Android uses SVG resource files (1) and androidsvg

I will not introduce the background here. Let's talk about how to use SVG resources in Android!
Procedure:
1. source file of the SVG Resource
To use SVG resources, we must first have svg resources. Where can we find them? There are many tools that can generate SVG resources, such as the omnigraffle graphic editor. Here I have generated an image of SVG resources.

Open it in a browser and you will see its code.

What we need is the svg code after path, which is copied to our code.

By now, our svg resources are ready, and the next step is to use them in the code.

2. Compile the vector drawable resource file.

<?xml version="1.0" encoding="utf-8"?><vector xmlns:android="http://schemas.android.com/apk/res/android"    android:width="600dp"    android:height="600dp"    android:viewportHeight="512"    android:viewportWidth="512">    <path android:fillColor="#410a0a0a"        android:pathData="@string/pretty_girl"/></vector>

These attributes are explained here;
Android: width = "600dp" the actual display width is 600dp
Android: height = "600dp" the actual height displayed is 600dp.
Android: viewportHeight = "512" the width of the vector is 512, which has no unit;
Android: viewportWidth = "512" vector height: 512
In fact, the above two attributes are the width and height of the svg image.

Android: pathData = "@ string/pretty_girl", that is, the path of the image content. The value in the path generally does not exceed the value of viewportHeight and viewportWidth. In this case, it will not exceed 512.

3. Use it. Like other drawable resource files, you can directly set the View background or the src resource of ImageView.

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent">    <ImageView        android:id="@+id/id_img"        android:layout_centerInParent="true"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:src="@drawable/pretty_girl"/></RelativeLayout>

After running:

This is a success! However, this effect is only supported by Android5.0 and later versions. Therefore, it does not make much sense to study it. At present, it does not make much sense! So I was wondering, can a lower version of the system support SVG vector images? The answer is yes. Next Android uses SVG resource files (II) to explain how to use SVG files in earlier versions. If you are interested in SVG, you can continue to pay attention to them.

No code is pasted here, because it can only be run in systems above android.
