Android :: Java Validators Libraries To Validate Text Input From Droid App?
Sep 30, 2010
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.

I 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).

If 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.

I'm attempting to port a normal Java program over to Android, however I am having a problem with a huge number of missing Java packages (e.g., Android Java does not have java.lang.management). Is there a way for me to work around this, such as by adding the Java modules that I need?

I currently have an application using the libraries swing, swing.table, and awt on a java applet that I have running. I want to know what are the steps to get the application running as a native android app. I heard that I could use programs like Phonegap to just release a web based app for multiple platforms, but I am new to Android Programming (so far I just made a Hello Android app). I searched swing and awt, but I could not find any useful info.

I am working on a on-screen keyboard for Android, and I need to recognize starting points, turning points and end points of lines drawn by the user on the keyboard. A simple straightening function would be nice, as it is difficult to draw a perfectly straight line even with a stylus, not to mention finger-only touchscreens today.What I am trying to write is something like Swype. Any good libraries that I can use or make reference to?

As I am very pissed off of using the emulator to develop any Java class, I thought of setting up a project in Eclipse and instead of the usual JRE I linked to the Android.jar (version 2.1) that usually the Android projects link to. I don't mean to use this to develop Layouts or other specific platform things, I was just trying to create a class that uses HttpClient.
It miserably crashes like this.
CODE:.............
I mean I'd like to develop libraries (and test them) so that when I go to the emulator I don't have to deal with them. Is there a good way to do this? This seems not to work for some reason.

Does anyone know of any video encoding/decoding libraries written entirely in java? Bonus points if it works on Android. I'm trying to write a video decoding application for android, where I have access to the frame level decoding functions (which is absent in the android API MediaPlayer class)

I've been contemplating (re)building an app on iPad for some time, where I would use objective-C and DSMI to send MIDI signals to a host computer. This is not bad (I mean, except for actually writing the app).Now I'm contemplating perhaps developing the app for Android tablets (TBA).In Java, what options are available for MIDI message communication? I'm quite familiar with javax.sound.midi, but then I would need a virtual MIDI port to send messages to the host.On the other hand, if the app were done in Adobe AIR, what options would I have available for communicating with MIDI?Obviously another option is to send/receive messages over a TCP/IP socket to a Java host, and talk that way, but it sounds a tad cumbersome... or perhaps not? DSMI does use a host program, after all.

Sometimes when I type it wont fill in whatever field that I am typing in whether its a text message, search, or web page. The dictionary will come up as if I am typing the word but no actual letters will have been typed. I've tried with both the stock keyboard and better keyboard but it wont work until I restart the phone.

Regarding the lack of Predictive Text or XT9 on certain applications: I contacted google with the following bug report:- Steps to reproduce the problem. Verizon Droid Eris (stock, 1.5 i think): tap the magnifying glass to search the web. use the 9-key phone pad method of text input.
What happened."XT9" text input is locked. only "ABC" or "abc" available. What you think the correct behavior should be. All android applications and functions that accept text input should support XT9 predictive texting for the 9-key phonepad and compact-qwerty. The google folks said the following: "Android does not contain a T-9 input method by default. Please report this bug to HTC, owners of that particular piece of software."And then HTC said the following: Hello Ben Thank you for contacting HTC technical support about the abc/xt9 being greyed out. I have checked on this for you and found that is how the device is set up when using these areas on the apps. There is no way of changing this and I do apologize for that. When entering google searches and also browser addresses predictive text is not available for input. If you have any other questions feel free to reply. You may also enjoy www.htcwiki.com, our customer-based forum, which has a plethora of information on HTC devices. I would also like to invite you to participate in a customer satisfaction survey located at HTC Online Survey.

I use the phone pad style to text. ABC. Since I installed 2.1 it automatically sticks the phone on xt9. I have to toggle it to ABC before every text. Ive tried like 3 different text apps. They all do the same thing.

I am new to touch screen keyboards, and the one on this eris works me every time. I was wondering if there is any way to set default input method as t9 for texting but still have qwerty as default for all else? If not maybe someone could direct me to a better keyboard? I tried sharpnote or whatever for a couple days and actually preferred the stock keys believe it or not!

A friend of mine has a Chinese branded HTC Tattoo. That phone has a really cool input method where you can "draw" the letters on the screen. The version I have seen handles English and Chinese characters transparently without needing to switch input methods. Does anyone know if this is downloadable as an app, or what this is?

I have an AutoCompleteTextView defined as the following inside a RelativeLayout,
<AutoCompleteTextView android:id="@+id/edit_tag"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="@string/tag"
android:inputType="text"
android:imeOptions="actionNext" />
When I touch on a choice from the drop down list, instead of setting the text of this view to the one I chose, it clears the view as if no text has been inputted. I tried to debug this and walked through the execution of the program step by step. It seems to have been cleared at around line 123 in Looper.java, which I cannot see the source.

What should I do to get different input keyboards for text input in my Android. For example when I want to input text in Korean, I want a Korean KB. And if I want to do the same in Chinese, I want to get a Chinese keyboard. How do I do it programmatically?

I have an app I am working on that does some math on a few variables and outputs the answer. Well that's the plan anyway. Being a total n00b at Android & Java I am not sure of a couple of things.1) I have created text fields in the layout file for user to enter values. Instead of text fields should I use numerical value fields, if such a thing exists? 2) How can you convert from a text field to a numerical value and back again?

On some of the AVDs I've created, input text gets displayed as logograms, even in the emulated Browser application (see the screen shot at http://eduneer.com/screenshot_avd_text.png). Has anyone else experienced this or have a tip on fixing it?

I want to show edittext which will default show faint color text written as "Password". As soon as user focus on it then I want to convert it from text to password type. I did that but its not working.
On focus of the password box. I wrote as follows: Code...
Here it changes from Grey color to black. All text is also cleared. But it doesn't change to password type. Is this allowed to change dynamically input type?

I'd like to use AlertDialog as a Login or pin code or password dialog. Here is my code -
AlertDialog.Builder alert = new AlertDialog.Builder(this);
alert.setTitle("Login"); alert.setMessage("Enter Pin :");
// Set an EditText view to get user input final EditText input = new EditText(this);
alert.setView(input);
alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
String value = input.getText().toString();
Log.d( TAG, "Pin Value : " + value); return;
} } );
alert.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub return;
} } );
alert.show();
How to code that all input text will appear like ' * ' - asterisk. I can't get my pin code value although it shows into asterisk. my code is below
private void accessPinCode_2() {
LayoutInflater factory = LayoutInflater.from(this);
final View textEntryView = factory.inflate(R.layout.dialog_login, null);
AlertDialog.Builder alert = new AlertDialog.Builder(this);
alert.setTitle("Login"); alert.setMessage("Enter Pin :");
alert.setView(textEntryView);
alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
//String value = input.getText().toString();
EditText mUserText;
mUserText = (EditText) textEntryView.findViewById(R.id.txt_password);
String strPinCode = mUserText.getText().toString();
Log.d( TAG, "Pin Value : " + strPinCode); return;
} } );
alert.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub return;
} } ); alert.show(); } } dialog_login.xml
<?xml version="1.0" encoding="utf-8"?><EditText xmlns:android="http://schemas.android.com/apk/res/android"
id="@+id/txt_password"
android:password="true"
android:layout_height="wrap_content"
android:layout_width="250px"
android:layout_centerHorizontal="true"
android:layout_below="@+id/password_text"
android:singleLine="true" />
I entered the value, but get null! How to solve? Debugging is stopped at this statement. When I pointed above mUserText null value being shown in popup.
String strPinCode = mUserText.getText().toString();
I use Android 1.6. Does it depend on Version?
