I want a help for design a screen.. I want to make a details screen, with a picture and a text (scrollabe).. But when i test, the text doesnt fill all the space...Its puts a empty space at the bottom of the text... How can i fill all the layout with the text?
<?xml version="1.0" encoding="utf-8"?>

</ScrollView>
</LinearLayout>
</android.widget.RelativeLayout>
and the screen:
You need to change to "match_parent" in your first LinearLayout´s height and widht parameters to fill all the screen, cause the parent in this case is your phone' screen, but if you define values in dp as shown in your code (495dp) then it´ll fill just that dimensions, and the screen dimensions change with every phone and his own screen size, that´s why it works in some little screen devices, and with bigger screens probably wont do it, the best solution to make it work with every screen size is changing your code like this:
<?xml version="1.0" encoding="utf-8"?>
<android.widget.RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.rs.app.paginas.antena_detalhe">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:weightSum="1"
tools:layout_editor_absoluteX="8dp"
tools:layout_editor_absoluteY="8dp">
...
Hope it helps,
You should change from:
<?xml version="1.0" encoding="utf-8"?>

In your layout you have defined fixed dimensions for your linear layout which contains your scroll view and other widgets. I would suggest changing your root layout to Linear Layout with maximum width and height :
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:weightSum="1"
tools:layout_editor_absoluteX="8dp"
tools:layout_editor_absoluteY="8dp"
tools:context="com.example.rs.app.paginas.antena_detalhe">
And remove the child linear layout.
Reason you were getting extra space was because of fixed height,which may be not present on phone with lesser height.

Here you can see that there is a background and above it there is a white layer on which contain are given. screenshot is of a website but i want to give that effect on my app. any help will be of great use.
You can do it like this:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".activity.MainActivity">
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:src="#drawable/yourBackgroudImage"/>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:bacground="#color/white"
android:layout_margin="20dp">
<!--your code inside white backgroud layout goes here-->
</LinearLayout>
</LinearLayout>
Just use a RelativeLayout which helps you to stack your views above each other,then provide a margin to the top layout
<?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="wrap_content">
<ImageView
android:src="#drawable/backgroundimage"
android:scaleType="centerCrop"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<LinearLayout
android:layout_margin="20dp"
android:background="#ffffff"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!--Add Data here as required-->
</LinearLayout>
</RelativeLayout>
I have 2 vertical linear layouts in one horizontal parent linear layout like this:

android:layout_height="match_parent"
android:layout_weight="0.1"
android:orientation="vertical"
android:id="#+id/imagebtn_layout">
</LinearLayout>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="0.9"
android:layout_marginRight="1dp"
android:orientation="vertical"
android:id="#+id/button_layout">
</LinearLayout>
</LinearLayout>
</LinearLayout>
Now I add 2 buttons programmatically to their views:
One into imagebtn_layout and the other one into button_layout with the parameters: (LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT). The text of the button is set to 20.6f. The picture for the image button has 44x44 pixels.
The result looks fine on my Pixel 2 (1920x1080), but horrible e.g. on 2560x1440:
I'm not sure what's wrong. The result should be that the ImageButton and the normal button are on all screens at the same line.
Edit: Solved after using the solution from gmetax and setting android:layout_height in the parent view to "wrap_content" and adapting font size of text button.
you have to specify the width of the image that you know and then let the other fill the empty space.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

I have a problem with this Recycle View on this layout, it don't take the complete height of your father container.
I used the weight parameters, but that is not the problem i think.
Check the code and Print screen.
Thanks in advance.

Layout
My activity's main layout is a LinearLayout. It has two children as an example. A RelativeLayout and a Button. The width and height of RelativeLayout are set to match_parent and the Button, match_parent and wrap_content. Unfortunately, RelativeLayout pushes the button below until it is not visible.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 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"
android:orientation="vertical">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent" />
</RelativeLayout>
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
Why is this happening? I tried a tweak for the RelativeLayout which is changing the height to 0dp and weight to 1. It does make the Button visible but I am not sure if this is advisable as I only changed the height and weight of RelativeLayout.
Try this
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:fillViewport="true"
android:layout_height="match_parent">
<LinearLayout 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"
android:orientation="vertical">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent" />
</RelativeLayout>
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
</ScrollView>
OR
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:fillViewport="true"
android:layout_height="match_parent">
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<RelativeLayout
android:layout_width="match_parent"
android:layout_above="#+id/btn"
android:layout_height="match_parent">
<ImageView
android:layout_width="match_parent"
android:src="#drawable/disha"
android:layout_height="match_parent" />
</RelativeLayout>
<Button
android:id="#+id/btn"
android:layout_width="match_parent"
android:layout_margin="10dp"
android:text="NIlu"
android:layout_alignParentBottom="true"
android:layout_height="wrap_content" />
</RelativeLayout>
</ScrollView>
LinearLayout is either Vertical or Horizontal. Your first child which is RelativeLayout is matchParent then it will cover whole Outer layout .
Solution can be multiple its depends upon where exactly you want to place your Button . One way is .
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<RelativeLayout
android:layout_width="match_parent"
android:layout_above="#+id/btn"
android:layout_height="match_parent">
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent" />
</RelativeLayout>
<Button
android:id="#+id/btn"
android:layout_width="match_parent"
android:layout_margin="10dp"
android:layout_alignParentBottom="true"
android:layout_height="wrap_content" />
</RelativeLayout>
Change your Code Like
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 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"
android:orientation="vertical">
<RelativeLayout
android:layout_weight="1"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent" />
</RelativeLayout>
<Button
android:text="#string/app_name"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
Worked Foe me..
you should Give android:layout_weight="1" to relative Layout
//try this
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 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"
android:orientation="vertical">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ImageView
android:layout_width="match_parent"
android:layout_height="200dp" />
</RelativeLayout>
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
this seems to work just fine.
I tried a tweak for the RelativeLayout which is changing the height to
0dp and weight to 1
the code look 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="match_parent"
android:layout_height="match_parent">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
>
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
</RelativeLayout>
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
/>
</LinearLayout>
In your layout, RelativeLayout is the first child of your LinearLayout. Since, you have set the height and width to match_parent it takes up all available space pushing the button out of the view.
When you set the RelativeLayout height to 0dp and weight to 1, LinearLayout first lays out all children based on the dimensions specified, and then distributes the remaining space based on the weight. In this case, the relative layout is 0dp, so it takes no space in first pass, and the button takes up space based on its onMeasure (lets say 100dp). The remaining space is now given to RelativeLayout because its weight is set to 1. Refer to the LinearLayout documentation for more details here.
You should consider using a RelativeLayout/ConstraintLayout as your root element.
i want to divide my screen in half vertically, and do a different color in each half,
i was trying to use this solution mentioned in here>
Android: 2 relative layout divided in half screen
but it doesn't work for me.
this is my layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:baselineAligned="false"
android:orientation="horizontal"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
tools:context=".activities.alignmentActivities.Add_New_Project_Activity"
tools:showIn="#layout/app_bar_add__new__project_">
<RelativeLayout
android:layout_width="0dp"
android:layout_height="wrap_content"
android:background="#f00000"
android:layout_weight="1">
</RelativeLayout>
<RelativeLayout
android:layout_width="0dp"
android:background="#00b0f0"
android:layout_height="wrap_content"
android:layout_weight="1">
</RelativeLayout>
</LinearLayout>
how can i achieve the desired effect of 2 layouts each takes half the screen vertical \ what am i doing wrong then the example mentioned in the link ?
You may Try to use this :
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 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"
android:weightSum="2"
android:orientation="horizontal"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
<RelativeLayout
android:layout_width="0dp"
android:layout_height="match_parent"
android:background="#f00000"
android:layout_weight="1">
</RelativeLayout>
<RelativeLayout
android:layout_width="0dp"
android:background="#00b0f0"
android:layout_height="match_parent"
android:layout_weight="1">
</RelativeLayout>
Output :
Add the following attribute in your LinearLayout
android:weightSum="2"
After adding this your code will work.
WeightSum attribute defines the total number of equal divisions you want it to be divided.If you want it to be divided into 3 parts, change its value as 3.
<?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">
<RelativeLayout
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:background="#color/red">
</RelativeLayout>
<RelativeLayout
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:background="#color/white">
</RelativeLayout>
</LinearLayout>

If you want to divide screen vertically than you need to use android:orientation="vertical" and in child layout use android:layout_width="match_parent"
check below xml,
<?xml version="1.0" encoding="utf-8"?>

android:orientation="vertical"
android:weightSum="2"
app:layout_behavior="#string/appbar_scrolling_view_behavior" >
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="0dp"
