                android:text="@string/aStr" />
        </TableRow>
    </TableLayout>

</RelativeLayout>

的strings.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>

    <string name="fStr">Fffffffff</string>
<string name="rStr">Rrrrrr</string>
<string name="sStr">Ssssss       </string>
<string name="lStr">Lllll</string>
<string name="oStr">Oooooooooooo</string>
<string name="tStr">Ttttt</string>
<string name="eStr">Eeeeee</string>
<string name="dStr">Dddddddddd</string>
<string name="cStr">Cccccccc</string>
<string name="hStr">Hhhh</string>
<string name="aStr">Aaaaaaaaaa aaaa</string>

</resources>

此应用有2个问题。

按钮图像和文字之间的差距太大
当应用程序处于水平视图时，整个对齐方式都会混乱，并显示如下。

enter image description here

如您所见，没有文字！

我该如何解决这个问题？

Answer 1

在名为layout-land的res文件夹下创建一个新文件夹，并将您的布局（XML文件）放在该文件夹中。

请参阅此doc

Answer 2

试试这个..将表格行width设为match_parent，将height设为wrap_content并删除weight。然后，如果您提供weight某些内容，则需要为0dp或height

提供width

Answer 3

这个问题是由于图像的大小如果你拍摄小尺寸的图像然后你遇到这个问题.....如果你想要放大尺寸的图像然后你必须将RelativeLayout更改为ScrolView 然后TableLayout的高度应该是wrap_content .....

当水平显示应用程序时，按钮对齐消失
