How can I either detect that the onscreen keyboard has popped up and resize/rearrange my form elements, or have the form autoresize when the keyboard is displayed.
Right now my input field is hidden underneath the keyboard.

See this excerpt:
Code:
SIPINFO si;
int cx, cy; // Initialize the shell to activate info structure.
memset (&sai, 0, sizeof (sai));
sai.cbSize = sizeof (sai);
// Create a menu bar.
memset(&mbi, 0, sizeof(SHMENUBARINFO)); // zero structure
mbi.cbSize = sizeof(SHMENUBARINFO); // Size field
mbi.hwndParent = hWnd; // Parent window
mbi.dwFlags = SHCMBF_EMPTYBAR; // Flags like hide SIP btn
mbi.nToolBarId = 0; // ID of toolbar resource
mbi.hInstRes = 0; // Inst handle of app
mbi.nBmpId = 0; // ID of bitmap resource
mbi.cBmpImages = 0; // Num of images in bitmap
mbi.hwndMB = 0; // Handle of bar returned
// Create menu bar and check for errors.
if (!SHCreateMenuBar(&mbi)) {
MessageBox (hWnd, TEXT("Couldn\'t create menu bar"), szAppName, MB_OK);
DestroyWindow (hWnd);
}
hwndMenuBar = mbi.hwndMB; // Save the menu bar handle.
// Query the sip state and size our window appropriately.
memset (&si, 0, sizeof (si));
si.cbSize = sizeof (si);
SHSipInfo(SPI_GETSIPINFO, 0, (PVOID)&si, FALSE);
cx = si.rcVisibleDesktop.right - si.rcVisibleDesktop.left;
cy = si.rcVisibleDesktop.bottom - si.rcVisibleDesktop.top;
// If the sip is not shown, or showing but not docked, the
// desktop rect doesn't include the height of the menu bar.
if (!(si.fdwFlags & SIPF_ON) ||
((si.fdwFlags & SIPF_ON) && !(si.fdwFlags & SIPF_DOCKED)))
cy -= 26; // Height of menu bar control
SetWindowPos (hWnd, NULL, 0, 0, cx, cy, SWP_NOMOVE | SWP_NOZORDER);

Seems as if I forgot to mention that I was using C# and .NET Compact Framework.
I have found one solution for compact framework:
http://samples.gotdotnet.com/quickstart/CompactFramework/doc/inputpanel.aspx
I am desperately trying to work around some unknown problem caused by our NDIS IM driver on WM6 and HTC TyTn ( TyTn at least, but most likely other devices as well ). I started some other threads regarding different facets of this problem, and no help is coming. Now I am just trying to work around it.
in short the problem is when power events happen the WLAN will never connect.
The work around is programmatically open the control panel with STControlPanel class and press the down button 1 time then the f1 key ( right dash ). This "presses connect" on the last configured access point. This works around my problem, however, I need to detect when the access point has connected. There is a "connecting" and "connected" message for the access point in this control panel dialog ( control panel # 17 ).
My Question: Is there some way to get this text "connecting" or "connected" from the control panel #17?
I have tried wzc, ndisuio, winsock, and other "non control panel" ways to detect connected state, but the IM problem fools all these methods. The only thing I have ever seen that successfully shows when the problem has occurred is the "connecting"/"connected" status in the control panel 17.
Please Help Someone.
p.s. If I can get this worked around, we sell a commercial grade ndis intermediate driver toolkit letting you easily write plugins without any of the hard driver details. We have redirectors, transparent proxy, tunnelers, virtual adapters, lots of good stuff. Also the same plugin will work on all windows desktop platforms vista - 98, WM5/6 and CE and also linux and solaris...

Hi guys,
I am totally new at this. I mean completely raw .
I successfully put together a searchlight project by following a tutorial on youtube.
Now I want to do some work on a project that will fetch information from my employers website into the app. This information will be inform of text and images.
Here's the code I'm using in my attempt to read the remote text:
Code:
try {
URL url = new URL( "fullpath-url-to-file-dot-php" );
URLConnection conn = url.openConnection();
// Get the response
BufferedReader rd = new BufferedReader(new InputStreamReader(conn.getInputStream()));
String line = "";
while ((line = rd.readLine()) != null) {
Message lmsg;
lmsg = new Message();
lmsg.obj = line;
lmsg.what = 0;
Context context = getApplicationContext();
CharSequence text = "Hello toast! "+lmsg;
int duration = Toast.LENGTH_LONG;
Toast toast = Toast.makeText(context, text, duration);toast.show();
}
} catch (IOException e) {
// TODO Auto-generated catch block
//e.printStackTrace();
Context context = getApplicationContext();
CharSequence text = "error!";
int duration = Toast.LENGTH_LONG;
Toast toast = Toast.makeText(context, text, duration);toast.show();
}
I admit I barely know what I am doing. My attempt to download a simple line of text from a website url keeps failing.
Anyway, Can you guys give me an idea what I am doing wrong and what I should be doing instead?
Thanks
Update
I found out what the nature of the exception is.
It's a
Code:
java.net.socketexception: permission denied
exception.
Can anyone please shed some light on this for me ?
Did you add the internet permission to your manifest file?
Should be something like
<uses-permission>android.permission.INTERNET</uses-permission>
i'm not sure if this is the right place to ask this, so please direct me to the correct place if this is wrong.
I have an app that is constantly updated a notification in the status bar (changing the icon and updated text in the expanded view). The problem I am having is that when it updates the notification it will close the window I am in for certain actions. For example, if I am looking through my apps when it updates it will close that and take me to the home screen, if I am searching for something in the market it will close the search history, etc. Is there a way to have it update the icon and text in the background and not effect any currently running activity?
here is my notification code:
public void displayNotification(String msg)
{
RemoteViews contentView = new RemoteViews(getPackageName(), R.layout.custom_notification_layout);
settings = context.getSharedPreferences(PREFS_NAME, 0);
statColor = settings.getInt("txtColor", Color.BLACK);
contentView.setTextColor(R.id.text, statColor);
contentView.setTextColor(R.id.text2, statColor);
contentView.setTextColor(R.id.text3, statColor);
contentView.setTextViewText(R.id.text, "some text");
contentView.setTextViewText(R.id.text2, "some more text");
contentView.setTextViewText(R.id.text3, "some more text");
contentView.setImageViewResource(R.id.image, icon[iconIndex]);
Notification notification = new Notification(icon[iconIndex], msg, System.currentTimeMillis());
notification.contentView = contentView;
Intent notificationIntent = new Intent(this, AppService.class);
PendingIntent contentIntent = PendingIntent.getActivity(this, 1, notificationIntent, 0);
notification.contentIntent = contentIntent;
manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notification.flags |= Notification.FLAG_NO_CLEAR;
notification.flags |= Notification.FLAG_ONGOING_EVENT;
manager.notify(NOTIFICATION_ID, notification);
}
this thread can be deleted, i fixed it
Considering the
is it possible for you to tell us what you changed to fix it?
Hi,
the following code shows a notification in the menu bar. It works if I launch it from an activity, but it doesn't work if I launch it from a service (which runs when I receive BOOT_COMPLETED).
Code:
private void showNotification(String msg) {
String menuText = msg;
String contentTitle = getString(R.string.notify_title_safety);
String contentText = msg;
Context context = getApplicationContext();
Intent notificationIntent = new Intent(this, MainActivity.class);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);
Notification notification = new Notification(R.drawable.ico_notification, menuText, System.currentTimeMillis());
notification.defaults |= Notification.DEFAULT_SOUND;
notification.flags |= Notification.FLAG_AUTO_CANCEL;
notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent);
NotificationManager mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
mNotificationManager.notify(1, notification);
}
I can't find any informations about why it works from the activity and not from a service. In fact, in the very first lines of the official docs it is suggested that Services use Notifications instead of Activities (which already have the attention of the user).
Any help/previous experience?
Dumb mistake: the code was not being called because the service name was missing the leading "." in AndroidManifest.xml
