Ask a young girl LinearLayout layout problems!

Request a layout wording. Probably this is the description!

Overall a LinearLayout contains three LinearLayout.
Three hours.

The first LinearLayout should always at the top.
The second LinearLayout to the middle.
In the middle of this LinearLayout sure to include other layouts, such as putting a ListView, can slide up and down. Not cover third LinearLayout.
The third LinearLayout should always at the bottom.

| ------------------------ |
| Button button | <- first LinearLayout
| ------------------------ |
| |
| Only within this area | <- second LinearLayout
| Slide up and down without affecting |
| Other Layout |
| ------------------------ |
| Button button | <- third LinearLayout
| ------------------------ |

Probably this is the description please advise seniors! If there are other methods can also be a good idea to inform me.

Thank you.

android: layout_width = "fill_parent" android: layout_height = "fill_parent" 
android: orientation = "vertical" xmlns: android = "http://schemas.android.com/apk/res/android">

If you want only in this region, sliding up and down, without affecting the other layouts, I recommend the middle of the layout of a fixed size should! For example, much higher, width can fill_parent

Not fixed, but the layout is not recommended to use the value written dead.

You try, the second layout: android: layout_height = "wrap_content" android: layout_weight = "1.0"
Two other high-android: layout_height = "wrap_content"

I would like to do.

This is one way, in fact, as the landlord as you can.

I have no problem directly with the LinearLayout.

RelativeLayout
There's layout relative to the parent window, plus two properties as long as you can in the child window relative to the parent window layout of
android: layout_alignParentTop = "true"
android: layout_alignParentBottom = "true"

Xml based on your modified:

 
 
android: layout_width = "fill_parent" 
android: layout_height = "fill_parent" 
xmlns: android = "http://schemas.android.com/apk/res/android"> 
android: layout_width = "fill_parent" 
android: layout_height = "wrap_content" 
 android: layout_alignParentTop = "true" 
android: layout_alignParentLeft = "true"  
android: background = "# ffff0000" 
> 

Relative layout or a good use!
