Android手势密码实现实例代码

一、效果实现

二、实现思路：

1. 正上方的提示区域，用一个类(LockIndicator.java)来实现，自定义view来绘制9个提示图标；

2. 手势密码绘制区域，用一个类(GestureContentView.java)来实现，它继承自ViewGroup里面, 添加9个ImageView来表示图标, 在onLayout（）方法中设置它们的位置；

3. 手势路径绘制， 用一个类(GestureDrawline.java)来实现，复写onTouchEvent()方法，在这个方法里面监听TouchEvent事件: ACTION_DOWN、ACTION_MOVE、ACTION_UP事件，来绘制手势连接不同点之间的路径；

4. 9个点的对象，用一个类(GesturePoint.java)来实现，保存它的位置、状态、背景图片等相关信息；

5. 手势密码的获取，判断手指当前的位置，根据滑动路径经过的点，按顺序保存绘制的点的顺序(这里的点顺序从上到下分别是：1,2,3,4,5,6,7,8,9)，不能有重复的点。

 三、代码实现步骤：

1.要用一个类来表示这9个点中的第一个点。里面保留有当前点的上下左右的各个位置等属性

2.自定义GroupView，用来装9个点，9个点的显示是通过ImageView。复写onLayout这个方法，让点按需求排列

3.定义一个可以画线的View，复写onTouchEvent方法，在这个方法里面进行画直线的操作

4.判断用户手指当前的位置，取出当前的位置去与那9个点中的每个点的位置进行比较，如果用户点的位置在某一个点之内，那么当那个点置换背景图片。

具体实现代码如下：

1.LockIndicator.java 图案提示类

2.GestureContentView.java  手势密码容器类

它继承ViewGroup，通过addView()方法添加子view，手势密码的9个输入点(GesturePoint)、GestureDrawline手势密码路径都放在这个容器当中，下面是它的具体实现方法：

/**

*/

private List<GesturePoint> list;

private Context context;

private boolean isVerify;

private GestureDrawline gestureDrawline;

/**

* @param context

* @param isVerify 是否为校验手势密码

*/

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个图标

addChild();

// 初始化一个可以画线的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();

// 第几行

int row = i / 3;

// 第几列

int col = i ％ 3;

// 定义点的每个属性

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){

// 得到屏幕的宽度

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++) {

//第几行

int row = i/3;

//第几列

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);

// 遍历设置每个子view的大小

for (int i = 0; i < getChildCount(); i++) {

View v = getChildAt(i);

v.measure(widthMeasureSpec, heightMeasureSpec);

}

}

/**

public void clearDrawlineState(long delayTime) {

gestureDrawline.clearDrawlineState(delayTime);

}

}
