如何仅过滤Android图库中的图像和视频？

例如:

    intent.setType("image/*");   //returns only images
    intent.setType("video/*");   //returns only videos
    intent.setType("*/*");       //returns all videos,images, audios,contacts,etc..

我只想要图像和视频.我怎么能做到这一点？

好的,让我修改问题并使其更容易.我希望你能为我找到解决方案.两个警报应该同时安排,这不会发生在这里.我甚至使用唯一的请求代码来处理待处理的意图.请帮帮我.....

//单击"侦听器"

private OnClickListener mOneShotListener = new OnClickListener() {
    public void onClick(View v) {

        Intent intent = new Intent(AlarmController.this, OneShotAlarm.class);
        PendingIntent sender = PendingIntent.getBroadcast(AlarmController.this,0, intent, 0);
        //I even tried sender = PendingIntent.getBroadcast(AlarmController.this,0, intent, PendinIntent.FLAG_UPDATE_CURRENT);


        //the alarm to go off 30 seconds from now.

        Calendar calendar = Calendar.getInstance();
        calendar.setTimeInMillis(System.currentTimeMillis());
        calendar.add(Calendar.SECOND, 30);

        // Schedule the alarm!

        AlarmManager am = (AlarmManager)getSystemService(ALARM_SERVICE);
        am.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), sender);

        //adds 2 minutes to the time

        calendar.add(Calendar.MINUTE, 2);

        sender = PendingIntent.getBroadcast(AlarmController.this,1, intent,0);
        am.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), sender2);
    }
};
