长按Android

在我的自定义视图中检测长按时遇到问题.

这是与此问题相关的代码

final GestureDetector gestureDetector = new GestureDetector(new GestureDetector.SimpleOnGestureListener() {
    public void onLongPress(MotionEvent e) {
        Log.e("dbg_msg", "onLongPress");
    }
});

public boolean onTouchEvent(MotionEvent event) {
    return gestureDetector.onTouchEvent(event);
};

长按此代码可检测每一次(短)点击.

当我把这个代码放在从Activity继承的类中时,它可以工作.

那为什么它不能在自定义视图中工作？

Symfony2无法加载bundle

我正在尝试在新的Symfony2项目中使用我自己的bundle.我创建了项目,然后使用composer安装了所有必需的包.

这是我的项目的composer.json文件

在 iframe 中拖放

我正在尝试制作一个网络应用程序，允许用户在 iframe 元素中拖动 div。

这是我当前在 index.html 中的代码：

<script type="text/javascript" src="http://code.jquery.com/jquery.min.js"></script>
<script>
    function onDrag(event){
        event.dataTransfer.setData('Text', 'Some content');
    }
</script>
<div id="items">
    <ul>
        <li><div draggable="true" ondrag="onDrag(event)">Content1</div></li>
        <li><div draggable="true" ondrag="onDrag(event)">Content2</div></li>
    </ul>
</div>
<iframe id="box" src="box.html">
</iframe>

这是我来自 box.html 的代码：

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="utf-8" />
    <title></title>
    <script>    
        function onDrop(event){
            event.target.innerHTML += event.dataTransfer.getData('Text');
            alert('Ok!');
        }
        function onDragOver(ev){
            ev.preventDefault();
        }
    </script>
</head>
<body ondragover="onDragOver(event)" ondrop="onDrop(event)">
</body>
</html>

拖动有效，我什至从 onDrop 函数收到该警报，但event.dataTransfer.getData('Text')返回空字符串，我不知道为什么。

提前致谢
