Javascript中基本原型的问题(Problems with basic prototyping in Javascript)

 在我看来，你可以使用自定义视图来包装项目view.And在自定义视图中，你应该overMeasure方法： 
 
@Override protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {

        // set your width and height 
        setMeasuredDimension(width, height);
}
 
 另一个想法 
 
 当你创建layoutManager ： 
 
manager.setSpanSizeLookup(new GridLayoutManager.SpanSizeLookup() {  
            @Override  
            public int getSpanSize(int position) {  
               if( position % 4 == 1 || position %4 ==2)
                   return 1;
               else
                   return 2;
            }  

  });  
 
 经理将自动设置每个项目的宽度和高度，因此您不需要设置manualy 

After almost a week of struggle, I found the fix. It's very stupid that I wasted 1 week on something like this, but here it is. Instead of calling the function setSpanSizeLookup() in the OnCreateViewHolder in CustomAdapter, it should be called when the adapter is called i.e. 
 
GridLayoutManager lm = new GridLayoutManager(context, 3, GridLayoutManager.VERTICAL, false);
lm.setSpanSizeLookup(new GridLayoutManager.SpanSizeLookup() {
    @Override
    public int getSpanSize(int position) {
        int mod = position % 4;
        if(mod == 1 || mod == 2)
            return 1;
        else
            return 2;
    }
});
mCustomView.setLayoutManager(lm);
mCustomAdapter = new CustomAdapter(imagesList);
mCustomView.setAdapter(mCustomAdapter);
 
This fixed the bug for some unknown reason.
 
NOTE: Even though, Cole suggested almost the same thing, but it was not in context with the question. He could have answered my question correctly, if he had read my current code first.
