Question

我需要从android中的联系人列表中获取联系人姓名和相关地址。我收到了联系人姓名和电话号码，但遗憾的是无法获取地址详细信息。当我选择联系地址时，它每次都会返回null。

我搜索了谷歌以及stackoverflow。但无法找到解决方案。当我搜索时发现，地址详细信息在另一个单独的表中，但是我用id搜索了该表，但是没有从地址表返回数据。所以请帮我解决这个问题。提前谢谢，

请找到我用来获取联系方式的代码段，

Answer 1

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));
         }
