Is there a way in android to invoke a numeric only keypad, i.e. a virtual keypad that contains only the numbers 0 to 9 and a "." sign?
Try doing android:inputType="phone" ?
Basically, you need what Peter Boughton said.
More generally, if you need to invoke different type of keyboard, depending on the input you expect on your EditText component, you should use the IMF (Input Media Framework) and different IMEs (Input Media Editors).
You can customize not only the input symbols, but also the layout of the keyboard in your application, auto-completion and other options.

Updating Applications for On-screen Input Methods
If you're talking about restricting input to 0-9 + "." for an EditText box, I use the android:numeric="decimal" attribute in the layout XML.
<EditText android:numeric="decimal" />
If you're working with dynamically generated EditText views, the relevant method to call on it is
setKeyListener()
Make sure you only have:
<EditText android:numeric="decimal" />
and not both:
<EditText android:numeric="decimal"
android:digits="0123456789." />
The latter, ie using both numeric and digits was not working for me. However, using only numeric works.
<EditText android:numeric="decimal" />
only does not affect keypad to convert into decimal.
Instead, use:
<EditText android:inputType="phone" android:numeric="decimal"></EditText>
This will show the numeric keypad only.

I am trying to make an EditText such that, when I click it, a keyboard containing ".com" appears, because a URL is to be entered into the EditText.
I tried to use this:
android:inputType="textUri"
but it is not working. How do I do it?
try this one
<EditText
android:id="#+id/edt"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:inputType="textWebEmailAddress"
/>
android:inputType="textWebEmailAddress"
use this property for that.
You can use inputType as textWebEmailAddress or textEmailAddress. Specs say it is device dependent but honestly I did not find any difference. Purpose of using this is you can use the # and .com keys in the keypad. I tried both on samsung Galaxy S5 and keypad is the same.
I created two EditText with these two property.
android:digits="0123456789"
android:inputType="numberDecimal"
I use Hardware Keyboard, when I perform Enter Key, focus control not shifting from one view to next view, as it happen normal in EditText case. If I remove "android:digits" property then it work properly, but here it allow to insert decimal key also, that I don't want.
I tried with "android:nextFocusDown" proerty also, but that is also not working in this case.
Any one have idea how can use Enter key event to shift focus.
use
Either
android:inputType="number"
or
android:digits="0123456789"
PS :
best one is android:inputType="number" because it will automatically open the numeric keyboard
where as android:digits="0123456789" this will open simple keyboard
Add this to the layout:
android:singleLine="true"
You don't need android:inputType="numberDecimal", since you declared only digits in the android:digits="0123456789"
I am looking to implement both phone pad and keypad in Android.As, per my requirement when the EditText is selected a default phone pad should be shown. But the user must be able to input alphabets also. Please suggest me a way to implement this.
<EditText
android:id="#+id/editTextref1"
android:layout_width="210dp"
android:layout_height="45dp"
android:layout_alignParentRight="true"
android:layout_marginTop="10dp"
android:ellipsize="start"
android:hint="#string/custom1"
android:imeOptions="actionNext|actionDone"
android:inputType="text"
android:nextFocusDown="#+id/editTextref2"
android:shadowDy="10"
android:textColor="#383838"
android:textSize="14sp"
android:textStyle="bold"
android:maxLength="15"
android:typeface="serif" />
I would like to make an assumption that it's impossible to do that in a simple and elegant way. The problem is that you input type is InputType.TYPE_CLASS_TEXT and it cannot be changed to InputType.TYPE_CLASS_NUMBER because you need to input letters as well.
The problem is that input method checks the type of input and gives you the appropriate keyboard with numbers or alphabet depending on the type of the field input type. If you ask input method to give you number keyboard and you have your EditText in focus, you cannot force the input method to switch to alphabet keyboard in your code. I may be wrong but this is what I think.
The question is whether you can ask any third party input method to give you different keyboard while editing text - I think you cannot do this in your code. Input method will give you numbers or alphabet depending on your EditText but you cannot switch them dynamically because input method is not aware of your design issues. The only way you can do this is to make your own input method that allows you to switch numeric and alphabet keyboards dynamically.
Let's say I have an EditText and I want to restrict it to 0-9 and A-F (inclusive), for hex input. Is there a way I can do that? I tried looking at InputFilters and I'm not sure that's the right way. Has anyone achieved this?
Set the input type to number and digits to "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ"
In an xml file it would look like this:
<EditText
android:id="#+id/hexedit"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:digits="0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ"
android:inputType="number"
/>
You can experiment with different inputTypes to see which soft keyboard layout they bring up.
How can I validate a text view in android to handle positive integer numbers?
I don't want it to accept any character or signs etc...
Have you taken a look at the EditText's inputType attribute? You can set a whole bunch of different input types that the EditText should limit the user input to.
From the sounds of it, you're probably looking for something like:
<EditText
....
android:inputType="number"
... />
You can use regular expressions. See:
http://developer.android.com/reference/java/util/regex/Pattern.html
Your pattern could look like ^[0-9]{1,10}$
which means that the entered value can only consist of digits (minimum 1, maximum 10)
IMO best way is use inputType in xml
<EditText
...
android:inputType="phone" />
You have to remember that "+" is also part of the phone number.
Use the code in your Edittext XML to restrict any range of values
android:digits="0123456789"
You can use from XML
<EditText
...
android:inputType="phone" />
or programmatically
EditText editText = (EditText) findViewById(R.id.yourId);
editText.setInputType(InputType.TYPE_CLASS_NUMBER);
