先看第一张图片的布局文件

activity_main.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:gravity="center_horizontal" >

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginTop="40dip"
        android:textSize="24sp"
        android:text="手势密码" />
    
    <Button
        android:id="@+id/btn_set_lockpattern"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginTop="50dip"
        android:text="设置手势密码" />
    
    <Button
        android:id="@+id/btn_verify_lockpattern"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginTop="10dip"
        android:text="校验手势密码" />
    
    <TextView 
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginTop="10dip"
        android:text="密码图案是大2"/>

</LinearLayout>

再看上面布局的java代码

MainActivity

package com.wujay.fund;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class MainActivity extends Activity implements OnClickListener {
	private Button mBtnSetLock;
	private Button mBtnVerifyLock;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		setUpView();
		setUpListener();
	}
	
	private void setUpView() {
		mBtnSetLock = (Button) findViewById(R.id.btn_set_lockpattern);
		mBtnVerifyLock = (Button) findViewById(R.id.btn_verify_lockpattern);
	}
	
	private void setUpListener() {
		mBtnSetLock.setOnClickListener(this);
		mBtnVerifyLock.setOnClickListener(this);
	}

	@Override
	public void onClick(View v) {
		switch (v.getId()) {
		case R.id.btn_set_lockpattern:
			startSetLockPattern();
			break;
		case R.id.btn_verify_lockpattern:
			startVerifyLockPattern();
			break;
		default:
			break;
		}
	}

	private void startSetLockPattern() {
		Intent intent = new Intent(MainActivity.this, GestureEditActivity.class);
		startActivity(intent);
	}
	
	private void startVerifyLockPattern() {
		Intent intent = new Intent(MainActivity.this, GestureVerifyActivity.class);
		startActivity(intent);
	}
}

另外看下工具类和bean类

AppUtil

package com.wujay.fund.common;

import android.content.Context;
import android.view.WindowManager;

public class AppUtil {
	public static int[] getScreenDispaly(Context context) {
		WindowManager windowManager = (WindowManager) context
				.getSystemService(Context.WINDOW_SERVICE);
		int width = windowManager.getDefaultDisplay().getWidth();// 手机屏幕的宽度
		int height = windowManager.getDefaultDisplay().getHeight();// 手机屏幕的高度
		int result[] = { width, height };
		return result;
	}
}

再看9宫格的单位bean类

GesturePoint

package com.wujay.fund.entity;


import com.wujay.fund.R;
import com.wujay.fund.common.Constants;

import android.widget.ImageView;

public class GesturePoint {
	/**
	 * 状态值
	 */
	private int pointState;

	/** 代表这个Point对象代表的数字，从1开始(直接感觉从1开始)*/
	private int num;
	private int leftX;
	private int rightX;
	private int topY;
	private int bottomY;
	private ImageView image;
	
	private int centerX;
	private int centerY;
	public GesturePoint(int leftX, int rightX, int topY, int bottomY,
			ImageView image, int num) {
		super();
		this.leftX = leftX;
		this.rightX = rightX;
		this.topY = topY;
		this.bottomY = bottomY;
		this.image = image;

		this.centerX = (leftX + rightX) / 2;
		this.centerY = (topY + bottomY) / 2;

		this.num = num;
	}

	public int getLeftX() {
		return leftX;
	}

	public void setLeftX(int leftX) {
		this.leftX = leftX;
	}

	public int getRightX() {
		return rightX;
	}

	public void setRightX(int rightX) {
		this.rightX = rightX;
	}

	public int getTopY() {
		return topY;
	}

	public void setTopY(int topY) {
		this.topY = topY;
	}

	public int getBottomY() {
		return bottomY;
	}

	public void setBottomY(int bottomY) {
		this.bottomY = bottomY;
	}

	public ImageView getImage() {
		return image;
	}

	public void setImage(ImageView image) {
		this.image = image;
	}

	public int getCenterX() {
		return centerX;
	}

	public void setCenterX(int centerX) {
		this.centerX = centerX;
	}

	public int getCenterY() {
		return centerY;
	}

	public void setCenterY(int centerY) {
		this.centerY = centerY;
	}

	public int getPointState() {
		return pointState;
	}
	
	public void setPointState(int state) {
		pointState = state;
		switch (state) {
		case Constants.POINT_STATE_NORMAL:
			this.image.setBackgroundResource(R.drawable.gesture_node_normal);
			break;
		case Constants.POINT_STATE_SELECTED:
			this.image.setBackgroundResource(R.drawable.gesture_node_pressed);
			break;
		case Constants.POINT_STATE_WRONG:
			this.image.setBackgroundResource(R.drawable.gesture_node_wrong);
			break;
		default:
			break;
		}
	}

	public int getNum() {
		return num;
	}

	public void setNum(int num) {
		this.num = num;
	}

	@Override
	public int hashCode() {
		final int prime = 31;
		int result = 1;
		result = prime * result + bottomY;
		result = prime * result + ((image == null) ? 0 : image.hashCode());
		result = prime * result + leftX;
		result = prime * result + rightX;
		result = prime * result + topY;
		return result;
	}

	@Override
	public boolean equals(Object obj) {
		if (this == obj)
			return true;
		if (obj == null)
			return false;
		if (getClass() != obj.getClass())
			return false;
		GesturePoint other = (GesturePoint) obj;
		if (bottomY != other.bottomY)
			return false;
		if (image == null) {
			if (other.image != null)
				return false;
		} else if (!image.equals(other.image))
			return false;
		if (leftX != other.leftX)
			return false;
		if (rightX != other.rightX)
			return false;
		if (topY != other.topY)
			return false;
		return true;
	}

	@Override
	public String toString() {
		return "Point [leftX=" + leftX + ", rightX=" + rightX + ", topY="
				+ topY + ", bottomY=" + bottomY + "]";
	}
}

再看每个点位的3种状态

Constants

package com.wujay.fund.common;

public class Constants {
	public static final int POINT_STATE_NORMAL = 0; // 正常状态
	public static final int POINT_STATE_SELECTED = 1; // 按下状态
	public static final int POINT_STATE_WRONG = 2; // 错误状态

}
