rn 点击按钮 屏幕滑动到底部

<ScrollView style={{flex:1}}

//showsVerticalScrollIndicator={false}

// ref={(r) => this.scrollview = r}

ref={c => this._scrollview = c}

scrollsToEnd={true}

>

 

 

addRemarks = () => {

// this._scrollview.scrollTo({x:0,y:windowHeight*2,animated:true})

const editIndex = this.remarksArr.length;

this.setState({

editFlag: false,

editIndex,

addFlag: true,

 

})

setTimeout(()=> {

this._scrollview.scrollToEnd({animated:true,duration:500});

},500)

}

 

必须要加个延迟，不然方法无法执行
