Java 我在实现addTextChangedListener时出错，如何修复它？

我创建了一个

EditText

，并将其设置为addtextchangedlistener。 代码是：

 shared_tags.addTextChangedListener(new TextWatcher() {


    @Override
    public void onTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) {
        // TODO Auto-generated method stub
        shared_tags.setText( shared_tags.getText().toString().toLowerCase().replace(" ", "#"));
    }

    @Override
    public void beforeTextChanged(CharSequence arg0, int arg1, int arg2,
            int arg3) {
        // TODO Auto-generated method stub

    }

    @Override
    public void afterTextChanged(Editable arg0) {
        // TODO Auto-generated method stub

    }
});

但它给出的误差如下：

03-13 23:22:03.384: E/InputEventReceiver(19895): Exception dispatching input event.
