Moving an Android Button depending on where is the AR.

August 31, 2012 - 2:53am #1

Hi,

I would like the user of my application to click on AR.

For that, i have been able to get in Java the coordinates of the AR (from the function renderFrame in the matrix modelViewProjection (data[12] and data[13]).

But I can't move the Android button (even with setHeight / setLeft / setBottom).

_dynamicButton.setClickable(true);<br />                _dynamicButton.setOnClickListener(listenerInfoApplicationButton);<br />                _dynamicButton.setText("x="+coordAR[0]+" y="+coordAR[1]);<br />                _dynamicButton.setLeft(coordAR[0]*200);<br />                _dynamicButton.setHeight(coordAR[0]);

The text of the button is ok, it changes but the button does'nt move...

Any idea?

Thanks in advance

I think you can "hack" it by using margins. Set button in a relative layout top left then change the margins depending on where the trackable is

eg:

setLeftMargin(trackable x position in screen space)

set topMargin(trackably y position in screen space)

This is a hacky way of doing its what i ususally use for most of my positioning problems.

Is the button in a layout? If so, perhaps its position is contrained.
