1：效果图

2：代码复用部分，以及用来耦合的抽象接口

抽象接口：

publicinterface IFillView //接口，暴露的抽象规则；

{

View getView();

void setBroadCast(IBroadcast iBroadcast);

}

public interface IBroadcast//回调接口，用于类之间的异步交互
{
voidsetTag(Object type);

void close();

}

复用代码

public abstractclass PoupFillViewextendsPopupWindowimplementsIBroadcast
{
    privateActivityact;
    private intwidth,height;
    privateIFillViewiFillView;

    publicPoupFillView(Activityact,IFillView iFillView)
    {
        super(act);
        this.act=act;
        this.iFillView=iFillView;
        height=act.getWindowManager().getDefaultDisplay().getHeight();
        width=act.getWindowManager().getDefaultDisplay().getWidth();
    }

    public voidinitPoupView()
    {
        setContentView(iFillView.getView());
        iFillView.setBroadCast(this);

        setFocusable(true);
        setTouchable(true);
        setHeight(height);
        setWidth(width);
        setAnimationStyle(R.style.PopumAnimation);

    }

    @Override
    public voidclose()
    {
      dismiss();
    }

}

3：扩展部分（只需实现IFillView接口即可）

public classPoupWebView implementsIFillView
{
    privateContext context;

    public PoupWebView(Context context)
    {
        this.context=context;
        initView();
        initInfo();
        initBinder();
    }

    privateView contentView;

    privateTextView tvOk;
    privateTextView tvNo;
    privateWebView webView;

    private voidinitView()
    {
        contentView= LayoutInflater.from(context).inflate(R.layout.poup_webview,null);
        tvOk= (TextView)contentView.findViewById(R.id.poup_ok);
        tvNo= (TextView)contentView.findViewById(R.id.poup_no);
        webView= (WebView)contentView.findViewById(R.id.poup_web);

    }

    privateString url;
   private voidinitInfo()
    {
        url="http://mt.sohu.com/20150923/n421957484.shtml";
    }

    private voidinitBinder()
    {
        webView.loadUrl(url);

        tvOk.setOnClickListener(newView.OnClickListener() {
            @Override
            public voidonClick(View v) {
                iBroadcast.setTag(false);
                iBroadcast.close();
            }
        });
        tvNo.setOnClickListener(newView.OnClickListener() {
            @Override
            public voidonClick(View v) {
                iBroadcast.setTag(true);
                iBroadcast.close();
            }
        });

    }

    @Override
    public View getView() {
        returncontentView;
    }

    privateIBroadcast iBroadcast;

    @Override
    public voidsetBroadCast(IBroadcast iBroadcast)
    {
       this.iBroadcast=iBroadcast;

    }
4，调用使用
final PoupFillView poupFillView=newPoupFillView(getActivity(),newPoupWebView(getActivity())) {
    @Override
    public voidsetTag(Object type) {
        Boolean logic= (Boolean) type;
        if(!logic)
        {
            getActivity().finish();
        }

    }
};
poupFillView.showAtLocation(convertView, Gravity.CENTER,0,0);

}
