Change color of bitmap by color Transform Matrix not working

Question

In the following I am trying to change color of of Ic_Launcher image by using color transform matrix method. While it works for red static matrix present in the code its not working for other colors that I am trying to convert form hex code to ARGB and finally the color transform matrix. something wrong in my code?

 @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Bitmap icon = BitmapFactory.decodeResource(this.getResources(),
            R.drawable.ic_launcher);
    ImageView iv=(ImageView)findViewById(R.id.imageView);

    changeBitmapColor(icon,iv);


}

public void changeBitmapColor(Bitmap sourceBitmap,ImageView iv){


    float[] colorTransformRed = {
            0, 1f, 0, 0, 0,
            0, 0, 0f, 0, 0,
            0, 0, 0, 0f, 0,
            0, 0, 0, 1f, 0
    };




    float[] colorTransform=rgbToFloatArray(hexToRGBArray("FF00FF"));

    ColorMatrix colorMatrix = new ColorMatrix();
    colorMatrix.setSaturation(0.0f); //Remove Colour
    colorMatrix.set(colorTransform); //Apply the new color

    ColorMatrixColorFilter colorFilter = new ColorMatrixColorFilter(colorMatrix);
    Paint paint = new Paint();
    paint.setColorFilter(colorFilter);

    Bitmap resultBitmap = Bitmap.createBitmap(sourceBitmap, 0, (int)(sourceBitmap.getHeight() * 0.15), sourceBitmap.getWidth(), (int)(sourceBitmap.getHeight() * 0.75));

    iv.setImageBitmap(resultBitmap);
    Canvas canvas = new Canvas(resultBitmap);
    canvas.drawBitmap(resultBitmap, 0, 0, paint);




}

           k * R, l * G, m * B, n * A, o,
           p * R, q * G, r * B,s*A , t
   };







    return tm;
}

    float[]rgb=new float[4];

    int color = (int)Long.parseLong(hex, 16);
    float r=   (color >> 16) & 0xFF;
    float g= (color >> 8) & 0xFF;
    float b=  (color >> 0) & 0xFF;
    float a= (color >> 24) & 0xFF;
