Landing Screen Navigation

Open Beta Documentation Amazon offers this technical documentation as part of a pre-release, open beta. The features described might change as Amazon receives feedback and iterates on the features. For the most current feature information, see the Release Notes.

Let's add navigation to LandingScreen, so that we can load the VideoDetailsScreen when we click on a VideoCard.

In LandingScreen.tsx destructure navigation in the parameters for LandingScreen, declaring it to be of type any.

const LandingScreen = ({ navigation }: any) => {
  // LandingScreen code
}

Update the VideoCard to take in the new prop pressFunction and set it to navigate to the VideoDetailScreen
Add { video: item } as a parameter to the navigate call.

    <VideoCard
        key={item.id}
        title={item.title}
        description={item.description}
        imgURL={item.imgURL}
        pressFunction={() => navigation.navigate("VideoDetailScreen", { video: item })}
    />

The LandingScreen.tsx code should look like this:

Copied to clipboard.

import React, {useState, useEffect} from 'react';
import {FlatList, StyleSheet, View, Text} from 'react-native';
import {Header, VideoCard} from '../components';
import {TVFocusGuideView} from '@amazon-devices/react-native-kepler';

interface IVideo {
  id: string;
  title: string;
  description: string;
  duration: number;
  thumbURL: string;
  imgURL: string;
  videoURL: string;
  categories: Array<string>;
  channel_id: number;
}

const LandingScreen = ({navigation}: any) => {
  const [islandVideos, setIslandVideos] = useState<IVideo[]>([]);
  const [underwaterVideos, setUnderwaterVideos] = useState<IVideo[]>([]);

  const url = 'https://d2ob7xfxpe6plv.cloudfront.net/TestData.json';

  const getAllVideos = () => {
    fetch(url)
      .then((response) => response.json())
      .then((data) => {
        // Filter videos for each category
        const islands = data.testData.filter(
          (video: IVideo) =>
            video.categories && video.categories.includes('Costa Rica Islands'),
        );

        const underwater = data.testData.filter(
          (video: IVideo) =>
            video.categories &&
            video.categories.includes('Costa Rica Underwater'),
        );

        setIslandVideos(islands);
        setUnderwaterVideos(underwater);
      })
      .catch((error) => {
        console.log(error);
      });
  };

  useEffect(() => {
    getAllVideos();
  }, []);

  return (
    <>
      <Header />
      <TVFocusGuideView autoFocus={true}>
        <Text style={styles.categoryTitle}>Costa Rica Islands</Text>
        <FlatList
          style={styles.flatList}
          horizontal
          data={islandVideos}
          renderItem={({item}) => (
            <View style={styles.itemContainer}>
              <VideoCard
                title={item.title}
                description={
                  item.description.split(' ').slice(0, 20).join(' ') + '...'
                }
                imgURL={item.imgURL}
                pressFunction={() =>
                  navigation.navigate('VideoDetailScreen', {video: item})
                }
              />
            </View>
          )}
        />
      </TVFocusGuideView>
      <TVFocusGuideView autoFocus={true}>
        <Text style={styles.categoryTitle}>Costa Rica Underwater</Text>
        <FlatList
          style={styles.flatList}
          horizontal
          data={underwaterVideos}
          renderItem={({item}) => (
            <View style={styles.itemContainer}>
              <VideoCard
                title={item.title}
                description={
                  item.description.split(' ').slice(0, 20).join(' ') + '...'
                }
                imgURL={item.imgURL}
                pressFunction={() =>
                  navigation.navigate('VideoDetailScreen', {video: item})
                }
              />
            </View>
          )}
        />
      </TVFocusGuideView>
    </>
  );
};

const styles = StyleSheet.create({
  flatList: {
    padding: 10,
  },
  itemContainer: {
    margin: 10,
  },
  categoryTitle: {
    fontSize: 24,
    fontWeight: 'bold',
    color: 'white',
    marginLeft: 30,
  },
});

export default LandingScreen;

Now if you click on a video it should take you to the VideoDetail Screen we created, however as you can see the Video Details are currently hardcoded so next we will update this screen to render the actual video data.
