In Activity WorkDetailsTable , it has a ListView as shown below. When it is clicked, it should display the value on the Add_Details_Information EditText
Assume the first list is clicked, and it intent to Add_Details_Information
Noted that the value on editText was actually get from the second list in Activity A. But what I want is get value accordingly to their position not the latest value.
WorkDetailsTable
int mClickedPosition;
MyCustomBaseAdapter objMyCustomBaseAdapter;

// how to getPosition???

Try this:

final int firstListItemPosition = listView.getFirstVisiblePosition();
final int lastListItemPosition = firstListItemPosition + listView.getChildCount() - 1;
if (pos < firstListItemPosition || pos > lastListItemPosition ) {
return listView.getAdapter().getView(pos, null, listView);
} else {
final int childIndex = pos - firstListItemPosition;
return listView.getChildAt(childIndex);
}
}

This loop return only visible position values.However I need the values of child items that are invisible.
for (int i = 0; i < material_issue_list.getCount(); i++) {
View layout = materialIssueAdapter.getViewByPositio(i, material_issue_list);
LinearLayout listItem = (LinearLayout) materialIssueAdapter.getViewByPositio(i, material_issue_list);
String batchSTR = ((AutoCompleteTextView) listItem.findViewById(R.id.batch_AutoComplete)).getText().toString();
String qtySTR = ((EditText) listItem.findViewById(R.id.issue_qty_ETD)).getText().toString();}
My full adapter class,Some one help me suggest to get the correct output.My problem I'm getting null values from the views that are invisible.
Only the visible values are being updated to arraylist.
Thanks in advance.

You have saveDataArr list which holds all your data.
You can add a getter if you want to do it from an activity , add something like this to your adapter :
private SaveDataModelsendLog(int position) {
return saveDataArr(position);
}
That should do the trick , having said all that you should also look at the difference between static and non-static variables ,
it seems like you have to many of them ,
Enjoy.
I need a little help for the redaction of a class. I want to add some item in my listView, and to do that I use a custom adapter found in this forum, but modified for my use :

In a certain way, it works. But when I swipe the listView too fast, I have this error :
java.lang.NullPointerException: Attempt to invoke virtual method 'void android.widget.TextView.setText(java.lang.CharSequence)' on a null object reference
at com.tanoshi.traveler.doctorgamesfree.cCursorAdapter.bindView(cCursorAdapter.java:57)
at android.widget.CursorAdapter.getView(CursorAdapter.java:254)
at com.tanoshi.traveler.doctorgamesfree.AdvertisingAdapter.getView(AdvertisingAdapter.java:102)
I think it is becausemy listView try to load an item in a view which is not loaded.
How can I do to fix this ?
Thank you for your time.
Here is my adapter code where on edit field edited am calculating the 2 other fields and displaying through TextWatcher. There are 2 issues here.
1. On scroll the values are changing to default values
2. How can I take the new values updated on click of a button
Please help...thanks.

This is because of view recycling. View are recycled with the last state. If your spinner had something selected, and if that view is reused it'll also pick the state of the spinner. You need to add logic to preserve state of your Spinners. You can maintain a dictionary with row position and selectedIndex.
//Class level field
Map<Integer, Integer> myMap = new HashMap<Integer, Integer>();
inside your getView() method check if we have a state saved for the spinner at this row psition
if (myMap.containsKey(position)) {
spinner.setSelection(myMap.get(position));
}
Saving state when an item is selected in spinner
#Override
public void onItemSelected(AdapterView<?> parentView, View v, int selectedIndex, long id) {
//...
myMap.put(position, selectedIndex);
//...
}
Hello Everyone!!
I am making a sample shopping cart in which i need to get the position of item clicked and get the image displayed on the page on selecting the image from the shopping cart..But here i am getting image of first item only no matter i have clicked another..it is always showing first image of the list...

Plz guys Any help will be highly appreciated.
Thanx in advance..
The int position in onItemClick gives the position of the clicked item in the array/list you gave to the adapter.
You can also do getItemAtPosition(); on your listview, if you don't have an easy handle on your original list.
add this code to your Project :
mProductList.setOnItemClickListener(new OnItemClickListener()
{
public void onItemClick(AdapterView<?> parent,
View v, int position, long id)
{
int h = parent.getPositionForView(v);
Toast.makeText(getBaseContext(),
"pic" + (position + 1) + " selected" + h,
Toast.LENGTH_SHORT).show();
}
});
Just geussig that you have a problematic code where you are reading the index value. Following is the sample code for writing and reading int extra:
To put int value:
productDetailsIntent.putExtra(ShoppingCartHelper.PRODUCT_INDEX,
position);
Following code should be used to read this value in another Activity
int index = getIntent().getExtras().getInt(ShoppingCartHelper.PRODUCT_INDEX);
Hope it helps...
