您可以撥打此:

Intent i = new Intent(); 
i.setComponent(new ComponentName("com.android.contacts", 
        "com.android.contacts.ExportVCardActivity")); 
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 
startActivity(i); 

所需的權限:

android.permission.READ_CONTACTS 
android.permission.WRITE_EXTERNAL_STORAGE 
android.permission.WRITE_CONTACTS
