由于提前
推荐答案
基本上你不能用一个ListView与手机应用程序部件。这不是一个受支持的View（适用于支持的人的名单，看看这里 ）。
Basically you can't use a ListView with an app widget on phones. It's not a supported View (for a list of supported ones, look here).
真正的故事是一个比较复杂一点，有两个例外情况：
The true story is a bit more complicated, there are two exceptions to this rule:
的首页的，你可以用它在Honeycomb（Android 3.0以上版本），不过目前只有那粒。我从来没有这个工作，从短检索，文档似乎有点缺乏的，发现几乎没有任何的这个（这是的下的Android 3.0平台API概述应用小工具 - 也有链接到几样）
First, you can use it on Honeycomb (Android 3.0+), but thats only tablets at the moment. I never have worked with this and from a short search, the doc seems a bit lacking here, found hardly any evidence of this (it's noted inside the Android 3.0 Platform API overview under "App widgets" - there are also links to a few samples).
的二的，一些替代发射器不支持的ListView。我不知道到底是哪些，继承人在Android市场从纯使者部件说明报价：
Second, some alternative launchers do support the ListView. I don't know exactly which ones, heres a quote from the "Pure messenger widget" description in the Android market:
滚动部件用最另类的发射像ADW，LiveHome，
GO桌面或的LauncherPro
Scrollable widget with most alternative launchers like ADW, LiveHome, Go Launcher Ex or LauncherPro
这意味着你可以从市场安装大多数自定义发射器。
它不包括专有发射器支持列表视图在一个未公开的方式 - 例如， HTC Sense的。
That means most custom launchers that you can install from the Market. It does not include proprietary launchers which support ListViews in an undocumented manner - e.g. HTC Sense.
我不知道如果你能做到的ALT-发射了一些兼容性测试。您可以使用资源说明符蜂窝设备从静止分裂，但即使如此，你仍然是从厂家的许多香草设备或默认的发射器不兼容。
I'm not sure if you can do some compatibility testing for alt-launchers. You may use res specifiers to split Honeycomb devices from the rest, but even then you are still incompatible with many vanilla devices or default launchers from the manufacturers.
要总结：它是目前列表视图一个非常糟糕的情况。
To sum it up: It's a very bad situation for ListViews at the moment.
（弱替代：。当然，你可以建立一个假列表视图，看起来像一个名单，但它是一个静态布局出了支持的意见，但不会滚动）
(Weak alternative: Of course you can build a "fake listview" that looks like a list, but is a static layout out of the supported Views. But that won't scroll.)
注：我知道这是不是如何真正做到这一点更是你能的答案 - 这是实际问题。我认为它还是有用的，因为它是一个奇怪的局面。你经常看到列表视图的工作，但你不能让它运行可以迷惑人的新的平台。我希望这是明确的，当你能够使用它。
Note: I'm aware that this is more of an "can you" answer than how to actually do it - which is the actual question. I think it's still useful since it is a weird situation. You see often that ListViews work, but you can't get it to run which may confuse people new to the platform. I hope this makes clear, when you are able to use it.
