How to add a friend in an Android App?

Question

In my phone contact book, When I click on any of the contact, it displays the contact name and the phone number in the logcat, which are passed to the server as parameters of a POST call. What I want is, the moment I click on any contact, it should be added in my friend list as well.

Now, clicking on contact, gives me the name and number, how do I display this name in the form of a picture, so that the user can see that a friend has been added in his friend list.

Just to make my question more clear, when someone doesn't have a profile picture on facebook, and when you add this person as a friend, his name is displayed along with the image of human form. I want to achieve this in my App.

在您的图形对象中存储一个虚拟图像，如果用户没有照片，则只需使用该虚拟图像即可。
