I have a proble with onKeyDown: my activity consists in a simple textView (as header) and a ListView below it, I need to go back to the previous screen when the user presses the back button.Thus, I implemented the onKeyDown method. Everything works fine if the list contains some elements, but when the list is empty the onKeyDown method is never called.

In the ListView, the space key is available as an onKeyUp event but not as an onKeyDown event.Is it possible to override the ListView's default response (i.e., page down) to the space key?The reason I ask is that my application's ListView scrolls to the text (including space characters) the user enters.Although I can implement my application's ListView scrolling based upon characters from onKeyUp(),that results in unwanted list jumping anytime the user types a space.

I've created a simple android game, based on the Lunar Lander sample, and I'm having a problem with handling key events.When the activity starts, the only keys that onKeyDown or onKeyUp get called for are the dpad up/down/left/right keys.Neither the menu, back, or dpad_center keys trigger onKey methods. However, once I've pushed one of the dpad up/down/left/right buttons, pressing the menu, back, or dpad_center keys do trigger these methods. I'm not getting any errors, or any indication of what's going wrong.It's possible that the focus is set wrong - the activity is started from a button on screen, so it could be in touchscreen mode. If that's the case, shouldn't touching the back button get me in to the right focus mode so that I can catch the event?I'm using the emulator from SDK-1.5r3.I have not been able to try this on a real phone yet.

I want it, because i'd like to create program for remote keyboard, which will be PC keyboard. PC will send to mobile throw Socket message and mobile will fire up event from message in socket. Message will contain pressed key on PC keyboard. In future i'd like to create service, which will be starting on device power on .

View 3 Replies View RelatedWhat I'm basically trying to achieve is custom global hot keys or in other words 'things will happen when I push certain buttons no matter which program is currently on top'.I assume a service is needed.I have a quick and dirty test that just tells me what has been pressed that will work if it is the active window.But obviously if I change window or go into a text box it doesn't work. If I stick it directly into a service (or an imputmethodservice) and launch said service nothing happens. (Some permissions required maybe?)Any suggestions where I'm going wrong?Or a better way of capturing which button is pressed?
View 1 Replies View RelatedI am trying to override the behavior of a TabActivity that has other Activities as children. I have made all of the children activities return false in onKeyDown so that the key will propagate through to the parent.However, this is not the case.The only key that is being recognized is the search key.Back, menu, and home are not being overridden.
View 6 Replies View RelatedI have an activity which overrides the onKeyDown method. The documentation states the following about onKeyDown: "Called when a key was pressed down and not handled by any of the views inside of the activity." The problem I have is that this method is being called even when the views inside the activity handle it. I have a button implementing a longPress listener. What I see on debugger when long clicking on the button with the center key is that first onKeyDown from the activity is called then the longPress listener from the button gets triggered. Even for Textviews, when long clicking on it with the center select, the activity onKeyDown gets triggered before the TextView processes the longclick (and shows the Input Method context menu).

View 3 Replies View RelatedSo when I get texts, gmail, completed app downloads, etc I get notification icons at the top as usual. When I slide the notification bar down to reveal the nofications and click on an item, the notification screen doesn't hide back to the top of my phone -- it just stays open. I either have to hide it manually or I have to hit the back button, which sometimes exits the app I was trying to open. 2.1 never did this for me, it always hid when choosing an item. Anyone have a solution to this? I've done a factory reset after 2.2 btw. I've also searched support to see if there was a similar problem, no similar threads.

View 2 Replies View Relatedi had an interview this morning for a job, and have an opportunity to earna great deal of brownie points with the business owners.They were thinking of purchasing some sort of electronic signature capture device (like fedex or UPS has when you sign for a package) for invoices.. BUT.I also mentioned my Droid Eris and how it can do so much. Turns out, both of the Owners have DROIDs lol.Anyways.. I want to know if anyone has seen some sort of application that can capture signatures, and either save an image to be emailed, or email directly from the app.OR does anyone know a DEV that could create something as simple as this, that I can talk to and relay updates on the APP to the owners of this company.They seemed really interested in it, and I'm pretty positive it will show a good bit of initiative in saving their company money from the get-go (on my part)
View 10 Replies View RelatedI would like to create a video recorder and so far haven't figured out how to set parameters in order to successfully go through MediaRecorder.prepare() method. Executing the following method
public void start() throws IOException{
String state = android.os.Environment.getExternalStorageState();
if(!state.equals(Environment.MEDIA_MOUNTED))
{
throw new IOException("SD card is not mounted. It is " + state + ".");
}
File directory = new File(path).getParentFile();
if(!directory.exists() && !directory.mkdirs())
{
throw new IOException("Path to file could not be created.");
}
recorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
recorder.setVideoEncoder(MediaRecorder.VideoEncoder.H263);
recorder.setVideoFrameRate(15);
recorder.setVideoSize(176, 144);
recorder.setOutputFile(path);
recorder.prepare();
recorder.start();
this.state = VideoRecorderState.STATE_RECORDING;
}
it throws an exception on line recorder.prepare(). Does anyone know how to set parameters in order to be able to capture video?
I'm having trouble getting a screenshot. I installed the SDk, Eclipse, the drivers, enable usb debugging, like the instructions say. I open DDMS and it recognizes my phone without any problems. When I try to do a screen capture, it says screen not available. In the command box it says "timeout" and "truncated reply from ADB fb data". Does anyone know what I'm doing wrong?My phone isn't rooted and is running RC33. I'm running windows vista on my computer.

I am working on key capturing events in background. i used Service to send my application back. When the application is in forground i can capture the keys and logged in a file.But when i sent it to background i am not able to get. i am aware of onKey() and onKeyDown(). and also i feel these can only capture the keys when application is foreground.
can anyone please suggest how to capture the keys while application is in background. and also without DDMS how can we capture the screen .Is there any API's
I was wondering if there is a way to take a screenshot of the current screen inside the mobile phone using a service (I know how to do it through DDMS though)
