輕松實現Android,iOS的一個手勢動畫效果

先來看效果

這是iOS下的效果，android下完全一致。通過do_GestureView組件和do_Animation組件，deviceone能很容易實現復雜的跨平台純原生動畫效果,這個示例就是通過手勢控制圖片上下動畫滑動實現開合效果，還支持聲音效果。

下面是主要的代碼

//index.ui.js

var do_Animator1 = mm("do_Animator");
do_Animator1.append(500, {
    y: -1334,
    curve:"Linear"
});
var do_Animator2 = mm("do_Animator");
do_Animator2.append(500, {
    y: 0,
    curve:"Linear"
});

do_Page.on("NextPagemoveing", function(){
    currentView=json_define[currentIndex].view;
    currentIndex++;
    if (currentIndex>=json_define.length) currentIndex=0;
    nextView=json_define[currentIndex].view;
    
    for(var i=0;i<json_define.length;++i){
        if (json_define[i].view != currentView && json_define[i].view != nextView){
            json_define[i].view.visible=false;
        }
        else{
            json_define[i].view.visible=true;
        }
    }
    
    currentView.fire("closingBottom", "NextPagemove");
});
do_Page.on("NextPagemove", function(){
    nextView.fire("initMoving", "NextPagemoved");
    
});
do_Page.on("NextPagemoved", function(){
    currentView.y= 0;
    nextView.y= 1332;
    do_ALayout_main.y=0;
    do_ALayout_main.redraw();
    do_ALayout_main.animate(do_Animator1, function(){
        nextView.fire("opening");
    });
});



do_Page.on("PrePagemoveing", function(){
    currentView=json_define[currentIndex].view;
    currentIndex--;
    if (currentIndex<0) currentIndex=json_define.length -1;
    nextView=json_define[currentIndex].view;
        
    currentView.fire("closingHead", "PrePagemove");
});
do_Page.on("PrePagemove", function(){
    nextView.fire("initMoving", "PrePagemoved");    
});
do_Page.on("PrePagemoved", function(){
    for(var i=0;i<json_define.length;++i){
        if (json_define[i].view != currentView && json_define[i].view != nextView){
            json_define[i].view.visible=false;
        }
        else{
            json_define[i].view.visible=true;
        }
    }
    currentView.y= 1332;
    nextView.y= 0;
    do_ALayout_main.y=-1334;
    do_ALayout_main.redraw();
    do_ALayout_main.animate(do_Animator2, function(){
        nextView.fire("opening");
    });
});
