Я создал представление переработчика в своем телевизионном приложении android, но оно ничего не показывает, я сделал это, как и для мобильных приложений, проверил отладку с использованием точек останова, и там отображаются данные представления обработчика.

Мой код выглядит следующим образом 

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/main_browse_fragment"

    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".activity.MainActivity"
    tools:deviceIds="tv"
    tools:ignore="MergeRootFrame"
    android:background="@drawable/home_bg"
    android:orientation="vertical">
    <RelativeLayout
        android:id="@+id/relTopLeft"

        android:layout_marginLeft="50dp">

        <ImageView
            android:layout_width="230dp"
            android:layout_height="120dp"
            android:scaleType="fitXY"
            android:src="@drawable/home_logo"></ImageView>


        <TextView

Что еще нужно сделать, чтобы отобразить его на телевизоре?

Ваш код выглядит нормально, но проверьте следующие вещи, которые могут вызвать проблемы

1. Попробуйте добавить эту строку и проверьте. 

rvSelector.setHasFixedSize(true);

2. также ради попытки удалите true из следующей строки и передайте false и LinearLayoutManager.HORIZONTAL здесь RecylerView.HORIZONTAL

вместо rvSelector.setLayoutManager(new LinearLayoutManager(this, LinearLayoutManager.HORIZONTAL,true));

измените его на

rvSelector.setLayoutManager(new LinearLayoutManager(this,RecyclerView.HORIZONTAL, false));

Я не знаю, почему вы используете это rvSelector.setNestedScrollingEnabled(false), попробуйте удалить его и проверить.
