如何设置键盘背景的Andr​​oid [英] How to set keyboard background in Android

问题描述

这听起来很蠢，但我是认真的新手，在Android的编程。 我已经看过这个在互联网上，但它看起来像没有人这个曾经有过的困难。 我想提出一个软键盘为我们学校的Andr​​oid项目。 我打算让我自己的背景，这个键盘，但我无法弄清楚如何改变键盘的背景。 我在绘制DIR做出了buttonbgselector.xml文件：

This might sound stupid, but I'm seriously a newbie at Android programming. I have looked this up on the Internet, but it looks like nobody ever had difficulties with this. I am making a soft keyboard for our school Android project. I intended to make my own background for this keyboard, but I couldn't figure out how to change the keyboard's background. I made a buttonbgselector.xml file in my drawable dir:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:drawable="@drawable/button" />
<item
android:state_pressed="true"
android:drawable="@drawable/buttonpressed" />
<item
android:state_checkable="true"
android:drawable="@drawable/button" />
<item
android:state_checkable="true"
android:state_pressed="true"
android:drawable="@drawable/buttonpressed" />
<item
android:state_checkable="true"
android:state_checked="true"
android:drawable="@drawable/button" />
<item
android:state_checkable="true"
android:state_checked="true"
android:state_pressed="true"
android:drawable="@drawable/buttonpressed" />
</selector>

我试图在这里设置背景：

I tried setting the background here:

@Override public View onCreateInputView() {
    mInputView = (KeyboardView) getLayoutInflater().inflate(
            R.layout.input, null);
    mInputView.setBackgroundResource(R.drawable.buttonbgselector);
    mInputView.setOnKeyboardActionListener(this);
    mInputView.setKeyboard(mQwertyKeyboard);
    return mInputView;
}

和按键都还是一样的，没有什么改变。

And the keys are still the same, nothing changed.

推荐答案

有一个XML属性名为<一个href="http://developer.android.com/reference/android/inputmethodservice/KeyboardView.html#attr_android%3akeyBackground">keyBackground. 只需将该属性设置为一个绘制，它应该是好的。

There is a XML-Attribute called keyBackground. Just set this attribute to a drawable and it should be fine.

将此attrbute到KeyboardView中的 input.xml中的：

Add this attrbute to the KeyboardView in input.xml:

<KeyboardView android:keyBackground="@drawable/buttonbgselector" .../>
