英文:
How can I merge pictures Android?
问题
我有2张图片，一张是背景，另一张是完整的图片。
我想要将它们合成一张图片，就像一张在另一张上面，然后将它们保存在您的手机上作为一张图片。
我应该学习和研究哪个JAVA库？
如果您能指导我使用在Android Studio开发的同一库，我将不胜感激。
英文:
I have 2 pictures, one is a background and the other is a complete picture.
I want to create one image from both of them as if one is above the other and save them on your cell phone as one image
Which JAVA library should I study and research?
I would be happy if you would refer me to the same library I develop in Android Studio.

是的，你可以这样做：
文件夹 drawable -> 新建 -> drawable 资源文件 -> 选择文件名并点击确定
然后你会得到以下内容：
<?xml version="1.0" encoding="utf-8"?>
<selector
xmlns:tools="http://schemas.android.com/tools"
xmlns:android="http://schemas.android.com/apk/res/android">
</selector>
在 selector 标签内部，放置 layer-list 标签（记得闭合标签），在 layer-list 标签内部，放置 item 标签。
例如，你的结果可以是这样的：
<?xml version="1.0" encoding="utf-8"?>
<selector
xmlns:tools="http://schemas.android.com/tools"
xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<layer-list>
<item>
</item>
<item>
</item>
</layer-list>
</item>
</selector>
现在你可以自定义这两个项目。如果你想要在项目中放置图像，你可以像这样编写代码：
<item
android:gravity="center_vertical|center_horizontal"
android:drawable="@drawable/YOUR_IMAGE"
android:width="96dp"
android:height="96dp"
tools:ignore="UnusedAttribute" />
如果你想要放置一个对象的形状，比如一个矩形，你可以像这样编写代码：
<item>
<shape
android:shape="rectangle">
<solid
android:color="#000000" />
<size
android:width="1080px"
android:height="1920px" />
<padding
android:left="0dp"
android:top="0dp"
android:right="0dp"
android:bottom="0dp" />
</shape>
</item>
现在你的图像由两个图像（或其他内容）组成，如果你想要使用它，你只需要在你的 layout_activity.xml 文件中调用 android:background="@drawable/YOUR_FILE_NAME"。
有了这些信息，我认为你可以解决你的问题，再见 
英文:
Yes you can, this is what you have to do:
Folder drawable -> new -> drawable resource file -> choose the name of the file and click ok
and this is what you get
<?xml version="1.0" encoding="utf-8"?>
<selector
xmlns:tools="http://schemas.android.com/tools"
xmlns:android="http://schemas.android.com/apk/res/android">
</selector>
Inside the tags selector put the tag <layer-list> (remember to close the tag) and inside the layer-list put the tag <item>
your result can be this for example:
<?xml version="1.0" encoding="utf-8"?>
<selector
xmlns:tools="http://schemas.android.com/tools"
xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<layer-list>
<item>
</item>
<item>
</item>
</layer-list>
</item>
</selector>
Now you can customize your 2 items, if you want to put an image inside your item you can write your code like this:
<item
android:gravity="center_vertical|center_horizontal"
android:drawable="@drawable/YOUR_IMAGE"
android:width="96dp"
android:height="96dp"
tools:ignore="UnusedAttribute" />
if you want to put a shape of an object like a rectangle you can write your code like this:
<item>
<shape
android:shape="rectangle">
<solid
android:color="#000000" />
<size
android:width="1080px"
android:height="1920px" />
<padding
android:left="0dp"
android:top="0dp"
android:right="0dp"
android:bottom="0dp" />
</shape>
</item>
Now you have your image composed with 2 images (or other things) and if you want to use it you can just call android:background="@drawable/YOUR_FILE_NAME" inside your layout_activity.xml for example
with this informations I think you can solve your problem, cya
