我的Autocompletetextview的長文本完全顯示在屏幕上

Question

我需要的是，當用戶鍵入字符時，它應該顯示建議，並且該建議必須完全顯示在屏幕上。 顯示完整的文本或我的字符串的長文本在自動完成的第二行中連續顯示

package com.example.epson.buscadormep;

import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.AutoCompleteTextView;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        final String[] values = new String[]{"Cilindros pequeños de oxigeno gaseoso o de aire, de uso medicinal", "Dispositivos que contienen oxigeno liquido",
                "Cilindo de un gas de la dicivion 2.2 para activar las extremidades artiiciales mecanicas", "Articulos medicinales no radiactivos (incluso aerosoles)"};
        //final ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_dropdown_item_1line,values);
        final ArrayAdapter<String> adapter =new ArrayAdapter<String>(this,android.R.layout.simple_dropdown_item_1line,values);
        final AutoCompleteTextView autoCompleteTextView = (AutoCompleteTextView) findViewById(R.id.txtMercancias);
        autoCompleteTextView.setThreshold(1);//will start working from second character
        autoCompleteTextView.setAdapter(adapter); //setting the adapter data into the AutoCompleteTextView

        autoCompleteTextView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                // LinearLayout ll = (LinearLayout) view;
                //This will give you the string value of selected list item
                //TextView listItem = (TextView) ll.getChildAt(0);
                //You can do this or apply own logic to find the selected value case


                if (autoCompleteTextView.getText().toString().equals("Cilindros pequeños de oxigeno gaseoso o de aire, de uso medicinal"))
                {
                    startActivity(new Intent( MainActivity.this, Main2Activity.class));
                }
                if (autoCompleteTextView.getText().toString().equals("Dispositivos que contienen oxigeno liquido"))
                {
                    startActivity(new Intent( MainActivity.this, Main3Activity.class));
                }
                if (autoCompleteTextView.getText().toString().equals("Cilindo de un gas de la dicivion 2.2 para activar las extremidades artiiciales mecanicas"))
                {
                    startActivity(new Intent( MainActivity.this, Main4Activity.class));
                }
                if (autoCompleteTextView.getText().toString().equals("Articulos medicinales no radiactivos (incluso aerosoles)"))
                {
                    startActivity(new Intent( MainActivity.this, Main5Activity.class));
                };
            }
        });



    }
}

這是我的activity_main.xml ...我認為我必須解決此問題嗎？

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <TextView
        android:id="@+id/sample_text"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Mercancias Peligrosas: "
        android:clickable="true"
        android:onClick="onClick"/>

    <AutoCompleteTextView
        android:id="@+id/txtMercancias"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:hint="Escriba mercancias peligrosa"

        android:singleLine="false"
        android:ellipsize="end"
        android:maxLines="2"
        android:inputType="text"
        android:layout_gravity="center"
        android:paddingLeft="4dp"
        />


</LinearLayout>

嘗試為您為autoCompleteTextView設置的適配器使用自定義布局：

MainActivity.java

final ArrayAdapter adapter = new ArrayAdapter(this,R.layout.custom_autocomplete_item,R.id.autoCompleteItem, values);

custom_autocomplete_item.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent" >

   <TextView
    android:id="@+id/autoCompleteItem"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:padding="5dp"
    android:textSize="14sp"
    />

</LinearLayout>
