java - 从 fragment 调用 Intent

Question

我有一个 fragment

public class TwitterFragment extends Fragment implements OnClickListener {}

从这个 fragment 我调用了一个 Intent :

Intent intent = new Intent(this, WebViewActivity.class);

在哪里，

public class WebViewActivity extends Activity {

但是调用 Intent 会出错:

Error:(214, 33) error: no suitable constructor found for Intent(TwitterFragment,Class<WebViewActivity>)
constructor Intent.Intent(String,Uri) is not applicable
(argument mismatch; TwitterFragment cannot be converted to String)
constructor Intent.Intent(Context,Class<?>) is not applicable
(argument mismatch; TwitterFragment cannot be converted to Context)

当 TwitterFragment 类扩展 Activity 而不是 fragment 时，此代码有效。

Answer 1

Fragment 不是 Context。试试这个:

Intent intent = new Intent(getActivity(), WebViewActivity.class);
