推荐答案

您可以这样做：

<ScrollView android:id="@+id/ScrollView02" 
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content"
        xmlns:android="http://schemas.android.com/apk/res/android">

<LinearLayout
    ....
>
 <textview  ...yourtextview   >
 ...
</LinearLayout>

</ScrollView>

有关你问题的第二部分，我认为你必须添加的android：点击=真正的来所有的textViews和处理与code。

For the second part of your question, I think you have to add android:clickable="true" to all your textViews and handle that with code.

另外，你可以使用一个ListView中 setOnItemClickListener（新OnItemClickListener（），这种方式更容易...

Otherwise, you could use a ListView with the setOnItemClickListener(new OnItemClickListener(), in this way it's easier ...
