我有一个显示使用的Dialog片段。顺便说一下，我更新了我的支持库，包括材料设计主题和新类。是否有可能新的fragmentDialog片段是错误的
fragment.show(getSupportedFragmentManager(),null);
这是片段的代码
public class NewTimedEvent extends DialogFragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
return inflater.inflate(R.layout.fragment_new_timed_event, container, false);
}
@Override // show User interface in a dialog
public Dialog onCreateDialog(Bundle savedInstanceState) {
// Use the Builder class for convenient dialog construction
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
LayoutInflater inflater = getActivity().getLayoutInflater();
View view = inflater.inflate(R.layout.fragment_new_timed_event, null);
builder.setView(view);
builder.setPositiveButton(getString(android.R.string.ok), new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
}
});
builder.setNegativeButton(getString(android.R.string.cancel), new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
}
});
// Create the AlertDialog object and return it
return builder.create();
}
}
这里的错误是获取
