在设备上查看时，为什么图像部分脱离屏幕？ [英] Why is image partially out of screen when viewing on device?

问题描述

我在Android工作室添加了一张图片到我的视野中。在Android工作室的xml视图中，图像距底部约1厘米。



当我将程序加载到手机中时，图像的一半位于屏幕之外区域。



我已将视图设备设置为Nexus 5（5英寸），我的手机是Galaxy S4（也是5英寸）。所以那里应该没什么区别。



这是它在编辑器中的样子：

< img src ='http：//s15.postimg.org/4gbo4yzkn/alignemtn.jpg'border ='0'alt =alignemtn/>





提前致谢！

Hi,
i added an image in Android studio to my view. The image is about 1cm from the bottom in the xml view in Android studio.

When i load the program into my phone then half of the image is outside of the screen area.

I have set the view device to Nexus 5 (5inch) and my phone is Galaxy S4 (also 5inch). So there should be no difference there.

Here is how it looks in the editor:
<img src='http://s15.postimg.org/4gbo4yzkn/alignemtn.jpg' border='0' alt="alignemtn" />


Thanks in advance!

我有什么试过：



我试图修改各种对齐选项，但似乎没什么用。

I have tried to tinker with all kinds of alignment options but nothing seems to work.

Your relative layout contains \"fill_parent\" for height. Therefore it is trying span whole screen area. Then you have image view in \"wrap_content\". Therefore it is taking much area so that image could be shown full.

If you really want to fit all view inside display area you need to use weight_sum in parent view and and layout_weight in child view appropriately for manipulating height so that everything dynamically fits into display area, and noting goes out of screen area.
