android can't display the bottom of the layout

I made an android app that contain scrollview layout and inside it AbsoluteLayout, the problem is I can't display the bottom of the layout it only display the top of the layout. I tried to use layout_marginBottom in the AbsoluteLayout but it didn't work.

Use RelativeLayout instead of AbsoluteLayout. Also don't scroll the total layout. Just scroll the View only.
Check it once:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:layout_marginLeft="40dp"
android:layout_marginRight="40dp"
android:layout_marginTop="40dp"
android:background="#drawable/bg" >
<ScrollView
android:layout_width="match_parent"
android:layout_height="300dp" >
<TextView
android:id="#+id/textView1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="TextView" />
</ScrollView>
<Button
android:id="#+id/btn1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:text="Button" />
<TextView
android:id="#+id/textView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_above="#+id/btn1"
android:layout_centerHorizontal="true"
android:layout_marginBottom="27dp"
android:text="#string/s3"
android:textSize="16sp"
android:text="TextView" />
</RelativeLayout>

Use RelativeLayout and set left and right margins like
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);
lp.leftMargin = x;
lp.topMargin = y;

True , absolute layout is deprecated . Also , here is a tip :
When creating an xml layout for Android , the easiest way to check for error is using the "graphical layout" tab of the xml layout file . . Use an appropriate device configuration ( match your device ) and the API version , reproduce that error and see if changing the layout parameters help .

use property android:fillViewPort=true inside ScrollView as follows
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:fillViewport="true"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/bg"
android:orientation="vertical" >

Android: Draw line behind ImageView in list item

I would like to draw a line behind an ImageView in a list item which fills the entire height of the list item. The image in the following link shows my desired result. The blue line is the one I want.
https://www.dropbox.com/s/fbdsuvcyxaz1pnj/listViewDesired.png?dl=0
I have a ListView with a custom adapter and layout for each row. The row is comprised of a relative layout with a few elements: an image with a specific size anchored to the left, a text view with a specific size anchored to the right, and a text view which fills the rest of the space in between.
I want to show a thin line coming out of the top and bottom of the ImageView and fill the rest of the space for that list item. The List item's size can become larger than the image size if there is a lot of text in the middle. How can I achieve this?
I have tried multiple approaches with a framelayout with a view that matches/fills the parent and the ImageView, and a linearlayout with 3 views (top line, imageView, bottom line that fills the parent), and the image looks correct in the IDE render, but the lines do not extend all the way or even show up when the app is actually running.
This is my layout without a line behind the imageview.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:padding="#dimen/marginTop"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<!--Line should be "behind" (extending from top and bottom) of this imageView and should extend to the full height of the RelativeLayout after it has been rendered-->
<ImageView
android:id="#+id/tabIcon"
android:src="#drawable/face"
android:layout_marginTop="#dimen/margin"
android:layout_width="#dimen/catchSize"
android:layout_height="#dimen/catchSize"/>
<TextView
android:id="#+id/tabUpdateTime"
android:layout_marginLeft="#dimen/margin"
android:layout_alignParentRight="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
<TextView
android:id="#+id/tabText"
android:text="#string/long_string"
android:layout_marginLeft="#dimen/margin"
android:layout_marginRight="#dimen/margin"
android:layout_toRightOf="#id/tabIcon"
android:layout_toLeftOf="#id/tabUpdateTime"
android:layout_width="fill_parent"
android:layout_height="wrap_content"/>
</RelativeLayout>

You just need to create separate layout for Image as well as Vertical Line and to draw Vertical Line you need to add a View with width of 1dp or the thickness you want.
Try with the following Code :
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<!-- Line should be "behind" (extending from top and bottom) of this imageView and should extend to the full height of the RelativeLayout after it has been rendered -->
<RelativeLayout
android:id="#+id/image"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottom="#+id/tabText" >
<View
android:id="#+id/verticleLine"
android:layout_width="1dp"
android:layout_height="match_parent"
android:layout_centerInParent="true"
android:background="#0000ff" />
<ImageView
android:id="#+id/tabIcon"
android:layout_width="#dimen/catchSize"
android:layout_height="#dimen/catchSize"
android:layout_centerInParent="true"
android:layout_marginTop="#dimen/margin"
android:src="#drawable/face" />
</RelativeLayout>
<TextView
android:id="#+id/tabUpdateTime"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_marginLeft="#dimen/margin" />
<TextView
android:id="#+id/tabText"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="#dimen/margin"
android:layout_marginRight="#dimen/margin"
android:layout_toLeftOf="#id/tabUpdateTime"
android:layout_toRightOf="#id/image"
android:text="#string/long_string" />
</RelativeLayout>

So I managed to solve the issue by using an enclosing LinearLayout instead. I have changed some of the margin stuff but I get my desired effect. :)
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:paddingLeft="#dimen/marginTop"
android:paddingRight="#dimen/marginTop"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!--Line should be "behind" (extending from top and bottom) of this imageView and should extend to the full height of the RelativeLayout after it has been rendered-->
<LinearLayout
android:orientation="vertical"
android:clipChildren="false"
android:id="#+id/frameTabIcon"
android:layout_marginRight="#dimen/margin"
android:layout_width="wrap_content"
android:layout_height="match_parent">
<View
android:id="#+id/tabTopLine"
android:layout_width="#dimen/lineThickNess"
android:layout_height="#dimen/marginTop"
android:background="#android:color/black"
android:layout_gravity="center_horizontal"/>
<ImageView
android:onClick="deletePersonOnClick"
android:id="#+id/tabIcon"
android:src="#drawable/face"
android:layout_width="#dimen/catchSize"
android:layout_height="#dimen/catchSize"/>
<View
android:id="#+id/tabBottomLine"
android:background="#android:color/black"
android:layout_gravity="center_horizontal"
android:minHeight="#dimen/marginTop"
android:layout_width="#dimen/lineThickNess"
android:layout_height="match_parent"/>
</LinearLayout>
<RelativeLayout
android:layout_marginTop="#dimen/marginTop"
android:layout_marginBottom="#dimen/marginTop"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:id="#+id/tabUpdateTime"
android:layout_marginLeft="#dimen/margin"
android:layout_alignParentRight="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
<TextView
android:id="#+id/tabText"
android:text="#string/long_string"
android:layout_marginLeft="#dimen/margin"
android:layout_marginRight="#dimen/margin"
android:layout_toLeftOf="#id/tabUpdateTime"
android:layout_width="fill_parent"
android:layout_height="wrap_content"/>
</RelativeLayout>
</LinearLayout>

ImageButton Position programmatically

I'm using XML for the layout but I need to programmatically position the ImageButton. Can anyone gives me an idea how to do it?
XML
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/mainScreenLayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<ImageView
android:id="#+id/mainScreenImage"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:scaleType="centerCrop"
android:src="#drawable/screenimage"/>
<ImageButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/titleview"
android:background="#00000000"
android:adjustViewBounds="true"
android:src="#drawable/buttonstart"/>
</FrameLayout>

First of all, wrap the ImageButton with a FrameLayout as
....
<FrameLayout
android:id="#+id/frameLayout1"
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
<ImageButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/titleview"
android:background="#00000000"
android:adjustViewBounds="true"
android:src="#drawable/buttonstart"/>
</FrameLayout>
....
This is not a must, to be a FrameLayout. Just wrap the image with some layout. But for other layouts, positioning with X and Y will vary.
Now, I can change the position of ImageButton as,
FrameLayout mFrame=(FrameLayout) findViewById(R.id.frameLayout1);
mFrame.setPadding(fromLeftX, fromTopY, fromRight, fromBottom);

i think LayoutParams will work fine
try this code
Button button = (Button)findViewById(R.id.my_button);
AbsoluteLayout.LayoutParams absParams =
(AbsoluteLayout.LayoutParams)button.getLayoutParams();
absParams.x = myNewX;
absParams.y = myNewY;
button.setLayoutParams(absParams);
and if you want to set image on it use setBackgroundResources property
button.setBackgroundResource(R.drawable.new_image);

How to show one layout on top of the other programmatically in my case?

My main layout main.xml simply contains two LinearLayouts:
The 1st LinearLayout hosts a VideoView and a Button,
The 2nd LinearLayout hosts an EditText, and this LinearLayout has set the visibility value to "GONE" (android:visibility="gone")
like below:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="fill_parent"
android:layout_width="fill_parent"
android:orientation="vertical"
>
<LinearLayout
android:id="#+id/first_ll"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
>
<VideoView
android:id="#+id/my_video"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="9"
/>
<Button
android:id="#+id/my_btn"
android:layout_width="30dip"
android:layout_height="30dip"
android:layout_gravity="right|bottom"
android:layout_weight="1"
/>
</LinearLayout>
<LinearLayout
android:id="#+id/second_ll"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:paddingTop="2dip"
android:visibility="gone"
>
<EditText
android:id="#+id/edit_text_field"
android:layout_height="40dip"
android:layout_width="fill_parent"
android:layout_weight="5"
android:layout_gravity="center_vertical"
/>
</LinearLayout>
</LinearLayout>
I successfully implemented the feature that when the Button (with id my_btn) is pressed, the 2nd LinearLayout with EditText field is shown, with the following Java code:
LinearLayout secondLL = (LinearLayout) findViewById(R.id.second_ll);
Button myBtn = (Button) findViewById(R.id.my_btn);
myBtn.setOnClickListener(new OnClickListener(){
#Override
public void onClick(View v){
int visibility = secondLL.getVisibility();
if(visibility==View.GONE)
secondLL.setVisibility(View.VISIBLE);
}
});
With the above Java code, the 2nd LinearLayout with EditText is shown like appending below the 1st LinearLayout which makes sense.
BUT, What I need is: when Button(id: my_btn) is pressed, the 2nd LinearLayout with EditText is shown on top of the 1st LinearLayout, which looks like the 2nd LinearLayout with EditText is rising from the bottom of screen, and the 2nd LinearLayout with EditText only occupy part of the screen from bottom, that's the 1st LinearLayout still visible, like the image below showed:
So, when Button(id: my_btn) is pressed how to show the 2nd LinearLayout with EditText on top of the 1st LinearLayout instead of appending 2nd LinearLayout below 1st LinearLayout programmatically?

Use a FrameLayout with two children. The two children will be overlapped. This is recommended in one of the tutorials from Android actually, it's not a hack...
Here is an example where a TextView is displayed on top of an ImageView:
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ImageView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:scaleType="center"
android:src="#drawable/golden_gate" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="20dip"
android:layout_gravity="center_horizontal|bottom"
android:padding="12dip"
android:background="#AA000000"
android:textColor="#ffffffff"
android:text="Golden Gate" />
</FrameLayout>

FrameLayout is not the better way to do this:
Use RelativeLayout instead.
You can position the elements anywhere you like.
The element that comes after, has the higher z-index than the previous one (i.e. it comes over the previous one).
Example:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent" android:layout_height="match_parent">
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/colorPrimary"
app:srcCompat="#drawable/ic_information"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="This is a text."
android:layout_centerHorizontal="true"
android:layout_alignParentBottom="true"
android:layout_margin="8dp"
android:padding="5dp"
android:textAppearance="?android:attr/textAppearanceLarge"
android:background="#A000"
android:textColor="#android:color/white"/>
</RelativeLayout>

The answer, given by Alexandru is working quite nice. As he said, it is important that this "accessor"-view is added as the last element. Here is some code which did the trick for me:
...
...
</LinearLayout>
</LinearLayout>
</FrameLayout>
</LinearLayout>
<!-- place a FrameLayout (match_parent) as the last child -->
<FrameLayout
android:id="#+id/icon_frame_container"
android:layout_width="match_parent"
android:layout_height="match_parent">
</FrameLayout>
</TabHost>
in Java:
final MaterialDialog materialDialog = (MaterialDialog) dialogInterface;
FrameLayout frameLayout = (FrameLayout) materialDialog
.findViewById(R.id.icon_frame_container);
frameLayout.setOnTouchListener(
new OnSwipeTouchListener(ShowCardActivity.this) {

Adding view to bottom of layout inside a scrollview

So my layout looks basically like this:
<ScrollView>
<RelativeLayout>
<BunchOfViews/>
<ImageView android:layout_alignParentBottom="true"/>
</RelativeLayout>
</ScrollView>
I have the ScrollView so all of the layout always is visible no matter the height of the screen. The problem is that on a very high screen, I still want my ImageView to be at the bottom. However, a child of a ScrollView don't seem to have a defined bottom. The View is placed at the top of the layout. How can I solve this problem in a neat way?

I ran into the same issue. I never could find a very pleasing solution, but here is how I did it. Maybe someone else has a better way, I hate adding layouts that don't do anything.
My hack was to add a dummy linearlayout at the bottom of the scrollview that has fill_parent to take up all the room and force the scrollview to fill the screen. Then add whatever component I want to that linearlayout.
Here is one of my layouts that does this:
<ScrollView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="1"
android:fillViewport="true" >
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_marginTop="15px" >
<!-- bunch of components here -->
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_below="#+id/spinner"
android:layout_marginTop="5px"
android:gravity="center_horizontal|bottom"
android:paddingTop="2px" >
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:paddingLeft="20px"
android:paddingRight="20px"
android:text="Delete" />
</LinearLayout>
</RelativeLayout>
</ScrollView>

I had the same issue and found this page:
http://www.curious-creature.org/2010/08/15/scrollviews-handy-trick/
Basically, you set the ScrollView's android:fillViewport to true, which will allow the child view to expand to the same height as the ScrollView itself, filling out the space. You then just need to have one of the child controls' layout_height set to fill_parent and layout_weight to 1, causing that control to "spring" to fill the empty space.
Note that if the contents of the ScrollView are already tall enough to fill the ScrollView, the android:fillViewport has no effect, so the setting only kicks in when needed.
My final XML looks like similar to this:
<ScrollView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:fillViewport="true">
<LinearLayout
android:orientation="vertical"
android:layout_height="wrap_content">
<LinearLayout
android:layout_height="fill_parent"
android:layout_weight="1">
<!-- this expands to fill the empty space if needed -->
</LinearLayout>
<!-- this sits at the bottom of the ScrollView,
getting pushed out of view if the ScrollView's
content is tall enough -->
<ImageView
android:layout_height="wrap_content"
android:src="#drawable/footer_image">
</ImageView>
</LinearLayout>
</ScrollView>

it seems that the linearlayout isn't necessary, all that is important is the fillViewPort.
you could just use
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottomParent="true">
now that you have specified the relativelayout to be at least the size of the screen.

its work for me perfectly android:fillViewport="true"

Joel Malone's answer Adding view to bottom of layout inside a scrollview does that trick. My solution is almost the same, except that I use Space widget to do the work of filling the rest height inside the parent layout. Like this:
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true"
>
<LinearLayout
android:orientation="vertical"
android:layout_height="wrap_content"
>
<android.support.v4.widget.Space
android:layout_height="match_parent"
android:layout_weight="1"
/>
<ImageView
android:layout_height="wrap_content"
android:src="#drawable/footer_image"
/>
</LinearLayout>
</ScrollView>
Attention:
fill_parent in the other answers is noted as deprecated for a long time;
Compare to an empty LinearLayout to fill the rest of parent layout, I think Space is much more appropriate(it's designed to do that job.)
Finally, don't forget that important attribute at the beginning of ScrollView: android:fillViewport="true". They together make this trick.

just put this attribute android:fillViewport="true" to your ScrolView
and you will got what you need

On your view that you want to be at the bottom use android:gravity="bottom"

From: http://code.google.com/p/k9mail/source/browse/k9mail/trunk/res/layout/account_setup_basics.xml?r=1314
This should help you:
<RelativeLayout
android:layout_marginTop="-45dip"
android:padding="0dip"
android:layout_alignParentBottom="true"
android:gravity="bottom|right"
android:background="#android:drawable/bottom_bar"
android:layout_height="fill_parent"
android:layout_width="fill_parent">
<Button
android:id="#+id/manual_setup"
android:text="#string/account_setup_basics_manual_setup_action"
android:minWidth="#dimen/button_minWidth"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_marginBottom="-4dip"
android:layout_alignParentLeft="true"
android:layout_centerVertical="false"
/>
<Button
android:id="#+id/next"
android:text="#string/next_action"
android:minWidth="#dimen/button_minWidth"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:drawableRight="#drawable/button_indicator_next"
android:layout_marginBottom="-4dip"
android:layout_alignParentRight="true"
android:layout_centerVertical="false"
/>
</RelativeLayout>

ScrollView view = new ScrollView( this );
ScrollView.LayoutParams lps = new FrameLayout.LayoutParams( FILL_PARENT, FILL_PARENT, Gravity.CENTER );
LinearLayout layout = new LinearLayout( this );
// what ever you want in the Layout
view.addView( layout, lps );

I tried alot to align the Scroll View to bottom of the screen but thats not possible according to this link.
https://newbedev.com/how-do-i-align-views-at-the-bottom-of-the-screen
The way i found was to create a view with 1dp height and aa id (lets say android:id="#+id/bottomView") at the bottom of your XML page.
now just add these attributes to your scroll view..
<ScrollView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:scrollbars="vertical"
android:fillViewport="true"
android:layout_alignBottom="#+id/bottomView"
>

Here is how you can use a ConstraintLayout to align the image view at the bottom:
<?xml version="1.0" encoding="utf-8"?>

android:fillViewport="true">
<androidx.constraintlayout.widget.ConstraintLayout

android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:id="#+id/text_view"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:text="Text 1"
app:layout_constraintBottom_toTopOf="#+id/space_view"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="parent" />
<Space

android:layout_width="match_parent"
android:layout_height="0dp"
app:layout_constraintBottom_toTopOf="#+id/image_view"
app:layout_constraintEnd_toEndOf="parent"

android:src="..."
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
