在这篇文章中有这样的代码

public class MainActivity extends Activity {      private FragmentManager fragmentManager;      private RadioGroup radioGroup;      @TargetApi(Build.VERSION_CODES.HONEYCOMB)      @Override      protected void onCreate(Bundle savedInstanceState) {          super.onCreate(savedInstanceState);          requestWindowFeature(Window.FEATURE_NO_TITLE);          setContentView(R.layout.weibo_tab);          fragmentManager = getFragmentManager();          radioGroup = (RadioGroup) findViewById(R.id.rg_tab);          radioGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {              @Override              public void onCheckedChanged(RadioGroup group, int checkedId) {                  FragmentTransaction transaction = fragmentManager.beginTransaction();                  Fragment fragment = FragmentFactory.getInstanceByIndex(checkedId);                  transaction.replace(R.id.content, fragment);                  transaction.commit();              }          });      }  }  ```其中有这么一行

           transaction.replace(R.id.content,fragment);

R.id.content是该activity布局文件weibo_tab.xml中的framelayout的Id
