Question

Hi I wrote this code, and I dont understand why give me syntax error on token "}", delet this token?

private class DemoView extends View{
        public DemoView(Context context) {
            super(context);
            // TODO Auto-generated constructor stub
        }//here***

        final int x = 0;
        final int y = 0;

this.setOnTouchListener(new View.OnTouchListener(){
            public boolean onTouch(View v, MotionEvent e){
                switch(e.getAction()){
                case MotionEvent.ACTION_DOWN:
                    x++;
                    break;
             case MotionEvent.ACTION_MOVE:   // touch drag with the ball
                // move the balls the same as the finger
                    x = x-25;
                    y = y-25;   
                    break;
                }
                return true;
            }//here***
         }   

Thanks

Multiple errors:

1. First closing curly brace closed the constructor. Should be at the end of code.
2. setOnTouchListener() missed the closing brace.
3. You variables x,y should be fields (instead of automatic variables) so that they can be changed inside anonymous class View.OnTouchListener

Here is the corrected code (I hope it does what you intended):

public class DemoView extends View {

    int x = 0;
    int y = 0;

    public DemoView(Context context) {
        super(context);


        this.setOnTouchListener(new View.OnTouchListener() {
            public boolean onTouch(View v, MotionEvent e) {
                switch (e.getAction()) {
                    case MotionEvent.ACTION_DOWN:
                        x++;
                        break;
                    case MotionEvent.ACTION_MOVE:   // touch drag with the ball
                        // move the balls the same as the finger
                        x = x - 25;
                        y = y - 25;
                        break;
                }
                return true;
            }//here***
        });
    }
}
