错误膨胀课堂片段例外

Question

我想把一个软件包放在片段中。该捆绑必须存在于onCreate方法中。 但我得到一个空指针异常。

在活动

Bundle bundl = new Bundle(); 
String headlines[] = {"sdfsdf","sdfsd","fgfg","sdffsd"}; 
bundl.putStringArray("123", headlines); 
bundl.putStringArray("1253", headlines); 
HeadlinesFragment firstFragment = new HeadlinesFragment(); 
firstFragment.setArguments(bundl); 

的onCreate方法

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 

    // Here is the null pointer 
    headlines =getArguments().getStringArray("123"); 

    int layout = Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB ? android.R.layout.simple_list_item_activated_1 
      : android.R.layout.simple_list_item_1; 
    inserts = new ArrayAdapter<String>(getActivity(), layout, headlines); 

    setListAdapter(inserts); 
} 

布局

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:orientation="horizontal" 
android:layout_width="match_parent" 
android:layout_height="match_parent"> 

<fragment android:name="com.de.ordix.HeadlinesFragment" 
      android:id="@+id/headlines_fragment" 
      android:layout_weight="1" 
      android:layout_width="0dp" 
      android:layout_height="match_parent" /> 

<fragment android:name="com.de.ordix.ArticleFragment" 
      android:id="@+id/abwesend_fragment" 
      android:layout_weight="2" 
      android:layout_width="0dp" 
      android:layout_height="match_parent" /> 

这里错误日志

Answer 1

声明一个类和静态变量

public class global { 
    public static String headlines[] ; 
} 

现在你的代码

global.headlines = {"sdfsdf","sdfsd","fgfg","sdffsd"}; 

而且 当你想使用

inserts = new ArrayAdapter<String>(getActivity(), layout, global.headlines);
