Android编程之代码创建布局实例分析

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);  }}
