android定义键盘示例（斗地主或跑得快的记牌器）

 

今天突然想起以前斗地主的时候老记不住牌，于是乎想到做一个记牌器，为了方便记牌，需要自己定义一个android键盘，于是学习了一下利用android.inputmethodservice.Keyboard 来自己定义了一个软键盘效果如图所示：

在测试时发现预览框里面没有显示我们输入的内容，网上查找原因和浏览源代码都找不到解决方案，然后只好逐个测试，最后发现时程序默认主题覆盖使得提示框的字体颜色和背景颜色一致，把主题去掉或换一个主题即可解决

 还有当输入框为密码框时，需要加入edit.setTransformationMethod(PasswordTransformationMethod.getInstance());否则输入显示的是明文

 

具体实现：

keycontent.xml这个文件定义了键盘的布局

<?xml version="1.0" encoding="utf-8"?>  
<Keyboard xmlns:android="http://schemas.android.com/apk/res/android"  
    android:keyWidth="25%p"  
    android:horizontalGap="0px"  
    android:verticalGap="0px"  
    android:keyHeight="50dip">  
    <Row>  
        <Key android:codes="51" android:keyLabel="3" /> 
        <Key android:codes="52" android:keyLabel="4" />  
        <Key android:codes="53" android:keyLabel="5" />  
        <Key android:codes="54" android:keyLabel="6" /> 
       <!--  <Key android:codes="57419"  
            android:keyEdgeFlags="right"  
            android:keyIcon="@drawable/ic_launcher" />  --> 
    </Row>  
    <Row>  
        <Key android:codes="55" android:keyLabel="7" />  
        <Key android:codes="56" android:keyLabel="8" />  
        <Key android:codes="57" android:keyLabel="9" /> 
        <Key android:codes="1010" android:keyLabel="10"
             android:keyEdgeFlags="right"  
             android:isRepeatable="true"   />
    </Row>  
    <Row>  
        <Key android:codes="74" android:keyLabel="J" />  
        <Key android:codes="81" android:keyLabel="Q" />  
        <Key android:codes="75" android:keyLabel="K" /> 
        <Key android:codes="65" android:keyLabel="A"
             android:keyEdgeFlags="right"  
             android:isRepeatable="true"   />
       
    </Row>  
    <Row>  
        <Key android:codes="-3" android:keyIcon="@drawable/sym_keyboard_left" />  
        <Key android:codes="1070" android:keyLabel="小王" />  
        <Key android:codes="1080" android:keyLabel="大王" /> 
        <Key android:codes="50" android:keyLabel="2" 
             android:keyEdgeFlags="right"  
             android:isRepeatable="true"   />
    </Row>  
</Keyboard>  

keyboardview.xml这个是主程序界面布局

<?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"
    > 
    <LinearLayout 
        android:orientation="horizontal"
        android:layout_width="fill_parent"
        android:layout_height="50dp"
        >
    <EditText   
        android:id="@+id/edit"  
        android:layout_width="fill_parent"  
        android:layout_height="wrap_content"
        android:singleLine="true"
        android:layout_weight="1" 
        />
    <Button 
        android:id="@+id/bt_go"
        android:layout_height="wrap_content"
        android:layout_width="fill_parent"
        android:layout_weight="2.5"
        android:text="GO"/>
     <Button 
        android:id="@+id/bt_delete"
        android:layout_height="wrap_content"
        android:layout_width="fill_parent"
        android:layout_weight="2.5"
        android:text="删除"/>
     </LinearLayout> 
     <ListView 
        android:id="@+id/lv_pai"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_weight="1"/>"
   <com.example.jipaiqi.MyKeboardView  
        android:id="@+id/keyboard_view"  
        android:visibility="gone"  
        android:focusable="true"  
        android:focusableInTouchMode="true"  
        android:layout_width="fill_parent"  
        android:layout_height="wrap_content"  
        android:layout_weight="0" />  
</LinearLayout>
