我有一个edittext,可以从用户那里获取值。我想添加一个选项,允许用户在单击edittext时通过下拉列表从不同选项中进行选择。有没有人知道如何做到这一点?

这是edittext代码:

<EditText
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:inputType="textPersonName"
    android:ems="10"
    android:id="@+id/dish_quantity"
    android:layout_below="@+id/dish_name"
    android:layout_alignParentRight="true"
    android:layout_alignParentEnd="true"
    android:hint="Quantity" />

我希望它看起来像这样:

我认为这是你的要求:

按照这个例子: 的 XML: -

new Dragger(barItem,itemToDrag);

<强>活动: -

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >   
<AutoCompleteTextView
    android:id="@+id/languages"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"></AutoCompleteTextView>
</LinearLayout>

activity_main.xml中

<RelativeLayout xmlns:androclass="http://schemas.android.com/apk/res/android"  
    xmlns:tools="http://schemas.android.com/tools"  
    android:layout_width="match_parent"  
    android:layout_height="match_parent"  
    tools:context=".MainActivity" >  

    <TextView  
        android:id="@+id/textView1"  
        android:layout_width="wrap_content"  
        android:layout_height="wrap_content"  
        android:layout_alignParentLeft="true"  
        android:layout_alignParentTop="true"  
        android:layout_marginTop="15dp"  
        android:text="@string/what_is_your_favourite_programming_language_" />  

    <AutoCompleteTextView  
        android:id="@+id/autoCompleteTextView1"  
        android:layout_width="wrap_content"  
        android:layout_height="wrap_content"  
        android:layout_alignParentLeft="true"  
        android:layout_below="@+id/textView1"  
        android:layout_marginLeft="36dp"  
        android:layout_marginTop="17dp"  
        android:ems="10"  
        android:text="">  

        <requestFocus />  
    </AutoCompleteTextView>  

</RelativeLayout>

MainActivity.java

import android.os.Bundle;  
import android.app.Activity;  
import android.graphics.Color;  
import android.view.Menu;  
import android.widget.ArrayAdapter;  
import android.widget.AutoCompleteTextView;  

public class MainActivity extends Activity {  
    String[] language ={"C","C++","Java",".NET","iPhone","Android","ASP.NET","PHP"};  
    @Override  
    protected void onCreate(Bundle savedInstanceState) {  
        super.onCreate(savedInstanceState);  
        setContentView(R.layout.activity_main);  

        //Creating the instance of ArrayAdapter containing list of language names  
           ArrayAdapter<String> adapter = new ArrayAdapter<String>  
            (this,android.R.layout.select_dialog_item,language);  
        //Getting the instance of AutoCompleteTextView  
           AutoCompleteTextView actv= (AutoCompleteTextView)findViewById(R.id.autoCompleteTextView1);  
           actv.setThreshold(1);//will start working from first character  
           actv.setAdapter(adapter);//setting the adapter data into the AutoCompleteTextView  
           actv.setTextColor(Color.RED);  

    }  

    @Override  
    public boolean onCreateOptionsMenu(Menu menu) {  
        // Inflate the menu; this adds items to the action bar if it is present.  
        getMenuInflater().inflate(R.menu.activity_main, menu);  
        return true;  
    }  

}
