Question

我正在尝试基于CameraX构建相机应用程序，并希望为相机预览启用散景（模糊）效果。这可以通过CameraX扩展来完成，但是如何启用它们？

我已经在Android Developer Docs阅读了有关供应商扩展的文章。我试图重用他们的方法，但是CameraX var request = await client.FetchAccountInfoAsync(new Acklann.Plaid.Auth.GetAccountInfoRequest() { AccessToken = accessToken.AccessToken, ClientId = "<clientid>", Secret = "<secret>", Options = new Acklann.Plaid.Auth.GetAccountInfoOptions { AccountIds = bankId } });

中未包含示例中显示的类

alpha-02

我希望import androidx.camera.extensions.BokehExtender; void onCreate() { // Create a Builder same as in normal workflow. ImageCaptureConfig.Builder builder = new ImageCaptureConfig.Builder(); // Create a Extender object which can be used to apply extension // configurations. BokehImageCaptureExtender bokehImageCapture = new BokehImageCaptureExtender(builder); // Query if extension is available (optional). if (bokehImageCapture.isExtensionAvailable()) { // Enable the extension if available. bokehImageCapture.enableExtension(); } // Finish constructing configuration with the same flow as when not using // extensions. ImageCaptureConfig config = builder.build(); ImageCapture useCase = new ImageCapture(config); CameraX.bindToLifecycle((LifecycleOwner)this, useCase); }将被导入，但看起来好像仍未提供。整个包BokehImageCaptureExtender都丢失了。

此类可以在官方AndroidX git repository上找到，但是如果不导入完整的AndroidX项目，则很难进行设置。

我刚刚注意到编辑问题，并here选择显示为 Java 的代码示例，但您放了 Kotlin 作为标识符。确保您使用正确的语言。这可能是问题所在。

这是来自Android Developer Docs的 Kotlin 示例：

import androidx.camera.extensions.BokehExtender

fun onCreate() {
    // Create a Builder same as in normal workflow.
    val builder = ImageCaptureConfig.Builder()

    // Create a Extender object which can be used to apply extension
    // configurations.
    val bokehImageCapture = BokehImageCaptureExtender.create(builder)

    // Query if extension is available (optional).
    if (bokehImageCapture.isExtensionAvailable()) {
        // Enable the extension if available.
        bokehImageCapture.enableExtension()
    }

    // Finish constructing configuration with the same flow as when not using
    // extensions.
    val config = builder.build()
    val useCase = ImageCapture(config)
    CameraX.bindToLifecycle(this as LifecycleOwner, useCase)
}

这是来自Android Developer Docs的 Java 示例：

import androidx.camera.extensions.BokehExtender;

void onCreate() {
    // Create a Builder same as in normal workflow.
    ImageCaptureConfig.Builder builder = new ImageCaptureConfig.Builder();

    // Create a Extender object which can be used to apply extension
    // configurations.
    BokehImageCaptureExtender bokehImageCapture = new
            BokehImageCaptureExtender(builder);

    // Query if extension is available (optional).
    if (bokehImageCapture.isExtensionAvailable()) {
        // Enable the extension if available.
        bokehImageCapture.enableExtension();
    }

    // Finish constructing configuration with the same flow as when not using
    // extensions.
    ImageCaptureConfig config = builder.build();
    ImageCapture useCase = new ImageCapture(config);
    CameraX.bindToLifecycle((LifecycleOwner)this, useCase);
}

扩展名在Google Maven上仍然不可用 https://dl.google.com/dl/android/maven2/index.html

Android CameraX扩展仅存在于以下版本中：“ 1.0.0-alpha01” 。

降级您的相机版本： //相机Jetpack库

def camerax_version = "1.0.0-alpha01"
implementation "androidx.camera:camera-core:$camerax_version"
implementation "androidx.camera:camera-camera2:$camerax_version"
implementation "androidx.camera:camera-extensions:$camerax_version"

如何启用Android CameraX供应商扩展？
