Android 动态获取资源文件的id

在Fragment中获取图片的id：

            String tv = "tv_tianqi_tomorrow";
            int tvId = getResources().getIdentifier(tv + (i - 1), "id", getContext().getPackageName());
            TextView tvDay = (TextView) getBaseRootView().findViewById(tvId);

在Fragment的RecyclerViewAdapter中，因为要加载不同类型的布局，所以想到了动态加载布局的id，一番探索，得出成果，通过设置type来区别，就不用if来判断重复写LayoutInflater的代码了，并且将布局的id设置成有规律性，如下所示，动态获取布局文件的id：

        //四个布局
        R.layout.fragment_homeforcunt_tomorrow
        R.layout.fragment_homeforcunt_week
        R.layout.fragment_homeforcunt_month
        R.layout.fragment_homeforcunt_year
        type的值为 0,1,2,3
        HomeAPI.ConstellationType是字符串数组，包含tomorrow，week，month，year.
        //正常写法
        View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.fragment_homeforcunt_tomorrow, parent, false);

        //简写
        String lay = "fragment_homeforcunt_";
        int layoutId = parent.getContext().getApplicationContext().getResources().getIdentifier(lay + (HomeAPI.ConstellationType[type]), "layout", parent.getContext().getApplicationContext().getPackageName());
        View view = LayoutInflater.from(parent.getContext()).inflate(layoutId , parent, false);
