When I long press the search key, I get a list of apps to choose from. Is there a way to remove some of the entries from this list? I know I can assign one as a default, but I don't want to do that. I want to leave a couple of the options, but I don't need Handcent and Dialer One to show up there.

I am on my first Android application and I am on a timeline so details and examples will be useful since my knowledge is still minimal. 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...

I'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.

I'm trying to tackle a problem that seemingly many Android developers have, which is how to intersperse lists with non-list data, in one big scrollable pane.The model I have in mind is the screen for an individual app in the Market. You have a big description, a list of a few lazily loaded comments, and then some individual items that do different things, like visit the developer's web page, call them, etc. And then in between them all, are nice section headers.Emulating this approach seems to be extremely hard. I've read enough SO answers and mailing list posts to know not to put a ListView inside of a ScrollView, but I want the same effect without using addHeader() and addFooter() with very complex header and footer views. I've tried using a LinearLayout that I stock with views myself, but I can't get the pleasant click effects that default list items have (the orange background, white for long-click, etc.).

I 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.

By Default in the Listview,focus will come on the list item.Instead of that, can I get only the border to the list item?I can achieve this by using a transparent image as a list selector.Is there any other simplest way to achieve this requirement?

I'd like to know if there's any way I can remove an specific app from the Play Store list, without uninstalling it. Or if there's a way to remove this app from the apps that are checked for updates.
The reason is that I have a Motorola Defy+ and I like the stock music player, which is just fine. There's an update called Tune Wiki which is, in my opinion, pure crap. So in order to install updates of all my other apps I have to install one by one, because I can't choose the option "update all" since it would update the music player too.

Anyone seen a general list or data manager app for Android? Not looking for a to-do list or task list - but a general list manager where I can define my own tables and fields, edit data, filter, sort, etc. Syncing to a PC app would be great, but I don't really expect that.If anyone has used Listpro fom Ilium Software, on Palm or Win Mobile - that's what I am looking to replace.I may end up using Excel spreadsheets with Documents to Go from Dataviz - and some general sync tool for PC to phone data sharing - but Listpro was so good, I'll miss it!

I have got list that is filled with data from internet.
Datas are downloaded in chunks. At the end of the list next portion of data is downloaded and added to the list.
I'm detecting list end with help of onScrollListner:
CODE:........
I would like to addLoading... row when datas are being downloaded. Something similar to Gmail loading row at the end of the list.
I know that I can hack adapter.getCount() to return size + 1 and force adapter.getView to display loading... at the end of the list.
How can I do that in more elegant way?

I have my phone set to display only numbers on the SIM (or only on the phone.. doesn't really matter) so that in the contacts app and the contacts section of the phone app I don't have duplicates of everything. However, even when this is working correctly, in the contacts section of the text messaging app, it still shows two of everything.
