以相机意图显示图库

Question

I'm working on a feature where the user can take a picture and choose from the gallery. This is basically where it starts and goes on to save the images in db.

 private void showPictureDialog(){
        AlertDialog.Builder pictureDialog = new AlertDialog.Builder(this);
        pictureDialog.setTitle("Select Action");
        String[] pictureDialogItems = {
                "Select photo from gallery",
                "Capture photo from camera" };
        pictureDialog.setItems(pictureDialogItems,
                new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        switch (which) {
                            case 0:
                                choosePhotoFromGallary();
                                break;
                            case 1:
                                takePhotoFromCamera();
                                break;
                        }
                    }
                });
        pictureDialog.show();
    }

However, I want to make the user experience better. I want to skip the dialog where the user selects one of the options (from gallery or camera) and instead show the gallery in camera intent. Something similar to this:

I hope you get my point. Thanks :)

Answer 1

1. Get all image

 public List<File> getAllShownImagesPath(Context context) { //get all images String[] columns = {MediaStore.Images.Media.DATA, MediaStore.Images.Media.DATE_ADDED, MediaStore.Images.Media.SIZE}; List<File> result = new ArrayList<>(); File f = null; final Cursor cursor = context.getContentResolver(). query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, // Specify the provider columns, // The columns we're interested in null, // A WHERE-filter query null, // The arguments for the filter-query MediaStore.Images.Media.DATE_ADDED + " DESC" ); if (cursor != null) { cursor.moveToFirst(); for (int r = 0; r < cursor.getCount(); r++, cursor.moveToNext()) { int i = cursor.getInt(cursor.getColumnIndexOrThrow(MediaStore.Images.Media.SIZE)); //int l = cursor.getString(1).length(); final int image_path_col = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA); if (i > 0) { f = new File(cursor.getString(image_path_col)); if (f.length() > 0) { result.add(f); } } } cursor.close(); } return result; } 

2. Add all image into recyclerview or listview
