推荐答案

首先，您需要一个 keyboard.xml 文件，该文件将被放置在 RES / XML 文件夹（如果该文件夹不存在，创建它）。

First of all you will need a keyboard.xml file which will be placed in the res/xml folder (if the folder does not exist, created it).

<?xml version="1.0" encoding="utf-8"?> 
<Keyboard xmlns:android="http://schemas.android.com/apk/res/android"
    android:keyWidth="15%p"
    android:keyHeight="15%p" >

    <Row>
        <Key android:codes="1"    android:keyLabel="1" android:horizontalGap="4%p"/>
        <Key android:codes="2"    android:keyLabel="2" android:horizontalGap="4%p"/>
        <Key android:codes="3"    android:keyLabel="3" android:horizontalGap="4%p" />
        <Key android:codes="4"    android:keyLabel="4" android:horizontalGap="4%p" />
        <Key android:codes="5"    android:keyLabel="5" android:horizontalGap="4%p" />
    </Row>
    <Row>
        <Key android:codes="6"    android:keyLabel="6" android:horizontalGap="4%p"/>
        <Key android:codes="7"    android:keyLabel="7" android:horizontalGap="4%p"/>
        <Key android:codes="8"    android:keyLabel="8" android:horizontalGap="4%p" />
        <Key android:codes="9"    android:keyLabel="9" android:horizontalGap="4%p" />
        <Key android:codes="0"    android:keyLabel="0" android:horizontalGap="4%p" />
    </Row>

    <Row>
        <Key android:codes="-1"    android:keyLabel="@drawable/backspace" android:keyWidth="34%p" android:horizontalGap="4%p"/>
        <Key android:codes="100"    android:keyLabel="Enter" android:keyWidth="53%p" android:horizontalGap="4%p"/>
    </Row>
 </Keyboard>

**注意，你必须创建退格键绘制，并将其放置在res /绘制-LDPI文件夹一个非常小的尺寸（18×​​18像像素）

**Note that you will have to create the backspace drawable and place it in the res/drawable-ldpi folder with a very small size (like 18x18 pixels)

然后，在你希望它被使用（在您的TextView的是），你应该添加以下code中的XML文件：

Then in the xml file that you want it to be used (where your TextView is in) you should add the following code:

<RelativeLayout
 ...
>

        .....


        <android.inputmethodservice.KeyboardView
             android:id="@+id/keyboardview"
             android:layout_width="fill_parent"
             android:layout_height="wrap_content"
             android:layout_alignParentBottom="true"
             android:layout_centerHorizontal="true"
             android:focusable="true"
             android:focusableInTouchMode="true"
             android:visibility="gone" 
         />

        ......


</RelativeLayout>

**注意，XML文件，你将会把 android.inputmethodservice.KeyboardView 中，必须是 RelativeLayout的为了能够将 alignParentBottom =真（一般的键盘是psented在屏幕的底部$ P $）

**Note that the xml file that you will place the android.inputmethodservice.KeyboardView in, has to be RelativeLayout in order to be able to set the alignParentBottom="true" (Usually the keyboards are presented in the bottom of the screen)

然后你需要添加下面的code。在活动的的onCreate 功能处理的的TextView 要附加键盘

Then you need to add the following code in the onCreate function of the Activity that handles the TextView you want to attach the keyboard to

    // Create the Keyboard
    mKeyboard= new Keyboard(this,R.xml.my_keyboard);

    // Lookup the KeyboardView
    mKeyboardView= (KeyboardView)findViewById(R.id.keyboardview);
    // Attach the keyboard to the view
    mKeyboardView.setKeyboard( mKeyboard );

    // Do not show the preview balloons
    //mKeyboardView.setPreviewEnabled(false);

    // Install the key handler
    mKeyboardView.setOnKeyboardActionListener(mOnKeyboardActionListener);

**注意， mKeyboard 和 mKeyboardView 是，你必须创建私有类变量。

**Note that mKeyboard and mKeyboardView are private class variables that you have to create.

然后你需要下面的函数用于打开键盘（你必须通过的onClick XML属性的TextView它相关联）

Then you need the following function for opening the keyboard ( you must associate it with the TextView through the onClick xml property)

    public void openKeyboard(View v)
    {
       mKeyboardView.setVisibility(View.VISIBLE);
       mKeyboardView.setEnabled(true);
       if( v!=null)((InputMethodManager)getSystemService(Activity.INPUT_METHOD_SERVICE)).hideSoftInputFromWindow(v.getWindowToken(), 0);
    }

最后，你需要在 OnKeyboardActionListener 将要处理的事件

private OnKeyboardActionListener mOnKeyboardActionListener = new OnKeyboardActionListener() {
    @Override public void onKey(int primaryCode, int[] keyCodes) 
    {
         //Here check the primaryCode to see which key is pressed 
         //based on the android:codes property
         if(primaryCode==1)
         {
            Log.i("Key","You just pressed 1 button");
         }
    }

    @Override public void onPress(int arg0) {
    }

    @Override public void onRelease(int primaryCode) {
    }

    @Override public void onText(CharSequence text) {
    }

    @Override public void swipeDown() {
    }

    @Override public void swipeLeft() {
    }

    @Override public void swipeRight() {
    }

    @Override public void swipeUp() {
    }
};
