I created a SQLiteDatabase where I can see the items with the 'View' Button and clicking on it, I get the whole database into a ListView. In this ListView I would like the items to be clickable and if I click on them, I want to add a new entry to it with the same name, but another id. My code so far:
ListView lv;
ArrayList<String> todoItems = new ArrayList<String>();
#Override
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setListAdapter(new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1, todoItems));
ListView lv = getListView();
lv.setTextFilterEnabled(true);
hornot info = new hornot(this);
info.open();
Cursor c = info.getAllTitles();
if (c.moveToFirst())
{
do{
todoItems.add(c.getString(0) + " " + c.getString(1) + " " + c.getString(2));
}while (c.moveToNext());
}
if (todoItems.size() > 0)
{
lv.setAdapter(new ArrayAdapter<String>(sqview.this,android.R.layout.simple_list_item_1, todoItems));
}
lv.setOnItemClickListener(new OnItemClickListener(){
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
//-/////////////////////////
}
});
info.close();
}
As you see, I put the database items into an array, then I put them into a ListView. With an upgrade button I can add items, so I think I need to do something same here.
In the dbhelper the createEntry function:
public long createEntry(String name, String hotness) {
ContentValues cv = new ContentValues();
cv.put(KEY_NAME, name);
cv.put(KEY_HOTNESS, hotness);
return ourDatabase.insert(DATABASE_TABLE, null, cv);
}
In the main.java I convert the EditTexts to Strings then put the values into the database:
String name = sqlName.getText().toString();
String hotness = sqlHotness.getText().toString();
hornot entry = new hornot(dbhelp.this);
entry.open();
entry.createEntry(name, hotness);
entry.close();
So what should I write for the onItemClick function?
In the onItemClick() method you have the position parameter that indicates the position(in the adapter) of the list row that was clicked. You could then use getItemAtPosition on the ListView to get the data from the row:
lv.setOnItemClickListener(new OnItemClickListener(){
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
String rowData = (String) lv.getItemAtPosition(position); //you'll need to make the lv as final
String[] data = rowData.split(" "); //split the result using the spaces (so you could obtain the name, hotness and the other string you use)
entry.createEntry(data[0], data[1]);
}
I don't know your database structure so I can't recomend you something about unique id.

I am using an sqllite database to store two columns which are phonename and phonenumber. I am using an arrayList to iterate through the data and display the phonename in a listview which is working, but I also need to iterate through the phonenumber column under the same listview as well. I only need the phonename to be showing in the listview.
This is for when the user has selected the item in the listview, it shows the selected phonename and phonenumber, which at the moment it is only currently showing the phonename and showing blank for phonenumber for obvious reasons.
DataDBAdapter
public long insert(String phonename, String phonenumber)
{
ContentValues cv = new ContentValues();
cv.put(COl_MYTABLE_PHONENAME,phonename);
cv.put(COL_MYTABLE_PHONENUMBER,phonenumber);
return mDB.insert(TBL_MYTABLE,null,cv);
}
//---------------------------------------------------------------------------
// Iterating through the database
//---------------------------------------------------------------------------
public ArrayList<String> getAllRowsAsList()
{
Cursor csr = mDB.query(TBL_MYTABLE,null,null,null,null,null,null);
ArrayList<String> rv = new ArrayList<>();
while (csr.moveToNext())
{
rv.add(csr.getString(csr.getColumnIndex(COl_MYTABLE_PHONENAME)));
}
return rv;
}
SelectModemFragment
private void manageListView(Context context)
{
thelist = dbHelper.getAllRowsAsList(); // Extract the list, just the phone names
// Only setup the adapter and the ListView if the adapter hasn't been setup
if(arrayAdapter == null)
{
// Instantiate the adapter
arrayAdapter = new ArrayAdapter<>(context,android.R.layout.simple_list_item_1,thelist); //<<<<<<<<<< list included
display_contacts1.setAdapter(arrayAdapter); //<<<<<<<<<< Tie the adpater to the ListView
// Set the ListViews OnItemClick Listener
display_contacts1.setOnItemClickListener(new AdapterView.OnItemClickListener()
{
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id)
{
String namedisplay = arrayAdapter.getItem(position); //<<<<<<<<<< this gets the phone name
namedisplay = arrayAdapter.getItem(position);
Toast.makeText(view.getContext(), namedisplay + " Selected for Communication", Toast.LENGTH_SHORT).show();
Toast.makeText(view.getContext(), phoneNo, Toast.LENGTH_SHORT).show();
}
});
}
Issue
using ArrayAdapter only allows a a single item to be passed, thus unless you resort to complicated/messy/inefficient methods ArrayAdapter is only really suitable for a single value.
Fix
You could use an ArrayList where your_object has members for all the required values. i.e phonenumber and phonename. Noting that unless you use a Custom Adapter that you should override the the toString method to extract the data that you want to be displayed, as that is what a standard ArrayAdapter uses.
Alternative (use a CursorAdapter)
An alternative would be to use a Cursor Adapter (e.g. SimpleCursorAdapter), you can then return the Cursor and use it directly. However, a CursorAdapter REQUIRES a column specifically name _id (BaseColumns._ID can be used).
One of the clear advantages of a Cursor adapter is the the 4th paremmter passed to the onItemClick/onItemLongClick is the id of the row (if used correctly) allowing a single value to then get/update/delete/pass the respective selected row.
As such I'd recommend a Cursor Adapter for a ListView and hence the more comprehensive answer.
You may think I don;t have such a column. However, you can use the normally hidden rowid column and dynamically create a column named _id.
You could have a method, in the database helper (DataDBAdapter) such as :-
public Cursor getAllRowsAsCursor()
{
String[] columns = new String[]{"rowid AS " + BaseColumns._ID,"*"}
return = mDB.query(TBL_MYTABLE,null,null,null,null,null,null)
}
The ManageList method could then be :-
private void manageListView(Context context) {
myCursor = dbhelper.getAllRowsAsCursor();
// Only setup the adapter and the ListView if the adapter hasn't been setup
if(arrayAdapter == null)
{
// Instantiate the adapter
arrayAdapter = new SimpleCursorAdapter(context,android.R.layout.simple_list_item_1,myCursor,new String[]{DataAdapter.COl_MYTABLE_PHONENAME},newint[]{android.R.id.text1},0);
display_contacts1.setAdapter(arrayAdapter); //<<<<<<<<<< Tie the adpater to the ListView
// Set the ListViews OnItemClick Listener
display_contacts1.setOnItemClickListener(new AdapterView.OnItemClickListener()
{
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id)
{
String namedisplay = arrayAdapter.getItem(position); //<<<<<<<<<< this gets the phone name
String phonenumber = myCursor,getString(myCursor.getColumnIndex(DataAdapter.COL_MYTABLE_PHONENUMBER);
Toast.makeText(view.getContext(), namedisplay + " Selected for Communication", Toast.LENGTH_SHORT).show();
Toast.makeText(view.getContext(), phonenumber, Toast.LENGTH_SHORT).show();
}
});
} else {
arrayAdapter.swapCursor(myCursor);
}
Notes
MyCursor would be declared as a class variable e.g. Cursor MyCursor;
Instaed of
ArrayAdapter<String> arrayAdapter; you would have
SimpleCursorAdapter arrayAdapter;
The above is in-principle code and has not been tested, so there may be errors and/or omissions.
Working Example
The following is the code based upon the code from the previous question asked (which this appears to follow on from). It has two ListViews the old and a new one that uses a SimpleCursorAdapter. Clicking an item display phone number and also id. Lon Clicking an Item deletes that item (refreshing both ListViews).
DataDBAdapter.java has two new methods (so add these) :-
//<<<<<<<<<< ADDED
public Cursor getAllRowsAsCursor() {
return mDB.query(TBL_MYTABLE,null,null,null,null,null,null);
}
public int delete(long id) {
String whereclause = COL_MYTABLE_ID + "=?";
String[] whereargs = new String[]{String.valueOf(id)};
return mDB.delete(TBL_MYTABLE,whereclause,whereargs);
}
SelectModemFragment.java is now :-
public class SelectModemFragment extends Fragment {
private SelectModemViewModel mViewModel;
ListView display_contacts1;
ArrayAdapter<String> arrayAdapter;
ArrayList<String> thelist;
DataDBAdapter dbhelper;
//<<<<<<<<<< ADDED

Hi I have been working through several different tutorials on getting data from a sql database into a listview. I can add data, get data from database and populate the list view, and have a working onclick listener (will fire off a Toast message). However I can not get any data from the listview when clicked. I have tried different combinations of getitem and getItemAtPosition but they all return a empty string(blank toast). Would someone be kind enough to look at my code and tell me if what I am trying to do is possible. In my listview i have four items in each entry, I would like to either get the fourth item directly or get all the items (as string?) then I can pull out the data I need.
Thanks in advance for your time.

try to change the line
String text = (String) LISTVIEW.getItemAtPosition(position);
with
String text = (String) parent.getItemAtPosition(position);
this should be the way ListView works.
Also i suggest you to not use Capital Cases with variables, usually in Java is used a CamelCase convention. And also have a look at RecyclerView, that usually is implemented today much more than ListView, because allow a great level of customization
Pls use below code within listview setOnItemClickListener :-
String genreID = ID_ArrayList.get(position);
String genre = GENRE_ArrayList.get(position);
String genreName = NAME_ArrayList.get(position);
String genreUrl = URL_ArrayList.get(position);
Toast.makeText(getApplicationContext(), genreID+", "+genre+","+genreName+", "+genreUrl+", "+, Toast.LENGTH_SHORT).show();
its return render data of listview.
try this,
ShowSQLiteDBdata() in onCreate() instead of onResume() method
this is a succesor to this question
At first everything worked fine but after 2 deletes the misery starts. The database entries start with ID 1, then 2 and so on. Lets say I have three database entries. The listview IDs for these three entries are 2,1 and 0.
The database entries are 1,2 and 3. 1 and 2 will be deleted with the onitemclicklistener but since the listview doesn´t have an ID 3, the corresponding database entry will never ever be deleted.
So the question is, how can I "sync" those two IDs?

If you need more code just let me know :)
You have no synchronicity between your Database and the ListView items.
When selecting the data, select the ID from the table, and keep it in memory as well.
Since vorgangsdaten looks german or sweden, I am having trouble understanding the meaning of those words. The ListView has its own "id" for each item, to keep a list of them shown, and the rest "hidden". What you must do is have an Object with details that are syncronized with the database, and when a list item is clicked, the "list id" is used to query an Object and delete from the database.
An example would be:
ArrayList<MyObject> arrayListData = new ArrayList<>();
ArrayList<String> arrayListNames = new ArrayList<>();
MyObject stuffs = database.query(); // In here, fetch the data
/* I am simplifing the MyObject to [String name, String aValue, int aNumber] */
for(MyObject s: stuffs){
arrayListData.add(s);
arrayListNames.add(s.name);
}
arrayAdapter = new ArrayAdapter<String>(
this,
android.R.layout.simple_list_item_1,
arrayListNames
);
listView.setOnItemClickListener(
new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
MyObject thing = arrayListData.get(position);
database.delete(thing.aNumber);
}
}
);
listView.setAdapter(arrayAdapter);
After trying Bonattis answer and experimenting a little bit I found another answer.
deleteRow-Method
public void deleteRow(long id){
String s_id; //String for long id
s_id = String.valueOf(id); //assign String value of id
String s_rowId = null; //String for rowid
long rowId = 0;
long deleteId = 0;
String s_deleteId = null;
Log.d(s_id,"id_value");
Cursor cursor = database.query(VorgangDbHelper.TABLE_VORGAENGE_LIST,columns,null,null,null,null,null);
if(cursor.moveToFirst()) {
s_rowId = cursor.getString(cursor.getColumnIndex(VorgangDbHelper.COLUMN_ID));
rowId = Long.parseLong(s_rowId);
deleteId = rowId + id;
s_deleteId = String.valueOf(deleteId);
Log.d(s_rowId,"rowID");
Log.d(s_deleteId,"deleteID");
}
database.delete(VorgangDbHelper.TABLE_VORGAENGE_LIST,VorgangDbHelper.COLUMN_ID + " = ?", new String[] {s_deleteId});
}
How does it work now?
So the deleteRow-Method(dRM) gets the id of the first database entry (s_rowId) and converts it to long (rowId).
Now I take the long id passed from the listview and add it to rowId which is my deleteId. With this I have the correct database value to what I clicked in the listview and can pass it over to database.delete
I managed to show a list from sqllite, now I want that when the user click on the item, the item will be deleted. the problem is that the item's ID number from the sql is different from the listview's ID. so how can I delete the selected item?
I mean this id:
public void onItemClick(AdapterView parent, View view,int position, long id)
is different from the item's ID from the sqllite.
thank you for help

// how to delete? =[
}});
Would it not be easier to make an object that you fill with the data from your sql query for each entry? Then you just populate the listview with a list of these objects, which means that when one of the objects get clicked on the id will be stored inside the object. Then int position would have the same value as the position in your list of objects.
How does that sound?
i have a problem with my list view, i display an item and subitem , i want to insert the two in database but it doesn't work !! the error is that i can't cast it to a text view
please someone help me.
This is the error that i get :
java.lang.ClassCastException: android.widget.TwoLineListItem cannot be cast to android.widget.TextView
Here the code of List View :
String[] databaseColumnNames = new String[] { DBAdapter.col_N_Ordre,DBAdapter.col_Nom_prénom};
int[] toViewIDs = new int[] { android.R.id.text1,android.R.id.text2 };
SimpleCursorAdapter myCursordapter = new SimpleCursorAdapter(this,android.R.layout.simple_expandable_list_item_2 , cursor, databaseColumnNames, toViewIDs);
ListView list = (ListView) findViewById(android.R.id.list);
list.setAdapter(myCursordapter);
Here the code of insertion :
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(final AdapterView<?> arg0, View arg1,
final int position, long arg3) {
Toast.makeText(getApplicationContext(), " " + position, Toast.LENGTH_LONG).show();
final String s = ((TextView)arg1).getText().toString();
db.insertest(s);
The query is :
public long insertest(String region) {
ContentValues initialValues = new ContentValues();
initialValues.put(col_Region,region);
//initialValues.put(col_Provence_prefecture );
return db.insert(MENAGE,null, initialValues);
}
Put following code in your listview item click listener
TextView v1 = (TextView)arg1.findViewById(android.R.id.text1);
String first = v1.getText().toString();
TextView v2 = (TextView)arg1.findViewById(android.R.id.text2);
String second = v2.getText().toString();
ContentValues cv = new ContentValues();
cv.put(DBAdapter.col_Region, first);
cv.put(DBAdapter._id, second);
myCursordapter.notifyDataSetChanged();
list.setAdapter(adapter);
DBAdapter sql_Adapter = new DBAdapter(context);
sql_Adapter.open();
db.insertest(cv);
sql_Adapter.close();
