先看第一张图片的布局文件

activity_main.xml

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 }

再看来绘制密码的界面
activity_gesture_edit.xml

再看来绘制密码的类

接下来看验证密码锁的布局

验证密码的代码实现类
