我正在尝试创建一个signUp页面，其中我要求用户输入详细信息，然后我将它们存储在数据库中，然后在点击＆＃34;注册我＆＃34;通过仅通过数据库获取按钮。

我的MainActivity类是：

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);



    }


}

3 个答案:

答案 0 :(得分：0)

您正在尝试插入这些变量？ 

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

如果这些是TextView，那么您实际上想要getText().toString()而不是

然后，您需要将这些值放入查询中，而不是插入原始字符串值。

当然也要使用ContentValues而不是原始SQL来防止SQL注入。此外，我认为列名称区分大小写。 

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();

附加说明：请勿以明文形式存储密码。为什么甚至存储确认密码？

答案 1 :(得分：-1)

尝试使用此代码

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();
    }

答案 2 :(得分：-1)

查询失败，因为您没有转义任何值，因此它假定它们是数据库中的列。

INSERT查询应该是：

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

OR 

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

为了避免所有转义，您也可以使用ContentValues方法。
