Try the following code:
<pre><code>Edittext_name.setKeyListener(DigitsKeyListener.getInstance(&quot;0123456789&quot;));

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 <code>getInstance</code>.

using the below can solve your problem better;

in xml:

<pre><code>&lt;EditText
 android:id="@+id/age"
 android:inputType="numberDecimal|numberSigned" /&gt;
</code></pre>

or //in activity inside etfield.addtextchangelistener

<pre><code> private String blockCharacterSet="+(/)N,*;#";//declare globally
 try {
 for (int i = 0; i &lt; 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) {

You can use it in XML

<pre><code>&lt;EditText
 android:id="@+id/myNumber"
 android:digits="123"
 android:inputType="number"

or,

<pre><code>android:inputType="numberPassword" along with editText.setTransformationMethod(null); to remove auto-hiding of the number.

<pre><code>android:inputType="phone"

Programmatically you can use 
 editText.setInputType(InputType.TYPE_CLASS_NUMBER);

I need to catch pressing Enter on a keyboard with <a href="https://developer.android.com/reference/android/text/TextWatcher" rel="nofollow noreferrer">TextWatcher</a>. 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 <code>android:digits="0123456789\n"</code> and all numeric keyboards started to work with Enter and TextWatcher.

So my way is:

<pre><code>android:digits="0123456789\n"
android:inputType="numberPassword"
</code></pre>

plus <code>editText.setTransformationMethod(null)</code>

Thanks to barmaley and abhiank.

blocks|key|1042428|text|我不知道13年的正确答案是什么，但今天是：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1042429|myEditText.setKeyListener(DigitsKeyListener.getInstance(null,+false,+true));++//++positive+decimal+numbers|offset|length|style|CODE|1042430|你得到了一切，包括屏幕上的键盘是一个数字键盘。|1042431|几乎所有的东西。Espresso，以其无限的智慧，让typeText("...")莫名其妙地绕过过滤器，进入垃圾...|1042432|entityMap^0|0|0|2Y|0|0|Q|F|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|O|8|@$D|P|E|Q|F|G]]|9|@]|A|$]]|$1|H|3|I|5|6|7|R|8|@]|9|@]|A|$]]|$1|J|3|K|5|6|7|S|8|@$D|T|E|U|F|G]]|9|@]|A|$]]|$1|L|3|-4|5|6|7|V|8|@]|9|@]|A|$]]]|M|$]]

I don't know what the correct answer was in '13, but today it is: 

<code>myEditText.setKeyListener(DigitsKeyListener.getInstance(null, false, true)); // positive decimal numbers</code>

You get everything, including the onscreen keyboard is a numeric keypad.

ALMOST everything. Espresso, in its infinite wisdom, lets <code>typeText("...")</code> inexplicably bypass the filter and enter garbage...

the simplest for me

<pre><code>android:numeric="integer"

although this also more customize

<pre><code>android:digits="0123456789"

I have an <code>EditText</code> in which I want only integer values to be inserted. Can somebody tell me which property I have to use?

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

我有一个EditText，我只想在其中插入整数值。有人能告诉我我必须使用哪个属性吗？
