Android Technology Summary (004) -- set components in ScrollView to android: layout_height = &

For example, the components added to the ScrollView cannot be automatically scaled to the screen height in any way.

Layout file.

[Html]
<? Xml version = "1.0" encoding = "UTF-8"?>
<! -- Background: blue -->
<ScrollView xmlns: android = "http://schemas.android.com/apk/res/android"
Android: id = "@ + id/scrollView1"
Android: layout_width = "fill_parent"
Android: layout_height = "fill_parent"
Android: background = "# 0000ff">
 
<! -- Background: Green -->
 
<LinearLayout
Android: id = "@ + id/linearLayout1"
Android: layout_width = "fill_parent"
Android: layout_height = "fill_parent"
Android: background = "#00ff00">
 
<TextView
Android: id = "@ + id/textView1"
Android: layout_width = "wrap_content"
Android: layout_height = "fill_parent"
Android: layout_weight = "1"
Android: text = "Hello Android.">
</TextView>
</LinearLayout>
 
</ScrollView>

.

Although android: layout_height = "fill_parent" has been set, the entire LinearLayout and TextView cannot be filled with the entire screen.

Solution.

Add an android: fillViewport = "true" attribute to ScrollView. As the name suggests, this attribute allows components in ScrollView to fill it.

Modified.
