我要注册一个BroadcastReceiver,并在收到广播时传递一个我想要显示的id。
我想要做的是访问特定实例(即警报响起时)的数据库条目,这就是我通过意图传递id的原因
View.OnClickListener saveHandler = new View.OnClickListener() {
@Override
public void onClick(View v) {
Log.d("Insert: ", "Inserting ..");
mContext = getApplicationContext();
objalarmManger = (AlarmManager) getSystemService(ALARM_SERVICE);
Intent broadcastIntent = new Intent(mContext,
MyBroadCastReceiver.class);
broadcastIntent.putExtra("id",22);
PendingIntent objPI = PendingIntent.getBroadcast(mContext, 0,
broadcastIntent, 0);
Calendar objC = Calendar.getInstance();
objC.set(yearData, monthData, dayData, hour, min);
objalarmManger.set(AlarmManager.RTC_WAKEUP, objC.getTimeInMillis(),
objPI);
}
};
广播接收器代码是
public class MyBroadCastReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context arg0, Intent arg1) {
int id = arg1.getIntExtra("id", 0);
Toast.makeText(arg0, id, Toast.LENGTH_LONG).show();
Log.d("Received", id + "");
}
}
我无法看到任何log cat entiers,代码实现中是否有任何错误。 任何帮助将不胜感激:)
