在运行时创建colorstatelist

我在下面添加了Activity,其中我尝试创建自己的自定义xml字符串,
我想解析一个ColorStateList对象

public class MainActivity extends Activity {

final String colorVals = "<?xml version=\"1.0\" encoding=\"utf-8\"?>" + 
        "<selector xmlns:android=\"http://schemas.android.com/apk/res/android\">" +
   "<item android:color=\"#333\" android:state_focused=\"true\" />" +
   "<item android:color=\"#fff\" android:state_pressed=\"true\" />" +
   "<item android:color=\"#666\" android:state_enabled=\"false\" />" +
   "<item android:color=\"#222\"/>" +
 "</selector>";

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    try {

        XmlPullParserFactory factory = XmlPullParserFactory.newInstance();
        factory.setNamespaceAware(true);
        XmlPullParser parser = factory.newPullParser();
        String xml = colorVals;
        InputStream is = new ByteArrayInputStream(xml.getBytes("UTF-8"));

        parser.setInput(is, "UTF-8");
        Resources res = getResources();
        ColorStateList colors = ColorStateList.createFromXml(res, parser);
        TextView tv = new TextView(this);
        tv.setTextColor(colors);
    } catch (Exception e) {
        Log.e("test", e.getMessage());
    }
}
}


在尝试这样做时,我得到了下一个错误:

  

10-22 16:23:04.006:E / test(16127):START_TAG(空)http://schemas.android.com/apk/res/android}android:color='#333'   {http://schemas.android.com/apk/res/android}机器人:state_focused = '真' &GT; @ 1:166   在java.io.InputStreamReader@41dcc110中:tag需要一个   'android:color'属性。


调试我创建的解析器,我在属性集中看到:
attr [i] =“Android”,
ATTR第[i + 1] = “彩色”,
我想我可能会将解析器实例化错误
