The code below relates to my DatePicker method that you can choose a date and the TextView displays the date chosen as shown https://i.stack.imgur.com/cco6D.png
I have a saveData() and loadData() function and when I go to save the data from my DatePicker, it doesn't display the date chosen by the user after I go back into my Letter created.
I currently have a setOnClickListener within my ActivityMain that doesn't seem to be called when the app is run and also my Toast I setup within saveData() also doesn't display when the data is inputted and updated and no data is being saved within shared_prefs within Android Device File Explorer which leads me to believe these might be problems that are stopping my app from saving user-inputted data but not sure how to go abouts fixing.
Where should I input the setOnClickListener within my saveData function?
activity_layout.xml code
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/btn_timePicker"
android:text="What's the date?"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/textTime"
android:layout_marginTop="20dp"
android:textColor="#000000"
android:textSize="22sp"
android:textStyle="bold"
tools:text="@tools:sample/date/ddmmyy"/>
Here is the code in ActivityMain
