Question

I would like to find out how can I convert touch coordinate that I get in float form to an integer. I am pretty new to java programming and android. I want to define a rectangle around my touch area and then use something like this:

    Rect touchArea = new Rect();   //I have only float coordinates to define this rect
    Rect predefinedRect = new Rect(); //This rect is defined with integers
    if(touchArea.intersect(predefinedRect)){
        //do something
    }

Also there isn’t method like Rect(RecF), at least I haven’t found one. So what could I do to use that .intersect() method?

Answer 1

There is a RectF constructor that takes a Rect. So you could use that and then use the intersect in the RectF class.

If you want to convert float to int you could just do

int i = (int)1.5;
// i = 1

but be careful with how the float just gets cut and not rounded.
