Google Maps And ListView in one activity in android?

I am trying to fit a Google Maps View and a ListView into one activity. The MapsView shall take 2/3 of the upper side, and the list 1/3 of the lower side (in portrait).
in this way assume it as portrait:
Both, the MapsView and the ListView, will receive the same JSON information, they will get onCreate(). I was already able to fit the MapsView on 2/3 of the screen, but the ListView wont receive any data. Can someone tell me, how to adress a ListView correct, when the superclass isnt ListActivity?
here is my code:
// url to make request
private static String url = ""; //here pass the url
// JSON Node names
private static final String TAG_LOCATION = "location";
private static final String TAG_LOCATION1= "location";
private static final String TAG_LOCATION_ID = "LocationID";
private static final String TAG_NAME = "Name";
private static final String TAG_PHONE = "Phone";

You have to create the adapter BEFORE setting it as the adapter of the ListView. Also, you have two variables named LocationList, which is generally bad practice. Try:
public void onCreate(Bundle savedInstanceState) {
// Hashmap for ListView
ArrayList<HashMap<String, String>> listOfLocations = new ArrayList<HashMap<String, String>>();
... // existing code here
adapter = new SimpleAdapter(this, listOfLocations,
R.layout.list_item,
new String[] { TAG_NAME }, new int[] {
R.id.name});
locationList.setAdapter(adapter);
}

You declare your string array p_lat & p_lon as null that's why your application get Force Closed. Your JSON parsing code is perfectly working.
You have to initialize string array with specific size as below.
String[] p_lat= new String[10];
String[] p_lon= new String[10];
You can also your ArrayList for better performance.

JSONObject c = place.getJSONObject(i);
are you sure that every index (i) is a jsonobject and not a other value/string ?
System.out.println("Testingggg..." + json.length());
try Integer.toString(json.length())

i am using wampserver and it appear that i must change
private static String url = "http://localhost/test/json_parser.php";
to
private static String url = "http://10.0.2.2/test/json_parser.php";
the problem seems to be caused by the incorrect address
this is why when you have problem don't forget to use log.d("","");

as you have only to variable to pass so use intent and pass the data ......and i think you have rest of code writen
put in the JSONActivity from where you want to open mapActivity and you alos have the variable latitude and longitude with their values
Intent i= new Intent(getApplicationContext(), mapActivity.class);
i.putExtra("lattitude",lattitude);
i.putExtra("longitude",longitude);
startActivity(i);
Then in the new activity mapActivity, retrieve those values:
inplace of this put String coordinates[] = {"5.550381", "95.318699"};
Bundle extras = getIntent().getExtras();
if(extras !=null) {
String lattitude= extras.getString("lattitude");
String longitude= extras.getString("longitude");
double lat = Double.parseDouble(lattitude);
double lng = Double.parseDouble(longitude);
}

You get latitude & longitudes like 51.509998321533,-0.12999999523163
but in android geopoint accepts only int values.
now create a function which will take these values & restric them upto 6 decimal points & you will get result as you wanted
Function will be like
double roundTwoDecimals(double d){
DecimalFormat twoDForm = new DecimalFormat("#.######");
return Double.valueOf(twoDForm.format(d));
}
this way you will get double value & then multiply it with 10E6 & you will get int which you need to use in creating GeoPoints..

I am not suere if it makes a difference but the line
latitudeAry.add(c.getString(TAG_lONGITUDE).toString());
has a lowercase L in lONGITUDE

You need to create an ItemizedOverlay for that. Here is one sample project from my books that shows adding an ItemizedOverlay to a MapView.
