Need number only soft keyboard?

Question

Hi I need a soft keyboard with only numeric values 0 to 9 and Enter key. Shouldn't show anything other than these like . , ( ) etc...

I tried several options as suggested here but nothings seems to work for me.

1. setRawInputType(Configuration.KEYBOARD_QWERTY)
2. setRawInputType(InputType.TYPE_CLASS_NUMBER | InputType.TYPE_NUMBER_FLAG_SIGNED)
3. setRawInputType(InputType.TYPE_CLASS_NUMBER)
4. setRawInputType(InputType.TYPE_CLASS_PHONE)

I always have the extra characters show up on the keyboard like:

setRawInputType(Configuration.KEYBOARD_12KEY) shows a keyboard like this:

Would appreciate any help. Thanks in advance.

Answer 1

By default based on your device, the keyboard shows the special characters too in number keyboard . specifying the Keyboard type for the Text field you can achieve the expected result,such as

 InputFieldName.setInputType(InputType.TYPE_CLASS_NUMBER | InputType.TYPE_NUMBER_VARIATION_PASSWORD);

i.e.

If you need only number included with special characters,then you can use InputType.TYPE_CLASS_NUMBER

or

if you need to exclude those special characters too then use InputType.TYPE_NUMBER_VARIATION_PASSWORD

This solution uses numberPassword by overriding the default transformation method for the EditText to show characters instead of dots.

<EditText
    android:id="@+id/userid"
    android:inputType="numberPassword"
    android:maxLength="6"
/>

Add to OnCreate.

// Numeric 6 character user id
EditText input = findViewById(R.id.userid);

// Process input and show characters instead of dots
input.setTransformationMethod(SingleLineTransformationMethod.getInstance());
