中心绘制和规模高度 [英] Center drawable and scale height

问题描述

由于我要支持平板电脑和智能手机而不释放一个特殊的HD版，我需要根据用户设备的分辨率缩放我的图片。这是一个看起来对三星Galaxy Nexus的好ImageView的来源：

Since I want to support tablets and smartphones without delivering a special "HD" version, I need to scale my Images depending on the resolution of the users device. This is the ImageView source that looks good on the Samsung Galaxy Nexus:

  <ImageView
                        android:id="@+id/character"
                        android:layout_width="wrap_content" 
                        android:layout_height="wrap_content"
                        android:layout_alignParentBottom="true"
                        android:layout_centerHorizontal="true"
                        android:background="@android:color/transparent"
                      android:scaleType="centerCrop"
                       android:src="@drawable/ma_un1_001" />

但是，将削减对的Nexus 7的图像。

But it will cut the image on the nexus 7.

当我改变的宽度和高度为：

When I changed the width and height to:

<ImageView
                android:id="@+id/character"
                android:layout_width="fill_parent"
                android:layout_height="fill_parent"
                android:layout_alignParentBottom="true"
                android:background="@android:color/transparent"
                android:scaleType="centerCrop"
                android:src="@drawable/ma_un1_001" />

不幸的是这将缩放图像出来的观点：

Unfortunately this scales the image out of the view:

修改XML以

android:layout_width="wrap_content"
android:layout_height="fill_parent"

仍然会削减图像。

Would still cut the image.

于是我改变了scaleType到FIT_START

So I changed the scaleType to FIT_START

<ImageView
                android:id="@+id/character"
                android:layout_width="fill_parent"
                android:layout_height="fill_parent"
                android:layout_alignParentBottom="true"
                android:background="@android:color/transparent"
                android:scaleType="fitStart"
                android:src="@drawable/ma_un1_001" />

看起来对我的所有设备都很大，​​但绘制的左对齐。
有什么办法来居中？

Looks great on all my devices, but the drawable is aligned to the left. Is there any way to center it?

推荐答案

感谢文辉我找到了解决办法。

Thanks to Wenhui I found the solution.

 <ImageView
                android:id="@+id/character"
                **android:layout_width="fill_parent"
                android:layout_height="fill_parent"**
                android:layout_alignParentBottom="true"
                android:background="@android:color/transparent"
                **android:scaleType="fitCenter"**
                android:src="@drawable/ma_un1_001" />

缩放图像的每一个屏幕尺寸，并不会削减任何东西。非常感谢你。

Scales the Image to every screensize and won't cut anything. Thank you very much.
