之前写过3篇手势密码的demo,不过没有集成到真实的企业项目中，这几天正好领到一个手势密码项目，昨天刚好弄完，今天抽空整理下，目前还没有完善，有一些地方需要更改，不过基本的流程都可以跑通了。

Android自定义UI手势密码终结版1

先看主界面的入口把、里面有2个button(一个是设置手势密码、一个是校验手势密码)

activity_main.xml

在看主界面的代码把

MainActivity

package com.example.gesturelock; import android.app.Activity; import android.content.Intent; import android.os.Bundle; import android.view.Menu; import android.view.MenuItem; import android.view.View; import android.view.View.OnClickListener; import android.widget.Button; public class MainActivity extends Activity implements OnClickListener { private Button setting, verify; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); setting = (Button) findViewById(R.id.setting); verify = (Button) findViewById(R.id.verify); setting.setOnClickListener(this); verify.setOnClickListener(this); } @Override public void onClick(View v) { switch (v.getId()) { case R.id.setting: startActivity(new Intent(this, GestureEditActivity.class)); break; case R.id.verify: startActivity(new Intent(this, GestureVerifyActivity.class)); break; default: break; } } }

想了想还是先贴数据库把---就是存放手势密码、以及还可以输入的手势密码次数

publicSQLiteOpenHelper

package com.example.gesturelock; import android.content.ContentValues; import android.content.Context; import android.database.Cursor; import android.database.SQLException; import android.database.sqlite.SQLiteDatabase; import android.database.sqlite.SQLiteOpenHelper; public class publicSQLiteOpenHelper extends SQLiteOpenHelper{ private static String name = "publicsqlite"; private static String GESTURE_PASSWORD = "gesture_password"; private static final int version = 1; public SQLiteDatabase db; public publicSQLiteOpenHelper(Context context) { super(context, name, null, version); } @Override public void onCreate(SQLiteDatabase db) { String sqlpass = "create table " + "gesture_password"+ "(" + GesturePassword.WXID + " text not null," + GesturePassword.PASSWORD + " text not null," + GesturePassword.REMAINOPPORTUNITY + " text not null)"; db.execSQL(sqlpass); } @Override public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) { db.execSQL("DROP TABLE IF EXISTS password"); onCreate(db); } public class GesturePassword { public static final String WXID = "wxid"; public static final String PASSWORD = "password"; public static final String REMAINOPPORTUNITY = "remainopportunity"; } /** * 插入手势密码表 */ public void insertGestureInfo(SQLiteDatabase database ,String password,String times){ ContentValues values = null; try { values = new ContentValues(); values.put(GesturePassword.WXID, "001"); values.put(GesturePassword.PASSWORD, password); values.put(GesturePassword.REMAINOPPORTUNITY, ""+times); database.insert(publicSQLiteOpenHelper.GESTURE_PASSWORD, null, values); } catch (Exception e) { e.printStackTrace(); throw new SQLException(e.getMessage()); }finally{ if (values != null) { values.clear(); values = null; } } } /** * 修改手势密码表---初始化次数为8次 * * */ public void updateGestureInfo(SQLiteDatabase database,String password,String times) { ContentValues values = null; try { if (password == null) { values = new ContentValues(); values.put(GesturePassword.WXID, "001"); values.put(GesturePassword.REMAINOPPORTUNITY, ""+times); database.update(publicSQLiteOpenHelper.GESTURE_PASSWORD, values, "WXID=", new String[] { "001" }); }else { values = new ContentValues(); values.put(GesturePassword.WXID, "001"); values.put(GesturePassword.PASSWORD, password); values.put(GesturePassword.REMAINOPPORTUNITY, ""+times); database.update(publicSQLiteOpenHelper.GESTURE_PASSWORD, values, "WXID=", new String[] { "001" }); } } catch (SQLException e) { } finally { if (values != null) { values.clear(); values = null; } } } /** * 查询手势密码表有无记录 * @return */ public boolean queryGestureTableCount(SQLiteDatabase database){ Cursor cursor = null; try { cursor = database.query(publicSQLiteOpenHelper.GESTURE_PASSWORD, null, null, null, null, null, null); if (cursor != null && cursor.getCount()>0) { return true; }else { return false; } } catch (Exception e) { } finally{ if (cursor != null) { cursor.close(); cursor = null; } } return false; } /** * 查询手势密码表--查看剩余次数 * */ public String queryGestureTime(SQLiteDatabase database) { Cursor cursor = null; try { cursor = database.query(publicSQLiteOpenHelper.GESTURE_PASSWORD, null, null, null, null, null, null); if ((cursor != null) && (cursor.getCount() > 0)) { if (cursor.moveToFirst()) { int columnIndex = cursor .getColumnIndex(GesturePassword.REMAINOPPORTUNITY); return cursor.getString(columnIndex); } } } catch (Exception e) { } finally { if (cursor != null) { cursor.close(); cursor = null; } } return ""; } /** * 查询手势密码表--查看密码 * */ public String queryGesturePassword(SQLiteDatabase database) { Cursor cursor = null; try { cursor = database.query(publicSQLiteOpenHelper.GESTURE_PASSWORD, null, null, null, null, null, null); if ((cursor != null) && (cursor.getCount() > 0)) { if (cursor.moveToFirst()) { int columnIndex = cursor .getColumnIndex(GesturePassword.PASSWORD); return cursor.getString(columnIndex); } } } catch (Exception e) { } finally { if (cursor != null) { cursor.close(); cursor = null; } } return ""; } }

接下里再看工具类把--就是输入的手势密码简单MD5加密、以及屏幕尺寸工具类

/** * */ package com.example.gesturelock; import android.content.Context; import android.view.WindowManager; public class AppUtil { /** * 获取屏幕分辨�? * @param context * @return */ public static int[] getScreenDispaly(Context context) { WindowManager windowManager = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE); @SuppressWarnings("deprecation") int width = windowManager.getDefaultDisplay().getWidth(); @SuppressWarnings("deprecation") int height = windowManager.getDefaultDisplay().getHeight(); int result[] = { width, height }; return result; } }

package com.example.gesturelock; import java.security.MessageDigest; import java.security.NoSuchAlgorithmException; import android.util.Log; public class MD5EncodeUtil { public static String MD5Ecode(String gesture){ Log.i("GYL","gesture---"+gesture.toString()); byte[] toencode=gesture.toString().getBytes(); Log.i("GYL","byte[]----"+toencode.toString()); try{ MessageDigest md5=MessageDigest.getInstance("MD5"); md5.reset(); md5.update(toencode); return HexEncode(md5.digest()); }catch(NoSuchAlgorithmException e){ e.printStackTrace(); } return ""; } public static String HexEncode(byte[] toencode){ StringBuilder sb=new StringBuilder(toencode.length*2); for(byte b:toencode){ sb.append(Integer.toHexString((b&0xf0)>>>4)); sb.append(Integer.toHexString(b&0x0f)); } return sb.toString().toUpperCase(); } }

一步步来，接下来看bean类，就是每个圆点的属性

Constants

package com.example.gesturelock; 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 }

GesturePoint

package com.example.gesturelock; import android.widget.ImageView; public class GesturePoint { /** * 左边x的值 */ private int leftX; /** * 右边x的值 */ private int rightX; /** * 上边y的值 */ private int topY; /** * 下边y的值 */ private int bottomY; /** * 这个点对应的ImageView控件 */ private ImageView image; /** * 中心x值 */ private int centerX; /** * 中心y值 */ private int centerY; /** * 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; 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, int x, int y) { pointState = state; switch (state) { case Constants.POINT_STATE_NORMAL: this.image.setBackgroundResource(R.drawable.gesturewhite); break; case Constants.POINT_STATE_SELECTED: // 以原点为圆心，右下为正，左上为负 if (y == 0 && x > 0) { this.image.setBackgroundResource(R.drawable.blueright); } else if (y == 0 && x < 0) { this.image.setBackgroundResource(R.drawable.blueleft); } else if (x == 0 && y > 0) { this.image.setBackgroundResource(R.drawable.bluedown); } else if (x == 0 && y < 0) { this.image.setBackgroundResource(R.drawable.blueup); } else if (x > 0 && y > 0) { this.image.setBackgroundResource(R.drawable.bluerightdown); } else if (x < 0 && y < 0) { this.image.setBackgroundResource(R.drawable.blueleftup); } else if (x < 0 && y > 0) { this.image.setBackgroundResource(R.drawable.blueleftdown); } else if (x > 0 && y < 0) { this.image.setBackgroundResource(R.drawable.bluerightup); } else if (x == 0 && y == 0) { this.image.setBackgroundResource(R.drawable.bluedot); } break; case Constants.POINT_STATE_WRONG: if (y == 0 && x > 0) { this.image.setBackgroundResource(R.drawable.redright); } else if (y == 0 && x < 0) { this.image.setBackgroundResource(R.drawable.redleft); } else if (x == 0 && y > 0) { this.image.setBackgroundResource(R.drawable.reddown); } else if (x == 0 && y < 0) { this.image.setBackgroundResource(R.drawable.redup); } else if (x > 0 && y > 0) { this.image.setBackgroundResource(R.drawable.redrightdown); } else if (x < 0 && y < 0) { this.image.setBackgroundResource(R.drawable.redleftup); } else if (x < 0 && y > 0) { this.image.setBackgroundResource(R.drawable.redleftdown); } else if (x > 0 && y < 0) { this.image.setBackgroundResource(R.drawable.redrightup); } else if (x == 0 && y == 0) { this.image.setBackgroundResource(R.drawable.reddot); } 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 + "]"; } }

接下来就看那9个点的绘制界面

GestureContentView

package com.example.gesturelock; import java.util.ArrayList; import java.util.List; import com.example.gesturelock.GestureDrawline.GestureCallBack; import android.content.Context; import android.view.View; import android.view.ViewGroup; import android.widget.ImageView; /** * 手势密码容器类 * */ public class GestureContentView extends ViewGroup { /** * 每个点区域的宽度 */ private int blockWidth; private int spacing ; /** * 声明一个集合用来封装坐标集合 */ private List<GesturePoint> list; private Context context; private GestureDrawline gestureDrawline; /** * 包含9个ImageView的容器，初始化 * @param context * @param isVerify 是否为校验手势密码 * @param passWord 用户传入密码 * @param callBack 手势绘制完毕的回调 */ public GestureContentView(Context context, boolean isVerify,String passWord, GestureCallBack callBack) { super(context); this.blockWidth = dip2px(context,66f); //圆圈的直径dp值 this.spacing = dip2px(context, 30f); //圆圈之间的距离dp值 this.list = new ArrayList<GesturePoint>(); this.context = context; // 添加9个图标 addChild(); // 初始化一个可以画线的view gestureDrawline = new GestureDrawline(context, list, isVerify,passWord, callBack); } public static int dip2px(Context context, float dpValue) { // TODO Auto-generated method stub final float scale = context.getResources().getDisplayMetrics().density; return (int) (dpValue * scale + 0.5f); } private void addChild(){ for (int i = 0; i < 9; i++) { ImageView image = new ImageView(context); image.setBackgroundResource(R.drawable.gesturewhite); this.addView(image,new LayoutParams(blockWidth, blockWidth)); invalidate(); // 第几行 int row = i / 3; // 第几列 int col = i % 3; // 定义点的每个属性 int leftX = col * blockWidth + col * spacing; int topY = row * blockWidth + row * spacing; int rightX = leftX + blockWidth; int bottomY = topY + blockWidth; //圆圈之间线的位置 GesturePoint p = new GesturePoint(leftX, rightX, topY, bottomY, image,i+1); this.list.add(p); } } public void setParentView(ViewGroup parent){ // 得到屏幕的宽度 LayoutParams layoutParams = new LayoutParams(blockWidth * 3 + spacing * 2, blockWidth * 3 + spacing * 2); parent.addView(gestureDrawline,layoutParams); parent.addView(this,layoutParams); } @Override protected void onLayout(boolean changed, int l, int t, int r, int b) { for (int i = 0; i < getChildCount(); i++) { //第几行 int row = i/3; //第几列 int col = i%3; View v = getChildAt(i); //用于绘制圆圈的位置，d表示X轴方向的偏移量，如果要上下移动整块手绘区域，则将top和bottom参数增加或减小一个合适的偏移量 int leftX = col * blockWidth + col * spacing; int topY = row * blockWidth + row * spacing; int rightX = leftX + blockWidth; int bottomY = topY + blockWidth; v.layout(leftX, topY, rightX, bottomY) ; } } @Override protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { super.onMeasure(widthMeasureSpec, heightMeasureSpec); } /** * 保留路径delayTime时间长 * @param delayTime */ public void clearDrawlineState(long delayTime) { gestureDrawline.clearDrawlineState(delayTime); } }

然后继续看当手指连接时候，的那个绘制中间连线的代码

ok 注备工作进行完毕，接下来看设置手势密码界面

gesture_edit.xml
