好像你要添加的片段多次，有没有错误，你只要有同样的观点两次，如果你改变了方向回纵向你有3 .. 。等等。

if (savedInstanceState == null) { 
    getSupportFragmentManager().beginTransaction() 
      .add(R.id.container, new SplashFragment()) 
      .commit(); 
} else { 
    getSupportFragmentManager().beginTransaction() 
      .add(R.id.container, new HomeFragment()) // <- here 
      .commit(); 
} 

使用replace或检查片段是否已添加。
