4 PM – Intro To Java – William

Today We Did

1. Added 3 conversion types to the application
2. Created ConversionTypeListener.java to listen to changes in the Spinner

Homework

Continue working on TemperatureConverter:

1. Catch up if you haven’t already!! Our code can be found here: https://drive.google.com/drive/folders/1Ftsx-CYnRf3_zP2ypCEGCDhjrX3PCWrY?usp=drive_link
2. Start working on code to switch labels when selecting a new conversion:
   1. Create a new attribute in MainActivity.java called selectedConversion and initialize it to NULL
   2. Create a new method called setConversion() inside MainActivity.java that has one String parameter called selectedConversion
   3. Inside setConversion(), get the 2 labels representing the two temperature units (hint: use findViewById)
   4. Update the values of the labels using {label}.setText({text}) based on the conversionType
   5. Inside ConversionTypeListener.java, call the setConversion() method with selected conversion type inside the onItemSelected() method.
