    I think I encountered your case before. An idea is that we will create a one item list alert dialog with selectable item, and each item will do a unique function defined by your own intention. If you want an icon for each element in items list, it should take a bit more work to do. Hope it will helpful.

        String title = "Open Photo";
        CharSequence[] itemlist ={"Take a Photo",
                      "Pick from Gallery",
                      "Open from File"};
    
        AlertDialog.Builder builder = new AlertDialog.Builder(this);
        builder.setIcon(R.drawable.icon_app);
        builder.setTitle(title);
        builder.setItems(itemlist, new DialogInterface.OnClickListener() {
    
            @Override
            public void onClick(DialogInterface dialog, int which) {
                switch (which) {
                case 0:// Take Photo
                    // Do Take Photo task here
                    break;
                case 1:// Choose Existing Photo
                    // Do Pick Photo task here
                    break;
                case 2:// Choose Existing File
                    // Do Pick file here
                    break;
                default:
                    break;
                }
            }
        });
        AlertDialog alert = builder.create();
        alert.setCancelable(true);
        alert.show();

    If you want to take picture from Camera or Gallery Intent Together, Then check below link. Same question also posted here.

    Capturing image from gallery & camera in android

    UPDATED CODE:

    check below code, In this code not same as you want into listview, but it gives the option in the dialogBox choose image from Gallary OR Camera.

    public class UploadImageActivity extends Activity {
    ImageView img_logo;
    protected static final int CAMERA_REQUEST = 0;
    protected static final int GALLERY_PICTURE = 1;
    private Intent pictureActionIntent = null;
    Bitmap bitmap;
    
        String selectedImagePath;
    
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main1);
    
        img_logo= (ImageView) findViewById(R.id.imageView1);
        img_logo.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {
                startDialog();
            }
    
        });
    }
    
    private void startDialog() {
        AlertDialog.Builder myAlertDialog = new AlertDialog.Builder(
                getActivity());
        myAlertDialog.setTitle("Upload Pictures Option");
        myAlertDialog.setMessage("How do you want to set your picture?");
    
        myAlertDialog.setPositiveButton("Gallery",
                new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface arg0, int arg1) {
                        Intent pictureActionIntent = null;
    
                        pictureActionIntent = new Intent(
                                Intent.ACTION_PICK,
                                android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
                         startActivityForResult(
                                pictureActionIntent,
                                GALLERY_PICTURE);

    Also add pemission:

    store Image to sdcard:

    private void storeImageTosdCard(Bitmap processedBitmap) {
        try {
            // TODO Auto-generated method stub
    
            OutputStream output;
            // Find the SD Card path
            File filepath = Environment.getExternalStorageDirectory();
            // Create a new folder in SD Card
            File dir = new File(filepath.getAbsolutePath() + "/appName/");
            dir.mkdirs();
    
            String imge_name = "appName" + System.currentTimeMillis()
                    + ".jpg";
            // Create a name for the saved image
            File file = new File(dir, imge_name);
            if (file.exists()) {
                file.delete();
                file.createNewFile();
            } else {
                file.createNewFile();
    
            }
    
            try {
    
                output = new FileOutputStream(file);
    
                // Compress into png format image from 0% - 100%
                processedBitmap
                        .compress(Bitmap.CompressFormat.PNG, 100, output);
                output.flush();
                output.close();
    
                int file_size = Integer
                        .parseInt(String.valueOf(file.length() / 1024));
                System.out.println("size ===>>> " + file_size);
                System.out.println("file.length() ===>>> " + file.length());
    
                selectedImagePath = file.getAbsolutePath();
    
    
    
            }
    
            catch (Exception e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();

    Let's say that you have two intents. One that would open a camera, one that would open a gallery. I will call these cameraIntent and gallerIntent in the example code. You can use intent chooser to combine these two:

    Kotlin:

    val chooser = Intent.createChooser(galleryIntent, "Some text here")
    chooser.putExtra(Intent.EXTRA_INITIAL_INTENTS, arrayOf(cameraIntent))
    startActivityForResult(chooser, requestCode)
    

    Java:

    Intent chooser = Intent.createChooser(galleryIntent, "Some text here");
    chooser.putExtra(Intent.EXTRA_INITIAL_INTENTS, new Intent[] { cameraIntent });
    startActivityForResult(chooser, requestCode);
    

    This is, as you asked, how you can put the two together (without having to make your own UI/ dialog).

    If you want to show all the apps installed in the phone that can deal with photos such as Camera, Gallery, Dropbox, etc.

    You can do something like:

    1.- Ask for all the intents available:

        Intent camIntent = new Intent("android.media.action.IMAGE_CAPTURE");
        Intent gallIntent=new Intent(Intent.ACTION_GET_CONTENT);
        gallIntent.setType("image/*"); 
    
        // look for available intents
        List<ResolveInfo> info=new ArrayList<ResolveInfo>();
        List<Intent> yourIntentsList = new ArrayList<Intent>();
        PackageManager packageManager = context.getPackageManager();
        List<ResolveInfo> listCam = packageManager.queryIntentActivities(camIntent, 0);
        for (ResolveInfo res : listCam) {
            final Intent finalIntent = new Intent(camIntent);
            finalIntent.setComponent(new ComponentName(res.activityInfo.packageName, res.activityInfo.name));
            yourIntentsList.add(finalIntent);
            info.add(res);
        }
        List<ResolveInfo> listGall = packageManager.queryIntentActivities(gallIntent, 0);
        for (ResolveInfo res : listGall) {
            final Intent finalIntent = new Intent(gallIntent);
            finalIntent.setComponent(new ComponentName(res.activityInfo.packageName, res.activityInfo.name));
            yourIntentsList.add(finalIntent);
            info.add(res);
        }
    

    2.- Show a custom dialog with the list of items:

        AlertDialog.Builder dialog = new AlertDialog.Builder(context);
        dialog.setTitle(context.getResources().getString(R.string.select_an_action));
        dialog.setAdapter(buildAdapter(context, activitiesInfo),
                new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int id) {
                        Intent intent = intents.get(id);
                        context.startActivityForResult(intent,1);
                    }
                });
    
        dialog.setNeutralButton(context.getResources().getString(R.string.cancel),
                new android.content.DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        dialog.dismiss();
                    }
                });
        dialog.show();
    

    This is a full example: https://gist.github.com/felixgborrego/7943560

    Create a button in your XML layout and the add the attribute android:onClick="takeAPicture" then in your main activity create a method with the same name from the onClick attribute.

    public void takeAPicture(View view){
        Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
            intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
            intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1);
            startActivityForResult(intent, IMAGE_CAPTURE);
    }
    

    And just do another method for when you want to get the image from the gallery:

    public void getImageFromGallery(View view) {
        Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
            intent.setType("image/*");
            intent.setAction(Intent.ACTION_GET_CONTENT);
            startActivityForResult(Intent.createChooser(intent,
                        "Select Picture"), SELECT_PICTURE);
    }
