您好，我想從我的片段轉移到另一個活動。我幾乎嘗試了找到的所有解決方案，但是在按下按鈕后，我的應用程序立即關閉。我是java新手，我想我需要一些幫助。public class GalleryFragment extends Fragment { private GalleryViewModel galleryViewModel; Intent intent; public View onCreateView(@NonNull LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View rootView = inflater.inflate(R.layout.fragment_gallery, container, false); intent = new Intent(GalleryFragment.this.getActivity(), HomeFragment.class); final Button btn = (Button) rootView.findViewById(R.id.btn); btn.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { startActivity(intent); } }); galleryViewModel = ViewModelProviders.of(this).get(GalleryViewModel.class); View root = inflater.inflate(R.layout.fragment_gallery, container, false); final TextView textView = root.findViewById(R.id.text_gallery); galleryViewModel.getText().observe(this, new Observer<String>() { @Override public void onChanged(@Nullable String s) { textView.setText(s); } }); return root; }}

我從這一行假設：
intent = new Intent(GalleryFragment.this.getActivity(), HomeFragment.class);
您正在嘗試啟動Fragment，而不是Activity. 為了轉換到另一個Fragment，請將您的替換Intent為：
btn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
getFragmentManager()
.beginTransaction()
.replace(...) //Or add, depends on your use case
.commit();
}
});
