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

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

 });
// 设置手势解锁显示到哪个布局里面
