Android onTouchEvent error, ";" expected

Hi there,

I'm now trying to mastering OpenGL for mobile gaming, so I'll need to ask a boxes of question about it. Here's my current problem now.

Specification :
- android SDK API 6 (android 2.1)
- using command line to create new project, build, and install
- using emulator (AVD) to run program
- Windows 7 Pro SP 1 32x

I'm trying to rotate triangle in my android on touch (onTouchEvent).
Here's my code snippet :

package .....;
import android.app.Activity;
import android.content.Context;
import android.opengl.GLSurfaceView;
import android.os.Bundle;
import android.view.MotionEvent;
import android.view.View;

import javax.microedition.khronos.egl.EGLConfig;
import javax.microedition.khronos.opengles.GL10;

public class segitiga extends Activity{
..
..
..
..
}

class HelloOpenGLES10SurfaceView extends GLSurfaceView {
...
...
...
public HelloOpenGLES10SurfaceView(Context context){
...
...
@Override 
    public boolean onTouchEvent(MotionEvent e) {
   
        float x = e.getX();
        float y = e.getY();
        
        switch (e.getAction()) {
            case MotionEvent.ACTION_MOVE:
    
                float dx = x - mPreviousX;
                float dy = y - mPreviousY;
    
                // reverse direction of rotation above the mid-line
                if (y > getHeight() / 2) {
                  dx = dx * -1 ;
                }
    
                // reverse direction of rotation to left of the mid-line
                if (x < getWidth() / 2) {
                  dy = dy * -1 ;
                }
              
                mRenderer.mAngle += (dx + dy) * TOUCH_SCALE_FACTOR;
                requestRender();
        }

        mPreviousX = x;
        mPreviousY = y;
        return true;
    }  

}
}

The porblem is when I tried to compile (install debug / adb installd ) to my emulator it's throw me error like this on the line of :

public boolean onTouchEvent(MotionEvent e)

It need ";" after onTouchEvent and after "e". So it should be this like according to the compiler :

public boolean onTouchEvent;(MotionEvent e;)

And that's wrong things.
How should I fixe it?

Thanks in advances
