Android 使用意向过滤器发送数据
谷歌play这样的市场是如何与意向过滤器协同工作的？我对intent filter略知一二，但不知道如何使用它发送数据？如何使用相关应用程序数据启动活动？是否使用广播接收器？ 当我浏览应用程序X并希望下载它时，我的已安装市场将通过“使用操作完成”对话框中的X应用程序信息启动。我不知道如何导航到相关页面？ 有人能解释一下或提供一些例子吗？ 感谢您的意向过滤器Ex: 在下面的代码中，使用将数据发送到另一个活动 活动1：Android 使用意向过滤器发送数据,android,android-intent,broadcastreceiver,intentfilter,Android,Android Intent,Broadcastreceiver,Intentfilter,谷歌play这样的市场是如何与意向过滤器协同工作的？我对intent filter略知一二，但不知道如何使用它发送数据？如何使用相关应用程序数据启动活动？是否使用广播接收器？ 当我浏览应用程序X并希望下载它时，我的已安装市场将通过“使用操作完成”对话框中的X应用程序信息启动。我不知道如何导航到相关页面？ 有人能解释一下或提供一些例子吗？ 感谢您的意向过滤器Ex: 在下面的代码中，使用将数据发送到另一个活动 活动1： Intent myintent=new Intent(this,MyList

在清单的活动标记中添加意图过滤器，这允许其他应用在请求相应操作时转到同一活动：

谢谢回复，但我想将数据从浏览器发送到我的应用程序。让我再解释一下：考虑你导航到Viver主页，你想下载它，当触摸到ViBER按钮，使用对话框出现完整的动作，当敲击一个市场，如谷歌游戏，你启动谷歌播放应用与相关的Viver页面的细节。我不知道怎么做？我理解你的想法。这是可能的。我正在将我的应用程序之间的图像上载到网站。我正在使用php Web服务。我正在获取代码。为了您的方便，请参考此代码。谢谢您的回复，我得到的是空的。如何从浏览器中检测它？我不知道你的代码是什么意思。你能提供更多的细节吗？这和你从意图过滤器抓到的动作是一样的吗？以下是您可以从其他应用程序捕获的操作列表：sdk/platforms/android-x/data/broadcast_actions.txt如何从浏览器检测它？如果浏览器使用startActivity调用您的应用程序，则无法执行此操作。但是，如果浏览器使用getCallingActivity使用startActivityForResult调用您的应用程序，您就可以得到它。如果您只需要包名，那么就有getCallingPackage
