我正在为设备创建自己的 IME。我需要添加的是键盘视图上方的文本框，如下图所示。虽然我可以如下图所示显示它，但我无法在其中写入文本。

在此处输入图像描述

我正在扩展键盘视图，下面是布局结构

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/wrapper"
    android:layout_height="wrap_content" android:orientation="vertical" 
    android:layout_width="fill_parent" android:background="@color/background" > 

   <TextView android:textAppearance="?android:attr/textAppearanceMedium" android:layout_height="wrap_content" android:id="@+id/txtTest" android:layout_width="fill_parent" android:text="Test" ></TextView>
       <EditText android:inputType="text" android:id="@+id/edtTest" android:layout_height="wrap_content" android:layout_width="fill_parent"></EditText>

<com.keyboard.CustomKeyboardView
            xmlns:android="http://schemas.android.com/apk/res/android"
            android:id="@+id/keyboard"
            android:layout_alignParentBottom="true"
            android:layout_width="fill_parent" android:layout_height="wrap_content"
            android:keyTextSize="15sp"
       />
  </LinearLayout>

公共类 CustomKeyboardView 扩展 KeyboardView {

static final int KEYCODE_OPTIONS = -100;

private TextView mResultText;
public CustomKeyboardView (Context context, AttributeSet attrs) {
    super(context, attrs);
    }

public CustomKeyboardView(Context context, AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);
}

@Override
protected boolean onLongPress(Key key) {
    if (key.codes[0] == Keyboard.KEYCODE_CANCEL) {
        getOnKeyboardActionListener().onKey(KEYCODE_OPTIONS, null);
        return true;
    } else {
        return super.onLongPress(key);
    }
}

谢谢， 无

您可以捕获您的软键盘事件并通过实现将它们传输到您自己的小部件KeyboardView.OnKeyboardActionListener。

在您的Inputmethodservice.onKey()方法中，您应该尝试将事件传输到 InputView 子视图，如下所示：

public class mySoftKeyboard 
    extends InputMethodService 
    implements KeyboardView.OnKeyboardActionListener {

// Implementation of KeyboardViewListener inside your InputMethodService
public void onKey(int primaryCode, int[] keyCodes) {
        //assuming your inputview is in private variable mInputView 
        //and contains public members txtTst and edtTst views 
        //(arrange for this in your InputView.onCreate)
        //Here, we just transmit the onKey code to View.onKeyDown/Up and let views draw themselves
        sendKey( mInputView.txtTst , primaryCode ); // send this to your TextView
        sendKey( mInputView.edtTst , primaryCode ); // also send to your EditText
    }

/**
 * Helper to send a character to the editor as raw key events.
 */
private void sendKey(View v, int keyCode) {
          v.onKeyDown(keyCode,new KeyEvent(KeyEvent.ACTION_DOWN, keyCode));
          v.onKeyUp  (keyCode,new KeyEvent(KeyEvent.ACTION_UP, keyCode));
}
    //other interface function, no need to implement
public void onText(CharSequence text){}
public void swipeRight() {}
public void swipeLeft() {}
public void swipeDown() {}
public void swipeUp() {}
public void onPress(int primaryCode) {}
public void onRelease(int primaryCode) {}
}

要回答您关于字形和键码之间区别的评论，这里有一个可以帮助您的代码片段：

//This snippet tries to translate the glyph 'primaryCode' into key events

//retrieve the keycharacter map from a keyEvent (build yourself a default event if needed)
KeyCharacterMap myMap=KeyCharacterMap.load(event.getDeviceId()); 

//event list to reproduce glyph
KeyEvent evs[]=null;

//put the primariCode into an array
char chars[]=new char[1];
chars[0]=primaryCode;

// retrieve the key events that could have produced this glyph
evs=myMap.getEvents(chars);

if (evs != null){
    // we can reproduce this glyph with this key event array
    for (int i=0; i< evs.length;i++) mySendKeyMethodHelper(evs[i]);
}
else { /* could not find a way to reproduce this glyph */ }
