安卓：实现广播接收器ClipboardManager [英] Android : Implement Broadcast Receiver for ClipboardManager

问题描述

我想实现一个监听器，会听，如果一些复制任何东西从任何应用程序。

I want to implement a listener which will listen if some copied any thing from any application.

我听到关于 ClipboardManager.OnPrimaryClipChangedListener（）将听取复制动作，但这不是一个接收器（据我所知）。我有一个示例应用程序，逻辑背后这个应用程序是，开始从系统启动服务，并运行它会听复制操作的服务，但我认为这会耗尽电池。我对吗？

I heard about ClipboardManager.OnPrimaryClipChangedListener() which will listen copy action, but this is not a Receiver (As I understand). I got a sample application, logic behind this application is, start service from system boot and run a service which will listen Copy action, but I think this will drain the battery. Am I right?

那么，如何可以实现广播接收器，可以监听复制操作。的

So how can I implement a Broadcast receiver which can listen Copy action.

推荐答案

下面是监听器：

class ClipboardListener implements ClipboardManager.OnPrimaryClipChangedListener
{
   public void onPrimaryClipChanged()
   {
      // do something useful here with the clipboard
      // use getText() method
   }
}

刚刚注册：

ClipboardManager clipBoard = (ClipboardManager)getSystemService(CLIPBOARD_SERVICE);
clipBoard.addPrimaryClipChangedListener( new ClipboardListener() );
