#CodeTogether Day 68/100

Hii folks 🙌

Today I will be continuing the same pathway in which we’ll Implement the Skip button logic and verify the ViewModel data.

Unit 3: Navigation

Pathway 2: Architecture componentsSource

https://developer.android.com/courses/android-basics-kotlin/course

Add the implementation for onSkipWord() which handles when the Skip button is clicked.

  • Similar to onSubmitWord(), we will add a condition to the onSkipWord() method. If true, display the word on the screen and reset the text field. If false and there are no more words left in this round, we will show the alert dialog with the final score.
/*
* Skips the current word without changing the score.
*/

private fun onSkipWord() {
if (viewModel.nextWord()) {
setErrorTextField(false)
updateNextWordOnScreen()
} else {
showFinalScoreDialog()
}
}
  • We will run our app. Play the game and will Notice that the Skip and Submit buttons are working as intended.
  • Now we will verify the data preserved by ViewModel, In GameViewModel, right-click on the variable currentWordCount, select Refactor > Rename... . Prefix the new name with an underscore, _currentWordCount.
  • Now we will add a backing field.
private var _currentWordCount = 0
val currentWordCount: Int
get() = _currentWordCount
  • In GameFragment inside onCreateView(), above the return statement we will add another log to print the app data, word, score, and word count.
Log.d("GameFragment", "Word: ${viewModel.currentScrambledWord} " +
"Score: ${viewModel.score} WordCount: ${viewModel.currentWordCount}")

We will notice that the app data is preserved in the ViewModel during orientation, changes will update score value and word count in the UI using LiveData and Data Binding in later codelabs.

That is all for Day68 ✅
