问题描述
现在我的登录按钮,比我的应用程序名称的文字更广泛,因为它使用了相对布局的固定填充,但我希望它会自动扩大与应用程序名称文本的左边和右边边排队。有没有什么方法以编程方式做到这一点?
Right now my Log In button is wider than my app name text because it uses fixed padding of the relative layout, but I want it to automatically widen to line up with the left and right edges of the app name text. Is there any way to programmatically do this?
我希望它看起来相同的所有设备。我担心如果我只是硬code我自己的空间,这将右看看我的设备上,但可能不右看看在其他设备上,如果他们提供的字体不同。
I want it to look the same on all devices. I'm afraid that if I just hard-code my own margins, it will look right on my device, but might not look right on other devices if they render the fonts differently.
谢谢!

推荐答案
我不能完全肯定这是否会有所帮助,但让我试试看。
I am not entirely sure if this would help, but let me give it a try.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<TextView
android:id="@+id/title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:text="App\nTitle" />
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignLeft="@id/title"
android:layout_alignRight="@id/title"
android:layout_below="@id/title"
android:text="Log In" />
</RelativeLayout>
然而,该按钮将是一样宽的TextView的,它可能没有足够的宽以显示其自己的文本
However, the button would be just as wide as the textview, it may not be wide enough to display its own text.
