt = intent.getStringExtra(Config.FEEDAMT);
editTextSchedNo = (EditText) findViewById(R.id.ET_SchedNo);
editTextFeedTime = (EditText) findViewById(R.id.ET_FeedTime);

how to show only selected data when spinner value is selected in android?

I have got 3 spinner where data is coming from server, if we click the search button without selecting any spinner then on next activity , it should show all list(all product without condition), but if we select according to 3 spinner then it should show only related item.I am getting all item when clicking search button without selecting anything but i am not getting selected item in next activity .

In Pigeon listing activity there is 1 option like search activity where user can search without selecting any item just like in search activity.

Set listeners for each of your spinners
setOnItemSelectedListener
In onItemSelected method , get the selected value in a variable and pass on these values to next activity.
E.g.
yourSpinner.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> arg0, View arg1,
int arg2, long arg3) {
String yourValue = yourSpinner.getSelectedItem().toString();
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});
