I need to get an item's position in spinner knowing it's ID. I've tried to do it with Spinner and SpinnerAdapter classes but there are no corresponding methods there.

I have a update view, where I need to preselect the value stored in database for a Spinner.
I was having in mind something like this, but the Adapter has no indexOf method, so I am stuck .
void setSpinner(String value)
{
int pos=getSpinnerField().getAdapter().indexOf(value);
getSpinnerField().setSelection(pos);}

View 1 Replies View RelatedHow do I disable (gray out, make unselectable) an item in a Spinner? I tried calling View.disable() on the associated child of the Spinner, but it remains black text (not gray) and selectable.
There must be some way of showing but leaving unselectable certain items in a spinner, right? This is a standard "menu" behavior that goes back decades. Android permits it, right? I want the user to see that certain options are possible under certain circumstances even if they are impossible at the immediate moment...exactly the way items in the main Android menu-button invoked menu can be visible but unselectable.
Is it possible to display particular entries in a Spinner list as disabled?
i.e. I want to always display a spinner with 4 entries (North, South, East and West, say), but I want to be able to disable any one of these so that is appears greyed out and not selectable.
Is this possible, or will I have to recreate the list each time, leaving out the invalid entries?
I am a newbie coder and new to the SDK. I was just playing around with an app that i made. I wanted to know as to how to retrieve the item id of the selected item from the spinner when the spinner is re- populated.
For example, I created 2 spinners, if you selected item 0 from spinner1 then spinner2 will have a bunch of items and if you selected item 1 from spinner1 then spinner2 will have a different set of items. Now, my question is that when i select item 1 from spinner 1 then the items in spinner2 dont have different ids. So how do i differentiate from the two sets of data?
To illustrate,
User selected item 0 in spinner1 -> spinner2 gets data from array1 -> item 0 in spinner2 has id '0' and item text is "apple"
User selected item 1 in spinner1 -> spinner2 gets data from array2 -> item 0 in spinner2 has id '0' and item text is "oranges"
I know this sounds confusing but i hope the right people understood it..

View 5 Replies View RelatedI created two Spinners to display the data in my application. In my first Spinner, the first item of the list is always displayed directly, but in the second Spinner nothing is displayed, even if I click on an item on the drop down view. Can anybody explain this behaviour?
Here is the code...
I am trying to get the selected item of my spinner that is populated and I am already seeing the values. when I try to use (String) s.getSelectedItem(); to get the selected item, I am receiving a handler exception on Logcat.
The spinner throwing the error is a 2nd spinner resulting from the 1st spinner's selected item (that works perfectly). In other words, user selects from spinner one and upon selection, populates spinner 2 (until here everything is fine). When trying to get the value of the selected row in spinner2 , I am receiving the error.
here's the main parts of my code...

View 4 Replies View RelatedIts me again. I tried the last hours, how to change content of a spinner. ok, lets start from the beginning.
I have three spinners. They all have initial values. The first spinner is the main spinner and the other two spinners depend on the vale chosen in the first one. So i want to update the last two spinners after making a selection in spinner one. *edit: All spinners are on the same activity.
How can i achieve this? My problem is that i can only make changes in the spinners onitemselectadapter but thats a whole new class. I cannot reach the activity where my other spinners are.
I have a spinner with items, populated via ArrayAdapter. I want to change font style for some (not for all) of spinner items, both for spinner's combobox and listbox. I guess that I need to subclass something, but I don't understand what. How can I do that?
View 2 Replies View RelatedNewbie question. I'm using a SimleCursorAdapter to populate a spinner from an SQLite table, as shown in the Android dev docs. Code...
I've set up a listener, but I can't figure out how to get the selected item text, it pulls up the SQLiteCursor, not the actual text in the spinner.Code...
Google turns up the question on several message boards, but no answers, so it appears to be a common newbie question. It may be painfully obvious to some.
I have a spinner, which mostly works. If a user selects one of the items in it, the 'onItemSelected' routine catches it just fine.
But if a user clicks the same spinner, but does not change from the already visible item that it's currently displaying, the 'onItemSelected' routine just ignores it, and the logs show:-
WARN/InputManagerService(577): Window already focused, ignoring focus gain of: com.android.internal.view.IInputMethodClient$Stub$Proxy@437948b0
I there anyway to capture someone doing this? The idea is that my spinner contains a list of names, and when a user selects one from the spinner, it gets added to a listview.
I could just add another button to get the name from the spinner, but, screen-space is already lacking and I'd rather not add anymore content.
i have an android app, with a actitity, that shows a map, with a position. This possition is updated on sharedPreferences with a service... ok, that works fine. I need that my activity implements runnable to be a thread that read's the position of sharedPreferences each 1000ms and then update the item position on the map... but it doesn't works. As i saw in debug mode, my thread doesn't work fine, ONLY ENTER ONE TIME on RUN() method... i mean that never enters into RUN() method again, only one time, cause this, the positions doesn't be updated on the map. What is wrong? why this thread doesn't work fine?
public class Locate extends MapActivity{
private TextView userText = null;
private TextView permissionText = null;
private TextView lastUpdateText = null;
private Button locateButton = null;.............
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 RelatedContext Menu seems quite handy as long as we are using an AdapterView as we can easily get selected item position in onContextItemSelected from AdapterContextMenuInfo.position Any idea how we can achieve something similar in a TableLayout? In my TableLayout, i have some TableRow and i would like to get the row index in the onContextItemSelected callback like i would do with a simple ListView. I guess i will have to register the contextmenu for each row? but how can tie the row index with the menu? i see no way to do it with registerForContextMenu.
View 2 Replies View RelatedI am creating a list .. the elements of the list are drawn from sqlite database .. I populate the list using ArrayList and ArrayAdapter ...upon clicking the items on the list I want to be able to fire an intent containing info about the item clicked ... info like the index number of the item .. using the method : onItemClick(AdapterView av, View v, int index, long arg)
I do get index of the item clicked . however it is of the list currently displayed . the problem comes when I do setFilterTextEnabled(true) , and on the app type in some text to to search some item ..and then click it ..rather than giving me the index of the item on the original list it gives me the index on filtered list..
following is the snippet of code:
myListView.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> av, View v, int index, long arg) {
Intent lyricsViewIntent = new Intent(iginga.this, LyricsPage.class);
lyricsViewIntent.putExtra("title", songList.get((int)arg).getTitle());
lyricsViewIntent.putExtra("id", songList.get((int)arg).getSongId());
startActivity(lyricsViewIntent);
}
});
myListView.setTextFilterEnabled(true);
Is there any way I can get the original index /position of the item instead of the one showing in filtered text ...when filtered.

View 1 Replies View RelatedTrying 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.

I have a ListView that is populated using an XML file. However, I want each item, when clicked, to start a new Activity related to that item. I understand how to use OnItemClick to start a Toast that shows the selected item's text. However, since the ListView is populated from an XML there is not a specific Id for each item in the list. So, how would I associate an Activity with each item in the ListView when the items do not have Ids?
