Java使用camerax的例子

在github，自己看吧
https://github.com/7eau/CameraXDemo_Java

camerax版本

def camerax_version = "1.1.0-beta01"
implementation "androidx.camera:camera-core:${camerax_version}"
implementation "androidx.camera:camera-camera2:${camerax_version}"
implementation "androidx.camera:camera-lifecycle:${camerax_version}"
implementation "androidx.camera:camera-video:${camerax_version}"

implementation "androidx.camera:camera-view:${camerax_version}"
implementation "androidx.camera:camera-extensions:${camerax_version}"

如果出现相机拍照的分辨率不对需要设置preview的分辨率
