activity传值到fragment

public class MyFragment extends Fragment {   //FragmentActivity

    public static MyFragment staticInstance = null;

    public static MyFragment getInstance() {
        if (staticInstance == null){
            staticInstance = new MyFragment();
        }
        return staticInstance;
    }
    ImageView Touxiang,Lianxifangshi,Changyongdidian,Fuwuquyu,Yijianfankui,Changjianwenti;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    }

    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        View view=inflater.inflate(R.layout.mygelin,container,false);

Touxiang=(ImageView)view.findViewById(R.id.Touxiang);   //头像
Bitmap bm = BitmapFactory.decodeFile("/sdcard/myheader/newpic.jpg"); //从本地取图片(在cdcard中获取)  //
Touxiang .setImageBitmap(Util.toRoundBitmap(bm)); //设置Bitmap

Touxiang.setOnClickListener(new View.OnClickListener(){
 @Override
public void onClick(View v){
     Intent intent=new Intent();
    // intent.setClass(MyFragment.this, NMainActivity.class);
     intent.setClass(getActivity(),NMainActivity.class);
     startActivityForResult(intent,0);        //这里使用startActivityForResult(intent,0);  从Fragment调到activity

 }
});

public void onActivityResult(int requestCode, int resultCode, Intent data){  //这里的东西是activity结束时进行的，可以传值，可以进行初始化。
    super.onActivityResult(requestCode, resultCode, data);
    Bitmap bm = BitmapFactory.decodeFile("/sdcard/myheader/newpic.jpg"); //从本地取图片(在cdcard中获取)  //
    Touxiang .setImageBitmap(Util.toRoundBitmap(bm)); //设置Bitmap
}
