向Fragment传递参数

在执行一些动作时需要传递变量到 MyFragment，
解决方案：使用newInstance

public class MyFragment extends Fragment {public static MyFragment newInstance(int num) {MyFragment f = new MyFragment(); // Supply num input as an argument.Bundle args = new Bundle();args.putInt("num", num);f.setArguments(args); return f;}@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);mNum = getArguments().getInt("num");...}...}

Fragment myFragment = MyFragment.newInstance(1);
