我的按钮没有在我的容器中散开 [英] My button isn't spreading across my container

问题描述

我正在尝试以这种方式设置按钮样式，该样式将散布在我的视图中.目前，它在我的按钮的左侧和底部创建了白色边框(请参见随附的屏幕截图).

I am trying to set my button style that way, it will be spread across my View. Currently its creating white border on the left and on the bottom of my button (see attached screenshot).

我的代码:

let {width, height} = Dimensions.get('window');
        let photoWidth = width/4;

return (
            <View style={{width: width, height: 500}}>
                <ScrollView style={{width: width, height: height}}>
                    <View style={{flexDirection: 'row', width: width, flexWrap: 'wrap'}}>
                    {
                        this.state.photos.map((p, i) => {
                            return (
                                <SelectedPhoto
                                    key={i}
                                    index={i}
                                    style={{
                                        width: photoWidth,
                                        height: photoWidth,
                                    }}
                                    limit={this.state.supportLength}
                                    photo={p}
                                    onSelectPhoto={this.onSelectPhoto}
                                    onDeselectPhoto={this.onDeselectPhoto}
                                />
                            );
                        })
                    }
                    </View>
                </ScrollView>
                <View style={{ flexDirection:"row", flexWrap: 'wrap', width: width }}>
                    <Button

                        onPress={this.onNext}  
                        containerViewStyle={{width: width}}
                        backgroundColor={Colors.red}
                        title='NEXT' />
                </View>             
            </View>
        );

推荐答案

我考虑了react-native中使用的Button组件.只需删除在设置width时添加的wrapper flex.

I consider Button component you used from react-native. Just remove wrapper flex you added as you set width to it.

<Button
   onPress={this.onNext}  
   containerViewStyle={{width: width}}
   backgroundColor={Colors.red}
   title='NEXT' />
