I have an EditText in which I want only integer values to be inserted. Can somebody tell me which property I have to use?
Add android:inputType="number" as an XML attribute.
For example:
<EditText
android:id="#+id/myNumber"
android:digits="0123456789."
android:inputType="numberDecimal"
/>
In code, you could do
ed_ins.setInputType(InputType.TYPE_CLASS_NUMBER);
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"
android:inputType="numberDecimal"
<EditText
android:id="#+id/age"
android:numeric="integer"
/>
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.
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();
}
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.
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)
Thanks to barmaley and abhiank.
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...
the simplest for me
android:numeric="integer"
although this also more customize
android:digits="0123456789"

I just want a numeric keypad in my android Xamarin application.
so which is better input type and why ?
from the docs
public static final int TYPE_NUMBER_FLAG_DECIMAL
Flag of TYPE_CLASS_NUMBER: the number is decimal, allowing a decimal
point to provide fractional values.
public static final int TYPE_NUMBER_FLAG_SIGNED
Flag of TYPE_CLASS_NUMBER: the number is signed, allowing a positive
or negative sign at the start.
If you want nothing but numbers allowed to be entered in your EditText` just set the digits property:
<EditText
.
.
.
android:inputType="numberDecimal|number"
android:digits="1234567890"
./>
You can also use the set the InputType as TYPE_CLASS_NUMBER
This will disable everything else but numbers good luck.
Revert in case of queries.
Solution:
If you want a keyboard only with number and without any other characters, you can do following steps:
Set your keyboard's inputType: numberPassword
<EditText
android:id="#+id/edit"
android:text=""
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:inputType="numberPassword"
/>
Then you will get a keyboard with only with numbers, however you will find numbers in EditText is invisible as security enter.
If you want to make the numbers visible in the EditText, you need to customize PasswordTransformationMethod:
private class NumericKeyBoardTransformationMethod : PasswordTransformationMethod
{
public override ICharSequence GetTransformationFormatted(ICharSequence source, View view)
{
return source;
}
}
And finally we need implementing it to the EditText in order to display the characters typed.
EditText myedit = FindViewById<EditText>(Resource.Id.edit);
myedit.TransformationMethod = new NumericKeyBoardTransformationMethod();
I find solution here and I translate it into C# code. Hope it will help you.
I am stuck in an issue where one of my user entering characters like Ä in an edittext and I am preparing an XML from that data. Due to encoding issue I can't prepare a valid XML from these kind of characters. Is there anyway I can stop user to enter such kind of characters or can I hide these characters from android default keyboard itself ?
Regards
you can restrict the user to enter only specific characters in the edit text like below,
<EditText
android:id="#+id/YourEdittextId"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:inputType="textNoSuggestions"
android:privateImeOptions="nm"
android:digits="0123456789 abcdefghijklmnopqrstuvwxyz ABCDEFGHIJKLMNOPQRSTUVWXYZ" />
Above code restrict user to enter only English digits, letters and space
Hide suggestion string in your edittext.
android:inputType="textFilter"
Few days before I was facing same issue I solved this by creating below method.
public static String stripSpecialUTFChars(String string) {
return string.replaceAll("\u0080", "");
}
Please pass your String to above method and use this like below
textView.setText(Html.fromHtml(stripSpecialUTFChars(yourString)));
actually this issue is due to UTF characters.
I want an EditText to contain exactly 8 digits (like bank accounts). Of course in addition to :
android:inputType="number"
Is there an option in XML or do I have to manage this programmatically ?
Programmatically.
Also, you can save time by using existing library EditText with validation. You can use a regex type with following pattern [0-9]{8}.
I think there is no way just in xml.
You have to validate it programmatically.
#Override
public void afterTextChanged(Editable s) {
// validation code goes here
}
This is my phone edit text:
<EditText
style="#style/ObligatoryEditTextStyle"
android:id="#+id/etxtClientPhone"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignParentLeft="true"
android:gravity="left"
android:textColor="#color/hub_blue_normal"
android:visibility="visible"
android:selectAllOnFocus="true"
android:digits="0123456789"
android:maxLength="8"/>
Tell me if I helped you and good programming!!
Try the following line in your EditText:
android:maxLength="8"
Change input type in decimal, then set maxLength="8".
android:inputType="decimal"
android:maxLength="8"
Is there any way to limit users allowed to type only some selected character set (Eg: A or B or C or D) in Android layout.xml
Use the digits attribute, only the characters passed to digits will be allowed in the EditText.
android:digits="abc123"
And yes, "digits" is a misleading name, it accepts letters and symbols too.
You can use the inputType attribute:
<EditText android:id="#+id/edit_text_id"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:inputType="number" />
Possible Values for android:inputType attribute in edit text are: none, text, textCapCharacters, textCapWords, textCapSentences, textAutoCorrect, textAutoComplete, textMultiLine, textImeMultiLine, textNoSuggestions, textUri, textEmailAddress, textEmailSubject, textShortMessage, textLongMessage, textPersonName, textPostalAddress, textPassword, textVisiblePassword, textWebEditText, textFilter, textPhonetic, textWebEmailAddress, textWebPassword, number, numberSigned, numberDecimal, numberPassword, phone, datetime, date, time
This android:digit will allow only the digits and alphabets you want to be filled in EditText.
<EditText
android:inputType="text"
android:digits="0123456789*qwertzuiopasdfghjklyxcvbnm,_,-"
android:hint="Only letters, digits, _ and - allowed"
/>
You can set your EditText Field like this...
<EditText
android:inputType="text"
android:digits="THE SELECTED CHARACTERS THAT USERS ARE ALLOWED TO TYPE"
/>
By listing the selected characters (A,B,C,and D) that users are allowed to type in the android:digits, you are limiting the possible characters that users can type. This is the easiest way I've learned through searching.
I am essentially trying to set the digits value of an EditText programmatically. So far I have:
weightInput.setInputType(InputType.TYPE_CLASS_PHONE);
weightInput.setKeyListener(DigitsKeyListener.getInstance());
Which is fine, but I also want to be able to include a decimal place (.). Any ideas?
Try this:
<EditText
android:inputType="number"
android:digits="0123456789."
/>
From Code:
weightInput.setKeyListener(DigitsKeyListener.getInstance("0123456789."));
But, it allows the user to include several "."
See JoeyRA's answer for real numbers.
Try this:
weightInput.setInputType(InputType.TYPE_NUMBER_FLAG_DECIMAL);
weightInput.setKeyListener(DigitsKeyListener.getInstance(false,true));
public static DigitsKeyListener getInstance (boolean sign, boolean decimal)
Returns a DigitsKeyListener that accepts the digits 0 through 9, plus the minus sign (only at the beginning) and/or decimal point (only one per field) if specified.
This solve the problem about the many '.' in EditText
Use InputType.TYPE_NUMBER_FLAG_DECIMAL.
Also see: Input Types.
if anyone still finding proper way, note that its setRawInputType() not setInputType()
val digits = "ABCDabcd" // or any characters you want to allow
editText.keyListener = DigitsKeyListener.getInstance(digits)
editText.setRawInputType(InputType.TYPE_TEXT_VARIATION_PERSON_NAME)
For IP address input ( Multiple dots and numbers )
try
<EditText
android:id="#+id/ipBox"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="#string/ipAddrHint"
android:inputType="numberDecimal|number"
android:digits="0123456789."
android:textSize="30sp" />
None of the above solutions worked as expected. Digits in xml file still allow me to put "," in the input.
Check for it, it's works for me:
edittext.setInputType(InputType.TYPE_CLASS_NUMBER | InputType.TYPE_NUMBER_FLAG_DECIMAL);
