Switch right of TextInputLayout Android

I would like to place a Switch right of a TextInputLayout, with match_parent parameters on the TextInput and a margin.
Placing the switch to the left seems to work, however it is hidden when placing it to the right.
See the two images below:
As you can see the switch places itself wrongly.
Here is my XML code. The main layout is a CoordinatorLayout:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Social Networks"
android:textAppearance="#style/Base.TextAppearance.AppCompat.Medium"
android:textColor="#color/colorPrimary"
android:textStyle="bold" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.TextInputLayout
style="#style/Widget.MaterialComponents.TextInputLayout.OutlinedBox"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginEnd="40dp">
<android.support.design.widget.TextInputEditText
android:id="#+id/myprofile_google"
android:inputType="textEmailAddress"
android:layout_width="match_parent"
android:textColor="#color/blue_grey_800"
android:layout_height="wrap_content"
android:hint="Google +" />
</android.support.design.widget.TextInputLayout>
<Switch
android:layout_width="wrap_content"
android:layout_height="30dp"
android:layout_gravity="center_vertical"/>
</LinearLayout>
</LinearLayout>
</LinearLayout>

Change the layout_width of your TextInputLayout to 0dp, and add this attribute to it as well:
android:layout_weight="1"
What's happening right now is that your TextInputLayout has a width of match_parent. What this will do is fill the entire remaining space of the parent (this is somewhat unique to LinearLayout). When your Switch is on the left, it gets enough space for it and then the TextInputLayout takes up the rest. However, when the Switch is on the right, the TextInputLayout takes up all the space first!
Using weight instead will make sure that other components get the space they need before the weighted component gets the extra space.

You're missing two bits in your XML.
Firstly, the orientation on your linear layout containing both your input layout and switch. Secondly, use weighting to show both items as you've specified that the text input layout should match the parent (fill the view width in this case).
This layout produces your desired output:
<?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="wrap_content"
android:orientation="vertical">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Social Networks"
android:textAppearance="#style/Base.TextAppearance.AppCompat.Medium"
android:textColor="#color/colorPrimary"
android:textStyle="bold" />
<LinearLayout
android:layout_width="match_parent"
android:orientation="horizontal"
android:layout_height="match_parent">
<android.support.design.widget.TextInputLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:layout_marginEnd="40dp">
<android.support.design.widget.TextInputEditText
android:id="#+id/myprofile_google"
android:inputType="textEmailAddress"
android:layout_width="match_parent"
android:textColor="#android:color/holo_red_dark"
android:layout_height="wrap_content"
android:hint="Google +" />
</android.support.design.widget.TextInputLayout>
<Switch
android:layout_width="wrap_content"
android:layout_height="30dp"
android:layout_gravity="center_vertical"/>
</LinearLayout>
</LinearLayout>

I would suggest you use RelativeLayout instead of LinearLayout, or even better redo the whole layout in a ConstraintLayout.
The RelativeLayout implementation would probably be something like this
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.TextInputLayout
style="#style/Widget.MaterialComponents.TextInputLayout.OutlinedBox"
android:id="#+id/textInputLayout"
android:layout_toStartOf="#+id/switch"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginEnd="40dp">
<android.support.design.widget.TextInputEditText
android:id="#+id/myprofile_google"
android:inputType="textEmailAddress"
android:layout_width="match_parent"
android:textColor="#color/blue_grey_800"
android:layout_height="wrap_content"
android:hint="Google +" />
</android.support.design.widget.TextInputLayout>
<Switch
android:id="#+id/switch"
android:layout_width="wrap_content"
android:layout_height="30dp"
android:layout_alignParentEnd="true"
android:layout_gravity="center_vertical"/>
</LinearLayout>

layout_gravity isn't working as expected - just partially

I have the following layout:
<?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">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<LinearLayout
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="start"
android:text="#string/title_day"
android:textStyle="bold"
android:textSize="20sp" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="start"
android:text="Tuesday"
android:textSize="16sp" />
</LinearLayout>
<TextView
android:id="#+id/tv_fail"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="+22"
android:textSize="16sp"
android:layout_gravity="end|center_vertical" />
</LinearLayout>
</LinearLayout>
And this looks like this:
And I want the last TextView with id tv_fail to be pinned to right end of screen. I suppose that
android:layout_gravity="end|center_vertical"
should handle it, but this instruction centers TextView vertically, but doesn't move it to end. How to fix it?

I suppose that
android:layout_gravity="end|center_vertical"
should handle it, but this instruction centers TextView vertically, but doesn't move it to end.
This is due to how LinearLayout works; your understanding of layout_gravity is generally correct.
LinearLayout takes its children and lays them out in a line, and the children will all be packed towards the "start" of the LinearLayout. In other words, a horizontal LinearLayout will ignore the horizontal component of the layout_gravity attribute of a child.
There are a few ways to work around this. The one that I think works best for your scenario is to make the TextView stretch to fill all the remaining space in the LinearLayout (using layout_weight), and then have the TextView position its text at the end of its content area (using gravity).
<TextView
android:id="#+id/tv_fail"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="+22"
android:textSize="16sp"
android:layout_gravity="center_vertical"
android:gravity="end"/>

If you just want to set text inside of your last TextView to end then you should use :
android:gravity="end"
for TextView gravity use:
android:layout_gravity="center"
Difference between android:gravity & android:layout_gravity is that first one arrange content inside of any view with given gravity while second one arranges view according to given gravity.
Updated code:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:orientation="vertical">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="start"
android:text="title_day"
android:textSize="20sp"
android:textStyle="bold" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="start"
android:text="Tuesday"
android:textSize="16sp" />
</LinearLayout>
<TextView
android:id="#+id/tv_fail"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="+22"
android:textSize="16sp" />
</LinearLayout>

LinearLayout child weight not working properly

I'm trying to build the screen from picture on a tablet.
Inside fragment i have a RecyclerView with items. Each item has as root a LinearLayout. and has exactly 8 children spread horizontally with weight 1 (as in below code). The first cell on each row is a TextView and the other cells are a CustomView (a vertical LinearLayout with 2 TextViews).
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="5dp"
android:layout_marginTop="5dp"
android:orientation="horizontal" />
<TextView
android:id="#+id/item_id"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:layout_margin="2dp"
android:layout_weight="1"
android:background="#drawable/item_border"
android:drawableTop="#drawable/ic_id"
android:fontFamily="#font/cabin_bold"
android:gravity="center"
android:padding="5dp"
android:text="#string/mock"
android:textColor="#android:color/black"
android:textSize="17sp" />
<CustomView X 7 times
android:id="#+id/item_attr1"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_margin="2dp"
android:layout_weight="1"
app:titleText="Mock" />
</LinearLayout>
Given that, the row's children are not spread correctly on width, as you can see in the image. I've tried with weightSum attribute to row's root LinearLayout, but no luck. I've noticed that this issue appears (especially) when the first child of the row (which is a TextView) has a many characters.
Here is fragment's layout:
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/rootLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#F1F1F1">
<android.support.v7.widget.RecyclerView
android:id="#+id/recycler_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_margin="8dp"
app:layoutManager="LinearLayoutManager" />
<android.support.design.widget.FloatingActionButton
android:id="#+id/add_btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|end"
android:layout_margin="30dp"
android:src="#android:drawable/ic_input_add"
android:tint="#android:color/white"
app:backgroundTint="#android:color/holo_blue_dark"
app:fabSize="normal" />
<TextView
android:id="#+id/loading_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:fontFamily="#font/roboto_light"
android:text="#string/loading"
android:textSize="23sp"
android:visibility="gone" />
</android.support.design.widget.CoordinatorLayout>
Any ideas are appreciated

On the TextView:
<TextView
...
android:maxLines="1"
android:maxLength="8"
android:ellipsize="end"/>
This will prevent the TextViews from becoming too big. You can play about with the maxLength attribute to see which will fit your scenario better.

Your LinearLayout should encompass the rest of the code it's self closing now. Replace the closing tag /> with >
Close the LinearLayout below the custom view

view sliding over layout

I have relative layout. Within which I have many views like edit text, text views and so on. I do lots of animations in that. Everything was perfectly fine. But at one point, I have a requirement.
It is the password page. Create and confirm password. Two edittexts one after another. If the password doesnt meet the requirement, a plain orange view should slide up with error message "Invalid password".
So I put create and confirm password in linear layout. The linear layout will slide up, letting user type in passwords. After validation, if there is an error, the linear layout should slide down and the plain view will slide up. I kept the view invisible and when required I made it visible and wrote the code to slide up. The same code works when I just use single edit text instead of linear layout. But it is not working when using linear layout. Am I doing something wrong?
Adding code to it. The code specific to this issue starts with till the end of coding
I declared linear layout as view and NOT VIEWGROUP.
EDIT: After doing analysis, I found that the view I am trying to slide up after sliding down the layout is hidden somewhere in the view hierarchy.
view.bringToFront() helps to bring the error view to the front and slides up.
But after that the problem is, after my linear layout slide down, the error view is not sliding up straight away. Because I am using bringToFront(), it displays the view first on the whole screen (with background color as orange) and then the sliding starts.
I am not sure whether it is correct but I fixed this issue like this.
no background color has been given to the view
I used errorView.bringToFront () and errorView.setVisibility(true) in the animationEnd() of a Layout slidingdown animation listener.
I defined sliding up animation for the errorView in the same animationEnd() of layout sliding down listener
In the animationStart() of errorView sliding up animation listener, I defined the background color of the errorView. Now its working as expected.
But let me know better way of doing this.
//Declaration
View greyView, orangeView, yellowView, blueView, orangeErrorView, letsGetStartedView, welcomeBckView, passwordMasterLayout, orangePwdErrorView;
TextView welcomeText,errorTextView, letsGetStartedTextView, welcomeBckTxtView, errorPwdMsg;

orangePwdErrorView = v.findViewById(R.id.orangePasswordErrorView);
errorPwdMsg = (TextView) v.findViewById(R.id.errorPasswordMessage);

Please direct for any incorrect codings

I kept the view invisible and when required I made it visible and wrote the code to slide up.
I think you must do it in DialogFragment or custom AlertDialog that will be shown above your layout, if dont want to do this try envelop your RelativeLayout in FrameLayout and adding in it LinearLayout for example but visout your code difficult to say in what problem it is

You should consider using a library for the sliding panel, one that I've had excellent experiences with (and supports the functionality that your after) is umano's AndroidSlidingUpPanel. https://github.com/umano/AndroidSlidingUpPanel

EditText and Button side by side

I want to present in my layout an EditText and a Button side by side with a small space (margin) between them. I don't want to set a fixed size (I think that's a bad habit).
How to do that?
My Try:
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="left"
android:layout_alignParentLeft="true" />
<Button
android:id="#+id/btn_search"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_gravity="right"
android:text="Search" />
</RelativeLayout>

You're using a RelativeLayout; however, you cannot created a flexible design within that type of ViewGroup. You must use a LinearLayout.
We use android:layout_weight="1" along with the android:layout_width="0dp" to create a flexible control. Adjust the weight number for different size ratios.
Afterwards, we use android:layout_margin on both controls so the resulting weighted size of each is equal.
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<EditText
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="wrap_content"
android:layout_marginRight="8dp" />
<Button
android:id="#+id/btn_search"
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="wrap_content"
android:text="Search"
android:layout_marginLeft="8dp" />
</LinearLayout>

You can use Linear layout with horizontal orientation and add an EditText and Button in the following way
<LinearLayout
orientation="horizontal"
layoutwidth="match_parent"
layoutheight="wrap_content">
<EditText
layoutwidth="0dp"
layoutheight="wrap"
layout_weight=".8"/>
<Button
layoutwidth="0dp"
layoutheight="wrap"
layout_weight=".2"/>
</LinearLayout>
Hope this will solve your problem. Make sure to change the weights according to your needs.
Thanks

Use Linear layout to show both side by side and use 'match_parent' and 'wrap_content' appropriately.
Here's a piece of xml code
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" >
<EditText
android:id="#+id/et"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:ems="10" >
<requestFocus />
</EditText>
<Button
android:id="#+id/go"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Go!!" />
</LinearLayout>
