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

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

<EditText
    android:inputType="phone"
    android:digits="1234567890"
    ...
/>

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

To do this programmatically:

editText.setInputType(InputType.TYPE_CLASS_PHONE);

KeyListener keyListener = DigitsKeyListener.getInstance("1234567890");
editText.setKeyListener(keyListener);

You can configure an inputType for your EditText:

<EditText android:inputType="number" ... />

To do it in a Java file:

EditText input = new EditText(this);
input.setInputType(InputType.TYPE_CLASS_NUMBER);
