我已经创建了一个新的activity
,并且我使用intent
显示了它。在onCreate
我试图用我的班级替换占位符片段,但是它引发了错误 - 无法解决方法。
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_edit_viewer);
if (savedInstanceState == null) {
getFragmentManager().beginTransaction()
.add(R.id.container, new ViewerEditFragment())
.commit();
}
ViewerEditFragment类:
public class ViewerEditFragment extends Fragment {
public ViewerEditFragment() {
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.edit_viewer, container, false);
return rootView;
}
}

答案 0 :(得分:2)
由于您正在为片段扩展android.support.v4.app.Fragment,因此您需要使用getSupportFragmentManager()
而不是getFragmentManager()
。在这种情况下,请务必extend FragmentActivity
