android camerax如何初始化相机

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:
