动态使用Fragment

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;
}
});

}
}
