我想做一个简单的登录和注册应用程序,这样用户就可以创建一个帐户.(名称,用户名,密码)我使用WAMP和存储帐户的MYSQL数据库.

当我在注册表单上填写用户信息并单击注册时,我收到以下错误:

09-14 09:30:39.864    2624-2638/com.example.appname.appname E/Surface? getSlotFromBufferLocked: unknown buffer: 0xab7115e0
09-14 09:30:48.632    2624-2638/com.example.appname.appname E/Surface? getSlotFromBufferLocked: unknown buffer: 0xab7125a0
09-14 09:30:51.940    2624-2638/com.example.appname.appname E/Surface? getSlotFromBufferLocked: unknown buffer: 0xab7125a0

当我去检查数据库时,它没有存储帐户.

MainActivity.java

import android.app.Activity;
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }
    public void userReg(View v)
    {
        startActivity(new Intent(this, Register.class));
    }
    public void userLogin(View view)
    {


    }


}

Register.java

import android.app.Activity;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle; …

我在我的android模拟器E/Surface上面对这个问题:getSlotFromBufferLocked:未知缓冲区:0xab7519c0

但我找不到任何选项如何在Android Studio 1.5.1中将Android版本更新为6.0.1的模拟器

我该怎么做？

这是代码的一部分:

 EditText user,password;
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
             user = (EditText) findViewById(R.id.user);
             password = (EditText) findViewById(R.id.pass);
            Button btn = (Button) findViewById(R.id.btnLogin);


        }

            public void login(View v){
                if(JavaLike.getString(user).equals("admin")&&JavaLike.getString(password).equals("admin")){
                    Toast.makeText(MainActivity.this,"OK"+JavaLike.getString(user),Toast.LENGTH_LONG);
                }
                else{
                    Toast.makeText(MainActivity.this,"not OK"+JavaLike.getString(user),Toast.LENGTH_LONG);
                }
            }

        }
