Does anyone have sample code to validate user entered text in preferences? For example, I have a EditTextPreference for user to enter an email address. I'd like to validate the format of email address entered and pop up an alert dialog if the format isn't correct. Anyone have any sample code for this?

View 1 Replies View RelatedI have a shared preference that is being accesed via an EditTextPreference. I am in the process of porting this application to a device that does not have a hardware keyboard for text entry. When the time comes to modify the EditTextPreference, there is no soft keyboard that becomes available, and I am at a loss as to how to invoke the soft keyboard for text input to edit this preference.
View 1 Replies View RelatedI would like to use EditTextPreference to show 2 input fields instead of 1. For instance, a username and password field should be shown. I don't want to use a dialog for each one. How can this be done? In the WiFi settings there is one that does this, when you want connect to a protected network, a dialog shows to set a password for the credential storage with 2 fields.
View 1 Replies View RelatedI have a Preferences dialog with some EditTextPreference elements. The preference values can be edited by end-users when they click on the particular item. However, at the first application launch, I would like to create a sort of wizard to guide the end-users through the configuration. I need to show the EditTextPreference edit dialog programatically. Somehow I need to emulate the end-user clicked on the preference.
Is it possible?
Two activities here, A and B. A is main, B is PreferenceActivity with two EditTextPreference.
I want to be able to access the preferences generated by B from activity A, and for that I need of course (I guess) getSharedPreferences on A. But in order to do that I need to supply the preference file for the activity that generated it. This is tedious (long names), erratic at best (depends on the activity that generated it), and finally it's a mess, because it's much better to keep everything under one xml file, with a name that is well known to all my activities. And besides, if I have 100 activities, how would I keep track of preference files anyway...
So the point is: how do I "bind" an EditTextPreference in a way that the changes are made to a given preference file, not the one automatically generated by Android?
The preference activity gets inflated by invoking
addPreferencesFromResource(R.xml.preferences);
and here are the preferences.xml code...
everything looks okay, but EditTextPreference entries (2 and 3) have arrow-down icons next to them, just like ListPreference (1) does. Why is it so and how can I remove these icons as they look irrelevant?

View 2 Replies View RelatedI'm an android developer trying to use the javax.crypto package to encrypt/decrypt my SQLite database backups when I put them on the SD Card.That way, they can't be read while they're in the publicly accessible file system.I can encrypt/decrypt the file just fine, but I have no idea how to tell if the user input the right key or the wrong key. An incorrect key just returns a more jumbled file. I need a way of validating the user's password without storing it on the device (since they could be importing to another device).How can I check to see if the file has been successfully and correctly decrypted?
View 1 Replies View RelatedI need to do form input validation on a series of EditTexts. I'm using OnFocusChangeListeners to trigger the validation after the user types into each one, but this doesn't behave as desired for the last EditText. If I click on the "Done" button while typing into the final EditText then the InputMethod is disconnected, but technically focus is never lost on the EditText (and so validation never occurs).

View 3 Replies View RelatedIf I want to enforce a maximum length of input in an EditText field, I can use the maxLength attribute. But if I want to enforce a minimum length (in my case, simply non-blank), I find no corresponding minLength attribute. I've also looked at the various 'inputType' attributes (phone, password, etc) but I don't see anything like 'required' or 'non-blank'. I can't believe this would require a custom input filter; it's more likely the answer is so obvious it just doesn't get written down in the form I'm asking the question.

Is there any Java validator libraries i can use to validate text input from an android app?
i know that in spring there are validators for various different types such as checking if a value is a int, if a value is a valid email, etc etc.
Anything similar in core Java or even android?
cheers in advance. i don't want to re-invent the wheel if its already been implemented. i could always sue Java reg expressions to construct my own ones but was wondering if their was one done specifically for email formats.
