当我们片段添加到特定的布局，

我们可以使用folloing码

Fragment fragment = new SampleFragment();

FragmentManager fragmentManager = getSupportFragmentManager();

FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();

fragmentTransaction.replace(R.id.content_layout, fragment);

fragmentTransaction.commit();

或

Fragment fragment = SampleFragment.getInstance();

FragmentManager fragmentManager = getSupportFragmentManager();

FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();

fragmentTransaction.replace(R.id.content_layout, fragment);

fragmentTransaction.commit();

我不明白是什么区别片段对象定义句子。 从某些来源，当使用'Fragment.getInstance()'类似单例模​​式时，使用'getInstance(Bundle data)'方法参数将包数据传递给片段。

你能告诉我有什么区别吗？
