java编辑器动作监听器

Question

尝试使用以下

在edittext上使用动作列表器

editText = (EditText) findViewById(R.id.editTextnum);
    editText.setOnEditorActionListener(new OnEditorActionListener()) ;

不断收到错误“无法实例化textview的类型.OnEditorActionListner

任何想法？

                        DisplayContact(c);
                    else

你还没有实现听众。

    editText.setOnEditorActionListener(new OnEditorActionListener() {
        @Override
        public boolean onEditorAction(TextView v, int actionId,
                KeyEvent event) {
            // do things
        }
    });
