隨著互聯網的不斷進步，很多支付和手機都支持手勢密碼，想知道的朋友們快隨著武林技術頻道小編進入下文來好好了解實例演示Android手勢密碼的實現吧！
一、大致界面介紹：
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 【這里在實現的時候，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
二、實現思路：
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里面, 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，在這個方法里面監聽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(這里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。
三、代碼實現步驟：
1.要用一個類來表示這9個點中的第一個點。里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，在這個方法里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，那么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
package com.snda.fund.widget; import com.snda.fund.R; import android.content.Context; import android.content.res.TypedArray; import android.graphics.Canvas; import android.graphics.Paint; import android.graphics.Paint.Style; import android.graphics.drawable.Drawable; import android.os.PowerManager; import android.text.TextUtils; import android.util.AttributeSet; import android.util.Log; import android.view.View; /** * * 手勢密碼圖案提示 * @author wulianghuan * */ public class LockIndicator extends View { private int numRow = 3; // 行 private int numColum = 3; // 列 private int patternWidth = 40; private int patternHeight = 40; private int f = 5; private int g = 5; private int strokeWidth = 3; private Paint paint = null; private Drawable patternNoraml = null; private Drawable patternPressed = null; private String lockPassStr; // 手勢密碼 public LockIndicator(Context paramContext) { super(paramContext); } public LockIndicator(Context paramContext, AttributeSet paramAttributeSet) { super(paramContext, paramAttributeSet, 0); paint = new Paint(); paint.setAntiAlias(true); paint.setStrokeWidth(strokeWidth); paint.setStyle(Paint.Style.STROKE); patternNoraml = getResources().getDrawable(R.drawable.lock_pattern_node_normal); patternPressed = getResources().getDrawable(R.drawable.lock_pattern_node_pressed); if (patternPressed != null) { patternWidth = patternPressed.getIntrinsicWidth(); patternHeight = patternPressed.getIntrinsicHeight(); this.f = (patternWidth / 4); this.g = (patternHeight / 4); patternPressed.setBounds(0, 0, patternWidth, patternHeight); patternNoraml.setBounds(0, 0, patternWidth, patternHeight); } } @Override protected void onDraw(Canvas canvas) { if ((patternPressed == null) || (patternNoraml == null)) { return; } // 繪制3*3的圖標 for (int i = 0; i < numRow; i++) { for (int j = 0; j < numColum; j++) { paint.setColor(-16777216); int i1 = j * patternHeight + j * this.g; int i2 = i * patternWidth + i * this.f; canvas.save(); canvas.translate(i1, i2); String curNum = String.valueOf(numColum * i + (j + 1)); if (!TextUtils.isEmpty(lockPassStr)) { if (lockPassStr.indexOf(curNum) == -1) { // 未選中 patternNoraml.draw(canvas); } else { // 被選中 patternPressed.draw(canvas); } } else { // 重置狀態 patternNoraml.draw(canvas); } canvas.restore(); } } } @Override protected void onMeasure(int paramInt1, int paramInt2) { if (patternPressed != null) setMeasuredDimension(numColum * patternHeight + this.g * (-1 + numColum), numRow * patternWidth + this.f * (-1 + numRow)); } /** * 請求重新繪制 * @param paramString 手勢密碼字符序列 */ public void setPath(String paramString) { lockPassStr = paramString; invalidate(); } } 2.GestureContentView.java ?手勢密碼容器類
它繼承ViewGroup，通過addView()方法添加子viewe，手勢密碼的9個輸入點(GesturePoint)、GestureDrawline手勢密碼路徑都放在這個容器當中，下面是它的具體實現方法：
package com.wujay.fund.widget; import java.util.ArrayList; import java.util.List; import android.content.Context; import android.view.View; import android.view.ViewGroup; import android.widget.ImageView; import com.wujay.fund.R; import com.wujay.fund.common.AppUtil; import com.wujay.fund.entity.GesturePoint; import com.wujay.fund.widget.GestureDrawline.GestureCallBack; /** * 手勢密碼容器類 * */ public class GestureContentView extends ViewGroup { private int baseNum = 6; private int[] screenDispaly; /** * 每個點區域的寬度 */ private int blockWidth; /** * 聲明一個集合用來封裝坐標集合 */ private List<GesturePoint> list; private Context context; private boolean isVerify; private GestureDrawline gestureDrawline; /** * 包含9個ImageView的容器，初始化 * @param context * @param isVerify 是否為校驗手勢密碼 * @param passWord 用戶傳入密碼 * @param callBack 手勢繪制完畢的回調 */ public GestureContentView(Context context, boolean isVerify, String passWord, GestureCallBack callBack) { super(context); screenDispaly = AppUtil.getScreenDispaly(context); blockWidth = screenDispaly[0]/3; this.list = new ArrayList<GesturePoint>(); this.context = context; this.isVerify = isVerify; // 添加9個圖標 addChild(); // 初始化一個可以畫線的view gestureDrawline = new GestureDrawline(context, list, isVerify, passWord, callBack); } private void addChild(){ for (int i = 0; i < 9; i++) { ImageView image = new ImageView(context); image.setBackgroundResource(R.drawable.gesture_node_normal); this.addView(image); invalidate(); // 第幾行 int row = i / 3; // 第幾列 int col = i % 3; // 定義點的每個屬性 int leftX = col*blockWidth+blockWidth/baseNum; int topY = row*blockWidth+blockWidth/baseNum; int rightX = col*blockWidth+blockWidth-blockWidth/baseNum; int bottomY = row*blockWidth+blockWidth-blockWidth/baseNum; GesturePoint p = new GesturePoint(leftX, rightX, topY, bottomY, image,i+1); this.list.add(p); } } public void setParentView(ViewGroup parent){ // 得到屏幕的寬度 int width = screenDispaly[0]; LayoutParams layoutParams = new LayoutParams(width, width); this.setLayoutParams(layoutParams); gestureDrawline.setLayoutParams(layoutParams); parent.addView(gestureDrawline); parent.addView(this); } @Override protected void onLayout(boolean changed, int l, int t, int r, int b) { for (int i = 0; i < getChildCount(); i++) { //第幾行 int row = i/3; //第幾列 int col = i%3; View v = getChildAt(i); v.layout(col*blockWidth+blockWidth/baseNum, row*blockWidth+blockWidth/baseNum, col*blockWidth+blockWidth-blockWidth/baseNum, row*blockWidth+blockWidth-blockWidth/baseNum); } } @Override protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { super.onMeasure(widthMeasureSpec, heightMeasureSpec); // 遍歷設置每個子view的大小 for (int i = 0; i < getChildCount(); i++) { View v = getChildAt(i); v.measure(widthMeasureSpec, heightMeasureSpec); } } /** * 保留路徑delayTime時間長 * @param delayTime */ public void clearDrawlineState(long delayTime) { gestureDrawline.clearDrawlineState(delayTime); } }3.GestureDrawline.java 手勢密碼路徑繪制類
根據OnTouchEvent方法的不同事件，ACTION_DOWN、ACTION_MOVE、ACTION_UP分別處理不同的邏輯。
