我正在尝试更改我的ListView上的字体(颜色和大小)和背景.我想用不在xml上的代码行来改变它.我的列表视图如下:xml:

 <?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="10dp"
android:textSize="18sp" android:text="@string/hello">
</TextView>

我的代码是

public class NewsActivity  extends ListActivity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);

 // ArrayAdapter listItemAdapter = new ArrayAdapter( this,android.R.layout.simple_list_item_1, v_itemList );

      setListAdapter(new ArrayAdapter<String>(this, R.layout.list_item,ynetList));

      View v=getListView() ;

      ListView lv = getListView();

    private static final int TEMPLATES=4;
    private static final int USER_GUIDE = 5;
    static final String[] LIST = 
               new String[] { "QuickStart", "Custom", "CallList", "Calendar","Templates","UserGuide"};

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setListAdapter(new MobileArrayAdapter(this, LIST));
   /*Typeface font = Typeface.createFromAsset(getAssets(), "earthkid.ttf");  */

    }

    @Override
    protected void onListItemClick(ListView l, …
