<Button

android:id="@+id/but1"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:text="Call"

package com.sun.hello;

import android.app.Activity;

import android.content.Intent;

import android.location.GpsStatus.Listener;

import android.net.Uri;

import android.os.Bundle;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.Button;

import android.widget.Toast;

public class HelloActivity extends Activity {

private Button button = null;

/** Called when the activity is first created. */

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

button = (Button) findViewById(R.id.but1);

button.setOnClickListener(listener);

}

private OnClickListener listener=new OnClickListener() {

public void onClick(View v) {

// TODO Auto-generated method stub

Intent intent =new Intent(); //new一个意图

intent.setAction(Intent.ACTION_CALL);//动作

intent.setData(Uri.parse("tel:15226513509"));//设置电话号码

startActivity(intent);//启动

}

};

}
