    Take a look on autosizing TextView documentation: https://developer.android.com/guide/topics/ui/look-and-feel/autosizing-textview – Domin Oct 28 '18 at 10:31

Android officialy supports autosizing.for implementing dynamic size you should set autoSizeTextType attribute to uniform and set autoSizeMaxTextSize and autoSizeMinTextSize attributes to your desired size.

*attention : for apis below 26 you should use 'app' prefix for attributes instead of 'android' .

and finally you should have a textView like this for stretching text to screen-width:

                <TextView
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:maxLines="1"
                    android:text="Hello, how are you today"
                    android:textSize="100sp"
                    app:autoSizeMaxTextSize="100sp"
                    app:autoSizeMinTextSize="12sp"
                    app:autoSizeStepGranularity="2sp"
                    app:autoSizeTextType="uniform"
                    />

    as mentioned https://www.youtube.com/watch?v=JYrpEAz_A1U avoid using layout height to wrap content, instead use match_parent or specified height... otherwise this could cause unexpected results.. – Muahmmad Tayyib Dec 10 '19 at 07:41

TextViewCompat from AndroidX is the official solution for your problem.

    which works only for 26+ Android, but we can use `AppCompatTextView` and `app:autoSizeMaxTextSize="100sp" app:autoSizeMinTextSize="12sp" app:autoSizeTextType="uniform"` – user924 Feb 04 '20 at 12:00
