Slide Diagonal Animation.

[root-ansh]

Hi. Firstly, Thanks for this awesome library. I am new to animations, so While Trying the Slide() Animation, I thought of making a "Diagonal Animation"(Text going from centre to left-bottom) by adding parameter Gravity.LEFT|Gravity.BOTTOM as gravity, like this:

    Button bt3BotLeft=root3.findViewById(R.id.bt_3bottomleft);

        View.OnClickListener l=new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                switch (v.getId()){
                   case (...):
                        ....
                    case R.id.bt_3bottomleft:
                        TransitionManager.beginDelayedTransition(root3,new Slide(Gravity.LEFT|Gravity.BOTTOM));break;

                }
                tvText3.setVisibility(tvText3.getVisibility()==View.VISIBLE?View.INVISIBLE:View.VISIBLE);

            }
        };

        bt3BotLeft.setOnClickListener(l);

    }

But this caused Invalid slide direction Error :

I think what i did intuitively was a wrong way of doing . So is there a right method to do so using this library? What i want to achieve is a an image of size 100*200 dp in center going towards the the bottom left edge of screen while decreasing its size on clicking.

Hi. Slide transitions is not supposed to work with diagonals. You can achieve for example it with Explode transition if provide epicentre somewhere into right top corner of the container.
