目前我的webview类扩展了appcompatactivity,它用于扩展片段。 在我的方法我称之为片段类,如:有问题调用类扩展Appcompatactivity
@Override
public void onPostSelected(int index) {
PostData data = PostDataModel.getInstance().listData.get(index);
FragmentManager fragmentManager = getSupportFragmentManager();
PostViewFragment postViewFragment = (PostViewFragment)
getSupportFragmentManager().findFragmentByTag("postview_fragment");
if(postViewFragment == null) {
postViewFragment = PostViewFragment.newInstance(data.postLink);
} else {
postViewFragment.urlLink = data.postLink;
}
postViewFragment.title = data.postTitle;
FragmentTransaction ft = fragmentManager.beginTransaction();
ft.replace(R.id.container, postViewFragment, "postview_fragment");
ft.addToBackStack(null);
ft.commit();
}
但林不知道如何调用appcompatactivty这里扩展一个类是我的课:
public class PostViewFragment extends AppCompatActivity {
private VideoEnabledWebView webView;
private VideoEnabledWebChromeClient webChromeClient;
public String urlLink;
/**
* ATTENTION: This was auto-generated to implement the App Indexing API.
* See https://g.co/AppIndexing/AndroidStudio for more information.
*/
private GoogleApiClient client;
public static PostViewFragment Instance(String posturl) {
PostViewFragment fragment = new PostViewFragment();
/*
Bundle args = new Bundle();
args.putString(POST_URL, posturl);
fragment.setArguments(args);*/
fragment.urlLink = posturl;
return fragment;
}
}
换句话说,我不知道有什么用取代片段管理器。每次点击一个新帖子时,我需要一个新的posturl实例用于我的webview。
为什么你要调用一个扩展'Activity'的'PostViewFragment'类?这是超级混乱。如果你扩展活动,那么你的类应该被称为活动,你应该通过'Intent'将它当作活动,而不是通过'FragmentManager'。你不能用'FragmentManager'开始活动。 –
