Android常用功能实例 如IMEI号

核心提示：Java代码TelephonyManager tm = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);String imei = tm.getDeviceId();String tel = tm.getLine1Number(

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();
