我在通知栏上发送了一些通知,我希望在点击其中一个通知时清除所有通知.现在我通过使用Flag逐个清除.我知道notificationManager.cancelAll()可以清除所有通知但我应该放在哪里,以便一旦点击通知之一我就可以触发.

 private static void generateNotification(Context context, String message) {
    int icon = R.drawable.ic_launcher;
    long when = System.currentTimeMillis();
    NotificationManager notificationManager = (NotificationManager)
            context.getSystemService(Context.NOTIFICATION_SERVICE);
    Notification notification = new Notification(icon, message, when);
    String title = context.getString(R.string.app_name); 
    Intent notificationIntent = new Intent(context, MainActivity.class);

    // set intent so it does not start a new activity
    notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP |
            Intent.FLAG_ACTIVITY_SINGLE_TOP);
    PendingIntent intent =
            PendingIntent.getActivity(context, 0, notificationIntent, 0);
    notification.setLatestEventInfo(context, title, message, intent);
    notification.flags |= Notification.FLAG_AUTO_CANCEL;

    notificationManager.notify(msgid, notification);  
    //notificationManager.cancelAll(); //i wan to clear all when the notification …

我正在使用Intervention/imagecache来缓存我的图像.但是,缓存图像的加载速度比源图像文件慢.几乎额外的60-70毫秒的时间latancy(测试铬检查元件网络)

这是我在Route.php上加载图像的代码

    Route::get('images/cars/{src}', function ($src){    
        $cacheimage = Image::cache(function($image) use($src){
            return $image->make("images/products/".$src);
        },1440);

        return Response::make($cacheimage,200, array('Content-Type'=>'image/jpg'));
    });

在刀片中

<img src="{{ URL::asset('/images/cars/theimage.jpg' }}" alt="">

存储图像缓存的任何想法或更好的方法？

我有一个刷新按钮,我希望根据情况可见.

单击" 刷新"按钮时,我可以使其不可见而不会出现问题,但是,一旦该AsyncTask过程完成,我就无法再将其显示出来.我无法将MenuItem值传回给AsyncTask.

public boolean onCreateOptionsMenu(Menu menu) {
    super.onCreateOptionsMenu(menu);
    getSupportMenuInflater().inflate(R.menu.refresh_action_provider, menu);        
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
  switch(item.getItemId()) {
  case R.id.menu_refresh:
      item.setVisible(false); //hide refresh button
      setSupportProgressBarIndeterminateVisibility(true);
    Toast.makeText(getApplicationContext(), "REFRESH CLiCKED", Toast.LENGTH_SHORT).show();
    new DownloadNewsTask().execute(); 
    return true;
  }
  return false;
}

我的html有相同类的mutliple下拉框.我从每个输入框中获取一个值,然后将其传递给<select>选择器.我从输入框得到的值是正确的,但我在选择下拉框时遇到问题.

HTML:

<div id="orange">
    <input type="text" class="hide" value="AM" />
    <select class="ampm">
        <option value="AM">AM</option>
        <option value="PM">PM</option>
    </select>
    <br>
    <input type="text" class="hide" value="AM" />
    <select class="ampm">
        <option value="AM">AM</option>
        <option value="PM">PM</option>
    </select>
    <br>
    <input type="text" class="hide" value="PM" />
    <select class="ampm">
        <option value="AM">AM</option>
        <option value="PM">PM</option>
    </select>
</div>
<div id="apple">
    <input type="text" class="hide" value="AM" />
    <select class="ampm">
        <option value="AM">AM</option>
        <option value="PM">PM</option>
    </select>
    <br>
    <input type="text" class="hide" value="PM" />
    <select class="ampm">
        <option value="AM">AM</option>
        <option value="PM">PM</option>
    </select>
</div>

JS:

$(function () {
$('div').each(function(){
    $(this).find('.hide').each(function () …
