Why does my ListView not update with SimpleAdapter?

Why does my ListView not update with SimpleAdapter? - android

I am retrieving JSON data from my server with which I want to update my ListView with. Everything works fine with retrieving the data but after it's finished and it tries to update the list I just get an empty page with no errors. Log.d("ListLocations", "after") is able to run as well so I don't see any problems with PostExecute and intiliasation of SimpleAdapter
I have adapted my code from this tutorial: http://www.androidhive.info/2012/05/how-to-connect-android-with-php-mysql/#ff0000
This is my ListActivity class:
public class ListLocations extends ListActivity
{
//Root url and controller
private static String root = "someURL/";
private static String locationsController = "locations";
// Progress Dialog
private ProgressDialog pDialog;
//JSON node names for locations
private static final String TAG_ID = "id";
private static final String TAG_NAME = "name";
private static final String TAG_TERRAIN = "terrain";
private static final String TAG_DIFFICULTY = "difficulty";
private static final String TAG_RATINGS = "ratings";
private static final String TAG_UID = "uid";
private static final String TAG_LONG= "long";
private static final String TAG_LAT= "lat";
private static final String TAG_DISTANCE= "distance";
private static final String TAG_COMID= "comid";
//Will be used to contain the list of locations extracted from JSON
ArrayList<HashMap<String, String>> list = new ArrayList<HashMap<String, String>>();
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_list_locations);
new GetLocations().execute(root + locationsController);
}
#Override
public boolean onCreateOptionsMenu(Menu menu)
{
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.activity_list_locations, menu);
return true;
}
class GetLocations extends AsyncTask<String, Void, Void>
{
// private ProgressDialog pDialog;
protected void onPreExecute()
{
super.onPreExecute();
pDialog = new ProgressDialog(ListLocations.this);
pDialog.setMessage("Loading locations. Please wait...");
pDialog.setIndeterminate(false);
pDialog.setCancelable(false);
pDialog.show();
}
#Override
public Void doInBackground(String... urls)
{
try
{
JSONHandler jsonHandler = new JSONHandler();
JSONObject json= jsonHandler.getJSONFromUrl(urls[0]);
Log.d("ListLocations",json.toString());
JSONArray locations = json.getJSONArray("locations");
int length = locations.length();
ArrayList<HashMap<String, String>> list = new ArrayList<HashMap<String, String>>();
for(int i = 0; i < length; i++)
{
JSONObject loc = locations.getJSONObject(i);
//Create HashMap
HashMap<String, String> map = new HashMap<String, String>();
//Get and store values into map
map.put("id", loc.getString(TAG_ID));
map.put("name", loc.getString(TAG_NAME));
map.put("distance", loc.getString(TAG_DISTANCE));
map.put("difficulty", loc.getString(TAG_DIFFICULTY));
map.put("terrain", loc.getString(TAG_TERRAIN));
map.put("ratings", loc.getString(TAG_RATINGS));
map.put("long", loc.getString(TAG_LONG));
map.put("lat", loc.getString(TAG_LAT));
map.put("uid", loc.getString(TAG_UID));
map.put("comid", loc.getString(TAG_COMID));
//Add map to list
list.add(map);
}
System.out.println(list);
}
catch (Exception e)
{
e.printStackTrace();
}
Log.d("ListLocations", "Successfully finished HTTP Request");
return(null);
}
/**
* After completing background task Dismiss the progress dialog
* **/
protected void onPostExecute(Void result) {
super.onPostExecute(result);
pDialog.dismiss();
// updating UI from Background Thread
runOnUiThread(new Runnable() {
public void run() {
Log.d("ListLocations", "inside run");
ListAdapter adapter = new SimpleAdapter(
ListLocations.this, list,
R.layout.list_item, new String[] { TAG_ID,
TAG_NAME},
new int[] { R.id.id, R.id.name });
Log.d("ListLocations", "after");
// updating listview
setListAdapter(adapter);
}
});
}
}
}
This is list_item.xml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<!-- location id (pid) - will be HIDDEN - used to pass to other activity -->
<TextView
android:id="#+id/id"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:visibility="gone" />
<!-- Name Label -->
<TextView
android:id="#+id/name"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:paddingTop="6dip"
android:paddingLeft="6dip"
android:textSize="17dip"
android:textStyle="bold" />
</LinearLayout>
This is activity_list_locations.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<ListView
android:id="#android:id/list"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
</LinearLayout>

You never put the data in the list field from the Activity that you use with the SimpleAdapter because the list variable in the doInBackground method is a local variable and not the field. Instead of:
//...
ArrayList<HashMap<String, String>> list = new ArrayList<HashMap<String, String>>();
for(int i = 0; i < length; i++) {
//...
write:
//...
list = new ArrayList<HashMap<String, String>>();
for(int i = 0; i < length; i++) {
//...
so you don't make a local variable and put the elements in the right list.

You have to use the Spinner like these below:
Spinner spin = (Spinner) findViewById(R.id.spinner);
spin.setOnItemSelectedListener(this);
ArrayAdapter aa = new ArrayAdapter(this,R.layout.spinner_item,ARRAYLIST_DATA_HERE);
aa.setDropDownViewResource(R.layout.spinner_item);
//Setting the ArrayAdapter data on the Spinner
spin.setAdapter(aa);
spin.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> arg0, View arg1,
int arg2, long arg3) {
String items=spinner.getSelectedItem().toString();
Log.i("Selected item : ",items);
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});
return true;
Use the spinner_item xml
xmlns:android="http://schemas.android.com/apk/res/android"
style="?android:attr/spinnerDropDownItemStyle"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#BAB7BA"
android:ellipsize="start"
android:gravity="left"
android:padding="10dip"
android:textColor="#color/white" />

Did you check On Click Listener for your ListView ?? I think that will solve your problem.. Use onClikcListener's on ItemClick event which will give you position and based on that position you can get item from your Arraylist which will give you id from that..

its showing error in the list_item, R.id.opcode , R.id.opname should i create a new XML file and write the code there or else will generate dynamically my present layout file is as show below can you guys help me out
<RelativeLayout>
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="#dimen/activity_vertical_margin"

tools:context=".MainActivity" >
<ListView
android:id="#android:id/list"
android:layout_width="fill_parent"
android:layout_height="wrap_content"/>
<RealativeLayout>
Not Able to Understand.

should i create a new XML file and write the code there or else will generate dynamicaly my present layout file
Look at the constructor
SimpleAdapter(Context context, List<? extends Map<String, ?>> data, int resource, String[] from, int[] to)
You need to have list_item.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<TextView
android:id="#+id/opcode"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_marginLeft="49dp"
android:layout_marginTop="51dp"
android:text="TextView" />
<TextView
android:id="#+id/opname"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottom="#+id/textView1"
android:layout_alignParentRight="true"
android:layout_marginRight="72dp"
android:text="TextView" />
</RelativeLayout>
Edit:
I think you do not have a ListActivity in the first place.
Secondly your json is
[ // is a json array noder
{ // json object node
"operatorCode": "AC",
"operatorName": "Aircel"
},
But you have
private static final String OPCODE="code"; // should be operatorCOde
private static final String OPNAME="name"; // operatorName
Keys are not matching the column names
Thirdly you do not have a json object at the top its a json array.
public class MainActivity extends ListActivity

Listview with headers and group items

I have created a listview with headers but I am unable to group items that fall under the same header.
Can someone advise me on what I should do?
Below are the codes to display the items into the listview:
