自定义命名空间

//  xmlns:rcplatform="http://rcplatform.com/apk/res/android"
//   


    private void parseParams(AttributeSet attrs) {
        String namespace = "http://rcplatform.com/apk/res/android";
        // String sdkKey = attrs.getAttributeValue(namespace, "sdk_key");

解析xml文件的自定义属性

//  xmlId ==> R.xml.scene_filter_list

//  private List parseList(Context context, int xmlId) {

//      // 开始解析
//      XmlResourceParser parser = null;
//      try {
//          // 从XML中获取到相应的属性列表
//          parser = context.getResources().getXml(xmlId);
//          AttributeSet attrs = Xml.asAttributeSet(parser);
//
//          // 检查根元素
//          beginDocument(parser, ROOT_ELEMENT);
//
//          final int depth = parser.getDepth();
//          // 遍历XML
//          int type;
//          while (((type = parser.next()) != XmlPullParser.END_TAG || parser
//                  .getDepth() > depth) && type != XmlPullParser.END_DOCUMENT) {
//              if (type != XmlPullParser.START_TAG) {
//                  continue;
//              }
//              // 按照thumb item类型解析出相应的数据
//              // ThumbItem包含了自定义属性
//              TypedArray a = context.obtainStyledAttributes(attrs,
//                      R.styleable.ThumbItem);
//
//              // parser.getAttributeValue(null, name);
//              int id = a.getInt(R.styleable.ThumbItem_id, 0);
//              String desc = a.getString(R.styleable.ThumbItem_desc);
//              int iconRes = a.getResourceId(R.styleable.ThumbItem_icon, 0);
//              //Drawable icon = a.getDrawable(R.styleable.ThumbItem_icon);
//              
//              // 生成Item并且加入列表
//              EffectItem item = new EffectItem(id, desc, iconRes);
//              list.add(item);
//
//              // 回收属性列表
//              a.recycle();
//          }
//      } catch (XmlPullParserException e) {
//      } catch (IOException e) {
//      } finally {
//          try {
//              parser.close();
//          } catch (Exception e) {
//              e.printStackTrace();
//          }
