问题描述

我想改变基于所述虚拟键盘是否被显示或不显示的布局。我搜索的API和各种博客，但似乎无法找到任何有用的东西。

I would like to alter the layout based on whether the virtual keyboard is shown or not. I've searched the API and various blogs but can't seem to find anything useful.

推荐答案

您已经得到了处理配置改变自己。

You've got to handle configuration changes yourself.

<一个href="http://developer.android.com/guide/topics/resources/runtime-changes.html#HandlingTheChange">http://developer.android.com/guide/topics/resources/runtime-changes.html#HandlingTheChange

示例：

// from the link above
@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);


    // Checks whether a hardware keyboard is available
    if (newConfig.hardKeyboardHidden == Configuration.HARDKEYBOARDHIDDEN_NO) {
        Toast.makeText(this, "keyboard visible", Toast.LENGTH_SHORT).show();
    } else if (newConfig.hardKeyboardHidden == Configuration.HARDKEYBOARDHIDDEN_YES) {
        Toast.makeText(this, "keyboard hidden", Toast.LENGTH_SHORT).show();
    }
}

然后，只需改变一些看法知名度，更新领域，改变你的布局文件。

Then just change the visibility of some views, update a field, and change your layout file.

这个解决方案将无法为软键盘工作， onConfigurationChanged 将不会被要求软键盘。

This solution will not work for soft keyboards and onConfigurationChanged will not be called for soft keyboards.
