怎麼用？
@override
public void onclick(view v) else if (r.id.iv == v.getid())
}
原理很簡單，
package org.alex.bosszoomanim;
import org.alex.util.logutil;
public bosszoomhelper(final activity activity, final view originalview)public bosszoomhelper(final activity activity, final view originalview, final long duration)
final contentframelayout container = (contentframelayout) activity.findviewbyid(android.r.id.content);
copyimageview = new imageview(activity);
int matchparent = framelayout.layoutparams.match_parent;
framelayout.layoutparams params = new framelayout.layoutparams(matchparent, matchparent);
copyimageview.setlayoutparams(params);
if (originalview instanceof imageview) else
}copyimageview.setvisibility(view.gone);
container.addview(copyimageview);
final rect startrect = new rect();
final rect endrect = new rect();
point offsetpoint = new point();
originalview.getglobalvisiblerect(startrect);
/\*\*
\* r 是 絕對（global）座標引數，包含狀態列、actionbar、底部虛擬鍵
\* globaloffset 用於將global座標轉換成local座標，這裡的local座標，是相對於內容區的座標，也就是除了狀態列和action bar和虛擬按鍵的區域。
\* \*/
container.getglobalvisiblerect(endrect, offsetpoint);
startrect.offset(-offsetpoint.x, -offsetpoint.y);
endrect.offset(-offsetpoint.x, -offsetpoint.y);

if ((float) endrect.width() / (float) endrect.height() > (float) startrect.width() / (float) startrect.height()) else

仿Boss直聘我的介面滑動效果
好久沒有寫部落格了，最近在找工作，我在使用boss投簡歷的時候，看到boss的我的介面蠻有意思的，就想如何去實現它，可能是職業病吧，所以就打算仿一下。先看下仿的效果。其實我們拿到這個效果的時候，看到滑動，摺疊等效果就應該想到了material design，那麼我們現在就可以基本的布局下。activ...
