如何在Android應(yīng)用中實(shí)現(xiàn)一個(gè)手勢(shì)密碼功能？很多新手對(duì)此不是很清楚，為了幫助大家解決這個(gè)難題，下面小編將為大家詳細(xì)講解，有這方面需求的人可以來學(xué)習(xí)下，希望你能有所收獲。
實(shí)現(xiàn)思路：
1. 正上方的提示區(qū)域，用一個(gè)類(LockIndicator.java)來實(shí)現(xiàn)，自定義view來繪制9個(gè)提示圖標(biāo)；
2. 手勢(shì)密碼繪制區(qū)域，用一個(gè)類(GestureContentView.java)來實(shí)現(xiàn)，它繼承自ViewGroup里面, 添加9個(gè)ImageView來表示圖標(biāo), 在onLayout（）方法中設(shè)置它們的位置；
3. 手勢(shì)路徑繪制， 用一個(gè)類(GestureDrawline.java)來實(shí)現(xiàn)，復(fù)寫onTouchEvent()方法，在這個(gè)方法里面監(jiān)聽TouchEvent事件: ACTION_DOWN、ACTION_MOVE、ACTION_UP事件，來繪制手勢(shì)連接不同點(diǎn)之間的路徑；
4. 9個(gè)點(diǎn)的對(duì)象，用一個(gè)類(GesturePoint.java)來實(shí)現(xiàn)，保存它的位置、狀態(tài)、背景圖片等相關(guān)信息；
5. 手勢(shì)密碼的獲取，判斷手指當(dāng)前的位置，根據(jù)滑動(dòng)路徑經(jīng)過的點(diǎn)，按順序保存繪制的點(diǎn)的順序(這里的點(diǎn)順序從上到下分別是：1,2,3,4,5,6,7,8,9)，不能有重復(fù)的點(diǎn)。
三、代碼實(shí)現(xiàn)步驟：
1.要用一個(gè)類來表示這9個(gè)點(diǎn)中的第一個(gè)點(diǎn)。里面保留有當(dāng)前點(diǎn)的上下左右的各個(gè)位置等屬性
2.自定義GroupView，用來裝9個(gè)點(diǎn)，9個(gè)點(diǎn)的顯示是通過ImageView。復(fù)寫onLayout這個(gè)方法，讓點(diǎn)按需求排列
3.定義一個(gè)可以畫線的View，復(fù)寫onTouchEvent方法，在這個(gè)方法里面進(jìn)行畫直線的操作
4.判斷用戶手指當(dāng)前的位置，取出當(dāng)前的位置去與那9個(gè)點(diǎn)中的每個(gè)點(diǎn)的位置進(jìn)行比較，如果用戶點(diǎn)的位置在某一個(gè)點(diǎn)之內(nèi)，那么當(dāng)那個(gè)點(diǎn)置換背景圖片。
