Android: Heart Shaped small button to add item to favorite

I have found an answer to a question how to create heart shaped button using vector xml.
Answer is here:
https://stackoverflow.com/a/45618554/8523262
But I am not able to get it correctly implemented in my case.
I have two buttons side by side third would be this heart-Button. However, it does not fit correctly with other two buttons. I need it smaller than what original answer has it.
Here is my xml
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:padding="7sp"
android:textSize="12sp"
>
<Button
android:id="#+id/buttonIA"
android:layout_width="0sp"
android:layout_weight=".3"
android:layout_height="25sp"
android:background="#drawable/buttondesign"
android:textColor="#color/white"
android:text="Hide Arabic Version"
/>
<Button
android:id="#+id/buttonIR"
android:layout_width="0sp"
android:layout_weight=".3"
android:layout_height="25sp"
android:background="#drawable/buttondesign"
android:textColor="#color/white"
android:layout_marginStart="7sp"
android:text="Hide Reference"
/>
<Button
android:id="#+id/buttonF"
android:layout_width="0sp"
android:layout_weight="0.3"
android:layout_height="25sp"
android:background="#drawable/buttondesign"
android:textColor="#color/white"
android:layout_marginStart="7sp"
android:text="Favorite it!"
/>
</LinearLayout>
Can anyone please tell me to resize it to look like a heart when placed inline with the two buttons I have already.
ButtonF is what I tried to set this vector as background of. Changed height/width too but didn't get it how i need it.
Thank you.

I use ImageButton Button instead of Button now. You could use ImageView too.
favoritebutton in below code is the vector xml that I shared link of in my questions, in case it helps anyone.
<ImageButton
android:id="#+id/buttonF"
android:layout_weight=".3"
android:layout_width="24dp"
android:layout_height="24dp"
android:src="#drawable/favoritebutton"
android:textColor="#color/white"
android:layout_marginStart="7dp"
android:background="#null"
/>

Android Marshmallow breaks old layout

My app was first developed for Android 2.3, but has been updated many times and currently targets V21. So I was surprised when my Nexus 5 received the Marshmallow update and found that a critical feature of my app was broken. I have a screen with a line at the top where I want two buttons at the far right and an EditText box (for search text) filling up the remainder of the screen to the left. This was my first app and I was unclear about various layout techniques, but from Android 2.3 to 5.1 this code has continued to work:
<RelativeLayout android:layout_width="match_parent"
android:layout_height="wrap_content"
style="#style/upper_detail_section"
android:elevation="#dimen/upper_elevation"
>
<Button android:id="#+id/sort"
style="#style/large_cust_btn"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:text="#string/sort"
/>
<Button android:id="#+id/clear"
style="#style/large_cust_btn"
android:layout_toLeftOf="#+id/sort"
android:layout_alignParentTop="true"
android:layout_alignWithParentIfMissing="true"
android:text="#string/clear"
/>
<EditText android:id="#+id/lookup"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_toLeftOf="#+id/clear"
android:layout_alignBaseline="#+id/clear"
android:singleLine="true"
android:hint="#string/item_search_hint"
android:scrollHorizontally="true"
android:textSize="16sp"
android:inputType="textFilter"
/>
</RelativeLayout>
Bringing this screen up in Android 6.0, the buttons are there but the EditText field completely disappears! Knowing what I know now it turned out to be a simple fix using a LinearLayout and weighting:
<LinearLayout android:layout_width="match_parent"
android:layout_height="wrap_content"
style="#style/upper_detail_section"
android:orientation="horizontal"
android:elevation="#dimen/upper_elevation"
>
<EditText android:id="#+id/lookup"
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="wrap_content"
android:singleLine="true"
android:hint="#string/item_search_hint"
android:scrollHorizontally="true"
android:textSize="16sp"
android:inputType="textFilter"
/>
<Button android:id="#+id/clear"
style="#style/large_cust_btn"
android:text="#string/clear"
android:onClick="clearClicked"
/>
<Button android:id="#+id/sort"
style="#style/large_cust_btn"
android:text="#string/sort"
android:onClick="sortClicked"
/>
</LinearLayout>
So all is well now and I'm updating the store with a new APK, but I thought I'd warn people that some layout tricks that used to work may now be broken.

If I'm understanding and reproducing your problem correctly, it's quite simple to fix your issues with RelativeLayout as well. Marshmallow only handles a width of match_parent differently. So just set it to something else like with the LinearLayout and alignParentLeft to true:
<EditText android:id="#+id/lookup"
android:layout_alignParentLeft="true"
android:layout_width="0dp"
[...] />
This yielded the same layout for me like in pre Marshmallow.

Image + Text to be centre alligned in button

I have a Button with its width as match_parent. And I want a image/icon with a text in its center. I have triedandroid:drawableStart attribute but its of no help. I don't know what I am missing. Is there any one who is also facing the same problem.
Note:This link is not solving my problem. I am attaching my button portion of xml
<Button
android:background="#drawable/blue_button"
android:id="#+id/btn_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp"
android:drawableStart="#drawable/ic_list"
android:text="#string/btn_schedule"
android:textColor="#android:color/white" />
After adding these attribute my text is coming on center but image/icon is still on left side of button. Can any body help!!!

You might want to check my answer to this question:
Android Button with text and image
Its an ugly solution but it you want the image and text to be centered as a group in the button rather than text center and drawable padded from the side then its the only way I have found.

100% working
<FrameLayout
style="?android:attr/buttonStyle"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<TextView
style="?android:attr/buttonStyle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:background="#null"
android:clickable="false"
android:drawableLeft="#android:drawable/ic_delete"
android:focusable="false"
android:gravity="center"
android:minHeight="0dp"
android:minWidth="0dp"
android:text="Button Challenge" />
from here

This works for me. Basically play with the paddingLeft and PaddingRight of the button to get the text and image close together to the center.
Note: Might be an issue with rather long texts.
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="search button"
android:drawableStart="#drawable/ic_action_search"
android:paddingLeft="60dp"
android:paddingRight="60dp"/>
</LinearLayout>

I had the same problem and I hadn't found anywhere clear solution. BUT I got some information which also help me to provide following solutions (I have chosen the second one):
Create image which will contain your image and text
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:drawableTop="#drawable/YOUR_IMAGE"
android:gravity="center_horizontal|center_vertical" />
It is not so clear and you have to add more complicated changes to your layout but it is easier to modify the text later
<FrameLayout
android:gravity="center_horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<Button
android:layout_height="50dp"
android:layout_width="match_parent" />
<TextView
android:text="sample"
android:layout_height="50dp"
android:layout_width="wrap_content"
android:drawableLeft="#drawable/YOUR_IMAGE"
android:gravity="center_horizontal|center_vertical" />
</FrameLayout>

I tried android:drawableTop
The image shown in the center of the button

Android borderless buttons

I hate to be the third person to ask this, but the previous two askings haven't seemed to answer it fully. The android design guidelines detail borderless buttons, but not how to make them. In one of the previous answers, there was a sugestion to use:
style="#android:style/Widget.Holo.Button.Borderless"
This works well for a Holo theme, but I use a lot of Holo.Light as well and
style="#android:style/Widget.Holo.Light.Button.Borderless"
Does not seem to exist. Is there a way to apply a style for such borderless buttons in Holo.Light, or better yet, simply apply a borderless tag without specifying which theme it belongs in, so the app can pick the proper style at runtime?
Holo.ButtonBar seems to fit the bill for what I am looking for, except it provides no user feedback that it's been pressed.
Also, is there a place in the documentation that lists such styles that can be applied and a description of them? No matter how much I google, and search through the docs, I can't find anything. There is just a non-descriptive list if I right click and edit style.
Any help would be appreciated.
Edit: Got a perfect answer from javram, and I wanted to add some XML for anyone interested in adding the partial borders google has adopted.
Fora horizontal divider, this works great
<View
android:id="#+id/horizontal_divider_login"
android:layout_width="match_parent"
android:layout_height="1dp"
android:layout_marginLeft="8dp"
android:layout_marginRight="8dp"
android:background="#color/holo_blue" />
and this for a vertical one:
<View
android:id="#+id/vertical_divider"
android:layout_width="1dip"
android:layout_height="match_parent"
android:layout_marginBottom="8dp"
android:layout_marginTop="8dp"
android:background="#color/holo_blue" />

Simply add the following style attribute in your Button tag:
style="?android:attr/borderlessButtonStyle"
source: http://developer.android.com/guide/topics/ui/controls/button.html#Borderless

Check out my answer here. In a nutshell the correct solution is to use the following:
android:background="?android:attr/selectableItemBackground"

At the risk of beating a dead horse, here's another (possibly better) option. AppCompat v7 defines a borderless button style. If you're already making use of the AppCompat library, just go with that:
<Button android:text="#string/borderlessButtonText" style="#style/Widget.AppCompat.Button.Borderless" />

This code will remove all background for a button:
android:background="#android:color/transparent"

Just incase anybody is looking for light-weight solution to get the borderless button for the API's that do not support the Holo theme (like I did for a long time), Im posting my solution below:
<View
android:layout_height="1dp"
android:layout_width="match_parent"
android:background="#505154"
android:layout_marginLeft="10dp" android:layout_marginRight="10dp"/>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<Button
android:id="#+id/btn_Reply"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_weight="1"
android:background="#android:color/transparent"
android:paddingBottom="15dp" android:paddingTop="15dp"
android:textColor="#5c5966"
android:text="#string/btnReplyText"/>
<View
android:layout_height="fill_parent"
android:layout_width="1dp"
android:background="#505154"
android:layout_marginBottom="7dp" android:layout_marginTop="7dp"/>
<Button
android:id="#+id/btn_Delete"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_weight="1"
android:paddingBottom="15dp" android:paddingTop="15dp"
android:textColor="#5c5966"
android:background="#android:color/transparent"
android:text="#string/btnDeleteText" />
<View
android:layout_height="fill_parent"
android:layout_width="1dp"
android:background="#505154"
android:text="#string/btnReplyText"
android:layout_marginBottom="7dp" android:layout_marginTop="7dp" />
<Button
android:id="#+id/btn_Exit"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:layout_gravity="center"
android:text="#string/btnExitText"
android:paddingBottom="15dp" android:paddingTop="15dp"
android:textColor="#5c5966"
android:background="#android:color/transparent"/>
</LinearLayout>
All you have to do is change the colours and text to suit your own background. All the best!

LinearLayout text wrap problem when having two buttons of same size plus one stretched in the center

Looks like there's a plenty of questions about centering, same size etc, but so far I didn't find the exactly my case so I dare to ask :)
What I need is a layout of three buttons like this:
[ previous ][*select*] [ next ]
where [previous] and [next] buttons are of the same size (i.e. in this case, size of the [previous] button as it is bigger), and the [*select*] button should stretch to occupy all of the available width.
Following the hints of making two buttons in LinearLayout same sized, i came up with the following xml file:
<LinearLayout
android:id="#+id/button_bar"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:orientation="horizontal" >
<Button
android:layout_width="0dip"
android:layout_height="fill_parent"
android:layout_weight="1"
android:text="Previous" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="2"
android:text="Select" />
<Button
android:layout_width="0dip"
android:layout_height="fill_parent"
android:layout_weight="1"
android:text="Next" />
</LinearLayout>
This almost works :)
Except one thing: instead of making Next button to match the size of Previous button, android makes Previous button to be the size of the Next :)
And because of this the text "Previous" gets wrapped in two lines, like
Previ
ous
Dunno if this is a bug or not, but can you advice me a workaround or some another way to achive the desired layout?
Thank you!

I'd suggest using a RelativeLayout
<RelativeLayout
android:id="#+id/buttons"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:clickable="false">
<Button
android:id="#+id/previous"
android:layout_width="30dp"
android:layout_height="wrap_content"
android:text="Previous"
android:layout_alignParentLeft="true"/>
<Button
android:id="#+id/next"
android:layout_width="30dp"
android:layout_height="wrap_content"
android:text="Next"
android:layout_alignParentRight="true"/>
<Button
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Select"
android:layout_toRightOf="#id/previous"
android:layout_toLeftOf="#id/next" />
</RelativeLayout>
This should work.

If you are including "android:layout_weight" you should give either "android:layout_width" or "android:layout_height" as "fill_parent"
modify your code like this
<LinearLayout
android:id="#+id/button_bar"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:orientation="horizontal" >
<Button
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="2"
android:text="Previous" />
<Button
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1.5"
android:text="Select" />
<Button
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="2"
android:text="Next" />

In that sort of case I would go for a TableLayout, in which you have one row, and a weight of 1 for EACH button. and the stretchColumn attribute put to column 1. Does this make any difference?

I'm not sure if you can match a size to some other besides by doing this in code. The easiest solution is probably adjusting the previous and next button widths in dp/sp units until they look good and have the select button be the only one with the layout_weight attribute.
