ListView Görüntüleme Sorunu
Herkese merhaba;
Dropbox benzeri bir arayuz tasarlamaktayım. Uygulamada TabHost aracını kullanıyorum. 1.sekmede dosyalar yer alacak. Dosya listeisini görüntülemeye çalışıyorum, hiçbir hata almama rağmen liteyi görüntüleyemiyorum. Kodlar Aşağıda;

import com.example.arayuz.*;
public class MainActivity extends TabActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
TabHost tbHost = getTabHost();
TabHost.TabSpec sekme;
Intent t;
t = new Intent(this,Sayfa1.class);
sekme = tbHost.newTabSpec("sekme1").setIndicator("",
getResources().getDrawable(R.drawable.utilities_file_archiver)).setContent(t);
tbHost.addTab(sekme);
t = new Intent(this,Sayfa2.class);
sekme = tbHost.newTabSpec("sekme2").setIndicator("",
getResources().getDrawable(R.drawable.star)).setContent(t);
tbHost.addTab(sekme);
t = new Intent(this,Sayfa3.class);
sekme = tbHost.newTabSpec("sekme1").setIndicator("",
getResources().getDrawable(R.drawable.bell)).setContent(t);
tbHost.addTab(sekme);
