Android :: Setting Selection To Last Item Also Loads First One
Jun 12, 2010
I'm developing application that shows thumbnails of images in gridview widget. I load HTML with image names, and set ImageAdapter. That image adapter loads single image (from internet or SD card) in AsyncTask with selected image position. After I initially download HTML with image names, and parse them to array, I set selection of GridView to index of last image. But, what happens is this : first image that gets downloaded is image with index zero. That gives me a lot of trouble because I'm using convert views and AsyncTasks, so sometimes I end up with wrong picture at first column in last row (sometimes picture with index 0 gets in there), depending on which AsyncTask gets executed first. Even stranger, I end up with around 10 calls to getView for image with index 0.Does anyone have idea how to switch GridViews position to last image, and not have image with index 0 loading?

I have an activity with a ListView check list and a spinner that controls the sort order of the items in that check list. One of the sort options is to move the checked items to the beginning of the list. I would like to allow users to check some items in the list, select the 'sort by checks' option, check some more items in the list, and select the 'sort by checks' option again. However, I don't see how to detect that second selection of the spinner's 'sort by checks' option.
I've tried using setOnItemSelectedListener, but it doesn't call the onItemSelected handler unless a different item is selected. And I've tried using setOnItemClickListener, but it seems that listener cannot be used with a spinner according to following run-time exception from logcat:
- - - D/AndroidRuntime( 987): Shutting down VM W/dalvikvm( 987): threadid=3: thread exiting with uncaught exception (group=0x4000fe70) E/AndroidRuntime( 987): Uncaught handler: thread main exiting due to uncaught exception E/AndroidRuntime( 987): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.test.spinner/com.test.spinner.check_list}: java.lang.RuntimeException: setOnItemClickListener cannot be used with a spinner. E/AndroidRuntime( 987): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java: 2268) - - -
Any tips on how to detect the selection of an already selected item in a spinner?

With spinner, I am able to create a dropdownlist menu. (As seen from the code below)
Quote:
// Set up the action bar.
final ActionBar actionBar = getActionBar();
actionBar.setDisplayShowTitleEnabled(false);
actionBar.setNavigationMode(ActionBar.NAVIGATION_M ODE_LIST);
[Code]...
However, how should i make it draw a XML upon selection of the item in the dropdownlist's array? Or should i just change everything to popup menu and onclicklistner instead of spinner.

when I click on one item in the ListView that item's background changes to light gray, but when I continue to scroll through the list every 4th item has the background changed to light gray even though those other items have not been clicked. How do I make only the item I clicked be effected by the click?
ListView lv = (ListView) findViewById(R.id.resultsList);
lv.setAdapter(new ArrayAdapter(this, R.layout.resultitem, (String[])labelList.toArray(new String[labelList.size()])));
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView parent, View view, int position, long id) {
TextView tv = (TextView)view.findViewById(R.id.result);
tv.setBackgroundColor(Color.LTGRAY);
tv.setTextColor(Color.BLACK);

I'm trying to use Spinner as a button with selection pop-up. Basically I want an icon and when user clicks it - the popup list is displayed and user can make a selection. The Spinner happily accepts icon image as drawable background. Unfortunately when I select a value the text overlays the background. Is it possible to set selection text color as a transparent? Or maybe there's a better way?

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.

Same problem that I've read on other posts. I don't want the soft keyboard to pop up when the Activity loads. The above code snippet works, however my View no longer scrolls up so that the User can still see the EditText.It scrolls without this line of code. Any ideas?

My wife has just got rid of her faulty X10 and moved to the X10 mini pro.
She's very frustrated as apps are just not showing up in the market. She used Bloo all the time along with AG Newspapers UK and Flood-it (game), these were 3 of the most used apps she had but when she searches the market for them it says they are not there! I have managed to get hold of the latest Bloo beta apk and installed that and it works fine.
Any ideas why these apps do not show up? the mini pro is 320x240 so it's not a resolution problem (same res as my old G1), the apps show up on my Desire (same phone network etc) the phone was unbranded/unlocked from Expansys

Pdanet worked up to where I was getting the warning that the trial was about to expire. I purchased the full version now I only get a strange partial connect that only loads half pages of what I'm trying to view or get pages that are timing out. Any suggestions on if it is a setting that somehow got changed or something else.

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);
} 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
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
// TODO Auto-generated method stub

Ok so I accidentally imported my sim card contacts into my phone twice. Now while I have hidden the sim card contacts so everything looks ok on the people screen, if i go into a contact and look at what it is linked to there is 3 versions of the contact all on the phone and all just with the number. Is there an easy way to sort this out? or should I just delete all my phone contacts and import from sim again?

I am loading a webpage using WebView.. my code looks like this..
Code:
public void open() {
myWebViewV = new WebView(this);
setContentView(myWebViewV);
myWebViewV.setWebViewClient(new WebViewClient() {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url){
view.loadUrl(url);
return true;
} });
myWebViewV.loadUrl("http://www.mywebsite.org");
}
what this simple code does is load the website that I want to view.. fine..
But this site also has things like "Reply", "Register", "Login" and etc..
I'm trying to change it so that the user has to click the buttons that I create for him/her that will do basically the same thing.

any way to get better video when you go to the site. Im not talking about the flash. You dont need flash for this video. It is the actual player that is crappy when it loads up. Had moto droid looked perfect but not with the incredible. They have a different video player that plays this crappy. view mobile view of espn and you will see what i mean when you click on the video link.

It seems after the device has been running for a day or two, the Internet browser will cease to fully load web pages. The load bar will get to some point and stop and the page never fully loads. No other web based apps are affected. At first I would restart the device and that, of course, would fix it. Lately I ended up just force stopping the browser and that fixed it as well.
