How to solve the problem of saving the category in our application?

Many times, when developing an application, small errors may appear that affect its overall functionality. In this case, one of those errors is that our application does not save the task category correctly. The problem lies in the mapping of our task to taskentity classes, where we forgot to include the field referring to the category. This problem is solved by entering that field in the database and performing a proper conversion from ordinal.

We can follow these steps:

1. Make sure to map the category field correctly when configuring the classes.

2. Use the ordinal in the category enum declaration to store its corresponding number.

3. Implement a fromOrdinal function that allows the conversion from the ordinal to the desired category.

4. Make the necessary adjustments to our database, which may require clearing the cache or uninstalling and reinstalling the application for the changes to take effect.

   companyum object { fun fromOrdinal(ordinal: Int?): Category? { return enumValues().getOrNull(ordinal ?: return null) } } }

How to improve the interface in the face of the appearance of the keyboard?

A crucial aspect of the user experience is how the interface adapts when the keyboard appears. On real devices, the keyboard usually resizes the available space, and our layout must reflect this correctly. To achieve this functionality, we can employ the adjustResize attribute in our Android activity settings. This setting ensures that our interface elements move according to the space taken up by the keyboard.

Update the AndroidManifest.xml in this way:

By implementing this, it ensures that content is properly accommodated as the keyboard disappears or appears. Also, add imePadding to the main composable so that it reacts properly when the keyboard is invoked.

How to handle focus and text boundaries in the description field?

When editing a text field with multiple lines, it is important to manage the focus and boundaries so that the interface is not adversely affected. Because the 'Save' button can scroll, we must limit the growth of the text field. We can use isDescriptionFocus to detect when the description field is active and set maximum and minimum line limits.

if (isDescriptionFocus) { textFieldLimits = TextFieldLimits(multiline = true, minLines = 1, maxLines = 5)} else { textFieldLimits = TextFieldLimits.Default}

How to adapt messages and states in the application?

To improve the clarity and functionality of the application, it is essential to adjust the messages of important events. For example, when selecting 'delete all' from the menu, it is good to show a clear and relevant message like 'all tasks deleted' instead of 'task updated'.

Modify the homeScreenViewModel to reflect accurate changes:

fun onDeleteAllTasks() { // Change update message when deleting all tasks. postMessage("All tasks deleted")}

Also, adjust display to not show unnecessary sections like 'pending' or 'completed' when there are no pending tasks. Implement an empty status to improve the overall presentation and ensure a more intuitive and clearer layout for the user.

Finally, reducing the length of the name of the day of the week to three letters helps prevent visual elements from overlapping unnecessarily.

Remember, it is always possible to continue enriching your application, either by adding new colors, components or even new functionalities. Don't stop experimenting and learning with every tweak you implement. Any challenge is a new learning opportunity.
