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);
