試試這個...
public class select_fragment extends Fragment {
@Nullable
@Override
public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup
container, @Nullable Bundle savedInstanceState) {
Button your_button = (Button) getActivity.findViewById(R.id.your_id_button)
your_button.setOnClickListener(new OnClickListener() {
public void onClick(View v)
{
button_parking();
}
});
return inflater.inflate(R.layout.fragment_select, null);
}
private void button_parking(){
Intent myIntent = new Intent(getActivity(), parking.class);
startActivity(myIntent);
}
}

您尚未將視圖綁定到片段，因此單擊按鈕無法正常工作。您需要使用 綁定視圖。通常，您需要通過重寫如下內容來執(zhí)行綁定：findViewById()onViewCreated()
public class select_fragment extends Fragment {
@Nullable
@Override
public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
return inflater.inflate(R.layout.fragment_select, null);
}
@Override
public void onViewCreated(View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
// bind the view here.
Button button = findViewById(R.id.your_button);
button.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
//call button method here
button_parking();
}
});
}
private void button_parking() {
Intent myIntent = new Intent(f, parking.class);
startActivity(myIntent);
}
}
