Answer 1

Try:

public class CheckboxActivity extends Activity implements OnClickListener

Answer 2

You delete your onClick() first. Then change ur first line as

public class CheckboxActivity extends Activity implements OnClickListener

进口

android.view.View.OnClickListener;

之后,在您的网页上填写了right Point-> Source -> Override/Implemented Methods。

将在方言箱中自动选定浮标。蒸.和尿体的类型要求将货物输入这种方法。

Answer 3

我没有活动来源,没有工作环境来撰写法典并管理ava,因此我只是猜测。

Activity has onClick method already - make anonymous OnClickListener instance and pass it to the button (or remove inheritance from Button.OnClickListener and don t forget to call super when view is not your button). Could be also that contract has different access level in activity.
Level of language is 1.5 and you can t use annotation @override for interfaces.
