在普通activity下布置代码逻辑

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;
}
