I thought you were using an image of an arrow?
I would put a breakpoint here:
screenW = w;
Make sure screenW and screenH are getting set correctly.

Yes, I ran it. It works fine if you make the change I told you to make:
*change this:*
*
*
*Y = initialY;*
*
*
*to this:*
*
*
* Y = (int) (screenH /2) - (arrowH / 2) ;*

Hai bob thanks for your reply...
I made the change as you said... *

But still the same results.
And here is some screen shot of my results at central position left and
right
If you want the image in the center of the screen, change this:
Y = initialY;
to this:
* Y = (int) (screenH /2) - (arrowH / 2) ;*

I am trying an application like rotating image with motion sensorMy
problem is that the image does not rotate about centre properlyAnd my
angle range is 0 to 90 and 0 to -90..
Well, for one thing, this is not right:
canvas.rotate(angle, X + getWidth() 1, Y + getHeight() 1);
You should be calling getWidth and getHeight on the bitmap.
Something like this:
canvas.rotate(angle, X + resizedBitmap.getWidth()/2, Y +
resizedBitmap.getHeight()/2);

Hai bob thanks for reply.
I made the above change in my code but still the same resultAnd my
image get distorted it's edges while rotation..

import android.app.Activity;

I think you should be doing something like this:
canvas.setMatrix(matrix);

Hai thanks for the replys
I changed my code like
matrix.postScale(scaleWidth, scaleHeight);
matrix.postRotate(angle, X+centrex , Y+centrey );
canvas.setMatrix(matrix);
Bitmap resizedBitmap = Bitmap.createBitmap(arrow, 0, 0,
arrow.getWidth(),
13 matches
