2024-11-22 15:57:02 分类：技术问答 阅读(133) 评论(0)

要使用Android CameraX库初始化相机，请按照以下步骤操作：

  1. 首先，确保在项目的build.gradle文件中添加了CameraX库的依赖项：
dependencies {
    implementation 'androidx.camera:camera-core:1.0.0'
    implementation 'androidx.camera:camera-camera2:1.0.0'
    implementation 'androidx.camera:camera-view:1.0.0'
}
  1. 在AndroidManifest.xml文件中添加必要的权限：
  1. 在activity_main.xml布局文件中添加CameraView组件：
  1. 在MainActivity.java文件中初始化CameraX：
