Android :: Show Extra Info For Preference Screens When CheckboxPreference Summary Field Is Not Enough Long?
Mar 9, 2010
I have a screen where you can enable/disable modules for my Android application.
For this I use a CheckboxPreference screen. This is all good, but the summary field gets cut off if longer descriptions are added than 2 lines.
Suppose I have 4-5 lines of description available for each module, I would like to display this in a helper window.
I tried to bind a click event to the CheckboxPreference, but that fires for the whole line, so not only when the checkbox is clicked, and more, wherever you click on the line the checkbox is toggled.
So now I am wondering if this can be fixed. So if the user needs more info, just taps the text and the helper opens up, and if want to toggle the settings it taps the checkbox.

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());
} } }

It seems Preference summary text has a limit of about 2 lines, but I want more. How can I do that?

This must come up very often. When the user is editing preferences in an Android app, I'd like them to be able to see the currently set value of the preference in the Preference summary.
Example: if I have a Preference setting for "Discard old messages" that specifies the number of days after which messages need to be cleaned up. In the PreferenceActivity I'd like the user to see:
"Discard old messages" <- title
"Clean up messages after x days" <- summary where x is the current Preference value
Extra credit: make this reusable, so I can easily apply it to all my preferences regardless of their type (so that it work with EditTextPreference, ListPreference etc. with minimal amount of coding).

Will the Droid always only have 3 screens or is there an application or upgrade that will be available soon? And second, I've heard rumors of the iPhone T-Pain app coming for android soon.

We can set the pixel values in custom views by multiplying them with
this.getResources().getDisplayMetrics().density;
This is ok when the screen aspect ratio is normal means not long
But how can we set the pixels along Y-axis when the aspect ration is long.

I am really trying to figure this out. So I go into Messaging and I'd like to type in the "to" field a contacts name, like facebook does it and it starts to list matches and then you just pick the one you want. Like it searches your contacts, but I can't figure out how to do this. Like I can only type in a number but I don't have anyones number memorized that's the point of having a saved phone book so am I missing something here?

I have encountered a problem with focused text fields in a WebView not showing entered text values.As long as a WebView text field has focus it will not show text or even the blinking cursor.You can select and highlight the text or unfocus the field to see it, but when it gains focus it will not show the text as if the foreground color of the text is white.The simplest code to demonstrate this is below.With the setTheme using a Light background, try typing values into the Email text field to notice that the text is not visible when the field is focused.

so i have gone thru everything i can find on this forum but i am at my wits end. i have been able to get my outlook contacts into my gmail account (the csv import worked reasonably well). what i don't understand is that i can view a contact in gmail and see phone numbers, address, email, etc. when i view on the G1 all i get is their email. what am i doing wrong? yes, i have gone in the "display groups" settings and tried all options. anybody else having this problem? BTW, so far i like the functionality of the starcontacts application.

I'm trying to figure out whats new but she isn't that into her phone so she never installs stuff on it, im the one tweaking and playing with her phone and I haven't touched it in a week this started happening randomly 2 days ago.

I have a lengthy (20K) text file I need to display (the terms and conditions document written by an obviously overpaid lawyer).
What's the best/simplest way to show this to a user? I loaded the text from a raw resource and added it as the message to an AlertDialog, but the text is cut off about half way. I couldn't find any obvious limits to the alert dialog text or the TextView it uses.

Just receive my Evo! My service/port is not yet activated but I am using the phone via Wifi. Why is the market slow? Searching is fine, but when I click through an app, it takes a while for the info to show up. The same is true with the install page. Just blank white boxes for a bit. Is this common?
The download page also takes quite a while to show up and it shows all the apps I've downloaded and used so far as STILL INSTALLING.

Once you fill out the submission form and upload the apk, assuming the file is signed properly, etc, how long does it take an application to show up in the Market?The Dev Guide doesn't appear to mention this detail. I'm guessing it should show up almost immediately since I've never read anything about waiting for an approval process.

I am working on learning Android programming. I am attempting to build an app that shows a list of items, and when the user clicks on an item, it will display an image of that item, as well as information about it. I'm not sure the best way to present this information. Would using the Toast widget be best? Or TextView? Or, is there another way, like creating a new activity, that makes more sense?
After the user clicks on the list item, and reads the presented info, they should be able to return to the list.

I have a TextView with its MovementMethod set to LinkMovementMethod. Text added to the TextView is a combination of normal text and URLs. For URLs, I would like to offer a context menu when the URL is long pressed for doing things such as copying the address. I've had a look at the source for LinkMovementMethod but it doesn't seem to have any long pressed related code I could override. Any ideas on how to go around achieving this?

I have all of my contacts stored as (xxx) xxx-xxxx. When I am within my own area code, I have always only dialed the last seven digits (no area code). When I do this, my Incredible doesn't recognize it as a stored contact.
I've tried storing it in different ways, xxx-xxx-xxxx, xxxxxxxxx, etc, but I do not seem to be able to make it hapen.
From what I've read, one solution is to dial the area code everytime, but who wants to do that in a local setting? Very annoying every smartphone I've ever had prior to this was able to interpret the last seven as the contact when the phone is in the default area code (and yes, mine is set to my area code).

I really liked the expose-like (Mac's expose) feature on the HTC Evo where if you pinch out it will show a spread of all your home screens as little thumbnails--like mac's expose feature. Will this be available on the Droid X?

I'm trying to learn how to do live wallpapers for android. I've got it working and now I want to add a couple preferences. So, I've created a preference activity and followed all the examples I could find.
I can capture ListBoxPreferences just fine, but the 'onSharedPreferenceChanged' method is never called when a checkbox has been changed.
Is there extra code that has to be added for capturing checkbox changes? Is there a best practices way of doing check boxes in preferences?

I would like to have a checkbox preference that takes the user to a new (sub)preference screen if the user presses on the actual text (and not on the checkbox to the right).Just as the control under Settings -> Wireless -> Mobile Network Settings -> Access Point Names.

I have a Preference that enables a sync adapter, and takes a while to actually do its work when toggled. Consequently, when the user clicks the Preference, I spin off an AsyncTask to do the work. In the meantime, I disable the Preference and replace the check box with an indeterminate ProgressBar. I have all of this working via a hack involving a subclass of CheckBoxPreference that overlays the ProgressBar on top of the CheckBox.
