如何在android 2.2中实现拖放？
我正在尝试开发一个android应用程序，用户应该能够将图像从网格的一个单元格拖动到另一个单元格。为了实现这一点，我需要Android 3.0中引入的拖放API，但我的应用程序应该在Android 2.2中运行。那么，有没有办法通过触摸事件来实现这一点？如果是，那么请提供一些代码片段或任何简要描述它的链接 触地事件：触地->锁定项目触地点 按照触摸方向->更新位置 触摸事件：触摸->锁定项目位置如何在android 2.2中实现拖放？,android,android-layout,drag-and-drop,Android,Android Layout,Drag And Drop,我正在尝试开发一个android应用程序，用户应该能够将图像从网格的一个单元格拖动到另一个单元格。为了实现这一点，我需要Android 3.0中引入的拖放API，但我的应用程序应该在Android 2.2中运行。那么，有没有办法通过触摸事件来实现这一点？如果是，那么请提供一些代码片段或任何简要描述它的链接 触地事件：触地->锁定项目触地点 按照触摸方向->更新位置 触摸事件：触摸->锁定项目位置 大家好，在安卓2.2中进行了长时间的拖放操作，获得了成功 在这里，我给出了成功的代码。我的主要课程在

我从MobileArchyWidget获得了一些灵感，但我改进了一些东西 正如你们所看到的，我使用PopupWindow创建DrageEffect，甚至我从可拖动对象克隆了可视部分。此外，我不必使用布局的任何部分。简单地将DragDropManager.class放入项目中。不需要改变。没有额外资源。如果一个区域完全/部分覆盖另一个区域，则可以同时命中更多区域。您可以拖动至少是视图的任何内容。我会在活动窗口上切换回调，这样当您拖动某个对象时，其他任何对象都无法访问事件。在这个解决方案中，您从未从DragTable中失去焦点，而且当您从屏幕上拿起手指时，DragDrop将自动结束（活动重新获得回调的控制权） 我没有时间给你展示所有的组合。但正如你所看到的那样 只有一个DropZoneListener。您可以使用更多，但请记住，所有侦听器都会被调用，所有更改的拖动状态都会发送给每个侦听器 例如： 降落区D1、D2； 听者L1，L2 如果D1或D2发生变化 L1（Dx）和L2（Dx） 如果D1和D2发生变化 L1（D1，D2）和L2（D1，D2） 但它是好的，因为你知道如果它掉在别的地方。我忘记了DragItem是对象，所以当删除它时，必须解析对象的类型。但这也很好，因为当您使用片段时，您永远不知道可以拖动哪种类型的数据 在我的解决方案中，我检查对象类型级别。如果dragzone不支持对象，您将知道。view.setOnTouchListener（new view.OnTouchListener（）{
)xan请简要解释一下。或者你能分享一个链接来解释这一点吗？这只是解决这个问题的一般方法。按照@himanshu给出的链接进行操作。你能分享一个片段来解释如何在触摸点上锁定物品以及如何遵循触摸方向吗？这是我见过的最傲慢的回答。如果你ad尽一切努力解释你所写的内容，同意@azfar，但不敢相信Chandra Sekhar甚至将其标记为正确。下面的链接将帮助你解决你的问题…可能是Zala的重复，事实上我是从那里得到我的解决方案的。所以我还没有测试你的代码。Zala请不要在我的博客上发表任何与此网站相关的评论。你可以在这里发表评论。我会在这里回复你。如果你对我的博客主题有任何问题，那么你可以在那里发表评论。我尝试了你的例子，在第一次拖放后它挂在那里，你有任何错误修复吗？嗯，没有，我不能。很久以前。它在2.2 Froyo上确实有效。但在更新的版本上似乎没有。想法是capture窗口回调将MouseEvent从活动分派到Touch视图，并将对象bitmat缓冲区复制到PopupWindow中，其中x，y由mousemove更改。
