public class SoundList extends ListActivity { 

int [] soundfile; 
MediaPlayer mediaPlayer; 
final Activity act = this; 

public void onCreate(Bundle savedInstanceState) {  
    super.onCreate(savedInstanceState); 
    this.setContentView(R.layout.list_item); 
    soundfile= new int[] {R.raw.sound1,R.raw.sound2}; 

    String[] newsounds = getResources().getStringArray(R.array.newsounds);   
    this.setListAdapter(new ArrayAdapter<String>(this, R.layout.list_item, android.R.id.list, newsounds)); 
    ListView lv = getListView(); 

    lv.setOnItemClickListener(new OnItemClickListener() { 
     public void onItemClick(AdapterView<?> parent, View view, 
      int position, long id) {  

      Intent intent = new Intent(getApplicationContext(), SingleListItem.class); 
      intent.putExtra("position", position); 
      startActivity(intent);  
     } 
    }); 

    LinearLayout layout = (LinearLayout)findViewById(R.id.reklam); 
    AdView adView = new AdView(this, AdSize.BANNER, "...."); 
    layout.addView(adView); 
    AdRequest request = new AdRequest();

Это должно быть так ::

list_item.xml

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" > 

    <TextView 
     android:id="@+id/label" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:text="@+id/label" 
     android:textSize="20px" > 
    </TextView> 

</LinearLayout> 

В вашей основной код: R.id.lable является идентификатор TextView вы мы должны иметь в списке list_item.

ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, 
     R.layout.list_item.xml, R.id.label, values); 
    setListAdapter(adapter); 

Ваш чудовищно делать это неправильно, я рекомендовал бы взглянуть на некоторые учебники:

сделать новый файл XML называется

list_layout.xml:

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
android:orientation="vertical" > 

<ListView 
android:id="@android:id/list" 
android:layout_width="fill_parent" 
android:layout_height="wrap_content" 
android:padding="10dip" 
android:textSize="18dip" 
android:textStyle="bold" > 
</ListView> 

<LinearLayout 
    android:id="@+id/reklam" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:orientation="vertical" > 
</LinearLayout> 
</LinearLayout> 

отпуск другой материал, каким он был, а затем он должен быть:

setContentView(R.layout.list_layout);
