</Keyboard>

我得到以下信息

忽略第一行，我怎样才能使键盘按钮背景像第一张照片一样我的意思是我想让我的键盘像第一行一样具有所有细节？ 如何将 Gmail、Hotmail 等添加到键盘的第一排？ 当用户单击任何键（例如默认的 android 键盘）时，我还想添加声音 我怎样才能做到这一点 ？

Answer 1

为键盘创建这样的 XML：

<?xml version="1.0" encoding="utf-8"?>
<com.YourKeyboardView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/keyboard"
    style="@style/keyboard_1_style"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content" >

</com.YourKeyboardView>

样式如下：

 <style name="keyboard_1_style">
        <item name="android:keyBackground">@drawable/k1_selector</item>
        <item name="android:keyTextColor">#24B2E7</item>
        <item name="android:background">@android:color/white</item>
        <item name="android:keyPreviewLayout">@layout/k1_preview</item>
 </style>

其中

<item name="android:keyBackground">@drawable/k1_selector</item>

用于设置键的背景。

<item name="android:keyTextColor">#24B2E7</item> 

用于键的文本颜色。

<item name="android:background">@android:color/white</item> 

用于设置整个键盘的背景和

<item name="android:keyPreviewLayout">@layout/k1_preview</item>

用于设置按键预览。

预览布局 xml：

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textSize="40sp"
    android:textColor="@android:color/white"
    android:gravity="center"
    android:background="@drawable/neon_candidate_middle_pressed"/>

键之间的空格使用this。

对于android:background="@drawable/neon_candidate_middle_pressed"，它是您要在密钥预览中显示的背景图像。
