Is there a way I can specify an input mask to the EditText control in Android?
I want be able to specify something like ### - ## - #### for a Social Security Number. This will cause any invalid input to be rejected automatically (example, I type alphabetical characters instead of numeric digits).
I realize that I can add an OnKeyListener and manually check for validity. But this is tedious and I will have to handle various edge cases.
Try using an InputFilter rather than an OnKeyListener. This means you don't have worry about tracking individual key presses and it will also handle things like pasting into a field which would be painful to handle with an OnKeyListener.
You could have a look at the source of the InputFilter implementations that come with Android to give you a starting point for writing your own.
The easiest way I know to use a mask on EditText in your Android programs in Android Studio is to use MaskedEditText library (GitHub link).
It's a kind of custom EditText with Watcher that allows you to set a hint with different color (if you want it will be available even when user already started to type), mask and it's very easy to use :-)
compile 'ru.egslava:MaskedEditText:1.0.5'
<br.com.sapereaude.maskedEditText.MaskedEditText
android:id="#+id/phone_input"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:inputType="phone"
android:typeface="monospace"
mask:allowed_chars="1234567"
mask:mask="###-##-##"
app:keep_hint="true"
/>
And that is!
You could take a look at the android.telephony.PhoneNumberFormattingTextWatcher class. It masks a phone number text input with the ###-###-#### pattern.
String phoneNumber = "1234567890";
String text = String.valueOf( android.telephony.PhoneNumberUtils.formatNumber(phoneNumber) ); //formatted: 123-456-7890
editTextMobile.setText(text); //set editText text equal to new formatted number
editTextMobile.setSelection(text.length()); //move cursor to end of editText view
Use this in an onKey function for delicious on-the-fly bunny sex with formatted phone numbers.
This site gives a good 2 classes that help with masking that I found quite useful.
You need to use the items in the comments to improve it. But worth adding to your program for ease of masking your EditText views for many masks.

I downloaded a code and the source is written in this format:
<android.support.design.widget.TextInputEditText/>
instead of:
<EditText/>
I tested both of them and i didn't see the difference, so I want to know if there's a difference between these two ways of declaring a widget in Android.
<android.support.design.widget.TextInputEditText/>
Creates a Field with an EditText with more functions like show the placeholder up the edit text when you're typing in.

Only difference is: in landscape mode you can see the hint in TextInputEditText1, whereas you can't see in EditText.
I have an EditText in my Activity that users must enter date in it in my desired format like ____/__/__. Is there any way to show this format in EditText of Android like mask textboxes of some programming languages?
Thanks,
editText.setHint("____/__/__");
OR
<EditText android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="____/__/__"/>
EDIT
I would recommend a DatePicker though rather than having users enter numbers and slashes. If DatePicker is not an option, I would then recommend 3 EditTexts that each have their own hint and which possibly automatically move between each other when they reach their automatic size.

You could do separate Edittexts with textviews of "/" between them and then concatenate them...
My EditText needs to accept input consisting of partial words, names, etc. At least on my HTC Desire, this is difficult since the keyboard wants to suggest and/or correct some entries (e.g., changes "gor" to "for"). I tried setting textNoSuggestions on the view, but that doesn't fix it.
Any simple solution to this?
Try this:
android:inputType="textFilter"
If that doesn't work, try:
android:inputType="textFilter|textNoSuggestions"
You can do this from the code. Set the input type of the EditText like below:
txtEmail = (EditText) findViewById(R.id.txtEmail);
txtEmail.setInputType(InputType.TYPE_TEXT_FLAG_NO_SUGGESTIONS);
For a list of all the available input type options see
http://developer.android.com/reference/android/text/InputType.html
The other suggestions are correct, but SwiftKey has decided it will ignore the inputtype values "in response to user requests". While I agree this is a bad idea since it contradicts the Google guidelines and developers usually have a good reason for disabling auto-correction (like username fields, family names and so on), it still is the most used keyboard application for Android devices, so this can be a big problem.
The workaround is to use either
android:inputType="textVisiblePassword"
or
.setInputType(InputType.TYPE_TEXT_VARIATION_VISIBLE_PASSWORD);
Try this if you want a multi-line EditText without displaying the underlines (auto correct):
myEditText.setInputType(InputType.TYPE_CLASS_TEXT |
InputType.TYPE_TEXT_FLAG_MULTI_LINE | InputType.TYPE_TEXT_FLAG_NO_SUGGESTIONS);
Here's XML for that: android:inputType="textNoSuggestions|textMultiLine".

I would like to know how to make a validation on EditText. For example, I have one EditText that should only accept numeric values. If something other than a numeric value is typed by the user then it should show an alert message (i.e. "please use a numeric value....").
Is there a function available to find out if the entered text is particular type? If possible please include a code snippet.
Rather than make a pop-up I would integrate a hint into the EditText and I would make it so the user could only type numbers into the EditText (android:numeric, android:hint):
<EditText android:layout_height="wrap_content"
android:numeric="integer"
android:hint="#string/numberHint"
android:gravity="left"
android:id="#+id/name"
android:layout_width="wrap_content"
android:maxWidth="60dp"
android:textSize="6pt">
</EditText>
More information is available here:
http://developer.android.com/reference/android/widget/EditText.html
Another way ,
editText.setInputType(InputType.TYPE_CLASS_NUMBER);
Please Go through My Blog post on android input validation [updated].

Which has information on,
What is regular expression
How to validate android edittext input

If you want nice looking validation messages you can use the setError method on the EditText control as I show here: http://blog.donnfelker.com/2011/11/23/android-validation-with-edittext/
The default capabilities for text/checkbox etc validation is poor within android. I have written some supporting classes to fix this. It contains a validator interface, an abstract inplementation,a validationresult class and 2 examples of custom implemented validations.
1 for regular expressions on text and a simple one to check if a checkbox is checked.
Here is the link to my blog containing the sources and a small bit of explaining
