I want the image view picture to go all the way down to the screen, but there is a margin at the bottom and I don't know where it's coming from. 我希望图像查看图片一直向下到屏幕,但是底部有一个空白,我不知道它来自哪里。 I thought it might be the image dimensions, but even setting to 1000x1000 pixels doesn't do anything to get rid of the margins, neither does setting alignParentBottom. 我以为可能是图像尺寸,但是即使将其设置为1000x1000像素也无法消除空白,设置alignParentBottom也是如此。
Here is a screenshot: 这是屏幕截图:
Does the image you are using match the dimensions of the screen? 您使用的图像是否与屏幕尺寸匹配?
If not: 如果不:
Try setting android:scaleType="fitXY"
on the ImageView
- This will scale the image to fit the screen but will not retain the images original aspect ratio. 尝试在ImageView
上设置android:scaleType="fitXY"
-这将缩放图像以适合屏幕,但不会保留图像的原始宽高比。
If you want to maintain the aspect ratio android:scaleType="center"
will center the image with no scaling and maintains aspect ratio. 如果要保持宽高比,则android:scaleType="center"
将使图像居中而不缩放,并保持宽高比。 However it will crop the image if it is larger than the screen, or it will not fill the screen if it is too small. 但是,如果图像比屏幕大,则会裁切图像;如果图像太小,则不会填满屏幕。
