Android :: How To Disable Autocomplete On AutoCompleteTextView
Dec 5, 2009
So this is a response to another thread, that I never got a reaction on. Hopefully someone can give a hand. I have a AutoCompleteTextView with a CursorAdapter with data. I need to be able to set a text in the AutoCompleteTextView programmatically without the autocomplete mechanism kicking in. If I use *setText *on the AutoCompleteTextView it will start the autocomplete. I tried calling *dismissDropDown() after setText, but this dosnt work because the drop down is not shown yet.
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.
I am trying to connect a AutoCompleteTextView with a SimpleCursorAdapter, which narrows down the selection of a list of words, when the user starts typing.
Following some other posts here, I've come up with the following code, but it doesn't work. I defined a FilterQueryProvider runQuery() method for the SimpleCursor Adapter, but when I use the debugger in the code, the response from the ContentResolver.query((0 method call is null.
I think the problem is that there is no relationship between the CONTENT_URI and the SQL database, but I can't be sure.
I have an application that involves reading a text dictionary file with about 7000 entries, and allowing the user to choose one of these. My first approach was to allow the user to select one of these by using a AutoCompleteTextView together with ArrayAdapter<String>. This works, but is very slow (~10 seconds to update the word list each time the user enters a character to narrow down the choice).
I was wondering how to rework it so that I could use a database using a SimpleCursorAdapter instead. In other words, to hope that a SQL database could provide a more efficient ordering and access for the elements. Is this the best way to do it? I've also seen several references to SQLiteDatabase, but don't know which one to use.
I found this code fragmant consisting of an extended SimpleAdapter. http://sacoskun.blogspot.com/2008/08...leadapter.html<http://sacoskun.blogspot.com/2008/08/autocompletetextview-with-simple...>
Unfortunately, this is not a complete worked out example. Could someone forward me a more complete example? I've found lots of code fragments, but no code that shows how to initialise the SimpleCursorAdapter contents, or how it works together with the AutoCompleteTextView.
Is it possible to have an EditTextPreference with AutoComplete attached to it?I know ho to attach one to an element with an id, but am having trouble figure out how to attach the ArrayAdapter to the preference field.This is wrong, but it's as close as I can get.
I can't seem to get AutoCompleteTextView to work with Theme.Light.The problem is the autocomplete popup draws the suggestions text in white on a white background. You can only see what the suggestions are after they are selected, because then the white text is drawn over top of the selector background.It works fine with the default theme but not with Theme.Light.I tried setting the android:textColor attribute.That only set the color for the AutoCompeleteTextView input box, not for the suggestion's popup.Right now the only way to get my app to work properly is to use the default theme.Does anyone else have the same issue or know of a way to programically set the suggestion's popup text color or background?
I've posted this in a couple of places without any help so hopefully this group has some helpful people :) I have an AutoCompleteTextView which I want to populate with artist names based on what the user types.The problem is that I have a thread for retrieving the names from a web service, but when I try and update the ArrayAdapter with a Handler on the UI thread (which is called from the web service thread), nothing gets updated on screen. When I type another letter though, then the previous results from web service are displayed in the autocompletetextview rather than the latest.
I have an AutoCompleteTextView working with a ContentProvider that correctly pulls known information from a database when the user is typing and presents it. However, I would also like to support the automatic hints/word choice list you get when using apps like the Messaging app. I haven't figured out how to get that thin bar of word choices to appear. Can some one clue me in on how to use that in combination with my existing ContentProvider?
Has anyone noticed that AutoCompleteTextView doesn't pass the focus to the next field when you tap on "NEXT" button on soft keyboard? And it's all happening on Android 1.6. v1.5 works flawlessly! Is there any known solution for this?
Is it possible to get Autocomplete or Something when i work with the eclipse form editor?I write a color in the strings.xml and then i want to select it by the propertys for the text color, but there is no autocomplete or something equal
I'm porting an app of mine to work better with API 1.5, and I'm having problems with the layout files where I'm using an AutoCompleteTextView (and, naturally, MultiAutoCompleteTextView). Whenever I have them present in a layout, the graphical representation of the layout disappears, and "NullPointerException: null" replaces it. Is there any way I can view a widget such as this in the Eclipse editor? It definitely worked in the 1.1 SDK, otherwise I wouldn't have used them.
I have a dialog window that covers 1/3 of the entire screen height and is displayed on top of my activity. The dialog holds two AutoCompleteTextView fields.
The problem I'm facing is that when the user starts typing something into the AutoCompleteTextView, the list with all suggestions only shows up to the bottom end of the dialog, but doesn't go beyond that even the list is longer. It looks like it's cut off. (screenshot left)
Only after I long-press an item from the suggestion list, the list will be shown in full length. (screenshot right)
Screenhot is at: http://img704.imageshack.us/i/dialogdropdown.png/
How to fix this behaviour so that the list shows in full length right from the beginning, when the user starts typing something?
Code-wise there's nothing special, all I do is:
One workaround idea is to somehow dispatch a motion event to simulate a touch (but then not selecting though) one of the list items. Any concrete idea in code for a solution.
i have done the blocking of the drop down list with dismissDropDown() but wen ever i do a settext on the autocompletetextview, the list drops down with the matched texts.i dont want that. i have set the input type of the autocompletetextview to TYPE_NULL, but still no result.plz tell me a way to block the drop down. i am controllin the drop down with a button thats properly working its only that wen i do a settext on it, the list drops down. how can i stop this.
I extend AutoCompleteTextView and override preformFiltering function in order to get results from database.I'm getting the results but then nothing is shown. And getView in custom adapter is never called.The strange thing that If I preload items (inside init() function) I can see them...May by anyone can point me to the right solution?
I'm using an autocomplete box, with suggestions provided by a SimpleQueryAdapter.Not sure if relevant, but only difference I see is that, both in the adapter constructor, as well as in runQuery(), I use a cursor returned by SQLiteDatabase#query obtained via an SQLiteOpenHelper instance.Should I be using on these cursors or not?If I don't use managed cursors, then I get "leak found" warnings ("database was created [sic] but never closed").
I'm having problem with creating AutocompleteTextView in custom dialog. In every example i saw, the autocomplete feature is only in the classes that extends activity.I need to have autocomplete in custom dialog that I created.
I just got my first Android phone (N1), and like it so far.There are a few things that drive me up the wall, though.One of them is the 'autocomplete' (not sure what it's called): where Android suggests words as you type a text message. Great when I'm typing English, not so great when using other languages.Can this be turned off?
Can someone point me to right direction, how to create an adapter for AutoCompleteTextView, which would be getting data from SQLite DB, using data, which user entered into the text field? I want to use the user-entered data to filter suggestions for autocompletion.I imagine that adapter should always take user-entered data as soon as changes appears and use it for fetching suggestions on-the-fly. Is that possible? So far I've seen many tutorials for autocompletion where static String arrays were used, but never seen them build dynamically.Is it possible to do it automatically or I need always fetch String array myself and pass as ArrayList to adapter on every AutoCompleteTextView change?
In my activity, I have an AutoCompleteTextView that gets its contents from my custom adapter. I created my adapter by following this example.The adapter works so far, but I am getting so many errors on leaks and cursors that are not finalized.My question is: how do I close the db in runQueryOnBackgroundThread?
I am using AutoCompleteTextView , when user clicks on it, I want to show suggestions even if it has no text - but setThreshold(0) works exactly the same as setThreshold(1) - so the user has to enter at least 1 character to show the suggestions.
I am facing the following problem: I have a big list of street names(~2000 entries), which is stored as a variable. I have an AutoCompleteTextView which should complete the names. The process takes really long time(approx. 2 - 3 seconds) to complete the suggestion. Is there any way to speed this up? I am pasting my code, if this is necessary:The getStreetsData() method simply returns the static list of the names.
Is this possible? Lets say I have an ACTV that shows you a list of contacts. If I place a T in the ACTV then it may generate a result of 10 contacts. In landscape mode (physical keyboard not open but phone turned sideways), the dropdown list gets covered by the onscreen keyboard. This will generate completion hints at the top of the keyboard. But these hints do not cover all of the data behind the ACTV. There is no way for the user to scroll through the entire list to see all of the data.
There should be someway to force the ACTV to scroll as I move through the onscreen completion hints. This would be an acceptable replacement of the ACTV list. There does not seem to be any such association.
Also, there does not seem to be any public association between the completion hints and your ACTV adapter. Currently, the only way that I know of matching a view(custom and holds data such as phone #, etc) referenced by my ACTV adapter is to do a match on the text placed in the ACTV when selected from the completion hint. I am posting here as the http://groups.google.com/group/android-developers/browse_frm/thread/5... thread appears to be dead.
I cannot seem to dictate the behavior of the onClick function.When a suggestion is clicked, it fires off the intent immediately. Is there a way for it to instead of firing off the intent immediately,simply copy and paste the suggestion as part of the search string?Eg. when typing in J,o,h the suggestion "John" comes up. When I click "John" can it copy that text into the search bar instead of immediately processing the search with John?I'm assuming theres a simple configuration which I cant seem to find.I dont want to go extensively into catching the fired of intent and re-processing etc
I am trying to implement a dynamic auto complete widget in android.I am done with the major functionalities and the auto completion implemented is for youtube video search.When I start typing a letter or two, the auto-completion is not working. But when I type three letters or more it works prefect.It also works when I type two letters and hit a backspace.I do not know what is wrong with the code.
