How to reduce material.switchmaterial.SwitchMaterial end margin in android?

I've used "com.google.android.material.switchmaterial.SwitchMaterial" in that left margin having some space. How to reduce that?
I've need align straight of the everyone text. I'm not add end margin or padding of the switch, Parent layout margin only I've set. Below my XML code and styles. Please provide your suggestion to reduce that margin, Thanks.
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_margin="10dp">
<RelativeLayout

android:layout_height="wrap_content"
android:layout_marginTop="30dp">

In your relativeLayout/topRelativeLayout, You added margin. Which means you want to margin from every side. That's why It's happening
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_margin="10dp">
remove the android:layout_margin="10dp". Add margin_top, margin_right what you wanna do.

You should give wrap content for switch width , or make it inside a new Relative layout

if your end margin is showing after removing from
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_margin="10dp">
then
<com.google.android.material.switchmaterial.SwitchMaterial
android:id="#+id/save_switch"
style="#style/SwitchButtonStyle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/who_can"
android:checked="true"
android:text="#string/save_gallery"
android:textSize="#dimen/text_small"
app:trackTint="#color/colorSecondaryText" />
change in SwitchButtonStyle it gives you some default value we are happy if you share whole file

you can see that default drawables (thumb and track) from a theme have this paddings
so the way is try to use your custom drawables (but this may affect their appearance)
app:track="#drawable/track"
android:thumb="#drawable/thumb"

UI bug android - screen not matched on top edge

I'm working on this app and I have implemented a photo slider through ViewPager. There is an imported circle page slider indicator, a project on github. It looks like this: (Sorry for the blured text, I'm not able to share the content until release. The app will be free)
My problem is that thin blue line on the top of the screen. Blue color comes from the background and it is set in the root layout of the activity. No matter what I do to the any of the layouts (changing margins or padding to negative values) this line remains there.
So I figured that it has to do with the chosen theme for the screen. Theme is set to a custom theme which has Theme.NoTitleBar as it's parent. The code is below:
This is the style file. Taken from http://viewpagerindicator.com/ by Jake Wharton.
<style name="Theme.PageIndicatorDefaults" parent="android:Theme.NoTitleBar">
<!--<item name="vpiIconPageIndicatorStyle">#style/Widget.IconPageIndicator</item>
<item name="vpiTabPageIndicatorStyle">#style/Widget.TabPageIndicator</item>-->
<item name="vpiCirclePageIndicatorStyle">#style/Widget.CirclePageIndicator</item>
</style>
This is my activity layout:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/accountRoot"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/gradientbg"
android:orientation="vertical"
android:gravity="bottom">
<RelativeLayout
android:id="#+id/titleBar"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:visibility="visible"
>
<android.support.v4.view.ViewPager
android:id="#+id/viewPagerSlider"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:overScrollMode="never"
/>
<io.colomb.android.colombio.customviews.CirclePageIndicator
android:id="#+id/slideIndicator"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="10dp"
android:layout_centerHorizontal="true"
android:layout_alignBottom="#id/viewPagerSlider"
android:layout_marginBottom="20dp"
android:paddingRight="5dp"
android:paddingLeft="5dp"
/>
</RelativeLayout>
<ImageView
android:id="#+id/ivSoftboardLogo"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/logosoftboard"
android:layout_gravity="center_horizontal"
android:contentDescription="#string/app_name"
android:layout_marginTop="10dp"
android:visibility="gone"
android:layout_marginBottom="15dp"
/>
<LinearLayout
android:id="#+id/InputFragment"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_weight="0.001"
android:layout_marginTop="-15dp"
>
</LinearLayout>
Any thoughts are appreciated.

OK solved. The thing that was bothering the adapter was the line gravity="bottom"in the root element. Also the pictures needed to be cropped more

Android ActionBar custom layout styling

I'm just starting android development coming from IOS and again stubbled onto a problem.
And after 1 day of trying i decided that i will ask the people of stack overflow.
So my problem:
I have an app and in the action bar (default no sherlock) i want 1 logo and 2 lines of text.
And trough the internet i fount the setCustomView for the action bar.
And the custom xml is loaded but i can't get the layout right.
So first i setup the action bar:
private void setupActionBar() {
ActionBar actionBar = getSupportActionBar();
actionBar.setDisplayShowTitleEnabled(false);
actionBar.setDisplayUseLogoEnabled(false);
actionBar.setDisplayHomeAsUpEnabled(false);
actionBar.setDisplayShowCustomEnabled(true);
actionBar.setDisplayShowHomeEnabled(false);
LayoutParams lp1 = new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);
View customNav = LayoutInflater.from(this).inflate(R.layout.actionbar, null); // layout which contains your button.
actionBar.setCustomView(customNav, lp1);
}
Than the xml:
<?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="match_parent"
android:layout_gravity="fill_horizontal"
android:orientation="horizontal"
android:background="#color/Blue">
<TextView
android:id="#+id/text_left"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/title_menu"
android:textColor="#color/White"
android:paddingLeft="5dp"
android:layout_gravity="left"/>
<ImageView
android:id="#+id/icon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/Icon"
android:layout_gravity="center"/>
<TextView
android:id="#+id/text_right"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/title_help"
android:layout_gravity="right"
android:textColor="#color/White"
android:paddingRight="5dp"/>
</LinearLayout>
But the result is something what i'm not looking for:
So what am i forgetting/doing wrong/or should i do?

try change the root layout into relative layout
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="fill_horizontal"
android:orientation="horizontal">
<TextView
android:text="left text"
android:layout_toLeftOf="#+id/icon"
android:layout_alignParentLeft="true"
android:id="#+id/text_left"
android:gravity="left"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingLeft="5dp"/>
<ImageView
android:layout_centerHorizontal="true"
android:id="#+id/icon"
android:layout_width="10dp"
android:layout_height="wrap_content"
android:src="#drawable/bg_sunrise"
android:layout_gravity="center"/>
<TextView
android:text="Right txt"
android:layout_toRightOf="#+id/icon"
android:id="#+id/text_right"
android:layout_width="match_parent"
android:gravity="right"
android:layout_height="wrap_content"
android:layout_gravity="right"
android:paddingRight="5dp"/> </RelativeLayout>

you're not getting your result because:
u need to:
if you use AppCompat theme
add to your activity layout
in code eg. in onCreate() set a toolbar to replace the action bar.

You could also use LinearLayout as a root and add android:weightSum and specify a layout_weight on the three child views.
What is android:weightSum in android, and how does it work?

Title not showing on the mainActivity

I have put up a spinner on Android Action Bar, i have placed the spinner in test.xml layout and i am calling it like this in the main activity in the OnCreate() method
ActionBar actionBar = getActionBar();
actionBar.setBackgroundDrawable(new ColorDrawable(Color.GREEN));
actionBar.setDisplayShowCustomEnabled(true);
actionBar.setCustomView(R.layout.activity_test);
setContentView(R.layout.activity_main);
actionBar.setTitle("Home");
But my title is not showing. i want to show HOME as title on that action bar what should i do?
My activity_test
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<Spinner
android:id="#+id/planets_spinner"
android:layout_width="100dp"
android:layout_height="50sp"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:background="#drawable/arrow2"
android:layout_weight="0.08"
android:drawSelectorOnTop="true" />
</RelativeLayout>

I have solved the problem by adding a textView to my activity_test, as this whole activity is showing on the ActionBar so i have added a text view and problem is solved :)
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal" >
<Spinner
android:id="#+id/planets_spinner"
android:layout_width="100dp"
android:layout_height="50sp"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:background="#drawable/arrow2"
android:drawSelectorOnTop="true" />
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottom="#+id/planets_spinner"
android:layout_alignParentLeft="true"
android:layout_marginBottom="6dp"
android:layout_marginLeft="6dp"
android:textStyle="bold"
android:textSize="20sp"
android:textColor="#ffffff"
android:text="Scene" />
</RelativeLayout>

When you set android:layout_alignParentRight="true" , RelativeLayout uses all the space including the title space and title is not displayed. You can check the behaviour by drawing a border around the RelativeLayout. But RelativeLayout doesnt consume more space if you dont use android:layout_alignParentRight="true". It doesnt consume more space if you use android:layout_alignParentLeft="true", too. It works weird for only android:layout_alignParentRight="true". In order to show a view at the right of the parent, the following worked for me:
<ImageView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/profile_image"
android:layout_width="40dp"
android:src="#drawable/ic_launcher"
android:layout_height="40dp"
android:background="?android:selectableItemBackground"
android:padding="3dp"
android:scaleType="centerCrop" />
Do not use RelativeLayout. Just the view you need.
Then you can align right with the LayoutParams shown as following:
actionBar.setCustomView(R.layout.actionbar_layout);
actionBar.setDisplayShowCustomEnabled(true);
ImageView imageProfile = (ImageView)actionBar.getCustomView();
int length = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 40, getResources().getDisplayMetrics());
Toolbar.LayoutParams layoutParams = new Toolbar.LayoutParams(
length,
length, Gravity.RIGHT
| Gravity.CENTER_VERTICAL);
imageProfile.setLayoutParams(layoutParams);
Now you should be able to view both ActionBar title and the ImageView.

Android Linear Layout - How to Keep Element At Bottom Of View?

I have a TextView which I want to pin at the bottom of a landscape activity that is using LinearLayout with vertically arranged elements.
I have set android:gravity="bottom" on the text view, but it still likes to be just below the last element of the LinearLayout exactly what I do not want it to do.
Any suggestions?

You will have to expand one of your upper views to fill the remaining space by setting android:layout_weight="1" on it. This will push your last view down to the bottom.
Here is a brief sketch of what I mean:
<LinearLayout android:orientation="vertical">
<View/>
<View android:layout_weight="1"/>
<View/>
<View android:id="#+id/bottom"/>
</LinearLayout>
where each of the child view heights is "wrap_content" and everything else is "fill_parent".

Update: I still get upvotes on this question, which is still the accepted answer and which I think I answered poorly. In the spirit of making sure the best info is out there, I have decided to update this answer.
In modern Android I would use ConstraintLayout to do this. It is more performant and straightforward.
<ConstraintLayout>
<View
android:id="#+id/view1"
...other attributes elided... />
<View
android:id="#id/view2"
app:layout_constraintTop_toBottomOf="#id/view1" />
...other attributes elided... />
...etc for other views that should be aligned top to bottom...
<TextView
app:layout_constraintBottom_toBottomOf="parent" />
If you don't want to use a ConstraintLayout, using a LinearLayout with an expanding view is a straightforward and great way to handle taking up the extra space (see the answer by #Matthew Wills). If you don't want to expand the background of any of the Views above the bottom view, you can add an invisible View to take up the space.
The answer I originally gave works but is inefficient. Inefficiency may not be a big deal for a single top level layout, but it would be a terrible implementation in a ListView or RecyclerView, and there just isn't any reason to do it since there are better ways to do it that are roughly the same level of effort and complexity if not simpler.
Take the TextView out of the LinearLayout, then put the LinearLayout and the TextView inside a RelativeLayout. Add the attribute android:layout_alignParentBottom="true" to the TextView. With all the namespace and other attributes except for the above attribute elided:
<RelativeLayout>
<LinearLayout>
<!-- All your other elements in here -->
</LinearLayout>
<TextView
android:layout_alignParentBottom="true" />
</RelativeLayout>

I think it will be perfect solution:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<!-- Other views -->
<Space
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"/>
<!-- Target view below -->
<View
android:layout_width="match_parent"
android:layout_height="wrap_content">
</LinearLayout>

Step 1 : Create two view inside a linear layout
Step 2 : First view must set to android:layout_weight="1"
Step 3 : Second view will automatically putted downwards
<LinearLayout
android:id="#+id/botton_header"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<View
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1" />
<Button
android:id="#+id/btn_health_advice"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</LinearLayout>

You should put the parameter gravity to bottom not in the textview but in the Linear Layout. Like this:
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:gravity="bottom|end">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Something"/>
</LinearLayout>

You can also use
android:layout_gravity="bottom"
for your textview

DO LIKE THIS
<LinearLayout
android:id="#+id/LinearLayouts02"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:gravity="bottom|end">
<TextView
android:id="#+id/texts1"
android:layout_height="match_parent"
android:layout_width="match_parent"
android:layout_weight="2"
android:text="#string/forgotpass"
android:padding="7dp"
android:gravity="bottom|center_horizontal"
android:paddingLeft="10dp"
android:layout_marginBottom="30dp"
android:bottomLeftRadius="10dp"
android:bottomRightRadius="50dp"
android:fontFamily="sans-serif-condensed"
android:textColor="#color/colorAccent"
android:textStyle="bold"
android:textSize="16sp"
android:topLeftRadius="10dp"
android:topRightRadius="10dp"
/>
</LinearLayout>

try this
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:orientation="vertical" >
<TextView
android:id="#+id/textViewProfileName"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="TextView" />
</LinearLayout>
