为什么我的应用程序在使用SimpleAdapter显示Listview时崩溃？

我想用SimpleAdapter生成一个ListView。我收到以下错误。请帮我解决错误。我的代码如下以及错误日志。为什么我的应用程序在使用SimpleAdapter显示Listview时崩溃？

代码SimpleAdapter

SimpleAdapter k=new SimpleAdapter(getActivity(),val,R.layout.contact,new String[]{"name,path"},new int[]{R.id.example_itemname,R.id.path}) 
    { 
     @Override 
     public View getView (int position, View convertView, ViewGroup parent) 
      { 

final View v = super.getView(position, convertView, parent); 
//some codes more here 

       return v; 
      } 
    }; 
swipy.setAdapter(k);

其中val获取其值

public ArrayList<HashMap<String, String>> swipelistdata() { 
ArrayList<HashMap<String, String>> wordList; 
wordList = new ArrayList<HashMap<String, String>>(); 

String selectQuery = "SELECT * FROM contacts"; 

SQLiteDatabase database = this.getWritableDatabase(); 
Cursor cursor = database.rawQuery(selectQuery, null); 
if (cursor.moveToFirst()) { 
    do { 
     HashMap<String, String> map = new HashMap<String, String>(); 

     map.put("name", cursor.getString(1)); 
     map.put("path", cursor.getString(3)); 

     wordList.add(map); 
    } while (cursor.moveToNext()); 
}cursor.close(); 
database.close(); 

return wordList; 
}

ArrayIndexOutOfBoundsException异常发生在哪里？ – shkschneider

Dude您试图获取索引1值，其索引0处只有一个数据。 – user1728071

val使用以下代码val = db.swipelistdata（）;从数据库中检索数据。我想它在那里发生 – user3256145

数据库的代码，我认为你的错误是在这里

new String[]{"name,path"},new int[]{R.id.example_itemname,R.id.path}

数组必须具有相同的长度。试试这个：

new String[]{"name","path"},new int[]{R.id.example_itemname,R.id.path})

这样改变你的代码。

boolean isPresent = true; 
Cursor cursor = database.rawQuery(selectQuery, null); 
if (cursor.moveToFirst()) { 
    do { 
     HashMap<String, String> map = new HashMap<String, String>(); 

     map.put("name", cursor.getString(1)); 
     map.put("path", cursor.getString(3)); 

     wordList.add(map); 
     isPresent = cursor.moveToNext() 
    } while (isPresent);

希望这会起作用。让我知道它是否有效。
