ImageView的配合不拉伸的图像 [英] ImageView fit without stretching the image

问题描述

是有可能，我的的ImageView 将适合所有屏幕尺寸，从而使图像显得捉襟见肘？

我尝试了所有类型的规模与它 FILL_PARENT > WRAP_CONTENT

但仍。如果图像是不小的，它只是看起来拉长。

例如：

 ＆LT; ImageView的
    机器人：layout_width =FILL_PARENT
    机器人：layout_height =WRAP_CONTENT
    机器人：scaleType =centerInside
    机器人：adjustViewBounds =真
    机器人：背景=@绘制/背景/＆GT;＆LT; ImageView的
    机器人：layout_width =FILL_PARENT
    机器人：layout_height =WRAP_CONTENT
    机器人：scaleType =fitXY
    机器人：adjustViewBounds =真
    机器人：背景=@绘制/背景/＆GT;
 

2，这些适合的宽度，但图像被拉伸..但是当我将其更改为src中的形象只是居中和小。

解决方案

有没有内置的规模型，使的ImageView 来自动的高档形象的和的保持它的长宽比不变。 ，做倍增唯一的规模类型是 fitXY ，这将不尊重宽高比，因为你发现你自己了。

话虽这么说，这个话题已经被参观了不止一次。看看一些类似的问题所提出的建议的：

• ImageView一个尺寸适合的自由空间和第二评估，以保持纵横比


• Fit图像插入ImageView的，保持宽高比，然后调整ImageView的图像尺寸是多少？


• Resizing的ImageView以适应宽高比

我sure'll是堆越多，所以它使用搜索框的顶部可能值得的。

is it possible that my ImageView will fit to all screen sizes without the image look stretched?

i tried all scale types changing it to background and src with fill_parent > wrap_content

but still. if the image is not smaller it just looks stretched..

example:

<ImageView
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:scaleType="centerInside"
    android:adjustViewBounds="true"
    android:background="@drawable/background" />

<ImageView
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:scaleType="fitXY"
    android:adjustViewBounds="true"
    android:background="@drawable/background" />

these 2 fits the width but the image is stretched.. but when i change it to src the image is just centered and small.

解决方案

There is no built-in scale type that allows the ImageView to automatically upscale the image and keep its aspect ratio intact. The only scale type that does upscaling is fitXY, which won't respect the aspect ratio, as you found out yourself too.

That being said, this topic has already been visited more than once. Have a look at some of the proposed suggestions for similar questions:

• ImageView one dimension to fit free space and second evaluate to keep aspect ration
• Fit image into ImageView, keep aspect ratio and then resize ImageView to image dimensions?
• Resizing ImageView to fit to aspect ratio

I'm sure'll be heaps more, so it might worth using the search box at the top.
