My current application has a Listview which pulls and displays data from a sqlite DB. Data in the first column of the DB is displayed in the listview and when clicked, an activity starts showing the rest of the column associated with the first column. When the data is edited, the DB updates but the listview does not show the updates unless the application is restarted.
I fetched data in JSON from web service and then i put data into a custom ListView.
On clicking an item of ListView , I open a new Activity.
In my main activity I want to override the onResume method so it acts differently, depending on the activity, which was opened before.
For example: if the user creates a new Item for the listView (in the addNewItem activity), I need to reload the database to display the newItem.
Im new to android. Im trying to do a simple database project. I have a two problems with my project. I have try in many ways but i cant solve it. My problems are
1) I want to pass a string value from first activity to second activity and in both activity string value i should get in third activity.
New to Android and I'm having an issue with updating my a ListView after deleting entries from a database.
In my activity I have a ListView with multiple choice checkboxes in each row. After the user presses a delete button, deleteName() gets called. deleteName() will then delete any Names that were checked in the ListView. The Names get deleted from the database, but the ListView never update.
I have a listview that uses a custom arrayadapter that loads a layout with text + a radiobutton. The user should only be able to select a single item in the list at a time - so basically only one radio button should be 'checked' at any time. This works perfectly except when the activity is recreated, like when the screen is rotated.
i am stuck while developing my program.
i am not able to find the solution
what i am doing is, from one activity (A) i am calling other activity (B) for result.
now in activity A i have a list view.
for that listview i have an ArrayAdapter
the code for that purpose is :
String []name_list = myarraylist.toArray(new String[myarraylist.size()]);
ArrayAdapter<String> adapter = new ArrayAdapt
I have a custom listview implementation in which i have overridden the onScroll and onLongPress. Both the methods return true indicating that the event was handled so that no other event gets fired.
While using this listview in my activity i register the listview for ContextMenu using registerForContextMenu.
I've done my homework; I know all the ways to query an SQLite db from an Activity.
The problem is that all the examples ASSUME that i want to "load" data from the db onto the FIRST Activity screen.
But when my app's FIRST Activity is loaded I DON'T WANT TO GET ANY DATA FROM THE DB; i just want to:
(1) Check if the db file has already been created (if the setup routines have already run).
(2) I
