我希望用户从画面中选择一个照片。 由于大多数照片的体积非常大,我想将其扩大到最适当的宽度。 当我只了解情况的道路时,是否有办法这样做?
例如,如果您的比图有影响,那么《图像评论》就是框架。 照片:
int iWidth=bmp.getWidth();
int iHeight=bmp.getHeight();
Display display = getWindowManager().getDefaultDisplay();
DisplayMetrics dm = new DisplayMetrics();
display.getMetrics(dm);
int dWidth=dm.widthPixels;
int dHeight=dm.heightPixels;
float sWidth=((float) dWidth)/iWidth;
float sHeight=((float) dHeight)/iHeight;
if(sWidth>sHeight) sWidth=sHeight;
else sHeight=sWidth;
Matrix matrix=new Matrix();
matrix.postScale(sWidth,sHeight);
newImage=Bitmap.createBitmap(bmp, 0, 0, iWidth, iHeight, matrix, true);
framePhoto.setImageBitmap(newImage);
