Question

我试图制作一个应用程序，在其中我尝试获取已登录用户的个人资料照片。

当我进入我加载图片的视图并且我无法理解错误时，我有一个很长的错误。

错误是：

似乎错误来自于我试图在这里使用的ProfilePictureView类：

    ProfilePictureView currentUser;
    currentUser = (ProfilePictureView) findViewById(R.id.currentUser);
    currentUser.setProfileId(Profile.getCurrentProfile().getId());

我导入了这个类（我正在使用AndroidStudio）我认为可能是错误的根源是XML，它就在这里：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="@dimen/nav_header_height"
xmlns:facebook="http://schemas.android.com/tools"
android:background="@drawable/side_nav_bar"
android:gravity="bottom"
android:orientation="vertical"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:theme="@style/ThemeOverlay.AppCompat.Dark">

<com.facebook.widget.ProfilePictureView
    android:id="@+id/currentUser"
    android:layout_width="68dp"
    android:layout_height="wrap_content"
    android:paddingTop="8dp"
    android:gravity="center_horizontal"
    facebook:preset_size="small" />
<TextView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:paddingTop="@dimen/nav_header_vertical_spacing"
    android:text="Android Studio"
    android:textAppearance="@style/TextAppearance.AppCompat.Body1" />

<TextView
    android:id="@+id/textView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="android.studio@android.com" />

</LinearLayout>

我仍然在互联网上查看错误，但我是一个伟大的Android世界的初学者，所以如果有人能帮助我，那就太棒了！

非常感谢！

在facebook sdk 4.0.1中，ProfilePictureView类不在com.facebook.widget包中。它位于com.facebook.login.widget包中。所以你的xml声明应如下所示：

<com.facebook.login.widget.ProfilePictureView
    android:id="@+id/currentUser"
    android:layout_width="68dp"
    android:layout_height="wrap_content"
    android:paddingTop="8dp"
    android:gravity="center_horizontal"
   facebook:preset_size="small"/>

扩展类com.facebook.widget.ProfilePictureView时出错
