Android :: Trapping OnItemSelected Events From An Auto Complete List

Feb 6, 2010

I am trying to write an application with a list of items read in from a file. This item list and the fields that go with each item are fed into a DB. The item names are presented to the user as an auto- completing list. Once the list item is selected, I would like to get the value from the list and use it to query the database and display all the detail information.

The problem I am having is trapping the event using onItemSelectedListener and onItemSelected.

Below is what I am trying.

CODE:..............

This doesn't compile, but it has the fewest syntax errors.

How to get an OnItemSelectedListener to work? and how I grab the value selected?

Android :: Setup Contact List / Auto Complete Feature Not Showing All

Feb 5, 2010

I recently got the G1 and used my Gmail account online (via computer) to setup my contact list and then sync it to my G1. Now when I compose an SMS message, and begin typing the name of the person in my contact list, only some of the names that match will appear in the drop down auto-complete list but others that match don't show up at all. To compose SMS to them I have to use the Contacts>Scroll to contact>Select text to mobile method. Any ideas why some of the contacts do not show up in the auto-complete list when composing an SMS and typing in a partial name in the To field?

General :: Auto-complete On / Off And Websites

May 28, 2013

I type out websites on Whatsapp and in my browser on a regular basis, but with auto-complete I end up saving and typing words that I didn't intend to because of the format of a URL. I could turn auto-complete off, but I still need it when I'm doing regular texting.

Is there any keyboard with a button that can turn auto-complete on/off when pressed? Or perhaps a home screen shortcut that can do this?

I can't even make a custom shortcut to the language & keyboard, and doing it manually takes too long.

Samsung Fascinate :: Swype Auto Complete Feature

Oct 10, 2010

I have only had my fascinate for a couple of days but I already love swype. However, I am having a problem with the auto complete. Whenever I input an 'a' the first option on auto complete is ' asw@armysurpluswarehouse.com' which is apparently from one of my google contacts. Since the web address has a period in it I am unable to select the entire thing at once by double tapping so that I can tell swype to take the word out of the dictionary it uses.

Motorola Droid :: Temporary Auto-complete Disable?

Dec 11, 2009

When texting I enjoy the use of auto-complete using the glass keyboard. Except auto-complete wants to change short-hand "words" to real words of different meanings. My work-around is to open the physical keyboard and edit. Is there a way to disable predictive text for a single word? That way "GF" doesn't change to "Greg", for example.

Sometime I'll look into this auto-correct for the physical keyboard: You want predictive text wth physical keyboard here is how you do it. You are welcome - Droid Forum - Verizon Droid & the Motorola Droid Forum

Android :: Updating Media List When Thread Complete

Feb 22, 2009

I am developing an application on the Android Platform for my music service (axcid.org). Haven't spent a huge amount of time in Java but could use a bit of help with this code: http://pastebin.com/m5300a4e6

Bit of bad practice in there I know but I haven't spent a ton of time developing Java apps. Anyways the problem:
if (!this.listLoaded) { //holdup this needs it's own thread
//Url load and parse time. // Now we can start a thread for the search
Thread thread = new Thread(this); thread.start();

I need update media list to be called when:
public void run() { // search
String URL = this.getIntent().getExtras().getString("searchurl");
sm.LoadResults(URL+"?android=1"); listLoaded = true; }
is done. However calling it from the thread will crash Android. Did many google searches but found nothing. How can I call updateMediaList when the thread is complete? (from the UI thread)

Android :: Catching Selection Events For Custom List Items

Nov 3, 2010

I thought I knew how to catch list selection events in Android and then I regained consciousness. In my situation, I have a ListView that I populate with a custom view, all of the same class (let's call it the NewsChannel() class). NewsChannel consists of a LinearLayout of ImageViews and TextViews. When the list is displayed, the user may select a NewsChannel item in the list; I want to find out which list item was selected. Also, I registered an onClickListener to one of the TextViews and that works fine: when the text is clicked on, an activity is launched which is looking for the position of the NewsChannel item in the list. So, here's what my code looks like:

1. Registering the onClickListener in the ListActivity:
public class NewsListActivity extends ListActivity {...
public void onCreate(Bundle icicle) { super.onCreate(icicle);
setContentView(R.layout.news_list_format); ListView lv = getListView();
lv.setOnItemClickListener(new OnItemClickListener()
{ public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// When clicked, show a toast with the TextView text item_index = position;
Toast.makeText(getApplicationContext(), "item clicked = " + position,
Toast.LENGTH_SHORT).show(); }}); ...

2. The layout for the ListView associated with NewsListActivity:
<?xml version="1.0" encoding="UTF-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/ android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="fill_parent" android:background="@drawable/wpaper_tile" >
<ListView android:id="@id/android:list" android:layout_width="fill_parent"
android:layout_height="fill_parent" android:layout_alignParentTop="true"
android:dividerHeight="15dp" android:divider="@android:color/transparent"
android:cacheColorHint="@android:color/transparent" android:scrollbars="none" />

<FrameLayout android:layout_width="fill_parent" android:layout_height="55dp"
android:layout_centerHorizontal="true" android:layout_alignParentBottom="true"
android:background="#88000000"/>
<ImageView android:layout_width="fill_parent"
android:layout_height="wrap_content" android:layout_centerHorizontal="true"
android:layout_alignParentBottom="true" android:src="@drawable/phonetop_bg" /> </RelativeLayout>

3. The NewsChannel layout:
<?xml version="1.0" encoding="UTF-8"?> <RelativeLayout xmlns:
android="http://schemas.android.com/apk/res/ android"
android:layout_width="fill_parent" android:layout_height="wrap_content">
<include layout="@layout/news_heading_format"
android:id="@+id/news_heading_header"/>
<ImageView android:id="@+id/news_channel_image" android:layout_width="88dp"
android:layout_height="66dp" android:layout_alignParentLeft="true"
android:layout_below="@id/news_heading_header" android:padding="10dp" />

<TextView android:id="@+id/news_channel_text" android:lines="4"
android:inputType="textMultiLine" android:layout_toRightOf="@id/news_channel_image"
android:layout_below="@id/news_heading_header" android:layout_width="fill_parent"
android:layout_height="wrap_content"/> </RelativeLayout>

When I run the app, the ItemClickListener is never called. However, if NewsChannel were of a simpler type, say, a single ImageView or TextView embedded in the layout, the callback does get called. Any idea what I'm doing wrong? My whole goal is simply to let the activity launched by NewsChannel (not shown) to find out which instance of NewsChannel it was launched from.

Android :: How To Set Delay In OnItemSelected() Funtion

Nov 24, 2010

I am using a menu in my application Same as this post... I am using a gallery view for display my menu items

Text Gallery on Android?

Problem is that, i implement onItemSelected listener for gallery, so that when new item is selected data related to that topic loaded. But i also want to allow user to scroll the gallery fully. but each time when user move to next item onItemSelected() function called and it start loading data.

All i want to do is to put some delay in onItemSelected() function, so that if in between that delay user scroll next item than there is no need to load data of previous but for the current. Time may be 1 second. If user dose not go for next item in 1 second, that data of that item must be loaded.

I thought to start a thread,but each time for onItemSelected() there will be new thread...

I try this to.

Android : How To Cancel An OnItemSelected Upon Startup?

Aug 5, 2009

1) I have a Spinner with several options provided by an ArrayAdapter and have an onItemSelected listener on this Spinner. When selecting an item from the spinner, I want to display another view (list-view) but this method is unintentionally invoked upon initially displaying the view. The list-view is therefore displayed upon startup of the application. It is possible to add a spinner-on-item-select listener that won't fire upon initially displaying the view but only by the user selecting an item?

Android :: How To Keep OnItemSelected From Firing Off On A Newly Instantiated Spinner

Apr 1, 2010

I've thought of some less than elegant ways to solve this, but I know I must be missing something.

My onItemSelected fires off immediately without any interaction with the user, and this is undesired behavior. I wish for the UI to wait until the user selects something before it does anything.

I even tried setting up the listener in the onResume, hoping that would help, but it doesn't. How can I stop this from firing off before the user can touch the control?

Android :: Spinner Won't Respond To Clicks - Even Though OnItemSelected Is Called?

Jul 22, 2010

My Activity implements OnItemSelected listener for a spinner. It has the interesting problem of firing off the onItemSelected callback when the activity shows. So I used a flag hack to solve it (I hate it, but at this point I just want the app to work).

Strangely enough, even though the callback gets called right at activity start, my actual touch selections don't work. I can touch the list, open it, see the strings from the array adapter, and even touch it to make it dismiss - but the callback is never called.

My code:

CODE:...........

In onCreate():

CODE:..............

The callback:

CODE:................

The toast is shown right when the activity is shown, but when I select items in the spinner, the spinner dismisses and no toast is displayed again (not to mention the rest of the code in the callback fails to execute).

Android :: How To Catch Fire Of OnItemSelected Of A Spinner After The Interface Has Been Setup

I am having an Android view with a Spinner on it. I call a populateSpinner() method to add some default values to it.

I also have a onItemSelected() event which gets called before the view is completed to print.
I would like to run a code inside this block only when the user changes the selected items, not when I add or the form gets created.

General :: How To Disable Dropdown List Auto-opening In AutoCompleteTextView

Mar 19, 2012

In my android app I use AutoCompleteTextView and refresh items list for each 5 seconds. Refreshing is working, when I call notifyDataSetChanged(). But when I type here something and it'll give me the list of matching items and then I close it manually, when another thread is refreshing the list and calling notifyDataSetChanged() dropdown list is showing automatically (even if I closed it before). And it's really annoying, because if list is long it takes whole screen and after closing it'll appear in another 5 secounds. I tried dismissDropDown() just after calling notifyDataSetChanged(), but it doesn't have any effect. It looks like dropdown is showing with a little delay. It's also not good way to fix it, because if user hasn't closed the list it'll close after a refresh. Also tried to take focus away - still no effect.

So I need a method to: update my items list (via notifyDataSetChanged()) without automatically showing dropdown list, but if dropdown was already showed don't close it.
