這是我的代碼Iam使用 API 并從中獲取資料...如果iam控制臺表示它可以正常作業，但does'nt在使用時會顯示它FlatList
Text,FlatList,Button,TouchableOpacity從'react-native'匯入{視圖， }；從“反應”匯入反應，{ useState,useEffect}；
const LyricsGet = () => {
const url = "https://api.lyrics.ovh/v1/Sia/unstoppable";
const[lyric,setLyric]=useState([]);
Fetching the data using useEffect
useEffect(() => {
console.log("inside the useeffect");
fetch(url)
.then(response => response.json())
.then(results => {
console.log(results);
setLyric(results);
})
.catch(err => {
setError(err);
});
console.log("inside the useeffect 22222");
}, []);
return (
<View>
<FlatList
data={lyric}
renderItem={({ item }) => <Text key={item._id}>{item.lyrics}</Text>}
keyExtractor={item => item.id}
/>
</View>
);
}

您的結果變數是一個物件。
您可以通過在設定歌詞時創建一個陣列來實作您想要的：
setLyric([results]);

您從 useState lyric.. 獲得的資料是一個物件，對嗎？FlatList 需要一個陣列。
