前段時間因產品需求，做了一個手勢密碼，跟支付寶的手勢密碼類似，這裡跟大家分享交流一下我實現的方式吧。
這篇來分享一下繪制手勢密碼的實現（主要是設置手勢密碼、校驗手勢密碼）：
圖1
圖2
圖3
圖4
圖1：手勢密碼繪制界面 【主要是繪制上方的9個提示圖標和9個宮格密碼圖標】
圖2：設置手勢密碼 【監聽手勢的輸入，TouchEvent的事件處理，獲取輸入的手勢密碼，同時顯示在上方的提示區域】
圖3：再繪制一次，兩次密碼不一致提示界面 【這裡在實現的時候，錯誤提示文字加了“左右晃動的動畫”，錯誤路徑顏色標記為紅色】
圖4：校驗手勢密碼，輸入的密碼錯誤，給予紅色路徑+錯誤文字提示
1. 正上方的提示區域，用一個類(LockIndicator.java)來實現，自定義view來繪制9個提示圖標；
2. 手勢密碼繪制區域，用一個類(GestureContentView.java)來實現，它繼承自ViewGroup裡面, 添加9個ImageView來表示圖標, 在onLayout（）方法中設置它們的位置；
3. 手勢路徑繪制， 用一個類(GestureDrawline.java)來實現，復寫onTouchEvent()方法，在這個方法裡面監聽TouchEvent事件: ACTION_DOWN、ACTION_MOVE、ACTION_UP事件，來繪制手勢連接不同點之間的路徑；
4. 9個點的對象，用一個類(GesturePoint.java)來實現，保存它的位置、狀態、背景圖片等相關信息；
5. 手勢密碼的獲取，判斷手指當前的位置，根據滑動路徑經過的點，按順序保存繪制的點的順序(這裡的點順序從上到下分別是：1,2,3,4,5,6,7,8,9)，不能有重復的點。
1.要用一個類來表示這9個點中的第一個點。裡面保留有當前點的上下左右的各個位置等屬性
2.自定義GroupView，用來裝9個點，9個點的顯示是通過ImageView。復寫onLayout這個方法，讓點按需求排列
3.定義一個可以畫線的View，復寫onTouchEvent方法，在這個方法裡面進行畫直線的操作
4.判斷用戶手指當前的位置，取出當前的位置去與那9個點中的每個點的位置進行比較，如果用戶點的位置在某一個點之內，那麼當那個點置換背景圖片。
具體實現代碼如下：
1. LockIndicator.java 圖案提示類
