Question

I want to implement drag and drop in android 4.1, for that i want to place my icons image views in circular manner around a center point. (with image view i can implement drag and drop perfectly, with bitmap its somewhat complex)

I tried with bitmaps and paint but it is not as smooth, as we can get in android 4.1.

Is there any method or way in android 4.1 by which i can place the imageviews in circular manner by giving the radius of the circle and number of sections it will get divide, its like a math question ?

Take a look at this link for drag and drop.

Thanks in advance for help.

Answer 1

I have implemented by using Math in android.

I am sharing a part of my code:

double xOffset = currentRadius * Math.cos(Math.toRadians(d));
double yOffset = currentRadius * Math.sin(Math.toRadians(d));
