InflateException在＃7行的二進制XML文件：錯誤的膨脹類的片段

我一直在做這個問題的一些研究，但沒有解決方案還沒有爲我工作。我在片段類中添加了空的構造函數，並嘗試了不同的片段導入，但似乎沒有任何工作。我希望你們能幫助我！InflateException在＃7行的二進制XML文件：錯誤的膨脹類的片段

我的活動：

package com.example.com.example.android.rssfeed; 

import android.app.Activity; 
import android.os.Bundle; 

public class RssfeedActivity extends Activity implements MyListFragment.OnItemSelectedListener { 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_rssfeed); 
} 

public void onRssItemSelected(String link) { 
    DetailFragment fragment = (DetailFragment) getFragmentManager().findFragmentById(R.id.detailFragment); 

    if (fragment != null && fragment.isInLayout()) { 
     fragment.setText(link); 
    }//end if 
}//end method onRssItemSelected 

}//end class

我的片段：

package com.example.com.example.android.rssfeed; 
import android.app.Activity; 
import android.os.Bundle; 
import android.app.Fragment; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 
import android.widget.Button; 


public class MyListFragment extends Fragment { 

public MyListFragment() { 

} 

private OnItemSelectedListener listener; 


@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 
    View view = inflater.inflate(R.layout.fragment_rsslist_overview, container, false); 
    Button button = (Button) view.findViewById(R.id.btn1); 
    button.setOnClickListener(new View.OnClickListener() { 

     @Override 
     public void onClick(View v) { 
      updateDetail(); 
     }//end onClick 
    }); 
    return view; 
}//end onCreateView 

public interface OnItemSelectedListener { 
    public void onRssItemSelected(String link); 
}//end onItemSelectedListener 

@Override 
    public void onAttach(Activity activity) { 
    super.onAttach(activity); 

     if (activity instanceof OnItemSelectedListener) { 
      listener = (OnItemSelectedListener) activity; 

     } else { 
      throw new ClassCastException(activity.toString() 
        + "Must implement MyListFragment.OnItemSelectedListener"); 
     }//end else 

}//end onAttach 

//May also be triggered from the activity 
public void updateDetail() { 
    //Create fake data 
    String newTime = String.valueOf(System.currentTimeMillis()); 
    // Send data to Activity 
    listener.onRssItemSelected(newTime); 
}//end method updateDetail 
}//end class

Caused by: java.lang.ClassNotFoundException: Didn't find class "com.example.android.rssfeed.MyListFragment" on path: /data/app/com.example.com.example.android.rssfeed-1.apk

更改此

class="com.example.android.rssfeed.MyListFragment"

到

class="com.example.com.example.android.rssfeed.MyListFragment"

原因是包名package com.example.com.example.android.rssfeed。

同樣

class="com.example.com.example.android.rssfeed.DetailFragment"

如果包名是一樣的

更改此

<button 
android:id="@+id/btn1" 
android:layout_width="wrap_content" 
android:layout_height="wrap_content" 
android:text="Press to Update">

要

<Button 
android:id="@+id/btn1" 
android:layout_width="wrap_content" 
android:layout_height="wrap_content" 
android:text="Press to Update" />

啊THX指出了這一點，通過了就在我的頭笑。現在它給了我：錯誤膨脹類按鈕，而是。我是否還需要向其添加類包？ – user3572555

@ user3572555不，你沒有 – Raghunandan

啊好吧，我添加了按鈕的xml粘貼。 – user3572555

變化

"class= com.example.android.rssfeed.MyListFragment"

到

"com.example.com.example.android.rssfeed.MyListFragment" 


And your problem will be solved out
