Disabling The Send Button When The Edittext Is Empty When Using Imeoption= Actionsend

When the text is empty, we want to disable the button (which is how it's set on portrait mode) Any ideas? Edit: I don't think it's clear but I can enable/disable my own button.. Bu

Solution 1:

Add a TextChangedListener which will get called whenever the text inside the EditText gets changed.

message.addTextChangedListener(new TextWatcher() {

    publicvoidbeforeTextChanged(CharSequence s, int start, int count, int after) {}
    publicvoidonTextChanged(CharSequence s, int start, int before, int count) {}

    publicvoidafterTextChanged(Editable s) {
        if (s == null || s.length() == 0) {
           send.setEnabled(false);
           message.setImeOptions(EditorInfo.IME_FLAG_NO_ENTER_ACTION);
        }
        else {
          send.setEnabled(true);
          message.setImeOptions( /* whatever you previously had */ );
        }
}

Alternatively, you can also let your class implement the TextWatcher interface which makes the code a bit cleaner.
