只是为了说明问题，我是并非使用Google 的所有！所有其他问题都使用该API，并且与我无关。android.view.InflateException：错误膨胀类的片段？
总之：
我的布局（风景）：
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<fragment
android:id="@+id/questionFragment"
android:name="com.liamw.school.flashcards.QuestionFragment"
android:layout_width="186dp"
android:layout_height="match_parent"

</RelativeLayout>
布局（肖像）：
<?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"
tools:layout="@android:layout/list_content" />
</LinearLayout>
主要活动：
package com.liamw.school.flashcards;
import android.app.Activity;
import android.os.Bundle;
public class MainAppActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.app_main_activity);
}
}

我想不通为什么发生错误。完整的logcat：

我是相当新的碎片，所以很抱歉，可能很简单的问题。如果您需要任何其他文件，只需在评论中提问即可。
对不起，但我真的找不到答案！
