在Android自定义键盘中设置键盘模式

Question

我已经使用Android键盘类创建了自定义键盘。

我想要有两种模式的行。一种是正常模式。一个是当用户按下“Sym”按钮时。对于每个Keyboard.Row在XML中的“Sym”按钮，我已经指定了android：keyboardMode =“@ + id/sym”。

现在，当我运行它只有没有指定android：keyboardMode显示的行。这正如预期的那样以及文档所述。

我的问题是如何在我的代码中设置模式，以便android：keyboardMode =“@ + id/sym”的行得到渲染？

<Row> 
    <Key android:codes="113" android:keyLabel="q" /> 
    <Key android:codes="119" android:keyLabel="w" /> 
    <Key android:codes="101" android:keyLabel="e" /> 
    <Key android:codes="114" android:keyLabel="r" /> 
    <Key android:codes="116" android:keyLabel="t" /> 
    <Key android:codes="121" android:keyLabel="y" /> 
    <Key android:codes="117" android:keyLabel="u" /> 
    <Key android:codes="105" android:keyLabel="i" /> 
    <Key android:codes="111" android:keyLabel="o" /> 
    <Key android:codes="112" android:keyLabel="p" /> 
    <Key android:codes="-5" android:keyIcon="@drawable/keyboard_backspace_icon" android:keyWidth="91dp" /> 
</Row> 
<Row android:keyboardMode="@+id/sym"> 
    <Key android:codes="113" android:keyLabel="+" /> 
    <Key android:codes="119" android:keyLabel="_" /> 
    <Key android:codes="101" android:keyLabel="=" /> 
    <Key android:codes="114" android:keyLabel="%" /> 
    <Key android:codes="116" android:keyLabel="^" /> 
    <Key android:codes="121" android:keyLabel="|" /> 
    <Key android:codes="117" android:keyLabel="&lt;" /> 
    <Key android:codes="105" android:keyLabel=">" /> 
    <Key android:codes="111" android:keyLabel="[" /> 
    <Key android:codes="112" android:keyLabel="]" /> 
    <Key android:codes="-5" android:keyIcon="@drawable/keyboard_backspace_icon" android:keyWidth="91dp" /> 
</Row>

好吧，自己弄明白了。

没有简单切换键盘模式的方法。你必须做的是创建2个不同的键盘并手动切换它们。

下面是更新后的XML的样子。请注意，您希望在这两个关键字中使用的行不应包含标志android：keyboardMode。

<!-- this is the row that shows in both modes --> 
<Row android:keyWidth="51dp"> 
    <Key android:codes="49" android:keyLabel="1" /> 
    <Key android:codes="50" android:keyLabel="2" /> 
    <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="55" android:keyLabel="7" /> 
    <Key android:codes="56" android:keyLabel="8" /> 
    <Key android:codes="57" android:keyLabel="9" /> 
    <Key android:codes="48" android:keyLabel="0"/>   
</Row> 

<!-- this is the normal mode --> 
<Row android:keyboardMode="@integer/keyboard_normal"> 
    <Key android:codes="113" android:keyLabel="q" /> 
    <Key android:codes="119" android:keyLabel="w" /> 
    <Key android:codes="101" android:keyLabel="e" /> 
    <Key android:codes="114" android:keyLabel="r" /> 
    <Key android:codes="116" android:keyLabel="t" /> 
    <Key android:codes="121" android:keyLabel="y" /> 
    <Key android:codes="117" android:keyLabel="u" /> 
    <Key android:codes="105" android:keyLabel="i" /> 
    <Key android:codes="111" android:keyLabel="o" /> 
    <Key android:codes="112" android:keyLabel="p" /> 
    <Key android:codes="-5" android:keyIcon="@drawable/keyboard_backspace_icon" android:keyWidth="91dp" /> 
</Row> 

<!-- this is the symbol mode--> 
<Row android:keyboardMode="@integer/keyboard_symbol"> 
    <Key android:codes="113" android:keyLabel="+" /> 
    <Key android:codes="119" android:keyLabel="_" /> 
    <Key android:codes="101" android:keyLabel="=" /> 
    <Key android:codes="114" android:keyLabel="%" /> 
    <Key android:codes="116" android:keyLabel="^" /> 
    <Key android:codes="121" android:keyLabel="|" /> 
    <Key android:codes="117" android:keyLabel="&lt;" /> 
    <Key android:codes="105" android:keyLabel=">" /> 
    <Key android:codes="111" android:keyLabel="[" /> 
    <Key android:codes="112" android:keyLabel="]" /> 
    <Key android:codes="-5" android:keyIcon="@drawable/keyboard_backspace_icon" android:keyWidth="91dp" /> 
</Row> 

然后创建一个integer.xml

<?xml version="1.0" encoding="utf-8"?> 
<resources> 
    <integer name="keyboard_symbol">1</integer> 
    <integer name="keyboard_normal">0</integer> 
</resources> 

下面是相关的Java代码。当您创建Keyboard对象时，您将传递keyboard_normal或keyboard_symbol。

normalKeyBoard = new Keyboard(activity, R.id.board, R.integer.keyboard_normal); 
symbolKeyBoard = new Keyboard(activity, R.id.board, R.integer.keyboard_symbol); 

现在创建一个类变量来跟踪模式。默认值是R.integer.keyboard_normal

private int mKeyboardState = R.integer.keyboard_normal; 

现在，在您onKeyboardActionListner（）。安其方法把代码捕捉切换模式（假设你已经在你的键盘创建一个）的关键。

 if(primaryCode== Keyboard.KEYCODE_MODE_CHANGE) { 
      if(mKeyboardView != null) { 
       if(mKeyboardState == R.integer.keyboard_normal){ 
        //change to symbol keyboard 
        if(symbolKeyBoard== null){ 
         symbolKeyBoard = new Keyboard(mHostActivity, R.xml.hexkbd, R.integer.keyboard_symbol); 
        } 

        mKeyboardView.setKeyboard(symbolKeyBoard); 
        mKeyboardState = R.integer.keyboard_symbol; 
       } else { 
        if(normalKeyBoard== null){ 
         normalKeyBoard = new Keyboard(mHostActivity, R.xml.hexkbd, R.integer.keyboard_normal); 
        } 

        mKeyboardView.setKeyboard(normalKeyBoard); 
        mKeyboardState = R.integer.keyboard_normal; 
       } 
       //no shifting 
       mKeyboardView.setShifted(false); 
      } 
     }
