拨打电话的关键有两个方面，首先看，要在AndroidManifest中添加user-permission,并声明Android.permission.CALL_PHONE权限。由于拨打电话属于手机底层的服务，和用户隐私，通话费用等信息都息息相关，因此，程序必须取得相关权限。

package org.hwq.ex5_phone;import android.app.Activity;import android.content.Intent;import android.net.Uri;import android.os.Bundle;import android.view.View;import android.widget.Button;public class Main extends Activity {Button b;    /** Called when the activity is first created. */    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);        b = (Button) findViewById(R.id.button1);        b.setOnClickListener(new Button.OnClickListener(){@Overridepublic void onClick(View arg0) {// TODO Auto-generated method stubIntent intent = new Intent(Intent.ACTION_CALL,Uri.parse("tel:10086"));startActivity(intent);}                });    }}

AndroidManifest中添加打电话权限

<uses-permission android:name="android.permission.CALL_PHONE"/>

<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android"    package="org.hwq.ex5_phone"    android:versionCode="1"    android:versionName="1.0" >    <uses-sdk android:minSdkVersion="10" />    <uses-permission android:name="android.permission.CALL_PHONE"/>    <application        android:icon="@drawable/ic_launcher"        android:label="@string/app_name" >        <activity            android:name=".Main"            android:label="@string/app_name" >            <intent-filter>                <action android:name="android.intent.action.MAIN" />                <category android:name="android.intent.category.LAUNCHER" />            </intent-filter>        </activity>    </application></manifest>
