View 1 Replies View RelatedAndroid :: Select Item In List / But Modify It
Sep 24, 2010One thing driving me crazy in Android is if you start typing say in a search box (like in market, maps, etc.) and you see a choice that is almost what you want, you cannot select it and modify it.For example, I accidentally type pinboll in market.It finds nothing.I start to type pin again, there is pinboll. There seems to be no way to select that and be able to change the one letter. I have to retype the whole thing. Am I missing something?

Android :: Click In List View Item Changes Status Of Elements Inside Item?
Apr 9, 2010I don't know exactly how to explain this problem, but I'll try. I have a ListView with several items. Each item has inside a TextView and two ImageView. I want the ImageView change when I click on them, and I want to open a context menu when I press for a long time into the ListView item.For the ImageView, everything works properly. For the whole item, I can show the context menu after a long press, but my problem is that the ImageView changes as well when I am pressing the TextView, for example.I hope you understand my problem. I think that all the children of a view are affected by an event in the parent, but I am not sure.

View 2 Replies View RelatedAndroid :: Way To Extend An ArrayAdapter?
Apr 10, 2009I'm running into difficulties overriding an ArrayAdapter to be displayed in a ListActivity. The ArrayAdapter is filled asynchronously. What I'm trying to do is add a special "sentinel" object that sits at the beginning of the list to show the progress of the computation. Ultimately this may be a progress bar, but right now I am just using a TextView as a placeholder. The problem is that the sentinel seems to get inserted multiple times into the list - not just once at the beginning. It *seems* to be appearing once per "page" of list data (so if 8 list items fit on the screen, my sentinel appears as the 1st, then 9th, then the 17th, etc..), but that interpretation may not be accurate. While maybe not how ArrayAdapters were intended to be extended, I thought something like this should work by simply overriding getView() to show my custom TextView for index.

Android :: Possible Databinding When Using A ArrayAdapter?
Apr 19, 2010I need some simple databinding for a Spinner. I want to display 2 items for each dropdownitem.
So when the user clicks the spinner I get a list like code...
I understand this can be done when using a Cursor, according to the databinding info on android dev. Like code...
However, I don't get my data from a database, so I don't use a cursor, I use a ArrayAdapter. Unfortunately it looks like there is no support for databinding with this adapter.
Is there a way to do this?
Android :: Why Can't Add - Remove Items From ArrayAdapter
Aug 13, 2010I am using an ArrayAdapter<CharSequence> to populate the items to list in a android.widget.Spinner. That works all fine. But now I want to keep the list of items dynamic, i.e. I want to be able to add/remove items from the selection list at runtime. However, when I call adapter.add(item) or adapter.remove(item) I always get a UnsupportedOperationException, even though the Javadocs of the ArrayAdapter class describe these two methods as to be usable for exactly that intended purpose.

Should I just use setId upon creation of the view and just throw that id into the array adapter, or is there a way to create one without using resource id's?

View 11 Replies View RelatedAndroid :: Find Item In List Without Filtering List But Just Scrolling To That Item
Oct 17, 2010Trying to implement simple dictionary. I want to make it so while the user is typing in the EditText box the list to scroll automatically to the best match. I don't want it to filter the list. For example if the user types "s" in the EditText I want the first word that s/he sees under the EditText box to be the first word in the dictionary that starts with "s." But the user should still be able to slide up and down and to be able to see the entire list of words. It is basically like a go to functionality. I used ArrayList to store my list of words. The data is in res/raw/data.xml file. Here is my onCreate method
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
wordListView = (ListView)findViewById(R.id.wordList);
myEditText = (EditText)findViewById(R.id.myEditText);
words = new ArrayList<Word>();
arrAdap = new ArrayAdapter<Word>(this, android.R.layout.simple_list_item_1, words);
wordListView.setAdapter(arrAdap); try {
InputStream inSource = getResources().openRawResource(R.raw.data);
DocumentBuilder builder = DocumentBuilderFactory.newInstance().newDocumentBuilder();
Document doc = builder.parse(inSource, null);
NodeList wordsList = doc.getElementsByTagName("eng-bg");
int length = wordsList.getLength();
for(int i = 0; i<length; i++) {
Element entry = (Element)wordsList.item(i);
Element eng = (Element)entry.getElementsByTagName("english").item(0);
Element bul = (Element)entry.getElementsByTagName("bulgarian").item(0);
Element id = (Element)entry.getElementsByTagName("ID").item(0);
String english = eng.getFirstChild().getNodeValue();
String bulgarian = bul.getFirstChild().getNodeValue();
int wordId = Integer.parseInt(id.getFirstChild().getNodeValue());
Word word = new Word(bulgarian, english, wordId);
addNewWord(word);

Android :: Notifying An ArrayAdapter Of Changes When Closing A PreferenceActivity
Dec 12, 2009I have a ListView that has some minor visual preferences that are set in a PreferenceScreen. These preferences are simple booleans to show or not to show some specific TextViews on each item in my ListView.
Anyhow, when these preferences are changed, I need to notify my ArrayAdapter that the data has changed in order to get the list redrawn. However, doing this via an OnSharedPreferenceChangeListener wouldn't really be optimal because there are several preferences that you can change, that would cause an unnecessary amount of updates to the ArrayAdapter.
So, to the question: How can I identify when my ListActivity has occurred on the screen after closing my PreferenceActivity, which I then could use to check for changes in the preferences, and only then notify the ArrayAdapter.
The ArrayAdapter being an inner class of my ListActivity, which is set as a ListAdapter.
Android :: Override Filter In Droid's ArrayAdapter?
Apr 19, 2010I have an ArrayAdapter wrapped around an ArrayList of custom objects. I'd like to write a custom filter for that adapter so that when I call getListAdapter().getFilter().filter("abc") the list will get filtered by an arbitrary transformation of "abc".
I thought I would just try to override ArrayAdapter.getFilter(), but that requires I re-implement the private ArrayAdapter.ArrayFilter which requires access to a bunch of ArrayAdapter's private instances.
What's the simplest way to do this?

Is it a problem to have a reference to a LayoutInflater object, since it must be using the context object somehow? Is there a better design pattern for what I'm trying to do here? (Use the context only to initially inflate the XML; from then on just use the View that's passed in to getView)
