yourEditText.setInputType(InputType.TYPE_CLASS_NUMBER |
InputType.TYPE_NUMBER_FLAG_DECIMAL |
InputType.TYPE_NUMBER_FLAG_SIGNED);

You can use android:inputType="number"
in the XML file. You can specify other values such as numberDecimal as well.
Also, you might additionally want to use android:singleLine="true"
for a single line Edittext

and android:maxLength
. maxLength in particular can be useful for setting length limitations.

This is the final solution:
public static void enforceEditTextUseNumberOnly(EditText field) {
Typeface existingTypeface = field.getTypeface();
field.setInputType((InputType.TYPE_CLASS_NUMBER | InputType.TYPE_NUMBER_VARIATION_PASSWORD));
field.setTransformationMethod(new NumericKeyBoardTransformationMethod());
field.setTypeface(existingTypeface);
if (field.getParent().getParent() instanceof TextInputLayout) {
((TextInputLayout) field.getParent().getParent()).setPasswordVisibilityToggleEnabled(false);
}
}
private static class NumericKeyBoardTransformationMethod extends PasswordTransformationMethod {
@Override
public CharSequence getTransformation(CharSequence source, View view) {
return source;
}
}
