LinearLayout not scrolling with ScrollView

I have a LinearLayout that has a lot of TextViews programatically put in. By a lot, I mean it extends beyond the bottom of my screen. I want to use a ScrollView to allow the user to scroll beyond the screen and see the rest of the TextViews. This is my activity_main.xml currently:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<LinearLayout
android:id="#+id/ll"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="61dp"
android:orientation="vertical" >
</LinearLayout>
</ScrollView>
Any help will be greatly appreciated! Thanks!

Try changing android:layout_width="wrap_content" to android:layout_width="match_parent"
<LinearLayout
android:id="#+id/ll"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginBottom="61dp"
android:orientation="vertical" >
</LinearLayout>
</ScrollView>

Change your code as below !
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<LinearLayout
android:id="#+id/ll"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="61dp"
android:orientation="vertical" >
</LinearLayout>
</ScrollView>
NOTE: To see if it is scrolling or not try placing some views inside linearLayout like buttons otherwise you won't notice the screen scrolling

Also You Can Do Like This.It Works Well.
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/scrollData"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:scrollbars="vertical" >
<LinearLayout
android:id="#+id/linearWhere"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="15dp"
android:orientation="vertical"
android:padding="5dp">
</LinearLayout>
</ScrollView>

Android LinearLayout with Button and FrameLayout using the Maximum Height

I am trying to make a layout where there are a LinearLayout and inside it I want a FrameLayout and a button.
I want the button to use the bottom of the linearlayout and to use the maximum width and the enough height for the button, using wrap content.
The other component, the FrameLayout I want to use it the remaining part of the screen.
How can I do it?
Here it the layout so far..
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:orientation="vertical" >
<FrameLayout
android:id="#+id/camera_preview"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
<Button
android:id="#+id/button_capture"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:onClick="snapIt"
android:text="#string/Capture" />
</LinearLayout>
Is not showing the button :s
Thanks alot in advance ;)

Better to work out with relative layout with button aligned to parent bottom and your frame layout above it occupying the rest space of the screen.Like this
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="match_parent" >
<FrameLayout
android:id="#+id/camera_preview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_above="#+id/button_capture"/>
<Button
android:id="#+id/button_capture"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:onClick="snapIt"
android:layout_alignParentBottom="true"/>
</RelativeLayout>

use the following xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:orientation="vertical" >
<Button
android:id="#+id/button_capture"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:onClick="snapIt"
android:layout_alignParentBottom="true"
android:text="capture" />
<FrameLayout
android:id="#+id/camera_preview"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:layout_above="#+id/button_capture"
/>
</RelativeLayout>

i am just trying to make these layout, after compare my layout code and your layout code, i find a different code, there is in my code. Did you missing it or just move it away cause it useless from the layout code ?
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button" />
<FrameLayout
android:id="#id/flayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/hello_world">
</FrameLayout>
</LinearLayout>

Android two latyout horizantally

i want to put two layouts horizantally, small layout on the right and the big on on the left
i tried like this
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal" >
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:background="#000000" >
</LinearLayout>
<LinearLayout
android:layout_width="10dip"
android:layout_height="fill_parent"
android:background="#ffffff" >
</LinearLayout>
</LinearLayout>
but still get the small one on the right, what should i do?

A LinearLayout displays its children in the order in which you add them: top to bottom = left to right, for a horizontal view and top to bottom for a vertical view. Change the order of the views in the XML and they will change on the screen.

Sorry to see your comment lately. But try this:
pseudo code(Untested):
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:weightsum = "10"
>
<LinearLayout
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="7"
android:background="#ffffff"
>
</LinearLayout>
<LinearLayout
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="3"
android:background="#000000"
>
</LinearLayout>
</LinearLayout>
You don't need to put orientation horizontal as it supports by default. Even there is no problem if you keep it as the other answerer said.

Try this :
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="fill_parent"
android:layout_weight="1"
android:background="#000000" >
</LinearLayout>
<LinearLayout
android:layout_width="20dip"
android:layout_height="fill_parent"
android:layout_weight="1"
android:background="#ffffff" >
</LinearLayout>
</LinearLayout>

How can I place new items under scrollview

I have a vertical scrollable layout with lots of items, working fine.
I am trying to place a new linearlayout to the bottom of the screen that would NOT be part of the scrollable layout.
That is, it would sit on the buttom (like an adview) independent of the scrollable part.
I was only able to place it inside the scrollView. How can I place it below, so it would always visible ?

Use a RelativeLayout, and organize it like this:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<ScrollView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_alignParentTop="true"
android:layout_above="#+id/linearLayoutThatDoesNotScroll" >
<LinearLayout
android:id="#+id/linearLayoutWithLotofContent"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal" >
</LinearLayout>
</ScrollView>
<LinearLayout
android:id="#+id/linearLayoutThatDoesNotScroll"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true" >
</LinearLayout>
</RelativeLayout>
The trick is in the ScrollView placement, at the same time it is aligned with the top of the screen AND above the lower, fixed, LinearLayout. It just works.

something like this :)
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<ScrollView android:id="#+id/scroll_view"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_weight="1" >
<LinearLayout android:id="#+id/content"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
</ScrollView>
<LinearLayout android:id="#+id/bottom"
android:layout_width="fill_parent"
android:layout_height="10dip" />
</LinearLayout>
You will add your bottom content to the bottom linearLayout with the android:id=bottom :)

If you used a vertical LinearLayout to hold the scrollable layout, then you could add the adview to the LinearLayout below the scrollable layout and it would appear at the bottom of the screen. (assuming your weights are set correctly,and the scroll layout is set to WRAP_CONTENT)
A RelativeLayout would allow you to set the adview to align itself with the bottom of the scrollable layout as well, but you would still need to make sure the scrollable layout was set to WRAP_CONTENT so it didn't automatically take up the entire screen.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<Button
android:id="#+id/dialogButtonOK"
android:layout_width="100px"
android:layout_height="wrap_content"
android:text=" Ok "
android:layout_alignParentBottom="true"
android:layout_centerInParent="true"
android:background="#drawable/button_style"
/>
<ScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="5dp"
android:id="#+id/scrView"
android:layout_above="#id/dialogButtonOK"
android:layout_alignParentTop="true"
>
<HorizontalScrollView
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<TableLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:stretchColumns="*"
android:id="#+id/main_table" >
</TableLayout>
</HorizontalScrollView>
</ScrollView>
</RelativeLayout>
This is worked for me

Android UI difficulties

My layout was perfect until I decided to add a scrollview.
<?xml version="1.0" encoding="utf-8"?>
<TableLayout android:id="#+id/tableLayout1" android:layout_width="fill_parent" android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android">
<ScrollView android:id="#+id/scrollView1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_weight="1" >
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" android:id="#+id/linearLayout1">
<TableLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:id="#+id/tableLayout1"/>
</LinearLayout>
</ScrollView>
<Button android:layout_width="match_parent" android:id="#+id/button1" android:text="Start" android:layout_height="50dip" android:onClick="getOutput"></Button>
</TableLayout>
I would like the button to stay at the bottom of the screen, I would actually like the scrollview to take up the entire screen. With just the inner table layout it works fine. In the Graphical Layout preview it looks how I want it, but not when I run it.
I would like the scrollview to take up the whole screen except the button, which I'd like to be at the bottom.

you could use RelativeLayout or LinearLayout as Root view. Giving Button more weight. That way ScrollView won't take up the whole thing.

this should work
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent" android:layout_height="fill_parent"
android:orientation="vertical">
<ScrollView android:layout_width="fill_parent" android:layout_height="0dip"
android:layout_weight="1.0">
<LinearLayout android:layout_width="fill_parent"
android:layout_height="fill_parent" android:orientation="vertical"
android:id="#+id/linearLayout1">
<TableLayout android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="#+id/tableLayout1"/>
</LinearLayout>
</ScrollView>
<Button android:layout_width="fill_parent" android:layout_height="wrap_content"
android:text="Bottom Button"/>
</LinearLayout>

Try setting ScrollView fillViewport attribute to true.
