<Keyboard xmlns:android="http://schemas.android.com/apk/res/android"

How can I add Gmail , Hotmail , ... to the fist row of my keyboard ? I also want to add a sound when the user click on any key like the default android keyboard how can I do that ?

回答1:

Create XML like this for keyboard :

<?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>

And style is as below:

 <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>

In which

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

is used to set background for key.

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

is used for text color of key.

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

is used to set background of entire keyboard and

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

is uesd to set preview of key.

Preview layout 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"/>

For spaces between keys use this.

And for android:background="@drawable/neon_candidate_middle_pressed" it is background image which you want to show in preview of key.
