推荐答案

在任何不同势输入布局采用Android：keyBackground =...

On any diffrent input layout use android:keyBackground=".."

例如：

input.xml中：

input.xml:

<com.example.KeyboardView
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/keyboard"
        android:layout_alignParentBottom="true"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:keyBackground="@drawable/blue_key"
        />

input1.xml：

input1.xml:

<com.example.KeyboardView
            xmlns:android="http://schemas.android.com/apk/res/android"
            android:id="@+id/keyboard"
            android:layout_alignParentBottom="true"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:keyBackground="@drawable/red_key"
            />

然后OnCreateInputView方式：

then on OnCreateInputView method:

@Override public View onCreateInputView() {
    if(theme == 1)
        mInputView = (KeyboardView) getLayoutInflater().inflate(R.xml.input , null);
    else
        mInputView = (KeyboardView) getLayoutInflater().inflate(R.xml.input1 , null);
    mInputView.setOnKeyboardActionListener( this);
    mInputView.setKeyboard(mQwertyKeyboard);
    mComposing.setLength(0);
    return mInputView;
}

和在方法结束onStartInput添加此

and on the end of the method onStartInput add this:

setInputView(onCreateInputView());

如果您已经做了它，你需要的是设置一个不同的背景，特殊键。也许解决我的问题，我写将帮助您：<一href=\"http://stackoverflow.com/a/18354298/2683898\">http://stackoverflow.com/a/18354298/2683898

If you've already done it and what you need is to set a different background to special keys. Maybe the solution to my problem that I wrote will help you: http://stackoverflow.com/a/18354298/2683898
