@neilzhengzx 现在你可以通过

<PagerTitleIndicator
                style={styles.indicatorContainer}
                trackScroll={true}
                itemTextStyle={styles.indicatorText}
                itemStyle={{width:windowWidth/4}}
                selectedItemStyle={{width:windowWidth/4}}
                selectedItemTextStyle={styles.indicatorSelectedText}
                selectedBorderStyle={styles.selectedBorderStyle}
                titles={['SQUARE', 'CIRCLE','TRIANGLE','SQUARE', 'CIRCLE','TRIANGLE','SQUARE', 'CIRCLE','TRIANGLE']}
            />

指定itemStyle和selectedItemStyle的方式，来控制tabItem的宽，来达到你想要的撑满界面的效果了
