從sqlite更改爲解析

Question

我想改變我的所有功能訪問sqlite解析。 我是新來解析並找不到任何解決方案。

我已經成功地改變了功能

public void register(String email,String password) { 
    ParseObject o = new ParseObject("register"); 
    o.put("email", email); 
    o.put("password", password); 
    o.saveInBackground(); 
    //SQLiteDatabase db = getWritableDatabase(); 
    //db.execSQL("insert into t_userInfo(email,password) values('" 
      //+ email + "','" + password + "')"); 
} 

目前正在對下一功能，將需要一些幫助

public Cursor login(String email,String password){ 
    SQLiteDatabase db = getReadableDatabase(); 
    Cursor cursor = db.rawQuery("select * from t_userInfo where email='"+email+"' and password='"+password+"'", null); 
    return cursor; 
} 

public Cursor findInfoByEmail(String email){ 
    SQLiteDatabase db = getReadableDatabase(); 
    Cursor cursor = db.rawQuery("select * from t_userInfo where email='"+email+"'", null); 
    return cursor; 
} 

感謝

首先，你可能想看看「解析」方式來處理用戶註冊和登錄，而不是編寫自己的邏輯。

但是，要回答你的問題。爲了從Parse獲取數據，你可以這樣做。

ParseQuery query = new ParseQuery("register"); 
query.whereEqualTo("email", "<insertemailhere>"); 
query.getFirstInBackground(new GetCallback() { 
    public void done(ParseObject* object, ParseException e) { 
    if (object == null) { 
     Log.d("user", "The getFirst request failed."); 
    } else { 
     Log.d("user", "We got a object!"); 
    } 
    } 
});
