ImageView not showing in linear layout that is inside a scrollview

ImageView not showing in linear layout that is inside a scrollview - android

I am trying to have two scrollable items inside my scrollview so I put a linear layout into the scroll view and inside the linear layout I put an imageview and a textview. The textview shows up but the imageview does not. What is the issue here?
<?xml version="1.0" encoding="utf-8"?>

android:layout_height="match_parent"

<TextView
android:id="#+id/name_text"
style="#style/NameStyle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/name"
android:textAlignment="center" />
<ImageView

android:layout_width="match_parent"
android:layout_height="wrap_content"
android:lineSpacingMultiplier="1.2"
android:text="#string/bio" />
</LinearLayout>
</ScrollView>
</LinearLayout>

Solved: I was missing this line: app:srcCompat="#mipmap/image"
I feel dumb

Align Recycler View above linear layout

The list of things expected in the outout
1.a linear layout to the buttom of the activity as shown in the expected image
2.a recycler view above the linear layout to achieve the scrolling funtionality as shown in the expected image
The problem can be solved if I give the height to the recycler view.But in this case the layout won't be responsive to the samller sized screens
How can I achieve it?

If you wish to tell your RecyclerView to fill the left over space of your LinearLayout you have to use the following layout_height and layout_weight on your RecyclerView:
<androidx.recyclerview.widget.RecyclerView
android:id="#+id/product_recycler"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:padding="0dp" />

How to make Android xml Linerlayout at the bottom of the activity in Android Studio?

How do I make LinearLayout in Android Studio at the bottom of the page. The result from the code below
I want the highlighted darken layout to be at the bottom of the page.
<?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"

<Button
android:id="#+id/taptoscan"
android:layout_marginTop="40dp"
android:layout_marginBottom="10dp"
android:layout_width="120dp"
android:layout_height="120dp"
android:background="#drawable/barcode"
android:layout_gravity="center"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Tap to Scan"
android:fontFamily="#font/antic"
android:layout_gravity="center"
android:textSize="18sp"/>
<!--here is the layout i want to put at the bottom of the page-->
<LinearLayout
android:layout_width="match_parent"
android:layout_height="40dp"
android:background="#color/colorPrimaryDark"
android:orientation="horizontal"
android:layout_alignParentBottom="true"
android:layout_gravity="bottom"
android:gravity="bottom">
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content">
</RelativeLayout>
</LinearLayout>
In the above code I tried the below and did not worked.
android:layout_alignParentBottom="true"
android:layout_gravity="bottom"
android:gravity="bottom"

You can use RelativeLayout at the outside. Something like this, and then ADD new one LinearLayout after that.
<?xml version="1.0" encoding="utf-8"?>
<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="#ffffff"
android:orientation="vertical"
tools:context=".MainPage">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<Button
android:id="#+id/taptoscan"
android:layout_width="120dp"
android:layout_height="120dp"
android:layout_gravity="center"
android:layout_marginTop="40dp"
android:layout_marginBottom="10dp"
android:background="#drawable/barcode" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:fontFamily="#font/antic"
android:text="Tap to Scan"
android:textSize="18sp" />
</LinearLayout>
<!--here is the layout i want to put at the bottom of the page-->
<LinearLayout
android:layout_width="match_parent"
android:layout_height="40dp"
android:layout_alignParentBottom="true"
android:layout_gravity="bottom"
android:background="#color/colorPrimaryDark"
android:gravity="bottom"
android:orientation="horizontal">
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
</RelativeLayout>

Use Frame Layout as base layout to do it in the best way, it's gonna work definitely
Just use layout_gravity="bottom" in the LinearLayout which you want at bottom and
Just like this :
<?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="#ffffff"
android:orientation="vertical"
tools:context=".MainPage">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<Button
android:id="#+id/taptoscan"
android:layout_width="120dp"
android:layout_height="120dp"
android:layout_gravity="center"
android:layout_marginTop="40dp"
android:layout_marginBottom="10dp"
android:background="#drawable/barcode" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:fontFamily="#font/antic"
android:text="Tap to Scan"
android:textSize="18sp" />
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="40dp"
android:layout_gravity="bottom"
android:background="#color/colorPrimaryDark"
android:orientation="horizontal">
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
</FrameLayout>

The approach below would help you achieve your design specifications with zero overlappings. Basically, there are four key steps:
Change your root layout to a RelativeLayout.
Inside the RelativeLayout, add a LinearLayout that would contain your Button and your TextView.
Inside the same RelativeLayout, add the LinearLayout that you intend to pin to the bottom of the screen.
Make sure yoU set the first LinearLayout on top of the second by using the android:layout_above="" attribute.
Now, here's the code:
<?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"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainPage">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:background="#ffffff"
android:layout_above="#+id/bottomView">
<Button
android:id="#+id/taptoscan"
android:layout_marginTop="40dp"
android:layout_marginBottom="10dp"
android:layout_width="120dp"
android:layout_height="120dp"
android:background="#drawable/barcode"
android:layout_gravity="center"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Tap to Scan"
android:fontFamily="#font/antic"
android:layout_gravity="center"
android:textSize="18sp"/>
</LinearLayout>
<!--here is the layout i want to put at the bottom of the page-->
<LinearLayout
android:layout_width="match_parent"
android:layout_height="40dp"
android:id="#+id/bottomView"
android:background="#color/colorPrimaryDark"
android:orientation="horizontal"
android:layout_alignParentBottom="true"
android:layout_gravity="bottom"
android:gravity="bottom">
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content">
</RelativeLayout>
</LinearLayout>
</RelativeLayout>
I hope this helps.

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.

android TextView: How to avoid line breaks?

I'm trying to figure out how to avoid line breaks within a TextView.
If the lines are too long for the width of TextView, a horizontal scroll bar should appear. Everything I tryed with android:scrollbars (and so on) failed, there are always line breaks. This is my layout code:
<?xml version="1.0" encoding="utf-8"?>
<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"
tools:context="de.zpit2u.maingate.MainGate_Logs">
<TextView
android:id="#+id/tvTitle_Logs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textSize="20sp"
android:text="#string/app_logs" />
<android.support.v4.widget.SwipeRefreshLayout
android:id="#+id/historyRefresh"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/tvTitle_Logs" >
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:padding="10dp"
android:fillViewport="false" >
<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"
tools:context="de.zpit2u.maingate.MainGate_Logs">
<TextView
android:id="#+id/tvTitle_Logs_Clients"
android:layout_marginTop="20dp"
android:layout_marginStart="20dp"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textSize="18sp"
android:text="#string/logs_clients" />
<TextView
android:id="#+id/tvText_Logs_Clients"
android:layout_below="#+id/tvTitle_Logs_Clients"
android:layout_marginTop="10dp"
android:layout_width="match_parent"
android:layout_height="10dp"
android:textSize="8sp"
android:fontFamily="monospace" />
<ProgressBar
android:id="#+id/progressBarLogs"
style="?android:attr/progressBarStyleSmall"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerInParent="true" />
</RelativeLayout>
</ScrollView>
</android.support.v4.widget.SwipeRefreshLayout>
Second TextView (tvText_Logs_Clients) within the RelativeLayout should be horizontally scrollable.

the way to make textview scroll horizontally.
<HorizontalScrollView android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView android:layout_width="40dp"
android:layout_height="wrap_content"
android:scrollHorizontally="true"
android:text="Horizontal scroll view will work now"/>
</HorizontalScrollView>

CardView Layouts overlapping

I have two cards views, I want to place one above the other but the end result is that they are placed on top of each other:
This is the XML code:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<android.support.v7.widget.CardView
android:id="#+id/entryTypeCardView"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<Spinner
android:id="#+id/entryChoiceSpinner"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="10dp" />
</android.support.v7.widget.CardView>
</RelativeLayout>
<RelativeLayout
android:layout_width="match_parent"
android:id="#+id/currencySpinnerLayout"
android:orientation="vertical"
android:layout_height="wrap_content">
<android.support.v7.widget.CardView
android:id="#+id/currencyTypeCardView"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<Spinner
android:id="#+id/currencyChoiceSpinner"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="10dp" />
</android.support.v7.widget.CardView>
</RelativeLayout>
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="match_parent">
<AutoCompleteTextView
android:id="#+id/personNameTextField"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
...
What am I doing wrong?

Assign some id to first RelativeLayout
<RelativeLayout
android:id="#+id/first_layout"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
and then used
android:layout_below="#+id/first_layout"
to second layout.
