自学android——AutoCompleteTextView的使用

在慕课网上学习的

AutoCompleteTextView

代码如下

package com.example.admin.test_20160306;import android.support.v7.app.AppCompatActivity;import android.os.Bundle;import android.widget.ArrayAdapter;import android.widget.AutoCompleteTextView;public class MainActivity extends AppCompatActivity {    private AutoCompleteTextView autoCompleteTextView;    private String[] res={"skk1","skk2","skk3","skk4"};    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        autoCompleteTextView=(AutoCompleteTextView)findViewById(R.id.autoCompleteTextView);        ArrayAdapter<String> adapter=new ArrayAdapter<String>(this,R.layout.support_simple_spinner_dropdown_item,res);        autoCompleteTextView.setAdapter(adapter);    }}
layout很简单

<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:paddingBottom="@dimen/activity_vertical_margin"    android:paddingLeft="@dimen/activity_horizontal_margin"    android:paddingRight="@dimen/activity_horizontal_margin"    android:paddingTop="@dimen/activity_vertical_margin"    tools:context="com.example.admin.test_20160306.MainActivity">    <AutoCompleteTextView        android:completionThreshold="3"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:hint="New AutoCompleteTextView"        android:id="@+id/autoCompleteTextView"        android:textSize="20dp"        android:layout_alignParentTop="true"        android:layout_alignParentLeft="true"        android:layout_alignParentStart="true" /></RelativeLayout>
