Question

我的布局中有两个FloatingActionButton。两者都以相同的方式附加到CoordinatorLayout。

void StartAlarm(int day, int hour, int minutes) {
    calendar = Calendar.getInstance();
    calendar.set(Calendar.DAY_OF_MONTH, day);
    calendar.set(Calendar.HOUR_OF_DAY, hour);
    calendar.set(Calendar.MINUTE, minutes);
    calendar.set(Calendar.SECOND, 0);

    Random r = new Random();
    int rcode = r.nextInt(10000 - 50) + 50;
    rcodeAlarm.add(String.valueOf(rcode));

    Intent myIntent = new Intent(Time.this, MyReceiver.class);
    pendingIntent = PendingIntent.getBroadcast(Time.this, rcode, myIntent, 0);

    AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
    alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent);
    timeAlarm.add(String.valueOf(calendar.getTimeInMillis()));
}

然而，当我展示一个小吃店时，只有底部的FAB上下移动。

        app:headerLayout="@layout/navigation_header"

</android.support.v4.widget.DrawerLayout>

如何使两者都移动？

Answer 1

我找到的解决方案是再次实现FloatingActionButton行为并在FAB中明确设置它。

关于如何实现默认行为，BaseLab的人员有一篇好文章here，其匹配的GitHub repo。

创建自己的此类行为重新实现后，只需将其设置在布局文件中，如下所示：

Snackbar.make(mCoordinator, "FAB pressed", Snackbar.LENGTH_LONG).show();

现在两个按钮将在你的SnackBar出现时移动！
