Problem is automatically reset scroll view

 

android: id = "@ + id/h_scrollview_1" 
android: layout_width = "match_parent" 
android: layout_height = "100sp" 
android: background = "# 778899" 
> 
android: id = "@ + id/linearlayout_1" 
android: layout_width = "match_parent" 
android: layout_height = "match_parent" 
android: background = "# 778899" 
android: orientation = "horizontal" 
> 

 
 

android: id = "@ + id/v_scrollview_1" 
android: layout_width = "match_parent" 
android: layout_height = "match_parent" 
android: background = "# 998877" 
android: layout_below = "@ + id/h_scrollview_1" 
> 

android: id = "@ + id/relativelayout_1" 
android: layout_width = "match_parent" 
android: layout_height = "match_parent" 
android: background = "# 007f7f" 
> 

 
 

As shown in yellow font, I use the xml in a horizontal scroll bar, and a vertical scroll bar, hoping accounted for one-third of the horizontal scroll bar, two-thirds of the vertical scroll bar in the xml file I do not know how to specify parameters, just write a 100sp, think again to update the program based on the pixel size of the screen.

At the prompt Logcat, the horizontal scroll bar is displayed by default 172 height, I used after layout is set to 283, the last line and automatically reverts to 172, I do not know what is the reason?

Do not use the layout settings reliable?

HorizontalScrollView the android: layout_weight = 2, ScrollView in android: layout_weight = 1, They the android: layout_height = "match_parent".
But there you have other LinearLayout and RelativeLayout, may affect the results.
Try it.
