1. 设置最基础的Layout对象实例作为根View

2. 对于组件child，先设置组件甲相对于其父view的LayoutParams属性params，然后再设置组件child本身的属性，最后父view调用addview(View child, LayoutParams params)即可将组件甲动态的加入父view中：

代码范例：

initWelPage = new RelativeLayout(_context);initWelPage.setTag(initWelPage);initWelPage.setBackgroundResource(R.drawable.desert);setContentView(initWelPage);RelativeLayout.LayoutParams layout = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.FILL_PARENT,280);layout.addRule(RelativeLayout.ALIGN_PARENT_LEFT);layout.addRule(RelativeLayout.ALIGN_PARENT_TOP);Utils.lady_gentle = new TextView(_context);Utils.lady_gentle.setId(1);Utils.lady_gentle.setBackgroundDrawable(null);Utils.lady_gentle.setTextSize(30);Utils.lady_gentle.setGravity(Gravity.LEFT);Utils.lady_gentle.setTextColor(Color.YELLOW);Utils.lady_gentle.setText(R.string.hello);Utils.lady_gentle.setTypeface(Typeface.DEFAULT,Tpyeface.BOLD);initWelPage.addView(Utils.lady_gentle,layout);

 另一段范例： 以RelativeLayout型对象language_bg作为根view，RelativeLayout型对象lang_body放置在父对象language_bg的中间位置，RelativeLayout型对象lang_part1位于父对象lang_body的顶部位置，ImageButton型对象language_cance放置于父对象lang_part1的右上方，最后把根view作为方法的返回值返回给调用方法的对象。

public View initPopWindow(Context _contex){     language_bg = new RelativeLayout(_context);     language_bg.setTag(language_bg);     language_bg.setBackgroundColor(0xb0000000);     RelativeLayout.LayoutParams layout1 = new RelativeLayout.LayoutParams(800,600);     layout1.addRule(RelativeLayout.CENTER_IN_PARENT);     lang_body = new RelativeLayout(_context);     lang_body.setTag(lang_body);     lang_body.setBackgroundColor(0xe0000000);     language_bg.addView(lang_body, layout1);     RelativeLayout.LayoutParams layout2 = new RelativeLayout.LayoutParams(ViewGroup.Layoutparams.FILL_PARENT, ViewGroup.LayoutParams.WRAP_CONENT);     layout2.addRule(RelativeLayout.ALIGN_PARENT_TOP);     lang_part1 = new RelativeLayout(_context);     lang_part1.setTag(lang_part1);     lang_part1.setId(1);     lang_part1.setBackgroundColor(0xe0000000);     lang_body.addView(lang_part1, layout2);     RelativeLayout.LayoutParams layout3 = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);     layout3.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);          language_cancel = new ImageButton(_context);     language_cancel.setTag(language_cancel);     language_cancel.setBackgroudColor(0x00000000);     language_cancel.setImageResource(R.drawable.canncel);     lang_part1.addView(language_cancel, layout3);     return language_bg;}
