如何解决如何在列表视图中隐藏键盘？
当我在列表视图中的 editText 中输入数字时，仍然显示一个 qwerty 键盘。
请查看此动画 GIF https://ibb.co/4K9dz1N 以了解问题所在。 （请点击“lire le GIF”启动动画GIF）
我已经实现了我在 stackoverflow 中找到的两个函数（一个带有 hidekeyboard 函数的 setOnItemClickListener）但是没有结果......
这是我的应用程序的代码。
主要活动：
import android.app.Activity
import android.content.Context
import android.os.Bundle
import android.view.inputmethod.InputMethodManager
import android.widget.AdapterView.OnItemClickListener
import android.widget.EditText
import android.widget.ListView
import android.widget.TextView
import androidx.appcompat.app.AppCompatActivity
class MainActivity : AppCompatActivity() {
lateinit var textView2: TextView
lateinit var listView: ListView
//var adapter: MyAdapter? = null
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
title = "KotlinApp"
listView = findViewById(R.id.listView)
textView2 = findViewById(R.id.textView2)
listView.adapter=CustomAdapter(DataClass(),this)
var textView2: TextView
textView2 = findViewById(R.id.textView2)
var editText : EditText
listView.setOnItemClickListener({ parent,view,position,id -> hideKeyboard(this) })
}
fun hideKeyboard(context: Context) {
try {
val inputManager: InputMethodManager =
context.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
val view = (context as Activity).currentFocus
if (view != null) {
inputManager.hideSoftInputFromWindow(
view.windowToken,InputMethodManager.HIDE_NOT_ALWAYS
)
}
} catch (e: Exception) {
e.printStackTrace()
}
}
fun Update()
{
}
fun fonction ()
{
var textView2: TextView
}
fun fonction2 ()
{
var textView2: TextView
// textView2 = findViewById(R.id.textView)
//textView2.text="?????"
}
private fun generateData(): List<String> {
val data: MutableList<String> = ArrayList()
for (i in 0..99) {
data.add(i.toString() + "th Element")
}
return data
}
}
class DataClass(){
var list1: MutableList<String> = generateData2() as MutableList<String>
var list2: MutableList<String> = generateData3() as MutableList<String>
var list3: MutableList<String> = generateData4() as MutableList<String>
private fun generateData2(): List<String> {
val data: MutableList<String> = mutableListOf()
for (i in 0..99) {
data.add(i.toString())
}
return data
}
private fun generateData3(): List<String> {
val data: MutableList<String> =mutableListOf()
for (i in 0..99) {
data.add("")
}
return data
}
private fun generateData4(): List<String> {
val data: MutableList<String> = mutableListOf()
for (i in 0..99) {
data.add("")
}
return data
}
}

感谢您的帮助
解决方法
将以下代码添加到您的 RecyclerView 或 ListView 的父视图中
android:descendantFocusability="blocksDescendants"
android:focusable="false"
android:focusableInTouchMode="false"
将此 android:imeOptions="actionDone" 添加到您的 edittext xml 中。这将隐藏完成按钮上的键盘。
