Question

尝试使用此代码从适配器类启动片段

public void startFragment(Context context, int position) {
    Activity activity = (Activity) context;
    android.app.FragmentManager manager = activity.getFragmentManager();
    android.app.FragmentTransaction fragmentTransaction = manager.beginTransaction();
    DepartmentDetails departmentDetails = new DepartmentDetails();

    Bundle bundle = new Bundle();
    bundle.putString("id", departmentList.get(position).id);
    bundle.putSerializable("details", departmentList);
    departmentDetails.setArguments(bundle);

    fragmentTransaction.add(R.id.container, departmentDetails);
    fragmentTransaction.commit();
}

但它在fragmentTransaction.add(R.id.container, departmentDetails);

上标出红色

并在执行时显示

Error:(90, 28) error: no suitable method found for add(int,DepartmentDetails)
method FragmentTransaction.add(Fragment,String) is not applicable
(argument mismatch; int cannot be converted to Fragment)
method FragmentTransaction.add(int,Fragment)

这是我正在使用的片段..

public class DepartmentDetails extends Fragment implements CallBacks{

    ImageView ivProfile;
    TextView tvName, tvBasicInfo, tvDescription;
    String id, dean;
    Departments details;
    ArrayList<String> faculty, programs;

    RequestParams params;
    MyHttp myHttp;
    String url;

    public DepartmentDetails() {
        // Required empty public constructor
    }

Answer 1

您可以使用以下代码从适配器类打开片段;

  Fragment fragment = new MyFragment();
  FragmentManager fm = context.getSupportFragmentManager();
  FragmentTransaction ft = fm.beginTransaction();
  ft.replace(R.id.content_frame, fragment);
  ft.commit();

Answer 2

添加DepartmentDetails片段类

import android.support.v4.app.Fragment ;

而不是

  import  android.app.Fragment

Answer 3

请尝试使用以下代码。

  Fragment fragment = new MyFragment();
  FragmentTransaction fragmentTransaction = getSupportFragmentManager().beginTransaction();
  FragmentTransaction ft = fm.beginTransaction();
  ft.replace(R.id.content_frame, fragment);
  ft.commit();
