Question

I have a app that shows the camera view on the screen on a FrameLayout. The screen is in fixed LandScape mode.

I need to write a textView with dynamically determined coordinates of the screen. The coordinates are determined in percentages, for example :

write the textview on the coorinates x=80% of the screen & y=20% of the screen. write the textview on the coorinates x=35% of the screen & y=55% of the screen.

how to do it? i already have the percentages, i only need to know how to use them to write the textview on the desired position of the frameLayout

code examples are welcome

i tried with this but doesn’t works, the textview isn’t moved:

TextView poi..... etc etc
poi.setLayoutParams(new LayoutParams((int)(w*(xCoordPercent/100)), h/2));

thanks

Answer 1

MarginLayoutParams params=(MarginLayoutParams )poi.getLayoutParams();
params.leftMargin=80;
//here 100 means 100px,not 80% of the width of the parent view
//you may need a calculation to convert the percentage to pixels. 
params.topMargin=50;
poi.setLayoutParams(params);

This may help.
