BottomNavigationView show/hide 而不是 replace

https://stackoverflow.com/questions/54087740/how-to-hide-bottomnavigationview-on-android-navigation-lib

You could do something like this in your activity's onCreate. When ever an item in the nav bar is selected it will show or hide the nav based on the fragment id's.

private fun setupNav() {
    val navController = findNavController(R.id.nav_host_fragment)
    findViewById<BottomNavigationView>(R.id.bottomNav)
        .setupWithNavController(navController)

    navController.addOnDestinationChangedListener { _, destination, _ ->
        when (destination.id) {
            R.id.mainFragment -> showBottomNav()
            R.id.mineFragment -> showBottomNav()
            else -> hideBottomNav()
        }
    }
}

private fun showBottomNav() {
    bottomNav.visibility = View.VISIBLE
}

private fun hideBottomNav() {
    bottomNav.visibility = View.GONE
}

混淆

单例

companion object {
    private var usbUtils: UsbUtils? = null
    fun getInstance(): UsbUtils {
        if (usbUtils == null) {
            synchronized(UsbUtils::class.java) {
                if (usbUtils == null) {
                    usbUtils = UsbUtils()
                }
            }
        }
        return usbUtils!!
    }
}

DataBinding 在XML中的具体使用方式


<androidx.swiperefreshlayout.widget.SwipeRefreshLayout
    android:id="@+id/swipeRefresh"
    bind:colorSchemeResources="@{resId}"
    bind:onRefreshListener="@{() -> viewModel.onRefresh()}"
    bind:refreshing="@{viewModel.refreshing}"
    android:layout_width="match_parent"
    android:layout_height="match_parent"></androidx.swiperefreshlayout.widget.SwipeRefreshLayout>

<TextView
    android:id="@+id/tv_article_tabs"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text='@{"复杂的表达式显示结果  "+@string/app_name+" -> "  + viewModel.wxArticleTabs.size()}' />

<ImageView
    android:id="@+id/iv_article_tabs_bind"
    loadPic="@{viewModel.tempImageUrl}"
    android:layout_width="35dp"
    android:layout_height="35dp"
    android:layout_marginTop="3dp"
    android:scaleType="centerCrop" />

Tips

NavController,BottomNavigationView 不同步问题

https://medium.com/@freedom.chuks7/how-to-use-jet-pack-components-bottomnavigationview-with-navigation-ui-19fb120e3fb9

xml中 fragment -> FragmentContainerView 异常

https://stackoverflow.com/questions/58320487/using-fragmentcontainerview-with-navigation-component

error:
navController = Navigation.findNavController(this, R.id.nav_host)

success:
val navHostFragment = supportFragmentManager.findFragmentById(R.id.nav_host) as NavHostFragment
navController = navHostFragment.navController

Retrofit 姿势错误

 URL query string "{page}" must not have replace block. For dynamic query parameters use @Query.
     for method ApiService.getRecommendProjects

Glide AppGlideModule

Failed to find GeneratedAppGlideModule. You should include an annotationProcessor compile dependency on com.github.bumptech.glide:compiler in your application and a @GlideModule annotated AppGlideModule implementation or LibraryGlideModules will be silently ignored

LiveData() with no args

Failed to invoke public androidx.lifecycle.LiveData() with no args

6.BaseAdapter 用法

class CustomAdapter :
    BaseRecyclerAdapter<String>(R.layout.xxx, null) {
    override fun bindData(holder: BaseViewHolder, position: Int, item: String) {
    }
}

class CustomAdapter2 : BaseAdapter<String, CustomHolder>(null) {
    override fun getViewHolder(view: View): CustomHolder {
        return CustomHolder(view)
    }

    override fun bindData(holder: CustomHolder, position: Int, item: String) {
    }
}

class CustomHolder(v: View) : BaseViewHolder(v) {
}
