【问题描述】：
我创建了一个销售订单菜单，该菜单使用 Activity 和 Fragment 文件， 问题是当我显示客户列表页面以查找将在 SalesOrder 页面上使用的客户数据时（创建数据选项卡（使用片段）） CustomerList 页面未关闭， 这是我的代码 首播节目
然后我像这样点击销售订单显示，它的文件 SalesOrderActivity.kt Page SalesOrder 使用 TabLayout 和 Fragment ，即（用于创建数据和片段列表数据的片段） enter image description here
File SalesOrderActivity.kt
class SalesOrderActivity : AppCompatActivity() {
lateinit var viewPager : ViewPager
lateinit var tabs : TabLayout
private var appContext: Context? = null
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_sales_order)
CommonCtx.setViewXml2(contentView)
setSupportActionBar(findViewById(R.id.my_toolbar))
supportActionBar!!.title = "Sales Order"
supportActionBar!!.setDisplayHomeAsUpEnabled(true)
viewPager = findViewById(R.id.viewPager)
tabs = findViewById(R.id.tabs)
tabs.addOnTabSelectedListener(object : TabLayout.OnTabSelectedListener {
override fun onTabSelected(tab: TabLayout.Tab?) {
val position = tab?.position
if (position == 1) {
println("get selected")
}
}
override fun onTabUnselected(tab: TabLayout.Tab?) {
}
override fun onTabReselected(tab: TabLayout.Tab?) {
}
})
appContext = this
CommonCtx.setActivity(this)
setUpTabs()
}
//SHOW FRAGMENT CREATE DATA AND LIST DATA
private fun setUpTabs(){
val adapter = com.myapp.sfa.adapter.ViewPagerAdapter(supportFragmentManager)
adapter.addFragment(SalesOrderCreateDataFragment(), "Create Data")
adapter.addFragment(CustomerListDataFragment(), "List Data")
viewPager.adapter = adapter
tabs.setupWithViewPager(viewPager)
setupTabIcons()
}
private fun setupTabIcons() {
tabs.getTabAt(0)!!.setIcon(tabIcons.get(0))
tabs.getTabAt(1)!!.setIcon(tabIcons.get(1))
}
private val tabIcons = intArrayOf(
R.drawable.add_sign,
R.drawable.list_48
)
override fun onSupportNavigateUp(): Boolean {
finish()
return true
}
}
在页面销售订单中，我使用片段显示选项卡创建数据和列出数据 这 文件 SalesOderCreateDataFragment.kt
class SalesOrderCreateDataFragment : Fragment() {
private var appContext: Context? = null
private lateinit var txtvCustId : TextView
public lateinit var edtCustCode : EditText
private lateinit var btnCustomer : Button
lateinit var DBHelper : DBHelper
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
appContext = this.getActivity()
DBHelper = DBHelper(appContext!!))
}
override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?,
savedInstanceState: Bundle?): View? {
val view = inflater.inflate(R.layout.fragment_sales_order_create_data,container,false)
txtvCustId = view.findViewById<TextView>(R.id.txtvCustId)
edtCustCode = view.findViewById<EditText>(R.id.edtCustCode)
btnCustomer = view.findViewById(R.id.btnCustomer)
btnCustomer.setOnClickListener {
showCustomer()
}
appContext = this.getActivity()
return view
}
//SHOW LIST CUSTOMER event clik Cust. Code
fun showCustomer() {
val intent = Intent(this.getActivity(), CustomerListActivity::class.java)
//intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK or Intent.FLAG_ACTIVITY_CLEAR_TOP)
intent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK)
CommonCtx.getContext().startActivity(intent)
CustomerListActivity().finish()
}
fun getCustomer(idCustomer: String){
var customerPojo = CustomerPojo()
customerPojo= SQLCustomer().getCustomerById(idCustomer)
}
}
当我点击按钮 Cust Code enter image description here
会显示页面CustomerListActivity，像这张图 客户代码事件中的代码
File CustomerListActivity.kt
class CustomerListActivity : AppCompatActivity() {
private lateinit var recyclerView : RecyclerView
lateinit var DBHelper : DBHelper
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)

setSupportActionBar(findViewById(R.id.my_toolbar))
supportActionBar!!.title = "Customer List"
supportActionBar!!.setDisplayHomeAsUpEnabled(true)
recyclerView =findViewById(R.id.recyclerView)
DBHelper = DBHelper(applicationContext)//this)
//get data customer in database local
var listCustomerPojo : MutableList<CustomerPojo> = ArrayList()
listCustomerPojo = SQLCustomer().getCustomerList()
//show data customer in Recycle Card View
showListDataToRecycleCardView(listCustomerPojo);
}
override fun onCreateOptionsMenu(menu: Menu): Boolean {

return true
}
override fun onQueryTextChange(newText: String?): Boolean {
var listCustomerPojo: ArrayList<CustomerPojo> = ArrayList()
if (newText!!.isNotEmpty()) {
val search = newText.toLowerCase()
listCustomerPojo = SQLCustomer().getCustomerByName(newText)
}
showListDataToRecycleCardView(listCustomerPojo);
return true
}
})
}
return super.onCreateOptionsMenu(menu)
}
fun showListDataToRecycleCardView(listCustomerPojo: MutableList<CustomerPojo>){
var customerListDC = arrayListOf<CustomerDataModel>()
for (i in 0 until listCustomerPojo.size) {

custPojo.custId.toString(),

customerListDC.add(cdm)
}
val recyclerAdapter = CustomerListRecyclerAdapter(customerListDC)
recyclerView.apply {
adapter = recyclerAdapter

}
}
