程序如下所示：

import android.app.Activity;
import android.os.Bundle;
import android.text.util.Linkify;
import android.view.KeyEvent;
import android.view.View;
import android.view.View.OnKeyListener;
import android.widget.EditText;
import android.widget.TextView;

public class A02Activity extends Activity {
private TextView tv;
private EditText et;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
tv=(TextView)findViewById(R.id.tv);
et=(EditText)findViewById(R.id.et);
et.setOnKeyListener(new OnKeyListener(){

@Override
public boolean onKey(View v, int keyCode, KeyEvent event) {
// TODO Auto-generated method stub
tv.setText(et.getText());
Linkify.addLinks(tv, Linkify.PHONE_NUMBERS|Linkify.WEB_URLS|Linkify.EMAIL_ADDRESSES);
return false;
}

});
}
}

res/layout/main.xml如下：

< xml version="1.0" encoding="utf-8" >
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >

android:id="@+id/tv"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/hello" />
android:id="@+id/et"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>

也可以不在程序中用Linkify，而在res/layout/main.xml中使用android:autoLink="all"（这个适合所有的android手机支持的标识）或者是android:autoLink="web|phone|email"(这个支持指定的android手机支持的标识),具体举例如下：

import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;

public class A03Activity extends Activity {
TextView tv01,tv02,tv03;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
tv01=(TextView)findViewById(R.id.tv01);
tv02=(TextView)findViewById(R.id.tv02);
tv03=(TextView)findViewById(R.id.tv03);
tv01.setText("www.baidu.com");
tv02.setText("18775828658");
tv03.setText("1650967185@qq.com");
}
}

res/layout/main.xml如下所示：

< xml version="1.0" encoding="utf-8" >
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >

android:id="@+id/tv01"
android:autoLink="all"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/hello" />
android:id="@+id/tv02"
android:autoLink="all"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>
android:id="@+id/tv03"
android:autoLink="all"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>
