preferenceactivity

I want to change the look of my Android app's preference screen to dark text color. How can I do this? (I´ve already changed the background to white color) I assume you use an Activity which extends the PreferenceActivity . You can use the setTheme method to set a custom theme on your preference screen. Just define one in res/values/themes.xml . It would look like this: <?xml version="1.0" encoding="UTF-8"?> <resources xmlns:android="http://schemas.android.com/apk/res/android"> <style name="Theme.DarkText"> <item name="android:textColor">#000000</item> </style> </resources> Afterwards set it

I added preference-headers to my app so that the preference screen would not look broken on Honeycomb and tablet sized ICS. However, I only have one header at the moment so you have to click through a header screen with only one entry on phone sized devices. Is there an easy way to tell android to skip the header screen when there's only one header, but to still show it on large screens? It seems that the stock Contacts app does this successfully but I've browsed through its source and can't figure out how it is doing it. jenzz You can skip the headers by setting one of your

Is there a way to dynamically show and hide preferences? In my case, I have a checkbox preference that would disable or enable one of 2 preference groups ("with-" and "without-handicap" groups). While this would be the ideal GUI in a desktop environment, the "with-handicap" takes up nearly the whole screen, while the other, "without-handicap" takes up only a small portion of the screen. Rather than showing both groups at the same time, I'd like to show only one of them at a time, and dynamically show or hide the 2 groups when the checkbox changes. Is there a way to do this? dhaag23 From a

I am building a Preference Activity where most of the preferences in the list will be executing code and not modifying a SharedPreference directly. My preferences.xml file looks like this. <PreferenceCategory android:title="Connection" > <Preference android:id="@+id/settings_connectToNewComputer" android:key="connectToNewComputer" android:summary="Currently connected to:" android:title="Connect to new computer" /> <Preference android:id="@+id/removeDevice" android:key="removeDevice" android:summary="Remove this device from the computer's whitelist" android:title="Remove this device from

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. PreferenceScreen root = mgr.createPreferenceScreen(this); for (MyAccountClass account : myAccounts) { final PreferenceScreen accScreen = mgr.createPreferenceScreen(this); accScreen.setTitle(account.getUsername()); // add Preferences to the accScreen // (for instance a "change username"-preference) ... root.add(accScreen); } As the user enters sub-PreferenceScreen, and edits the account user-name, I want the outer PreferenceScreen

Based on the following code, can you tell me how to refresh the PreferenceActivity window to show changes in the settings immediately? For example: the user taps the master chime toggle checkbox to true (ticked), I would like the user to immediately see the other settings such as the ChimeOn15Past checkbox also be be true (ticked) SharedPreferences.Editor prefEditor = clockSettings.edit(); // Allow the settings to be changed. if (booleanMasterChimeToggle == true) { prefEditor.putBoolean("ChimeOnTheHour", true); prefEditor.putBoolean("ChimeOn15Past", true); prefEditor.putBoolean("ChimeOn30Past"

My PreferenceActivity looks like: import android.os.Build; import android.os.Bundle; import android.preference.PreferenceActivity; import android.preference.PreferenceFragment; import android.widget.TextView; public class Settings extends PreferenceActivity { @SuppressWarnings("deprecation") @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); //setContentView(R.layout.about); Typeface timesFont = Typeface.createFromAsset(getAssets(), "fonts/times.ttf"); TextView about_txt = (TextView) findViewById(R.id.about_txt); about_txt.setTypeface(timesFont);
