How do you remove the extra inner padding inside a Spinner button in an Android layout?

I am trying to create a Button that looks like a Spinner.
I have done this by creating a Button like this:
<Button
android:id="#+id/dateButton"
android:layout_width="150dp"
android:layout_height="wrap_content"
android:layout_toRightOf="#+id/dateLabel"
android:text="default text"
android:textSize="15sp"
style="?android:attr/spinnerStyle"
android:gravity="center_vertical|center_horizontal" />
The problem is that the text ("default text") inside the Button seems to have extra padding around it, which makes the Button look bloated and expanded in its height.
I thought that setting the layout_height for the button to "wrap_content" would fix this and make the button thinner, but it does not have any effect.
Does anyone know how to make this button's height wrap to the text inside it?
Here is the example code:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:layout_marginLeft="10dp" >
<TextView
android:id="#+id/dateLabel"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="25dp"
android:text="Select date:"
android:textSize="15sp" />
<Button
android:id="#+id/dateButton"
android:layout_width="150dp"
android:layout_height="wrap_content"
android:layout_toRightOf="#+id/dateLabel"
android:text="default text"
android:textSize="15sp"
style="?android:attr/spinnerStyle"
android:gravity="center_vertical|center_horizontal" />
</RelativeLayout>

android:gravity="center_vertical|center_horizontal" instead of this you can write
android:gravity="center" but as per your requirment just remove this line.do not add any gravity and change your height size android:layout_height="40dp"
i changed your code
<Button
android:id="#+id/dateButton"
android:layout_width="150dp"
android:layout_height="35dp"
android:layout_toRightOf="#+id/dateLabel"
android:text="default text"
style="?android:attr/spinnerStyle"
/>

The padding of this button is decided by the drawable of it. You either need to change the spinner drawable (can be done at runtime) , or provide your own drawable to the given button that would make it look like a spinner, without using the default one

Android button with icon and text

I have some buttons like this in my app:
<Button
android:id="#+id/bSearch"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="16dp"
android:text="Search"
android:textSize="24sp" />
I'm trying to create a same button with text and a icon.
android:drawableLeft doesn't work for me (Maybe it would, but i don't know how to set a max height to the icon).
So i created a LinearLayout with a ImageView and a TextView and made it act like a button:
<LinearLayout
android:id="#+id/bSearch2"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#android:drawable/btn_default"
android:clickable="true"
android:padding="16dp"
android:orientation="horizontal" >
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:layout_marginLeft="5dp"
android:adjustViewBounds="true"
android:maxHeight="30dp"
android:maxWidth="30dp"
android:scaleType="fitCenter"
android:src="#drawable/search_icon" />
<TextView
android:id="#+id/tvSearchCaption"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:textSize="24sp"
android:paddingRight="30dp"
android:gravity="center"
android:text="Search" />
</LinearLayout>
My new button is exactly what i want (font size, icon and text placement).
But it doesn't look like my default buttons:
So i tried, to change the background and the text color of my new Button:
Button Search = (Button) findViewById(R.id.bSearch);
LinearLayout bSearch2 = (LinearLayout) findViewById(R.id.bSearch2);
bSearch2.setBackground(bSearch.getBackground());
TextView tvSearchCaption = (TextView)findViewById(R.id.tvSearchCaption);
tvSearchCaption.setTextColor(bSearch.getTextColors().getDefaultColor());
This gives a strange result, my old button, gets messed up:
When i change the order of these two buttons in the XML, so the "new button" goes first, it makes another strange result:
Now i noticed, that when i try to press the old button, the new one gets pressed.
Any ideas?

Try this one.
<Button
android:id="#+id/bSearch"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="16dp"
android:text="Search"
android:drawableLeft="#android:drawable/ic_menu_search"
android:textSize="24sp"/>

To add an image to left, right, top or bottom, you can use attributes like this:
android:drawableLeft
android:drawableRight
android:drawableTop
android:drawableBottom
The sample code is given above. You can also achieve this using relative layout.

You can use the Material Components Library and the MaterialButton component.
Use the app:icon and app:iconGravity="start" attributes.
Something like:
<com.google.android.material.button.MaterialButton
style="#style/Widget.MaterialComponents.Button.Icon"
app:icon="#drawable/..."
app:iconGravity="start"
../>

For anyone looking to do this dynamically then setCompoundDrawablesWithIntrinsicBounds(Drawable left, Drawable top, Drawable right, Drawable bottom) on the buttons object will assist.
Sample
Button search = (Button) findViewById(R.id.yoursearchbutton);
search.setCompoundDrawablesWithIntrinsicBounds('your_drawable',null,null,null);

This is what you really want.
<Button
android:id="#+id/settings"
android:layout_width="190dp"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:background="#color/colorAccent"
android:drawableStart="#drawable/ic_settings_black_24dp"
android:paddingStart="40dp"
android:paddingEnd="40dp"
android:text="settings"
android:textColor="#FFF" />

#Liem Vo's answer is correct if you are using android.widget.Button without any overriding. If you are overriding your theme using MaterialComponents, this will not solve the issue.
So if you are
Using com.google.android.material.button.MaterialButton
or
Overriding AppTheme using MaterialComponents
Use app:icon parameter.
<Button
android:id="#+id/bSearch"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="16dp"
android:text="Search"
android:textSize="24sp"
app:icon="#android:drawable/ic_menu_search" />

What about like this?
<Button
android:id="#+id/yourID"
android:drawableStart="#drawable/ic_flag"
android:textColor="#FFFFFF"
android:textSize="12sp"
android:textStyle="bold"
android:textAlignment="textStart"
android:background="#drawable/btn_background"
android:fontFamily="#font/YourFont"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Your Text" />

try It:-
position-> left,right,top,bottom
android:drawableposition="#android:drawable/-yourImage-"
android:drawabletop="-Yourfilesrc-"
android:drawablebottom="-Yourfilesrc-"
android:drawableleft="-Yourfilesrc-"
android:drawableright="-Yourfilesrc-"

I was experiencing the same problem with pure Button view. In my case XML solution was not usefull, because I have some logic to show/hide this icon.
There is one more solution using pure Kotlin:
(bSearch as? MaterialButton)?.let {
icon = AppCompatResources.getDrawable(context, R.drawable.search_icon)
iconGravity = MaterialButton.ICON_GRAVITY_START
}
P.S. We can cast Button to MaterialButton as fair as we can use icon param in Button: icon param is not actually Button param - it is sneaky MaterialButton param somehow working with Buttons.

How to android text alignment in a button when gravity:center is not working

I have the following :
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button"
android:gravity="left|center_vertical" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Text"
android:gravity="left|center_vertical" />
</LinearLayout
I want to get my button's text to align left. Right now its aligned in the center. The textview's text is aligned left without any problems. Is there something else I need to add? I don't really have to close and reopen my IDE because I use maven to build. Any suggestions?
ANSWER
Figured it out : set android:paddingLeft="0dp" . Done. No need for gravity there.

Instead of wrap_content give some value. Actually its working but you can't see because your width is set as wrap_content
<Button
android:layout_width="100dp"
android:layout_height="wrap_content"
android:text="Button"
android:gravity="left|center_vertical" />

When you set an object's gravity property, you're telling that object where you want its contents to be aligned. In your code, you're trying to align the text in a box that only as big as the text itself, which does nothing.
There are 2 ways to solve this problem.
A) You can set the button's width to be not wrap the content.
<Button
android:layout_width="100dp"
android:layout_height="wrap_content"
android:text="Button"
android:gravity="left|center_vertical" />
B) You can set the width of the text-view to not be wrap content.
<TextView
android:layout_width="100dp"
android:layout_height="wrap_content"
android:text="Text"
android:gravity="left|center_vertical" />
Otherwise, what you're doing right now should have some text in a button where there is no space between the edge of the text and the outside of the button. If there is space there, make sure you're not setting padding or margins in the button or text.

Positioning text within button in Android

I have a button with a symbol of an arrow. Besides, I want to have some margin between the button and the adjacent elements:
<Button
android:id="#+id/TSPrev"
style="?android:attr/buttonStyleSmall"
android:layout_width="0dp"
android:layout_height="fill_parent"
android:layout_weight="1"
android:layout_margin="10dp"
android:background="#android:color/holo_orange_light"
android:text="#string/left"
android:textSize="60sp" />
However, when I do this, the arrow appears like this:
How can I keep the text centered vertically when I have margins? Without them, the button text appears correctly.
Thanks

May be This will Help You :
<Button
android:id="#+id/notification"
style="#style/Wrap"
android:layout_margin="8dp"
android:background="#drawable/red_shape_corner"
android:drawableRight="#drawable/notification_bell"
android:paddingLeft="10dp"
android:paddingRight="10dp"
android:text="#string/str_notification"
android:textColor="#android:color/white" />
You Need to use
// Nothing but Image like Arrow etc.
android:drawableRight="#drawable/notification_bell"
// Here you can put you text
android:text="#string/str_notification"

Try using android:gravity="center".

Centering a TextView while keeping it to the right of a button?

I'm pretty sure I've done this before, but I've forgotten how.
Here's the problem:
I've got a button and a textview, and I want the textview to be centered, while the button is on the left side.
No problem? Just put them in a relativelayout, make the textview centerinparent, and the button alignparentleft.
But now I'm going to dynamically change the text, so it can potentially be written on top of the button! I'll just add toRightOf="#id/button" on the textview. No, now it's no longer centered.
I wish I could provide a screenshot, but it seems the computer is out of memory and can't do that.
Here's some code: http://pastebin.com/3N70Vjre (Since I can't paste xml...?)
<RelativeLayout
android:id="#+id/header"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true">
<Button
android:id="#+id/leftbutton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_centerVertical="true"
android:text="text!"
/>
<TextView
android:id="#+id/toptext"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#android:color/white"
android:layout_toRightOf="#id/leftbutton"
android:layout_centerInParent="true"
android:textSize="16sp"
android:textStyle="bold"
android:text="Text!"
android:singleLine="true"
/>
</RelativeLayout>

Try this (unfortunately I'm at work so can't jump into Eclipse to get you some code) -
Change the layout_width of the TextView to fill_parent.
Set the gravity of the TextView to center (so the text centers inside the TextView)
Set the layout_weight of the Button to 1 and the layout_weight of the TextView to 2. Note that you may have to fudge with these numbers to get the layout you're looking for.
This should center the text of the TextView after the Button, though it will not center the TextView itself. You can accomplish that by replacing the TextView with a container (Linear/Relative Layout) and doing the same method as above on the Layout instead of the TextView. You would then put your TextView inside the container and set the container's gravity to "center".
Hope this helps point you in the right direction :)

You can try this (pseudo-code):
<RelativeLayout>
<Button>
<LinearLayout toLeftOf="toptext" type="horizontal">
<TextView gravity="center">
</LinearLayout>
</RelativeLayout>
You might have to have the LinearLayout as width="fill_parent". Not sure if that will work nor not. You can subsequently try some of the things listed here: http://thinkandroid.wordpress.com/2010/01/14/how-to-position-views-properly-in-layouts/

Try declaring the TextView first, then aligning the button to the left of the text view. Keep in mind you may run into issues if the TextView becomes too wide.
EDIT: I see, so you're trying to do something sort of like the iPhone's header with back/next buttons (similar anyway). Try this modification. I still believe you're going to run into issues if the TextView gets large enough to hit the Button, though.
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/header"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
>
<TextView
android:id="#+id/toptext"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#android:color/white"
android:layout_alignParentCenter="true"
android:textSize="16sp"
android:textStyle="bold"
android:text="Text!"
android:singleLine="true"
/>
<Button
android:id="#+id/leftbutton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:text="text!"
/>
</RelativeLayout>
Try this FrameLayout instead. This may do more what you're expecting:
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView
android:id="#+id/toptext"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:textColor="#android:color/white"
android:textSize="16sp"
android:textStyle="bold"
android:text="Text!"
android:singleLine="true"
/>
<Button
android:id="#+id/leftbutton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Text!"
/>
</FrameLayout>
