loginButton=(Button)findViewById(R.id.button_login);
loginButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (! facebook.isSessionValid()) {
facebook.authorize(LoginActivity.this, PERMISSIONS, new LoginDialogListener());
}
}
});
}

答案 0 :(得分：3)
您必须仅使用网址显示朋友的个人资料照片。
您只需使用网址来显示您的frnds个人资料图片。（此工具由Facebook提供）
您可以使用延迟加载 ..
