Changing the drawable size inside a button
Solution 1:
Adding a drawable to a button has very limited functions. You can't change the drawable size, so the best way to fix it is to add a button with an image view beside it in a linear layout like this:
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:background="@drawable/ronaldo"
android:orientation="horizontal">
<Button
android:id="@+id/button"
android:layout_width="wrap_content"
android:layout_height="80dp"
android:layout_marginEnd="10dp"
android:layout_marginRight="10dp"
android:background="@null"
android:text="Play Game"
android:textColor="#ff0000"
android:textStyle="italic" />
<ImageView
android:id="@+id/imageView"
android:layout_width="wrap_content"
android:layout_height="80dp"
android:src="@drawable/messi" />
</LinearLayout>
Solution 2:
You can also do the following if you prefer this one, but you will have to add onClickListener() for each one of them:
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:background="@drawable/ronaldo"
android:orientation="horizontal">
<Button
android:id="@+id/button"
android:layout_width="wrap_content"
android:layout_height="80dp"
android:background="@null"
android:text="Play Game"
android:textColor="#ff0000"
android:textStyle="italic" />
<ImageButton
android:id="@+id/imageButton"
android:layout_width="wrap_content"
android:layout_height="80dp"
android:src="@drawable/messi" />
</LinearLayout>
Solution 3:
As you have suggested in the comments, you would do something like this:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="80dp"
android:layout_gravity="center"
android:background="@drawable/ronaldo">
<Button
android:id="@+id/button"
android:layout_width="wrap_content"
android:layout_height="80dp"
android:layout_alignLeft="@+id/buttonLayout"
android:layout_alignRight="@+id/buttonLayout"
android:background="@null" />
<LinearLayout
android:id="@+id/buttonLayout"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal">
<TextView
android:id="@+id/textView"
android:layout_width="wrap_content"
android:layout_height="80dp"
android:gravity="center"
android:text="Play Game"
android:textAppearance="?android:attr/textAppearanceMedium"
android:textColor="#ff0000"
android:textStyle="italic" />
<ImageView
android:id="@+id/imageView"
android:layout_width="wrap_content"
android:layout_height="80dp"
android:src="@drawable/messi" />
</LinearLayout>
</RelativeLayout>
If you are using API >= 23, you can put the drawable resource within a XML file like this messi_smaller.xml
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:drawable="@drawable/messi"
android:width="smaller_width_in_dp"
android:height="smaller_height_in_dp">
</item>
</layer-list>
You must make sure to keep the drawable ratio when you set the width and the height. And just use this drawable in your button:
<Button
android:layout_width="80dp"
android:layout_height="80dp"
android:layout_gravity="center"
android:drawablePadding="10dp"
android:id="@+id/button"
android:text="Play Game"
android:background="@drawable/ronaldo"
android:drawableRight="@drawable/messi_smaller" />
By this way, you can change the drawable size just in xml code
