我想在列表视图中添加朋友的个人资料图片及其姓名。我正在使用在列表视图中给我朋友名字的代码。但我不知道如何显示他们的个人资料图片。我使用了登录按钮，并在其点击事件上打开好友列表。谁能告诉我。？这是我用过的代码

     public class LoginActivity extends Activity{

       public static final String APP_ID = "*************";
       private Facebook facebook = new Facebook(APP_ID);
       private AsyncFacebookRunner mAsyncRunner = new AsyncFacebookRunner(facebook);

      String FILENAME = "AndroidSSO_data";
      private SharedPreferences mPrefs;

      public static ArrayList<String> friends ;
      String _error;

                        this.requestWindowFeature(Window.FEATURE_NO_TITLE);
                    getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
        setContentView(R.layout.login);
       friends= new ArrayList<String>();

      tv=(TextView)LoginActivity.this.findViewById(R.id.textview1);

                    loginButton.setOnClickListener(new View.OnClickListener() {

                      @Override
                          public void onClick(View v) {

您必须仅显示带有 URL 的朋友的头像。

您必须仅使用 URL 来显示您的 frnds 个人资料图片。（此功能由 Facebook 提供）

您可以使用延迟加载显示您朋友的个人资料图片..
