Question

我在MainActivity中编写代码以重复闹钟，每当我每次重复启动应用程序闹钟时都会重复。但我希望每24小时重复一次。

MainActivity.java

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_home);
    sessionManager = new SessionManager(this);
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    toolbar.setBackgroundColor(getResources().getColor(R.color.black));
    setSupportActionBar(toolbar);
    repeatAlarm();
    }


    private void repeatAlarm() {
    Date when = new Date(System.currentTimeMillis());
    try {
        Intent someIntent = new Intent(getApplicationContext(), MyReciever.class); // intent to be launched
        // note this could be getActivity if you want to launch an activity
        PendingIntent pendingIntent = PendingIntent.getBroadcast(getApplicationContext(), 0, // id, optional
                someIntent, // intent to launch
                PendingIntent.FLAG_CANCEL_CURRENT); // PendintIntent flag
        AlarmManager alarms = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
        alarms.setRepeating(AlarmManager.RTC_WAKEUP, when.getTime(), AlarmManager.INTERVAL_DAY, pendingIntent);
    } catch (Exception e) {
        e.printStackTrace();
    }
}

使用PendingIntent.getService

PendingIntent pendingIntent = PendingIntent.getService(getApplicationContext(), 0, // id, optional
            someIntent, // intent to launch
            PendingIntent.FLAG_CANCEL_CURRENT);

而不是PendingIntent.getBroadcast

PendingIntent pendingIntent = PendingIntent.getBroadcast(getApplicationContext(), 0, // id, optional
            someIntent, // intent to launch
            PendingIntent.FLAG_CANCEL_CURRENT);
