Question

First, I don’t know what’s the key code for the Return key or Backspace the one that has a line on the Android keyboard.

Secondly I have multiple edittext fields on the screen and I want each one to resign the keyboard when the user hit that Return key.

    imm= (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);

   public void onClick(View v) {
     int flag;
     flag=v.getId();
     // keycode for return
     if(v.getId()==XX) {
         imm.hideSoftInputFromWindow(YYY.getWindowToken(), 0);

     }

XX is the keycode for that Return key and YYY is what I should fill in. I would like YYY generic that’s applying to all the edittext fields in the program

I’m not sure why you are trying to handle this in an onClick method. The right way, I think, is to call setOnKeyListener() for each EditText view and in your OnKeyListener, you can do this:

public boolean onKey(View v, int keyCode, KeyEvent event) {
    if (keyCode = KeyEvent.KEYCODE_ENTER) {
        // non-null only for enter key
        imm.hideSoftInputFromWindow(v.getWindowToken(), 0);
        return true;
    }
    return false;
}

A single instance of OnKeyListener can be used for all EditText views (any view at all, actually) where you want this behavior.
