Question

세부 정보를 입력하라는 signUp 페이지를 만든 다음 저장하고 있습니다. 그 (것)들은 데이타베이스에서 그 후에 그 (것)들을 인쇄하고 "데이타베이스를 통해서만 가져 오기"버튼을 클릭하여 다른 활동에 그들을 인쇄합니다.

내 MainActivity 클래스는 다음과 같습니다

package com.example.hsports.signuppage; 

import android.content.Intent; 
import android.database.sqlite.SQLiteDatabase; 
import android.support.v7.app.AppCompatActivity; 
import android.os.Bundle; 
import android.view.View; 
import android.widget.EditText; 
import android.widget.TextView; 

public class MainActivity extends AppCompatActivity { 

    String name; 
    String emailId; 
    String password; 
    String cnfpassword; 



    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
     TextView tv=(TextView)findViewById(R.id.Title); 
     tv.setSelected(true); 

    } 

    public void storeInfo(View v) 
    { 
     name=findViewById(R.id.name).toString(); 
     emailId=findViewById(R.id.emailId).toString(); 
     password=findViewById(R.id.password).toString(); 
     cnfpassword=findViewById(R.id.cnfpassword).toString(); 


     SQLiteDatabase mydb=openOrCreateDatabase("usersInfo",MODE_PRIVATE,null); 
     mydb.execSQL("create table IF NOT EXISTS userInfo (Name varchar , EmaiId varchar , Password varchar , CnfPassword varchar);"); 
     mydb.execSQL("insert into userInfo (Name, EmaiId , Password , CnfPassword) Values(name , emailId , password , cnfpassword);"); 

     Intent i=new Intent(this,SecondActivity.class); 
     startActivity(i); 



    }

Answer 1

이러한 변수를 삽입하려고합니까?

name=findViewById(R.id.name).toString(); 
emailId=findViewById(R.id.emailId).toString(); 
password=findViewById(R.id.password).toString(); 
cnfpassword=findViewById(R.id.cnfpassword).toString(); 

사람들은 TextViews 경우

는, 당신은 실제로 대신

그런 다음 쿼리에 이 값을 넣어보다는 원시 문자열 값을 삽입해야 getText().toString()로합니다.

SQL 주입을 방지하기 위해 원시 SQL 대신 ContentValues를 사용해야합니다. 또한 컬럼 이름은 대소 문자를 구분한다고 생각합니다.

SQLiteDatabase db = this.getWritableDatabase(); 

ContentValues values = new ContentValues(); 
values.put("Name", name); // use the name variable, not the string "name" as the value 
// etc. 

db.insert("userInfo", null, values); 
db.close(); 

추가 참고 사항 : 암호를 일반 텍스트로 저장하지 마십시오. 왜 확인 암호를 저장합니까?

Answer 2

이 코드를 사용해보십시오 대신

public void insertUserInfo() { 
     SQLiteDatabase db = this.getWritableDatabase(); 

     ContentValues values = new ContentValues(); 
     values.put(Name, "name"); 
     values.put(Email, "email"); 

     db.insert(LEAD_SOURCE_TABLE, null, values); 
     db.close(); 
    } 

Answer 3

값을 이스케이프하지 않았기 때문에 쿼리가 실패 했으므로 데이터베이스의 열이라고 가정합니다.

INSERT 쿼리의 라인을 따라 뭔가해야한다 :

mydb.execSQL("INSERT INTO userInfo (Name, EmaiId , Password , CnfPassword) VALUES (\"name\" , \"emailId\" , \"password\" , \"cnfpassword\");") 

또는

mydb.execSQL("INSERT INTO userInfo (Name, EmaiId , Password , CnfPassword) VALUES ('name' , 'emailId' , 'password' , 'cnfpassword');") 

모든 탈출을 방지하기 위해, 당신은 또한 ContentValues 접근 방식을 사용할 수있다.
