之前写过3篇的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。

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
<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" tools:context="com.example.gesturelock.mainactivity" > <button android:id="@+id/setting" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignparentleft="true" android:layout_alignparenttop="true" android:text="设置" /> <button android:id="@+id/verify" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignparenttop="true" android:layout_torightof="@+id/setting" android:text="校验" /> </relativelayout>
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;

{
super(context, name, null, version);
}
@override
public void oncreate(sqlitedatabase db)
{
string sqlpass = "create table " + "gesture_password"+ "("

db.execsql(sqlpass);
}
@override

}
}
/**

try {

if (cursor != null && cursor.getcount()>0) {
return true;
}else {
return false;
}
} catch (exception e) {

finally{

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;

public class apputil {

public static int[] getscreendispaly(context context) {

@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
