Hi, I'm adding Views to the PhysicsLayout with addView(). I want to create a Joint between multiple dynamically added Views. How can I access the Body Instance right after adding the View so I can create a Joint?

I have app:fling="true" and app:physics="true" in my PhysicsFrameLayout, but I cant't fling the ImageVew inside.

Is there something extra I need to do?

Hi John, thank you for making this awesome library. I am trying to use it with my project. But when I tried to add child views to the PhysicsLinearLayout, the animation paused when new child view was added, like

physicsLayout = (ViewGroup) rootView.findViewById(R.id.physics_layout);
physicsLayout.addView(textView, params);

When a new TextView was added to the PhysicalLinearLayout meanwhile a previously added TextView was falling down, the latter will pause at the moment the new view was added. Any idea to solve this ?

Thanks again for this awesome library!

Hi,

I have encounter a performance issue when I built my own app. That is when I add more than 10 object inside the view. It start getting lag and sometimes crashed. I also download your sample app and everything seems fine. So I make my code almost as same as yours. But the problem is still there. Could you give my some advice or how you make your app's performance better?

Hi, i found your great Project and was amazed how quick this leads to cool looking results. After fiddling around a bit i was wondering how to apply a force to views. I want them to "fall" into the middle of the screen like there is the center of a huge mass. I'm trying to misuse the gravity property to simulate a force, but it would be nice to have an interface to the "bodys" of the box2d entitys.

Thanks for you work :)

Hi, my name is Eduardo and i have been trying to figure out a way to set a onClickListener on a PhysicsLayout child view to change its background color. The thing is, when i do, all the physics behaviour stop working. Do you have any suggestions that could help me?

Sorry if this is a obvious question, i am just starting android developing :P

There is alot of lag in the github sample where as i can add multiple views without any lag in the sample on Google Play without any lag.

why is that?

I'm working on scaling the objects within physics layout.When scale objects their radius does not change and the view goes beyond boundaries. Is there any way to change the radius of already added view in the layout?

I imitated your project, but the two balls did not collide with each other. This is the project I wrote, can help me find https://github.com/xufeifandj/Ball

Added gravity to a point in the world with optional gravitation to the captured view at a definable speed

Gesture detector to allow easy single, double and long clicking on added views

Testing out this great library, and was a little puzzled when different DPI phones had boundaries at different positions.

I've been able to set this myself using setPixelsPerMeter but I think it would be a great default if 50 was replaced by 50/3 * density (since most phone densities today are 3 or 4)

Hi, Thanks for your great lib.

Is there anyway to set layout_fixedRotation dynamically? I want to add an inflated view to PhysicsRelativeLayout in runtime, but i cannot set this feature for the inflated view. how can I do that?

Thanks in advance.

Hello. I have imported your lib in my app and am using its 'statik' feature for drag & drop ImageViews. It is a great library, thank you :)

My question is: Is there a way to detect where user drops the object?

Edit: When I use this code to detect user's touch release, the object (ball) doesn't move anymore:

ball.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                if(event.getAction() == MotionEvent.ACTION_UP)
                    Toast.makeText(MainActivity.this, "Dropped.", Toast.LENGTH_SHORT).show();
                return true;
            }
        });

I've experimented with a number of different ways to intercept the touch events, but I cannot seem to figure out how to enable fling when the PhysicsFrameLayout is in a NestedScrollView, and be able to drag the views inside it vertically.

I can drag them horizontally fine, but as soon as I start dragging vertically I get an ACTION_CANCEL MotionEvent, and my dragging of the view inside the PhysicsFrameLayout stops.
