如何将登录活动定向到不同的用户配置文件

Question

我正在做一个Android应用程序，登录后我有两种不同类型的用户配置文件，在我的情况下是一个简单的客户端和一个具有高级配置的药剂师，我一直在互联网上查找如何指导我的登录活动根据用户帐户在我的数据库中注册但它没有帮助，我正在使用android studio。 这是我的loginactivity.java

package com.example.yh.log;

import android.app.Activity;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.app.Dialog;
import android.app.ProgressDialog;
import android.content.Intent;
import android.os.AsyncTask;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
import android.widget.Toast;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;

import java.util.logging.Logger;

public class MainActivity extends Activity {
    private EditText TextUserName;
    private EditText TextPassword;
    public static final String USER_NAME = "USERNAME";
    String username;
    String password;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);



}
public void onLoginClick(View view){
TextUserName = (EditText) findViewById(R.id.editusername);
TextPassword = (EditText) findViewById(R.id.editpassword);

username=TextUserName.getText().toString();
password=TextPassword.getText().toString();
if(username.isEmpty())
    Toast.makeText(getBaseContext(),"Entrez votre username",Toast.LENGTH_SHORT).show();
else if(password.isEmpty())
    Toast.makeText(getBaseContext(),"Entrez votre mot de passe",Toast.LENGTH_SHORT).show();
else {
    String urlString = "http://192.168.173.1/Search/login.php";
    LoginTask loginTask = new LoginTask();
    loginTask.execute(urlString);
}
}
private class LoginTask extends AsyncTask<String,Void,String>
{
    private Dialog loadingDialog;
  @Override
  protected void onPreExecute() {
  super.onPreExecute();
 loadingDialog = ProgressDialog.show(MainActivity.this, "Please wait", "Loading...");
}
    @Override
    protected String doInBackground(String... params) {
        HttpURLConnection c=null;
        try {
            String urlString=params[0];
            URL url=new URL(urlString);
            c=(HttpURLConnection)url.openConnection();
            c.setRequestMethod("POST");
            c.setConnectTimeout(15000 /* milliseconds */);
            c.setDoInput(true);
            c.setDoOutput(true);
            c.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
            String s = "username="+username+"&password=" + password;
        c.setFixedLengthStreamingMode(s.getBytes().length);
        PrintWriter out = new PrintWriter(c.getOutputStream());
        out.print(s);
        out.close();

        c.connect();
        int mStatusCode = c.getResponseCode();
        String result="";
        switch (mStatusCode) {
            case 200:
                BufferedReader br = new BufferedReader(new InputStreamReader(c.getInputStream()));
                StringBuilder sb = new StringBuilder();
                String line;
                while ((line = br.readLine()) != null) {
                    sb.append(line).append("\n");
                }
                br.close();
                result =  sb.toString();

        }
        return result;
    } catch (Exception ex) {
        Logger.getLogger(getClass().getName()).log(Level.SEVERE, null, ex);
        return "Error connecting to server";
    } finally {
        if (c != null) {
            try {
                c.disconnect();
            } catch (Exception ex) {
               Logger.getLogger(getClass().getName()).log(Level.SEVERE, null, ex);
                }
            }
        }
    }
@Override
protected void onPostExecute(String s) {
        //super.onPostExecute(s);
        String ss = s;
        loadingDialog.dismiss();
        if(ss.equals("successclient\n")) {
            Intent intent = new Intent(MainActivity.this, UserProfile.class);
        }else {
            if (ss.equals("successpharmacien\n")) {
                Intent intent = new Intent(MainActivity.this, PharmacienProfile.class);

            intent.putExtra(USER_NAME, username);
            finish();
            startActivity(intent);
        }else{
               Toast.makeText(getApplicationContext(), ss, Toast.LENGTH_LONG).show();

    }}
}
}

这是php代码

<?php


 try
{
    // connecting to MySQL
    $bdd = new PDO('mysql:host=localhost;dbname=application;charset=utf8', 'root', '');

}
catch(Exception $e)
{

// In case of an error, we display a message and stop everything
    die('Erreur : '.$e->getMessage());

}
    //Getting values 
    $username = $_POST['username'];
    $password = $_POST['password'];



//contact surgat
// display every input one after another

$listephar = $bdd->query("SELECT * FROM phamacien  WHERE emailpharmacien='$username' AND motpasspharmacien='$password'");

$listeclient = $bdd->query("SELECT * FROM client  WHERE emailclient='$username' AND motpass='$password'");

while ($pharmacien = $listephar->fetch())
{

    //if we got some result 
    if(isset($pharmacien)){
        //displaying success 
        echo "successpharmacien";
        }else{
        //displaying failure


while ($client = $listeclient->fetch())
{
    if (isset($client)){
            echo "successclient";
        }else{
        //displaying failure
        echo "failure";


}
}}}
$listephar->closeCursor();      
$listeclient->closeCursor(); 
?>

成功登录后，从服务器返回用户类型。 现在，只要您手中有用户输入，就可以轻松完成

if(ss=="success") {


    if(usertype=="guest")
    {
    Intent intent = new Intent(MainActivity.this,UserProfile.class);         
    }else{
    Intent intent = new Intent(MainActivity.this, AdminProfile.class);
    }
    intent.putExtra(USER_NAME, username);
    startActivity(intent);
}
else{
       Toast.makeText(getApplicationContext(), "invalide username or password", Toast.LENGTH_LONG).show();

}}
