予有在主体上的背景图像。 我想实现的是:
I have a background image in body. What I want to achieve is that:
1) - 计算访问者的屏幕分辨率。 2) - 根据该决议我要调整我的背景图片
1) - Calculate the visitor screen resolution. 2) - based on that resolution I want to resize my background image.
我知道拿到的屏幕分辨率为
I know get the screen resolution as a
Display display = getWindowManager().getDefaultDisplay();
width_screen = display.getWidth();
height_screen = display.getHeight();
但我不知道该如何调整,根据用户的屏幕分辨率的图片。
But I don't know how to resize the images according screen resolution of user.
谁能帮助? 谢谢..
Can anyone help? Thanks..
将一个ImageView的布局中的文件,并设置
Put a ImageView in your layout file and set
android:layout_width="match_parent"
android:layout_height="match_parent"
如果你想保持方面使用:
If you want to keep the aspect use:
android:scaleType="centerInside"
如果你不关心的宽高比使用:
If you dont care about the aspect ratio use:
android:scaleType="fitXY"
