Acess listview data from context menu

Acess listview data from context menu - android

I have created a list view with the following data: id name date and i created a context menu my problem is to retreive the name from the item selected in the context menu option. How can i do this:
#Override
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo){
getMenuInflater().inflate(R.menu.context, menu);
}
public boolean onContextItemSelected(MenuItem item) {
AdapterContextMenuInfo info = (AdapterContextMenuInfo) item.getMenuInfo();
switch(item.getItemId()) {
case R.id.item1:
return true;
case R.id.item2:
return true;
default:
return super.onContextItemSelected(item);
}
}
}
my code:
public class AllProductsActivity extends ListActivity {
// Progress Dialog
private ProgressDialog pDialog;
// Creating JSON Parser object
JSONParser jParser = new JSONParser();
ArrayList<HashMap<String, String>> productsList;
// url to get all products list

}
}
}

The info.position is the index in the collection of the element that was pressed to invoke the context menu. So YourObject temp = yourCollection.get(info.position); will give you the whole object.
EDIT:
public boolean onContextItemSelected(MenuItem item) {
AdapterContextMenuInfo info = (AdapterContextMenuInfo) item.getMenuInfo();
HashMap <String, String> product = productsList.get(info.position);
String name = product.get(TAG_NAME);
//name contians the name of the product, similarly you can get the others

So in my 1 activity i pass in the context menu item 1 the values that i want the id9 and id2, ive made a toast to see what values they are passing, and they pass the way i want 637 and 8
public boolean onContextItemSelected(MenuItem item) {
AdapterContextMenuInfo info = (AdapterContextMenuInfo) item.getMenuInfo();
switch(item.getItemId()) {
case R.id.item1:
HashMap <String, String> product2 = productsList.get(info.position);
String id9 = product2.get("id");
String id3 = product2.get(TAG_DATA);
String id4 = product2.get(TAG_ESTAB);
String id5 = product2.get(TAG_HORA);
String id6 = product2.get(TAG_QTD);
Intent in = new Intent(this,
Edit_linha_prod.class);
in.putExtra("id", id9);
in.putExtra(TAG_DATA, id3);
in.putExtra(TAG_HORA, id5);
in.putExtra(TAG_ESTAB, id4);
in.putExtra(TAG_QTD, id6);
in.putExtra("TAG_ID", id2);
Toast.makeText(getApplicationContext(), id9,
Toast.LENGTH_LONG).show();
Toast.makeText(getApplicationContext(), id2,
Toast.LENGTH_LONG).show();
startActivity(in);
// sending pid to next activity
return true;
on my 2 activity i get the values of this 2 variables but they are the same 637 and 637 instead of 637 and 8
Intent i = getIntent();
// getting product id (pid) from intent
id9 = i.getStringExtra("id");
id3 = i.getStringExtra(TAG_DATA);
id4 = i.getStringExtra(TAG_ESTAB);
id5 = i.getStringExtra(TAG_HORA);
id6 = i.getStringExtra(TAG_QTD);
id2= i.getStringExtra(TAG_ID);
Toast.makeText(getApplicationContext(), id9,
Toast.LENGTH_LONG).show();
Toast.makeText(getApplicationContext(), id2,
Toast.LENGTH_LONG).show();

because you are using the same key for both id9 and id2, which is "id" (notice that the constant TAG_ID has the value of "id" as well), so simply make sure that all of the keys you are using are different.
so your activity 1 should be something like this, (notice that i removed the quotes around the constant TAG_ID)
in.putExtra("id9", id9);
in.putExtra(TAG_DATA, id3);
in.putExtra(TAG_HORA, id5);
in.putExtra(TAG_ESTAB, id4);
in.putExtra(TAG_QTD, id6);
in.putExtra(TAG_ID, id2);
and activity 2 :
id9 = i.getStringExtra("id9");
id3 = i.getStringExtra(TAG_DATA);
id4 = i.getStringExtra(TAG_ESTAB);
id5 = i.getStringExtra(TAG_HORA);
id6 = i.getStringExtra(TAG_QTD);
id2= i.getStringExtra(TAG_ID);

in.putExtra("id", id9);
in.putExtra(TAG_DATA, id3);
in.putExtra(TAG_HORA, id5);
in.putExtra(TAG_ESTAB, id4);
in.putExtra(TAG_QTD, id6);
in.putExtra("TAG_ID", id2);
It looks like you've stored "TAG_ID" as the key here instead of the variable TAG_ID

I am not an expert on JSON-objects, but it seems to me that the php page is not returning the "totaly" part inside your JSON-object. If it instead returned it like this:
{"sales":[{"pid":"1","name":"book of eden","number_to_sale":"2","price":"2.00","total":"4.00","created_at":"2014-02-02 11:31:53"},{"pid":"2","name":"shirt","number_to_sale":"2","price":"500.00","total":"1000.00","created_at":"2014-02-03 14:23:49"},{"pid":"3","name":"mars","number_to_sale":"2","price":"2.00","total":"4.00","created_at":"2014-02-03 21:07:48"},{"pid":"4","name":"shirt","number_to_sale":"1","price":"500.00","total":"500.00","created_at":"2014-02-07 12:05:18"},{"pid":"5","name":"item2","number_to_sale":"4","price":"400.00","total":"1600.00","created_at":"2014-02-12 13:57:49"},{"pid":"6","name":"shirt","number_to_sale":"2","price":"500.00","total":"1000.00","created_at":"2014-02-12 15:42:04"}],"success":1, "totaly":"4108.00"}
Then you could get the "totaly" part like your "success":
int success = json.getInt(TAG_SUCCESS);
String totaly = json.getString(TAG_TOTAL_ALL);

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,

Try this.
Change this line:

to
String id1 = ((TextView) v.findViewById(R.id.pid)).getText().toString();

Delete refresh listview in Android

I have created a list activty1 and an activity2. In the list activity the list is getting populated by the database, on list item selected activity2 is getting called. In activity2 i am updating the values in mysql database. when i am calling back to list activity1 another list item is getting added rather than the list item which was pressed getting updated.
