专业网站设计网站,株洲网站优化哪家强,如何不花钱做网站,小网站做几个关键词间隙设置为零
因为当我们引入TabLayout时就已经默认tabPaddingStart为12dp,tabPaddingEnd为12dp.才会导致不能填满的原因#xff0c;这时我们只需要修改样式或者属性即可。 xmlns:apphttp://schemas.android.com/apk/res-auto app:tabPaddingStart0dp这时我们只需要修改样式或者属性即可。 xmlns:apphttp://schemas.android.com/apk/res-auto app:tabPaddingStart0dp
app:tabPaddingEnd0dp
