I have a ListView and to create context menu I need to know what view created the menu. The View parameter of onCreateContextMenu is always the same and equals the first view in ListView. Is there any way to get position or id of view that called onCreateContextMenu?

I have a form with several Views on it, the last one is a Spinner that is bound to an adapter to get it's data from a Web Server via a POST request, at the end I append an additional entry for "Other...". If this option is selected on the spinner, a new EditText View at the bottom where the user enters a custom value, I've managed to get the EditText View to show on the screen, but it's positioned at the very top, over my other Views and I can't seem to find the way to make it appear at the bottom, below the Spinner as I want it to, here is the code I have so far:
EditText suggestCarrierField = new EditText(getBaseContext());
suggestCarrierField.setLayoutParams(new ViewGroup.LayoutParams(
ViewGroup.LayoutParams.FILL_PARENT,
ViewGroup.LayoutParams.WRAP_CONTENT));
suggestCarrierField.setHint("Suggest your carrier");
((AbsoluteLayout) findViewById(R.id.createAccountView)).addView(suggestCarrierField);
((AbsoluteLayout) findViewById(R.id.createAccountView)).invalidate();
I'm using a ListView that is setup like this:
CODE:................
In my code I add an OnItemSelectedListener to the ListView like this:
CODE:................
my Activity implements the listener like that:
CODE:........
My hope was, that I would see this debug output the moment I click on something in the list. But the debug output is never shown in LogCat.
CODE:..........
I want to catch how much the listView is scrolled, so I extend ListView. I am able to scroll the list. But OnScrollChanged is not called. For ScrollView and HorizontalScrollView OnScrollChanged is called whenever it scrolls. Which function is triggered when we scroll a ListView.
I'm trying to create a context menu that changes the available options depending on which row was clicked. But I can't figure out how to get the row position in the listview for row that was clicked, until after the menu is created.

View 1 Replies View RelatedI'm subclassing Android's view class, but whenever I make an instance of the view from another class, the constructor never gets called (or so it seems). I've implemented both public myclass (Context context) and public myclass (Context context, AttributeSet, attrs) I can't figure out what I'm doing wrong. Do I need to override onDraw and onMeasure?
View 1 Replies View RelatedI have a ListView whose position should be changed automatically along with the data. So, when the adapter's data has changed (adapter is calling notifyDataSetInvalidated), I'm calling setSelection. This has no effect. If the call to setSelection is done later (e.g. in a click handler) it is working.
The second problem is, that the ListView maintains the scroll position of the list although the data is completely invalidated, that makes no sense IMO.
It looks like a call to layoutChildren before the call to setSelection does help in this case, but layoutChildren is protected.
What is the correct way to do this?
I'm using Eclipse and have an emulator running Android 2.1 and my IntentService. I'd like to step through my onHandleIntent() overridden function. I've put in a breakpoint on the first statement of the function, which is Context context = getBaseContext();. When the intent is called the program just fails and does not go to debug view in Eclipse.
View 1 Replies View RelatedI have a View that I've placed into a ScrollView.The View paginates text.If the text changes, then the height of this view will also change (expand or contract, depending on whether the new text takes more vertical space or less).For debugging, I draw a rectangle around the view to show its current size. After I repaginate, I cannot get Android to cause the View to change its size -- I have tried calling measure() myself, calling requestLayout(), and calling forceLayout() -- even though my overloaded onMeasure gets called, and calls setMeasuredDimension() with the correct values, the view remains the same size as it was before repagination. What am I missing?
View 2 Replies View RelatedI have a weird problem on progress dialog: I have 2 views: Login View and say, Display View. In Login View, when I click the 'Login' button, a progress dialog is created (new ProgressDialog(...)), shown and stored in a variable 'mProgressDialog'. After login, the dialog is dismissed and some information are displayed in Display View (Login View hides). Now I want to display another progress dialog when 'Update' button is clicked and when the update is done, dismiss the dialog and display new information. So I use: the Display View for a blink and then shows the Login View. I tried to change the view etc. but same problem happens over and over again. So I am thinking it might because one activity can only be assigned to ONE progress dialog and no matter how you re-create it you still get the same progress dialog. And the dialog is linked to a certain view which will be shown automatically when the dialog dismisses.

What I have now is a layout that includes a list view at the bottom. All of the items in the layout above the list view remain fixed as you scroll through the list view. I would like the entire page to scroll so for example when you reached the bottom of the list you would no longer see the items above the list view.

I am new so I may not explain the situation well. Please let me know if you need more info.
I am trying to implement a listview like this:
[textview][button][checkbox]
[textview][button][checkbox]
[textview][button][checkbox]
[textview][button][checkbox]
I want other checkbox unchecked automatically when I click one of them. So it is like a single choice. I write following codes which can implement multiple choice but when I try to switch it to single choice I got trouble.
in checkBoxOnClickListener I cannot find other (checkbox)view and toggle them. Any suggestion pals? Let me know if you think my express skills poor. code...
I have two textviews, a listview (this is a listactivity, by the way) and a datepicker. All is supposed to be displayed in this order, vertically.
The problem is that the ListView is pushing the datepicker below the screen, to the depths of the unseen world. I want the datepicker to have its own space, fixed at the bottom, while the listview grows as needed, but still allowing datepicker to have its own space.
+/- like this:
~~~~~~~~~~~~~~~ screen top
TextView 1
TextView 2
|
|
|
| ListView [*]
|
|
|
DatePicker (stays here no matter how much List grows or shrinks
~~~~~~~~~~~~~~~ screen bottom
[*] -> This listview will scroll a lot, but won't hide datepicker!
I know it's very lazy to ask for ready code, but could you guys share a light? This is driving me crazy. I've tried millions of combinations I believe.
In Android, what functionality do ListActivity and ListView provide beyond a regular Activity and View?
View 2 Replies View RelatedI have a ListView backed by customized ArrayAdapter where each item has 2 LinearLayouts - one I call head, and the other one - body. The body is hidden (gone) until user clicks on the row at which time it slides out. The second click (on the head) will hide the body. However if user clicks on the body it brings another activity. All of this works just fine, here comes the problem.When user presses on body I want a visual indication of the action just the same way as regular list item will flicker an orange background when pressed. I'm not getting this by default since (my theory) the onPress event is intercepted by body's view and not processed by the list item.The first thing I tried was to execute body.setBackground('#ff00ff') (never mind the color) in onPress event. That didn't work since (I suspect) there's no repainting after the call. Then I dig a little bit more and decided to use <selector/>-based background. I defined body_background.xml in drawable folder and assigned that to the body's background property.
There I noticed that background will only change if the even is processed by the list. For example if I set <item android:state_selected="true" android:drawable="@drawable/selected"/> then when I press on the head - the background of both elements (head and body) will change, however when I press on body - nothing. So to summarize my question.how do I change background of the child element in the list item if I assign custom onClick handler to it?

Code:

The problem is this line right here
list=(ListView)findViewById(R.id.listView1);
which gives me a Cannot cast from View to ListView and I checked the xml file and it is a ListView so I don't know what the deal is.
I'm sure this is an obvious one but I'm at a loss. I'm using my own layout for list rows, all well and fine. but the moment I add a checkbox view to the rows layout only the checkbox responds to user selection. I'd like for the checkbox to change state if the user taps anywhere within a given row. (as with android prefs)
