Android Studio layer below each other while orientation is horizontal - android

doing this layer work and can't figure out how to put layers below ones I made when the android orientation is horizontal, it keeps pushing my layer to the outsidie I have a pics what I have done and how it has to look, if you have any ideas would be nice to hear, thank you in advance.How it has to look
and What I have done

If you are using

app:layout_constraintTop_toTopOf
app:layout_constraintTop_toStartOf
app:layout_constraintTop_toRightOf

it should look like this


Use 2 seperate LinearLayout one below other in root.
One for horigontal views. Second for vertical views.
And use weight_sum property in LinearLayout, along with weight property in child views to distribute child views eqally.

Sticky view with vertical scrolling using constraint layout or any other way in android

The red portion is wrap content and can be expanded, depends on how much data it contains. The green part/view always sticks between red and white. The screen is vertically scrollable.
THE attached XML code having scrollview and layout weight but it divides the screen into two parts from the middle, which is not as per the requirement.
Please suggest how to achieve this.

You can use constraint layout inside a nestedScrollView like this :
<?xml version="1.0" encoding="utf-8"?>
<androidx.core.widget.NestedScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

android:layout_height="match_parent">
<LinearLayout
android:id="#+id/redPortion"
android:layout_width="match_parent"
android:layout_height="wrap_content" //Red Portion
android:orientation="vertical"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<com.google.android.material.card.MaterialCardView
android:id="#+id/green_sticky_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:layout_constraintTop_toBottomOf="#+id/redPortion" //Green Sticky View
app:layout_constraintBottom_toBottomOf="#+id/redPortion"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
/>
<LinearLayout
android:id="#+id/whitePortion"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" //White Portion
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="#+id/redPortion"
/>
</androidx.constraintlayout.widget.ConstraintLayout>
</androidx.core.widget.NestedScrollView>
Use any layout you want for your red, white and green views.
I hope This helps.

Place buttons one below the other

I have 2 buttons but both of them are on the same line, so one of them is not clickable and not even readable.
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout 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:background="#343535"
tools:context=".fragments.GeneralFragment">
<Button
android:id="#+id/hello"
android:layout_width="match_parent"
android:layout_height="60dp"
android:gravity="center_vertical"
android:text="#string/hello"
/>
<Button
android:id="#+id/observed"
android:layout_width="match_parent"
android:layout_height="60dp"
android:drawableBottom=""
android:gravity="center_vertical"
android:text="#string/observed" />
</FrameLayout>
How can I display them one below the other?

You are currently using FrameLayout, which should only be used when you have only one view under the FrameLayout.
To fulfill your requirements, you should use LinearLayout with vertical orientation.

You have to use RelativeLayout or LinearLayout
<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"
android:background="#343535"
tools:context=".fragments.GeneralFragment">
<Button
android:id="#+id/hello"
android:layout_width="match_parent"
android:layout_height="60dp"
android:gravity="center_vertical"
android:text="#string/hello"
/>
<Button
android:id="#+id/observed"
android:layout_below="#+id/hello" //Added Layout below
android:layout_width="match_parent"
android:layout_height="60dp"
android:drawableBottom=""
android:gravity="center_vertical"
android:text="#string/observed" />
</RelativeLayout>
Using LinearLayout you can set android:orientation="vertical" to get element adjusted to below automatically

The most reliable layout is the constraint layout you can work with just like that
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout
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">
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button1"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="10dp"
android:text="Button2"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="#id/button1" />
</androidx.constraintlayout.widget.ConstraintLayout>

The easiest way is just using LinearLayout:
<?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="wrap_content"
android:background="#343535"
android:orientation="vertical"
tools:context=".fragments.GeneralFragment">
<Button
android:id="#+id/hello"
android:layout_width="match_parent"
android:layout_height="60dp"
android:gravity="center_vertical"
android:text="#string/hello" />
<Button
android:id="#+id/observed"
android:layout_width="match_parent"
android:layout_height="60dp"
android:drawableBottom=""
android:gravity="center_vertical"
android:text="#string/observed" />
</LinearLayout>

How to center a progressbar in screen

The progress bar is appearing on the left of the screen. I would want it centered, like in the example.
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:gravity="center"
android:background="#drawable/semi_circle"
android:layout_width="match_parent"
android:layout_height="match_parent">
<RelativeLayout
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:layout_marginTop="50dp"
android:layout_gravity="center_horizontal"
android:id="#+id/relative">
<ProgressBar
android:id="#+id/progress_bar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:visibility="visible" />
<LinearLayout android:layout_width="match_parent"
android:id="#+id/lilPolicy"
android:layout_height="match_parent"
android:layout_marginBottom="20dp">
</LinearLayout>

You should get the ProgressBar outside the ScrollView, because logically you can know the height of the ScrollView at Runtime, so you can't figure out where the ProgressBar will place until running your app.
So, get out the ProgressBar from the ScrollView, create another root layout, wrap both ProgressBar & ScrollView in it; I picked RelativeLayout as the root, you can decide another layout manager if you wish.
layout_centerInParent attribute is used to center a view within a RelativeLayout
<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"
android:background="#drawable/semi_circle"
android:gravity="center">
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<RelativeLayout
android:id="#+id/relative"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:layout_marginTop="50dp">
<LinearLayout
android:id="#+id/lilPolicy"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginBottom="20dp">
</LinearLayout>
</RelativeLayout>
</ScrollView>
<ProgressBar
android:id="#+id/progress_bar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:visibility="visible" />
</RelativeLayout>
Note: I don't know what you're going to accomplish, so I left android:background="#drawable/semi_circle in the root layout

Inside your scrollView
Using RelativeLayout:
<?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">
<ProgressBar
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true" />
</RelativeLayout>
Using ConstraintLayout:
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout 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">
<ProgressBar
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
</androidx.constraintlayout.widget.ConstraintLayout>

Add ConstraintLayout to your project, Build a Responsive UI with ConstraintLayout
You can easily implement it.
The way I would have done it is:
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout 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">
<ProgressBar
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<ScrollView
android:layout_width="0dp"
android:layout_height="0dp"
android:fillViewport="true"
android:orientation="vertical"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent">
<android.support.constraint.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:id="#+id/item_1"
android:layout_width="match_parent"
android:layout_height="80dp"
android:layout_marginRight="10dp"
android:layout_marginLeft="10dp"
android:layout_above="#id/item_2"
android:background="#0000FF"
android:layout_marginTop="10dp"
android:orientation="horizontal"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<LinearLayout
android:id="#+id/item_2"
android:layout_width="match_parent"
android:layout_height="80dp"
android:layout_marginRight="10dp"
android:layout_marginLeft="10dp"
android:layout_marginTop="10dp"
android:layout_below="#id/item_1"
android:background="#FF0000"
android:orientation="horizontal"
app:layout_constraintTop_toBottomOf="#id/item_1" />
<LinearLayout
android:id="#+id/item_3"
android:layout_marginTop="10dp"
android:layout_width="match_parent"
android:layout_height="80dp"
android:layout_marginRight="10dp"
android:layout_marginLeft="10dp"
android:layout_below="#id/item_2"
android:background="#FFFF00"
android:orientation="horizontal"
app:layout_constraintTop_toBottomOf="#id/item_2" />
</android.support.constraint.ConstraintLayout>
>
</ScrollView>
</android.support.constraint.ConstraintLayout>

If you have used relative layout as a parent layout . so we need to add this attribute android:layout_centerInParent="true" to align view in parent center. and scroll view by default remove extra spacing in view . add android:fillViewport="true" to make scroll view match parent
Try this code
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:gravity="center"
android:background="#000"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true">
<RelativeLayout
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:layout_marginTop="50dp"
android:layout_gravity="center_horizontal"
android:id="#+id/relative">
<ProgressBar
android:id="#+id/progress_bar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:visibility="visible" />
<LinearLayout android:layout_width="match_parent"
android:id="#+id/lilPolicy"
android:layout_height="match_parent"
android:layout_marginBottom="20dp"
android:orientation="horizontal">
</LinearLayout>
</RelativeLayout>
</ScrollView>

use android:layout_centerInParent="true" as you are using RelativeLayout.

scrollbar in constraint layout not working

follow this layer it might work.put appbarlayout inside ConstraintLayout layout
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<!--add your scrollview or nestedscrollview here-->
</LinearLayout>
</android.support.design.widget.AppBarLayout>

Your ScrollView height is fixed to 611dp.
If you use a fixed size, then the content should be greater than 611dp to be able to scroll.
You should use
<ScrollView
android:id="#+id/scrollView2"
android:layout_width="match_parent"
android:layout_height="match_parent"

MPAndroid chart in ConstraintLayout with additional widgets (they are not visible)

I am trying to add PieChart from MPAndroidChart and seekBar under it.
But still no luck, chart is visible, but other content is noT visible, despite it visible when I open design tab during xml configuration.
I already have tried to set a barrier and with groups with weights but still.
Could please anyone give any advice how to properly align chart to be able to see other widgets on view.
Here is my xml example:

ANSWER
The first and correct version of answer from Ashish Kudale is: Use LinearLayout with weight:
<LinearLayout
android:id="#+id/chartContent"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<com.github.mikephil.charting.charts.PieChart
android:id="#+id/pieChart"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="4"/>
<android.support.v7.widget.AppCompatSeekBar
android:id="#+id/seekBar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"/>
</LinearLayout>

Use LinearLayout Insted of ConstraintLayout.
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:id="#+id/linearLayout3"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<com.github.mikephil.charting.charts.PieChart
android:id="#+id/pieChart"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1" />
<LinearLayout
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="match_parent">
<SeekBar
android:id="#+id/seekBar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="text" />
</LinearLayout>
</LinearLayout>
What it does is places all items in the screen and remaining place is occupied by item which has android:layout_weight="1"
