@HoussemHfaidh i use for this Matrix

If it helps, I wait until after the sticker is added, in a StickerView.OnStickerOperationListener, and then adjust its matrix:

@Override public void onStickerAdded(@NonNull Sticker sticker) {
    // you provide desired_w, desired_h, desired_left, desired_top
    sticker.setMatrix(freshInsetMatrix(desired_w, desired_h, desired_left, desired_top));
  }

  private Matrix freshInsetMatrix() {
    float sticker_w = inset_sticker.getWidth();
    float sticker_h = inset_sticker.getHeight();

    float scale_x = desired_w / sticker_w;
    float scale_y = desired_h / sticker_h;

    Matrix matrix = new Matrix();
    matrix.postTranslate(desired_x / scale_x, desired_y / scale_y);
    matrix.postScale(scale_x, scale_y);
    return matrix;
  }
