Question

我想在android中全面了解webview，但只有设备的可见区域捕获其他区域变灰。这是代码：

$(".reset").click(function (e) {
    e.preventDefault();
    $(".product-group > .row").hide('slide',{direction:"left",distance:1900},200);//,function () {

        var product_groups = $(".product-group");
        $.ajax({
                type: 'POST',
                url: "?callback=?", 
                data: "",
                success: function(data) {
                    product_groups.html($(data).find(".product-group").html());
                    PageCenterer();
                    isOnlyTwoProductFields();
                }
            });
        //$(".product-group").html($("#product-field").html()).append($("#product-field").html());
        count=$(".product-group > .row").size();
        var index=$(".product-group > .row").index();
        console.log(index);
        $(".product-group > .row").each(function(index){
        if ($(window).width()<600) {
            $(this).find("label:first").text((index+1));
        }else{
            $(this).find("label:first").text((index+1)+"."+product);
        }
        //isOnlyTwoProductFields();
        //PageCenterer();
        });
    //});

    });

                                fos.close();
                            }
                        }
                   catch( Exception e )
                   {

                   }
          }
      });

    setContentView(w);
    w.loadUrl("http://search.yahoo.com/search?p=android");
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.activity_main, menu);
    return true;
}
}

这段代码足以解释你需要的一切
