在Android 11中，相机意向（Camera Intents）不再像之前那样直接响应。为了适应此更改，您可以使用新的相机X包或使用相机API来解决这个问题。以下是一些解决方法的示例代码：

1. 使用相机X包

首先，请确保在您的项目中添加了相机X包的依赖项。在build.gradle文件中添加以下依赖项：

dependencies {
    implementation 'androidx.camera:camera-camera2:1.1.0-alpha09'
    implementation 'androidx.camera:camera-lifecycle:1.1.0-alpha09'
    implementation 'androidx.camera:camera-view:1.0.0-alpha23'
}

然后，在您的Activity或Fragment中，您可以使用相机X库来处理相机意向。以下是一个示例代码：

import androidx.appcompat.app.AppCompatActivity;
import androidx.camera.lifecycle.ProcessCameraProvider;
import androidx.camera.view.PreviewView;
import androidx.camera.core.CameraSelector;
import androidx.camera.core.ImageCapture;
import androidx.camera.core.ImageCaptureException;

import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
import android.widget.Toast;

import com.google.common.util.concurrent.ListenableFuture;

import java.util.concurrent.ExecutionException;

public class MainActivity extends AppCompatActivity {

    private ListenableFuture cameraProviderFuture;
    private PreviewView previewView;
    private ImageCapture imageCapture;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // Initialize the preview view
        previewView = findViewById(R.id.cameraPreview);

        // Initialize the camera provider
        cameraProviderFuture = ProcessCameraProvider.getInstance(this);

        // Request camera permissions if needed
        // ...

        // Set up the camera provider
        cameraProviderFuture.addListener(() -> {
            try {
                ProcessCameraProvider cameraProvider = cameraProviderFuture.get();
                bindCameraUseCases(cameraProvider);
            } catch (ExecutionException | InterruptedException e) {
                e.printStackTrace();
            }
        }, ContextCompat.getMainExecutor(this));
    }

    private void bindCameraUseCases(ProcessCameraProvider cameraProvider) {
        // Set up the preview use case
        Preview preview = new Preview.Builder().build();
        preview.setSurfaceProvider(previewView.getSurfaceProvider());

        // Set up the image capture use case
        imageCapture = new ImageCapture.Builder().build();

        // Set up the camera selector
        CameraSelector cameraSelector = new CameraSelector.Builder()
                .requireLensFacing(CameraSelector.LENS_FACING_BACK)
                .build();

        // Bind the use cases to the camera provider
        cameraProvider.bindToLifecycle(this, cameraSelector, preview, imageCapture);
    }

    // Handle the result of the camera intent
    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
            // Handle the captured image
            // ...
        }
    }

    // Capture an image
    private void captureImage() {
        File photoFile = createPhotoFile();
        ImageCapture.OutputFileOptions outputFileOptions =
                new ImageCapture.OutputFileOptions.Builder(photoFile).build();

        imageCapture.takePicture(outputFileOptions, ContextCompat.getMainExecutor(this),
                new ImageCapture.OnImageSavedCallback() {
                    @Override
                    public void onImageSaved(ImageCapture.OutputFileResults outputFileResults) {
                        // Image capture success
                        // ...
                    }

                    @Override
                    public void onError(ImageCaptureException exception) {
                        // Image capture error
                        // ...
                    }
                });
    }

    // Create a file to save the captured image
    private File createPhotoFile() {
        // ...
    }
}

2. 使用相机API

如果您不想使用相机X包，您仍然可以使用相机API来处理相机意向。以下是一个示例代码：

import android.content.Intent;
import android.graphics.Bitmap;
import android.provider.MediaStore;
import android.os.Bundle;
import android.widget.ImageView;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity {

    private static final int REQUEST_IMAGE_CAPTURE = 1;
    private ImageView imageView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // Initialize the image view
        imageView = findViewById(R.id.imageView);

        // Launch the camera intent
        Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
            startActivityForResult(takePictureIntent
