Android开发便签3:TextView的自动检测文本中的超链接和自动补全

在Android中，TextView的一些应用小例子：

package com.andy.android;

import android.app.Activity;
import android.os.Bundle;
import android.text.util.Linkify;
import android.widget.ArrayAdapter;
import android.widget.AutoCompleteTextView;
import android.widget.TextView;
/**

 */
public class TestTextView extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        //1、自动检查超链接
        TextView tv = (TextView) findViewById(com.andy.android.R.id.textview);
        tv.setText("访问我的javaeye博客 http://andyzhchy.iteye.com/");
        Linkify.addLinks(tv, Linkify.ALL);
        
        //2、自动填充
        AutoCompleteTextView autoCompleteTextView = (AutoCompleteTextView)findViewById(R.id.auto_complete);   
        ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(this,   
                android.R.layout.simple_dropdown_item_1line,new String[]{   
                "aa", "ab", "bc", "de", "ac","aab"    
        });   
        autoCompleteTextView.setAdapter(arrayAdapter);   
    }
}

布局文件main.xml代码：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
	android:orientation="vertical" android:layout_width="fill_parent"
	android:layout_height="fill_parent">
	<TextView android:id="@+id/textview" android:layout_width="fill_parent"
		android:layout_height="40dip" />
	<AutoCompleteTextView android:id="@+id/auto_complete"
		android:layout_width="fill_parent" android:layout_height="wrap_content" />

</LinearLayout>
