Question

I have really no idea why it doesn’t show text.

If you look at the class 2, then then I save nimi2 as shared preference. But it doesn’t show up in class 1. I made small test. I replaces name 2 with “plaplapla” (note the “”) and it showed up as plaplapla. But I want it to show up whatever person types as his name. I am new to java. I am yet again really out of ideas :(. Can someone help?

package viimane.voimalus;

import android.app.Activity;
import android.content.Intent;
import android.content.SharedPreferences;
import android.os.Bundle;
import android.preference.PreferenceManager;
import android.widget.TextView;

public class MainStuff extends Activity {
    TextView tere;
    String nimi;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.menu);
        tere = (TextView) findViewById(R.id.tvTere);
        SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(getBaseContext());
        boolean nimiOlemas = preferences.getBoolean("nimionolemas", false);
        nimi = preferences.getString("nimi2", "");
        if (nimiOlemas == false){
             startActivityForResult(new Intent(this, nimekysija.class), 0);
             finish();
        }
        if (nimiOlemas == true){
            tere.setText("Tere " + nimi);
        }

    }
    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        // get data from shared preference here
        super.onActivityResult(requestCode, resultCode, data);
    }
}
