autoCompleteTextView用法简析

1,布局文件中定义AutoCompleteTextView组件

2,Activity中创建对布局文件中AutoCompleteTextView的引用

3,创建ArrayAdapter对象作为AutoCompleteTextView对象的资源文件

4,调用AutoCompleteTextView的setAdapter()方法

具体代码如下:

package com.sun.auto_complete_text_view_test;

import java.util.ArrayList;
import java.util.List;

import android.app.Activity;
import android.os.Bundle;
import android.widget.ArrayAdapter;
import android.widget.AutoCompleteTextView;

public class AutoCompleteTextViewTestActivity extends Activity {
    /** Called when the activity is first created. */
 AutoCompleteTextView autoCompleteTextView = null;
 private static final String[] COUNTRIES = new String[] {
        "Belgium", "France", "Italy", "Germany", "Spain"
    };

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        autoCompleteTextView = (AutoCompleteTextView)findViewById(R.id.auto_complete_text_view);
        ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_dropdown_item_1line, COUNTRIES);
        autoCompleteTextView.setAdapter(adapter);
    }
}
