首先，您将需要一个keyboard.xml文件，该文件将放置在res/xml文件夹中(如果该文件夹不存在，则创建该文件).

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:keyIcon="@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>

**请注意，您必须创建backspace drawable并将其放置在尺寸非常小(例如18x18像素)的res/drawable-ldpi文件夹中

**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)

然后在要使用它的XML文件(您的TextView所在的位置)中，应添加以下代码:

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>

**请注意，您将要放置android.inputmethodservice.KeyboardView的xml文件必须为RelativeLayout才能设置alignParentBottom="true"(通常，键盘位于屏幕底部)

**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，您需要在Activity的onCreate函数中添加以下代码，该函数处理要将键盘连接到的TextView.

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.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);

**请注意，mKeyboard和mKeyboardView是您必须创建的私有类变量.

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

然后，您需要以下功能来打开键盘(必须通过onClick xml属性将其与TextView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，您需要用于处理事件的OnKeyboardActionListener

And finally you need the OnKeyboardActionListener that will handle your events

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() {
    }
};
