在Android的选项菜单舒展本地图标填写菜单项，晦涩题名 [英] Local icons in Android Options Menu stretch to fill menu item, obscure Title

问题描述

我是新的，所以链接和图像这里 的

我可能会做出愚蠢的错误...希望能找出是什么。

I'm likely making a silly mistake... hoping to find out what that is.

我想在我的应用程序的选项菜单使用一些标准的菜单图标（ic_menu_refresh等）。我想设置的图标在菜单中的XML文件。我说我可以用下面的几个地方读：

I'd like to use a few of the standard menu icons (ic_menu_refresh, etc.) in my app's Options Menu. And I'd like to set the icons in the xml file for the menu. I read in a few places that I can use the following:

<item android:id="@+id/quit"
      android:icon="@android:drawable/ic_menu_close_clear_cancel"
      android:title="Quit" />

要在我的菜单中退出按钮。这很好地工作。不过，我也想使用一些其他的图标，如ic_menu_stop.png，这显然是不公开的 [链接1] 。另外，我读过在一些地方，这不是一个好主意引用内部图形像 [链接2] 。同样，我不想用星号替代方法的 [LINK3] 以允许访问私有资源。所提供的解决方案是使可绘的本地副本。

to make a quit button in my menu. And this works nicely. However, I'd also like to use some other icons, like ic_menu_stop.png, which are apparently "not public" [link1]. Also, I've read in a few places that it's not a great idea to "reference internal graphics like that" [link2]. Likewise, I don't want to use the asterisk workaround [link3] to allow access to private resources. The solution offered is to make a local copy of the drawables.

所以我复制的图像文件，我从Ç想：\\ ... \\ Android的8 \\ DATA \\水库\\绘制，华电国际到我的项目的水库\\绘制文件夹，然后改变了上述的XML：

So I copied the image files I wanted from C:\...\android-8\data\res\drawable-hdpi into my project's res\drawable folder, and then changed the above xml to:

<item android:id="@+id/quit"
      android:icon="@drawable/ic_menu_close_clear_cancel"
      android:title="Quit" />

然而，这将导致图标伸展（我相信图标被拉伸 - 而不是简单的一个更大的（华电国际）图像文件 - 因为它是有点模糊），要么晦涩或排挤标题文本，所以我看到的是过大的，模糊的图标。当然，我也尝试复制从图标绘，MDPI 文件夹：使用于mdpi图标不会遮挡的称号，但图标是slighlty矮小和模糊。

However, this causes the icon to stretch (I believe the icon is stretched - and not simply a bigger (hdpi) image file - because it's slightly blurred) and either obscure or crowd out the title text, so all I see is the oversized, blurry icon. Of course, I also tried copying the icon from the drawable-mdpi folder: using the mdpi icon doesn't obscure the title, but the icon is slighlty undersized and blurry.

我想一个截图，所以我切换到我的模拟器中运行的应用程序。然而，模糊不明显，和当地MDPI形象似乎符合内部的那个我引用：

I wanted a screenshot, so I switched to running the app on my emulator. However, the blurring isn't apparent, and the local mdpi image seems to match the internal one I'm referencing:

[画面] （适用于跟随顶部的链接！）

[screenshot] (follow the link at the top!)

我有双重检查:)，它真的是模糊我的手机（摩托罗拉Droid）。在

I have double-checked :), and it really is blurred on my phone (Motorola Droid).

这也发生在我所引用的人们可能会得到通过一个XML文件（如国家列表绘制）的图标，XML文件以某种方式定义的图像是如何被绘制。我试图使一个具有位图元素，并尝试设置几个属性的方面，我想可能有帮助：

It also occurred to me that the referenced one might be getting the icon via an xml file (like a state-list drawable), and that the xml file somehow defined how the image was to be drawn. I tried making one with a bitmap element, and tried setting a couple of the properties in ways I thought might help:

<?xml version="1.0" encoding="utf-8"?>
<bitmap xmlns:android="http://schemas.android.com/apk/res/android" 
 android:src="@drawable/ic_menu_close_clear_cancel"
 android:gravity="top"
 android:filter="false" />

它的工作要显示的图标（我为自己感到骄傲），但并没有影响拉伸的问题。

It worked to display the icon (I was proud of myself), but didn't affect the stretching issue.

我还发现这些的 [LINK4和link5] 页，但他们似乎有不同的问题。

I also found these [link4 and link5] pages, but they seemed to have different issues.

也许我应该抄袭其他位置的图标？我在正确的轨道与xml文件吗？帮助？

Perhaps I should be copying the icons from another location? Am I on the right track with the xml file? Help?

谢谢，

推荐答案

如果你想拥有的图标在所有屏幕密度正常显示，那么你应该创建自己的绘制，MDPI，绘制，华电国际等文件夹和复制图标到每个那些。

If you want to have the icon appear correctly in all screen densities, then you should create your own drawable-mdpi, drawable-hdpi, etc folders and copy the icons into each of those.

这种方式正确大小的图标将被用于每个密度。有关如何工作的更多详细信息，请参阅支持多种屏幕尺寸，特别是部分资源预选赛。

That way the correct size icon will be used for each density. For more details on how this works, see supporting multiple screen sizes, particularly the section on resource qualifiers.
