how to change a drawableLeft icon size on a button?

I added some icons on 4 buttons and they look so big next to the button. So how can I resize them? I used drawableLeft on the buttons to add icons.

The drawables are called deal, trophy, puzzle and megaphone. The icons are too big. The content_main.xml file:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/content_main"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"
    tools:context="tr.k12.evrim.evrimnews.MainActivity"
    tools:showIn="@layout/activity_main">




    <FrameLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/frameLayout"
        android:layout_alignParentTop="true"
        android:layout_alignParentStart="true">


        <LinearLayout

            <Button
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:text="Giriş Yap"
                android:onClick="SignIn"
                android:textStyle="bold"
                style="@style/Widget.AppCompat.Button.Colored"/>

    </LinearLayout>

</RelativeLayout>

Wrap your resource in a drawable that defines your desired size similar to:

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >

  <item
      android:drawable="@drawable/icon"
      android:width="@dimen/icon_size"
      android:height="@dimen/icon_size"
      />

</layer-list >

After that, use this drawable in your android:drawableLeft tag

Just use Google's MaterialButtons: https://material.io/develop/android/components/buttons/

app:icon
app:iconGravity
app:iconPadding
app:iconSize

You can set bounds programatically (here), this will look like this

Drawable img = ActivityName.this.getContext().getResources().getDrawable(
            R.drawable.blue_line);
img.setBounds(left, top, right, bottom);
button.setCompoundDrawables(img, null, null, null);
