10.8 LayoutInflater(布局服务)

xml,通过findViewById找到最外层的根节点final LayoutInflater inflater = LayoutInflater.from(this);LinearLayout ly = (LinearLayout) inflater.inflate(R.layout.inflate, null, false) .findViewById(R.id.ly_inflate);③为这个容器设置大小与位置信息:RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams( LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT); lp.addRule(RelativeLayout.CENTER_IN_PARENT); ④添加到外层容器中:rly.addView(ly,lp);4.LayoutInflater的inflate()方法源码最后提供下LayoutInflater的inflate()方法的源码吧，有兴趣的可以看看~，其实就是Pull解析而已~public View inflate(XmlPullParser parser, ViewGroup root, boolean attachToRoot) { synchronized (mConstructorArgs) { final AttributeSet attrs = Xml.asAttributeSet(parser); mConstructorArgs[0] = mContext; View result = root; try { int type; while ((type = parser.next()) != XmlPullParser.START_TAG && type != XmlPullParser.END_DOCUMENT) { } if (type != XmlPullParser.START_TAG) { throw new InflateException(parser.getPositionDescription() + ": No start tag found!"); } final String name = parser.getName(); if (TAG_MERGE.equals(name)) { if (root == null || !attachToRoot) { throw new InflateException("merge can be used only with a valid " + "ViewGroup root and attachToRoot=true"); } rInflate(parser, root, attrs); } else { View temp = createViewFromTag(name, attrs); ViewGroup.LayoutParams params = null; if (root != null) { params = root.generateLayoutParams(attrs); if (!attachToRoot) { temp.setLayoutParams(params); } } rInflate(parser, temp, attrs); if (root != null && attachToRoot) { root.addView(temp, params); } if (root == null || !attachToRoot) { result = temp; } } } catch (XmlPullParserException e) { InflateException ex = new InflateException(e.getMessage()); ex.initCause(e); throw ex; } catch (IOException e) { InflateException ex = new InflateException( parser.getPositionDescription() + ": " + e.getMessage()); ex.initCause(e); throw ex; } return result; } } 本节小结：本节给大家讲解了一下Android中的LayoutInflater(布局服务)，以及动态加载View和控件相关的东西，相信对初学控件的朋友带来帮助~好的，就说这么多，谢谢~
