Update Listview in Fragment , based on activity result . No result found anywhere

I have an activity and a fragment
In my activity i have button in my action bar ,on button click a dialog box is popup , in that i have a listview.
If i select any item from that list , that data goes to fragment , and based on that data from activity my fragment listview should be shown
e.g. if i select Technology , technology id =1 should pass in my query parameter and based on that my fragment listview should appear.
everytime i select different item from list my fragment listview should be updated.
But my problem is that i am not getting any data in fragment and my list is not getting updated
Mainactivity.java
#Override
public boolean onPrepareOptionsMenu(Menu menu) {
MenuItem actionViewItem = menu.findItem(R.id.miActionButton);
// Retrieve the action-view from menu
View v = MenuItemCompat.getActionView(actionViewItem);
// Find the button within action-view
Button b = (Button) v.findViewById(R.id.btnCustomAction);
// Handle button click here
b.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
showDialog(CUSTOM_DIALOG_ID);

Log.d("id",""+cat_id);
dismissDialog(CUSTOM_DIALOG_ID);
}
});
break;
}
return dialog;
}
public int getMyData() {
return cat_id;
}
Fragment.java :
public String param;
public String url;
public int cat_id;
Mainactivity activity = (Mainactivity) getActivity();
int myDataFromActivity = activity.getMyData();
cat_id = myDataFromActivity;
Log.d("Category_id", "" + cat_id);
Map<String, String> map1 = new HashMap<String, String>();
param = "?cat_id=" + cat_id;
//URL is fake , original url is working fine.
url = "http://www.abbcd.com/xyz/webservices/data/getAllData.php"
+ param;
map1.put("url", url);
new MultiPartRequester(mainActivity, map1,
NetUtils.RequestCode.GET_ALL_DATA,
this).execute();
Updated Part :
#Override
public void updateFragmentList(int catId) {
// TODO Auto-generated method stub
param = "?cat_id=" + catId;
url = "http://www.abbcd.com/xyz/webservices/data/getAllData.php"+ param;
Map<String, String> map1 = new HashMap<String, String>();
map1.put("url", url);
new MultiPartRequester(mainActivity, map1,
NetUtils.GET_DATA, this)
.execute();
}

The good approach for communication between Activity and Fragment is Listeners. When you want to update fragment, use the listener and update the fragment. Create the interface in MainActivity
Listener
public interface FragmentListener {
void updateFragmentList(int catId);
}
Implement in Fragment as
public class MyFragment extends Fragment implements MainActivity.FragmentListener
then in onActivityCreated of Fragment
#Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
((MainActivity) getActivity()).setFragmentListener(this);
}
MainActivity
public void setFragmentListener(FragmentListener listener)
{
this.fragmentListener = listener;
}
public void sendDataToFragment(int catId) {
this.fragmentListener.updateFragmentList(catId);
}
Hope this helps.
UPDATE
Sending data to fragment using this.fragmentListener.updateFragmentList(catId);, create the method in Fragment as ``
public void updateFragmentList(int catId){
//Here update your listview with cat id
}

use static global variable in activity
public static int cat_id = 0;
access cat_id in fragment like below
Map<String, String> map1 = new HashMap<String, String>();
param = "?cat_id=" + activity.cat_id;
or do below changes in your getMyData method
public int getMyData() {
return cat_id;
}
EDITED:
another approach finally work, call your fragment method from activity ans pass cat_id in method. instead of ExampleFragment use your fragment name.
ExampleFragment fragment = (ExampleFragment) getFragmentManager().findFragmentById(R.id.example_fragment);
fragment.mymethod(cat_id);

Can't Create Table With 4 Column SQLite Android Studio

i am a very very dumb newbie in Android Programming,
here i want to make a Cashflow note app in android studio.
In this case i want to create a table call Category_Table with 4 column called CategId, CategName, Note and Currency.
I have doing the tutorial from google and etc extacly. But till now i still have this problem.
When i want to insert some data into Category_Table, it says No Column named Currency in Android Studio report.
I dont know what to do, i have googling it but still cant solve this problem.
Please gimme an answer that i can understand as a newbie programmer.
Thanks.
NB. Here is my code:
Add_Category code :
public class AddCategory extends ActionBarActivity {
private static Button BtnIAdd;
private static Button BtnICancel;
EditText txtcategname, txtnote;
Spinner selectCurrency;

DatabaseHelper myDB;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_add_category);
myDB = new DatabaseHelper(this);
txtcategname = (EditText)findViewById(R.id.editText);
txtnote = (EditText)findViewById(R.id.editText2);
BtnICancel = (Button)findViewById(R.id.btnCancel);
BtnIAdd = (Button)findViewById(R.id.btnAdd);
//spinner
selectCurrency = (Spinner) findViewById(R.id.spin_selectCurrency);
adapterCurrency = ArrayAdapter.createFromResource(this, R.array.CurrencyName,android.R.layout.simple_spinner_item );
adapterCurrency.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
selectCurrency.setAdapter(adapterCurrency);
selectCurrency.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
Toast.makeText(getBaseContext(), parent.getItemAtPosition(position)+" selected",Toast.LENGTH_LONG).show();
String currencyValue = String.valueOf(parent.getSelectedItem());
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
addCategData();
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_add_category, menu);
return true;
}
public void addCategData(){
BtnIAdd.setOnClickListener(
new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(AddCategory.this,"Clicked", Toast.LENGTH_LONG).show();
boolean isInserted = myDB.insertCategData(txtcategname.getText().toString(),
txtnote.getText().toString(), selectCurrency.getSelectedItem().toString());
if (isInserted == true)
Toast.makeText(AddCategory.this,"Inserted", Toast.LENGTH_LONG).show();
else
Toast.makeText(AddCategory.this,"Not Inserted", Toast.LENGTH_LONG).show();
}
}
);
BtnICancel.setOnClickListener(
new View.OnClickListener() {
#Override
public void onClick(View v) {
finish();
}
}
);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
And this one for DatabaseHelper Class
public class DatabaseHelper extends SQLiteOpenHelper {
public static final String MyVillageSoftware = "MyVillageSoftware";
public static final String DATABASE_NAME = "Cashflow.db";
public static final String TABLE_Categ_NAME = "category_table";
public static final String COL1 = "CategId";

return true;
else
return false;
}
public ArrayList<String>getAllCategory(){

SQLiteDatabase db = this.getReadableDatabase();
String selectCateg="Select * FROM " +TABLE_Categ_NAME;
Cursor cursor = db.rawQuery(selectCateg, null);
if(cursor.getCount()>0){
while (cursor.moveToNext()){
String categname=cursor.getString(cursor.getColumnIndex(COL2));
AllCategoryList.add(COL2);
}return AllCategoryList;
}
return AllCategoryList;
}
#Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
db.execSQL("DROP TABLE IF EXISTS " +TABLE_Categ_NAME);
onCreate(db);
thanks before... :)

1) Uninstall the App and Install again.
2) issue is "No Column named Currency in Android Studio report" this is because column currency might be added after table created. so for that you have to define Database Version(an integer value e.g. Ver=1) and change the version of DB whenever you do changes in database(increase that int value e.g. Ver=2) so it will call onUpgrade() and drop your tables and create it again. this will solve your problem.
EDIT: You have given that Database version 1 as default in super(context,dbName,cursorFactory,dbVersion)
public DatabaseHelper(Context context) {
super(context, DATABASE_NAME, null, 1);
}

This code is working fine on my phone galaxy note 2(custom rom of note 4.. Android 4.4.4).By fine I mean I can type in edittext and popupwidow shows up after 3rd text(because of condition I have put) and I can select an option from the popupwindow. When I try to run the code on any other phone like galaxy grand then callback to ItemsDropdownOnItemClickListener is not registered and I can only scroll the popupwindow and keep on typing in edittext but cannot select any of the options in the popupwindow. If I set popupWindowItems.setFocusable(false) to true i.e popupWindowItems.setFocusable(true), and then as soon as I type 3rd letter in edittext,edittext looses focus and popwindow gains it. Now I can select anything.. But now I cannot continue to type in edittext.I have to manually select edittext and type.
Now I want that after tying 3rd word in edittext a popupwindow should appear(which currently is appearing) and edittext doesn't loose focus(so that i can continue typing).. Further if I select anything from popupwindow ,ItemsDropdownOnItemClickListener should be called which is currently being not called in other phones when popupWindowItems.setFocusable(false);
I am doing this to load data from sqlite database and show in popupwindow once the user types 3rd word. Any suggestion is recommended
Edit: Problem solved. Now using AutoComplete TextView

Passing data between fragments and the next activity

Firstly, this is my first question here, Thanks for any reply:)
I have a fragment extends SherlockListFragment that has a list of (events) saved in database, i want when i click on any item in the list , to get all event data and fill in another activity that has editText(s) ....
this is the frgment.java code
public class EventsFragment extends SherlockListFragment {
EditText _eventName_;
EditText next_activty_text;
List<String> presidents = new ArrayList<String>();
public DBAdapter db;
String buf = "";
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_events, container, false);
_eventName_ = (EditText) v.findViewById(R.id.editText11);
next_activty_text = (EditText) v.findViewById(R.id.editText12);
// The most Important part in action bar menus :)

You have two choices. Either fetch the data from your database in EventsFragment.onListItemClick(), and pass that data to your second Activity as Intent extras. Or you can pass the id of the clicked item, and do the database operations in your second Activity. Either way you have to pass data using Intents
public class EventsFragment extends SherlockListFragment {
.
.
#Override
public void onListItemClick(ListView l, View v, int position, long id) {
Intent intent = new Intent(this, CreateEventActivity.class);
// OPTION 1: Fetch data here, and pass it with the intent
db = new DBAdapter(getActivity());
db.open();
Cursor c = db.getEvent(id+1);
intent.putExtra("id", c.getString(1));
intent.putExtra("event_name", c.getString(2));
// Do this for all your values.
db.close();
startActivity(intent);
// OPTION 2: Pass the id of the selected item, and fetch the data in second activity
intent.putExtra("selected_id", id+1);
startActivity(intent);
}
}
In CreateEventActivity you then have to get the extras you chose to pass with the Intent.
#Override
protected void onCreate(Bundle savedInstanceState) {
.
.
Intent intent = getIntent();
// If you chose option 1, you have to get all the extras you attached to the Intent.
long id = intent.getLongExtra("id", -1)
String eventName = intent.getStringExtra("event_name", "defValue");
// Fetch all the values here..
// If you chose option 2, you fetch the id and do the database operations to retrive
// the data
long id = intent.getLongExtra("selected_id", -1);
// DB stuff here..
}

ListView not updating after inserting data through an Android DialogBox?

hi all Am having listview which displays list of items from sqlite db. Using DialogBox am inserting data in DB. Insertion done successfully. But if i entered data on DialogBox and click ok button, the data inserted in db but the inserted data is not displaying in ListView.
ListView is not refreshing.... I hv used adapter.setNotifyOnChange(true);. But this wont take any effect on listview.
And I have got warning on logcat as
`09-16 15:01:10.215: INFO/dalvikvm(2066): Uncaught exception thrown by finalizer (will be discarded):
09-16 15:01:10.215: INFO/dalvikvm(2066): Ljava/lang/IllegalStateException;: Finalizing cursor android.database.sqlite.SQLiteCursor#44c4be28 on PAYMENT_TABLE that has not been deactivated or closed

But i hv closed the cursor in OnDestory()
Here is my code.
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
mySQLiteAdapter = new SQLiteAdapter(this);
mySQLiteAdapter.openToWrite();
cursor = mySQLiteAdapter.queueAll();
cursor.moveToFirst();
while(!cursor.isAfterLast()) {
String mTitleRaw = cursor.getString(cursor.getColumnIndex(SQLiteAdapter.KEY_PAYMENT_TYPE));
al.add(mTitleRaw);
cursor.moveToNext();
}
adapterChanged();
}
#SuppressWarnings("unchecked")
private void adapterChanged() {
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_multiple_choice, al);
adapter.setNotifyOnChange(true);
setListAdapter(adapter);
listContent = getListView();
listContent.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
}
#Override
protected void onListItemClick(ListView l, View v, int position, long id) {
// TODO Auto-generated method stub
super.onListItemClick(l, v, position, id);
//Object o = this.getListAdapter().getItem(position);
}
#Override
protected void onDestroy() {
// TODO Auto-generated method stub
super.onDestroy();
if (mySQLiteAdapter != null) {
mySQLiteAdapter.close();
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// TODO Auto-generated method stub
menu.add(0, MENU_ADD, 0, "Add New");
return super.onCreateOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// TODO Auto-generated method stub
switch(item.getItemId()) {
case MENU_ADD:
AlertMsg();
return true;
}
return super.onOptionsItemSelected(item);
}
private void updateList(){
cursor.requery();
}
public void AlertMsg() {
AlertDialog.Builder alert = new AlertDialog.Builder(this);
alert.setTitle("Payment Type");
alert.setMessage("Add field");
final EditText mTxt = new EditText(this);
alert.setView(mTxt);
alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
String mNewField = mTxt.getText().toString();
//Toast.makeText(getApplicationContext(), "Item " + mNewField + " Added", Toast.LENGTH_LONG).show();
mySQLiteAdapter.insert(mNewField);
updateList();
adapterChanged();
}
});
alert.show();
}
}
Are this efficient way....
Can anyone pls give some suggestions.....
Thanks......
