当我从联系人列表地址数据中选择联系人姓名和地址未检索

Question

我需要从android联系人列表中获取联系人姓名和相关地址。我得到联系人姓名和他们的电话号码，但不幸的是无法获取地址详细信息。当我选择联系地址时，每次都会返回空值。

我搜索了谷歌以及stackoverflow。但无法找到解决方案。当我搜索时，我发现，地址细节在另一个单独的表中，但我用id搜索了该表，但没有从地址表中返回数据。所以请帮我解决这个问题。在此先感谢，

请找到的代码片段，我用来获取联系方式，

Answer 2

public ArrayList<String> getName(){ 

     ArrayList<String> mdetail=new ArrayList<String>(); 

     SQLiteDatabase db = this.getWritableDatabase(); 
     String selectQuery = "SELECT "+COLUMN_PERSON_NAME+" from "+TABLE_DETAIL; 

     Cursor mCursor = db.rawQuery(selectQuery, null); 

     if(mCursor.moveToFirst()){   
      do { 
       mdetail.add(mCursor.getString(mCursor.getColumnIndex(COLUMN_PERSON_NAME))); 

      } while (mCursor.moveToNext()); 
     } 
     mCursor.close(); 
     db.close(); 
     return mdetail; 
    } 



if Your data is Sucessfully added in your database just use this code to retreive from database and show in list view like this.... 


if (!db.exists()) { 
     } else { 
      mListName=baseManager.getName(); 
      listview.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1,mListName)); 
     }
