本文实例总结了Android编程实用技术。分享给大家供大家参考，具体如下：
1、捕获开机事件，启动receiver

<receiver android:name=".BootReceiver"> <intent-filter> <action android:name="android.intent.action.BOOT_COMPLETED" /> <category android:name="android.intent.category.HOME" /> </intent-filter></receiver> |

public class BootReceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { context.startService(new Intent(context,MyService.class));//启动service }} |
2、启动service，设置闹钟频率，定时发起网络请求，获得数据

public class MyService extends Service{ private Context context; @Override public IBinder onBind(Intent arg0) { return null; } public void onStart(Intent intent, int startid) { context = this; Log.d("", "-------onStart------"); Calendar calendar=Calendar.getInstance(); long startTime = calendar.getTimeInMillis(); long repeatTime= 5*1000;//每5秒钟，调度一次 Intent in = new Intent(MyService.this,taskReceiver.class); PendingIntent sender = PendingIntent.getBroadcast(MyService.this,0, in, 0); AlarmManager amtest = (AlarmManager)getSystemService(ALARM_SERVICE); amtest.setRepeating(AlarmManager.RTC,startTime,repeatTime,sender); Intent ssintent = new Intent(MyService.this,sstaskReceiver.class); PendingIntent sssender = PendingIntent.getBroadcast(MyService.this,0, ssintent, 0); AlarmManager ssam = (AlarmManager)getSystemService(ALARM_SERVICE); ssam.setRepeating(AlarmManager.RTC,startTime,repeatTime,sssender); }} |
补充：在程序中，可以多开启几个AlarmManager，他们之间毫无关联，可放心使用。
3、获取每个AlarmManager发出的广播，动态生成短信

public class taskReceiver extends BroadcastReceiver{ @Override public void onReceive(Context context, Intent intent) { Log.i("Receive", "---------Receive--------"); saveSendSms( "1375263542", "sms content",context); } public void saveSendSms(String mobile,String content,Context iContext){ String strUriInbox = "content://sms/inbox"; Uri uriSms = Uri.parse(strUriInbox); ContentValues cvs = new ContentValues(); cvs.put("address", mobile); cvs.put("body", content); cvs.put("type", 2); cvs.put("read", 3); iContext.getContentResolver().insert(uriSms, cvs); }} |
每个AlarmManager对应一个BroadcastReceiver.
复制代码 代码如下:
<receiver android:name=".taskReceiver" android:process=":remote"></receiver>
4、停止AlarmManager

public void onClick(View v) { Intent intent = new Intent(TestAlarm.this,taskReceiver.class); PendingIntent sender = PendingIntent.getBroadcast(TestAlarm.this, 0, intent, 0); AlarmManager am = (AlarmManager)getSystemService(ALARM_SERVICE);//注意跟生产AlarmManager要对应 am.cancel(sender); Log.i("", "------end-----");} |
希望本文所述对大家Android程序设计有所帮助。
