如何在我的应用程序中使用camera intent时自动保存图像？

<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

private static final int REQUEST_IMAGE_CAPTURE = 1;
private Uri imageUri;

private void dispatchTakePictureIntent() {
    Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
        // 创建一个文件来保存拍摄的图像
        File photoFile = null;
        try {
            photoFile = createImageFile();
        } catch (IOException ex) {
            ex.printStackTrace();
        }
        if (photoFile != null) {
            // 将文件路径转换为URI
            imageUri = FileProvider.getUriForFile(this, "com.example.android.fileprovider", photoFile);
            // 将URI添加到相机意图中
            takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
            // 启动相机意图
            startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
        }
    }
}

private File createImageFile() throws IOException {
    // 创建一个唯一的文件名
    String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
    String imageFileName = "JPEG_" + timeStamp + "_";
    // 获取应用程序的外部存储目录
    File storageDir = getExternalFilesDir(Environment.DIRECTORY_PICTURES);
    // 创建图像文件
    File image = File.createTempFile(
        imageFileName,  /* 前缀 */
        ".jpg",         /* 后缀 */
        storageDir      /* 目录 */
    );
    return image;
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
        // 图像已成功捕获，可以在此处进行进一步的处理
        // 例如，将图像显示在ImageView中
        ImageView imageView = findViewById(R.id.imageView);
        imageView.setImageURI(imageUri);
    }
}
