CameraX需要java8环境

android {
    ...
    compileOptions {
        sourceCompatibility = 1.8
        targetCompatibility = 1.8
    }
}
	

    <uses-feature android:name="android.hardware.camera" />
    <uses-feature android:name="android.hardware.camera.autofocus" />
    <uses-feature android:name="android.hardware.location.gps" />

    <uses-permission android:name="android.permission.CAMERA" />
    <uses-permission android:name="android.permission.FLASHLIGHT" />
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.RECORD_AUDIO" />
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

 
基于Camera2 Api的Custom版本，拍照速度更快
<com.hbzhou.open.flowcamera.CustomCameraView
        android:id="@+id/customCamera"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        />
基于CameraX库flow版本,兼容性稳定性进一步增强
<com.hbzhou.open.flowcamera.FlowCameraView
        android:id="@+id/flowCamera"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        />

在fragment或者activity调用 Android6.0以上系统需要自行动态申请 存储 相机和麦克风权限

使用CustomCameraView按照如下步骤配置 

val flowCamera = findViewById<CustomCameraView>(R.id.flowCamera)
	// 绑定生命周期 您就不用关心Camera的开启和关闭了 不绑定无法预览
        flowCamera.setBindToLifecycle(this)
        // 设置白平衡模式
        flowCamera.setWhiteBalance(WhiteBalance.AUTO)
	// 设置只支持单独拍照拍视频还是都支持
        // BUTTON_STATE_ONLY_CAPTURE  BUTTON_STATE_ONLY_RECORDER  BUTTON_STATE_BOTH
        flowCamera.setCaptureMode(BUTTON_STATE_BOTH)
        // 开启HDR
        flowCamera.setHdrEnable(Hdr.ON)
        // 设置最大可拍摄小视频时长
        flowCamera.setRecordVideoMaxTime(10)
        // 设置拍照或拍视频回调监听
        flowCamera.setFlowCameraListener(object : FlowCameraListener {
            // 录制完成视频文件返回
            override fun recordSuccess(file: File) {
                ToastUtils.showLong(file.absolutePath)
                finish()
            }
            // 操作拍照或录视频出错
            override fun onError(videoCaptureError: Int, message: String, cause: Throwable?) {

            }
            // 拍照返回
            override fun captureSuccess(file: File) {
                ToastUtils.showLong(file.absolutePath)
                finish()
            }
        })
        //左边按钮点击事件
        flowCamera.setLeftClickListener {
            finish()
        }
