I got a ListView item that contains a button inside. Currently the long press of a ListView item does not get processed. I thought that by setting the Button.setLongClickable(false) would allow the long press to be passed along to the ListView item and it's not happening.

I 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 RelatedI 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.
Does anyone how I go about detecting when a user presses on a bitmap which is inside a canvas?

Trying 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);

e.printStackTrace();
} catch (SAXException e) {

} catch (IOException e) {

}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());

I have a question regarding a feature that just seemed to disappear from Handcent SMS.
Before, when I composed a message in the app or using quick compose (long press search button), there would be a drop down list of possible choices when I began typing in the "To:" field. For example, if I typed "k", it would show names beginning with "k". But now the feature is gone and it really sucks when I want to compose a text.
Does anyone else have this issue? Is it Handcent's problem or a software problem (v2.1 bug?), and does anyone know how to fix it?
a hardware bug on my Samsung Galaxy S Plus.I'm writing this in the general forums since it doesnt seem to be a bug specific to the phone (no reports anywhere online) and the question itself is therefore not device specific.So i have a hardware home button on the phone which sometimes registers two clicks instead of one.On a 1sec press this would mean the following events:
- button down event
1sec pause
- button up event
- button down event
- button up event
So since this doesn't occur regularly and i want to somehow log presses of the home button and i dont know any way to do that in android.It doesn't need to run in the background but could be for example be opened specifically to test the button.
I've been a couple of days trying to solve this thing but I can'f figure it out.The problem is, simple activity, with simple layout, ScrollView -> LinearLayout -> and a lot of buttons inside the layout (within the scroll content). Everything works just fine but one tricky thing. When I click a button let's say at the top of the scroll content and inmediatelly I scroll down to the bottom of the content and I click other button there, nothing happens until I click a second time and all come to normal again.This can be reproduced anytime and it's code independent (i've tried more than 20 scenarios). I've not much experience in android yet but looks like the scroll listener stops the onclick listener or something like that.

What is the best method for achieving this? I dont think that an OnClickListener works like that, and I have seen examples for doing this with an OnTouch event. However, I do not know how to set up button presses with an OnTouch event.

View 1 Replies View RelatedI am creating an Android service which constantly runs in the background. I'd like to be able to intercept calls to the power button to:
a) prevent the screen coming on
b) handle the power button press in a different manner.This is to enable the user to have a very simple interface to my application and prevent wasting battery powering up the screen when it is not required.
I will probably need an alternative mechanism to actually bring the screen back up (such as an extended key press or similar), but this only becomes relevant if what I'm after is possible.
First of all, maybe i went about this the wrong way in the first place. Situation is, i have a listview that when an item is clicked, it creates an intent and calls startActivityForResult() to another activity, to be able to edit the entries in the row. and that other activity after editing the required values, returns back to the calling activity, when the user clicks on a save button. The activity then uses the row Id to update the item.My problem now is that, if the user presses the BACK button instead, the application crashes. i have been looking around and see solutions like using Shared Preferences or onSavedInstanceState(), but i don't know where exactly i should be putting the code?

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 4 Replies View RelatedI'm trying to create a multiple selection list where the selection is represented graphically rather than with checkboxes.My list has checkboxes, but I want them to serve a different purpose. I'm using a cursor to hold my data and created a custom view binder for the SimpleCursorAdapter. I did this for the checkboxes and general flexibility.So far I haven't even been able to show one line as being selected. I've enabled multiple selection on the list and denied the children of the list item focusability. I've tried manually changing background color with the position fed in through the list item click listener. But the wrong items get changed and they don't even change to the right color. I've enabled touch focusability with no improvement either.Ideally, I'd like the trackball highlight focus bar to appear in multiple places. But I don't think this is possible unless you use the drawable directly. But I don't know how to find or apply it. My next idea was to have a slim view bar that changes color. But I had the same problem with the wrong item being selected so I never finished trying to guess the index position to see if this would work. My most recent idea is to completely swap out the view for another one if it's selected. But I have no idea how to do this either. I'm thinking of using an array list to store the _id s of the items that need a different view to get around the wierd selection problem. I'm also thinking of passing in the ID field as my from and the selection view as the to for my adapter. Then I'd intercept it with my binder and change the view accordingly. But once again, I'm not sure how to do this successfuly.
View 7 Replies View RelatedI use tabs in my Android application and one of my tabs contains a listview. I'm noticing some weird behavior when I override isEnabled in my list's adapter and then try to use the D-pad to move up and down through the list and to my tabs.If the 0th item of the list is enabled, then everything works as expected - I can move down through the list, and then up again and once I reach the top of the list, pressing up moves focus to my tab.However, if the 0th item is DISABLED (isEnabled in my adapter returns false), then when I press up while position 1 is focused, the focus gets stuck. It doesn't move up to the tab as I would have expected and instead stays on position 1 of the list.

All I have so far is creation of a Process object using Runtime.exec("su"). Then I get output stream from it and write "ls" command. And here goes the question. How to read the output of the "ls"? Getting the input stream from the process gives me stdout of the "su" which is useless.

View 2 Replies View RelatedI am implementing a music player application in Android. My play list selection screen is implemented as a tab selector widget which contains a ListActivity inside each of the tabs: Artist, Albums, Songs.
I want to update the ListView in each of the ListActivity when I delete an item from any of the lists.
i.e. When I long press an item in the Artists list a context menu is drawn with "Delete Artist"
And it should delete all the songs from this artist in the Songs ListView, delete all the albums by this artist in the Albums ListView, and finally delete the entry for the artist in the Artist ListView.
Each of the ListActivity has its own fillData() method, which updates the ListView when the button in the context menu is pressed.
How can I call the fillData() method of the Albums ListActivity after I update the ListView inside of the Artists ListActivity?

View 2 Replies View RelatedI have a list (ListView) which displays news items. They contain a image, title and some text. The image is loaded in a separate thread (with a queue and all) and when the image is downloaded, I now call notifyDataSetChanged() on the list adapter to update the image. This works, but getView() is getting called way to often now, since notifyDataSetChanged() calls getView() for all visible items. I want to update just the single item in the list. How would I do this?Problems I have with my current approch is that the list is slow and I have a fadein animation on the image which happens every time a single new image in the list is loaded.
