动态加载布局时设置LinearLayout中的View的权重

来源：互联网发布：女生学金融知乎编辑：程序博客网时间：2024/06/04 06:41

在写程序时遇到这么一个问题.

根据数量的多少动态加载LinearLayout的个数,每个LinearLayout内部是横向排列的三个TextView,要让每个TextView中的文字居中显示,三个TextView还要平均分布占满整个屏幕的宽度,即用JAVA代码设置每个TextView的android:layout_weight属性,再网上查询了资料之后,终于解决,现在做个记录.

goodLayout.removeAllViews();        //根据商品数量,动态生成布局        for(int i=0;i<goodList.size();i++){            //生成三个TextView            TextView tv1=new TextView(this);            TextView tv2=new TextView(this);            TextView tv3=new TextView(this);            //文字居中            tv1.setGravity(Gravity.CENTER);            tv2.setGravity(Gravity.CENTER);            tv3.setGravity(Gravity.CENTER);            tv1.setTextSize(16f);            tv2.setTextSize(16f);            tv3.setTextSize(16f);            //设置权重            tv1.setLayoutParams(new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,ViewGroup.LayoutParams.WRAP_CONTENT,1.0f));            tv2.setLayoutParams(new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,ViewGroup.LayoutParams.WRAP_CONTENT,1.0f));            tv3.setLayoutParams(new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,ViewGroup.LayoutParams.WRAP_CONTENT,1.0f));            //设置内容            tv1.setText(goodList.get(i).getCat_name());//项目            tv2.setText(goodList.get(i).getTitle());            if(goodList.get(i).getMarkup().equals("1")){                //加价                tv3.setText(goodList.get(i).getMarkup_price()+"元");                tv3.setTextColor(getResources().getColor(R.color.textred));            }else{                //不加价                tv3.setText("否");            }            //每一行的属性            LinearLayout ll=new LinearLayout(this);            ll.setLayoutParams(new ViewGroup.LayoutParams(LinearLayoutCompat.LayoutParams.MATCH_PARENT,LinearLayoutCompat.LayoutParams.WRAP_CONTENT));            ll.setOrientation(LinearLayout.HORIZONTAL);            ll.addView(tv1);            ll.addView(tv2);            ll.addView(tv3);            goodLayout.addView(ll);        }
