Question

我试图在从后置摄像头改为后置摄像头后立即使用React Native相机拍摄照片。为了给您一个想法，代码看起来像这样：

state = {
    type: Camera.Constants.Type.back
}

takePicture = () => {
    const options = {quality:0.5}
    this.setState({type:Camera.Constants.Type.front}, () => {
        this.camera.takePictureAsync(options).then(data => {
            console.log(data)
        });
    })
};

我想我要拍摄的照片将是带有前置摄像头的照片。但是，我得到的照片始终是带有后置摄像头的照片。我有什么想念的吗？

在渲染方法中，您是否将类型作为属性添加？

使用本机更改相机类型后立即拍照
