I am having a bit of trouble with android. I have a sorted listview of items retrieved from a database using xml parsing.
i have to display the product on list view with sorted by price
This is my xml feed:
<Feed>
<category>
<Product>
<Name>New Masters of Flash</Name>
<Price>79.99</Price>
</Product>
<Product>
<Name>Professional Java Server Programming</Name>
<Price>63.99</Price>
</Product>
<Product>
<Name>Designing Web Usability</Name>
<Price>80.00</Price>
</Product>
</category>
</Feed>
This is my android code:
public class Catalogue extends Activity {
// static String URL = "https://dl.dropbox.com/u/48258247/catalogue.json";
static final String URL = "http://192.168.1.168/xcart432pro/internet.xml";
static String KEY_CATEGORY = "Product";
static final String KEY_TITLE = "Name";
static final String KEY_DESCRIPTION = "Description";
static final String KEY_COST = "Price";
static final String KEY_THUMB_URL = "Image";
ListView list;
ListAdapter adapter;
/** Called when the activity is first created. */
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final ArrayList<HashMap<String, String>> songsList = new ArrayList<HashMap<String, String>>();
XMLParser parser = new XMLParser();
String xml = parser.getXmlFromUrl(URL); // getting XML from URL
Document doc = parser.getDomElement(xml); // getting DOM element
NodeList nl = doc.getElementsByTagName(KEY_CATEGORY);
// looping through all song nodes <song>
for (int i = 0; i < nl.getLength(); i++) {
// creating new HashMap
HashMap<String, String> map = new HashMap<String, String>();
Element e = (Element) nl.item(i);
// adding each child node to HashMap key => value
map.put(KEY_TITLE, parser.getValue(e, KEY_TITLE));
map.put(KEY_DESCRIPTION, parser.getValue(e, KEY_DESCRIPTION));
map.put(KEY_COST, parser.getValue(e, KEY_COST));
map.put(KEY_THUMB_URL, parser.getValue(e, KEY_THUMB_URL));
// adding HashList to ArrayList
songsList.add(map);
}
list=(ListView)findViewById(R.id.listView1);
// Getting adapter by passing xml data ArrayList
adapter=new ListAdapter(this, songsList);
list.setAdapter(adapter);
// Bundle bundle = getIntent().getExtras();
// KEY_CATEGORY=bundle.getString(KEY_SUBCATE);
// Click event for single list row
list.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
HashMap<String, String> map = songsList.get(position);
Intent in = new Intent(
Catalogue.this,
com.ssmobileproductions.catalogue.SingleMenuItem.class);
in.putExtra(KEY_TITLE, map.get(KEY_TITLE));
in.putExtra(KEY_DESCRIPTION, map.get(KEY_DESCRIPTION));
in.putExtra(KEY_THUMB_URL, map.get(KEY_THUMB_URL));
in.putExtra(KEY_COST, map.get(KEY_COST));
startActivity(in);
}
});
Here i have to display the product on list view with sorted by price.How can i do.please help me programmatically in android.
Edit:
I have added some code like below:
Button btninsert = (Button) findViewById(R.id.sort);
btninsert.setOnClickListener(new View.OnClickListener() {
final ArrayList<HashMap<String, String>> songsList = new ArrayList<HashMap<String, String>>();
public void onClick(View v) {
Collections.sort(songsList, new PriceComparator());
}
});
final ArrayList<HashMap<String, String>> songsList = new ArrayList<HashMap<String, String>>();
XMLParser parser = new XMLParser();
String xml = parser.getXmlFromUrl(URL); // getting XML from URL
Document doc = parser.getDomElement(xml); // getting DOM element
NodeList nl = doc.getElementsByTagName(KEY_CATEGORY);
create one class and wrote the code below:
public class PriceComparator implements Comparator<HashMap<String, String>> {
static final String KEY_COST = "Price";
public PriceComparator() {
// TODO Auto-generated constructor stub
}
public int compare(HashMap<String, String> map1, HashMap<String, String> map2) {
return map1.get(KEY_COST).compareTo(map2.get(KEY_COST));
}
Now i have to run the app and click the button means nothing is happened????
But i have to display product list is sorted by price.
I believe you need to use a custom Comparator:
Comparator<HashMap<String, String>> comparator = new Comparator<HashMap<String, String>>() {
#Override
public int compare(HashMap<String, String> map1, HashMap<String, String> map2) {
return map1.get(KEY_COST).compareTo(map2.get(KEY_COST));
}
};
And then sort your list before creating your adapter with:
Collections.sort(songsList, comparator);
Addition
You need to do make a few small changes.
Make songsList a field variable, like list and adapter:
ListView list;
ListAdapter adapter;
ArrayList<HashMap<String, String>> songsList; // Add me!
Update how you initialize songsList:
songsList = new ArrayList<HashMap<String, String>>(); // Shorten me!
Change your onClick method:
public void onClick(View v) {
Collections.sort(songsList, comparator);
adapter.notifyDataSetChanged(); // Add me!
}
display the product on list view with sorted by price
=> As you are having ArrayList>, you need to create custom Comparator to make comparison.
For example:
public class PriceComparator implements Comparator<HashMap<String, String>> {
public PriceComparator() {
// TODO Auto-generated constructor stub
}
public int compare(HashMap<String, String> map1, HashMap<String, String> map2) {
return map1.get(KEY_COST).compareTo(map2.get(KEY_COST));
}
}
And to apply this custom comparator to your ArrayList>, do like:
Collections.sort(mylist, new PriceComparator());
Use Hashtable and sort the keys like following:
Here hashTable will contain name and price, and keys will contain the price, so sorting keys and then addind the sorted elements in sortedItems Vector will return you the sorted elements.
Hashtable hash = new Hashtable();
Vector<String> sortedItems = new Vector<String>();
Enumeration enumeration = hash .keys();
Vector keySet = new Vector();
while (enumeration.hasMoreElements()) {
keySet.add(enumeration.nextElement());
}
Collections.sort(keySet);
Iterator i = keySet.iterator();
String str;
while (i.hasNext()) {
str = (String) i.next();
sortedItems.addElement(hash .get(str));
Log.e("", (str + ":" + hash .get(str)));
}

I'm trying to display a listview with data out of openERP / odoo.
OpenERP returns an list of objects that I'm trying to use into a listview, but it prints out "Ljava.lang.object#number".
listOfValues return the list of objects, in my onPostExecute I want to connect it with the listview. But it doesn't work, anyone suggestion?
private class ListViewLoaderTask extends AsyncTask{
#Override
protected SimpleAdapter doInBackground(String... strJson) {
connector=new OpenerpRpc(getBaseContext());
connector.Config();
current_page += 1;
listOffValues = getListOffFieldValues(current_page, false, listOffValues);
String[] from = { "project_id"};
int[] to = { R.id.tv_address};
SimpleAdapter adapter = new SimpleAdapter(getBaseContext(), listOffValues, R.layout.lv_gps_layout, from, to);
return adapter;
}
/** Invoked by the Android on "doInBackground" is executed */
#Override
protected void onPostExecute(final SimpleAdapter adapter) {
// Setting adapter for the listview
mListView.setAdapter(adapter);
for(int i=0;i<adapter.getCount();i++){
HashMap<String, Object[]> hm = (HashMap<String, Object[]>) adapter.getItem(i);
final HashMap<String, String> companyDetails = new HashMap<String, String>();
Object po_ids = (Object[]) hm.get("project_id");
Object[] ret=(Object[]) hm.get("project_id");
Integer number = ((Integer) hm.get("project_id")[0]);
String projectId = ((String) hm.get("project_id")[1]);
companyDetails.put("project_id",projectId);
adapter.notifyDataSetChanged();
mListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,int position, long id) {
String listName;
HashMap<String, String> hmDownload = new HashMap<String, String>();
String l = companyDetails.get("project_id");
Intent myIntent = new Intent(MainActivity.this, YardActivity.class);
myIntent.putExtra("id", Long.toString(id));
myIntent.putExtra("position", Integer.toString(position)); //Optional parameters
MainActivity.this.startActivity(myIntent);
}
});
}
progress.dismiss();
Log.d("/****","Data from odoo is finished");
}
}
Here is the output when i debug:
http://i62.tinypic.com/24esx87.png
I updated my example where you can see that I can get the name of the project out of the list. But when I try to visulize that It print that java.lang string. Is your solution the only solution? When I hit on an item in my listview I get the projectId that I hit, so why it dont what to visiulize the string value?
HashMap<String, Object[]> hm = (HashMap<String, Object[]>)adapter.getItem(i);
change to
HashMap<String, MyModel[]> hm = (HashMap<String, MyModel[]>) adapter.getItem(i);
where my model is a class you create that describe your data,
take a look at ObjectItem.java

When I click on Components in ListView put Mac as id Components = parent_id Mac
In my previous app, I had a listview and and edittext at the bottom of it. I have been using the textwatcher in the edittext to filter a listview. The contents of the listview come from a simplecursoradapter.
edittext.addTextChangedListener(filterTextWatcher);
cursor.setFilterQueryProvider(new FilterQueryProvider() {
#Override
public Cursor runQuery(CharSequence constraint) {
Cursor cursor=mDbHelper.fetchFilteredNotes(edittext.getText().toString());
return cur;
}
});
private TextWatcher filterTextWatcher = new TextWatcher() {
public void afterTextChanged(android.text.Editable s) {
};
public void beforeTextChanged(CharSequence s, int start, int count, int after) {};
public void onTextChanged(CharSequence s, int start, int before, int count) {
simplecursoradapter.getFilter().filter(s.toString());
};
};
In my current app, I have an expandablelistview. I would like to use a similar feature like filtering the content of the expandablelistview.
Am not sure if I can make use of textwatcher for this. Is there any other way to get this done or can I use textwatcher in this as well. ?
This is the relevant portion of code:
private DbAdapter mDbHelper;
List<Map<String, String>> groupData,groupDataCat;
List<List<Map<String, String>>> childData,childDataCat;
Map<String, String> curGroupMap;
List<Map<String, String>> meaning=null;
Map<String, String> curChildMap;
private static final String WORD = "WORD";
private static final String MEANING = "MEANING";
SimpleExpandableListAdapter mAdapter;
ExpandableListView elvCat;
temp=mDbHelper.fetchAllNotes();
temp.moveToFirst();
getActivity().startManagingCursor(temp);
if(temp.moveToFirst()){
groupDataCat = new ArrayList<Map<String, String>>();
childDataCat = new ArrayList<List<Map<String, String>>>();
for (int i = 0; i < temp.getCount(); i++) {
Map<String, String> catGroupMap = new HashMap<String, String>();
groupDataCat.add(catGroupMap);
catGroupMap.put(WORD, temp.getString(temp.getColumnIndexOrThrow(DbAdapter.KEY_WORD)));
List<Map<String, String>> meaning = new ArrayList<Map<String, String>>();
Map<String, String> catChildMap = new HashMap<String, String>();
meaning.add(catChildMap);
catChildMap.put(MEANING, temp.getString(temp.getColumnIndexOrThrow(DbAdapter.KEY_MEANING)));
childDataCat.add(meaning);
temp.moveToNext();
}
}
mAdapter = new SimpleExpandableListAdapter(
WordListFragment.this.getActivity(),
groupDataCat,
R.layout.word_list_item,
new String[] {WORD},
new int[] { R.id.tvWord },
childDataCat,
R.layout.meaning_list_item,
new String[] {MEANING},
new int[] { R.id.tvMeaning}
);
view=inflater.inflate(R.layout.word_list_temp, container, false);
elvCat = (ExpandableListView) view.findViewById(R.id.elvWord);
elvCat.setAdapter(mAdapter);
return view;
}
The way I got this to work was that in the onTextChanged() method, I called up a function which would query the database and get the filtered data. I repopulate the expandable listview again based on the query results.
private void populateList(String filter) {
temp = mDbHelper.fetchSugNotes(filter);
temp.moveToFirst();
this.startManagingCursor(temp);
groupDataCat = new ArrayList<Map<String, String>>();
childDataCat = new ArrayList<List<Map<String, String>>>();
for (int i = 0; i < temp.getCount(); i++) {
Map<String, String> catGroupMap = new HashMap<String, String>();
groupDataCat.add(catGroupMap);
catGroupMap.put(WORD, temp.getString(temp
.getColumnIndexOrThrow(DbAdapter.KEY_WORD)));
List<Map<String, String>> meaning = new ArrayList<Map<String, String>>();
Map<String, String> catChildMap = new HashMap<String, String>();
meaning.add(catChildMap);
catChildMap.put(MEANING, temp.getString(temp
.getColumnIndexOrThrow(DbAdapter.KEY_MEANING)));
childDataCat.add(meaning);
temp.moveToNext();
}
mAdapter = new SimpleExpandableListAdapter(this, groupDataCat,
R.layout.word_list_item, new String[] { WORD },
new int[] { R.id.tvWord }, childDataCat,
R.layout.meaning_list_item, new String[] { MEANING },
new int[] { R.id.tvMeaning });
elvCat.setAdapter(mAdapter);
I have an ArrayList<HashMap<Contact, Name>> and I want to populate a ListView with it. Here's my attempt (which is not working)
ArrayList<HashMap<String, String>> lista = new ArrayList<HashMap<String, String>>();
// Array of strings "titulos"
String titulos[] = { "Dolar (Transferencia)", "Euro (Transferencia)",
"Dolar (Efectivo)", "Euro (Efectivo)", "Dolar (cúcuta)",
"Euro (cucuta)" };
try {
JSONObject json = result; // result is a JSONObject and the source is located here: https://dl.dropbox.com/u/8102604/dolar.json
JSONObject root = json.getJSONObject("root");
JSONArray items = root.getJSONArray("item");
int j = 0;
for (int i = 0; i < items.length(); i++) {
JSONObject item = items.getJSONObject(i);
String key = item.getString("key");
String mount = item.getString("mount");
if (key.equals("TS") || key.equals("TE") || key.equals("EE")
|| key.equals("CE") || key.equals("ES")
|| key.equals("CS")) { // i did this since i only need the items where the key is equal to TS, TE, EE, CE, ES or CS.
HashMap<String, String> map = new HashMap<String, String>();
map.put("id", String.valueOf(i));
map.put(key, mount);
lista.add(map);
System.out.println(titulos[j] + "(" + key + "). BsF = " + mount); // just for debugging purposes
j++; // add 1 to j if key is equal to TS, TE, EE, CE, ES or CS. In this way i can associate the two arrays (item and titulos)
}
}
ListView lv = (ListView) myMainActivity.findViewById(R.id.listView1); // create a list view
lv.setAdapter(new ArrayAdapter<String>(contexto, android.R.layout.simple_list_item_1, lista)); // set adapter to the listview (not working)
} catch (JSONException e) {
Log.e("log_tag", "Error parsing data " + e.toString());
}
}
That last line is throwing an error in eclipse:
The constructor ArrayAdapter<String>(Context, int, ArrayList<HashMap<String,String>>) is undefined
I've tried everything but I still couldn't make it work, could you help me please?
Thanks in advance.
PS: Full source: https://gist.github.com/4451519
Just use a SimpleAdapter.
String[] from = new String[] { /* all your keys */};
int[] to = new int[] { /* an equal number of android.R.id.text1 */};
ListAdapter adapter = new SimpleAdapter(contexto, lista, android.R.layout.simple_list_item_1, from, to);
It would be simple (and more logical) if each item of your list contained a similarly formed object, not a different key every time.
I would replace
map.put(key, mount);
by
map.put("key", key);
map.put("value", mount);
and then the from and to are simply:
String[] from = new String[] { "value" };
int[] to = new int[] { android.R.id.text1 };
You'll have to create your own adapter if you really want to pass the whole list of HashMaps, as the ArrayAdapter<String> expects the third parameter in your case to be of the type List<String>.
You should follow #Tomislav Novoselec's suggestion in the comments, and create a List<String> from the HashMap values.
You need to use your own CustomArrayAdapter like below and consume this class in your code.
public class CustomArrayAdapter extends BaseAdapter {
private JSONArray jsonArray = null;
public ImageAdapter(Context c, JSONArray jsonArray) {
context = c;
this.jsonArray = jsonArray;
}
public int getCount() {
return jsonArray.length();
}
public View getView(int position, View convertView, ViewGroup parent) {
//DO YOUR CODE HERE
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
if (convertView == null) {
convertView = inflater.inflate(R.layout.list_item_view, null);
}else{
//Set values for your listview on the list item.
convertView.findViewById(R.id.someID).setText("GetJSONTEXT");
}
}
}
MY SUGGESTION FOR YOUR MAINACTIVITY
package com.kustomrtr.dolarparalelovenezuela;
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import com.loopj.android.http.*;
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
AsyncHttpClient client = new AsyncHttpClient();
client.get("http://192.168.1.5/dolar.json", new AsyncHttpResponseHandler() {
#Override
public void onSuccess(String response) {
System.out.println(response);
try {
JSONObject json = new JSONObject(response); // result is a JSONObject and the source is located here: https://dl.dropbox.com/u/8102604/dolar.json
JSONObject root = json.getJSONObject("root");
JSONArray items = root.getJSONArray("item");
ListView lv = (ListView) myMainActivity.findViewById(R.id.listView1); // create a list view
lv.setAdapter(new CustomArrayAdapter<String>(contexto, android.R.layout.simple_list_item_1, items));
} catch (JSONException e) {
Log.e("log_tag", "Error parsing data " + e.toString());
}
}
});
}
#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_main, menu);
return true;
}
}
You have to create you own Custom Adapter by Extending BaseAdapter in Android. Then you can set your custom adapter to the ListView by using the setAdapter method of the list view.
For your reference of please see the below small example of BaseAdapter. You need to pass your ArrayList< HashMaP > to the Adapter.

Hope this helps.
I have developed one android list view app using xml parsing.this is done for my first page.
After i have to click any product from list means am getting the detailed product description in displayed on next activity.it is also done.
Here i have to implement one part.
the detailed order page have one button add to cart.here i have to click this button means the selected product is added on my cart.how can i implement this.please help me.
This is my first activity(list view using xml parsing):
