Android自定义UI手势密码改进版源码下载

在之前文章的铺垫下，再为大家分享一篇：Android手势密码，附源码下载，不要错过。

源码下载：http://xiazai.jb51.net/201610/yuanma/androidLock(jb51.net).rar

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 }

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" > <RelativeLayout android: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" > <TextView android: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> <LinearLayout android: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" > <TextView android: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> <FrameLayout android: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> <TextView android: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>

再看来绘制密码的类

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" > <LinearLayout android: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" > <TextView android: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> <FrameLayout android:id="@+id/gesture_container" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@id/gesture_tip_layout" > </FrameLayout> </RelativeLayout>

验证密码的代码实现类
GestureVerifyActivity
