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" ><TextViewandroid:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_marginTop="40dip"android:textSize="24sp"android:text="手势密码" /><Buttonandroid: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" /><Buttonandroid: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;@Overrideprotected 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);}@Overridepublic 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;}@Overridepublic 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;}@Overridepublic 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;}@Overridepublic 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}

再看来绘制密码的界面

activity_gesture_edit.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="match_parent"android:layout_height="match_parent"android:background="#48423D" ><RelativeLayoutandroid:id="@+id/top_layout"android:layout_width="match_parent"android:layout_height="46dip"android:background="#000000"android:paddingLeft="20dip"android:paddingRight="20dip"android:layout_alignParentTop="true" ><TextViewandroid:id="@+id/text_title"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_centerInParent="true"android:gravity="center"android:text="@string/setup_gesture_code"android:textSize="20sp"android:textColor="#ffffff" /></RelativeLayout><LinearLayoutandroid:id="@+id/gesture_tip_layout"android:layout_width="fill_parent"android:layout_height="wrap_content"android:layout_below="@id/top_layout"android:gravity="center"android:orientation="vertical" ><TextViewandroid:id="@+id/text_tip"android:layout_width="fill_parent"android:layout_height="wrap_content"android:gravity="center_horizontal"android:text="@string/set_gesture_pattern"android:textColor="#F98F12"android:layout_marginTop="10dip" /></LinearLayout><FrameLayoutandroid:id="@+id/gesture_container"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_below="@id/gesture_tip_layout"android:layout_gravity="center_horizontal"android:layout_marginTop="20dip" ></FrameLayout><TextViewandroid:id="@+id/text_reset"android:layout_width="fill_parent"android:layout_height="wrap_content"android:gravity="center_horizontal"android:layout_below="@id/gesture_container"android:layout_marginTop="20dip"android:text="@string/set_gesture_pattern_reason"android:textColor="#816E6A" /></RelativeLayout>

接下来看验证密码锁的布局

activity_gesture_verify.xml

<RelativeLayout 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:background="#48443c" ><LinearLayoutandroid:id="@+id/gesture_tip_layout"android:layout_width="fill_parent"android:layout_height="wrap_content"android:layout_below="@id/top_layout"android:orientation="vertical"android:paddingTop="20dip" ><TextViewandroid:id="@+id/text_tip"android:layout_width="fill_parent"android:layout_height="wrap_content"android:layout_marginTop="10dip"android:gravity="center_horizontal"android:textColor="#000000"android:visibility="invisible" /></LinearLayout><FrameLayoutandroid:id="@+id/gesture_container"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_below="@id/gesture_tip_layout" ></FrameLayout></RelativeLayout>
