[android-developers] Re: IME - Main Dictionary
Hi,
Very useful information, thanks! Got everything to work nicely, one
quick question:
I use Eclipse, not GNU make. I noticed Android.mk for LatinIME
specifies a "-0 .dict" aapt flag (I'm guessing "store uncompressed").
Is there some way to do the same while using the Eclipse builder?
Right now I'm manually fudging the generated APK (zip -d ime.apk res/
raw/main.dict; zip -0 ime.apk res/raw/main.dict) before signing, but
I'd like to do this as part of the build process (makes testing a bit
tedious).
Thanks!

[android-developers] Hardware keyboard caps state
Hi, I'm writing a Greek IME, which also needs to translate hardware keypresses. I'm doing this by intercepting onKeyDown() in InputMethodService. Is there some way to find out what the caps state is (as indicated by the plain/triangle/caret cursor in the UI for lowercase/single-caps/ all-caps, respectively), so I can accordingly output upper or lower case characters? I checked the PinyinIME code in GIT and it tries to track the hardware keyboard shift state by monitoring KEYCODE_SHIFT_LEFT and KEYCODE_SHIFT_RIGHT keypresses -- and it can get out of sync with the true state indicated by the cursor, which can be confusing. So, the question is: 1. Do I also have to track hardware shift key-down events and duplicate the caps state logic, or is there a way to query the input connection what that state is? 2. If there is no way to query the caps state, then is there a way to reset it to lowercase (since I need to know what the initial caps state is when the IME starts). Thanks!

[android-developers] Re: Should cursors used in autocomplete adapters be managed or not?
Thanks for the quick response! That's what I also thought, but then I
get these exceptions. I glanced at the Android sources, and here is
what I *think* is going on if I use managed cursors:
- Cursor returned by FilterQueryProvider#runQuery() is passed on to
SimpleQueryAdapter#changeCursor()
- changeCursor() calls close() on the *previous* cursor (which is also
managed)
- However, this is not reflected in any way in
Activity#mManagedCursors (mReleased is still false)
- If the activity is paused, then Activity#performStop() deactivates
all managed cursors and sets them to be requeried on resume
- When the activity resumes, Activity#performRestart() tries to
requery those closed cursors and the application dies
As far as I can tell, there is no hook in FilterQueryProvider (or
elsewhere), where I can call Activity#stopManagingCursor() on the old
cursor to avoid this. Also, it seems there is no way to iterate over
the managed cursors in onPause() to perform a post-mortem cleanup (no
accessor for Activity#mManagedCursors).
Or am I missing something?
Thanks,
Spiros

[android-developers] Re: Getting user's confirmation in OnPreferenceChangeListener
Ugh, nevermind -- a quick look at the Android sources solved this
easily.
For the record, this seems to be the right way to change a setting in
a preference screen:
CheckBoxPreference p = (CheckBoxPreference)findPreference
("foo_enable");
p.setChecked(false);

[android-developers] Should cursors used in autocomplete adapters be managed or not?
Hi,
I'm using an autocomplete box, with suggestions provided by a
SimpleQueryAdapter, almost identical to the code in this thread:
http://groups.google.com/group/android-developers/browse_thread/thread/8e9738ec79042f9e
Not sure if relevant, but only difference I see is that, both in the
adapter constructor, as well as in runQuery(), I use a cursor returned
by SQLiteDatabase#query() obtained via an SQLiteOpenHelper instance.
Should I be using Activity#startManagingCursor() on these cursors or
not?
If I don't use managed cursors, then I get "leak found" warnings
("database was created [sic] but never closed").
If I do then, if the application pauses (e.g., incoming call) and then
resumes, I get an unhandled exception ("attempted to requery closed
cursor" thrown by Activity#performRestart(), in Activity.java: --
SDK 1.0_r2, btw).
What am I missing?
Thanks!
Spiros

[android-developers] Getting user's confirmation in OnPreferenceChangeListener
Hi,
I have a checkbox preference which, when set for the first time, may
trigger a long-running operation. I want to get the user's explicit
consent before starting this operation. However, if the user hits
cancel, then the preference should remain unchecked.
I'm using a preference activity and register an onPreferenceChanged()
handler for the checkbox preference in question, which shows an alert
dialog (and returns true, so the preference *will* be set before the
dialog pops up).
I tried doing something like this in the AlertDialog that asks for
user confirmation, to revert that preference change if he clicks
cancel:
[]
.setNegativeButton(R.string.cancel_button, new
DialogInterface.OnClickListener() {
@Override
public void onClick (DialogInterface dialog, int which) {
Editor e = getPreferenceScreen().getEditor();
e.putBoolean("foo_enable", false);
e.commit();
SettingsActivity.this.onContentChanged();
}
})
but it doesn't quite have the desired effect: the "foo_enabled"
preference remains checked.
AFAIK there are no blocking modal dialogs in Android. Should I
perhaps be using something other than onPreferenceChanged() for this?
Any suggestions would be appreciated!
Thanks,
Spiros
