Android编程之代码创建布局实例分析

本文实例讲述了android编程之代码创建布局使用方法。分享给大家供大家参考，具体如下：

大概描述一下效果：最外层是一个 relativelayout 里面有自定义个linearlayout，每个linearlayout有两个textview。that's it !!!

private void initview() {
  // 获取xml的relativelayout
  layout = (relativelayout) findviewbyid(r.id.liner);
  for (int i = 0; i < 5; i++) {
   relativelayout.layoutparams relativeparams = new relativelayout.layoutparams(
     viewgroup.layoutparams.match_parent, viewgroup.layoutparams.wrap_content);
   // 每行都有一个linearlayout
   linearlayout llayout = new linearlayout(mcontext);
   llayout.setid(i + 10);
   llayout.setorientation(linearlayout.horizontal);
   linearlayout.layoutparams llayoutlayoutparams = new linearlayout.layoutparams(
     viewgroup.layoutparams.match_parent, viewgroup.layoutparams.wrap_content);
   llayout.setlayoutparams(llayoutlayoutparams);
   textview tv = new textview(mcontext);
   tv.setid(i);
   tv.settext("这是第" + i + "个文本框");
   tv.settextcolor(color.blue);
   textview tv_num = new textview(mcontext);
   tv_num.setid(i + 20);
   tv_num.settext(i + "台");
   tv_num.settextcolor(color.red);
   // 为textview添加长高设置
   linearlayout.layoutparams layoutparams_txt = new linearlayout.layoutparams(
     viewgroup.layoutparams.wrap_content, viewgroup.layoutparams.wrap_content);
   tv.setlayoutparams(layoutparams_txt);
   tv_num.setlayoutparams(layoutparams_txt);
   // 添加到每行的linearlayout中
   llayout.addview(tv);
   llayout.addview(tv_num);
   // 每个linearlayout都在前一个的下面，第一个在顶,不处理
   if (i > 0) {
    relativeparams.addrule(relativelayout.below, i + 10 - 1);
   }
   // 把每个linearlayout加到relativelayout中
   layout.addview(llayout, relativeparams);
  }
}

希望本文所述对大家android程序设计有所帮助。
