更新時(shí)間：2016年10月31日 14:51:45 作者：Saflyer

這篇文章主要介紹了Android自定義UI手勢(shì)密碼改進(jìn)版，為大家提供了手勢(shì)密碼源碼下載，,具有一定的實(shí)用性，感興趣的小伙伴們可以參考一下

在之前文章的鋪墊下，再為大家分享一篇：Android手勢(shì)密碼，附源碼下載，不要錯(cuò)過。

源碼下載：http://xiazai.jb51.net/201610/yuanma/androidLock(jb51.net).rar

先看第一張圖片的布局文件

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="手勢(shì)密碼" /> 
 
 <Button 
 android:id="@+id/btn_set_lockpattern" 
 android:layout_width="wrap_content" 
 android:layout_height="wrap_content" 
 android:layout_marginTop="50dip" 
 android:text="設(shè)置手勢(shì)密碼" /> 
 
 <Button 
 android:id="@+id/btn_verify_lockpattern" 
 android:layout_width="wrap_content" 
 android:layout_height="wrap_content" 
 android:layout_marginTop="10dip" 
 android:text="校驗(yàn)手勢(shì)密碼" /> 
 
 <TextView 
 android:layout_width="wrap_content" 
 android:layout_height="wrap_content" 
 android:layout_marginTop="10dip" 
 android:text="密碼圖案是大2"/> 
 
</LinearLayout>

再看上面布局的java代碼
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); 
 } 
}

另外看下工具類和bean類
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();// 手機(jī)屏幕的寬度 
 int height = windowManager.getDefaultDisplay().getHeight();// 手機(jī)屏幕的高度 
 int result[] = { width, height }; 
 return result; 
 } 
}

再看9宮格的單位bean類
GesturePoint

package com.wujay.fund.entity; 
 
 
import com.wujay.fund.R; 
import com.wujay.fund.common.Constants; 
 
import android.widget.ImageView; 
 
public class GesturePoint { 
 /** 
 * 狀態(tài)值 
 */ 
 private int pointState; 
 
 /** 代表這個(gè)Point對(duì)象代表的數(shù)字，從1開始(直接感覺從1開始)*/ 
 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 + "]"; 
 } 
}

再看每個(gè)點(diǎn)位的3種狀態(tài)
Constants

package com.wujay.fund.common; 

public class Constants { 
public static final int POINT_STATE_NORMAL = 0; // 正常狀態(tài) 
public static final int POINT_STATE_SELECTED = 1; // 按下狀態(tài) 
public static final int POINT_STATE_WRONG = 2; // 錯(cuò)誤狀態(tài) 

}

再看來繪制密碼的界面
