I'd like to create a very simple android activity that takes a file path on the sd card and displays the contents of that directory in a listview.
I know how to get a list of the files via File.listFiles() which returns an Array of File objects. What I want to know is how I can adapt that array to a ListView. Would an ArrayAdapter be the right thing to use and how would I do that?

I'm creating an Android app, where the user starts out seeing a list of questions. When the user clicks a question, I would like to show him a new clickable list, containing that question and its answer alternatives.
My questions reside in rows in the database. The questions live in the first column, while the answer alternatives live in the following columns.
I've managed to display any single element from the row when I click a question in the list, but how to display more than one completely eludes me.
This is the relevant source code in the intent entered when the user clicks a question:
private void fillData() {
Bundle extras = getIntent().getExtras();
Long id = extras != null ? extras.getLong(QuestionsDbAdapter.KEY_ROWID) : null;
Cursor questionsCursor = mDbHelper.fetchQuestion(id);
startManagingCursor(questionsCursor);
String[] from = new String[]{mDbHelper.KEY_QUESTION,
mDbHelper.KEY_ALT1,mDbHelper.KEY_ALT2};
int[] to = new int[]{R.id.text1};
SimpleCursorAdapter questions =
new SimpleCursorAdapter(this, R.layout.questions_one_row,
questionsCursor, from,to);
setListAdapter(questions);}
This displays only the question. If I put one of the answer alternatives first in the 'String[] from ...' statement, that gets displayed instead.
so I'm using launcher pro which shows me that theres 43 emails in my inbox but when I open the gmail app, there are NO new emails.
I have the unread gmail app and when I open that one it says "no connection"
finally after 3 hours of not receiving emails as I'm typing this I get a new email alert, then they all start piling in.
Why is this.
We shouldn't have to use the "unread gmail" app in the first place but I have had to ever since I got my D1 and it's the same on the D2.

On my DroidX, Google Sky doesn't show up in my list of applications, but if I search for it, it does. I can launch it from the search results. I can also add an application widget to the home page and select Google Sky in its settings as the app to launch. Why doesn't it show up in the list of applications (The icon-based list you get when pressing the triangle-in-a-circle icon from the home page)?
View 4 Replies View RelatedI am still in the process of learning and customizing this phone so there may be a famous app that takes care of this but I did a search and found nothing. I am not a big fan of how the contact list shows friends from facebook/gmail/Phone. I only want it to show contacts that I have personally added on my phone. Is there a way I can arrange this. I have it to where it remembers phone contacts only when I hit contacts but as soon as restart, it goes right back to all contacts. It also comes up when I try to text someone or in the contact section of the dialer. I just dont like this. I don't mind that they are there, persay, but I don't want it to be default all the time. Is there a way to change this?

View 2 Replies View RelatedI have a piece of code that creates some APNs with this call: -- getContentResolver().insert(Uri.parse("content://telephony/carriers"), apnData); The APNs are correctly created both on fw 1.1 and 1.5 (a query correctly returns them) but on fw 1.5 they don't show up in the device APN settings screen.
Has anyone any hints on the reasons of this behavior?
I just installed Handcent on my Droid and am having two problems. I checked the settings and can't figure out why these things aren't working properly.
1. The pictures from my contact list do not show up next to the texts. Every one of my contacts has a silhouette and question mark in place of the picture - which shows up fine in the default messaging app.
2. When a new text comes in, the new text notification pops up on the taskbar. I do not receive a handcent notification icon, and if I open the text with Handcent, the default message notification does not disappear.
Here is code of Notepad Tutorial . It only display title in the list. I want to display two or more fields of DB to the list.code...

View 1 Replies View RelatedI am trying to implement a drop down list when a button is clicked.
So, I have a text view and a button in a navigation bar(nav.xml) and a corresponding list view. This navigation bar is included in another page( products.xml)
when the button is clicked i get the list view right below the button(which is what i want to achieve) but its my moving all the contents on the current page downwards, even the text view which is placed in nav bar moved downwards.
I am totally new to Android, any sample examples or a way how to achieve it?
I have two phones, one running 1.5 and the other on 1.6. When I connect the 1.6 device via usb, DDMS recognizes it and in the top-left pane shows: HT842....... | Online | 1.6, debug
It then lists the individual processes, I can select them and use various tools like allocation tracker.
But when I connect the 1.5 device, DDMS recognizes it but shows: HT95A....... | Online | 1.5
But it does not show any of the processes on the device, so I am not able to do use allocation tracker and such. The sysinfo tab works, and I can monitor logcat with filter and such in the bottom pane.
What am I missing here? Obviously the 1.5 device has USB debugging enabled. Why does it not show 'debug' in DDMS? I'm using SDK 1.5_r2 on linux (Ubuntu 9.04), if that makes a difference.

View 6 Replies View RelatedWhen I try and send a new message, or forward a message some of my contacts don't show up on the drop down list. I'll type the first few characters of their name and it will bring up a list of the names in my contacts directory but some names are missing so I cannot send a text in the normal manner (I know I can find the contact through the dialler and send a message that way but that doesn't help if I try and forward a message). I've looked to see if there are any strange spaces in the names etc but I cannot fathom out why some of my contacts are missing from the drop down lict in messages. Anyone else have this problem or know a solution?
