Android fragment实现按钮点击事件的示例讲解

@Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {  View view = inflater.inflate(R.layout.fragment_first, null);  return view; }

@Override public void onActivityCreated(@Nullable Bundle savedInstanceState) {  super.onActivityCreated(savedInstanceState);  Button sweepButton = (Button) getActivity().findViewById(R.id.image1);  sweepButton.setOnClickListener(new View.OnClickListener() {   @Override   public void onClick(View v) {    Toast.makeText(getActivity(), "nihao", Toast.LENGTH_LONG).show();//从fragment跳转到activity中startActivity(new Intent(getActivity(), PayMoneyActivity.class));   }  }); }
