Kotlin写法学习
mMainBottomBar.setBackgroundStyle(BottomNavigationBar.BACKGROUND_STYLE_STATIC)
mMainBottomBar.setMode(BottomNavigationBar.MODE_FIXED)
mMainBottomBar.addItem(BottomNavigationItem(R.mipmap.ic_launcher, R.string.main_home_tab)).setActiveColor(R.color.colorPrimaryDark).setInActiveColor(R.color.colorMain)
.addItem(BottomNavigationItem(R.mipmap.ic_launcher, R.string.main_loan_tab)).setActiveColor(R.color.colorPrimaryDark).setInActiveColor(R.color.colorMain)
.addItem(BottomNavigationItem(R.mipmap.ic_launcher, R.string.main_user_tab)).setActiveColor(R.color.colorPrimaryDark).setInActiveColor(R.color.colorMain)
.setFirstSelectedPosition(0)
.initialise()
mMainBottomBar.setTabSelectedListener(this)
onTabSelected(0)
设置导航栏模式：
setBackgroundStyle、setMode具体细节参考博客Feathers . 文藝学生
override fun onTabSelected(position: Int) {
supportFragmentManager.beginTransaction().apply {
when (position) {
0 -> {
homeFragment = HomeFragment.newInstance("", "")
replace(R.id.mMainFl, homeFragment)
}
1 -> {
loanFragment = LoanFragment.newInstance("", "")
replace(R.id.mMainFl, loanFragment)
}
2 -> {
userCenterFragment = UserCenterFragment.newInstance("", "")
replace(R.id.mMainFl, userCenterFragment)
}
}
}.commitAllowingStateLoss()
