How to avoid to hardcoded cast from context to activity?-CodePudding

I have MainActivity.kt with passing an activity context to MyObj-class:

class MainActivity : AppCompatActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        MyObj.processing(this)
    }
}

MyObj.kt:

class MyObj {
    companion object {
        fun processing( cx:Context ) {

            // -- doesnt work (universal way)
            val intent = cx.intent

            // -- i have to cast context to activity via hardcoded way (not universal)
            val intent = (cx as MainActivity).intent
        }
    }
}

I would like to have an universal MyObj without a need to cast in a manual way. Is it possible?

CodePudding user response：

Change Context to Activity your function will be like this:

 fun processing( ac:Activity ) {

            val intent = ac.intent

        }

CodePudding user response：

In general, it would be better not to cast anything, but rather pass in the relevant data i.e. Intent in your case:

fun processing (intent: Intent) {

     // TODO do your stuff with intent

        }
