GridLayout在小显示屏上折叠

Leo*_*rak 9 android android-layout

我LinearLayout用TextView,GridLayout而另一个TextView.它可以在许多现代手机和平板电脑上正确显示,但在像Nexus S这样的小型显示屏上完全失败.请参阅下面的图片.

我试图减小字体大小,删除9补丁背景,甚至删除所有边距.当有一些边缘时,我只能看到digit7.然后我最小化了它们,我可以看到第一个按钮的四行,它是渲染的两倍.我不明白为什么,它应该有wrap_content宽度.

我试图最小化代码并将其缩小为GridLayout单行,但仍然不适合屏幕的宽度.

那里发生了什么？

更新:

420x800 mdpi工作
420x800 hdpi坏了
540x920 hdpi的作品
720x1280 hdpi工作

更新2:

当字体为38sp或更大时,Nexus 5x也有同样的问题.有趣的是,Studio的设计器显示正确的布局,但设备/模拟器都显示损坏的视图和跟随错误:

D/android.support.v7.widget.GridLayout: vertical constraints: y1-y0>=197, y2-y1>=197, y3-y2>=197, y4-y3>=197, y4-y0<=785 are inconsistent; permanently removing: y4-y0<=785.

Manjunath Prabhakar说,麻烦可能与体重有关.所以我试图删除所有权重属性,现在布局更有意义.我还没修好它.我会考虑将布局重写为嵌套的LinearLayouts作为后退,因此我会为其他建议提供赏金.

我想这是支持版本的bug GridLayout.

看看这个(目前是Assigned):我认为这与你关于Nexus 5X字体大小行为的问题有关.一般来说,我在这里发现了很多相关的错误(与GridLayout宽度测量有关).

我会尝试给你一个解决方法.

我正在使用com.android.support:gridlayout-v7:25.1.1.

我认为您可以通过这种方式解决您的布局问题(旧手机中的对齐和Nexus 5X中的字体大小):

基本上,我所做的是将每组按钮(除了最后一行之外的四个按钮)包装在一个LinearLayout.

在这里你可以看到它在两部手机中的外观:

Nexus 5

三星galaxy核心加(旧)

如您所见,最后一行的对齐存在问题.我认为你可以尝试解决这些按钮与属性和属性的对齐.如果您想在最后一个主题中进一步改进,请告诉我.

希望这可以帮助.
