Live Character Count For EditText Android

Question

Hello,

I was wondering what the best way to do a live character count of an edit-text box is in Android. I was looking at this but I couldn't seem to make any sense of it.

To describe the problem, I have an EditText and I'm trying to limit the characters to 150. I can do this with an input filter, however I want to show right below the text box the number of characters a user has entered(Almost like stack overflow is doing right now).

If someone could write a small snippet of example code or point me in the right direction I'd appreciate it a lot.

Thanks in advance.

Try doing something like this:

  EditText et;
  et.setOnEditorActionListener(new OnEditorActionListener() {

    @Override
    public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
      /* Do something interesting with the length */
      v.getText().length();
      return false;
    }
  });

setOnEditorActionListener

Set a special listener to be called when an action is performed on the text view. This will be called when the enter key is pressed, or when an action supplied to the IME is selected by the user.
