Android: View.setID(int id) programmatically - how to avoid ID conflicts?

Question

I\'m adding TextViews programmatically in a for-loop and add them to an ArrayList.

How do I use TextView.setId(int id)? What Integer ID do I come up wit

Answer 1

The 'Compat' library now also supports the generateViewId() method for API levels prior 17.

Just make sure to use a version of the Compat library that is 27.1.0+

For example, in your build.gradle file, put :

implementation 'com.android.support:appcompat-v7:27.1.1

Then you can simply use the generateViewId() from the ViewCompat class instead of the View class as follow:

//Will assign a unique ID myView.id = ViewCompat.generateViewId()

Happy coding !
