我正在尝试在 android 中翻译和旋转位图ImageView。但我无法得到结果。任何指针都会有所帮助。

    int width = mb.getWidth();
    int height = mb.getHeight();

    // create a matrix for the manipulation
    Matrix matrix = new Matrix();
    matrix.preTranslate(width/2, height/2)
    matrix.postRotate(angle);
    Bitmap resizedBitmap = Bitmap.createBitmap(mb, 0, 0,
                      width, height, matrix, true);
    imageview.setImageBitmap(resizedBitmap);
