Question

我的项目中有几种重要的自动完成功能。这是xml

<com.google.android.material.textfield.TextInputLayout
                            style="@style/AppTheme.TextInputLayout.AutoComplete"
                            android:layout_width="match_parent"
                            android:layout_height="wrap_content">

                            <AutoCompleteTextView
                                android:id="@+id/mPaisVeiculo"
                                style="@style/AppTheme.TextInputEditText.AutoComplete"
                                android:layout_width="match_parent"
                                android:layout_height="wrap_content"
                                android:hint="@string/pais" />

                        </com.google.android.material.textfield.TextInputLayout

这是样式

    <style name="AppTheme.TextInputLayout.AutoComplete" parent="Widget.MaterialComponents.TextInputLayout.FilledBox.ExposedDropdownMenu">
        <item name="android:background">@drawable/info_display_shape</item>
        <item name="hintTextAppearance">@style/AppTheme.TextFloatLabelAppearance</item>
        <item name="android:textColorHint">@color/textColorPrimary</item>
    </style>

    <style name="AppTheme.TextInputLayout.AutoComplete.TextFloatLabelAppearance" parent="TextAppearance.Design.Hint">
        <item name="android:textColor">@color/textColorPrimary</item>
        <item name="android:textSize">14sp</item>
    </style>

    <style name="AppTheme.TextInputEditText.AutoComplete" parent="Widget.AppCompat.AutoCompleteTextView">
        <item name="android:textSize">16sp</item>
        <item name="android:inputType">text</item>
        <item name="android:textColor">@color/textColorPrimary</item>
        <item name="backgroundTint">@color/white</item>
    </style>

这是适配器代码


import android.content.Context
import android.view.LayoutInflater
import android.view.View
import android.view.ViewGroup
import android.widget.ArrayAdapter
import android.widget.Filter
import com.google.android.material.textview.MaterialTextView
import com.google.gson.Gson
import com.google.gson.reflect.TypeToken
import java.util.*
import kotlin.collections.ArrayList

class TrocoRuaACAdapter(context: Context, listaTrocos: MutableList<ModTrocoRua>) :
    ArrayAdapter<ModTrocoRua>(context, 0, listaTrocos) {

    private val fullLista: List<ModTrocoRua> = ArrayList(listaTrocos)

    override fun getFilter(): Filter {
        return filtroTarifa
    }

    override fun getView(position: Int, convertView: View?, parent: ViewGroup): View {

        if(convertView == null){
            return LayoutInflater.from(context).inflate(R.layout.layout_autocomplete_generico, parent, false)
        }

        val txtViewNome: MaterialTextView = convertView.findViewById(R.id.mGenericLayouTextView)
        val itemTrocoRua:ModTrocoRua? = getItem(position)

        if(itemTrocoRua != null)
        {
            txtViewNome.text = itemTrocoRua.descritivo
        }

        return convertView
    }

    private val filtroTarifa: Filter = object : Filter() {
        override fun performFiltering(constraint: CharSequence?): FilterResults {
            val suggestions: MutableList<ModTrocoRua> = ArrayList()

            if (constraint.isNullOrEmpty()) {
                suggestions.addAll(fullLista)
            } else {
                val filterPattern: String = constraint.toString().toLowerCase(Locale.ROOT).trim()

                fullLista.forEach {
                    if (it.descritivo.toLowerCase(Locale.ROOT).contains(filterPattern)) {
                        suggestions.add(it)
                    }
                }
            }

            val results = FilterResults()

            results.values = suggestions
            results.count = suggestions.size

            return results
        }

        override fun publishResults(constraint: CharSequence?, results: FilterResults?) {
            val gson = Gson()

            clear()

            val resource = gson.toJson(results!!.values)

            val listType = object :
                TypeToken<ArrayList<ModTrocoRua>>() {}.type

            val values: ArrayList<ModTrocoRua> =
                gson.fromJson(
                    resource,
                    listType
                )

            addAll(values)
            notifyDataSetChanged()
        }

        override fun convertResultToString(resultValue: Any?): CharSequence {
            return (resultValue as ModTrocoRua).descritivo
        }
    }
}

一切正常，除了当我单击箭头时，仅显示一个建议。

如果再次单击箭头，一切正常。

这是非常奇怪的行为，我找不到解决它的方法。

此外，我想摆脱多余的压力

有没有建议？
