Android imagebutton how to change icon size
提问by Loic O.
I have been working on interfaces lately and I have many problems with imagebutton sizes. I'm very bad at designing stuff and I'm having major problems with the Android Icons. Thus, I have some questions regarding those.
我最近一直在研究界面，我在图像按钮大小方面遇到了很多问题。我在设计东西方面非常糟糕，而且我在 Android 图标方面遇到了重大问题。因此，我对这些有一些疑问。
First of all this is my current layout:
首先这是我目前的布局：
As you can see, I have two icons that have different sizes and that's not good. I can't seem to force them to take the same size.
如您所见，我有两个大小不同的图标，这并不好。我似乎无法强迫它们采用相同的尺寸。
My questions are:
我的问题是：
1 - How do I force them to take the same size?
1 - 我如何强制它们采用相同的尺寸？
2 - What are the recommended size differences for hdpi, ldpi,mdpi and xhdpi?
2 - hdpi、ldpi、mdpi 和 xhdpi 的推荐大小差异是多少？
3 - Why, if I set the imageButton background color to the same color as the layout background, the Icon is moved as if there was no button in the background?
3 - 为什么，如果我将 imageButton 背景颜色设置为与布局背景相同的颜色，图标会像背景中没有按钮一样移动？

For these ImageButtons set the images using (instead of src):
对于这些 ImageButtons 使用（而不是 src）设置图像：
android:background="@drawable/image_name"
Next thing is set:
接下来设置：
android:layout_height="10dp" //or any size required
android:layout_width="10dp" //or any size required ... let these 2 sizes be same for both the ImageButtons
"dp" or "dip" is device independent pixels. The android system will take care of the resizing for different screen resolutions
“dp”或“dip”是与设备无关的像素。android 系统将负责调整不同屏幕分辨率的大小
Also, a better thing to do would be to set-up hover images for your button separately.
此外，更好的做法是分别为您的按钮设置悬停图像。

android:layout_height="10dp"
android:layout_width="10dp"
Dont keep in px, always you have to keep in only dp
不要保持px，总是你只需要保持dp
回答by ScouseChris
As the other answers have said, set the button sizes using dp or dip in the layout xml files.
正如其他答案所说，在布局 xml 文件中使用 dp 或 dip 设置按钮大小。
