Make EditText ReadOnly

Question

I want to make a read-only EditText view. The XML to do this code seems to be android:editable=\"false\", but I want to do this in code.

My approach to this has been creating a custom TextWatcher class as follows:

class ReadOnlyTextWatcher implements TextWatcher {
    private final EditText textEdit;
    private String originalText;
    private boolean mustUndo = true;

    public ReadOnlyTextWatcher(EditText textEdit) {
        this.textEdit = textEdit;
    }

    @Override
    public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {
        if (mustUndo) {
            originalText = charSequence.toString();
        }
    }

    @Override
    public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {

    }

    @Override
    public void afterTextChanged(Editable editable) {
        if (mustUndo) {
            mustUndo = false;
            textEdit.setText(originalText);
        } else {
            mustUndo = true;
        }
    }
}

Then you just add that watcher to any field you want to be read only despite being enabled:

editText.addTextChangedListener(new ReadOnlyTextWatcher(editText));
