android - EditText Values in range

Question

I would like to enter the values in a range like 1-60. The EditText shouldn't accept values like 61,62..., or 0,-1,-2...

How can we give the range 1-60 to EditText in android? I have done in main.xml as

 <EditText android:layout_height="wrap_content" 
    android:id="@+id/editText1" 
    android:layout_width="160dip" 
    android:inputType="number">
    </EditText>

You can assign a TextWatcher to your EditText and listen for text changes there, for example:

public void afterTextChanged(Editable s) {
   try {
     int val = Integer.parseInt(s.toString());
     if(val > 60) {
        s.replace(0, s.length(), "60", 0, 2);
     } else if(val < 1) {
        s.replace(0, s.length(), "1", 0, 1);
     }
   } catch (NumberFormatException ex) {
      // Do something
   }
}

As mentioned by Devunwired, notice that calls to s.replace() will call the TextWatcher again recursively.

It is typical to wrap these changes with a check on a boolean "editing" flag so the recursive calls skip over and simply return while the changes that come from within.
