How to grouping data by date display in listview (data based on parse json)?

I wanna grouping my data such as an schedule by date or week where i display in listview.
I hope the result like this :
here my activity to show the data based on json parse :
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_tampil_semua_pgw);
listView = (ListView) findViewById(R.id.listView);
listView.setOnItemClickListener(this);
getJSON();
}
private void showEmployee(){
JSONObject jsonObject = null;
ArrayList<HashMap<String,String>> list = new ArrayList<HashMap<String, String>>();
try {
jsonObject = new JSONObject(JSON_STRING);
JSONArray result = jsonObject.getJSONArray(konfigurasi.TAG_JSON_ARRAY);
for(int i = 0; i<result.length(); i++){
JSONObject jo = result.getJSONObject(i);
String id = jo.getString(konfigurasi.TAG_ID);
String nama = jo.getString(konfigurasi.TAG_NAMA);
String pyg = jo.getString(konfigurasi.TAG_PENYELENGGARA);
String tmpt = jo.getString(konfigurasi.TAG_TEMPAT);
String tgl = jo.getString(konfigurasi.TAG_TGL);
String jam = jo.getString(konfigurasi.TAG_JAM);
String email = jo.getString(konfigurasi.TAG_EMAIL);
HashMap<String,String> employees = new HashMap<>();
employees.put(konfigurasi.TAG_ID,id);
employees.put(konfigurasi.TAG_NAMA,nama);
employees.put(konfigurasi.TAG_PENYELENGGARA,pyg);
employees.put(konfigurasi.TAG_TEMPAT,tmpt);
employees.put(konfigurasi.TAG_TGL,tgl);
employees.put(konfigurasi.TAG_JAM,jam);
employees.put(konfigurasi.TAG_EMAIL,email);
list.add(employees);
}
} catch (JSONException e) {
e.printStackTrace();

ListAdapter adapter = new MySimpleArrayAdapter(this, list);
listView.setAdapter(adapter);
}
And here my custom adapter :

How to show only list view items which value is equal to a value in the Json

iam creating an App which should show the Sights in a Listview.
The datas are parsed from a json.
At this json there is a column which declares in which City the sight is.
Now i would like to create a kind of a filter which should check the current Cityname with the City values in my Json.
For example there is a Sight in Berlin and my current city is Berlin, the Listview should show it. If the user is in Munich and the sight is in Berlin, the listview shouldnt show this item.
I get the current cityname value from a different Activity in a TextView.
Here is my Listview Activity:
public class Locations extends AppCompatActivity implements AdapterView.OnItemClickListener {
ArrayList<productforloc> arrayList;
ListView lv;
private String TAG = Locations.class.getSimpleName();
private TextView addressField; //Add a new TextView to your activity_main to display the address
private LocationManager locationManager;
private String provider;
int i = 1;
private ProgressDialog pDialog;
String name;
// URL to get contacts JSON
private static String url = "http://partypeople.bplaced.net/maptest.json";
ArrayList<HashMap<String, String>> contactList;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.content_main);
Intent i = getIntent();
String cityname = i.getExtras().getString("cityname");
TextView city = (TextView) findViewById(R.id.ort);
city.setText(cityname);
pDialog = new ProgressDialog(Locations.this);
pDialog.setMessage("Please wait...");
pDialog.setCancelable(true);
pDialog.show();
arrayList = new ArrayList<>();
lv = (ListView) findViewById(R.id.lv);
lv.setOnItemClickListener((AdapterView.OnItemClickListener) this);
runOnUiThread(new Runnable() {
#Override
public void run() {
new ReadJSON().execute(url);
}
});
final ImageButton filteropen = (ImageButton) findViewById(R.id.aufklaupen);
filteropen.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
RelativeLayout filter = (RelativeLayout) findViewById(R.id.filterloc);
filter.setVisibility(View.VISIBLE);
ImageButton filterclose = (ImageButton) findViewById(R.id.zuklappen);
filterclose.setVisibility(View.VISIBLE);
filteropen.setVisibility(View.INVISIBLE);
}
});
final ImageButton filterclose = (ImageButton) findViewById(R.id.zuklappen);
filterclose.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
RelativeLayout filter = (RelativeLayout) findViewById(R.id.filterloc);

}
}
private String readURL(String url){

po.getString("urlbtn"),
po.getString("Fsk"),

How to update listview after changing data in JSON?

Hello everyone and happy new year
I have JSON class where I retrieve some data that are retrieve from a database. The format of this JSON file is
{"people":[{"id":"15","first_name":"Theo","last_name":"Tziomakas","bio":"Hello from
Theo!!!","created":"2015-01-11 21:48:51"},
{"id":"16","first_name":"Jim","last_name":"Chytas","bio":"Hello from Chytas","created":"2015-01-11
21:53:42"}]}.
The idea is to retrieve the "first_name" and "second_name" in a listview. The "bio" should appear in another activity,but I don't know how to do that:(.
Here is my code.
public class MainActivity extends ActionBarActivity {
ListView list;
TextView fname;
TextView lname;
ArrayList<HashMap<String, String>> oslist = new ArrayList<HashMap<String, String>>();
//URL to get JSON Array
private static String url = "http://xxxxxxx/tutorials/index.php";
//JSON Node Names
private static final String TAG_OS = "people";
private static final String TAG_FIRST_NAME = "first_name";
private static final String TAG_SECOND_NAME = "last_name";
//private static final String TAG_BIO = "bio";
JSONArray android = null;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
oslist = new ArrayList<HashMap<String, String>>();
new JSONParse().execute();
}
private class JSONParse extends AsyncTask<String, String, JSONObject> {
private ProgressDialog pDialog;
#Override
protected void onPreExecute() {
super.onPreExecute();
fname = (TextView)findViewById(R.id.first_name);
lname = (TextView)findViewById(R.id.last_name);
//abio = (TextView)findViewById(R.id.bio);
pDialog = new ProgressDialog(MainActivity.this);
pDialog.setMessage("Getting Data ...");
pDialog.setIndeterminate(false);
pDialog.setCancelable(true);
pDialog.show();
}
#Override
protected JSONObject doInBackground(String... args) {
JSONParser jParser = new JSONParser();
// Getting JSON from URL
JSONObject json = jParser.getJSONFromUrl(url);
return json;
}
#Override
protected void onPostExecute(JSONObject json) {
pDialog.dismiss();
try {
// Getting JSON Array from URL
android = json.getJSONArray(TAG_OS);
for(int i = 0; i < android.length(); i++){
JSONObject c = android.getJSONObject(i);
// Storing JSON item in a Variable
String first_name = c.getString(TAG_FIRST_NAME);
String last_name = c.getString(TAG_SECOND_NAME);
//String bio = c.getString(TAG_BIO);
// Adding value HashMap key => value
HashMap<String, String> map = new HashMap<String, String>();
map.put(TAG_FIRST_NAME, first_name);
map.put(TAG_SECOND_NAME, last_name);
//map.put(TAG_BIO, bio);
oslist.add(map);
list=(ListView)findViewById(R.id.list);
ListAdapter adapter = new SimpleAdapter(MainActivity.this, oslist,
R.layout.list_v,
new String[] { TAG_FIRST_NAME,TAG_SECOND_NAME }, new int[] {
R.id.first_name,R.id.last_name});
list.setAdapter(adapter);
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
String bio = ((TextView) view.findViewById(R.id.bio))
.getText().toString();
switch (position) {
case 0:
Intent i = new Intent(MainActivity.this, SingleActivity.class);
i.putExtra("bio", bio);
startActivity(i);
break;
}
}
});
}
} catch (JSONException e) {
e.printStackTrace();
}
}
}
}
And finally I have the SecondActivity class,but nothing is shown when I click the first row of list.
public class SingleActivity extends ActionBarActivity {
TextView text;
JSONArray android = null;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_single);
text = (TextView)findViewById(R.id.text);
String bio = getIntent().getStringExtra("bio");
try {
JSONObject profileJSON = new JSONObject(bio);
android = profileJSON.getJSONArray(bio);
text.setText(""+android);
} catch (JSONException e) {
e.printStackTrace();
}
}
}
Thank you.
EDIT:The problem I had is fixed. Now I want to do something else. Let us suppose that we update the data in an existing row by changing "first_name,"last_name" and finally bio. It is done very easily in phpmyadmin tool. The problem is that the updated row is not shown in the listview. I have to reinstall the app in order to see it. Any ideas in that?

try this ,
replace onPostExecute with this
protected void onPostExecute(JSONObject json) {
pDialog.dismiss();
try {
list=(ListView)findViewById(R.id.list);
// Getting JSON Array from URL
android = json.getJSONArray(TAG_OS);
for(int i = 0; i < android.length(); i++){
JSONObject c = android.getJSONObject(i);
// Storing JSON item in a Variable
String first_name = c.getString(TAG_FIRST_NAME);
String last_name = c.getString(TAG_SECOND_NAME);
//String bio = c.getString(TAG_BIO);
// Adding value HashMap key => value
HashMap<String, String> map = new HashMap<String, String>();
map.put(TAG_FIRST_NAME, first_name);
map.put(TAG_SECOND_NAME, last_name);
map.put(TAG_BIO, bio);
oslist.add(map);
}
ListAdapter adapter = new SimpleAdapter(MainActivity.this, oslist,
R.layout.list_v,
new String[] { TAG_FIRST_NAME,TAG_SECOND_NAME }, new int[] {
R.id.first_name,R.id.last_name});
list.setAdapter(adapter);
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
String bio =oslist.get(position).get(TAG_BIO);
// switch (position) {
// case 0:
Intent i = new Intent(MainActivity.this, SingleActivity.class);
i.putExtra("bio", bio);
startActivity(i);
break;
//}
}
});
} catch (JSONException e) {
e.printStackTrace();
}
}
and SingleActivity
text = (TextView)findViewById(R.id.text);
String bio = getIntent().getStringExtra("bio");
text.setText(bio );

Pay attention to what you put in the intent.
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
String bio = ((TextView) view.findViewById(R.id.bio))
.getText().toString();
switch (position) {
case 0:
Intent i = new Intent(MainActivity.this, SingleActivity.class);
i.putExtra("bio", bio);
startActivity(i);
break;
}
}
notice that you take the text from a text view and add it to and intent.
When you retreive it use it as if its a json object.
If you want the bio string, you could put that in a variable, and then send it to an intent with just the string.
for example
ListAdapter adapter = new SimpleAdapter(MainActivity.this, oslist,
R.layout.list_v,
new String[] { TAG_FIRST_NAME,TAG_SECOND_NAME }, new int[] {
R.id.first_name,R.id.last_name});
list.setAdapter(adapter);
String bio = c.getString("bio");
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
switch (position) {
case 0:
Intent i = new Intent(MainActivity.this, SingleActivity.class);
i.putExtra("bio", bio);
startActivity(i);
break;
}
}
});
when retrieving it its easier to just do it with
public class SingleActivity extends ActionBarActivity {
TextView text;
JSONArray android = null;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_single);
text = (TextView)findViewById(R.id.text);
String bio = getIntent().getStringExtra("bio");
text.settext(bio)
}
}
now there is prob some bugs in these example, since i have not java or android sdk installed on my computer

How can i transfer dynamically generated data from one ListView in a screen to another?

My data comes dynamically in an array of textviews and I am entering some data in edit texts beside that.
All the data comes in the listview.
what I need to do is I need to transfer all the data in the text views as well as edittexts to another screen on a button click.

Android populate spinner with string array

Below I have attached my code for trying to add my string array, names, to the spinner as the options. As of now, I am not getting anything populating the array, and I am really not sure what I'm doing wrong. I have looked over other similar questions on this site, as well as using Google, and have come up empty. Can anyone give me some guidance? Thanks

Try this..
before calling addListenerOnSpinnerSelection(); method set adapter for that spinner.
adapter = new ArrayAdapter(RunesActivity.this,
android.R.layout.simple_spinner_dropdown_item,
runePageNames);
spinner.setAdapter(adapter );
addListenerOnSpinnerSelection();
