我想您正在从数据数组中获取文件扩展名示例.mp4/.mp3等或Audio/Video标志。
创建一个采用文件信息示例的函数:
navigateTo = (fileinfo) => {
// const filetype = check for file type, Audio/Video or file extension
if (filetype === 'Audio'){
this.props.navigation.navigate('Audio', {id: fileinfo.id})
} else {
this.props.navigation.navigate('Video', {id: fileinfo.id})
}
将此传递给您的TouchableOpacity:
<TouchableOpacity
onPress={() => navigateTo(item)}>
// your code here
</TouchableOpacity>

super(props)
this.state = {
ItemindexChecked: "",
}
this.Dataarrayholder = latestuploads;
}
............................your code ............
DataFilter(p_value)
{
const newData = this.Dataarrayholder.filter(function (item) {
const itemData = item.value ? item.value.toUpperCase() : ''.toUpperCase();
const textData = p_value.toUpperCase();
return itemData.indexOf(textData) > -1;
if (p_value != "")
{
if (newData == 0) {
return
}
else
{
this.props.navigation.navigate('Audio', { id: newData[0].id });
}
}
});
}
...........................................your code ..............
<FlatList

data={latestuploads}
keyExtractor={item => item.id}
renderItem={({ item }) => {
return (
<ScrollView horizontal={true}>
<Card transparent style={{ width: 170 }}>
<TouchableOpacity
//onPress={() =>
// // this.props.navigation.navigate('Audio', { id: item.id })
// }
onPress={() => { this.DataFilter(item.value), this.setState({ ItemindexChecked: item.key }) }}
