推荐答案

我假设您正在使用提供的android.support.v17.leanback.widget.RowHeaderPresenter作为BrowseFragment中HeaderFragment的演示者.

I am assuming you are using the provided android.support.v17.leanback.widget.RowHeaderPresenter as the presenter for the HeaderFragment in your BrowseFragment.

RowHeaderPresenter从R.layout.lb_row_header扩展布局，如下所示:

The RowHeaderPresenter inflates the layout from R.layout.lb_row_header which looks like this:

<android.support.v17.leanback.widget.RowHeaderView
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/row_header"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    style="?rowHeaderStyle" />

如您所见，它使用了名为rowHeaderStyle的样式属性，该属性通常指向@style/Widget.Leanback.Row.Header.您可以通过在styles.xml中放置以下内容来覆盖它:

As you can see, this uses a style attribute called rowHeaderStyle, which is normally pointing to @style/Widget.Leanback.Row.Header. You can override this by putting the following in your styles.xml:

<style name="MyCustomRowHeaderStyle" parent="Widget.Leanback.Row.Header">
    <item name="android:textColor">@color/red</item>
</style>

<style name="MyCustomBrowseStyle" parent="Theme.Leanback.Browse">
    <item name="rowHeaderStyle">@style/MyCustomRowHeaderStyle</item>
</style>

，然后在AndroidManifest.xml中声明MyCustomBrowseStyle，将MyCustomBrowseStyle用于包含BrowseFragment的Activity.

And then use MyCustomBrowseStyle for the Activity containing the BrowseFragment by declaring it in your AndroidManifest.xml.
