Android 实现ListView 3D效果 - 2 - 弹性滚动,Fling - 每天记录点滴

如果只是自动滚动和Fling效果可以使用Android 提供的辅助类Scroller。 回滚可以使用ListView 在Andorid 9版本以后支持的OverScroll达到预期效果,不过本实例的效果更酷。 首先定义一个动态效果工具类Dynamics 主要包含两个变量position位置和velocity速率。 Class SimpleDynamics extends Dynamics { private float mFrictionFactor; public SimpleDynamics(final float frictionFactor) { mFrictionFactor = frictionFactor; } @Override protected void onUpdate(final int dt) { mPosition += mVelocity * dt / 1000; mVelocity *= mFrictionFactor; } } 上面出现一个陌生的公式,这个公式涉及到“欧拉积分”: mPosition += mVelocity * dt / 1000; 通过欧拉积分由速度计算位置,其实这个公式精确度并不是很高,但是针对于手机上用为UI的移动控制精度已经足够了。 新位置 = 旧位置 + 速度 * 间隔时间 其中除以1000是为了同比缩放。 针对“欧拉积分”在计算机领域的使用细节可以查看: 《Flash ActionScript 3.0 动画高级教程》 第六章 数值积分 如果不想查看此书,网上也有把这一章的内容贴出来的: 高级物理:数值积分(欧拉积分) Kinetic List View.

Sql. 最近執行一個需要比較多查詢功能的案子,看看SQL資料夾裡面也有好多txt檔,也來整理一下這些內容好了。 這是一個常常都會運用到的查詢方式,比如說想要最新的巡察資料、最新的價格、最大的座標範圍、最老的歷史紀錄、最小的道路寬度等等;總之,各個不同的領域會有不同的需求,但通常我們不會只需要那個最大或最小的值,而是需要利用這個值去做為篩選的條件,例如:與目前時間最接近某個商品的報價。 要找出"最新"、"最大"、最舊"或"最小",不外乎就是使用Min與Max函式,比如說要由Data資料表取得最大年份:select max(DateYear) as MaxYear from Data要取得號碼是25的最小報價是哪天:select min(price) as MinMoney from Data where NO=25諸如此類的方式就可以取得我們想找到的數值。 但是我們不會只要這個值,我們會希望利用最大年份去查詢某一個資料表,所以必須使用子查詢的概念,將所獲得的"最大值"或"最小值"再去進行一次查詢:Select A欄,B欄,C欄from Data,(select max(DateYear) as MaxYear from Data) as MaxYearTablewhere Data.DateYear = MaxYearTable.MaxYear and 其他篩選條件 由上面可以看的出來,我們所做的是對我們原始的資料表與取得最大值的資料表進行查詢,然後在where條件設定原始資料表的年份要等於子查詢所得的年份;如此就可以很輕鬆的篩選出某一個資料表某欄最大(最小)時的全部資料。 舉個簡單的例子:1.資料庫原始資料:是一個有五個設施的資料,1、2、3設施巡查了一次,第4個巡查三次,第5個則看了四次,如果我們希望列出最新的巡察結果該怎麼做勒? 2. 3. Ola的家: Android學習_對SQLite查詢(query方法)取得Cursor. 對SQLite查詢只有兩行語法:第一行是取得資料庫(寫在該篇的Ola_SQLiteOpenHelper內,所以可以用this直接取得)。 第二行就是類似於SQL語法的查詢方式,分別是哪張表、哪幾欄、條件式、條件式的篩選值、groupBy、having與 orderBySQLiteDatabase db = this.getReadableDatabase();Cursor cursor = db.query(table, columns, selection, selectionArgs, groupBy, having, orderBy); 從上圖可以看出columns與selectionArgs是傳入陣列型態,所以我們可以以陣列的方式放入需要查的各個欄位名稱或是我們所下的條件式的篩選內容。

就像上圖"f_name=? And f_address=? "為篩選條件,query方法就會依照陣列順序填入問號(?) 美化ListView(SimpleAdapter) - 开发园地.
