Android之代码创建布局

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);
}

}
