我试图在我的Android应用程序中使用this项目。
我的list_style.xml看起来像
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/libs/circularimageview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="center"
android:orientation="vertical" >
<com.mikhaellopez.circularimageview.CircularImageView
android:layout_width="48dp"
android:layout_height="48dp"
android:src="@drawable/kamilwirtek"
android:layout_gravity="left"
android:layout_margin="10dp"
android:id="@+id/avatar"
app:border="true"
app:border_color="#000000"
app:border_width="4dp"
app:shadow="true" />
<TextView
android:id="@+id/full_name"
android:layout_gravity="center"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="25dp"
android:textColor="#111111"
android:text="TextView" />
</LinearLayout>
当我正在运行应用程序时，我使用以下代码收到错误：

我正在使用Fragments。当我添加onCreateView时：
CircularImageView circularImageView = (CircularImageView)getActivity().findViewById(R.id.avatar);
circularImageView.setBorderColor(getResources().getColor(R.color.GrayLight));
circularImageView.setBorderWidth(10);
circularImageView.addShadow();
我的代码出现了另一个错误：

出了什么问题？我该如何解决这个问题？
答案 0 :(得分：0)
您正试图从活动的视图而不是片段中获取视图。
而不是：
CircularImageView circularImageView = (CircularImageView)getActivity().findViewById(R.id.avatar);
你应该做
CircularImageView circularImageView = (CircularImageView)view.findViewById(R.id.avatar);
片段＆＃39; onViewCreated(View,Bundle)
