Speed up Listview load and sort it

I have small Android app, but the Sqlite database is big, and the form loading is slow. How Can I speed up Listview load and sort it by name?
My code is here:
public void nameload(){
ArrayList<String> names = new ArrayList<String>();
db = openOrCreateDatabase(Adatbazis, MODE_PRIVATE, null);
Cursor Namecursor = db.rawQuery("select DISTINCT name from Table WHERE ztr='"+ztrcode+"'", null);
Namecursor.moveToFirst();
String name = "";
while (!Namecursor.isAfterLast()) {
name = "" + Namecursor.getString(Namecursor.getColumnIndex("name"));
names.add(name);
Namecursor.moveToNext();
}
//A tömb elemeinek betöltése a UI-ba
ArrayAdapter<String> adapter1 = new ArrayAdapter<String>(
this,
android.R.layout.simple_list_item_1,
names);
namelist.setAdapter(adapter1);
Namecursor.close();
}
Thank you for help me :)

Always remember Closing the cursor after setAdapter() may prevent the adapter from accessing the data which makes the loading slow.
So move your Namecursor.close(); after the loop, before ArrayAdapter<String> adapter1 = new ArrayAdapter<String>(..)

How to fetch data into a textview?

This is my code to fetch database values into the listview.
private void fetchData2() {
db = helper.getReadableDatabase();
Cursor c = db.query(DBhelper.TABLE2, null, null, null, null, null, null);
adapter = new SimpleCursorAdapter(
this,
R.layout.row2,
c,
new String[]{DBhelper.Amount},
new int[]{R.id.lbl});
list.setAdapter(adapter);
}
I just want to change this code to get the values into a textview,

You can do like this...
if(c.moveToFirst()){
String data = c.getString(c.getColumnIndex("Column's Index"));
yourTextView.setText(data);
}

After Binded Spinner , How to Do not select first item?

public void DatabaseConn(){
DataBaseHelper myDbHelper = new DataBaseHelper(this.getApplicationContext());
myDbHelper = new DataBaseHelper(this);
try {
myDbHelper.createDataBase();
} catch (IOException ioe) {
throw new Error("Unable to create database");
}
try {
myDbHelper.openDataBase();
}catch(SQLException sqle){
throw sqle;
}
SQLiteDatabase db = myDbHelper.getReadableDatabase();
//SQLiteDatabase db = SQLiteDatabase.openDatabase("/data/data/com.example.abc2/databases/DB_BusData", null, 0);
Cursor c = db.rawQuery("SELECT * FROM Tbl_Driver", null);
startManagingCursor(c);
//create an array to specify which fields we want to display
String[] from = new String[]{"Driver_Name"};
//create an array of the display item we want to bind our data to
int[] to = new int[]{android.R.id.text1};
//create simple cursor adapter
SimpleCursorAdapter adapter = new SimpleCursorAdapter(this, android.R.layout.simple_spinner_item, c, from, to );
adapter.setDropDownViewResource( android.R.layout.simple_spinner_dropdown_item );
//get reference to our spinner
Spinner s = (Spinner) findViewById( R.id.DriverSpin);
s.setAdapter(adapter);
db.close();
}
This is the code how i bind my Spinner with my DataBase,
But After Binded Spinner, will automatically selected first item,
i would like to let User select the Spinner by themself, how to do with this?

read this documentation page: http://developer.android.com/reference/android/widget/AbsSpinner.html

Just add a default selection after populating the spinner something like --select driver-- then do a check in your listener to not do anything when the spinner position is 0

SQLiteDatabase db = myDbHelper.getReadableDatabase();
//SQLiteDatabase db = SQLiteDatabase.openDatabase("/data/data/com.example.abc2/databases/DB_BusData", null, 0);
Cursor c = db.rawQuery("SELECT * FROM Tbl_Vehicle", null);
//=====Add Additional=====
MatrixCursor extras = new MatrixCursor(new String[] { "_id", "Plat_No" });
extras.addRow(new String[] { "-1","< Select Vehicle >" });
Cursor[] cursors = { extras, c };
c = new MergeCursor(cursors);
//===========================
Just Add the First Items as blank or i have added "< Select Vehicle >" as the first item

How to Fill a Spinner with Database Info

I have a spinner that I need to fill with information from a database, but the examples that i found don't work.
Here is my code:
public void consulta() {
AdminSQLiteOpenHelper admin =
new AdminSQLiteOpenHelper(this, "administracion", null, 1);
SQLiteDatabase bd=admin.getWritableDatabase();
Cursor c = bd.rawQuery("select name from category",null);
startManagingCursor(c);
// create an array to specify which fields we want to display
String[] from = new String[]{"name"};
// create an array of the display item we want to bind our data to
int[] to = new int[]{android.R.id.text1};
// create simple cursor adapter
SimpleCursorAdapter adapter =
new SimpleCursorAdapter(this, android.R.layout.simple_spinner_item, c, from, to );
adapter.setDropDownViewResource( android.R.layout.simple_spinner_dropdown_item );
// get reference to our spinner
spinner1.setAdapter(adapter);
bd.close();
}

This is how I do it:
db = SQLiteDatabase.openDatabase("/data/data/packagename/databases/mydata.db", null, SQLiteDatabase.OPEN_READONLY);
Cursor c_cat = db.rawQuery("select _id, column_desc from your_table", null);
startManagingCursor(c_cat);
spinner = (Spinner) findViewById(R.id.spinnername);
String[] from = new String[]{"column_desc"};
int[] to = new int[]{android.R.id.text1};
SimpleCursorAdapter mAdapter = new SimpleCursorAdapter(this, android.R.layout.simple_spinner_item, c_cat, from, to);
mAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(mAdapter);
db.close();
I did all that in my onCreate. I declared all my variables outside the method so that they are public to the whole class. One thing I made a mistake of in the past was closing the cursor after filling the spinner. The cursor must remain open if you want to see data in the spinner.
I hope this solves it for you.
EDIT: I noticed you are not querying for _id in your rawQuery. You must include that if you wish to populate the spinner. Analyze the code I provided.

Assuming you didn't leave any code out, you need to find/define spinner1, so that the framework knows where to put your info from the adapter.
private Spinner spinner1;
spinner1 = (Spinner) view.findViewById(R.id.yourspinnerid);
// rest of your code

How to set a contact's number in an auto complete textview in android?

I have a code from where I can get the contacts name in a auto complete text view, here is my code
autoContacts=(AutoCompleteTextView)findViewById(R.id.actvContacts);
Cursor emailCursor = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, null);
startManagingCursor(emailCursor);
autoContacts.setAdapter(new SimpleCursorAdapter(this, android.R.layout.simple_dropdown_item_1line, emailCursor, new String[] {Email.DATA1}, new int[] {android.R.id.text1}));
autoContacts.setThreshold(0);
but when I click in one of the name then it sets a text in that Autocomplete textview like this:
android.content.ContentResolver$CursorWrapperInner#44efc9c8
but here I want to set the specific phone number on that, how to fix this issue?

You need to use the setCursorToStringConverter
Sets the converter used to convert the filtering Cursor into a String.
http://developer.android.com/reference/android/widget/SimpleCursorAdapter.html
In your case you could do something like this:
String[] from = new String[] {
ContactsContract.Contacts.DISPLAY_NAME,
ContactsContract.CommonDataKinds.Phone.NUMBER
};
autoContacts=(AutoCompleteTextView)findViewById(R.id.autoCompleteTextView1);
Cursor emailCursor = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, null);
startManagingCursor(emailCursor);
SimpleCursorAdapter adapter =new SimpleCursorAdapter(this, android.R.layout.simple_dropdown_item_1line, emailCursor, from, new int[] {android.R.id.text1});
adapter.setCursorToStringConverter(new CursorToStringConverter() {
#Override
public CharSequence convertToString(Cursor cursor) {
final int columnIndex = cursor.getColumnIndexOrThrow(ContactsContract.CommonDataKinds.Phone.NUMBER);
final String str = cursor.getString(columnIndex);
return str;
}
});
autoContacts.setAdapter(adapter);
autoContacts.setThreshold(0);
