我正在尝试创建一个包含 Spinner 的 UI。这是 XML(微调器快要结束了):
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<LinearLayout style="@style/header" >
<Button
android:id="@+id/btnBack_profileEdit"
style="@style/header_button"
android:layout_gravity="center_vertical"
android:layout_margin="@dimen/default_button_padding"
android:background="@drawable/ic_button"
android:drawableLeft="@drawable/ic_back_arrow"
android:gravity="right|center_vertical"
android:text="@string/back"
android:textColor="@android:color/white"
android:textSize="@dimen/header_button_text" />
<TextView
android:id="@+id/title_profileEdit"
style="@style/header_text"
android:singleLine="true"
android:text="@string/my_profile" />
<ImageButton
android:id="@+id/btnSave_profileEdit"
style="@style/header_button"
android:src="@drawable/ic_add" />
</LinearLayout>
<LinearLayout

<TextView

<EditText

android:imeOptions="actionNext" />
</LinearLayout>
<LinearLayout

android:background="@drawable/white_gradient" >
<TextView

android:text="@string/last_name"
android:textColor="@color/black_text" />
<EditText
android:id="@+id/lastName_profileEdit"
style="@style/profile_row_edit_text"
android:imeOptions="actionNext" />
</LinearLayout>
<LinearLayout

android:background="@drawable/white_gradient" >
<TextView

android:text="@string/email"
android:textColor="@color/black_text" />
<EditText
android:id="@+id/email_profileEdit"

</LinearLayout>
<LinearLayout

android:background="@drawable/white_gradient" >
<TextView

<EditText

android:imeOptions="actionNext"
android:inputType="textPassword" />
</LinearLayout>
<LinearLayout
android:id="@+id/lytRole_profileEdit"
style="@style/row"
android:background="@drawable/white_gradient" >
<TextView
style="@style/profile_row_content"
android:text="@string/role"
android:textColor="@color/black_text" />
<Spinner
android:id="@+id/role_profileEdit"
android:layout_width="match_parent"
android:gravity="center_vertical"
android:layout_height="wrap_content"
android:layout_weight=".5"
android:entries="@string/role" />
</LinearLayout>
<LinearLayout
android:id="@+id/lytSeparator_profileEdit"
style="@style/separator" >
<TextView
style="@style/separator_content"
android:text="@string/nickname_for_my_profile" />
</LinearLayout>
<LinearLayout
style="@style/row"
android:id="@+id/lytNickname_profileEdit"
android:background="@drawable/white_gradient" >
<TextView
style="@style/profile_row_content"
android:text="@string/nickname"
android:textColor="@color/black_text" />
<EditText
android:id="@+id/nickname_profileEdit"
style="@style/profile_row_edit_text"
android:layout_height="wrap_content" />
</LinearLayout>
</LinearLayout>
现在,当我尝试启动活动时,在扩展此布局时应用程序崩溃并且错误是:
Binary XML file line #105: Error inflating class android.widget.Spinner
是什么原因?
