android– 如何使用意图服务与服务更新UI进行多个图像上传

概述我是android开发人员.当我使用intent服务在后台发送多个图像时,我有面子问题ANR.我在Resume()方法上有调用服务.我在逐步图像上传完成时有更新UI.我的所有代码都在服务中.但是我不明白为什么我的UI挂起.我已经为UpdateUI创建了ResultReceiver类.请告诉我我在做什么问题.publicc

我是android开发人员.当我使用intent服务在后台发送多个图像时,我有面子问题ANR.我在Resume()方法上有调用服务.我在逐步图像上传完成时有更新UI.我的所有代码都在服务中.但是我不明白为什么我的UI挂起.我已经为Update UI创建了ResultReceiver类.请告诉我我在做什么问题.

解决方法:

有很多方法可以将更多图像上传到服务器..一个可能包括两个库：apache-mime4j-0.6.jar和httpmime-4.0.1.jar ..之后创建你的java主代码：

现在你的布局：

<?xml version="1.0" enCoding="utf-8"?><linearLayout     xmlns:androID="http://schemas.androID.com/apk/res/androID"    androID:orIEntation="vertical"    androID:layout_wIDth="fill_parent"    androID:layout_height="fill_parent"    ><TextVIEw    androID:layout_wIDth="fill_parent"    androID:layout_height="wrap_content"    androID:text="Multiple file Upload from CoderzHeaven"    /><button    androID:ID="@+ID/button01"    androID:layout_wIDth="wrap_content"    androID:layout_height="wrap_content"    androID:text="Get First file"></button><button    androID:ID="@+ID/button02"    androID:layout_wIDth="wrap_content"    androID:layout_height="wrap_content"    androID:text="Get Second file"></button><button    androID:ID="@+ID/upload"    androID:layout_wIDth="wrap_content"    androID:layout_height="wrap_content"    androID:text="Start Upload"></button><TextVIEw    androID:ID="@+ID/tv"    androID:layout_wIDth="fill_parent"    androID:layout_height="wrap_content"    androID:text="Selected file path : "    /><TextVIEw    androID:ID="@+ID/res"   androID:layout_wIDth="fill_parent"   androID:layout_height="wrap_content"   androID:text=""   /></linearLayout>

当然,在您的清单中包含互联网权限：

<uses-permission androID:name="androID.permission.INTERNET" />

瞧.无论如何,我在我的情况下遵循这个例子：http://www.coderzheaven.com/2011/08/16/how-to-upload-multiple-files-in-one-request-along-with-other-string-parameters-in-android/尝试看那里..有4种方法上传多个文件.看看你喜欢哪个
