Jan 22, 2009I have a list using a customized BaseAdapter. When one element of the list is hit during a long time, a contextual menu appears. I want to use this one to delete or edit the selected item but I don't know how to get id or anything else that could help me.
I tried getListView.getSelectedItem() thinking that it will give me the object returned by the method getItem(int position) inherited in my customized BaseAdapter. I got null. When I tried getSelectedItemId(), I got -1.
Does someone have a solution?

Android :: Way To Present List To User Where Each Item On List Starts An Activity When Selected
Nov 4, 2010I am on my first Android application and I am on a timeline so details and examples will be useful since my knowledge is still minimal. I want my first screen to present the user with a list of activities to choose from. In my situation it is a recipe app where the user first chooses the type of food, such as, Beef, Chicken, or Pork. I want the application to launch an activity depending on the list item that the user clicked on. I am not sure if I should use a list view, a text view, a scroll view, a list activity, an activity group...
View 1 Replies View RelatedAndroid :: Orientation Change Crash In Tab Activity With List Activity
Jan 21, 2010When views with different type have same id and screen orientation changes,
either java.lang.ClassCastException: android.view.AbsSavedState$1 or java.lang.IllegalArgumentException: Wrong state class -- expecting View State will occur. (depends on the view's order)
Because View.dispatchRestoreInstanceState() checks id only.
You may wonder why anyone would make views with different type to have same id.
But it can happen when you use tab activity.
Imagine you have tab activity with two children activity.
Tab1 is ListActivity and Tab2 is ExpandableListActivity.
Both activity have id of "@android:id/list" but the type of view is different.
This means we cannot use ListActivity & ExpandableListActivit at the same in one tab activity.
Android :: Can Update A List View In One Activity While Im In Another Activity
Oct 4, 2010I currently have a tab layout with 2 tabs, one tab with a list view and one with the option make strings so I can add them in the list view. Both tabs have their own activity because this made the code much more structured, and I dont have to repeat my self later.
Lets say im in the tab that offer me to create an string, and i press the update list button, how do I update the list view without startActivity()? If i use startActivity(), it starts List.java, and instead of displaying the list in the list view tab, it takes full screen, which defies the purpose of the tab view. In other words, the startActivity() steals the focus from the tab view of the list, and sends it fulscreen.
I want to update the activity in my list view tab, without starting a new activity that goes to fullscreen, and doesnt update the one in the tab.
Android :: 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);
} catch (ParserConfigurationException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SAXException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}wordListView.setOnItemClickListener(new OnItemClickListener(){
public void onItemClick(AdapterView<?> parent, View view, int pos, long id) {
selectedWord = words.get(pos);
showDialog(TRANS_DIALOG);
myEditText.setText(selectedWord.getEnglish());
myEditText.addTextChangedListener(new TextWatcher(){
public void onTextChanged(CharSequence s, int start, int before, int count) {
@Override
public void afterTextChanged(Editable s) {
// TODO Auto-generated method stub
@Override

Android :: Contacts List IOS - Not Able To Find Anything
Oct 29, 2010So I've searched "Contacts list iphone" and what not but wasn't able to find anything. And I might get crucified for this but The one thing that the iphone did that I really liked was how you can easily scroll down to the contact you want by tapping the letter you want to scroll down to on the right hand side of the contact list. I have a Droid X and I LOATHE the way it works (I have to scroll first, then move the scrollbug down to where I want it). Is there an app that will show the contact list a la iOS where you have the letters on the righthand side and you just tap on the letter you want to scroll down to?

Android :: Design Clarification In Android List Activity Vs Activity
Mar 25, 2010I have a simple question. I am trying to design a simple Android app, which based on keywords searches something and shows a listing view of results. Currently it merely searches SMSes in the cellphone.Here are some of the things I am faced with: I have a simple first page with a textbox and a submit button. It's rendered by "Activity" inherited class call SMS Finder.once I have the results present with me, I want them to be binded to a list view. Showing preview text to limited characters, say 20 chars. Clicking on the same should "ideally" open the inbox (or outbox or whatever) and open the SMS, however that meant I cannot come back to my app easily. So I would rather open the whole SMS in my own app. So clicking on the app should open the SMS in a new screen with complete message, sender info etc. Few questions here, For generic Android phone apps, what are the best practices to make UI as compliant to as many phones? Like what kind of views should I use?

View 3 Replies View RelatedAndroid :: Display Images On Demand Inside A Listview / Find Out List Item Is On Screen?
Oct 31, 2010I am building a android aplication which will be consuming a json file from the internet. This json file contains a list of news from a particular website. Each json object contains information such like title, summary, descripition and web links for the news thumbnail and the original image.
I will be displaying in a listview three information: the news thumbnail, the title and the summary. Here resides my problem. I dont want to load all thumbnails from the internet if they wont be displayed. What I am trying to say is that why download a thumbnail from the 30th news if the user wont scroll down the image. So, i will, initially only download the thumnails from those news that are being displayed in the screen and when the user scrolls down to see more news, as soon as the list item appers to the screen i want to download the image and then display.
Is there a way to achieve this? Is it possible to find out if the list item is on the screen? I have been searching all over the internet for a solution for this but i am running out of ideas.
Android :: Way To Find Out Current Running Activity From A Service?
Aug 4, 2009I have been looking for this for a while but I can't find any way of doing it. A contrived example would be a service that simply displays the name of the current running activity as an Ongoing Notification. For instance, when the user is reading a particular email, the name of the activity (hopefully the email title!) would appear in the notifications window and when the user switches to read a text message, the notification would change to show the name of the new activity. Is there a way to do this in Android?
View 2 Replies View RelatedAndroid :: How To Find Service Running When Activity Resumes?
Dec 9, 2009I've created my first service, and it's all gone fine, except when the main activity is stopped. What I want is for a user action (button press etc) to start the service, which it does. Then I want the user, some time later, to press another button to stop the service. Which it does. But if the main activity loses focus (i.e. I go to the home screen) when I return to the activity it has no knowledge of the service anymore - even though the service is still running. When the activity resumes, how do I find out a) if the service is running, and if so b) re-bind to it, so that I can then stop it and collect the data I'm after.

View 1 Replies View RelatedAndroid :: Preloading List Activity ?
Nov 20, 2010I have a realtively complicated listview in my application, with data fetched from the internet and so on. What is the best practice to do to preload as much as possible of the ListView, such that it appears immediately on the screen?
For example, the standard SMS/MMS app of android shows a white screen with a spinning loader and "Loading..." before a conversation is shown. I can't really find this in the Android source code, but I guess this is an extra loading Activity doing some caching and handing over to the conversation Activity using finish(), so that no screen change animation is shown.
How can I preload or cache ListView items? Is it even possible to do that?
