【Android】RuntimeShader 应用

1 简介

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity"
android:orientation="vertical"
android:gravity="center"
android:background="#FFFFFF"
android:id="@+id/parent">

<TextView
   android:layout_width="wrap_content"
   android:layout_height="wrap_content"
   android:text="Hello World"
   android:textSize="60sp"
   android:textColor="#669933"/>

</LinearLayout>RuntimeShader 是 Android 13（T）中新增的特性，用于逐像素渲染界面，它使用 AGSL（Android Graphics Shading Language）编写着色器代码，底层基于 Skia 图形渲染引擎。官方介绍详见 → RuntimeShader。
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity"
android:orientation="vertical"
android:gravity="center"
android:background="#FFFFFF"
android:id="@+id/parent">

<TextView
   android:layout_width="wrap_content"
   android:layout_height="wrap_content"
   android:text="Hello World"
   android:textSize="60sp"
   android:textColor="#669933"/>

</LinearLayout>相较于 OpenGL ES，RuntimeShader 具有以下特点。

[*]RuntimeShader 中只有片元着色器，没有顶点着色器。
[*]RuntimeShader 中用户不用输入顶点数据，简化了输入操作。
[*]RuntimeShader 基于 AGSL 语言，OpenGL ES 基于 GLSL 语言。
[*]AGSL 中纹理坐标值域与 View 的宽高对应，GLSL 中纹理坐标一般归一化了。
