I have an ImageView for which I want to pass float values as Top and Left margin. I have these 2 values to set as Top and Left margin.

float valTop = 3.5;
float valueLeft = 6.8;

I have this code. But I have to roundup the margin values to int value.

RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT); 
        params.leftMargin = Math.round(valLeft);
        params.topMargin = Math.round(valTop);
        imageView.setLayoutParams(params);

Is there any way to directly set float value as margin ?

why `float` value? do you have any problem with `int`? – Rustam Aug 14 '15 at 08:36
You have to convert this into pixel and then set ... Try.. [this][1] [1]: http://stackoverflow.com/questions/11177009/how-to-use-dpi-scaling-factor-float-to-set-margins-int – Das Aug 14 '15 at 08:40
Its a graph. And I need to set the point in x and y axis. And I cannot set 3 for 3.5. – Ronn Aug 14 '15 at 08:40
if you really need float (????) use `View#TRANSLATION_X` / `View#TRANSLATION_Y` property – pskink Aug 14 '15 at 08:42
Can you give an example ? – Ronn Aug 14 '15 at 08:44
read the View#TRANSLATION_X/Y javadocs – pskink Aug 14 '15 at 08:46
