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;

MainActivity.java

[code]

package com.example.arayuz;

import java.util.ArrayList;
import java.util.List;

import android.support.v7.app.ActionBarActivity;
import android.support.v7.app.ActionBar;
import android.support.v4.app.Fragment;

import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ListView;
import android.widget.TabHost;
import android.widget.TabHost.TabSpec;
import android.os.Build;
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);

       t = new Intent(this,Secenekler.class);
       sekme = tbHost.newTabSpec("sekme1").setIndicator("",
               getResources().getDrawable(R.drawable.settings)).setContent(t);
       tbHost.addTab(sekme);
