Android: Deleting a row from SQLite table and updating a ListView
If you are using the SQLiteOpenHelper you should be getting a SQLiteDatabase object and then using a transaction, if you don't set it as successful then nothing will happen SQLiteDatabase db = mDbHelper.getWritableDatabase(); db.beginTransaction(); //Do stuff db.setTrasactionSuccessfull(); db.endTransaction(); Also I think when you pass null into the where clause the where doesn't matter. You should have something like db.delete("tbl", "id=?", new String[]{String.valueOf(id)});

Android Adapt Data from a SQLite Database to a Listview
Not with the same amount of values, 5000 but I had a similar problem. I ended up using a private arrayList on a ListAdapter, the list will contain only partial lists, for example 100 items. Your cursor can initially contain the values to fill the firsts 100 items and when you scroll down looking for more items you can launch another cursor to retreive the next 50 items. Controlling a range of 100-150 items at your arrayList by adding/removing new/old items and refreshing the adapter. I vote up your question because maybe someone find a better way to do it and I would like to know as well.

Text values are changed in customized listview when scroll the listview in android?
The problem is that you are not using a different view holder for every line, and that when recycling your list item views your holders are shuffled togheter. You can see this simply adding a final int position field to your holder, where to store the getView position parameter; debugging, you will see what happen. So, you can't use holders to store your quantity values Furthermore, you are not using the variable list to store quantity values. This code is working for me: public View getView(final int position, View convertView,final ViewGroup parent) { final ViewHolder holder; LayoutInflater inflater = activity.getLayoutInflater(); if (convertView == null) { convertView = inflater.inflate(R.layout.order_custom, null); holder = new ViewHolder();

In android layout how do I align elements underneath a listview regardless of the listview's height
It sounds like you've used android:layout_below="@id/listVieId" and android:layout_alignParentBottom="true" as these would give the results you mentioned. It sounds like what you want is addFooterView(View v) Note what the Docs say NOTE: Call this before calling setAdapter. This is so ListView can wrap the supplied cursor with one that will also account for header and footer views.

listview with simpleadapter not refreshing after adding new data to sqlite database
After modifying the data set that is connected on the adapter you must call notifyDataSetChanged to notify the adapter to update the views with the new data. You must also call requery on the Cursor to update the cursor with new data. To clarify you should call requery before notifyDataSetChanged. Check sample code below public class WeatherAppActivity extends ListActivity { Button buton; ItemsAdapter lista; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); List<String> initialList = new ArrayList<String>(); initialList.add("Bucuresti"); initialList.add("Sibiu"); lista=new ItemsAdapter(this, initialList); buton=(Button)findViewById(R.id.button1); buton.setOnClickListener(new OnClickListener(

At getView() check if you need this view, if so, set its visibility to be 'visible' otherwise, set 'gone ' (you must set the visibilty for every list item even if you believe that you don't have to do so).

Null Pointer Exception while retrieving data from SQLite and displaying in listview
There are two things. First is your array initialization. The line String[] values = {}; creates an empty array without allocated memory. You need to initialize an array with the size to hold all elements you are going to store in the array. e.g. after the query do String[] values = new String[c.getCount()]; Then it seems you are calling c.moveToNext() too often. Once in your for loop and then in the surrounding do-while. Simply do something like while (c.moveToNext()) { values[i] = c.getString(c.getColumnIndex("PersonName")); i++; }

How android sqlite databse will update in android market?
I have a better solution for this problem. It will be better if you host a web service that will serve the update information. You can do it for free. GoogleAppEngine provides this feature. Serve JSON file from web, parse it in you application. Each time your app launches, write code to check for update information. OR check once in week or some other strategy. This might be tougher way of doing but you can provide more efficient and flexibility through this.
