這幾個月都是在做招財進寶項目，一個高收益低風險的理財APP，有興趣的可以下載玩玩，收益不錯哦！！！

招財進寶下載地址：http://8.shengpay.com/

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）：

一、大致界面介紹：

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：

	}
	
	private void addChild(){

			ImageView image = new ImageView(context);
			image.setBackgroundResource(R.drawable.gesture_node_normal);
			this.addView(image);
			invalidate();

	}

		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);
        }
	}

	 */
	public void clearDrawlineState(long delayTime) {
		gestureDrawline.clearDrawlineState(delayTime);
	}

}

5. GestureVerifyActivity.java 手勢密碼校驗界面

代碼如下：

			return "";

		StringBuilder builder = new StringBuilder();
		builder.append(phoneNumber.subSequence(0,3));
		builder.append("****");

		return builder.toString();
	}
	
	

	@Override

}

以上是手勢密碼實現的關鍵代碼，我把項目中的模塊代碼整理出來，新建了一個project，供大家分享和交流
