@Override
public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
view = inflater.inflate(R.layout.home, container, false);
return view;
}
@Override
public void onActivityCreated(@Nullable Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
button = (Button) view.findViewById(R.id.zy);
textView = (TextView) view.findViewById(R.id.test);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
textView.setText("回應點擊事件成功");
