[android-beginners] Re: Android app communicating with the "outside"
I don't know if the source for the android tools has been made
available or will be made available, but that would be something to
watch for in the future if you needed some way to write to your
computers hard drive. You could also try to use the sdcard. There
might be a way to mount it in your computer. That way, you could write
to the sdcard from your client code, then access it in your computer.
/data/data//files/out.txt is on the emulator file
system. You can log in with "adb shell" or you can copy the file from
the emulator with adb pull.
So with your http post, you were using the actual ip address of your
computer in the url? That should work.

[android-beginners] Re: Android app communicating with the "outside"
I can't write to the C: drive?! That sucks. Are there any other
alternatives? I need the Android app to relay info to the outside
world (app write data that outside programs consume). These are the
two ways I came up with : ).
When I said I couldn't find this file, I meant the computer file
system. How do I access /data/data//files/
out.txt? Can an independent java program be able to read from this
file?
As for the http post, from an independent client, it works (I had to
of course change 0.0.2.2 to localhost). The post hits a webapp
implemented in Web Works. I have this code sitting inside the
onCreate() method of an Activity. It doesn't give any on screen
exceptions. Just no result on the server side.
Thanks again,
Yi

[android-beginners] Re: Android app communicating with the "outside"
ok, here's my advice:
- You won't be able to write to your c: drive afaik.
- You can't find the file on the file system? Do you mean your
computers file system or the emulators file system? It should be on
the emulator in /data/data//files/out.txt.
- I don't think there would be a permissions problem for either the
file or http examples you gave.
- Your http post code looks ok at first glance. Are you getting any
exceptions with it?
Why do you need to write something to C: anyway? Are you working on
some kind of development tool?

[android-beginners] Android app communicating with the "outside"
Hi everyone,
I have an app that needs to write to a file that is accessible from
programs outside of Android. The snippet of code is as follows:
OutputStreamWriter osw = new
OutputStreamWriter( openFileOutput( "out.txt",
MODE_WORLD_READABLE ) );
osw.write( "picture taken: " + picId );
osw.flush();
osw.close();
Android doesn't allow me to write to the outside, for example the C:
drive and I'm not able to find this file anywhere on the file system.
I'm guessing its some kind of permissions problem. I would like to be
able to write to anywhere on the file system I want. Is that
possible?
Also, since what I tried above didn't work, I also tried writing a
Http Post and posting the info to a webapp. This code works
independently but when put inside an Activitie's onCreate() method, it
doesn't work. Again, I'm guessing it has to do with permissions:
String data =
URLEncoder.encode( "signinUserAccount.userName", "UTF-8" ) + "=" +
URLEncoder.encode("a", "UTF-8");
data += "&" +
URLEncoder.encode("signinUserAccount.password", "UTF-8") + "=" +
URLEncoder.encode("b", "UTF-8");
URL url = new URL("http://10.0.2.2:8080/GoogleCamAF/
userAccountView.action");
URLConnection conn = url.openConnection();
conn.setDoOutput(true);
OutputStreamWriter wr = new
OutputStreamWriter(conn.getOutputStream());
wr.write(data);
wr.flush();
Any advice would be greatly appreciated!
Yi

[android-beginners] Displaying data from the database in a Spinner
Hi,
I'm trying to display items from a database in a Spinner. I've read
other posts on this but my items still aren't showing up and none of
the posts show a complete solution.
To help debug the error, I added a ListView and the items from the
same db call display without any problem in the list. Thus, there's
some little detail that I can't find in my code for the Spinner. I'd
certainly appreciate someone pointing out the error.
To try to help me debug the code, after selecting an item from the
"invisible" list, I print out the selected item and it displays:
[EMAIL PROTECTED]
I can see that the spinner has lots of items and I can scroll through
them but they don't display anything.
Code:
public class TestListCursor extends ListActivity {
private DBInterface mDbHelper;
private Cursor notesCursor,
spinnerCursor;
Spinner spnItems;
TextView tvItem;
SimpleCursorAdapter _itemsAdapter = null;
Button btnSel;
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.notes_list);
this.spnItems = (Spinner) findViewById(R.id.spn_NL_items);
this.tvItem = (TextView) findViewById(R.id.tvNLSelection);
this.btnSel = (Button) findViewById(R.id.btnNL);
mDbHelper = new DBInterface(this);
fillSpinner();
fillData();
this.btnSel.setOnClickListener (new View.OnClickListener() {
public void onClick(View v) {
TestListCursor.this.tvItem.setText(TestListCursor.this.spnItems.getSelectedItem().toString());
}
});
}
private void fillData() {
// Get all of the rows from the database and create the item
list
notesCursor = null;
notesCursor = mDbHelper.getItemsCursor();
// Create an array to specify the fields we want to display in
the list (only TITLE)
String[] from = new String[]{DbAdapter.ROUTE_NAME};
// and an array of the fields we want to bind those fields to
(in this case just text1)
int[] to = new int[]{R.id.text1};
int i = 0;
if (notesCursor != null) {
startManagingCursor(notesCursor);
// Now create a simple cursor adapter and set it to display
SimpleCursorAdapter notes =
new SimpleCursorAdapter(this, R.layout.notes_row,
notesCursor, from, to);
setListAdapter(notes);
}
}
private void fillSpinner() {
spinnerCursor = mDbHelper.getItemsCursor();
if (this.spinnerCursor != null) {
MMFLog.log("Workout fillItemsSpinner cursor items: " +
this.spinnerCursor.count());
startManagingCursor(this.spinnerCursor);
this.spinnerCursor.next();
// Create an array to specify the fields we want to
display
in the spinner (only Name)
String[] names = new String[] {DbAdapter.ROUTE_NAME};
int[] to = new int[]
{ android.R.layout.simple_spinner_item };
// Now create a simple cursor adapter and set it to
display
this._itemsAdapter =
new SimpleCursorAdapter(this,
android.R.layout.simple_spinner_item, this.spinnerCursor, names, to);
this._itemsAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
this._itemsAdapter.bindView(this.spnItems, this,
this.spinnerCursor);
this.spnItems.setAdapter(this._itemsAdapter);
} else {
Toast.makeText(this, "error: items cursor is null",
Toast.LENGTH_SHORT);
}
}
}

[android-beginners] Showing Default text in EditText fields
I've seen this in the map application and other apps where EditText fields will display some default text in grey when the fields are empty. Then if a user starts to enter text into the fields it clears the default text out, and shows the text they entered in black. I was looking through the API and trying to see if I could do that easily, but I don't see it. Is there an example out there of how to do this? Does the API support this out of the box?

[android-beginners] Re: How to make rows smaller in ListView?
I'm sorry but I thought more about this and it simply doesn't make any sense. This ListView currently only shows 6 rows at once. My iPhone, which is 320 x 480, shows 9 rows in the Notes app and 8 in Safari's bookmarks view. The rows are simply WAY too big. Is there really no way to make them smaller?

Not sure if my last message came through. But I think the problem you
have is as follows...
change
AnswerTextView[0].findViewById(R.id.cau_1_answer_grammar);
to
AnswerTextView[0] = findViewById(R.id.cau_1_answer_grammar);

Hi, You may want to look at expandable lists( these come close to bulleted lists): http://code.google.com/android/samples/ApiDemos/src/com/google/android/samples/view/ExpandableList1.html Android does not have any other view for using bullets(if you are talking about using html /, you can use the webview).

[android-beginners] Re: Assess other variable from other class in the same package !
Yes, you would have to have an instance of each, unless the variables
were defined as static. In your case, you wouldn't need to specify
public. The default modifier will work since they are in the same
package.

[android-beginners] Re: how to show alerts
Hi Raul,
You could use the Toast.cancel() or Toast.setDuration() method to dismiss
the alert programatically.
To call Toast from a thread other than the main UI thread you can create a
handler in the main UI thread, and then post the runnable in which your
Toast is created to this handler.
final Handler mHandler = new Handler();
Thread t = new Thread() {
public void run() {
mHandler.post(mUpdate);
}
};
t.start();
}
final Runnable mUpdate = new Runnable() {
public void run() {
Toast.makeText(Spad6.this, "New message",
Toast.LENGTH_SHORT).show();
}
};
Thanks,
Megha

[android-beginners] Re: Selecting from a listview...how do I know what I clicked on?
Hi, You should use the onItemSelected() method of the ListView, which is invoked when you select an item with keypad. Sample code: http://code.google.com/android/samples/ApiDemos/src/com/google/android/samples/view/List7.html Thanks, Megha On Tue, Apr 1, 2008 at 2:42 AM, Salsa bob <[EMAIL PROTECTED]> wrote: > > I have this Listview with 5 elements in it, and when I select and pick > one of them, I want to change to a different screen, depending on > which item I picked.

[android-beginners] Re: how to show alerts
I see Toast being simmilar to AlertDialog. Still it is not a solution for
me. The docs say the time the Toast is visible could be customizable. I
don't see how. Anyway, I still get to the Looper problem. The API demos
indicated make use of a Toast in the event thread. I need to show it in
another thread. eg:
public void run(){
// show information dialog 1
// try to do lengthly_stuff_1
// hide information dialog 1
// if lengthly_stuff_1 failed {
// show information dialog 2
// do lengthly_stuff_2
// hide information dialog 2
}
}
Writing this e-mail, I got the idea to show the alert or Toast in the event
thread ( runOnUIThread() ). It works and like this I can avoid the Looper.
Ok, but what can I use to hide / dispose it exactly when I want and to do
this programatically ?
regards,
Raul

The rows currently have an appropriate size for devices with a touch screen. The size of the UI on your computer screen is much bigger than its size on an actual device.

[android-beginners] Re: how to show alerts
Hi, You can dismiss the dialog shown by showalert() by clicking the back button on the emulator, if your dialog is cancelable. http://code.google.com/android/reference/android/content/Context.html#showAlert(java.lang.CharSequence,%20int,%20java.lang.CharSequence,%20java.lang.CharSequence,%20android.content.DialogInterface.OnClickListener,%20java.lang.CharSequence,%20android.content.DialogInterface.OnClickListener,%20boolean,%20android.content.DialogInterface.OnCancelListener) If you want a show an alert which disappears automatically after a specified duration or disappears on calling cancel(), consider using the Toast class instead. Sample code for using Toast: The ApiDemos > apps> AlarmService.java,AlarmController.java Hope this helps!

[android-beginners] Re: Access other variable from other class in the same package !
Dear Pepel !
I am even beginner in Java and thank you very much. I get well your
instruction. I still need your help, please see :
In Cau_1, I set instance like this :
...
char Cau_1_Answer;
protected char getCau_1_Answer() {
return Cau_1_Answer;
}
protected void setCau_1_Answer(char cau_1_Answer) {
Cau_1_Answer = cau_1_Answer;
}
In the class that access :
char[] AnswerList = new char[10];
...// (1)
protected void onCreate(Bundle icicle)
{
super.onCreate(icicle);
setContentView(R.layout.result_grammar);
AnswerList[0] = Cau_1_grammar.getCau_1_Answer; // AnswerList[0]
assignment
...
The error is Cau_1_grammar.getCau_1_Answer cannot be resolved
If I place AnswerList[0] assignment at (1) , the error is Syntax error on
token ";", { expected after this token after the array initialization.
How can I fix it ?

[android-beginners] How to make rows smaller in ListView?
Hey, I am confused as to why in the ListView screenshot shown below, the rows are quite small: http://code.google.com/android/reference/view-gallery.html Yet when I run the sample project it comes from, List1.java, the rows are about twice as high: http://code.google.com/android/samples/ApiDemos/src/com/google/android/samples/view/List1.html How can I modify it to make it look like the screenshot?

[android-beginners] Re: Assess other variable from other class in the same package !
The class that wants to access the variables from the other class can only
access them through an instance of the class! (or if the class Inherit from
the Cau_1.. Cau_10 classes)

[android-beginners] Re: how to show alerts
never mind that one. it seems to work if I put loop() at the end of the logic. I have another related problem now. I want to show two alerts, one after the other, as the logic advances. But I can not get rid of the first alert. Calling cancel() or dismiss() or both does not work. How can I loose an alert programatically ? regards, Raul On Tue, Apr 1, 2008 at 4:07 PM, Raul Bocter <[EMAIL PROTECTED]> wrote: > Hello, > > > I am trying to show alerts while doing some logic in the background.

[android-beginners] how to show alerts
Hello, I am trying to show alerts while doing some logic in the background. I want to do this in a new thread (not the UI thread). I don't understand how this should work. As I try to show the alert it throws an exception saying i have to call Looper.prepare() first. Ok, I call prepare(). The alert does not show until Looper.loop()gets called. But after loop(), the thread is stuck there. It will not go further.

[android-beginners] Re: Need help in debugging null pointer exception
1. Open the Debug perspective in Eclipse
2. Choose the 'Breakpoints' view tab.
3. Select the 'Add Java Exception Breakpoint' and choose
NullPointerException.
4. Launch your activity, either by using 'Debug As...' or attaching
the debugger to a running instance via DDMS.
5. Execute the offending workflow. It will break on the line that
caused the NPE.

[android-beginners] Re: Possible to create 2 ListViews side by side?
Why to have two listViews?
If I can suggest, I think this way is simpler:
you can try to do it by creating a component composed by the item +
the button or whatever, and then add the component to the ListView.
I mean:
(ListView)
(Item1 [Add][Text link][TextLink])
(Item2) [Add]...)
..

[android-beginners] Assess other variable from other class in the same package !
Hi !
I have 10 classes :
Cau_1.java containing variable char Cau_1_Answer
Cau_2.java containing variable char Cau_2_Answer
Cau_10.java containing variable char Cau_10_Answer
and another class with char[] AnswerList = char[]{Cau_1_Answer,
Cau_2_Answer,...,Cau_10_Answer}
Why does the class with AnswerList get error *can not resolve* *Cau_1_Answer,
can not resolve Cau_2_Answer..*.?
I keep all the default modifier because they are in the same package. Even I
change in public, it doesn't work either ?
What I did wrong and how to resolve ? Thanks for help !

[android-beginners] Selecting from a listview...how do I know what I clicked on?
I have this Listview with 5 elements in it, and when I select and pick one of them, I want to change to a different screen, depending on which item I picked. However, onListItemClick seems to only detect touchpad clicks, and doesn't do anything if I try to select and pick an item with the keypad. What's a good method to return the position of the focus when it clicks down on something? Onkey can only get back the entire listview, and not the element in it. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Beginners" group.

[android-beginners] Re: Possible to create 2 ListViews side by side?
Thanks! I have a followup question: is there a way to make the second
list remain aligned with the first list as we scroll down? I'm trying
to make the second list comprise of a set of buttons or text links
that would be associated with each item in the first list?
So like this:
(ListView 1)(ListView 2)
Item 1 [Add]
Item 2 [Add]
Item 3 [Add]
Is this possible with Android?
Thanks again!
