发生错误原因分析：
ScrollView仅支持一个子项。
查看对应的layout xml
Java代码
- <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/nokia" android:layout_gravity="center"
- android:layout_width="fill_parent" android:layout_height="wrap_content"
- android:textAppearance="?android:attr/textAppearanceMedium"
- android:text="@string/text_nokia"></TextView>
- <TextView android:id="@+id/iphone4s" android:layout_gravity="center"
- android:layout_width="wrap_content" android:layout_height="wrap_content"
- android:text="@string/text_iphone4s"></TextView>
- </ScrollView>
发现ScrollView中有两个TextView子项。
解决办法：
在ScrollView 中设LinearLayout为子项 ，将其它View放入LinearLayout。
Java代码
- <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/tmall"
- android:layout_width="fill_parent" android:layout_height="wrap_content"
- android:orientation="vertical">
- <TextView android:id="@+id/nokia" android:layout_gravity="center"
- android:layout_width="fill_parent" android:layout_height="wrap_content"
- android:textAppearance="?android:attr/textAppearanceMedium"
- android:text="@string/text_nokia"></TextView>
- <TextView android:id="@+id/iphone4s" android:layout_gravity="center"
- android:layout_width="wrap_content" android:layout_height="wrap_content"
- android:text="@string/text_iphone4s"></TextView>
- </LinearLayout>
- </ScrollView>
PS。在编辑layout xml时应注意“Error Log”窗口与layout xml编辑窗口的“Graphical Layout”选项卡。
