Question

这是活动类中的onclick项侦听器，其中传递了名为movieTagsItem的对象

public void onItemClick(MovieTagsItem movieTagsItem) {
        Log.d(TAG,"It is clicked");
        FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
        ft.replace(R.id.news_details, MovieProfile2.newInstanceFromMovieTags(movieTagsItem));
        ft.commit();

    }

这是我的片段类，其中调用和执行对象。问题是我无法在onCreatView

中定义布局

public class MovieProfile2 extends Fragment {
    private static final String TAG = MovieProfile2.class.getSimpleName();

    MovieProfile movieInfo;

    public static MovieProfile2 newInstanceFromMovieTags(MovieTagsItem movieTagsItem) {



        Bundle args = new Bundle();
        args.putSerializable("movieTag", movieTagsItem);
        MovieProfile2 fragment = new MovieProfile2();
        fragment.setArguments(args);
        return fragment;
    }


    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        final View view = inflater.inflate(R.layout.layout_movie_profile2, container,false);
        Log.d(TAG, "layout is working: "+ inflater.inflate(R.layout.layout_movie_profile2, container,false));



        MovieTagsItem movieTagsItem = (MovieTagsItem)getArguments().getSerializable("movieTag");
        Log.d(TAG, "Movie Id: "+ movieTagsItem.getMovieId());

          int id = movieTagsItem.getMovieId();

return view;
}

}

这是我的片段布局，它应该在从活动类执行onclick操作后膨胀，其中需要数据即将到来，但布局没有显示

Answer 1

您正在尝试替换 news_details 片段，但在您的片段XML中，没有任何内容与 layout_movie_profile2 的ID相匹配

Answer 2

在联系人ID中定义xml文件中将此传递ID转换为news_details，如下面的代码..

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/content_main"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior"
tools:context=".activities.MainActivity"
tools:showIn="@layout/app_bar_main">


</FrameLayout>

然后将id定义为替换片段..

 ft.replace(R.id.content_main, MovieProfile2.newInstanceFromMovieTags(movieTagsItem)).addToBackStack(null).commit();

布局在活动交易后不会在片段中膨胀
