AutocompleteTextview

==>

使用比较容易，只需要为其设置一个Adapter，该Adapter封装其需要预设的文本内容。

如下所示实例：

<RelativeLayout xmlns:android=""xmlns: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=".IndexActivity" ><AutoCompleteTextView android:id="@+id/autoText"android:layout_width="match_parent"android:layout_height="wrap_content"android:completionHint="请选择你喜欢的书籍"android:dropDownHorizontalOffset="20dp"android:completionThreshold="1"/></RelativeLayout>

package com.example.myautocompletetextview;import android.os.Bundle;
import android.app.Activity;
import android.util.Log;
import android.view.Menu;
import android.widget.ArrayAdapter;
import android.widget.AutoCompleteTextView;public class IndexActivity extends Activity
{@Overrideprotected void onCreate(Bundle savedInstanceState){super.onCreate(savedInstanceState);setContentView(R.layout.index);Log.i("swg", "autocompletetextview");String[] books ={ "孙悟空大战红孩儿", "小兵张嘎", "三毛流浪记", "鲁宾逊漂流记", "android高级编辑" };ArrayAdapter<String> temp = new ArrayAdapter<String>(this,android.R.layout.simple_dropdown_item_1line, books);AutoCompleteTextView txtView = (AutoCompleteTextView) this.findViewById(R.id.autoText);// 设置AdaptertxtView.setAdapter(temp);}@Overridepublic boolean onCreateOptionsMenu(Menu menu){getMenuInflater().inflate(R.menu.index, menu);return true;}}
