行排序的逻辑
1.lua脚本部分
--------------------------此部分封装了排序的方法-------------------------------------
function unlock(sender)
local senderName=sender:getPropertyByName("name");
move[senderName]=0;
end;
function lock(sender)
local senderName=sender:getPropertyByName("name");
move[senderName]=1;
end;
function initSort(rowNames)
sort,revSort,move={},{},{};
for rowNum,rowName in pairs(rowNames) do
sort[rowNum]=rowName;
revSort[rowName]=rowNum;
end;
end;
function moveRow(rowName,moveY)
local onclick=revSort[rowName];
if moveY<0 then
near=onclick-1;
elseif moveY>0 then
near=onclick+1;
end
local rowNear=sort[near];
local senderOnclick=document:getElementsByName(rowName);
local senderNear=document:getElementsByName(rowNear);
transition:setStopListener(senderOnclick,unlock);
transition:setStopListener(senderNear,unlock);
transition:setStartListener(senderOnclick,lock);
transition:setStartListener(senderNear,lock);
transition:translateY(senderOnclick,moveY,1);
transition:translateY(senderNear,-moveY,1);
sort[onclick],sort[near]=sort[near],sort[onclick];
revSort[rowName],revSort[rowNear]=revSort[rowNear],revSort[rowName];
end;
------------------------初始化排序--------------------------------------
--参数：需要排序的控件名称,在table中的位置与初始位置需相同
initSort({"div1","div2","div3","div4"});
------------------------针对该页面调用排序-----------------------------------------
local y=0;
function clickFun(argument,sender)
y=y+argument["y"];
alert(y);
local rowName=sender:getPropertyByName("name");
local position=revSort[rowName];
local moving=0;
for i,v in pairs(move) do
moving=moving+move[v]
end;
--以下是向下移动的代码
if y>=30 and position~=4 and moving==0 then
moveRow(rowName,60);
y=0;
end;
--以下是向上移动的代码
if y<=-30 and position~=1 and moving==0 then
moveRow(rowName,-60);
y=0;
end;
end;
---------------------------设置监听-------------------------------
local div2 = document:getElementsByTagName("div2");
gesture:setDragListener(div2, clickFun);
2.页面部分（样式略）
<body name="body">
<div class="div_test1" name ="div1" border="0">
<label>row1</label>
</div>
<div class="div_test2" name ="div2" border="0">
<label>row2</label>
</div>
<div class="div_test3" name ="div3" border="0">
<label>row3</label>
</div>
<div class="div_test4" name ="div4" border="0">
<label>row4</label>
</div>
</body>
