Android 动态添加线性布局(.java文件内) 实现控件按比例分割空间

    {
    LinearLayout l=new LinearLayout(this);
    
    EditText  et1 = new EditText(this);
    //这里只有LinearLayout.LayoutParams 才有 .weight属性
    LinearLayout.LayoutParams  lp1=new LinearLayout.LayoutParams(0, ViewGroup.LayoutParams.WRAP_CONTENT);
      
     lp1.weight=1;//这里控制比例
    et1.setLayoutParams(lp1);
    
    l.addView(et1);
    
    EditText  et2 = new EditText(this);

    LinearLayout.LayoutParams  lp2=new LinearLayout.LayoutParams(0, ViewGroup.LayoutParams.WRAP_CONTENT);
      
     lp2.weight=2;//这里控制比例
    et2.setLayoutParams(lp2);
    
    l.addView(et2);
        
    ll.addView(l);
