To do it in a Java file:

<pre><code>EditText input = new EditText(this);
input.setInputType(InputType.TYPE_CLASS_NUMBER);
</code></pre>

blocks|key|1505926|text|我发现这个实现很有用，显示了更好的键盘并限制了输入字符。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1505927|<EditText

I found this implementation useful, shows a better keyboard and limits input chars.

<pre><code>&lt;EditText
 android:inputType="phone"
 android:digits="1234567890"
 ...
/&gt;
</code></pre>

Additionally, you could use <code>android:maxLength</code> to limit the max amount of numbers. 

To do this programmatically:

<pre><code>editText.setInputType(InputType.TYPE_CLASS_PHONE);

KeyListener keyListener = DigitsKeyListener.getInstance("1234567890");
editText.setKeyListener(keyListener);
</code></pre>

will show the large number pad as dialer.

blocks|key|1291516|text|如果你需要小数，那么这就是你的答案：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1291517|android:inputType="numberDecimal"|code-block|syntax|javascript|1291518|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

If you need fractional number, then this is the answer for you:

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

If you are using your EditText in Dialog or creating dynamically and You can't set it from xml then this example will help you in setting that type of key board while you are using dynamic Edit Text etc

<pre><code>myEditTxt.setInputType(InputType.TYPE_CLASS_NUMBER);
</code></pre>

where myEditTxt is the dynamic EDIT TEXT object(name)

Below code will only allow numbers "0123456789”, even if you accidentally type other than "0123456789”, edit text will not accept.

<pre><code> EditText number1 = (EditText) layout.findViewById(R.id.edittext); 
 number1.setInputType(InputType.TYPE_CLASS_NUMBER|InputType.TYPE_CLASS_PHONE);
 number1.setKeyListener(DigitsKeyListener.getInstance("0123456789”));

<pre><code>EditText number1 = (EditText) layout.findViewById(R.id.edittext); 
number1.setInputType(InputType.TYPE_CLASS_NUMBER);
</code></pre>

I just basically want to switch to the number pad mode as soon a certain EditText has the focus.

How do I show the number keyboard on an EditText in android?

我只是想在某个EditText获得焦点后立即切换到数字键盘模式。
