Align layout item to the right and RTL on Android

I'm trying to put three items in horizontal align using this code
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="right"
android:layout_gravity="right"
android:layout_marginTop="10dp"
android:orientation="horizontal">
<ImageView
android:layout_width="20dp"
android:layout_height="20dp"
android:layout_marginLeft="10dp"
android:src="#drawable/address"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textStyle="bold"
android:text="#string/lbl_address"/>
<TextView
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="wrap_content"
android:layout_marginLeft="5dp"
android:id="#+id/txtAddress" />
</LinearLayout>
The problem is gravity never worked, the ImageView always starts from the left and other items follows in the same order.
I have tried to reverse item orders in the code which will work on none RTL languages, but my application targets both, so it shows wrong on RTL supported devices.
Also I have tried RelativeLayout but items come over each other.
Note: All languages should start from right to left, this is my desired behavior

Add this attribute to your root LinearLayout tag:
android:layoutDirection="rtl"
This will make your view lay out as though the user had chosen a right-to-left language, regardless of what language they've actually chosen.

Try to use this code in AndroidManifest.xml
android:supportsRtl="true"
For support languages that start from right in app.

Because you use android:layout_width="0dp" android:layout_weight="1" in your code .The TextView will use the rest of space .So the left image will on the left .So you can remove android:layout_weight="1" and change the width of TextView .
You can change
<TextView
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="wrap_content"
android:layout_marginLeft="5dp"
android:id="#+id/txtAddress" />
to
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="5dp"
android:id="#+id/txtAddress" />
Note
If you want to change the location of the LinearLayout's item .You can use android:gravity="right" .
If you want to change the location of the LinearLayout ,you can use android:layout_gravity="right" .
And you code is android:layout_width="match_parent" , so the android:layout_gravity="right" has no effect .
And you can use android:layoutDirection="rtl" in your LinearLayout
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="right"
android:layout_gravity="right"
android:layout_marginTop="10dp"
android:orientation="horizontal"
android:layoutDirection="rtl"

Android - center text in OpenSansBTextView

I'm designing my constraint layout using XML.
I have an OpenSansBTextView and I need my text to be centered in it. It's centered horizontally, and not centered vertically. I don't know why. Here is my xml file. Can you see my mistake?
<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"
android:background="#color/colorAccent"
android:id="#+id/dashboard">
<com.doyousonder.android.utils.RochesterTextView
android:id="#+id/YourActivity"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintBottom_toBottomOf="parent"
android:layout_marginStart="25dp"
app:layout_constraintVertical_bias="0.34"
android:text="#string/YourActivity"
android:textColor="#color/colorPrimaryMoreDark"
android:textSize="23sp" />
<com.doyousonder.android.utils.OpenSansRTextView
android:id="#+id/YouVoted"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="#+id/YourActivity"
android:layout_marginTop="15dp"
android:layout_marginStart="20dp"
android:text="#string/YouVoted"
android:textColor="#color/colorPrimaryMoreDark"
android:textSize="15sp" />
<com.doyousonder.android.utils.OpenSansSBTextView
android:id="#+id/VoteCount"
android:layout_width="29dp"
android:layout_height="35dp"
app:layout_constraintStart_toEndOf="#+id/YouVoted"
app:layout_constraintTop_toTopOf="#+id/YouVoted"
app:layout_constraintBottom_toBottomOf="#+id/YouVoted"
android:layout_marginStart="5dp"
android:background="#drawable/more_curved_edge_button_button_primarycolor_background"
android:gravity="center"
android:text="1"
android:textAlignment="center"
android:textSize="25sp" />

You haven't provided much code to work with, i.e what is the youVoted variable. I'm assuming youvoted is your parent layout
I think you're issue comes with how you set up your constraints. Try these instead
...other layout info
app:layout_constraintBottom_toBottomOf="#+id/YouVoted"
app:layout_constraintStart_toStartOf="#+id/YouVoted"
app:layout_constraintTop_toTopOf="#+id/YouVoted"
app:layout_constraintEnd_toEndOf="#+id/YouVoted"/>
Explanation
I believe the mistake is you made is stating your textview should start at the end of your youvoted layout instead of saying it should start at the start of the youvoted layout.
change app:layout_constraintStart_toEndOf="#+id/YouVoted" to app:layout_constraintStart_toStartOf="#+id/YouVoted"
also add an end constraint.
app:layout_constraintEnd_toEndOf="#+id/YouVoted"

Move View to "next line" if it doesn't fit

So, idea in this: I have two TextViews, first can expand whatever it wants, second always 5 chars (time). Problem is in that first TextView can easily push second out of the screen.
So, what I need is something like adjustable LinearLayout, or maybe some GridLayout that will move second TextView on some sort of second line if it doesn't fit parent.
For example you can watch at message bubbles in Viber and WhatsApp. Thanks for any advise.
Update 1
Here is XML that i have now (Only message part)
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/messageBox"
android:layout_gravity="center_vertical"
android:gravity="center_vertical">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="14sp"
android:layout_gravity="center_vertical"
android:gravity="center_vertical"
android:textAppearance="#style/Base.TextAppearance.AppCompat.Medium"
android:textColor="#color/black"
android:text='#{mess.message}'/>
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center_vertical|end"
android:gravity="center_vertical|end"
android:paddingLeft="8dp"
android:textSize="12sp"
android:textAppearance="#style/Base.TextAppearance.AppCompat.Small"
android:text='#{Utils.parseMillsToHoursAndMins(mess.date)}'/>
</LinearLayout>
Update 2
So I added layout_weight to first TextView, that helped with my first problem, but now I have new one. This two TextViews are in LinearLayout which is in another LinearLayout with another TextView. Parent LinearLayout have width set to wrap_content so if top TextView will be bigger than 2 TextViews it will cause child LinearLayout to be less than it's parent, and 2nd TextView (from that 2) wouldn't be in the end of parent. But when child LinearLayout is bigger, all appears to be OK. I know it's complicated, so this is XML
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:minWidth="0dp"
android:id="#+id/contentPanel"
app:bringToFront="#{true}"
android:orientation="vertical"
android:background="#{(mess.isMine?#drawable/chat_bubble_right:#drawable/chat_bubble_left)}">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text='#{!mess.authorRole.equals("Client")?(mess.authorRole + " - " + mess.author):mess.author}'
android:textColor='#{mess.authorRole.equals("Lawyer")?#color/colorPrimary:mess.authorRole.equals("Admin")?#color/red:#color/green}'
android:textSize="12sp"
android:id="#+id/author"
android:fontFamily="sans-serif-medium"
android:textAppearance="#style/Base.TextAppearance.AppCompat.Small"/>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/messageBox">
<TextView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:textSize="14sp"
android:layout_gravity="center_vertical"
android:gravity="center_vertical"
android:layout_weight="0.7"
android:textAppearance="#style/Base.TextAppearance.AppCompat.Medium"
android:textColor="#color/black"
android:text='#{mess.message}'/>
<TextView
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:paddingLeft="8dp"
android:textSize="12sp"
android:gravity="bottom|end"
android:textAppearance="#style/Base.TextAppearance.AppCompat.Small"
app:checkFit="#{false}"
android:text='#{Utils.parseMillsToHoursAndMins(mess.date)}'/>
</LinearLayout>
</LinearLayout>

The new approach for achieving such behaviour is using ConstraintLayout with Flow. Here is an example of usage:
<androidx.constraintlayout.helper.widget.Flow
android:id="#+id/socialsButtonsFlow"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginTop="6dp"
app:flow_horizontalGap="8dp"
app:flow_verticalGap="4dp"
app:flow_wrapMode="aligned"
app:flow_horizontalStyle="spread_inside"
app:constraint_referenced_ids="vkButton,twitterButton,facebookButton,youtubeButton,instagramButton,odnoklassnikiButton,tiktokButton"
app:layout_constraintEnd_toEndOf="#id/socialsLabel"
app:layout_constraintStart_toStartOf="#+id/socialsLabel"
app:layout_constraintTop_toBottomOf="#+id/socialsLabel" />
For small screens it looks like this:

I am not sure this will help you or not but:
Use: https://github.com/ApmeM/android-flowlayout
<org.apmem.tools.layouts.FlowLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
</org.apmem.tools.layouts.FlowLayout>
Inside FlowLayout you can put your view's and it will auto move to next line if not fit.

if your textviews in linearlayout you can add weightSum method

TextView and EditText overflow

I've got a need to display and TextView (label), EditText(Input) and TextView(suffix) in a line.
The issue I have is - if the label TextView is too long it The EditText and Suffix TextView and not drawn.
Here's my code.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_gravity="center_vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TextView
android:layout_weight="0"
android:padding="5dp"
android:text="Label"
android:id="#+id/label_text_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<EditText
android:layout_weight="1"
android:id="#+id/input_edit_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColorHint="#color/dark_grey"
android:textColor="#color/black"
android:hint="text.." />
<TextView
android:padding="5dp"
android:layout_weight="0"
android:text="Suffix.."
android:background="#color/lite_grey"
android:id="#+id/suffix_text_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
So what I want is - even if the label is over 2-3 lines, for an EditText to appear followed by another TextView.
Any pointers would be appreciated.
Thanks!
Edit:
I've added some 'diagrams' so you can understand what I want to do a bit better.
The label to the EditText can be arbitrary length(2/3 lines), so whenever the label finishes I want an EditText to start (which is followed by another TextView showing a suffix..)
..
![This shows a 2 line label and TextView..]
Edit 2: Thanks for the responses guys!! I think #questioner has really understood what I want to do i.e. I want your 3 views to move to other lines so that they behave like they were one view - and as he has suggested i'll have to find a library for this!

How about this:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_gravity="center_vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:padding="5dp"
android:text="Label"
android:id="#+id/label_text_view"
android:layout_width="100dp"
android:layout_gravity="center_vertical"
android:layout_height="wrap_content"/>
<EditText
android:layout_weight="1"
android:id="#+id/input_edit_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:textColorHint="#color/dark_grey"
android:textColor="#color/black"
android:hint="text.."/>
<TextView
android:padding="5dp"
android:text="Suffix.."
android:layout_gravity="center_vertical"
android:background="#color/lite_grey"
android:id="#+id/suffix_text_view"
android:layout_width="100dp"
android:layout_height="wrap_content"/>
</LinearLayout>
If you want your 3 views to move to other lines so that they behave like they were one view - you should use external library for that.

Why not use a RelativeLayout instead of LinearLayout and then use android:layout_below="#+id/..." or android:layout_above="#+id/..." also android:layout_toRightOf="#+id/..." or android:layout_toLeftOf="#+id/..."

Set
android:layout_weight="1"
for each view so that they all occupy the same amount of horizontal space.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_gravity="center_vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:weightSum="1">
Try this or please expand a little more.

Unable to specify the alignComponent for an ImageButton

I'm trying to set my TextView to the left of an ImageButton, but I can't seems to find this option.
I was expecting to use something like android:layout_alignLeft, but this option is missing.
I've tried to google the issue, but couldn't find any relative results.
Without it my TextView overlaps the ImageButton and I want to avoid it.
UPDATE
The full xml code is too complex, but here is the important part of it:
<FrameLayout
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_alignParentLeft="true"
android:background="#color/white"
android:layout_marginLeft="8dp"
android:layout_marginTop="8dp"
android:layout_marginBottom="8dp"
android:layout_toLeftOf="#+id/frameLayoutBalanceClosed">
<ImageButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/button_edit_nickname"
android:id="#+id/card_closed_control_editNickname" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/card_closed_description_nickname"
android:layout_margin="8dp" android:layout_gravity="left"/>
</FrameLayout>

I think what you need is a RelativeLayout. You can specify your TextView to the left of your ImageView with it's specifications. Your code would look something like this:
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<TextView
android:id="#+id/text"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_toLeftOf="#+id/imagebutton1" />
<ImageButton
android:id="#+id/imagebutton1"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</RelativeLayout>
The reason FrameLayout isn't working is because it's purpose is to overlay items on top of each other, which wouldn't work at all!
If that isn't what you're looking for, you could also use a TableLayout in which items are arranged in columns.
