How To Convert ASCII Character To Decimal Number In Android
Jul 28, 2013I'm working on an Android app. I have a TextView which contains an ASCII character. This character changes every 2 hours.

what kind of code should I use in my app to be able to convert ASCII character to decimal number?
Android :: Alarm Not Working At All On HTC Until Keypress
Dec 2, 2009My 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.

Android :: Hide Soft Keyboard On Done Keypress?
Aug 5, 2010I 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.
Motorola Droid :: Question Mark On Non ASCII Characters In Text Messages
Aug 22, 2010I have a Droid with Android 2.1. I am on a CDMA network. I send messages to some people on a GSM and when we use non-ascii characters, like ± or ¡ or Japanese and such, over sms, the other end gets them as question marks �. I don't know anybody on a CDMA network so I can not test if the problem would be there too. I don't know if it is a problem between the networks or something wrong with my phone or what. Finding information in google has proven unsuccessful. Though I found some text naming it a 'common' problem.

View 2 Replies View RelatedAndroid :: Emulator Stuck On Equals Phantom Keypress
Jul 27, 2010For 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.
Android :: Overriding Dialog Preference Default Back Keypress
Jul 7, 2010By 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 RelatedAndroid :: Hiding Keyboard In Override Done Keypress Of Edit Text
Apr 18, 2010I 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?
Android :: Way To Get Rid Of "warning : Unmappable Character For Encoding Ascii"
Apr 12, 2010I'm compiling using android tools without eclipse.
I compile launching "ant debug" from command line.
I have found many many instructions around the web about how to remove with annoying warning, but I haven't been able to make any of them work.
I've tried -D option, I've tried randomly tweaking build.* files, I've tried exporting an environment variable... nothing.
I guess some of these methods just don't work, and some others would work but I've been doing them incorrectly. Anything is possible and I can't stand it any more: any advice on how to do it?
