Android实现搜索框内自动完成文本框
xml文件代码如下:
1 <?xml version="1.0" encoding="utf-8"?> 2 <LinearLayout 3 xmlns:android="http://schemas.android.com/apk/res/android" 4 android:orientation="vertical" 5 android:layout_width="fill_parent" 6 android:layout_height="fill_parent"> 7 8 <AutoCompleteTextView 9 android:id="@+id/myAutoCompleteTextView" 10 android:layout_width="fill_parent" 11 android:layout_height="wrap_content" /> 12 13 </LinearLayout>
java文件代码如下:
1 package com.example.sample_5_1; 2 3 import android.support.v7.app.AppCompatActivity; 4 import android.os.Bundle; 5 import android.widget.ArrayAdapter; 6 import android.widget.AutoCompleteTextView; 7 8 public class AutoCompleteActivity extends AppCompatActivity { 9 private static final String[] myStr = new String[]{ 10 "vae","victory","vision","virtue","vital" 11 }; 12 @Override 13 protected void onCreate(Bundle savedInstanceState) { 14 super.onCreate(savedInstanceState); 15 setContentView(R.layout.activity_auto_complete); 16 ArrayAdapter<String> aa = new ArrayAdapter<String>( //创建适配器 17 this, // Context 18 android.R.layout.simple_dropdown_item_1line, 19 //使用Android自带的简单布局 20 myStr); //资源数组 21 AutoCompleteTextView myAutoCompleteTextView = 22 (AutoCompleteTextView) findViewById(R.id.myAutoCompleteTextView); 23 //得到控件的引用 24 myAutoCompleteTextView.setAdapter(aa); //设置适配器 25 myAutoCompleteTextView.setThreshold(1); //定义需要用户输入的字符数 26 } 27 }
效果图如下:(输入一个V会自动提示以V开头的所有内容)
