In the getview function im using the convertView to set up a OnClickListener. This OnClickListener work well when I am touching the screen but if I use the trackball of the HTC Desire, I see the row flashing on the screen, but the OnClickListener is not called...

I am facing some problem Like:
Scenario:Three buttons enabled by on click event.
-I am using sliding drawer... on which no of buttons are there. -When sliding drawer is opened...its overlapping the preveously defined three buttons.
My problem is... when i am clicking on sliding drawer ... the below button is activated and accordingly it goes to next activity...
Means ... i expect if one view is on top of another view... the lower view should not work.
I have an activity, where the ListView holds customized linear layout elements for each row. One of the rows has a button defined as:
<Button
android:text="Pick a contact"
android:id="@+id/btnPickContact"
android:layout_width="wrap_content"
android:gravity="center_vertical"
android:layout_height="wrap_content"></Button>
Then in java, I have this code:...............
This should be a simple question because I couldn't get the answer from Google . I have ListView in a LinearLayout . I need to handle the click event to allow user click on the LinearLayout to trigger some function. I try to add onClickListener to the LinearLayout , and it works only when I click outside of the ListView . How do I let the click event on ListView propagate automatically to be handled by the Listener of the LinearLayout?

Is it possible to check some condition inside onCreate() of an Activity and display an AlertDialog?
I am creating an AlertDialog anonymously in Oncreate() and calling show on that instance but the AlertDialog is never displayed.
I have a ListView whose rows are formatted by me. Each row has a mix of ImageView and TextView. I have also implemented my own adapter and am able to draw each row through it.
Now, I would want something like this-
User clicks on an ImageView (not anywhere else on the row, but only this ImageView should respond to clicks)
I get to know the position of the row whose ImageView was clicked.
I have tried many things for this and have wanted my code to be as efficient as possible (in terms of overkill).
Currently i can capture the click event on that particular ImageView only, but I can't know which row was clicked.
I have provided an attribute in the Row XML like this-
CODE:..................
And in my code, I have a method like this:
CODE:..............
I can get the parent row (perhaps) but am not sure how to go further from here.
If you want a button to provide haptic feedback (ie, the phone vibrates very briefly so you can feel that you really pushed the button), what's the standard way to do that?
It seems you can either explicitly set an onClick() event and call the vibrate() function, giving a number of milliseconds to vibrate, or you can set hapticFeedbackEnabled in the view.
The documentation seems to indicate that the latter only works for long-presses or virtual on-screen keys: http://developer.android.com/reference/android/view/View.html#performHapticFeedback(int)
If that's right, then I need to either make my button a virtual on-screen key or manually set the onClick() event.
Also, if I want the vibrating to happen immediately when the user's finger touches the button, as opposed to when their finger "releases" the button, what's the best way to accomplish that?

I could not figure out how to implement two basic functionalities with the expandable lists: 1. The onClick for the child 2. Using linear layout for the children, so that I can have multiple clickable items in same row under the parent item
Can somebody help me with some sample code for the above?
I'm trying to find a way to access private files created by other packages.According to the dev site (plz see the following), I can read/write files of other packages if some flags are set on the create of those files, but I don't know how. Can I just open those files with Context.openFileInput(or Context.openFileOutput)? Do I need a different way for those three cases? By three cases, I mean getSharedPreferences(String, int), openFileOutput(String, int), openOrCreateDatabase(String, int, SQLiteDatabase.CursorFactory).

private static final CharSequence[] skill_levels = { "Rookie", "Average", "Expert" };

I am trying to figure out what is the best way to go about creating dialogs. I can either create my own Dialog class (which, to me, is more clean and organized), or I can use AlertDialog.Builder (which would be done inline, and funky looking)... What are the positivies and negatives of either implementation?

This doesn't seem like the right behavior. I've tried it with other views inside the FooView hierarchy and findViewById() always returns null.
For the life of me I can't figure out what I'm doing wrong.
I don't know if it's very clear, but I'm trying to do something when the "next" (bottom right corner of the keyboard) is pressed, and i can't find its keycode.
I have tried to look for "next" or "enter" in the keycodes but nothing really relevant... does anyone know?

I have read the Android UI trick 2 on Android developers, which tells people how to include a layout in another layout file multiple times, and give these included layouts different id. However, the sample here is overwriting the layout id, not the id of the views IN this layout. For example, if the workspace_screen.xml looks like this: And I include it three times in another layout file. Do I end up with three TextViews with id firstText, and another three with secondText? Isn't there an id collision? And how do I find the secondText TextView in the third included layout with findViewById? What should I input in the findViewById method?
View 1 Replies View RelatedI'm attempting to override an Android View class to tweak the functionality just slightly. But I need to modify a field that does not have a setter method. I've placed the subclass in a package called android.widget. Why can't I access any of the package-private member fields? I notice that the compiler says they "cannot be resolved," rather than not being accessible. Does this have something to do with how Android.jar is built?
View 2 Replies View RelatedI am wanting to query the members of a given playlist. I have the correct playlist id, and want to use a managedQuery() to look at the playlist members in question.
What I have is this: Code...
I don't know what the volume argument needs to be. I've tried this: MediaStore.Audio.Playlists.EXTERNAL_CONTENT_URI.toString() for the "volume" argument.
That gives me back a valid content URI that looks like:
content://media/external/audio/playlists/2/members
However, my cursor comes back null. I probably am way off base -- I know what I want to do is very simple.
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.

View 3 Replies View RelatedSo I've been extremely frustrated by this for a long time now.I've posted before, but can't seem to find a good solution. My goal is to have something pretty much exactly like the installed application details page in the Android Market.I need a list of items displayed along with other content above the list, and would like the content above to scroll up along with the list (exactly like the application details does for the "My Review" and other descriptive info).Due to responses to my previous posts, I came to believe that it really wasn't possible to do this with a ListView.So rather than using a ListView, I refactored my code to use a simple LinearLayout and add individual View items to the list, thinking I could just set each View as clickable and add an OnClickListener to each View in the LinearLayout.That's not working at all though, and now I'm getting even more frustrated.If someone can help me get the OnClickListener working, then I think it'll work, but I do need a separator for the LinearLayout.How do I add a separator like the one used for ListView to my LinearLayout?
