Android Solutions
Solution 1 - Android
Add android:inputType="number"
as an XML attribute.
Solution 2 - Android
For example:
<EditText
android:id="@+id/myNumber"
android:digits="0123456789."
android:inputType="numberDecimal"
/>
Solution 3 - Android
In code, you could do
ed_ins.setInputType(InputType.TYPE_CLASS_NUMBER);
Solution 4 - Android
For only digits input use android:inputType="numberPassword"
along with editText.setTransformationMethod(null);
to remove auto-hiding of the number.
OR
android:inputType="phone"
For only digits input, I feel these couple ways are better than android:inputType="number"
. The limitation of mentioning "number" as inputType is that the keyboard allows to switch over to characters and also lets other special characters be entered. "numberPassword" inputType doesn't have those issues as the keyboard only shows digits. Even "phone" inputType works as the keyboard doesnt allow you to switch over to characters. But you can still enter couple special characters like +, /, N, etc.
android:inputType="numberPassword" with editText.setTransformationMethod(null);
inputType="phone"
inputType="number"
Solution 5 - Android
android:inputType="numberDecimal"
Solution 6 - Android
<EditText
android:id="@+id/age"
android:numeric="integer"
/>
Solution 7 - Android
Try the following code:
Edittext_name.setKeyListener(DigitsKeyListener.getInstance("0123456789"));
It will allow you to enter just numbers. You cannot enter chars.
if you want to enter chars, not numbers, you can edit the values between the quotes inside getInstance
.
Solution 8 - Android
using the below can solve your problem better;
in xml:
<EditText
android:id="@+id/age"
android:inputType="numberDecimal|numberSigned" />
or //in activity inside etfield.addtextchangelistener
private String blockCharacterSet="+(/)N,*;#";//declare globally
try {
for (int i = 0; i < s.length(); i++) {
if (blockCharacterSet.contains(s.charAt(i) + "")) {
String corrected_settempvalue = arrivalsettemp.substring(0, arrivalsettemp.length() - 1);
et_ArrivalSetTemp.setText(corrected_settempvalue);
if (corrected_settempvalue.length() != 0)
et_ArrivalSetTemp.setSelection(corrected_settempvalue.length());
}
}
} catch (Exception d) {
d.printStackTrace();
}
Solution 9 - Android
If anyone want to use only number from 0 to 9 with imeOptions
enable then use below line in your EditText
> android:inputType="number|none"
This will only allow number and if you click on done/next button of keyboard your focus will move to next field.
Solution 10 - Android
You can use it in XML
<EditText
android:id="@+id/myNumber"
android:digits="123"
android:inputType="number"
/>
or,
android:inputType="numberPassword" along with editText.setTransformationMethod(null); to remove auto-hiding of the number.
or,
android:inputType="phone"
Programmatically you can use
editText.setInputType(InputType.TYPE_CLASS_NUMBER);

I need to catch pressing Enter on a keyboard with TextWatcher. But I found out that all numeric keyboards android:inputType="number" or "numberDecimal" or "numberPassword" e.t.c. don't allow me to catch Enter when user press it.
I tried android:digits="0123456789\n"
and all numeric keyboards started to work with Enter and TextWatcher.
So my way is:
android:digits="0123456789\n"
android:inputType="numberPassword"
plus editText.setTransformationMethod(null)

I don't know what the correct answer was in '13, but today it is:
myEditText.setKeyListener(DigitsKeyListener.getInstance(null, false, true)); // positive decimal numbers
You get everything, including the onscreen keyboard is a numeric keypad.
ALMOST everything. Espresso, in its infinite wisdom, lets typeText("...")
inexplicably bypass the filter and enter garbage...
Solution 13 - Android
the simplest for me
android:numeric="integer"
although this also more customize
android:digits="0123456789"
