Android - Resize Text to fit inside a TextView

Question

I'm trying to resize the wrapping text in a TextView to fit within its bounds. I've created a new class with the source from here and I've added it inside my layout:

            <com.util.AutoResizeTextView
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:layout_marginLeft="10dp"
                android:layout_alignLeft="@id/ivBulb"
                android:layout_marginTop="5dp"
                android:layout_marginBottom="80dp"
                android:layout_below="@id/ivBulb"
                android:layout_marginRight="10dp"
                android:id="@+id/textP"
                android:ellipsize="none"
                android:fontFamily="sans-serif"
                android:textColor="#000"
                android:textSize="100sp"/> <!--maximum size -->

The text that should be displayed inside the TextView is something like:

The sunset filled the entire sky with the deep color of rubies, setting the clouds ablaze. The waves crashed and danced along the shore, moving up and down in a graceful and gentle rhythm like they were dancing.

Some texts can be a multiline but some don't. My problem is that the text font size is small (about 35dp) and it's always the same :( I've added a ScrollView in order to be able to display all the text but I want to keep just the TextView and the text to resize

I'm new in Android development so please be gentle.

why do you need to fit the text if you have it in a Scrollview? — Mohammad Ersan, Jul 24 '17 at 09:03
I added the scrollview because my text was the same but I don't want to use it. It should be just a simple textbox — Dana, Jul 24 '17 at 09:06
ScrollView height is infinite, so the children can have as height as they need, then your AutoResizeTextView will not calculate its content correctly to resize it — Mohammad Ersan, Jul 24 '17 at 09:09
I first used it without a ScrollView but the text was the same. I set the text programmatically when the activity starts, that's why it can vary. I have some texts that can be bigger than the TextView that's why I added a ScrollView. I'll edit my question :) — Dana, Jul 24 '17 at 09:27

use from android.support.v7.widget.AppCompatTextView and set

android:ellipsize="none"
                                android:singleLine="true"
                                app:autoSizeMaxTextSize="14sp"
                                app:autoSizeMinTextSize="12sp"
                                app:autoSizeStepGranularity="0.5sp"
                                app:autoSizeTextType="uniform"

in

<android.support.v7.widget.AppCompatTextView
                                android:ellipsize="none"
                                android:singleLine="true"
                                app:autoSizeMaxTextSize="14sp"
                                app:autoSizeMinTextSize="12sp"
                                app:autoSizeStepGranularity="0.5sp"
                                app:autoSizeTextType="uniform"
                                android:layout_width="match_parent"
                                android:layout_height="wrap_content"              android:id="@+id/txt_ortopedi" 
                                android:textColor="@color/text_color"
                                android:padding="4dp" android:hint="@string/search"
                                android:gravity="clip_vertical|center_horizontal" android:layout_gravity="center"
                                android:background="@color/white"/>
