Android-自定义数字小键盘

先看界面布局文件

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <EditText
        android:id="@+id/edit"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content" />

    <EditText
        android:id="@+id/edit1"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:password="true" />

    <RelativeLayout
        android:layout_width="fill_parent"
        android:layout_height="wrap_content" >

        <android.inputmethodservice.KeyboardView
            android:id="@+id/keyboard_view"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_alignParentBottom="true"
            android:focusable="true"
            android:focusableInTouchMode="true"
            android:background="@color/lightblack"
            android:keyBackground="@drawable/btn_keyboard_key"
            android:keyTextColor="@color/white"
            android:visibility="gone" />
    </RelativeLayout>

</LinearLayout>

通过布局文件可以看出界面上有两个输入框，其中一个是密码输入框，界面上还有一个隐藏的键盘控件。
在res下新建xml文件夹，在xml文件夹中新建qwerty.xml和symbols.xml文件. qwerty.xml 是字母键盘布局，symbols.xml 是数字键盘布局，内如如下

先上图吧：

最近在做一个优惠券的项目，上面的截图就是一个商家使用的一个平板的客户端，一开始的时候是使用系统默认的输入法来输入用户的手机号，但考虑到系统默认的输入法数字太小，而且这个功能只需要输入数字就可，为了简化商家的操作，加快商家发放优惠券的速度，就写了这么一个数字小键盘！希望对有这方面需求的朋友能有点用，呵呵，废话不多说了，直接上代码：

先上xml文件：

<?xml version="1.0" encoding="utf-8"?>
 <!-- 投放优惠券 -->
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_width="wrap_content" android:layout_height="wrap_content"
 android:orientation="vertical" android:background="@drawable/toufang_bg">
 <TextView android:layout_width="wrap_content"
  android:textColor="#000000" android:textSize="35px" android:textStyle="bold"
  android:layout_height="wrap_content" android:text="手机号：" />
