Building an auto complete text view to hold email message contacts - android

I need to create an auto complete text view that will be used in a send email form, the auto complete text view will be loaded with the email contacts of the phone, The user can select from the auto complete drop down list any contact he wants, When he chooses another contact, the value of the auto complete is replaced by the new one, I want the new value to be added to the original one, any one knows what event should i use?

This example demonstrates how to create a class that handles the event given by the spinner when it's changed:
Spinner on value Change
You extend the OnItemSelectedListener class, override onItemSelected() and put your code in there to update the view with the new contact's details.
Then apply your listener to the spinner, perhaps in the onCreate() of your activity:
spinner.setOnItemSelectedListener(new MyOnItemSelectedListener());

Android filter ListView with users options

I am creating an app in which a user can set some preferences in a PreferencesActivity and then I got a fragment with a ListView which is supposed to be filtered according to what the user has chosen. I already got a Filter which is filtering the list with users text input but I'm not sure how to filter according to preferences made in the PreferencesActivity.
The data class representing a single list item looks something like this:
public class MyData
{
private ArrayList<SomeEnumType> enumListMember;
private String forRegularStringFilter;
...
}
public enum SomeEnumType
{
VAL1,
VAL2,
VAL3
}
What the user sees in the preferences is a MultiSelectListPreference with entries VAL1, VAL2, VAL3, and the user can select several of them. After the user finishes his selection, the list is suppose to show only the items which its enumListMember contains all the enum values the user has chosen. for example, the list of the class can contain VAL1 and VAL3 so if the user is choosing VAL3, the item is supposed to show. If he chooses VAL2, it's supposed to be filtered.
How and where do I make this kind of filtering? in the Adapter's getView? somewhere else?
What I eventually did was simply creating a new adapter with the correct values and replacing the old one every time a filtering was needed.

How to make user submit information in a particular order?

I'm trying to build a user input form in Android by displaying the following input views on an activity screen:
Spinner (Get a location from pre-filled options)
EditText (Get exact address)
Spinner (Get 2nd location from pre-filled options)
EditText (Get exact address)
Date
Time
Now, I want to allow the user to fill the above fields only in the particular order mentioned above, eg. user should not be able to see options in 2nd spinner unless she selects one from the 1st spinner, or user should not be able to fill EditText fields before selecting option from spinners...
How can we ensure this?

How to create an editable directory in Android

I want to create a new activity called "Custom Directory". That activity will have a heading called "Directory"
With the following list format:
Name Number
Name Number
Name Number
And at last a button called "Add new.." Where we can add more of such names/numbers.
Also on long pressing any item, a context menu will come called Edit/Delete.
How do I go about doing this? With file writing and stuff, to save the data to sd while the app is inactive?
Take one list view and edittext when you enter data into editext stored into "List"(Whatevere container you use i.e Arraylist.Array) and this "List" container set into adapter
Now give onlongcliklistener your listview item for delete and edit

ideal database field for calling data to

Hello people can someone help.
I have designed a dialog in which I would like to have a field box or some sort that when the dialog is called the TYPE & AMOUNT (link) box's will display the data from database on each item. So for this dialog I have made. The user will click drinks button on the activity before the dialog. And the data will fill theses field boxes once called.
My question is what can I use for this data box caller.
You can use TextView or EditText widget (depending on if you want user to just see or edit the data respectively) and you can pull data from SQLite Database.

How to filter listview data and add specific text on the top of the row in android listview.Can anyone help me?
I have a custom adapter and whenever i got response i am spiting it and storing data for the list in multiple arraylist because my list row has data like ipaddress,statustext,durationtext and no. of visit text value and one button invite.If any chat request come then invite button will be hide and Accept and deny button will appears and on clicking on accept a chat window open and accept button text change to join and deny button will be invisible.
I have to show chat request message remain at the top of the row until the user does not something.
If you store the date in a List you cann filter the new values and if the value chat you add it to the list with the index eg. list.add("text",0); and than you should rebuild the ListView with the list.
