How to set drawable with text in button android

I am trying to set drawable in my button but its not showing properly. Here is what I want to achieve
but I am unable to get the required results.
This is what I am doing
<androidx.appcompat.widget.AppCompatButton
android:id="#+id/btnShareStore"
style="#style/yellowButton"
android:layout_marginTop="#dimen/margin_large"
android:layout_marginBottom="#dimen/margin_small"
android:layout_weight="1"
android:drawableStart="#drawable/ic_vector_share"
android:text="#string/lbl_share_store"
android:layout_marginStart="#dimen/margin_large"
android:layout_marginEnd="#dimen/margin_small"/>
and this is how it looks like
How can I move drawable to the adjacent left side of text?
Any help will be highly appreciated

You can try with this, keep in mind that it will need your app theme to be a descendant of MaterialTheme.
<com.google.android.material.button.MaterialButton
app:icon="#drawable/icon_search"
android:text="Hello"
app:iconGravity="textStart"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>

Android button elevation shadow not working

I am trying to make a button that has a shadow using elevation with a background image being my sign in with gmail png. The button is contained within a relative layout. The elevation won't show no matter what I try to do. I tried solutions from other forum questions and none worked.
Here is my code for the button
<Button
android:id="#+id/google"
android:layout_width="270dp"
android:layout_height="38dp"
android:layout_marginTop="30dp"
android:layout_centerHorizontal="true"
android:background="#drawable/google"
android:elevation="10dp"
android:layout_below="#id/slogan"/>
The google drawable is a png image that I exported from Adobe XD.
Could someone please give me a pointer on what I am doing wrong? Thanks.
Additionally, I realize that if I set the background of the button to android:color/white the shadow appears. So I think the issue is with the png drawable? Does elevation not work with png images? Is there a workaround?

Use below the line of code to show an elevation in button
android:outlineProvider="bounds" – K. Sopheak
That works, thanks!

try this I hope it helps, because another view or layout just after your button is hiding shadow
android:layout_marginBottom="16dp"

For Material Button, I tried the following and it worked
android:translationZ="5dp"

Since you're using an image, replace the <Button> tag with that of an <ImageButton>. So, your workaround code would be:
<ImageButton
android:id="#+id/google"
android:layout_width="270dp"
android:layout_height="38dp"
android:layout_marginTop="30dp"
android:layout_centerHorizontal="true"
android:src="#drawable/google"
android:elevation="10dp"
android:layout_below="#id/slogan"/>
Take note that the android:src attribute is being used here rather than the android:background attribute.
This one worked for me!

try this , I hope this help you ||
android:layout_margin="5dp"

Button styles in Android

When I place a button in a layout, it has a standard gray background. However I want to make it more like the kind of button you see in the Dialogs where it's a background-less button (e.g. the white buttons with text).
Like this
Not like this... not like this...

Old question but I just stumbled on it and have the answer (or at least I think), I really don't know if that's the best approach, but it should do the job.
<Button
android:id="#+id/sign_in_button"
style="#style/Widget.AppCompat.Button.Borderless.Colored"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
The trick here is the #style/Widget.AppCompat.Button.Borderless.Colored. Also see this answer, it explains a lot https://stackoverflow.com/a/36666660/1920068

try this
android:background="#android:color/transparent"

Just use a TextView instead, and put a click effect with the background:
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#23ac29"
android:text="Signup"
android:textSize="18sp"
android:padding="8dp"
android:background="?android:attr/selectableItemBackground"/>

Make borderless image button small on Android

There is some closeable view in my app and it has a close button in header. I want make this button borderless and small.The code:
<ImageButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
style="?android:attr/borderlessButtonStyle"
android:layout_margin="0dp"
android:padding="0dp"
android:src="#android:drawable/ic_menu_close_clear_cancel"/>
In result the button is borderless but has much empty place around cross image (button is hitted on screenshot to make empty space visible)
How could I fix it?

You should use:
android:background="?selectableItemBackgroundBorderless"

Added
android:minHeight="0dp"
android:minWidth="0dp"
android:padding="2dp"
The result
Also I'll use negative margins to place the button closer to corner.

You can use the following on your ImageButton to remove the 'border':
android:background="#android:color/transparent"
or
android:background="#null"
If you would like change the background when the user clicks the button you can create a selector. Example ImageButton doesn't highlight on click with Transparent background.

With the introduction of ConstraintLayout, you can use constraints to reduce the width of the borderless ImageButton, that's way too wide by default, by constraining it to be as wide as the height:
<android.support.constraint.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/my_closeable_view"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageButton
style="?android:attr/borderlessButtonStyle"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:contentDescription="#string/action_close"
android:src="#android:drawable/ic_menu_close_clear_cancel"
app:layout_constraintDimensionRatio="w,1:1"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintTop_toTopOf="parent" />
</android.support.constraint.ConstraintLayout>
I don't recommend you to make it any smaller than this because the touch target needs to be at least 48dp x 48dp, as for Google's Material Design guidelines, otherwise a user would have a hard time trying to touch it.
If you really need it to look like it's closer to the edges of the view, you can always use an image that's not centered (has transparent padding on one or two sides), but I'd try my best to avoid doing this workaround and try rethinking my app's design in order to accommodate the button as it is.

use textView for that..
and use textview.OnTouchListener
finally onTouch change the color of text.. thats it
or else in your code just use
android:background="#null"

Android 5.0 - ProgressBar cannot be displayed over a Button

I think the title is pretty explicit about my problem... So here is my layout :
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<Button
android:id="#+id/button_action"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Login" />
<ProgressBar
android:id="#+id/progress_bar"
android:layout_width="50dp"
android:layout_height="50dp"
android:layout_centerInParent="true"/>
</RelativeLayout>
On android SDKs < 21, no problem, the ProgressBar is correctly displayed over the Button and centered in the Button. But on Android 5.0, the ProgressBar is displayed behind the Button.
So you can see it's correctly positionned it when you activate the option "Show layout bounds" in Developer Options settings, but you can't see anything on the screen without that option.
Would anybody know how to fix this? I guess it's a matter of elevation recently introduced, but I really don't know how to take care of it.
For the record, I'm using the recently released Theme.AppCompat style from the support.v7.
EDIT:
I also tried to apply setElevation(0) and setTranslationY(0) to the Button programmatically but it didn't change anything. So I wonder if it has to deal with the elevation.

You can add the android:translationZ attribute to the ProgressBar:
<ProgressBar
android:id="#+id/progress_bar"
android:layout_width="50dp"
android:layout_height="50dp"
android:translationZ="2dp"
android:layout_centerInParent="true"/>

Same issue here, my simple "hack" was too wrap the Button into another FrameLayout.
This way I don't care about the api version and other elevation issue ;)
<FrameLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center" >
<FrameLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<Button
android:id="#+id/button_action"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Login" />
</FrameLayout>
<ProgressBar
android:id="#+id/progress_bar"
android:layout_width="50dp"
android:layout_height="50dp" />
</FrameLayout>

Same question being asked here, with a better explanation of the issue:
https://stackoverflow.com/a/27216368/235910
To quote #CommonsWare:
The problem appears Android 5.0's elevation property. Apparently,
the RelativeLayout Z-axis ordering is tied into elevation. If both
widgets have the same elevation, the RelativeLayout will determine
the Z-axis order -- you can see that if you were to switch your layout
to be both Button widgets, for example. However, if one widget
(Button) has an elevation, and another widget (ImageView) does
not, the elevation will take precedence.
You can remove the Button elevation via
android:stateListAnimator="#null" or by defining your own custom
animator. Or, you can add some elevation to your ImageView to
get it to be higher on the Z axis than is the Button.

It is better to set android:translationZ more than 2dp. Your view/widget will disappear when you press the button. I explained the reason here.
<!-- Elevation when button is pressed -->
<dimen name="button_elevation_material">1dp</dimen>
<!-- Z translation to apply when button is pressed -->
<dimen name="button_pressed_z_material">2dp</dimen>
Button have these two values and defined in the framework.

If you add 'androidx.core:core' to your build.gradle, you can use this code for API < 21:
ViewCompat.setTranslationZ(viewToElevate, 5);

By default, if you want to show a view on top of a Button, it should have an elevation of at least 2dp.
This is caused by the fact that the elevation of a button is governed by their stateListAnimator. So long as it has one, setting the elevation to the button itself doesn't do anything. The stateListAnimator of Widget.MaterialComponents.Button has a default elevation of #dimen/mtrl_btn_elevation (2dp), so that's the elevation you have to take into account.
Doing android:stateListAnimator="#null" will also work, but that will get rid of any shadow effects at the button.
