Android - Get value from HashMap and store to private String[] drinkImages

I am new to Android. I am using Fedor's Lazy Loading List. Is it possible to get all the values from a HashMap (values were retrieved from mysql) and store it to private String[] drinkImages?
String[] drinkImages' values will be passed to adapter Lazy_Adapter.
Or is there any other way to pass the value to Lazy_Adapter?
Code:
Lazy_ListItem.java
public class Lazy_ListItem extends Activity {
ListView list;
Lazy_Adapter adapter;
// Progress Dialog
private ProgressDialog pDialog;
// Creating JSON Parser object
JSONParser jParser = new JSONParser();
ArrayList<HashMap<String, String>> drinksList;

I hope you can help me. Thank you.

You can access perticular string on loacation with this code. Here i is an index number which may be 0,1,2 etc.
String yourstring = drinksList.get(i).get(TAG_DRK_IMAGE)

String[] drinkImages = (String[]) drinkList.get(0).values().toArray();

Yes, something like this will work .
public static void main(String[] args) {
Map<String, String> hm = new HashMap<String, String>(); // and yes. I am still using java 6 :(
hm.put("a", "a.jpg");
hm.put("b", "b.jpg");
String[] arr = new String[hm.size()];
hm.values().toArray(arr);
for (String s : arr) {
System.out.println(s);
}
}
O/P:
b.jpg
a.jpg

Try to iterate HashMap and build Array from HashMap value :
public String[] getStringArrayFromMap(HashMap<String,String> map){
String[] array = new String[map.size()];
int i=0;
for (String key : map.keySet()) {
array[i++] = map.get(key);
}
return array;
}

Android Lazy Loading List - retrieve images dynamically (MySQL & JSON)

I am new to Android.
I want to get the values of drk_image or TAG_DRK_IMAGE from the HashMap and store it to private String[ ] drinkImages. Is this possible?
Code:
Lazy_ListItem.java
public class Lazy_ListItem extends Activity {
ListView list;
Lazy_Adapter adapter;
// Creating JSON Parser object
JSONParser jParser = new JSONParser();
ArrayList<HashMap<String, String>> drinksList;
// url to get all drinks list
private static String url_all_drinks = "http://10.0.2.2/restosnapp/get_all_products.php";
// JSON Node names
private static final String TAG_SUCCESS = "success";
private static final String TAG_DRINKS = "drinks";
private static final String TAG_DRK_IMAGE = "drk_image";
// drinks JSONArray
JSONArray drinks = null;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.list_item);
list = (ListView) findViewById(R.id.list);
adapter = new Lazy_Adapter(this, drinkImages);
list.setAdapter(adapter);
}
#Override
public void onDestroy() {
list.setAdapter(null);
super.onDestroy();
}
/**
* Background Async Task to Load all drinks by making HTTP Request

class LoadAllProducts extends AsyncTask<String, String, String> {
/**

protected String doInBackground(String... args) {

List<NameValuePair> params = new ArrayList<NameValuePair>();
// getting JSON string from URL
JSONObject json = jParser.makeHttpRequest(url_all_drinks, "GET",
params);
// Check your log cat for JSON response
Log.d("All Drinks: ", json.toString());
try {
// Checking for SUCCESS TAG
int success = json.getInt(TAG_SUCCESS);
if (success == 1) {
// drinks found
// Getting Array of Drinks
drinks = json.getJSONArray(TAG_DRINKS);
// looping through All Drinks
for (int i = 0; i < drinks.length(); i++) {
JSONObject c = drinks.getJSONObject(i);
// Storing each json item in variable
String drk_image = c.getString(TAG_DRK_IMAGE);
// creating new HashMap
HashMap<String, String> map = new HashMap<String, String>();
// adding each child node to HashMap key => value
map.put(TAG_DRK_IMAGE, drk_image);
// adding HashList to ArrayList
drinksList.add(map);
}
}
} catch (JSONException e) {
e.printStackTrace();
}
return null;
}
}
private String[] drinkImages = {
"http://webitprojects.com/restaurant/images/drinks/drk_coffee.jpg",
"http://webitprojects.com/restaurant/images/drinks/drk_calamansijuice.jpg",
"http://webitprojects.com/restaurant/images/drinks/drk_blackgulaman.jpg",
"http://webitprojects.com/restaurant/images/drinks/drk_avocadoshake.jpg",
"http://webitprojects.com/restaurant/images/drinks/drk_durianshake.jpg" }; }
The value of String[ ] drinkImages must be replaced with values from the HashMap (from the database) and so I can pass it to Lazy_Adapter.
I want to get the values from the database instead of just declaring it like this:
private String[] drinkImages = {
"http://webitprojects.com/restaurant/images/drinks/drk_coffee.jpg",
"http://webitprojects.com/restaurant/images/drinks/drk_calamansijuice.jpg",
"http://webitprojects.com/restaurant/images/drinks/drk_blackgulaman.jpg",

EDIT:
Output:
This is the output if I have declared private String[] drinkImages. I am hoping to get the same output when getting it from the database.

I am doing this for my thesis. Really appreciate any help.
Thanks a lot~

Because you are using AsyncTask, maybe your task isn't finished yet.
So, you should add your adapter instance and assign it to your listview in onPostExecute method.
Please change your LazyListItem.java looklike below code:
import java.util.ArrayList;
import java.util.HashMap;
import org.json.JSONArray;
import android.os.AsyncTask;
import android.widget.ListView;
public class Lazy_ListItem extends Activity {
ListView list;
Lazy_Adapter adapter;
// Creating JSON Parser object
JSONParser jParser = new JSONParser();
ArrayList<HashMap<String, String>> drinksList;
// url to get all drinks list
private static String url_all_drinks = "http://10.0.2.2/restosnapp/get_all_products.php";
// JSON Node names
private static final String TAG_SUCCESS = "success";
private static final String TAG_DRINKS = "drinks";
private static final String TAG_DRK_IMAGE = "drk_image";
// Your Images Array
private String[] drinkImages;
// drinks JSONArray
JSONArray drinks = null;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.list_item);
list = (ListView) findViewById(R.id.list);
new LoadAllProducts().execute();
}
#Override
public void onDestroy() {
list.setAdapter(null);
super.onDestroy();
}

try {

int success = json.getInt(TAG_SUCCESS);
if (success == 1) {
// drinks found
// Getting Array of Drinks
drinks = json.getJSONArray(TAG_DRINKS);
// Define Lenght for Images Array
drinkImages = new String[drinks.length()];
// looping through All Drinks
for (int i = 0; i < drinks.length(); i++) {
JSONObject c = drinks.getJSONObject(i);
// Storing each json item in variable
String drk_image = c.getString(TAG_DRK_IMAGE);
// Add image into Array
drinkImages[i] = drk_image;
// creating new HashMap
HashMap<String, String> map = new HashMap<String, String>();
// adding each child node to HashMap key => value
map.put(TAG_DRK_IMAGE, drk_image);
// adding HashList to ArrayList
drinksList.add(map);
}
}
} catch (JSONException e) {

Fragment list data not passing correctly to activity

When I am clicking on my list items only the 1st item's id is going to the next activity. As I am getting patient name and id in this list fragment and passing the patient id to another activity, only the 1st list item's id is passing through even if I tap on another item... Hope you got my point...
Here is my ListFragment,
public class AllPatient extends ListFragment {

// url to get all products list

// TODO Auto-generated method stub
onAttach(getActivity());
//lv.setAdapter(adapter);
String id1 = ((TextView) getView().findViewById(R.id.pid)).getText().toString();
System.out.println("all patient"+id1);
Bundle bundle = new Bundle();
bundle.putString("TAG_PATIENT_ID",id1 );
System.out.println("bundle"+id1);
Intent i = new Intent(getActivity(),DocPresc.class);
i.putExtras(bundle);
startActivity(i);
//passData(date);
Toast.makeText(

getListView().getItemAtPosition(position).toString(),
Toast.LENGTH_LONG).show();
}
class LoadAllPatients extends AsyncTask<String, String, String> {

// Check your log cat for JSON reponse
Log.d("All Patients: ", json.toString());
try {

int success = json.getInt(TAG_SUCCESS);
if (success == 1) {
// products found

// looping through All Products
for (int i = 0; i < products.length(); i++) {

// adding each child node to HashMap key => value
map.put(TAG_PATIENT_ID, id);
map.put(TAG_PATIENT_NAME, name);
// adding HashList to ArrayList
productsList.add(map);
}
} else {
}
} catch (JSONException e) {
e.printStackTrace();
}
return null;
}
/**

* **/
protected void onPostExecute(String file_url) {
// dismiss the dialog after getting all products
// pDialog.dismiss();
// updating UI from Background Thread
getActivity().runOnUiThread(new Runnable() {
public void run() {
ListAdapter adapter = new SimpleAdapter(
getActivity(), productsList,
R.layout.list_item1, new String[] { TAG_PATIENT_ID,
TAG_PATIENT_NAME},
new int[] { R.id.pid, R.id.name });
// updating listview
//setListAdapter(adapter);
setListAdapter(adapter);
}
});
}
}
}

Try this.
Change this line:
String id1 = ((TextView) getView().findViewById(R.id.pid)).getText().toString();
to
String id1 = ((TextView) v.findViewById(R.id.pid)).getText().toString();

Q2:why GetView is called infinitely at back-end though list is displayed successfully

i HAVE SOLVED MY PROBLEM THIS WAY
HashMap<String, Object> item = productsList.get(position);

How to parse Inner json objects arrays

I am working with the ESPN Sports API. Can any one help me how to parse this?
I am pasting my code, I am able to parse only the name and id–please help how to parse inner objects items.
public class BaseballActivity extends ListActivity{
private static String url = "http://api.espn.com/v1/sports/baseball?apikey=h29yphwtf7893hktfbn7cd5g";
private static final String TAG_SPORTS = "sports";
private static final String TAG_ID = "id";
private static final String TAG_TIMESTAMP = "timestamp";
private static final String TAG_NAME = "name";
private static final String TAG_NEWS = "news";
private static final String TAG_HEADLINES = "headlines";
private static final String TAG_LINKS = "links";
private static final String TAG_API = "api";
private static final String TAG_SPORTS1 = "sports";
private static final String TAG_HREF = "href";
JSONArray sports = null;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
// HashMap for ListView
ArrayList<HashMap<String, String>> sportsList = new ArrayList<HashMap<String, String>>();
// creating Json parser instance
JSONParser jParser = new JSONParser();
// getting Json String from url
JSONObject json = jParser.getJSONFromUrl(url);
try{
// Getting Array of Contacts
sports = json.getJSONArray(TAG_SPORTS);
// looping through All Contacts
for(int i = 0; i < sports.length(); i++){
JSONObject c = sports.getJSONObject(i);
//String news = c.getString(TAG_NEWS);
// String headlines = c.getString(TAG_HEADLINES);
String name = c.getString(TAG_NAME);
// String timestamp = c.getString(TAG_TIMESTAMP);
String id = c.getString(TAG_ID);
// JSONObject links = c.getJSONObject(TAG_LINKS);
// JSONObject api = c.getJSONObject(TAG_API);
// JSONObject sports = c.getJSONObject(TAG_SPORTS1);
// String href = c.getString(TAG_HREF);
HashMap<String, String> map = new HashMap<String, String>();
// map.put(TAG_TIMESTAMP, timestamp);
map.put(TAG_NAME, name);
// map.put(TAG_NEWS, news);
// map.put(TAG_HEADLINES, headlines);
map.put(TAG_ID, id);
// map.put(TAG_HREF, href);
sportsList.add(map);
}
}
catch (JSONException e) {
e.printStackTrace();
}
ListAdapter adapter = new SimpleAdapter(this, sportsList,
R.layout.list_item,
new String[]{TAG_NAME,TAG_ID} , new int[] {
R.id.id,R.id.name});
setListAdapter(adapter);
}
}
here is my link I am using
Sample Link

I would recomend you to use gson. For me it was much more easier to work with...
EDIT: (some sample code)
Download the gson-2.2.2.jar add it to your dependencies
Create a base class (when you use more than one request)
public abstract class RequestBase {
public String ToJson(){
Gson gson = new Gson();
return gson.toJson(this);
}
public abstract String getUrl();
protected String getBaseUrl(){
return //Your URL;
}
}
Make a class which will execute your request..
Make classes for the requests and responses. Then you can just enter them with getters and setters:
public class SomeRequest extends RequestBase {
#SerializedName("Parameter1")
private int Parameter1;
public void setParameter1(int Parameter1) {
this.Parameter1= Parameter1;
}
public int getParameter1() {
return Parameter1;
}
#Override
public String getUrl() {
return this.getBaseUrl() +"YOUR/OWN/URL" + Parameter1;
}
}
and
public class SomeResponse {
#SerializedName("responseParameter1")
private int responseParameter1;
#SerializedName("responseParameter2")
private String responseParameter2;
public void setResponseParameter1(int responseParameter1) {
this.responseParameter1= responseParameter1;
}
public int getResponseParameter1() {
return responseParameter1;
}
public void setResponseParameter2(String responseParameter2) {
this.responseParameter2= responseParameter2;
}
public String getResponseParameter1() {
return responseParameter2;
}
}
