我使用SQLite設置了多個警報，但是當我設置時鐘時，只有一個警報是我設置的最後一個警報。我怎樣才能解決這個問題？使用sqlite數據庫設置多個警報，但只剩下一個警報
public class alert extends Activity{
DatePicker pickerDate;
TimePicker pickerTime;
Button buttonSetAlarm;
Button insertButton;`enter code here`
TextView info;

Calendar now = Calendar.getInstance();
pickerDate.init(
now.get(Calendar.YEAR),
now.get(Calendar.MONTH),
now.get(Calendar.DAY_OF_MONTH),
null);
pickerTime.setCurrentHour(now.get(Calendar.HOUR_OF_DAY));
pickerTime.setCurrentMinute(now.get(Calendar.MINUTE));
buttonSetAlarm = (Button)findViewById(R.id.setalarm);
buttonSetAlarm.setOnClickListener(new OnClickListener(){

//dbAlarm.addNewAlarm(new dalHelper_alarm(pickerTime.getCurrentHour(),pickerTime.getCurrentMinute(),cal.getTime().toString()));
if(cal.compareTo(current) <= 0){
Toast.makeText(getApplicationContext(),
"Invalid Date/Time",
Toast.LENGTH_LONG).show();
}else{

}
