Android动态添加view的方法示例

 LinearLayout typeLayout = (LinearLayout) headerView.findViewById(R.id.layout_type);
 final List<FirstTypeEntity.DataBean> firstTypeList = entity.getData();
 for (int i = 0;i<firstTypeList.size();i++){
    WindowManager wm = (WindowManager) getContext()
        .getSystemService(Context.WINDOW_SERVICE);
    int width = wm.getDefaultDisplay().getWidth();
    int height = wm.getDefaultDisplay().getHeight();
    View view = View.inflate(getActivity(),R.layout.item_first_type,null);
    LinearLayout tab = (LinearLayout) view.findViewById(R.id.tab);
    LinearLayout.LayoutParams linearParams =(LinearLayout.LayoutParams) tab.getLayoutParams(); 
    linearParams.width = width/firstTypeList.size();//根据数量来吧
    linearParams.height = width/firstTypeList.size();//根据数量来吧
    tab.setLayoutParams(linearParams); //使设置好的布局参数应用到控件
 ｝
