java - Android TV Fragment(主 fragment )以垂直方向出现？

Question

运行代码后，我的屏幕变成垂直方向，为什么？

这是我的主要 fragment (XML)----

我希望所有内容都以横向模式显示，因为它通常显示在电视上..

<?xml version="1.0" encoding="utf-8"?>
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/main_browse_fragment"
    android:name="com.amriksingpadam.my_androidtv.MainFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity"
    tools:deviceIds="tv"
    tools:ignore="MergeRootFrame" />

我找不到答案，请帮忙？

主要 fragment (Java)--

public class MainFragment extends BrowseFragment {
    private static final String TAG = MainFragment.class.getSimpleName();

    public void onActivityCreated(Bundle savedInstanceState){
        Log.i(TAG,"On Activity Created!!");
        super.onActivityCreated(savedInstanceState);
        setupUIElements();
    }

    public void setupUIElements(){
        setTitle("BOB TV");
    }

}
