为 Fragment 设置主题 [英] Set theme for a Fragment

问题描述

我正在尝试为片段设置主题.

I'm trying to set the theme for a fragment.

在清单中设置主题不起作用:

Setting the theme in the manifest does not work:

android:theme="@android:style/Theme.Holo.Light"

查看以前的博客，似乎我必须使用 ContextThemeWrapper.任何人都可以向我推荐一个编码示例吗?我找不到任何东西.

From looking at previous blogs, it appears as though I have to use a ContextThemeWrapper. Can anyone refer me to a coded example? I can't find anything.

推荐答案

在 manifest 中设置 Theme 通常用于 Activity.

Setting Theme in manifest is usually used for Activity.

如果要为 Fragment 设置 Theme，请在 Fragment 的 onCreateView() 中添加以下代码:

If you want to set Theme for Fragment, add next code in the onCreateView() of the Fragment:

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

    // create ContextThemeWrapper from the original Activity Context with the custom theme
    final Context contextThemeWrapper = new ContextThemeWrapper(getActivity(), R.style.yourCustomTheme);

    // clone the inflater using the ContextThemeWrapper
    LayoutInflater localInflater = inflater.cloneInContext(contextThemeWrapper);

    // inflate the layout using the cloned inflater, not default inflater
    return localInflater.inflate(R.layout.yourLayout, container, false);
}
