发生错误原因分析：

ScrollView仅支持一个子项。

查看对应的layout xml，发现ScrollView中有两个子项。

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="fill_parent" android:layout_height="wrap_content"android:scrollbars="vertical"><TextView android:id="@+id/textView2" android:layout_gravity="center"android:layout_width="fill_parent" android:layout_height="wrap_content"android:text="@string/text_CRdesc_title"></TextView><TextView android:id="@+id/textView2" android:layout_gravity="center"android:layout_width="wrap_content" android:layout_height="wrap_content"android:text="@string/text_CRdesc"></TextView></ScrollView>

解决办法：

在ScrollView 中设LinearLayout为子项，将其它View放入LinearLayout。

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="fill_parent" android:layout_height="wrap_content"android:scrollbars="vertical"><LinearLayout android:id="@+id/linearLayout1"android:layout_width="fill_parent" android:layout_height="wrap_content"android:orientation="vertical"><TextView android:id="@+id/textView2"android:layout_gravity="center" android:layout_width="fill_parent"android:layout_height="wrap_content" android:text="@string/text_CRdesc_title"></TextView><TextView android:id="@+id/textView2"android:layout_gravity="center" android:layout_width="wrap_content"android:layout_height="wrap_content" android:text="@string/text_CRdesc"></TextView></LinearLayout></ScrollView>

PS. 在Error Log中有错误提示。但在编辑layout xml 时未开启“Error Log”窗口，未发现报错。

其实“Graphical Layout” 中也会有报错提示

ScrollView can host only one direct childException details are logged in Window > Show View > Error Log
