我正在尝试为可拖动的平面列表编写一个简单的代码。对于 FlatList,相同的代码运行得非常好。在下面的代码中,如果我将 FlatList 替换为 DraggableFlatList,尽管从渲染组件“TaskListTile”显示日志,但屏幕上没有任何内容
this.state = {
data: [{key: '0',id:'0', name: 'Tasklist1', totalTasks: '10', completedTasks: '9'},
{key: '1',id:'1', name: 'Tasklist2', totalTasks: '12', completedTasks: '9'},
{key: '2',id:'2', name: 'Tasklist3', totalTasks: '50', completedTasks: '1'}
]
}
}
render(){
return (
<FlatList
data={this.state.data}
renderItem= {({item}) =><TaskListTile displayData={item}/>}
keyExtractor={item => item.id}
scrollPercent={5}
onMoveEnd={({ data }) => this.setState({ data })}
/>
)
};
TaskListTile.js
const {id, name, completedTasks, totalTasks} = this.props.displayData;
return (
<View key={id} style={{backgroundColor:'#d6eef8', borderColor:'#00CCFF', borderWidth:1,margin:10,padding:10, borderRadius:5}}>
<Text style={{color:'#00CCFF', fontSize:20}}>{name}</Text>
<View style={{flexDirection:'row'}}>
<Text>Tasks completed: {completedTasks}/{totalTasks}</Text>
<View style={{flex:1, alignItems:'flex-end'}}>
<ProgressBar progress={parseInt( this.props.displayData.completedTasks)/parseInt( this.props.displayData.totalTasks)} style={{height:8, width:90}}/>
</View>
</View>
</View>
);
}
