이진 XML 파일 줄 # 14 : 클래스 조각을 부 풀리는 중 오류가 발생했습니다.

Question

처음으로 appcompat_v7을 사용하여 탐색 서랍을 만들려고합니다. 일식에 의해 제안 된 사전 정의 된 활동을 사용하여 프로젝트를 만들면 모든 것이 잘 작동합니다. 하지만 fragment_navigation_drawer 파일을 변경하면 오류가 발생하고 앱을 실행할 때마다 응용 프로그램이 중단됩니다.

그들은 당신이 일식의 제안을 사용하여 새 프로젝트를 만들 때에있는 모든 다른 것들 자바 파일에서 동일합니다. 난 그냥 두 파일

fragment_navigation_drawer.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    tools:context="com.android.apps.mobileclub.ui.NavigationDrawerFragment" > 

    <ListView 
     android:id="@+id/nav_list" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:background="#cccc" 
     android:choiceMode="singleChoice" 
     android:divider="@android:color/transparent" 
     android:dividerHeight="0dp" /> 

    <ProgressBar 
     android:id="@+id/nav_progress" 
     style="?android:attr/progressBarStyleLarge" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_centerHorizontal="true" 
     android:layout_centerVertical="true" /> 

</RelativeLayout> 

및 NavigationDrawerFragment.java 의 OnCreateView에서

을 변경

View mainView = inflater.inflate(R.layout.fragment_navigation_drawer, 
       container, false); 
     mDrawerListView = (ListView) mainView.findViewById(R.id.nav_list); 
     mNavProgress = (ProgressBar) mainView.findViewById(R.id.nav_progress); 
     cHandler = new HttpClientHandler(); 

메신저 잘못가는 곳을 가르쳐주세요?

감사합니다.

Answer 1

잘못된 클래스를 가져 왔다고 생각합니다. 당신이 뒤로 Compability가에 대한 APPCOMPAT 사용하는 경우 당신이

import android.support.v4.app.Fragment; 
import android.support.v4.app.FragmentManager; 

확인을 사용해야이 코드에서 어쩌면 당신은이 곳을 missplaced. FragmentTransaction을 사용하는 경우에도 확인해야합니다.
