Re: [android-developers] Landscape Portrait and more... advanced question

to draw the circle on touch with the finger use this code this is with the gesture listener


public class GesturesActivity extends Activity implements OnGesturePerformedListener {
    private GestureLibrary mLibrary;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        mLibrary = GestureLibraries.fromRawResource(this, R.raw.spells);
        if (!mLibrary.load()) {
            finish();
        }

        GestureOverlayView gestures = (GestureOverlayView) findViewById(R.id.gestures);
        gestures.addOnGesturePerformedListener(this);
    }
   
    public void onGesturePerformed(GestureOverlayView overlay, Gesture gesture) {
        ArrayList<Prediction> predictions = mLibrary.recognize(gesture);

        // We want at least one prediction
        if (predictions.size() > 0) {
            Prediction prediction = predictions.get(0);
            // We want at least some confidence in the result
            if (prediction.score > 1.0) {
                // Show the spell
                Toast.makeText(this, prediction.name, Toast.LENGTH_SHORT).show();
            }
        }
    }
}

// TODO Auto-generated method stub

super.onDraw(canvas);

Paint paint = new Paint();

paint.setColor(Color.RED);

//canvas.drawLine(x, y, x+20, y+20, paint);
