Question

I have 14 edittext boxes that a user can change at will. When the text is changed in one of them, a softpad key press on the ‘enter/next/done’ key should re-run a calculation using the new text. I’ve tried onKey listener but it doesn’t work on the soft keyboard, on;y the hard keypad. I’ve tried a textwatcher like onTextChanged but it reacts and runs the calculation when only a single digit is entered, before the user can input a two or more digit number. So… I hear the onEditorActionListener works on soft keypads to watch for the keypress, but I can’t get the syntax right. Here’s what I have:

In the onCreate method:
myEdittext1.setOnEditorActionListener(this);

…
myEdittext14.setOnEditorActionListener(this);

Then, outside the onCreate method, I have:

@Override
 public boolean onEditorAction(TextView v, int actionId, KeyEvent event)
 {  if (event.getKeyCode() == KeyEvent.FLAG_EDITOR_ACTION)
    {  //do my calcs}
    }
    return(true);
 }

The code gives me the foreced-close business. Any help would be greatly appreciated.

KeyEvent can be null. You need to check for this situation in your listener.

v           The view that was clicked.
actionId    Identifier of the action. This will be either the identifier you supplied, or EditorInfo.IME_NULL if being called due to the enter key being pressed.
event       If triggered by an enter key, this is the event; otherwise, this is null.

onEditorAction is the appropriate way to listen for finish and Done soft keyboard actions.
