Android：在Fragment中使用Intent进行页面跳转

public class pageFragment1 extends Fragment  {
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_page_fragment1, container, false);

        TextView jr = view.findViewById(R.id.jrtj);
        jr.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Intent i = new Intent(getActivity(), test.class);
                startActivity(i);
            }
        });
        return view;
    }
}

ImageView btn1 = findViewById(R.id.btn1);
        btn1.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent i = new Intent(MainActivity.this, shouye.class);
                startActivity(i);
            }
        });
