Android 通过点击聊天头（小部件）保存网络/其他应用程序中的文本选择

我试图做的是类似于Diigo的复制泡沫——一个类似Facebook的聊天头。从现在起称为Chathead，它基本上允许用户在外部应用程序/webb浏览器中选择文本，并通过单击Chathead将所选文本保存到应用程序的记事本活动中：

流程： 1.从另一个应用程序通过共享功能启动小部件

小部件显示1个按钮。单击按钮启动聊天室并关闭第一个小部件

用户现在可以选择一个文本字符串，然后单击聊天头。这将做两件事：

a更改聊天头的文本。因此，例如，如果用户选择了et red ball，聊天头现在将显示一个标题，称为red ball

b将文本字符串保存到Diigo中我的应用程序的另一个活动中，它将是Diio应用程序中的记事本。我还没有创建这个活动，因此下面没有示例代码

当扔掉聊天头时，就像Facebook聊天头一样。聊天室被摧毁/关闭

到目前为止，我掌握的情况如下：

ANDROIDMANIFEST.XML将“我的应用”添加到用户可以共享其他应用内容的应用列表中。此时，共享到我的应用程序将打开一个正常的活动，而不是小部件。此活动显示一个按钮，单击该按钮将启动聊天室。为了启动聊天室，我还在清单中定义了一个服务

<activity android:name=".NewOrExistingObjectPicker"
        android:label="@string/app_name"
        android:screenOrientation="portrait">
        <intent-filter>
            <action android:name="android.intent.action.SEND" />
            <data android:mimeType="text/plain" />
        </intent-filter>
    </activity>

   <service
        android:name="kowkeekowks.trackabo.Flyer"
        android:exported="true">
    <intent-filter>
        <action android:name="android.intent.action.SEND" />
        <data android:mimeType="text/plain" />
    </intent-filter>
   </service>

java这是我的聊天室。问题：是否可能有一个按钮，用户可以移动和点击-即对onTouch和onClick都有响应？现在我有了连接到WindowManager本身的onTouch方法，我需要在按钮的背景中有一个较大的图像，以便将聊天头拖动到不同的位置
