Delete view from ListView - android

i would like to know the best possible way do delete a TextView from ListView,
But i want to do it from Options Menu.
so i click "Delete Country" - it will wait untill i will tap a country than delete the tapped country.
i am new to programming. thanks in advance
public boolean onOptionsItemSelected(MenuItem item) {
switch(item.getItemId()){
case R.id.omAddCountry:
Intent addCountryIntent = new Intent(MainActivity.this, AddCountryActivity.class);
startActivityForResult(addCountryIntent, 11);
break;
case R.id.omDeleteCountry:
break;
the ListView is using SQLite and it gets the first view from DB and the TextViews is added by an Vector from an adapter.
public class CountryAdapter extends BaseAdapter {
private Context mContext;
protected Vector<Country> mVector;
protected SQLiteDatabase mDb;
public void setmContext(Context mContext){
this.mContext = mContext;
}
public CountryAdapter(Context mContext){
this.mContext = mContext;
mVector = new Vector<Country>();
CountryOpenHelper helper = new CountryOpenHelper(mContext);
mDb = helper.getWritableDatabase();
Cursor cursor = mDb.rawQuery("SELECT * FROM COUNTRIES", null);
if(cursor.getCount() > 0){
cursor.moveToFirst();
}
do {
Country country = new Country();
country.setmCountryIndex(cursor.getInt(0));
country.setmCountryName(cursor.getString(2));
country.setmCountryTextSize(cursor.getInt(1));
country.setmCountryColor(cursor.getInt(3));
mVector.add(country);
} while (cursor.moveToNext());
}
public Vector<Country> getmVector() {
return mVector;
}
#Override
public int getCount() {
// TODO Auto-generated method stub
return mVector.size();
}
#Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return null;
}
#Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return 0;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
TextView tv;
if(convertView == null){
tv = new TextView(mContext);
}else{
tv = (TextView) convertView;
}
tv.setText(mVector.get(position).getmCountryName());
tv.setTextColor(mVector.get(position).getmCountryColor());
tv.setTextSize(mVector.get(position).getmCountryTextSize());
return tv;
}
public void ChangeColor(int newcolor, String name) {
mDb.execSQL("update COUNTRIES set color = " + newcolor + " where name = '" + name + "' " );
}
public void addCountry(int mId, String myCountry, int myColorNum){
mDb.execSQL("insert into countries values(" + mId + " , ' " + myCountry+"' , "+ myColorNum + ")");
}
}

Make a global boolean:
boolean isDeleting = false;
then in onOptionsItemSelected(), do:
case R.id.omDeleteCountry:
isDeleting = true;
break;
And whereever you implement onListItemClick():
#Override
public void onListItemClick (ListView listView,View view, int pos, long id)
{
if (isDeleting){
yourCustomAdapter.delete(pos)
yourCustomAdapter.notifyDataSetChanged();
isDeleting = false;
}
else {
//do other stuff
}
}
You will have to make a delete() method in your adapter.

Assign id to new item in listView

This is my activity where it contains listView and an action bar icon.
Everytime the app run, it will go through this method to load the SQLite data to listView.
public void retrieveList(String name) {
database = mdb.getReadableDatabase();
Cursor cursor = database.rawQuery("SELECT * FROM " + MyDatabaseHelper.TABLE__TASK + " WHERE Name = ? ", new String[]{name}, null);
if (cursor != null && cursor.getCount() > 0) {
while (cursor.moveToNext()) {
int iD = cursor.getInt(cursor.getColumnIndex("ID"));
String month = cursor.getString(cursor.getColumnIndex("Month"));
double budget = cursor.getDouble(cursor.getColumnIndex("Budget"));
double totalUsed = cursor.getDouble(cursor.getColumnIndex("Total_Used"));
if (adapter != null) {
adapter.add(iD, month, budget, totalUsed);
listview.setAdapter(adapter);
}
}
}
}
The action bar icon (pen) will open a new dialog. Once the save button clicked, it will add new item to listView.
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.action_add_task:
mClickedPosition = -1;
final AlertDialog.Builder builder = new AlertDialog.Builder(AddMonthlyExpenses.this);
View promptView = getLayoutInflater().inflate(R.layout.dialog_in_addmonthlyexpenses, null);
save = (Button) promptView.findViewById(R.id.okBtn);
month = (EditText) promptView.findViewById(R.id.month);
budget = (EditText) promptView.findViewById(R.id.budget);
alert = builder.create();
alert.setTitle("Add Month ");
alert.setView(promptView);
alert.show();
month.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
showDialog(DATE_DIALOG_ID);
}
});
save.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
String month1 = month.getText().toString();
double budget1 = Double.parseDouble(budget.getText().toString());
if ((month1.trim().equals("")) || (String.valueOf(budget1).trim().equals(""))) {
Toast.makeText(getApplicationContext(), " Not Completed", Toast.LENGTH_SHORT).show();
} else {
adapter.add(id,month1, budget1);
Toast.makeText(getApplication(),id+"",Toast.LENGTH_SHORT).show(); // display 0
insert(name, month1, budget1);
listview.setAdapter(adapter);
alert.dismiss();
//retrieveList(String name)
}
}
}
});
break;
ExpensesAdapter
public class ExpensesAdapter extends BaseAdapter {
private static ArrayList<List> search;
private LayoutInflater mInflater;
ListView listview;
Context context;
double used = 0;
public ExpensesAdapter(Context context, ArrayList<List> searchList, ListView listview) {
this.search=searchList;
this.listview=listview;
mInflater = LayoutInflater.from(context);
this.context= context;
}
public int getCount() {
return search.size();
}
public List getItem(int position) {
return search.get(position);
}
public long getItemId(int position) {
return 0;
}
public void removeItem(int position) {
search.remove(position);
this.notifyDataSetChanged();
}
public void add(int id,String month,double budget,double used)
{
List obj = new List(id,month,budget,used);
this.used=used;
obj.setID(id);
obj.setMonthYear(" " + month);
obj.setBudget(budget);
obj.setUsed(used);
search.add(obj);
this. notifyDataSetChanged();
}
public void add(int id,String month, double budget)
{
List obj = new List(id,month,budget);
obj.setMonthYear(" " + month);
obj.setID(id);
obj.setBudget(budget);
search.add(obj);
this. notifyDataSetChanged();
}
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder =null;
if (convertView == null) {
convertView = mInflater.inflate(R.layout.expenses_adapter, null);
holder= new ViewHolder();
holder.monthAndYear = (TextView) convertView.findViewById(R.id.monthAndYear);
holder.budget = (TextView) convertView.findViewById(R.id.budget);
holder.amount=(TextView)convertView.findViewById(R.id.amount);
holder.progressBar=(ProgressBar)convertView.findViewById(R.id.downloadProgressBar);
holder.balance=(TextView)convertView.findViewById(R.id.balance);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.monthAndYear.setText(search.get(position).getMonthAndYear());
holder.budget.setText("RM" + "" + search.get(position).getBudget());
holder.amount.setText("RM" + "" + search.get(position).getUsed());
holder.progressBar.setProgress((int) search.get(position).getUsed());
holder.progressBar.setMax((int) search.get(position).getBudget());
double a = search.get(position).getBudget();
double b = search.get(position).getUsed();
holder.balance.setText("RM"+""+String.format("%.2f", a-b));
return convertView;
}
static class ViewHolder {
TextView monthAndYear, budget,amount,balance;
ProgressBar progressBar;
}
}
Once the new item is added in listView and I press it, I get id= 0. If I exit the app and click again then only it shows the new id. Is there a way I can make new id assign to new list item instead of exit the app or call the retrieveList method after alert.dismiss(); ?
In your adapter your not setting the id to the obj
public void add(int id,String month,double budget,double used)
{
List obj = new List(id,month,budget,used);
this.used=used;
obj.setMonthYear(" " + month);
obj.setBudget(budget);
obj.setUsed(used);
//Add this line your adapter
obj.setID(id);
search.add(obj);
this. notifyDataSetChanged();
}
public void add(int id,String month, double budget)
{
List obj = new List(id,month,budget);
obj.setMonthYear(" " + month);
obj.setBudget(budget);
//Add this line your adapter
obj.setID(id);
search.add(obj);
this. notifyDataSetChanged();
}
Your getItemId() always returns 0. To match your getItem() try returning something like:
public long getItemId(int position) {
List l = getItem(positon);
return l.getId();
}
Then of course your List must have a getId() which returns a long.
I solved by using this method
change insert(name, month1, budget1); to long id= insert(name, month1, budget1); to get the latest id. Then modify code to this
save.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
String month1 = month.getText().toString();
double budget1 = Double.parseDouble(budget.getText().toString());
if ((month1.trim().equals("")) || (String.valueOf(budget1).trim().equals(""))) {
Toast.makeText(getApplicationContext(), " Not Completed", Toast.LENGTH_SHORT).show();
} else {
long id=insert(name, month1, budget1);
adapter.add(id,month1, budget1);
listview.setAdapter(adapter);
alert.dismiss();
check();
}
}
}
});

Android Listview Item is Repeating on adding new item with different data

i have gone through all the solutions provided on internet . i think i am making some mistake somewhere . if anyone can found where the problem lies...?
i Have noticed only Data[] array is updating with different values. but other String variables are overwriting on every item i add.. why is this happening ?
I think you need to do call notifyDataSetChanged method and before adding data dynamically call ones setAdapter.
or you can go through this link http://androidadapternotifiydatasetchanged.blogspot.in/
okay i have solved it by myself . the problem was i was passing simple string but i have to pass string array in order to add new data to listviews.
here are the changes i made ..
in activity:
public void setlisto(String one ){
Log.e("setlistoo",one+"");
myrows.add(one);
time1.add(Time);
name1.add(Name);
number1.add(Number);
adi = myrows.toArray(new String[myrows.size()]);
adi1=time1.toArray(new String[time1.size()]);
adi2=name1.toArray(new String[name1.size()]);
adi3=number1.toArray(new String[number1.size()]);
listview.setAdapter(new MyNotiAdapter(noticall.this, adi,adi1,adi2,adi3));
// if(adi!=null)
//adp.notifyDataSetChanged();
x++;
}
in baseadapter class :
#Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
ViewHolder mHolder;
View vi = convertView;
if (vi == null){
vi = inflater.inflate(R.layout.row2, null);
mHolder = new ViewHolder();
mHolder.text= (TextView) vi.findViewById(R.id.lablel);
mHolder.Nameo = (TextView) vi.findViewById(R.id.person);
mHolder.Numbero = (TextView) vi.findViewById(R.id.edu);
mHolder.Time = (TextView) vi.findViewById(R.id.tym);
vi.setTag(mHolder);
mHolder.text.setText(data[position]);
mHolder.Nameo.setText(Name[position]);
mHolder.Numbero.setText(Number[position]);
mHolder.Time.setText(time[position]);
}else {
mHolder = (ViewHolder) convertView.getTag();
}
return vi;
}
everything goes smooth now ... its working perfect . it might help someone like me . Cheers..
Your code seems need to be refactored a lot.
Okay First, create an Model Object class, let say MyReminderObject.java :
public class MyReminderObject {
public String date;
public String time;
public String name;
public String number;
}
In your Adapter :
Add a list of MyReminderObject.
private List<MyReminderObject> mList;
Add a new constructor :
public MyNotiAdapter(Context context) {
mList = new ArrayList<MyReminderObject>();
inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
Change some methods :
#Override
public int getCount() {
return mList.size();
}
#Override
public Object getItem(int position) {
return mList.get(position);
}
In your getView method, change some codes :
MyReminderObject item = mList.get(position);
mHolder.text.setText(item.date);
mHolder.Nameo.setText(item.name);
mHolder.Numbero.setText(item.number);
mHolder.Time.setText(item.time);
Still in you adapter, add a function to add item :
public void addReminder(MyReminderObject item){
mList.add(item);
notifyDataSetChanged();
}
In your Activity :
in your onCreate() :
listview.setDividerHeight(5);
adp = new MyNotiAdapter(noticall.this);
listview.setAdapter(adp);
Lastly, on your setListTo() method :
public void setlisto(String one ){
Log.e("setlistoo",one+"");
MyReminderObject newItem = new MyReminderObject();
newItem.date = one;
newItem.time = Time;
newItem.name = Name;
newItem.number = Number;
adp.addReminder(newItem);
x++;
}

A few assumptions here, your actual fields do not need to be ArrayList's since each query returns a single row item from the db, i create a master object with Strings to represent the data...
So here is how i would do it, you need to re structure your data
First i would change your data to a :
public class ParentObject {
public String BILLDATE ;
public String BILLNO ;
public String PARTYNAME ;
public String BILLAMOUNT ;
public String RECEIPT ;
public String BALANCE ;
public String WEEK ;
public String AMOUNT ;
}
UPDATE
then i would change my Activity to:
public class RecordsActivity extends Activity implements OnItemClickListener{
ListView listProduct;
ListAdapter adapter;
TextView UserName,Date;
// your new parent object ArrayList, much cleaner
List<ParentObject> parentObjects;
String get_name,get_date,Name;
String GetAmnt;
Dialog dialog;
AlertDialog alertDialog;
#Override

EndlessAdapter not adding item correctly to custom ListView

Im using the cwac-endless EndlessAdapter with a custom ListViewAdapter. With an AsyncTask i get the data form he webserver in 2 phases.
1) i get all the id's of the elements
2) using the EndlessAdapter i want to load say 4 elements at a time (i get from the server 4 elements by their id)
The problem that im facing is that as i create my custom ListViewAdapter when i call the contructor of MyEndlessAdapter which creates the list of items with the first bach of items. when i load the next batch of elements my custom ListViewAdapter it gets the correct items from the server but i recycles the getView(graphic/visual stuff). What am i doing wrong!
I think a possible solution bwould be to use the add method of the CustomListView but i dont know how to call it from the CompraFragment class.
How do i solve this problem?
Thanks

When a view is recycled [i.e., passed to getView() as a non-null convertView], you need to update it to reflect the state of the current item. So, the 2 lines indicated below need to be moved after the if/then block.
public View getView(final int position, View convertView, ViewGroup parent) {
Item item = items.get(position);
Log.w(TAG, "view of Item " + item.getId() + " at position " + position);
ItemView view;
if (convertView == null) {
inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view = (ItemView) inflater.inflate(R.layout.listview_item_row, null);
Log.e(TAG, "CREATED ITEM " + item.getId() + " at position " + position);
} else {
view = (ItemView) convertView;
Log.i(TAG, "RECYCLED ITEM " + item.getId() + " at position " + position);
}
// ===> These 2 lines always need to be executed. <===
view.checkFollowing(item, this, 3);
view.setTag(Long.toString(item.getId()));
view.setOnClickListener(new OnItemClickListener(position));
view.showItems(item);
return view;
}

Spinners selection changes on adding new items or scrolling listview android

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);
//...
}
