Question

我正在尝试将数据插入到webhost中，在我点击之后，我的应用程序将数据插入数据库，然后返回登录页面。但是当我点击注册按钮时我的应用程序没有回到登录页面，数据没有插入，而在logcat它显示 networksecurityconfig 。我该如何解决这个问题？

RegisterRequest.java：

public class RegisterRequest extends StringRequest {
private static final String REGISTER_REQUEST_URL = " https://http://finalproject.16mb.com/public_html/android/Register.php " ;
private Map<String , String> params;

public RegisterRequest(String name , String username ,String password, Response.Listener<String>listener){
    super(Method.POST, REGISTER_REQUEST_URL, listener, null);
    params = new HashMap<>();
    params.put("name", name);
    params.put("username", username);
    params.put("password", password);
}

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

}

RegisterActivity.java：

public class RegisterActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_register);

    final EditText etName = (EditText) findViewById(R.id.etName);
    final EditText etUsername = (EditText) findViewById(R.id.etUsername);
    final EditText etPassword = (EditText) findViewById(R.id.etPassword);

    final Button bRegister = (Button) findViewById(R.id.bRegister);

    bRegister.setOnClickListener(new View.OnClickListener(){
        @Override
        public void onClick(View v) {
            final String name = etName.getText().toString();
            final String username = etUsername.getText().toString();
            final String password = etPassword.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){
                            Intent loginintent = new Intent(RegisterActivity.this, LoginActivity.class);
                            RegisterActivity.this.startActivity(loginintent);
                        }else{
                            AlertDialog.Builder builder = new AlertDialog.Builder(RegisterActivity.this);
                            builder.setMessage("Register Failed")
                                    .setNegativeButton("Retry", null)
                                    .create()
                                    .show();
                        }
                    } catch (JSONException e){
                        e.printStackTrace();
                    }
                }
            };

            RegisterRequest registerRequest = new RegisterRequest(name, username, password, responseListener );
            RequestQueue queue = Volley.newRequestQueue(RegisterActivity.this);
            queue.add(registerRequest);
        }
    });
}
}

Register.php：

<?php
$con=mysql_connect("mysql.hostinger.my","u650032727_lgr","5j5unjie0602","   u650032727_final");

$name=$_POST["name"];
$password=$_POST["password"];
$username=$_POST["username"];
$statement= mysqli_prepare($con,"INSERT INTO user(name,username,password) VALUES (?,?,?)");
mysqli_stmt_bind_param($statement,"sss",$name,$username,$password);
mysqli_stmt_execute($statement);

$response = array();
$response = ["SUCCESS"];

echo json_encode($response);
?>

要价较高：

在我的http://finalproject.16mb.com/android/Register.php),it中出现了这个错误：

＆＃39;不推荐使用：mysql_connect（）：不推荐使用mysql扩展，将来会删除它：在第2行的/home/u650032727/public_html/android/Register.php中使用mysqli或PDO

警告：mysqli_prepare（）要求参数1为mysqli，第9行/home/u650032727/public_html/android/Register.php中给出的资源

警告：mysqli_stmt_bind_param（）要求参数1为mysqli_stmt，在第10行的/home/u650032727/public_html/android/Register.php中给出为null
