我想從活動切換到片段。我確實認爲我的代碼是正確的。但我仍然得到了logcat中的錯誤，無法加載視圖。請告訴我我錯在哪裏。Logcat錯誤：無法在android片段中加載視圖
我的logcat：

我的活動文件：

FragmentTransaction transaction = getFragmentManager()
.beginTransaction();
transaction.replace(R.id.content_frame, newFragment);

transaction.commit();

}
我WordFragment類：
package com.example.test;
import android.app.Fragment;
import android.app.FragmentTransaction;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
import android.widget.TextView;
public class WordFragment extends Fragment {
public WordFragment() {
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.activity_word, container, false);
return view;
}
}
好的。我確實添加了content_frame，但改變了它的ID。這是我無法找出我的錯誤的原因.. – Falguni 2014-10-01 19:39:05
