Android :: Drawing Canvas With Given Matrix Transformation?

I got this code from another post and modified it to work for me as a TextView. I tried using the code below but no transformation is happening? I trying to draw the canvas of the TextView with the given Matrix transformation.

import android.content.Context; import android.graphics.Canvas; import android.graphics.Matrix; import android.util.AttributeSet; import android.view.MotionEvent; import android.widget.TextView;
public class CTextView extends TextView { private Matrix mForward = new Matrix(); private Matrix mReverse = new Matrix(); private float[] mTemp = new float[2];
public CTextView(Context context) { super(context); mForward.postRotate(90); mForward.invert(mReverse); } public CTextView(Context context, AttributeSet attrs) { super(context, attrs);
mForward.postRotate(90); mForward.invert(mReverse); } public CTextView(Context context, AttributeSet attrs, int defStyle) { super(context, attrs, defStyle);
mForward.postRotate(90); mForward.invert(mReverse); }
@Override protected void dispatchDraw(Canvas canvas) { canvas.save(); canvas.concat(mForward); canvas.restore(); super.dispatchDraw(canvas); }
@Override public boolean dispatchTouchEvent(MotionEvent event) { final float[] temp = mTemp; temp[0] = event.getX(); temp[1] = event.getY();
mReverse.mapPoints(temp); event.setLocation(temp[0], temp[1]); return super.dispatchTouchEvent(event); }
