     首先简单介绍一下sip协议，sip是会话启动协议，主要用于网络多媒体通话。必须是android2.3或其以上版本才可以调用Sip api，并且设备必须支持sip才可以进行sip通话。

 

SIP使用的api主要放在android.net.sip中，其中最核心的类为SipManager.java，关系图如下所示：

        本地的SipProfile存放在一个xml文件中，主要用于保存sip的username,domain和password，SharedPreference配置文件如下所示：

 

[html] view plain copy print ?

1. <PreferenceScreenxmlns:android="http://schemas.android.com/apk/res/android"> 
2.     <EditTextPreference 
3.         android:name="SIP Username" 
4.         android:summary="Username for your SIP Account" 
5.         android:defaultValue="" 
6.         android:title="Enter Username" 
7.         android:key="namePref"/> 
8.     <EditTextPreference 
9.         android:name="SIP Domain" 
10.         android:summary="Domain for your SIP Account" 
11.         android:defaultValue="" 
12.         android:title="Enter Domain" 
13.         android:key="domainPref"/> 
14.     <EditTextPreference 
15.         android:name="SIP Password" 
16.         android:summary="Password for your SIP Account" 
17.         android:defaultValue="" 
18.         android:title="Enter Password" 
19.         android:key="passPref" 
20.         android:password="true"  
21.         /> 
22. </PreferenceScreen> 

<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
    <EditTextPreference
        android:name="SIP Username"
        android:summary="Username for your SIP Account"
        android:defaultValue=""
        android:title="Enter Username"
        android:key="namePref" />
    <EditTextPreference
        android:name="SIP Domain"
        android:summary="Domain for your SIP Account"
        android:defaultValue=""
        android:title="Enter Domain"
        android:key="domainPref" />
    <EditTextPreference
        android:name="SIP Password"
        android:summary="Password for your SIP Account"
        android:defaultValue=""
        android:title="Enter Password"
        android:key="passPref"
        android:password="true" 
        />
</PreferenceScreen>

更新SharedPreference的代码如下：

 

[java] view plain copy print ?

1. publicvoid updatePreferences() { 
2.         Intent settingsActivity = new Intent(getBaseContext(), 
3.                 SipSettings.class); 
4.         startActivity(settingsActivity); 
5.     } 

public void updatePreferences() {
        Intent settingsActivity = new Intent(getBaseContext(),
                SipSettings.class);
        startActivity(settingsActivity);
    }

调用updatePreferences()方法会有如下的效果图显示：

通过此界面可以修改本地的SipProfile帐号信息。

接打电话时需要更新对方SipProfile的信息，代码如下：

 

[java] view plain copy print ?

1. /**

6.         // Be a good citizen.  Make sure UI changes fire on the UI thread. 
7.         this.runOnUiThread(new Runnable() { 
8.             publicvoid run() { 
9.                 TextView labelView = (TextView) findViewById(R.id.sipLabel); 
10.                 labelView.setText(status); 
11.             } 
12.         }); 
13.     } 
14.  
15.     /**

18.      */ 
19.     publicvoid updateStatus(SipAudioCall call) { 
20.         String useName = call.getPeerProfile().getDisplayName(); 
21.         if(useName == null) { 
22.           useName = call.getPeerProfile().getUserName(); 
23.         } 
24.         updateStatus(useName + "@" + call.getPeerProfile().getSipDomain()); 
25.     } 

/**

     */
    public void updateStatus(final String status) {
        // Be a good citizen.  Make sure UI changes fire on the UI thread.
        this.runOnUiThread(new Runnable() {
            public void run() {
                TextView labelView = (TextView) findViewById(R.id.sipLabel);
                labelView.setText(status);
            }
        });
    }

    /**
     * Updates the status box with the SIP address of the current call.
     * @param call The current, active call.
     */
    public void updateStatus(SipAudioCall call) {
        String useName = call.getPeerProfile().getDisplayName();
        if(useName == null) {
          useName = call.getPeerProfile().getUserName();
