i have problem with search, when user type something, listview will change, so the next activity will recive wrong values.
my code:

setContentView(R.layout.search);
// Listview Data
String products[] = getResources().getStringArray(R.array.search);
lv = (ListView) findViewById(R.id.list_view);
inputSearch = (EditText) findViewById(R.id.inputSearch);
// Adding items to listview
adapter = new ArrayAdapter<String>(this, R.layout.list_item, R.id.subject_name, products);
lv.setAdapter(adapter);
/**

inputSearch.addTextChangedListener(new TextWatcher() {

int position, long id) {
final String item = lv.getItemAtPosition(position).toString();
int total_number = 50;
for(int x = 1; x < total_number+1; x = x+1) {
String SubjectName = "subject_" + String.valueOf(x);
int resID = getResources().getIdentifier(SubjectName, "string", getPackageName());
String subject = getResources().getString(resID);
if(item.equals(subject)) {
String StringClass = "com.example.finaltest.Subject_" + String.valueOf(x);
Class<?> c = null;
if(StringClass != null) {
try {
c = Class.forName(StringClass);
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
Intent i = new Intent(getApplicationContext(), Show_Subjects.class);
String Subject_number = String.valueOf(position+1);
i.putExtra("subject_number", Subject_number);
startActivity(i);
}
}
}
});
}
#Override
public void onResume() {
super.onResume();
adapter.notifyDataSetChanged();
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
switch (id) {
case R.id.action_settings:
Intent delIntent = new Intent(Search.this, Settings.class);
Search.this.startActivity(delIntent);
return true;
case R.id.action_favorites:
Intent delItemIntent = new Intent(Search.this, Favorites.class);
Search.this.startActivity(delItemIntent);
return true;
}
return id == R.id.action_settings || super.onOptionsItemSelected(item);
}
}
my string names are Subject_N , i want to send values of N to next activity(from item row number)
my language is persian ,also i have an other problem, search field only support english ! change language is Inactive

//outside the for loop
ArrayList<String> ArraySubject_number = new ArrayList<String>();
String Subject_number;
//initialize your arraylist inside the loop for each row
//use something like
//for each row
Subject_number = String.valueOf(position+1);
ArraySubject_number.add(Subject_number);
//outside for loop
Intent intent= new Intent(getApplicationContext(), Show_Subjects.class);
intent.putExtras("subject_number", ArraySubject_number);
then in your other activity use this code to access them
ArrayList<String> ArraySubject_number = (ArrayList<String>) getIntent().getSerializableExtra("subject_number");

multiple order entries in android application

I'm working on an order management system for android.
On the order page where the user submits an order, i want it to be able to allow the user to submit multiple orders, then take the user to a page where it displays all the orders made.
What method can i use to accomplish that?
This is the order activity page which is made up of 3 spinners and one textfield. This page takes the user to a ViewOrder page which displays what the user has selected. Instead of that i would like the user to submit multiple orders first, then see the display of all orders submitted. Any help is much appreciated.

// TODO Auto-generated method stub
}
});
}
}

Once try as follows take an List for multiple orders
ArrayList<String> orders=new ArrayList<String>();
as class variable in activity
then store a complete order as string with some special character as divider like
String msg1=sp1.getSelectedItem().toString();
String msg2=sp2.getSelectedItem().toString();
String msg3=sp3.getSelectedItem().toString();
String message = txtCrates.getText().toString();
orders.add(msg1+","+msg2+","+msg3+","+message);
then for intent add as follows
intent.putStringArrayListExtra("orders", orders);
Hope this will helps you.

Android - Selecting different spinner option doesn't update calculation in TextView, only working on 1st item in list

I have a simple spinner which has several number options. I want to just select a number and then it does some math to that number and outputs it in a text box. For some reason it's only doing math on the 1st entry in the list and if you change it doesn't update.
Any ideas?
package placeorder.com;
import java.util.Random;
import android.app.Activity;
import android.os.Bundle;
import android.widget.Spinner;
import android.widget.TextView;
public class Time extends Activity{
double totalhours, cost;
int price;
TextView total, orderid;
#Override
public void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.time);
Spinner spinhours = (Spinner) findViewById(R.id.sp_hours);
total = (TextView) findViewById(R.id.tv_total);
orderid = (TextView) findViewById(R.id.tv_orderid);
Random order = new Random();
int randomorder = order.nextInt(9999);
order.nextInt(9999);
orderid.setText("Order ID: "+randomorder);
price = 5;
String hours = spinhours.getSelectedItem().toString();
totalhours = Integer.parseInt(hours);
cost = totalhours * price;
total.setText("£" + cost);
}
}

You should add listener for spinner
spinner.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> arg0, View arg1,
int arg2, long arg3) {
String str = (String) arg0.getSelectedItem();
outputTextview.setText(str);
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});

ListView not updated after database is changed

I'm really frustrated because of bad programming style, and inexperience in Android. Sorry to tell you guys that.
How the app works:
This is a todo app for my job training. There are 6 columns.
3 of these contain information about the todo and the other 3 contain a view detail, edit, and remove screen.
When the user clicks remove for some reason even after setting a notifyDataChange, my screen is not updated and the deleted row it's still displayed.
Any ideas of what is going on here? I've tried many solutions for about 3 hours now
The code is posted here sorry if its a bit tedious.

}
The delete method:
public void delete(int position) {
theDatabase.beginTransaction();
try {
theDatabase
.delete(DATABASE_TABLE, KEY_ROWID + "=" + position, null);
theDatabase.setTransactionSuccessful();
} catch (SQLiteException e) {
// TODO: handle exception
e.printStackTrace();
} finally {
theDatabase.endTransaction();
theDatabase.close();
}
}

before notifyDataSetChanged you need to remove the entry from the List

Did you see any exception when deleting from database. and you also need to delete pos entry from global list before notifying.

How to get string from selected item of SimpleCursorAdapter?

I'm using an AutoCompleteTextView to suggest user some words from my sqlite db as they type the input string to search.
I try to make the suggestion look friendly by using simple_list_item_2, here's my code:

super.onCreate(savedInstanceState);
setContentView(R.layout.main);
auto = (AutoCompleteTextView)findViewById(R.id.auto);
auto.addTextChangedListener(this);

int[] displayViews = new int[] { android.R.id.text1,android.R.id.text2 };
simple = new SimpleCursorAdapter(this, android.R.layout.simple_list_item_2, cur,displayFields, displayViews);
auto.setAdapter(simple);
}
}
I got a problem with retrieving the string from clicked item. It is in:
auto.setOnItemClickListener(new OnItemClickListener(){
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
// TODO Auto-generated method stub
main = auto.getText().toString();
//Log.v("CURSOR",finish);
result.setText("");
auto.setText("");
}
});
I need both strings from word and meaning fields.
Any response would be great...

You need to use http://developer.android.com/reference/android/widget/CursorAdapter.html#getItem(int).
Cursor cursor = (Cursor) simple.getItem(position);
// retrieve the data from the cursor

This seems to be a problem with SimpleCursorAdapter on 2.1, on 2.2 the cursor is positioned on the requested item and you can retrieve the column data but in 2.1 the cursor position is 0 and cursor.move(itemIndex) and cursor.moveToFirst() both return false.
I plan to do a RYO database adapter.

Getting string from SimpleCurstor Adapter using cursor
#Override
public boolean onSuggestionClick(int position) {
//First get cursor from your Adapter,
Cursor cursor = (Cursor) mAdapter.getItem(position);
/* Then get string data from cursor's column, I am getting it from column 0 in this case. You can use your own column index. */
String s=cursor.getString(0);
//Then set the searchview or autotextview with that string
mSearchView.setQuery(s, true); //true will submit the query
}
