Android自定义闹钟功能

Android闹钟alarmManager+PendingIntent的使用方法,供大家参考,具体内容如下

这次给大家分享两种闹钟:

第一种是当到达闹钟时间后执行一次相应的操作

alarmManager.set(AlarmManager.RTC_WAKEUP,c.getTimeInMillis(),pendingIntent);

第二种是当到达闹钟时间后每隔一段时间执行操作

alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,c.getTimeInMillis(),5000, pendingIntent);

下面看效果图:

设置两种闹钟

选择闹钟时间

闹钟一到打开一个界面

下面看代码:

public class Alarm2Activity extends AppCompatActivity {

private AlarmManager alarmManager;

private PendingIntent pendingIntent;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_alarm2);

//实例化闹钟个管理器

alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);

}

//设置闹钟(只响一次)

public void startAlarmOne(View view){

//获取当前系统的时间

Calendar calendar=Calendar.getInstance();

int hour=calendar.get(Calendar.HOUR_OF_DAY);

int minute=calendar.get(Calendar.MINUTE);

//弹出时间对话框(选择时间)

TimePickerDialog timePickerDialog=new TimePickerDialog(this, new TimePickerDialog.OnTimeSetListener() {

@Override

public void onTimeSet(TimePicker timePicker, int i, int i1) {

//获取当前系统的时间

Calendar c=Calendar.getInstance();

c.set(Calendar.HOUR_OF_DAY,i);

c.set(Calendar.MINUTE,i1);

//打开一个Activity

Intent intent=new Intent();

intent.setAction("com.example.myandroid_27.ALARM");

PendingIntent pendingIntent= PendingIntent.getBroadcast(Alarm2Activity.this,0x101,intent,0);

//设置闹钟

alarmManager.set(AlarmManager.RTC_WAKEUP,c.getTimeInMillis(),pendingIntent);

}

},hour,minute,true);

timePickerDialog.show();

}

//设置闹钟(在多长时间后闹钟响然后继续计时)

public void startAlarmTwo(View view){

//获取当前系统的时间

Calendar calendar=Calendar.getInstance();

int h=calendar.get(Calendar.HOUR_OF_DAY);

int m=calendar.get(Calendar.MINUTE);

//弹出时间对话框(选择时间)

TimePickerDialog timePickerDialog=new TimePickerDialog(this, new TimePickerDialog.OnTimeSetListener() {

@Override

public void onTimeSet(TimePicker timePicker, int i, int i1) {

//获取选择的闹钟时间

Calendar c=Calendar.getInstance();

c.set(Calendar.HOUR_OF_DAY,i);

c.set(Calendar.MINUTE,i1);

//打开一个Activity

Intent intent=new Intent();

intent.setAction("com.example.myandroid_27.ALARM");

pendingIntent = PendingIntent.getBroadcast(Alarm2Activity.this,0x102,intent,0);

//闹钟什么时候继续执行

alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,c.getTimeInMillis(),5000, pendingIntent);

}

},h,m,true);

timePickerDialog.show();

}

//关闭周期闹钟

public void startAlarmThree(View view){

alarmManager.cancel(pendingIntent);

}

}
