用这两个控件
分别实现这两个:
package com.example.autocomplete;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.widget.ArrayAdapter;
import android.widget.AutoCompleteTextView;
import android.widget.MultiAutoCompleteTextView;
public class MainActivity extends Activity {
private AutoCompleteTextView acTextView;
private String[] res = {"xxz1","xxz2","xxz3","shanghai1","shanghai2"};
private MultiAutoCompleteTextView MulacTextView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
acTextView = (AutoCompleteTextView) findViewById(R.id.autoCompleteTextView1);
//需要适配器
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,res);
//初始数据源,去匹配文本框中输入的内容,然后绑定
acTextView.setAdapter(adapter);
MulacTextView = (MultiAutoCompleteTextView) findViewById(R.id.multiAutoCompleteTextView1);
MulacTextView.setAdapter(adapter);
//设置以逗号为分隔符结束的符号
MulacTextView.setTokenizer(new MultiAutoCompleteTextView.CommaTokenizer());
}
布局文件:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<AutoCompleteTextView
android:hint="请输入搜索的关键词"
android:completionThreshold="3"
android:id="@+id/autoCompleteTextView1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
>
</AutoCompleteTextView>
<MultiAutoCompleteTextView
android:hint="请输入搜索的邮件关键词"
android:id="@+id/multiAutoCompleteTextView1"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
</MultiAutoCompleteTextView>
<CheckBox
android:id="@+id/checkBox1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="CheckBox" />
</LinearLayout>
