Android :: After Changing A Preference - A Setting - Text Showing Settings Doesn't Update
Apr 13, 2010
I will try to explain a simple app scenario: My app goes right to a 'main view'. In this main view I have inserted a 'TextView' which displays current settings created by way of the PreferenceManager. For simplicities sake, let's say I have a checkbox in my settings. When I first start my app - the TextView on my main view shows my checkbox setting correctly (true). Now I go to the settings menu, it pops-up, and then I change it to false. I go back to the main view and...no change. It still say's true even after I changed it to false. If I end the app and then re-start it - all is well and it shows my change.
Apparently the main view just stays in the background while I'm changing settings? How can I redraw or update the main view after I change settings?

Couldn't find an answer to this...
Say I'm typing a text message and a call comes in or I go to another app or screen for some reason,(didnt send text) then come back to the messaging app the test I was typing(but didnt finish and send) is gone and I have to retype it.
Is there a setting so it doesn't delete it?
The Pre was nice because it would keep the typed unsent test till it was deleted or sent.

New to Android, I have some code when the user changes a preference I update the Summary field in the UI preference to be the value they entered. However, when the preference activity is created I'd like to set the Summary fields to be the values in the corresponding preferences.
Please advise. Thanks.
public class MyPreferenceActivity extends PreferenceActivity implements OnSharedPreferenceChangeListener { protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.preference);
SharedPreferences sp = getPreferenceScreen().getSharedPreferences();
sp.registerOnSharedPreferenceChangeListener(this);
} public void onSharedPreferenceChanged(SharedPreferences sharedPreferences, String key) { Preference pref = findPreference(key); if (pref instanceof EditTextPreference) { EditTextPreference etp = (EditTextPreference) pref; pref.setSummary(etp.getText());
} } }

Is there a way to add my IME Preferences to the "Locale&Text" menu, just like the Latin and Pinyin IME's. Or is this restricted to the keyboards that ship with the platform?

I'm not able to find any example or documentation or tutorial about how to enable or disable sync (background data and auto sync) programmaticaly, even if i can found many widget that can do that without root access or such.

I have a PreferenceActivity with a bunch of (Sub)PreferenceScreens. Each such (Sub)PreferenceScreen represents an account and has the account-username as its title.
CODE:................
As the user enters sub-PreferenceScreen, and edits the account user-name, I want the outer PreferenceScreen to update it's PreferenceScreen-title for the account in question.
I've tried to add...
CODE:.............
But the accScreen.setTitle does not seem to take effect on the outer PreferenceScreen. I've note that calling onContentChanged(); actually makes it work, but I realize that this is probably not the preferred way of doing it.
I suspect I should call postInvalidate() on some view somewhere, but I really can't figure out on what view and when to do it.
http://stackoverflow.com/questions/2396153/preferencescreen-androidsummary-update may be experiening the same problem as me.

I want to change the color of a substring while it is drawed in a text view. For example, if I have this text: "Hello this is a text in black color and (COLOR_RED_BEGIN)this is a text in red color. (COLOR_RED_END)", then when the text view draws the text the substring "this is a text in red color." must be drawn in red.

I just bought Beautiful Widgets for it's compact time/weather widget, (gained another row of icons on home screen) When you first create a widget with this, there are many configuration options, but it appears the only way to change something is to delete the old widget and create another one. Is this true, or is there a way to edit the options for an existing widget? EDIT: Found the answer in another forum. Tap the weather icon. then menu. I'd delete this, but I can't find an option to delete my post.

I'd like to check for memory leaks in my Android app using the DDMS feature in Eclipse. When I launch an emulated device, the threads display properly for the emulated device, starting with 8600 and up.
However, when I connect my Droid to the PC, the device shows up just fine in DDMS. The logcat is generated correctly, and I can view the file structure. However, threads do not display. I get "no client selected" in the Threads pane, and there is no drop-down icon next to the device listing.
Do I need to change some particular setting in Eclipse? Is this maybe a driver issue?

In my app I bring up a context menu on long click in a ListActivity. One of the options "Priority" pops up an AlertDialog with 3 radio button choices. The problem is, it displays an empty dialog box without my 3 choices, or the message that I set. Here is my code...
If I replace the .setSingleChoiceItems with a positive and negative button instead, it displays the buttons and the message as expected. What am I doing wrong in setting up my list of radio buttons? Here is my calling code as well...

I've had the Sprint EVO for about a week now and love it, except for the fact that the email settings keep changing. I go in and change the notification settings to Notification Sound "On", and then, sometimes, a few hours later, when I notice that I haven't heard any emails come in, I'll check the settings and see that Notification Sound is now "Off." Same thing with download frequency and delete email on server.

I have a TextWatcher set on an EditText that changes the input type after a user types a number followed by a space. If the user types two numbers the input type switches and accepts the next character, but if the user types only one number and presses space the input type still changes but it won't accept the first character the user tries to input. I've tested this on Froyo and 1.6, it only happens on Froyo, 1.6 works like it should.
Here's the code:................

My Droid keeps losing the setting for screen timeout. It resets to no option being selected, which means about a 5 second timeout. I have to reselect 30 seconds, etc. I can't seem to find a pattern of situation leading up to it. Started on 2.01 and continued after 2.1 upgrade. Never rooted.

Yesterday I went into my Gmail account and changed a setting, I think under the accounts/forwarding tab, and now every time I receive an Email in my Hotmail account, which is my primary one, I get duplicates. Two of every Email come in. This is rather annoying and clutters up everything, so I'm trying to figure out what setting dumbass me changed and how do I change it back.
