I'm new to android development and don't know how to go about this. Thanks public class HomeScreen extends Activity implements OnClickListener { String response = null;

public static HomeScreen object = null;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    object = this;
    // String type = getResources().getString(R.string.TYPE);
    // Logger.logger("mobile type :::::::::::: " + type);
    // if (type.equalsIgnoreCase("mobile")) {
    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
    // }
    setContentView(R.layout.home);

    findViewById(R.id.btn_call_us).setOnClickListener(this);
    findViewById(R.id.btn_email_us).setOnClickListener(this);
    findViewById(R.id.btn_panel_book).setOnClickListener(this);
    findViewById(R.id.btn_get_instant_quote).setOnClickListener(this);
    findViewById(R.id.btn_logout).setOnClickListener(this);
    ((TextView) findViewById(R.id.tv_welcome_msg_title)).setText("Welcome "
            + Comman.getPreference(HomeScreen.this, AppConstants.PRE_F_NAME, "") + "!");

    new getJustInData().execute();
}

String response;

    @Override
    protected String doInBackground(String... params) {
        try {
            response = HttpProcess.postDataOnServer(AppConstants.URL_WELCOME + "client="
                    + Comman.getPreference(HomeScreen.this, AppConstants.PRE_COMPANY_NAME, ""));
            Logger.logger("respons in welcome Message : " + response);
        } catch (Exception e) {
            response = "";
        }
        return "";
    }

    @Override
    protected void onPostExecute(String result) {
        super.onPostExecute(result);
        PDialog.dismiss();
        String msg = Comman.getPreference(HomeScreen.this, AppConstants.PRE_WELCOME, "");

        try {
            String WelComeMsgResponseList = JsonParser.readWelcomeResponse(response);
            if (WelComeMsgResponseList != null && WelComeMsgResponseList.length() > 0) {
                Comman.setPreference(HomeScreen.this, AppConstants.PRE_WELCOME, WelComeMsgResponseList);
                ((WebView) findViewById(R.id.webview)).loadData("<font style='color:#ffffff;'><MARQUEE> "
                        + WelComeMsgResponseList + "  </MARQUEE></font>", "text/html", null);
                ((WebView) findViewById(R.id.webview)).setBackgroundColor(Color.BLACK);
                return;
            }
        } catch (Exception e) {
        } catch (Error e) {
        }
        ((WebView) findViewById(R.id.webview)).loadData("<font style='color:#ffffff;'><MARQUEE> " + msg
                + " </MARQUEE></font>", "text/html", null);
        ((WebView) findViewById(R.id.webview)).setBackgroundColor(Color.BLACK);
    }

}

}

on your `TextView` use `.setText("Welcome"+username);` – Iamat8 Oct 27 '15 at 10:07 — Iamat8, Oct 27 '15 at 10:07

Save your data in ShreadPreference and handle using your logic.

you can keep revisit_Count in it as zero initially. When user come to welcome + usrname then set to 1. So when you'll come to this page again then check that count if it is 1 then show welcome back message otherwise welcome. – d.k. Oct 27 '15 at 10:14
Or maybe just a boolean, he just wants to know if it's going to be the first time, the user access the app – Simone Leoni Oct 27 '15 at 10:17
i shared my code can any1 please tell me what should i do there? – Gurleen kaur Oct 27 '15 at 10:41
check here that: String message = ""; if(Comman.getPreference(HomeScreen.this, AppConstants.IS_REVISIT, false)){ message = "Welcome back " + Comman.getPreference(HomeScreen.this, AppConstants.PRE_F_NAME, "") + "!" }else{ message = "Welcome " + Comman.getPreference(HomeScreen.this, AppConstants.PRE_F_NAME, "") + "!" Comman.setPreference(AppConstants.IS_REVISIT, true) } ((TextView) findViewById(R.id.tv_welcome_msg_title)).setText(message); – d.k. Oct 27 '15 at 10:46
You will have to take an key(IS_REVISIT) in shared preference which will be fasle initially. Is it good for you? – d.k. Oct 27 '15 at 10:51

Useshared preference for username and also store login status. e.g -> on starting application check user login status if true show user name in top of the activity else redirected to login page.

private static final String PREFER_NAME = "";

private static final String IS_USER_LOGIN = "";

public static final String KEY_NAME = "";

public static final String KEY_Password = "";
SharedPreferences pref;
SharedPreferences.Editor editor;

in create method put these lines:

    pref = context.getSharedPreferences(PREFER_NAME, PRIVATE_MODE);
    editor = pref.edit();

    editor.putBoolean(IS_USER_LOGIN, true);

    editor.putString(KEY_NAME, name);

    editor.putString(KEY_Password, password);

    editor.commit();

check if user is logged in:

public boolean isUserLoggedIn() {

    return pref.getBoolean(IS_USER_LOGIN, false);
}

private static final String PREFER_NAME = ""; what should i include in the outations? — Gurleen kaur, Oct 29 '15 at 12:29
