Question

我正在构建一个应用程序，根据用户的当前位置抓取用户的地址。我希望用户能够像textView（移动Marqueee）格式一样看到它。请帮忙缩短它：我需要的是一个文本视图，它可以显示用户的实时位置以及用户在特定位置的时间。它应以textview格式显示地址和时间..请同时包含位置代码。

以下是我的XML

import kotlinx.android.synthetic.main.fragment_fragment_first.*
import kotlinx.android.synthetic.main.fragment_fragment_second.*
import kotlinx.android.synthetic.main.fragment_fragment_third.*
    ...
    override fun onNavigationItemSelected(item: MenuItem): Boolean {
    // Handle navigation view item clicks here.
    objPageAdapter = CustomPageAdapter(supportFragmentManager)
    when (item.itemId) {
        R.id.nav_fruits -> {
            objPageAdapter!!.removeFragments()
            objPageAdapter!!.addFragments(FragmentFirst(),getString(R.string.txt_tab_fruits_Element_1))
            objPageAdapter!!.addFragments(FragmentSecond(),getString(R.string.txt_tab_fruits_Element_2))
            objPageAdapter!!.addFragments(FragmentThird(),getString(R.string.txt_tab_fruits_Element_3))
            ViewPagerMain.adapter = objPageAdapter
            TabLayoutMain.setupWithViewPager(ViewPagerMain)
            this.textViewFragment_1.text = getString(R.string.txt_txtView_fruits_Element_1)
            this.textViewFragment_2.text = getString(R.string.txt_txtView_fruits_Element_2)
            this.textViewFragment_3.text = getString(R.string.txt_txtView_fruits_Element_3)
            ...

使用位置坐标获取地址。即纬度和经度，Android Locations提供查找API，你可以在这里找到官方文件https://developer.android.com/training/location/display-address.html
