How do you set EditText to only accept numeric values in Android?

I ha开发者_如何学Gove 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"
