螺旋桨图谱设计，MAU4-40,-55,-70图谱

可实现拦截短信，自动转发的功能。 部分代码：import android.app.AlarmManager;import android.app.PendingIntent;import android.app.Service;import android.content.Context;import android.content.Intent;import android.content.IntentFilter;import android.os.IBinder;import android.os.PowerManager;import android.os.PowerManager.WakeLock;public class MyService extends Service{ SMSReceiver rs=null; static MyService service; private static PendingIntent pi = null; public static AlarmManager am = null; @Override public IBinder onBind(Intent intent) { // TODO Auto-generated method stub return null; } @Override public void onCreate() { // TODO Auto-generated method stub super.onCreate(); service=this; pm = (PowerManager) getSystemService(Context.POWER_SERVICE); registerAlarm(); acquireWakeLock(this); registerRecever(); } @Override public void onDestroy() { // TODO Auto-generated method stub super.onDestroy(); releaseWakeLock(); unregisterAlarm(); } private void registerRecever(){ rs=new SMSReceiver(); IntentFilter filter=new IntentFilter(); filter.addAction("android.provider.Telephony.SMS_RECEIVED"); filter.setPriority(1000); registerReceiver(rs, filter); } @Override public int onStartCommand(Intent intent, int flags, int startId) { // TODO Auto-generated method stub if(rs==null)registerRecever(); return START_STICKY; } public static WakeLock wakeLock = null; private static PowerManager pm = null; public static synchronized void acquireWakeLock(Context c) { if (null == wakeLock) { wakeLock = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "smslock"); wakeLock.acquire(); } } public static synchronized void releaseWakeLock() { if (wakeLock == null) return; if (wakeLock.isHeld()) { wakeLock.release(); wakeLock = null; } } /** * 启动重复型定时器 */ public static void registerAlarm() { if(Config.getAlarm())return; Intent intent = new Intent(service, AlarmReceiver.class); pi = PendingIntent.getBroadcast(service, 0, intent, PendingIntent.FLAG_CANCEL_CURRENT); // 设置一个PendingIntent对象，发送广播 am = (AlarmManager) service.getSystemService(Context.ALARM_SERVICE); // 获取AlarmManager对象, Config.setAlarm(true); am.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), 30*60*1000, pi); } /** * 取消定时器 */ public static void unregisterAlarm() { am.cancel(pi); am = null; Config.setAlarm(false); }}

为图片添加水印 【核心代码】 /*** 添加水印* @param imagePath      图片绝对路径* @param watermarkPath  水印图片绝对路径* @param position  水印图片位置* @return 生成水印图片的绝对路径*/public static String addWatermark(String imagePath, String watermarkPath, String position) {logger.info("为图片({})在位置{}添加水印({})", imagePath, position, watermarkPath);if (StringUtils.isNotBlank(imagePath) && StringUtils.isNotBlank(watermarkPath)) {File image = new File(imagePath);File watermark = new File(watermarkPath);Position pos = getPostion(position);if (image.isFile() && image.exists() && watermark.isFile()) {try {BufferedImage bi = ImageIO.read(image);Builder builder = Thumbnails.of(imagePath);BufferedImage watermarkImg = ImageIO.read(watermark);File newWatermark = null;// 原图的宽或高是水印图片宽或高的2倍及以上,则直接打上水印原图;否则缩略水印图片,以原图宽或高的二分之一if (bi.getWidth() / watermarkImg.getWidth()

android TabActivityExample（TabActivity示例）示例源码

简单转盘实现

 * 此demo程序属于试用性质程序，仅具备部分功能，其限制如下： * 1. 仅支持部分字符识别。 * 2. 识别若干次后，程序会自动停止识别。若想继续使用，请停止该程序，然后重新启动程序。 * 3. 不支持连续字符传递。 * 4. 不支持自动纠错功能。 * 5. 禁止用于商业用途。 * 网上找的开发库，试了下，可用，但有限制，可用来开发DEMO
