动态使用Fragment

布局文件就不给出了=_=

public class MyFragment extends Fragment {


    public static String s1="Yeah";//用于保存getArguments()获得的参数
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        if(getArguments()!=null)
            s1=getArguments().getString("name");
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
        View view=inflater.inflate(R.layout.fragment_my, container, false);
        Button button= (Button)view.findViewById(R.id.fragment_button);

        button.setText(s1);
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

            }
        });
        return view;
    }
}

public class FragmentTestActivity extends Activity {

    int nowButton=0;int MAXBUTTON=2;
    public String MY_TAG="FFF";
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_fragment_test);
        Button button=(Button)findViewById(R.id.start_fragmentButton);
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                switch (nowButton)
                {
                    case 0:
                       //设置要传递给Fragment的参数
                        Bundle bundle=new Bundle();
                        bundle.putString("name", "Zzzzz");
                        MyFragment myFragment=new MyFragment();
                        myFragment.setArguments(bundle);
                        //开启一个事务
                        FragmentManager fragmentManager=getFragmentManager();
                        FragmentTransaction transaction=fragmentManager.beginTransaction();
                        transaction.add(R.id.linear_fratment, myFragment, MY_TAG);
                        transaction.addToBackStack(null);
                        transaction.commit();
                        break;
                    case 1:
                       getFragmentManager().popBackStack();//模拟返回栈，将Fragment退栈
                        break;
                    default:break;
                }
                nowButton=(nowButton+1)%MAXBUTTON;
            }
        });

    }
}
