안드로이드 자바에서 Fragment에서 새로운 activity 창을 열고 싶은데 버튼을 누르면 앱이 오류와 동시에 종료가 됩니다..

f0Binding.ibBk.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { startActivity(new Intent(getContext(), Bk.class)); } }

ibBk이라는 버튼을 누르면 새로운 창이 뜨게 하고 싶은데 방법이 있을까요??

package com.example.up;

import androidx.annotation.NonNull; import androidx.annotation.Nullable; import androidx.fragment.app.Fragment;

import android.content.Intent; import android.os.Bundle; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.Button;

import com.example.up.databinding.ActivityFrag0Binding; import com.example.up.databinding.ActivityMainBinding;

public class Frag0 extends Fragment {

private ActivityFrag0Binding f0Binding; // 프래그먼트 바인딩
private View view;
private ActivityMainBinding mainBinding; // 메인
private Frag0 frag0;
private Frag1 frag1;
private Frag2 frag2;
private Button ib_bk;



@Nullable
@Override
public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { //프래그먼트는 onCreateView로 시작한다 #25 14:16
    f0Binding = ActivityFrag0Binding.inflate(inflater,container,false);
    view = inflater.inflate(R.layout.activity_frag0,container,false);


    f0Binding.ibBk.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            startActivity(new Intent(getContext(), Bk.class));


          Intent intent = new Intent(getActivity(), bk.class);
            startActivity(intent);


        }

    });

    return view;
}

}
