B4A Library AHPreferenceActivity Library

corwin42 · Nov 18, 2011

This Library is based on Erels PreferenceActivity Library and adds some hopefully useful things:

Checkbox entry can show On and Off summary
Dependencies to other entries
Another Listview type with Map as value/displayvalue pairs
AddPassword() for password entries
AddRingtone() for selecting notification, ringtone or alert sound

V1.01:

Bugfix for FC with nested PreferencesScreens
Added support for calling Intents (other activities)
Preferencescreens support dependency

V1.02:

Bugfix for GetUpdatedKeys not working sometimes (thanks, Erel)

V1.03:

Never published

V1.04:

Added AddEditText2() method with support for InputType and some other properties
!!! Changed package name to "de.amberhome.objects" !!! Change in your Manifest!

For a tutorial see PreferenceActivity Tutorial

Hi,
I'm using the AddList2 method to show a set of choices. Is there any way to show the selected choice as the subtitle on the settings screen after selection?
Thanks
Andrew

No, currently not.

HI, no plans to add a user picture selection ?

Hi,
Is there any way to trigger an event when a user either clicks on a certain setting, or when a setting changes? I'd like to trigger some onward processing, but I'd prefer not to have to create a dummy intent with all that entails. One of Erel's posts suggested that this library provides some change events, but I can't see how this works.

Thanks
Andrew

No, events are not possible.

See the changelog in first post. The package name was changed to prevent conflicts with other libraries. You have to change it in the manifest of your project, too.

Thanks for the reply , infact i didn't change it at firs but when i run the app it showed an exception when trying to get into the preference screen and after i saw it i changed the package name and i got into the preference without any errors except the setActivity was not working

so i should have wrote in the first post that i changed the package name lol sorry

Hello!!

I use the AHPreference-lib to set some passwords. But I have seen, that the dictionary saves the passwords, even though I used 'addpassword'.
I know, that it is possible to prevent this with the following code. Is it possible to combine this with the password-mode of the perference?

B4X:

PasswortFTP.InputType=Bit.OR(PasswortFTP.InputType,0x00000080)

Thanks for help...

schimanski · Jun 14, 2014

O.k, I have found a way with the SLInpTypeConst-Class:

B4X:

Dim InpTyp As SLInpTypeConst
InpTyp.Initialize
Cat_FTP.AddEditText2("PasswortFTP", "Passwort", "Passwort für FTP-Zugang eingeben", "", InpTyp.TYPE_NUMBER_VARIATION_PASSWORD, True, False, "")

Greetings....

Hey, my app crashes when I open the AHPreferenceActivity while the device is in landscape mode, is this a common problem? Is there a fix available?

Works without problem here.

Do you have a stack trace?

Probably not since I don't know what that is

The complete error message and a logcat snippet from the error.

No one can guess what "my app crashes" means.

No actual error message pops up on my phone, only that the app has stopped working.

http://i.gyazo.com/02ca72891bf12dac7d2934658c452aeb.png

First line is

B4X:

java.lang.RuntimeException: Unable to start activity ComponentInfo{b4a.example/de.amberhome.objects.preferenceactivity}: java.lang.NullPointerException: Attempt to invoke virtual method 'java.util.Iterator java.util.ArrayList.iterator()' on a null object reference

Also, what is the Dependency when creating views in a PreferenceScreen and what should I have there?

Sorry, these are probably all stupid questions, I'm new :/

Do you have the preference activity declared in the manifest editor? You have to add

B4X:

AddApplicationText(<activity android:name="de.amberhome.objects.preferenceactivity"/>)

there.

With the dependency you can make dependent settings. So when you uncheck a checkbox setting all dependent settings will be grayed out. I think the usage is in the example. If you don't need this feature just enter an empty string as parameter.

I already have both of those. The crash only happens in landscape mode. When my phone is in portrait mode, I have no problem opening the settings screen :/
