Java代码
TelephonyManager tm = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);
String imei = tm.getDeviceId();
String tel = tm.getLine1Number();
TelephonyManager tm = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);
String imei = tm.getDeviceId();
String tel = tm.getLine1Number();
看来，android的确加速了j2me的消亡。
Android 振动器
总感觉手机上的振动器没有多大用处(当然静音模式下的振铃很有用)，但还是顺带着说一下吧，只有两行代码：
1、获取振动服务的实例
Vibrator vibrator = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE);
2、设置振动时长，单位当然也是ms
vibrator.vibrate(1000);
如果你觉得这样过去单调的话，可以设个节奏：
vibrator.vibrate(new long[]{10, 100, 20, 200}, -1);
两个参数，习惯告诉我第一个是节奏，第二个是重复次数，可事实并没有这么简单，我翻译不好，大家还是看原文吧：
Java代码
public void vibrate (long[] pattern, int repeat)
pattern: an array of longs of times to turn the vibrator on or off.
repeat: the index into pattern at which to repeat, or -1 if you don't want to repeat.
public void vibrate (long[] pattern, int repeat)
pattern: an array of longs of times to turn the vibrator on or off.
repeat: the index into pattern at which to repeat, or -1 if you don't want to repeat.
google喜欢弄些技巧，我却觉得这里有点弄巧成拙了。
Android 闹钟
最近看了一下Android的闹钟管理类(AlarmManager)，真不错误，强大又简单，代码如下：
1、建立一个AlarmReceiver继承入BroadcastReceiver，并在AndroidManifest.xml声明
Java代码
public static class AlarmReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
Toast.makeText(context, "闹钟提示：时间到!", Toast.LENGTH_LONG).show();
}
}
public static class AlarmReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
Toast.makeText(context, "闹钟提示：时间到!", Toast.LENGTH_LONG).show();
}
}
2、建立Intent和PendingIntent，来调用目标组件。
Java代码
Intent intent = new Intent(this, AlarmReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, intent, 0);
Intent intent = new Intent(this, AlarmReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, intent, 0);
3、设置闹钟
获取闹钟管理的实例：
Java代码
AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
设置单次闹钟：
Java代码
alarmManager.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + (5*1000), pendingIntent);
alarmManager.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + (5*1000), pendingIntent);
设置周期闹钟：
Java代码
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + (10*1000), (24*60*60*1000), pendingIntent);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + (10*1000), (24*60*60*1000), pendingIntent);
搞定!当然这里闹钟的响应处理只是用的文字，你可以播放声音，或都用更复杂的一系统通知，在这里你就是上帝，一切由你做主。
