本文介绍了Fancycoverflow布局工作不正常的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我在我的应用程序添加花哨的Cover Flow功能，它工作正常，但问题是，看中的Cover Flow的观点是古怪的显示。
我按照这个例子 https://github.com/davidschreiber/FancyCoverFlow
我想是这样的。
但输出我得到是这样的
我的意思是在同一时间只有个PIC是显示在屏幕上，在任何一方我不能够看到下一张图片

I added fancy cover flow in my app,It works fine but the issue is,the view of fancy cover flow is weirdly displaying..
I follow this example https://github.com/davidschreiber/FancyCoverFlow
I want something like this
but the output i am getting is like this
I mean at a time only single pic is displaying on screen,at any side i am not able to see next images
MyAdapter
class CoverAdapter extends FancyCoverFlowAdapter {
private LayoutInflater inflater;
public Activity a;

a = homeActivity;
inflater = (LayoutInflater) a.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}

public int getCount() {
return arr.size();
