我有一個錯誤在我rootView

Question

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

    et=(EditText)rootView.findViewById(R.id.et1); 

    String str=et.getText().toString(); 



    Fragment frag=new Fragment(); 
    Bundle bundle1=new Bundle(); 
    bundle1.putString("name", str); 
    frag.setArguments(bundle1); 
    getFragmentManager().beginTransaction().add(R.id.container_body, frag).commit(); 

    return inflater.inflate(R.layout.fragment_currentmovie, container, false); 
} 

}

它顯示rootView不能得到解決，我需要編輯文本等添加到字符串str因此使用捆綁我可以將它傳遞到下一個片段

Answer 1

嘗試此附加吹氣，然後返回。

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

View rootView = inflater.inflate(R.layout.fragment_currentmovie, container, false); 
et=(EditText)rootView.findViewById(R.id.et1); 

String str=et.getText().toString(); 



Fragment frag=new Fragment(); 
Bundle bundle1=new Bundle(); 
bundle1.putString("name", str); 
frag.setArguments(bundle1); 
getFragmentManager().beginTransaction().add(R.id.container_body, frag).commit(); 

return rootView ; 
} 
}

您需要首先它充氣：

View rootView = inflater.inflate(R.layout.fragment_currentmovie, container, false); 
... 
return rootview;
