Android自定義UI手勢密碼終結版
更新時間：2016年10月31日 15:07:22 作者：Saflyer
這篇文章主要為大家詳細介紹了Android自定義UI手勢密碼,具有一定的參考價值，感興趣的小伙伴們可以參考一下
之前寫過3篇手勢密碼的demo,不過沒有集成到真實的企業(yè)項目中，這幾天正好領到一個手勢密碼項目，昨天剛好弄完，今天抽空整理下，目前還沒有完善，有一些地方需要更改，不過基本的流程都可以跑通了。
源碼下載地址：http://xiazai.jb51.net/201610/yuanma/AndroidGestureLock(jb51.net).rar
先看主界面的入口把、里面有2個button(一個是設置手勢密碼、一個是校驗手勢密碼)
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="設置" /> <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="校驗" /> </RelativeLayout>
在看主界面的代碼把
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;
}
}
}
想了想還是先貼數(shù)據(jù)庫把---就是存放手勢密碼、以及還可以輸入的手勢密碼次數(shù)
publicSQLiteOpenHelper
package com.example.gesturelock;

return "";

接下里再看工具類把--就是輸入的手勢密碼簡單MD5加密、以及屏幕尺寸工具類
/**

*/
package com.example.gesturelock;
import android.content.Context;
import android.view.WindowManager;
public class AppUtil {

* @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();
}
}
一步步來，接下來看bean類，就是每個圓點的屬性
