需求：React Native FlatList在每次添加item时候滚动到底部
... onContentSizeChange = (contentWidth, contentHeight) => { const newLength = this.state.data.length; newLength > this._lastDataLength && requestAnimationFrame(() => this._flatListRef && this._flatListRef.scrollToEnd({ animated: true })); this._lastDataLength = newLength; }; refHandler = ref => { this._scrollViewRef = ref; //如果你用的是 AnimatedFlatList，这里应该这样写 //this._scrollViewRef = ref && ref.getNode(); }; render() { const {data} = this.state; return ( <FlatList data={data} ref={this.refHandler} keyExtractor={this.keyExtractor} renderItem={this.renderItem} onContentSizeChange={this.onContentSizeChange} /> ); } ...
