Android：列出所有图库应用程序和相机以从中选择图片

Question

我正在尝试从相机或图库中选择图像并使用以下代码，并希望所有图库选项都可以在第一个选择器屏幕中使用，而不是在另一个选项下合并。

open fun getImageFromPhone() {
        val pickIntent = Intent()
        pickIntent.type = "image/*"
        pickIntent.action = Intent.ACTION_GET_CONTENT
        val takePhotoIntent = Intent(MediaStore.ACTION_IMAGE_CAPTURE)
        val galleryIntent = Intent(
            Intent.ACTION_PICK,
            android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI
        )
        galleryIntent.setType("image/gallery");
        val pickTitle = "Select or take a new Picture"
        var outputFileUri: Uri? = Uri.fromFile(File.createTempFile(TEMP_FILE, EXTENSION))
        val chooserIntent = Intent.createChooser(pickIntent, pickTitle)
        chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, arrayOf(takePhotoIntent, galleryIntent))
        chooserIntent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri)
        startActivityForResult(chooserIntent, CODE_IMG_GALLERY)
    }

这会导致显示以下选项：

点击Android System 我得到画廊选项：

但是，我希望这些选项（在上图中）在第一个菜单本身中作为单独的选项列出。

此方法用于从相机的(ACTION_IMAGE_CAPTURE) 或图库(ACTION_GET_CONTENT) 中选择图像源。我已经发布了所有相关的方法，效果很好。只需按如下方式调用此 Intent：

startActivityForResult(getPickImageChooserIntent(activity,"Your Title",false),PICK_IMAGE_CHOOSER_REQUEST_CODE)

   

    public static Intent getPickImageChooserIntent(@NonNull Context context, CharSequence 
    title, boolean includeDocuments) {
    List<Intent> allIntents = new ArrayList<>();
    PackageManager packageManager = context.getPackageManager();

    // collect all camera intents if Camera permission is available
    if (!isExplicitCameraPermissionRequired(context)) {
      allIntents.addAll(getCameraIntents(context, packageManager));
    }
    List<Intent> galleryIntents =
            getGalleryIntents(packageManager, Intent.ACTION_GET_CONTENT,includeDocuments);
    if (galleryIntents.size() == 0) {
      // if no intents found for get-content try pick intent action (Huawei P9).
      galleryIntents = getGalleryIntents(packageManager, Intent.ACTION_PICK, includeDocuments);
    }
    allIntents.addAll(galleryIntents);

    Intent target;
    if (allIntents.isEmpty()) {
      target = new Intent();
    } else {
      target = allIntents.get(allIntents.size() - 1);
      allIntents.remove(allIntents.size() - 1);
    }

    // Create a chooser from the main  intent
    Intent chooserIntent = Intent.createChooser(target, title);

    // Add all other intents
    chooserIntent.putExtra(
            Intent.EXTRA_INITIAL_INTENTS, allIntents.toArray(new Parcelable[allIntents.size()]));

    return chooserIntent;
    }

    public static boolean isExplicitCameraPermissionRequired(@NonNull Context context) {
    return Build.VERSION.SDK_INT >= Build.VERSION_CODES.M
        && hasPermissionInManifest(context, "android.permission.CAMERA")
        && context.checkSelfPermission(Manifest.permission.CAMERA)
            != PackageManager.PERMISSION_GRANTED;
    }

        /** Get all Camera intents for capturing image using device camera apps. */
    public static List<Intent> getCameraIntents(
            @NonNull Context context, @NonNull PackageManager packageManager) {
  
      List<Intent> allIntents = new ArrayList<>();
  
      // Determine Uri of camera image to  save.
      Uri outputFileUri = getCaptureImageOutputUri(context);
  
      Intent captureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
      List<ResolveInfo> listCam = packageManager.queryIntentActivities(captureIntent, 0);
      for (ResolveInfo res : listCam) {
        Intent intent = new Intent(captureIntent);
        intent.setComponent(new ComponentName(res.activityInfo.packageName, res.activityInfo.name));
        intent.setPackage(res.activityInfo.packageName);
        if (outputFileUri != null) {
          intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
        }
        allIntents.add(intent);
      }
  
      return allIntents;
    }
