易采站长站为您分析Android编程之代码创建布局的方法,结合实例形式分析了Android通过代码创建布局的相关技巧,具有一定参考借鉴价值,需要的朋友可以参考下
本文实例讲述了Android编程之代码创建布局使用方法。，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); }
