Set Edittext Digits Programmatically

Set EditText Digits Programmatically

Try this:

<EditText
    android:inputType="number"
    android:digits="0123456789."
/>

From Code:

weightInput.setKeyListener(DigitsKeyListener.getInstance("0123456789."));

But, it allows the user to include several "."

        if (!Character.isLetter(source.charAt(i))&&!Character.isSpaceChar(source.charAt(i))) {
            return "";
        }
    }
    return null;
}
};
edit.setFilters(new InputFilter[] { filter });

Ther have two ways for your question
1) in your XML fayl

  android:id="@+id/edittext"
  android:layout_width="match_parent"
  android:layout_height="wrap_content"
  android:digits="123456789"
  android:inputType="number"
  android:maxLength="1"/>

2) in your Activity class

    mEdit.setInputType(InputType.TYPE_CLASS_NUMBER );
    mEdit.setKeyListener(DigitsKeyListener.getInstance("0123456789"));
    mEdit.setSingleLine(true);

How to set InputType 'time' programmatically?

For time field:

You should try with

setKeyListener(DigitsKeyListener.getInstance("0123456789:"));
