View 2 Replies View RelatedMy girlfriend recently got the HTC Tattoo (running Android 1.6) and she's having major issues with the alarm on the Clock application. Whenever she sets the alarm to wake up in the morning, it doesnt go off at the desired time. There's no sound or not waking of the screen. The alarm does finally sound when the screen is woken, and this can be 20 minutes or so after the alarm *should* have sounded! It works ok if the alarm is set to go off in 5 minutes time or so, but it seems like Android forgets to ring the alarm until the screen is woken and then does it.Can anyone provide any insight into this issue? I have seen that there are other threads where the alarm doesn't work but they dont cover this behavior.

In some cases, I want to catch the message when a user presses the "hang up" button on the phone, and then discard the message before it reaches the OS.
I use onLongClick and onClick events of a button to get user inputs. Whenever; the user long click and triggers onLongClick event, the onClick event is also triggered. I couldn't find my problem. The code of two methods are shown in below: Code...

I am struggling with the done button on the soft keyboard. I can't get the soft keyboard Done keypress to hide the keyboard. From another button, it works perfectly with imm.hideSoftInputFromWindow(editText.getApplicationWindowToken(), 0);
but the onKeyListener does not function the way I want. When I hit the editText, the soft keyboard shows up and its content is cleared from characters. The main.xml:
<EditText android:id="@+id/answer"
android:layout_gravity="center_horizontal" android:textSize="36px"
android:inputType="phone" android:minWidth="60dp" android:maxWidth="60dp" />
The Java file:
private EditText editText;...
editText = (EditText)findViewById(R.id.answer);
editText.setOnClickListener(onKeyboard);
editText.setOnKeyListener(onSoftKeyboardDonePress); ...
// method not working: private View.OnKeyListener onSoftKeyboardDonePress=new View.OnKeyListener() { public boolean onKey(View v, int keyCode, KeyEvent event) {
if (event.getKeyCode() == KeyEvent.FLAG_EDITOR_ACTION) {
// code to hide the soft keyboard
imm = (InputMethodManager) getSystemService( Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(editText.getApplicationWindowToken(), 0); }
return false; } };
private View.OnClickListener onKeyboard=new View.OnClickListener() {
public void onClick(View v) { editText.setText(""); } };
The working method using a button (in the same java file):
private View.OnClickListener onDone=new View.OnClickListener() {
public void onClick(View v) { ....
// code to hide the soft keyboard
imm = (InputMethodManager) getSystemService( Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(editText.getApplicationWindowToken(), 0); } };
When I press key no "9" the keyboard hides.
New Swype wont let you turn off vibrate on keypress? Just downloaded the newest version, (1.56.30.7625.t100) and the setting is listed, but you cannot press it, it is "Dimmed". I am an official Beta tester, and got my version from them, through E-mail. I didn't steal the .apk
View 2 Replies View RelatedFor some reason, and only on my Dell Vostro 1000 laptop, the Android emulator keeps thinking I have the = key pressed and continually emits a string of "=====" equal signs. This happens no matter what I'm doing in the emulator. It responds to my manual keypresses as well, interspersing them. It happens no matter which version of the Android system I run (2.1, 2.2, etc.) Strangely, it happens even running the Android emulator via a remote desktop session where the remote desktop client is the laptop and the server is another PC running the emulator. If I run the emulator on the other PC locally (not remote desktop,) the emulator functions fine!
This problem didn't occur when I first installed the SDK and as far as I know no other software has been installed since then. I tried clicking the "clear user data" from the emulator launcher and still no effect. I have also tried deleting the SDK directory and reinstalling it, but the effect is still there.
Update: I found another application that exhibits this behavior. ScummVM when opening a dialog to save the game also receives these phantom keypresses. It persists in Windows 7.
By default, when in DialogPreference you press back button, it mimics that you've pressed NegativeButton. I'd like to override that but can't find an easy way except to recreate DialogPreference from scratch (which at the moment seems like an overkill), because I'd like that PositiveButton set something, NegativeButton to unset something, and back key to leave things as they were (i.e. to not unset something). I've even tried to override showDialog() but: a) its not simple, b) I don't think I should mess too much with internals of OS supplied code like a bunch of private "m" variables.
View 1 Replies View RelatedI have used a bit of Android code to override the "Done" button in my EditText field:
myEditField.setOnEditorActionListener(new TextView.OnEditorActionListener() {
@Override public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
if (actionId == EditorInfo.IME_ACTION_DONE) { mySubroutine();
return true; } return false; } } );
Activating the field calls up the keyboard, and pressing "Done" evaluates mySubroutine() successfully. However, the keyboard no longer goes away when I press "Done". How do I restore this default behavior to the routine?

View 10 Replies View RelatedSince I installed the latest upgrade 2.1 (successfully), I lost the keypress sound which was very useful. I tried the Settings/Sound and Display/Audible touch tones menu, and the Language & Keyboard/ Sound on keypress menu, in both cases I selected "on" but still I don't hear the keyboard sound which I find very useful since I am partially sighted.
View 6 Replies View RelatedIn Android I am writing an application in which, I would like to capture an event if in case user doesn't do any activity (tapping/key press). For better context - It is like session timeout.
Basic solution - I can override the key press/tapping event and put one timer which continuously run either as thread or service. In my opinion this is bit heavier solution in terms of resource.

So im just getting started with android development and i found my first head scratcher. I have an app that when opened makes a on going event notification. Then if i hit the home button the app falls from view and when i attempt to bring it back via clicking on the ongoing event notification its like opening a whole new app, then when i hit the back button the ongoing even goes away and it returns me to the original app window. How do i get the notification to take me to the original rather then opening a new instance.
