無法使用PHP，MySQL和Volley進行Android登錄

Question

我想在排除的幫助下爲Android應用程序設置註冊和登錄活動。我已經能夠設置註冊頁面我有登錄活動
的問題，因爲電子郵件和密碼與數據庫不匹配。我使用的是網絡服務器 有我的登錄活動

 package com.gjs.tablepay;

public class LoginActivity extends AppCompatActivity { 

EditText etxtloginemail,etxtloginpassword; 
TextView txtRegister,txtforgotpass; 
Button btnlogin; 
    PersonBean personbean; 

// Is the Request to the Server 
StringRequest stringRequest; 

// Executes the Request 
RequestQueue requestQueue; 
ArrayList<PersonBean> personList;

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_login); 

    etxtloginemail=(EditText)findViewById(R.id.editTextloginemail);

    personbean = new PersonBean(); 

    // Initialize Volley's Request Queue 
    requestQueue = Volley.newRequestQueue(this); 
    pd = new ProgressDialog(this); 

    txtRegister.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      startActivity(new Intent(LoginActivity.this,RegistrationActivity.class)); 
     } 
    }); 
    txtforgotpass.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 

       startActivity(new Intent(LoginActivity.this,ForgotpassActivity.class));

    btnlogin.setOnClickListener(new View.OnClickListener() { 
     @Override

      init(); 
     } 
    });} 

void retrievePerson(){ 

    pd.show(); 
    stringRequest = new StringRequest(Request.Method.POST, Util.RETRIEVE_URL, 

      // success 
      new Response.Listener<String>() { 
       @Override 
       public void onResponse(String s) { 
        pd.dismiss(); 
         Toast.makeText(LoginActivity.this,"yo",Toast.LENGTH_LONG).show(); 

         if(s.equalsIgnoreCase("success")){ 
          Toast.makeText(LoginActivity.this,"yo",Toast.LENGTH_LONG).show(); 
          startActivity(new Intent(LoginActivity.this,HomeActivity.class)); 

         }else{ 
          pd.dismiss(); 
          Toast.makeText(LoginActivity.this,"No Person Found",Toast.LENGTH_LONG).show(); 
         } 

        } 

      }, 

      // failure 
      new Response.ErrorListener() { 
       @Override 
       public void onErrorResponse(VolleyError volleyError) { 
        // Toast.makeText(AllPersonsActivity.this,"Some Volley Error", Toast.LENGTH_LONG).show(); 
        Log.i("AllPersonsActivity", volleyError.toString()); 
        Log.i("AllPersonsActivity",volleyError.getMessage()); 
       } 
      } 
    ); 

    // Execute the StringRequest 
    requestQueue.add(stringRequest); 

} 
    void init(){ 
      personbean.setEmail(etxtloginemail.getText().toString().trim()); 
     personbean.setPassword(etxtloginpassword.getText().toString().trim()); 
     if(personbean.validateLoginPerson()){ 

      if(Util.isNetworkConnected(this)){ 

       retrievePerson(); 

      }else{ 
       Toast.makeText(this,"Please check your connectivity",Toast.LENGTH_LONG).show(); 
      } 

     }else{ 
      Toast.makeText(this,"Please Enter Details First",Toast.LENGTH_LONG).show(); 
     } 
    } 

}

這裏是我的login.php

<?php 
$email=$_POST['email']; 
$password=$_POST['password']; 
include("dbconfig.php"); 

    $user = @mysql_query("select uid from users where email='$email' and password='$password'"); 

$row = mysql_fetch_array($user,MYSQL_ASSOC); 
     $active = $row['active']; 
$count = @mysql_num_rows($user); 

$response =array(); 

if($count==1){ 
    $response['success']=1; 
    $response['message']="Records Retrieved sucessfully"; 
}else{ 
    $response['success']=0; 
    $response['message']="Retrieval Failure"; 
} 
echo json_encode($response); 
?>

在你的代碼的代碼你缺少getParams()，你指定你的變量。 它應該是這樣的：

StringRequest request = new StringRequest(Request.Method.POST, insertURL, new Response.Listener<String>() { 
     @Override 
     public void onResponse(String response) { 
      Log.d("=======", "DEVICE ID SENT"); 
     } 
    }, new Response.ErrorListener() { 
     @Override 
     public void onErrorResponse(VolleyError error) { 
      Log.e("=======", "DEVICE ID ERROR"); 
     } 
    }) { 
     @Override 
     protected Map<String, String> getParams() throws AuthFailureError { 
      Map<String, String> parameters = new HashMap<>(); 
      parameters.put("id",userID); 
      parameters.put("deviceId", token); 
      return parameters; 
     } 
    };
