布局

  <ViewStub
        android:id="@+id/place_holder"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_marginTop="56dp"
        android:layout="@layout/empty_placeholder" />

    android:background="@color/mdtp_white"
    android:clickable="true"
    android:focusable="true" //解決viewStub覆蓋的布局可以點擊的bug
    android:gravity="center">

    <ImageView
        android:id="@+id/ic"

    <TextView

</RelativeLayout>

kotlin中使用

    override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View? {
        ......
        placeHolder = view.findViewById(R.id.place_holder)
        ......
    }

   private fun showEmptyView() {
   placeHolder.visibility = View.VISIBLE//設置visibility ，內(nèi)部會在沒有inflate()執(zhí)行inflate()的
            view?.findViewById<TextView>(R.id.msg)?.text = String.format(getString(R.string.empty_msg), getString(R.string.deal))

    }

    private fun hideEmptyView() {
        placeHolder.visibility = View.GONE
    }
