I have a list view.when any one clicking the list it showing list content as
{first_name=abc, last_name=xyz, id=1, address=kolkata}
but I want those get those value individually from that string who to get that.
My onListItemClick Listner
protected void onListItemClick(ListView l, View v, int position, long id)
{
super.onListItemClick(l, v, position, id);
Object o = this.getListAdapter().getItem(position);
String return_data = o.toString();
Toast.makeText(this, ""+return_data, Toast.LENGTH_LONG).show();
}
Added total class including List adapter
public class showUserInfoListActivity extends ListActivity {
ArrayList<HashMap<String, String>> menuItems = new ArrayList<HashMap<String, String>>();
static final String KEY_ID = "id";
static final String KEY_FIRST_NAME = "first_name";
static final String KEY_LAST_NAME = "last_name";
static final String KEY_ADDRESS = "address";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.add_user_info_list);
//---get all Records---
DataBaseAdapter db = new DataBaseAdapter(this);
db.open();
Cursor c = db.getAllRecords();
if (c.moveToFirst())
{
do
{
HashMap<String, String> map = new HashMap<String, String>();
// adding each child node to HashMap key => value
map.put(KEY_ID, c.getString(0));
map.put(KEY_FIRST_NAME, c.getString(1));
map.put(KEY_LAST_NAME, " "+c.getString(2));
map.put(KEY_ADDRESS, c.getString(3));
// adding HashList to ArrayList
menuItems.add(map);
} while (c.moveToNext());
}
db.close();
// Adding menuItems to ListView
// All filed data are not shown in the list KEY_ID is hidden
ListAdapter adapter = new SimpleAdapter(this, menuItems,R.layout.user_info_list_item,
new String[] { KEY_FIRST_NAME, KEY_LAST_NAME, KEY_ADDRESS, KEY_ID },
new int[] {R.id.first_name , R.id.last_name, R.id.address});
setListAdapter(adapter);
}
//On select from the list show data
protected void onListItemClick(ListView l, View v, int position, long id)
{
super.onListItemClick(l, v, position, id);
Object o = this.getListAdapter().getItem(position);
//String return_data = o.toString();
MyClass return_data = (MyClass)o;
Toast.makeText(this, ""+return_data, Toast.LENGTH_LONG).show();
}
class MyClass{
}
}
Instead of
String return_data = o.toString();
you need to cast o to whatever class of object it is.
MyClass return_data = (MyClass)o;
Then you can access its fields and call its methods as usual.
In your case:
HashMap<String, String> returndata = (HashMap<String, String>) o;

When i run the following program:
ArrayList<HashMap<String, String>> AL = new ArrayList<HashMap<String, String>>();
#Override

super.onCreate(savedInstanceState);

ListView lv = (ListView) findViewById(R.id.lvoutinfo);

DBOpen open = new DBOpen(Outaccountinfo.this);
SQLiteDatabase db = open.getWritableDatabase();
Cursor cursor = db.query("outaccount", null, null, null, null, null, null, null);
while (cursor.moveToNext()) {
if (cursor.moveToFirst()) {
do {

String str_money = cursor.getString(cursor.getColumnIndex("outmoney"));

ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1,
str);
lv.setAdapter(arrayAdapter);
}
lv.setOnItemClickListener(new OnItemClickListener() {
#Override

// TODO Auto-generated method stub
HashMap<String, String> map = (HashMap<String, String>) parent.getItemAtPosition(position);
Toast.makeText(Outaccountinfo.this, map.get("type"), Toast.LENGTH_SHORT).show();
}
});
}
I receive the following error:
java.lang.String cannot be cast to java.util.HashMap
Who can help me to achieve the purpose without changing the purpose of the program?
Thanks!
You are using ArrayAdapter<String> Means that you pass your adapter object of Strings.
Now, when you clicked on your item and asked for parent.getItemAtPosition(position); you get an Object.
If you will go inside this function you can see that the Object that you get is by position and by the type you sent to the Adapter (String).
So, when you try to cast that String to (HashMap<String, String>) you get the exception.
Try to do something like that after you clicked:
HashMap<String, String> map = new HashMap<String, String>(); // Parameter in outside the click listener
lv.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
map.put("someKey", parent.getItemAtPosition(position));
Toast.makeText(Outaccountinfo.this, map.get("type"), Toast.LENGTH_SHORT).show();
}
});

}
}
return filter;
}
}
ArrayList<String> songsList;
so songsList is an ArrayList of Strings... if you do songsList.get(i) you'll have a String. The String object has not a "get" method, sou you cannot go further with
songsList.get(i).get("title").toString().
The same thing happens here:
searchResults=new ArrayList<HashMap<String, String>>
so if you call searchResults.add you have to pass a hashmap, not a String.
Please check your type definitions again and it will work.
songsList is a list of strings so you cannot do a get() on its item
I have a list view, each item is composed of three elements: picture view and 3 text view, the latter contains the name of a product, product price and quantity, i want when I click on the item it correspanding quantity increases by one.
Here's the code:

mSchedule.setViewBinder(new MyViewBinder());
maListViewPerso.setAdapter(mSchedule);
i tried this but only the first textview is changed :
maListViewPerso.setOnItemClickListener(new OnItemClickListener()
{ int compteur=0;
public void onItemClick(AdapterView<?> arg0, View arg1,
int position, long arg3) {
TextView t = (TextView)findViewById(R.id.quantite);
t.setText(String.valueOf(compteur));
compteur++;
}
});
Add an onListItemClick..
#Override
public void onListItemClick(ListView l, View v, int position, long id) {
// Your code here to increment the qty
}
EDIT
Use the View parameter passed in to access the proper view (i'm taking values from the code you added above, so it doesn't exactly match what I show above).
TextView t = (TextView) arg1.findViewById(R.id.quantite);
t.setText(String.valueOf(compteur));
I have done Muticolum listview onListItemClick .Its working fine.Problem is
This line String selection = l.getItemAtPosition(position).toString(); return this
{routeName=TestRoute2, outlets=5, routeCode=VRT002} .I want to get it selected row's 3rd column value.How to get it.
Please help me..
Thanks in advance..
What kind of Adapter? E.g. for a SimpleCursorAdapter you would do the following:
Cursor cursor = (Cursor) listView.getItemAtPosition(position);
long aLongValue = cursor.getLong(cursor.getColumnIndexOrThrow("anintegercolumn"));
ArrayList<HashMap<String, String>> historyArrayList;
SimpleAdapter histroyListAdapter;
HashMap<String, String> historyObjectMap;
for (CheckInCheckOutHistory checkOutHistoryObj : checkInCheckOutHistoryList) {
historyObjectMap = new HashMap<String, String>();
historyObjectMap.put("assetTag", checkOutHistoryObj.getAssetTag());
historyObjectMap.put("action", checkOutHistoryObj.getAction());
historyObjectMap.put("actionTime", checkOutHistoryObj.getActionDate());
if (checkOutHistoryObj.getAction().equals("Checked out")) {
historyObjectMap.put("gif", R.drawable.radio_button_yellow+ "");
} else {
historyObjectMap.put("gif", R.drawable.radio_button_green+ "");
}
historyArrayList.add(historyObjectMap);
}
histroyListAdapter = new SimpleAdapter(
ViewCheckInCheckOutHistory.this, historyArrayList,
R.layout.multi_colummn_list_text_style_small, new String[] {
"assetTag", "gif" , "action", "actionTime"},
new int[] { R.id.list_content_column1,
R.id.list_content_imagecolumn,
R.id.list_content_column3,
R.id.list_content_column4});
historyListView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
HashMap<String, String> historyObjectMapLocal = historyArrayList
.get(position);
final String assetTag = historyObjectMapLocal
.get("assetTag");
System.out.println("assetTag : " + assetTag);
}
});
In the above code the listView contents are populated using an ArrayList historyArrayList
and so the items at any column could be accessed using key ("assetTag", "gif" , "action", "actionTime").
