为何ListView中唯独不能设置字体颜色？5

public class TradeActivity extends Activity {

	ListView listview;
	@Override
	public void onCreate(Bundle savedInstanceState){
		super.onCreate(savedInstanceState);
        
		setContentView(R.layout.mystock);
		
		String[] models=new String[]{"aaa","bbb","abc","adc","zzz","xcd"};
		
		listview=(ListView)findViewById(R.id.listview);
		TradeAdapter adapter=new TradeAdapter(this,models);
		listview.setAdapter(adapter);
	}
	class TradeAdapter extends BaseAdapter{
		Context context;
		String[] array;
		TradeAdapter(Context context,String[] array){
			this.context=context;
			this.array=array;
		}
		@Override
		public int getCount() {
			// TODO Auto-generated method stub
			return array.length;
		}

		@Override
		public Object getItem(int position) {
			// TODO Auto-generated method stub
			return array[position];
		}

		@Override
		public long getItemId(int position) {
			// TODO Auto-generated method stub
			return position;
		}

		@Override
		public View getView(int position, View convertView, ViewGroup parent) {
			// TODO Auto-generated method stub
			if(convertView==null){
				LayoutInflater inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
				convertView=inflater.inflate(R.layout.row_simple_list_item_2, null);
			}
			TextView textView0=(TextView)convertView.findViewById(R.id.simple_item_0);
			TextView textView1=(TextView)convertView.findViewById(R.id.simple_item_1);
			
			textView0.setText(array[position]);
			textView0.setTextColor(R.color.red);//不可以设置
			textView1.setTextSize(20);
			
			textView1.setText(array[position]);
			textView1.setTextSize(20);//可以设置
			return convertView;
		}
		
	}
}

row_simple_list_item_2.xml文件

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
     <TextView android:id="@+id/simple_item_0"
        android:layout_width="100px"
        android:layout_height="fill_parent"
		android:gravity="center"
		android:layout_alignParentLeft="true"
		/>
		
    <TextView android:id="@+id/simple_item_1"
        android:layout_width="100px"
        android:layout_height="fill_parent"
		android:gravity="center"
		android:layout_toRightOf="@id/simple_item_0"
		/>
</RelativeLayout>

很简单的一个Listview，可为什么大小可以，颜色不可以？设置了颜色的那行居然不显示文字了。

问题补充：

sunleije 写道

ListView 的xml里有个cache color hint属性，你得把前景色设成透明，后面的字体颜色才能显示出来。。。

我已经设置了啊，我把ListView中可能的颜色都设置成#00000000，可还是老样子！

问题补充：我撞鬼了，这样又可以了。

public class App extends Activity {
    /** Called when the activity is first created. */

        String[] array={"aaa","bbb","ccc","ddd","abc"};
        ListView listview=(ListView)findViewById(R.id.listview);

    		this.array=array;
    		
    	}

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
    <ListView android:id="@+id/listview"
     android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    />
    <!-- 
    android:cacheColorHint="#00000000"
     -->
</LinearLayout>

我没有使用android:cacheColorHint
