Android自定义闹钟

这次给大家分享两种闹钟：

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

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

下面看效果图：

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);
}
}
