如何在键盘布局上的键前留一个空格？
如何在键盘布局上的键前留一个空格？
提问于 2019-11-26 01:43:02
我在Android上开发了一个自定义键盘应用程序。现在，我的键盘看起来像这样：
我喜欢做的是在左边为第一个键留出一些空间，在右边为行中的最后一个键留出一些空间。换句话说，我想把键放在行的中央。它需要是这样的：
我试过使用不同的android:keyWidth设置，还有android:horizontalGap，但它们都不适用于这个特定的设计决定。
我的keys_layout_dark_theme文件。我有三个不同的主题，所以只有一个和另一个之间的变化是颜色，图标。
<?xml version="1.0" encoding="utf-8"?>

您应该在行或keys中添加android:verticalGap和android:horizontalGap属性。
它看起来或多或少如下所示：
<Row android:verticalGap="1%p"
android:horizontalGap="0.5%p">在创建自定义键盘布局时，还有一些属性可以帮助您。看看这个question。
如果只想在一侧留出页边距，请组合使用edgeFlags和gap属性：
<Key android:keyEdgeFlags="left" gap="1%p"/>否则，如果您不想使用它，也有两个变通方法:第一个选项是为图像中有空格的键添加自定义可绘制，第二个选项是添加一个空键，并使用空键的android:horizontalGap设置边距的大小。
