Relative layout views not shrinking down on smaller screen - android

I have an activity that hosts a fragment and a Button, the fragment should take the majority of the screen while the button should take a small part of the lower part of the screen.
However I can't make the Relative layout shrink down so that the button doesn't overlap over the fragment.
below is my activity layout
<?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:id="#+id/activity_registration"

android:layout_height="match_parent"
android:fitsSystemWindows="true"
android:orientation="vertical"
tools:context="com.example.activities.RegistrationActivity">
<fragment

android:layout_width="match_parent"
android:layout_height="60dp"
android:background="#color/colorPrimary"
android:text="BUTTON TEXT"
android:textColor="#android:color/holo_red_dark" />
</LinearLayout>
and below is the layout of the fragment
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"
android:layout_height="wrap_content"

below is a screenshot of how it looks


Your frangment content is too big, so you should user ScrollView inside your layout, like this.
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<RelativeLayout xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content"
tools:context="com.example.fragments.registration.GenderFragment">
<ImageView
android:id="#+id/welcome_note"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:paddingTop="#dimen/xlarge_top_margin"
android:src="#drawable/bienvenido" />
<TextView
android:id="#+id/gender_explanation"
style="#style/HeaderTitleWhite"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/welcome_note"
android:layout_centerHorizontal="true"
android:text="WELCOME TO THE APP"
android:textSize="#dimen/header_title_text_view_xtra_big_size" />
<LinearLayout
android:id="#+id/gender_avatar_holder"
android:layout_width="wrap_content"
android:layout_height="wrap_content"

android:layout_centerHorizontal="true"
android:layout_marginTop="#dimen/medium_top_margin"

relative layout gravity center not aligning correctly

I'm trying to center the chilldren of my relative layout in the center of my screen but it's acting like it's aligned to the top of the parent and I can't figure out why.
my .XML:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"

android:gravity="center"
android:background="#f70909">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/imageView2"
android:adjustViewBounds="true"
android:src="#drawable/dice"/>

android:indeterminate="true"
android:layout_below="#+id/btnSplash" />
</RelativeLayout>
I've tried making the parent a relativelayout without success and it won't align to the bottom either. Initially I thought the layout wasn't filling the whole screen but since its height and width are match_parent I don't think that's the problem. in android studio it is displaying correctly though so I must be missing something small.
I also tried using the gravity and layoutgravity parameters and a combination of the two but without success
Edit: I need the views to stay in the same formation relative to each other but centered in the screen vertically.
Edit 2:I set the background of the RelativeLayout to red and got this: So the relativelayout isn't filling my screen.
Edit 3:
Edit 4:

try this:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"

Try something like this.
<?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:id="#+id/imageView2"
android:adjustViewBounds="true"
android:layout_centerInParent="true"/>
<LinearLayout
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:gravity="center"
android:layout_centerInParent="true">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"

<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"

<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/editPasswordSplash"

android:gravity="center" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Login"

<ProgressBar
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/prgSplash"
style="#android:style/Widget.DeviceDefault.ProgressBar.Large"
android:indeterminate="true" />
</LinearLayout>
</RelativeLayout>
UPDATE:
If setting the xml in an AlertDialog, it's possible that there is a space allotted at the bottom. I google and found this alert_dialog.xml for reference. It seems that there is a buttonPanel at the bottom with a minimum height of 54dip.
<LinearLayout android:id="#+id/buttonPanel"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:minHeight="54dip"

android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:paddingTop="4dip"
android:paddingStart="2dip"
android:paddingEnd="2dip"
android:measureWithLargestChild="true">
<LinearLayout android:id="#+id/leftSpacer"
android:layout_weight="0.25"
android:layout_width="0dip"

Thanks to ank I was able to figure out that the reason why the RelativeLayout didn't fill my screen is that I used it in an alertDialog. So RelativeLayouts parent isn't the screen but the alertDialog. Since an alertDialog wraps its content it doesn't fill the entire screen.

Picture not aligning top?

So in my program i have a layout implemented in which i want the image to alignTop of the parent. I used to exact same layout code for another activity (with minor changes) and it works perfectly but when using it in this activity it does not. My image still aligns to the center fo the view. Here is the layout xml

I've tried using,
android:fillViewport="true"
but of no help.

A ScrollView is a FrameLayout, meaning you should place one child in it containing the entire contents to scroll; this child may itself be a layout manager with a complex hierarchy of objects.
So here you have to take LinearLayout or RelativeLayout and then you have to put different hierarchy of component.
Android : buttons not visible in scrollview
here i have given answer of Some problem so you can follow this for solve your problem with clearing your concept.

Try like this ,Scrolling will work till End
<RelativeLayout 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">
<ScrollView
android:id="#+id/scrollView1"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/app_icon"
android:layout_marginTop="20dp"
android:layout_gravity="center_horizontal"/>
<TextView
android:id="#+id/textView_app_version"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="20dp"
android:layout_gravity="center"/>
<TextView
android:id="#+id/textView_content"
android:layout_width="match_parent"
android:layout_marginTop="15dp"
android:layout_height="386dp"
android:gravity="center"/>
</LinearLayout>
</ScrollView>
</Relativelayout>

If ScrollView fits to your device screen it would not be scrollable, so make sure content inside ScrollView takes space larger than your screen size.

systematix Try this,here you getting scroll.

Imagebuttons won't align on the right next to eachother

I'm dynamically injecting rows in a container of a fragment.
But I just can't seem to get the three image buttons aligned to the right, next to each other.
Anyone an idea?
Fragment layout:

How the row looks on my phone (the same on a API 19 AVD):
How Android Studio, when designing, shows the row:

try this
<?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"

style="#style/switch_row_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:text="Switch name" />
<TextView
android:id="#+id/switch_lastSeen"
style="#style/switch_row_lastSeen"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/switch_name"
android:text="#string/last_seen" />

How to center two views within a relative layout?

The task is simple: there are two buttons and a TextView above them. All the widgets shoud be centered within the relative layout. The only one idea I have is create the third widget View and use it as a center axis for the buttons. Any ideas? A redundant layout isn't a good solution.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<TextView
android:id="#+id/tv_progress"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:text="#string/app_name" />
<View
android:id="#+id/view_axis"
android:layout_width="1dp"
android:layout_height="1dp"
android:layout_below="#id/tv_progress"
android:layout_centerInParent="true" />
<Button
android:id="#+id/button_start"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/tv_progress"
android:layout_toLeftOf="#id/view_axis"
android:text="#string/start" />
<Button
android:id="#+id/button_stop"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/tv_progress"
android:layout_toRightOf="#id/view_axis"
android:text="#string/stop" />
</RelativeLayout>

If I understand what you want correctly, you can put the Buttons in a LinearLayout and center that
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<TextView
android:id="#+id/tv_progress"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:text="#string/app_name" />
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_below="#id/tv_progress">
<Button
android:id="#+id/button_start"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/start" />
<Button
android:id="#+id/button_stop"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/stop" />
</LinearLayout>
I'm not sure if that's what you meant by a "redundant layout" but doing this is fine if it gives you what you want.

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<Spinner
android:id="#+id/sp_rooms"
android:layout_toLeftOf="#id/space"
android:layout_centerVertical="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<Space
android:id="#+id/space"
android:layout_centerInParent="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<Button
android:id="#+id/btn_registration"
android:layout_centerVertical="true"
android:layout_toRightOf="#id/space"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</RelativeLayout>

This will vertically and horizontally center the whole block consisting of the textview + buttons
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_centerInParent="true">
<TextView
android:id="#+id/tv_progress"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/app_name" />
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<Button
android:id="#+id/button_start"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/start" />
<Button
android:id="#+id/button_stop"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/stop" />
</LinearLayout>
</LinearLayout>
</RelativeLayout>
