zum Einfügen von Android-Daten in mysql

Question

Ich arbeite an registrieren und Login-Aktivität. Wenn ich den Namen, den Benutzernamen und das Passwort eintippe, die Informationen zugegriffen Android-Anwendung. und der Toast zeigen die Meldung 'Registrierungserfolg' an. Aber die Daten nicht in MySQL DB eingefügt. Wie kann ich es lösen? Bitte hilf mir.

Es folgt LoginActivity.java

public class LoginActivity extends Activity { 
    EditText ET_NAME,ET_PASS; 
    String login_name,login_pass; 

    @Override 

    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.login_main); 
     ET_NAME = (EditText)findViewById(R.id.user_name); 
     ET_PASS = (EditText)findViewById(R.id.user_pass); 
    } 
    public void userReg(View view) 
    { 
     startActivity(new Intent(this,RegisterActivity.class)); 
    } 
    public void userLogin(View view) 
    { 
     login_name = ET_NAME.getText().toString(); 
     login_pass = ET_PASS.getText().toString(); 
     String method = "login"; 
     BackgroundTask backgroundTask = new BackgroundTask(this); 
     backgroundTask.execute(method,login_name,login_pass); 

     Intent intent = new Intent(this, MainActivity.class); 
     intent.putExtra("ID", login_name); 
     intent.putExtra("PW", login_pass); 
     startActivity(intent); 

     finish(); 
    } 
} 

Dies ist BackgroundTask.java

public class BackgroundTask extends AsyncTask<String,Void,String> { 
    AlertDialog alertDialog; 
    Context ctx; 

    BackgroundTask(Context ctx) { 
     this.ctx = ctx; 
    } 

    @Override 
    protected void onPreExecute() { 
     alertDialog = new AlertDialog.Builder(ctx).create(); 
    } 

    @Override 
    protected String doInBackground(String... params) { 
     String reg_url = "http://35.160.135.119/webapp/register.php"; 
     String login_url = "http://35.160.135.119/webapp/login.php"; 
     String method = params[0]; 
     if (method.equals("register")) { 
      String name = params[1]; 
      String user_name = params[2]; 
      String user_pass = params[3]; 
      try { 
       URL url = new URL(reg_url)     
       HttpURLConnection httpURLConnection = (HttpURLConnection) url.openConnection(); 

       httpURLConnection.setRequestMethod("POST"); 
       httpURLConnection.setDoOutput(true); 
       //httpURLConnection.setDoInput(true); 
       OutputStream OS = httpURLConnection.getOutputStream(); 
       BufferedWriter bufferedWriter = new BufferedWriter(new OutputStreamWriter(OS, "UTF-8")); 
       String data = URLEncoder.encode("name", "UTF-8") + "=" + URLEncoder.encode(name, "UTF-8") + "&" + 
         URLEncoder.encode("user_name", "UTF-8") + "=" + URLEncoder.encode(user_name, "UTF-8") + "&" + 
         URLEncoder.encode("user_pass", "UTF-8") + "=" + URLEncoder.encode(user_pass, "UTF-8"); 


       bufferedWriter.write(data); 
       bufferedWriter.flush(); 
       bufferedWriter.close(); 
       OS.close(); 
       InputStream IS = httpURLConnection.getInputStream(); 
       IS.close(); 
       //httpURLConnection.connect(); 
       httpURLConnection.disconnect(); 
       return "Registration Success..."; 
      } catch (MalformedURLException e) { 
       e.printStackTrace(); 
      } catch (IOException e) { 
       e.printStackTrace(); 
      } 
     } else if (method.equals("login")) { 
      String login_name = params[1]; 
      String login_pass = params[2]; 
      try { 
       URL url = new URL(login_url); 
       HttpURLConnection httpURLConnection = (HttpURLConnection) url.openConnection(); 
       httpURLConnection.setRequestMethod("POST"); 
       httpURLConnection.setDoOutput(true); 
       httpURLConnection.setDoInput(true); 
       OutputStream outputStream = httpURLConnection.getOutputStream(); 
       BufferedWriter bufferedWriter = new BufferedWriter(new OutputStreamWriter(outputStream, "UTF-8")); 
       String data = URLEncoder.encode("login_name", "UTF-8") + "=" + URLEncoder.encode(login_name, "UTF-8") + "&" + 
         URLEncoder.encode("login_pass", "UTF-8") + "=" + URLEncoder.encode(login_pass, "UTF-8"); 
       bufferedWriter.write(data); 
       bufferedWriter.flush(); 
       bufferedWriter.close(); 
       outputStream.close(); 
       InputStream inputStream = httpURLConnection.getInputStream(); 
       BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream, "iso-8859-1")); 
       String response = ""; 
       String line = ""; 
       while ((line = bufferedReader.readLine()) != null) { 
        response += line; 
       } 
       bufferedReader.close(); 
       inputStream.close(); 
       httpURLConnection.disconnect(); 
       return response; 

      } catch (MalformedURLException e) { 
       e.printStackTrace(); 
      } catch (IOException e) { 
       e.printStackTrace(); 
      } 
     } 
     return null; 
    } 

    @Override 
    protected void onProgressUpdate(Void... values) { 
     super.onProgressUpdate(values); 
    } 

    @Override 
    protected void onPostExecute(String result) { 
     if (result.equals("Registration Success...")) { 
      Toast.makeText(ctx, result, Toast.LENGTH_LONG).show(); 
     } else { 
      alertDialog.setMessage(result); 
      alertDialog.show(); 
     } 
    } 
} 

Und das ist Register.java

public class RegisterActivity extends Activity { 
    EditText ET_NAME, ET_USER_NAME, ET_USER_PASS; 
    String name, user_name, user_pass; 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.register_layout); 
     ET_NAME = (EditText)findViewById(R.id.name); 
     ET_USER_NAME = (EditText)findViewById(R.id.new_user_name); 
     ET_USER_PASS = (EditText)findViewById(R.id.new_user_pass); 
    } 
    public void userReg(View view) 
    { 
     name = ET_NAME.getText().toString(); 
     user_name = ET_USER_NAME.getText().toString(); 
     user_pass = ET_USER_PASS.getText().toString(); 
     String method = "register"; 
     BackgroundTask backgroundTask = new BackgroundTask(this); 
     backgroundTask.execute(method,name, user_name, user_pass); 
     finish(); 

    } 

} 

Dieses Protokoll wird debuggen.

Answer 1

setzen, dass Code in der Post von Asynchron-Aufgabe ausführen, die Sie nach der Asynchron Aufgabe complete.like ausführen wollen ..

finish(); 

und Ihre Web Service für Daten überprüfen, die Sie dort empfangen und versuchen, Drucken Sie das Ergebnis in logcat aus, was Sie von Ihrem Server-Skript erhalten haben, anstelle von statischer "Erfolgsmeldung".
