Button和AlertDialog没有响应

Question

我正在尝试通过cPanel Hosting将我的项目应用程序与在线数据库连接。我在Android Studio中使用了AlertDialog.Builder，setOnClickListener，Try和Catch，但它不起作用。我正在使用这个登录页面。登录按钮不会将我重定向到Home活动。警报对话框也不会出现。

这是我的登录页面的Java文件，

package daffaalmer.bloom2nd;

import android.app.AlertDialog;
import android.content.Intent;
import android.support.v7.app.AppCompatActivity; 

import android.os.Bundle;

import android.widget.TextView;

import com.android.volley.toolbox.Volley;

import org.json.JSONException; 
import org.json.JSONObject;

public class Login extends AppCompatActivity {

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

    final EditText EditTextEmail = (EditText) 
findViewById(R.id.EditTextEmail);
    final EditText EditTextPassword = (EditText) 
findViewById(R.id.EditTextPassword);
    final Button ButtonLogin = (Button) findViewById(R.id.ButtonLogin);
    final TextView TextViewRegister = (TextView) 
findViewById(R.id.TextViewRegister);

    TextViewRegister.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent registerIntent = new Intent(Login.this, Register.class);
            Login.this.startActivity(registerIntent);
        }
    });

    ButtonLogin.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            final String email = EditTextEmail.getText().toString();
            final String password = EditTextPassword.getText().toString();

            Response.Listener<String> responseListener = new 
Response.Listener<String>() {
                @Override
                public void onResponse(String response) {
                    try {
                        JSONObject jsonResponse = new JSONObject(response);
                        boolean success = 
jsonResponse.getBoolean("success");

                        if (success) {
                            String name = jsonResponse.getString("name");
                            String email = jsonResponse.getString("email");

                            Intent loginIntent = new Intent(Login.this, 
Home.class);
                            loginIntent.putExtra("name", name);
                            loginIntent.putExtra("email", email);
                            Login.this.startActivity(loginIntent);

                        } else {
                            AlertDialog.Builder builder = new 
AlertDialog.Builder(Login.this);
                            builder.setMessage("Login Failed")
                                    .setNegativeButton("Retry", null)
                                    .create()
                                    .show();

                        }
                    } catch (JSONException e) {
                        e.printStackTrace();
                    }

                }
            };

            LoginRequest loginRequest = new LoginRequest(email, password, 
            responseListener);
            RequestQueue queue = Volley.newRequestQueue(Login.this);
            queue.add(loginRequest);

        }
    });
}
}

这是我的登录页面的XML文件，

这是我的LoginRequest的Java文件，

package daffaalmer.bloom2nd;

import com.android.volley.Response;
import com.android.volley.toolbox.StringRequest;

import java.util.HashMap;
import java.util.Map;

public class LoginRequest extends StringRequest {

private static final String LOGIN_REQUEST_URL = 
"daffaalmerf.5gbfree.com/Login.php";
private Map<String, String> params;

public LoginRequest(String email, String password, Response.Listener<String> 
listener){
    super(Method.POST, LOGIN_REQUEST_URL, listener, null );
    params = new HashMap<>();
    params.put("email", email);
    params.put("password", password);

}

@Override
public Map<String, String> getParams() {return params;}

}

这是我在数据库中的Login.php文件

<?php
$con = mysqli_connect("daffaalmerf.5gbfree.com", "daffaalm_almer", 
"daffaalm2849", "daffaalm_pribadi_data");

$email = $_POST["email"];
$password = $_POST["password"];

$statement = mysqli_prepare($con, "SELECT * FROM pribadi_data WHERE email = 
? AND password = ?");
mysqli_stmt_bind_param($statement, "ss", $email, $password);
mysqli_stmt_execute($statement);

mysqli_stmt_store_result($statement);
mysqli_stmt_bind_result($statement, $userID, $name, $dateofbirth, $address, 
$phonenumber, $email, $password);

$response = array();
$response["success"] = false;  

while(mysqli_stmt_fetch($statement)){
    $response["success"] = true;  
    $response["name"] = $name;
    $response["dateofbirth"] = $dateofbirth;
    $response["address"] = $address;
    $response["phonenumber"] = $phonenumber;
    $response["email"] = $email;
    $response["password"] = $password;
}

echo json_encode($response);

?>
