我正在尝试创建一个DialogFragment,当用户在字段中输入文本时,会动态地将EditTexts添加到RecyclerView。我遇到的问题应该很容易。
我有两个我想要的初始EditText框,一个有焦点,一个无法获得焦点。但是,键盘永远不会出现。我可以点击EditText来粘贴文本,但我所做的一切都不能让键盘显示出来。
我正在使用一个自定义的ArrayViewAdapter,它扩展了RecyclerView.Adapter,将EditText字段放在它自己的线性布局中。
以下是相关代码:
layout_linear.xml - > RecyclerView项目的布局文件
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/ll"
android:orientation="vertical"
android:layout_weight="1">
</LinearLayout>
ArrayViewAdapter:
class ArrayViewAdapter<E>(val data: ArrayList<E>, c: Context) :
RecyclerView.Adapter<ArrayViewAdapter.ViewHolder>() where E : View {
...
override fun onCreateViewHolder(parent: ViewGroup?, viewType: Int): ViewHolder {
val view = LayoutInflater.from(parent?.context)
.inflate(R.layout.layout_linear, parent, false)
return ViewHolder(view)
}
...
class ViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView) {
// The ID of the TableLayout
val ll = itemView.findViewById<LinearLayout>(R.id.ll)
fun bind(v : View) {
ll.addView(v)
ll.clearFocus()
}
}
ListEntryDialog:
override fun onCreateDialog(savedInstanceState: Bundle?): Dialog {
val view = activity.layoutInflater.inflate(R.layout.fragment_list_entry_dialog, null)
...
val ed1 = EditText(activity)
//ed1.addTextChangedListener(dw)
ed1.layoutParams = LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,
LinearLayout.LayoutParams.WRAP_CONTENT)
ed1.requestFocus()
val ed2 = EditText(activity)
//ed2.addTextChangedListener(dw)
ed2.layoutParams = LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,
LinearLayout.LayoutParams.WRAP_CONTENT)
ed2.isFocusableInTouchMode = false
ed2.isFocusable = false
fields.add(ed1)
fields.add(ed2)
adapter = ArrayViewAdapter(fields, activity)
rv.adapter = adapter
...
val builder = AlertDialog.Builder()
return builder.create()
对话框的xml文件:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:orientation="vertical"
android:name="com.github.jlcarveth.grocer.layout.fragment.ListEntryDialog"
tools:context="com.github.jlcarveth.grocer.layout.fragment.ListEntryDialog">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/led_title"
android:text="TITLE"/>
<android.support.v7.widget.RecyclerView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/led_rv"
app:layoutManager="LinearLayoutManager">
</android.support.v7.widget.RecyclerView>
</LinearLayout>
键盘为什么不显示?
