I am trying to program an androd application where if there is input on two places of the screen in sucsession then it will draw a line between the two points. I have already set up "X" and "Y" values that work and columns and rows are defined by the "X" and "Y" values. After those i have an IF statement that needs to draw a line between the two points. Say if column one and row two are selected and then colum one and row three are selcted I want a line to be drawn between the two points. Also I am not totally sure how to use the MotionEvent stuff or how to put the touch actions into the IF statement.
final View touchView = findViewById(R.id.touchView);
touchView.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
String.valueOf(event.getX() + String.valueOf(event.getY()));
double c = event.getX();
double column = Math.floor(event.getX()/(480/12));
double r = event.getY();
double row = Math.floor(event.getY()/(630/12));
if (column == 0 && row == 2 //there should be more stuff here
) {
//I dont know how to draw a line in here, please help
}
return true;
}
});
}
