我想每过一分钟就做点什么，例如当时间从 10:38 变为 10:39 时，我想做点什么。

做这个的最好方式是什么？

为此使用AlarmManager。

void startSchedulerAlarm() {
    int oneMinute = 1 * (60 * 1000); //Trigger Every 1 Minute
    AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
    Intent intent = new Intent(context, AlarmReceiver.class);
    intent.setAction(AlarmReceiver.alaramIntent);
    PendingIntent alarmIntent = PendingIntent.getBroadcast(context, AlarmReceiver.alarmIntentCode, intent, PendingIntent.FLAG_UPDATE_CURRENT);
    alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), oneMinute, alarmIntent);

}

void stopSchedulerAlarm() {
    AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
    Intent intent = new Intent(context, AlarmReceiver.class);
    intent.setAction(AlarmReceiver.alaramIntent);
    PendingIntent alarmIntent = PendingIntent.getBroadcast(context, AlarmReceiver.alarmIntentCode, intent, PendingIntent.FLAG_UPDATE_CURRENT);
    alarmManager.cancel(alarmIntent);
}

在 Manifest 中为您的警报创建一个接收器：

    <receiver       
        android:name="{YOUR_PACKAGE_NAME}.AlarmReceiver"
        android:enabled="true"
        android:process=":remote">
        <intent-filter>
            <action android:name="{YOUR_PACKAGE_NAME}.alarmIntent"/>
        </intent-filter>
    </receiver>

公共类 AlarmReceiver 扩展 BroadcastReceiver {

public static final String alaramIntent = "{YOUR_PACKAGE_NAME}.alarmIntent";
public static final int alarmIntentCode = 000054310;

private String TAG = AlarmReceiver.class.getSimpleName();

   @Override
   public void onReceive(Context context, Intent intent) {
        //Do something Here
   }
}

您需要通过广播接收器收听 TIME_TICK

IntentFilter timeTickIntentFilter = new IntentFilter(Intent.ACTION_TIME_TICK);
registerReceiver(YourReceiver, timeTickIntentFilter);

让服务在后台运行，持续检查指定时间，假设您想在晚上 10:00 时将手机调至静音模式。因此服务应继续检查时间是否为晚上 10:00，如果是，则执行代码以将手机设置为静音模式
