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。
