的strings.xml

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

<string name="cStr">Cccccccc</string>
<string name="hStr">Hhhh</string>
<string name="aStr">Aaaaaaaaaa aaaa</string>

</resources>

此应用有问题。

1. 按钮图像和文本之间的差距太大，特别是在5.1 WVGA屏幕中。它在我的手机中看起来相同，屏幕尺寸为4.5英寸

以下是图片



我该如何解决这个问题？

也许使用LinearLayout;

Answer 2

尝试使用android：drawablePadding，以及android：paddingLeft和android：paddingRight

参考android:drawableLeft margin and/or padding

这是一个修改后的版本，它会缩小按钮的大小，并将它们放在行内，并摆脱无用的RelativeLayout父级（因为Lint可能指向你）：
