MainActivity.kt

공유하기 기능을 구현한다.

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

        initShareButton()
    }

    private fun initShareButton() {
        val shareButton = findViewById<AppCompatButton>(R.id.btnShare)
        shareButton.setOnClickListener {
            val shareIntent = Intent().apply {
                action = Intent.ACTION_SEND
                putExtra(
                    Intent.EXTRA_TEXT,
                    "https://devgeek.tistory.com" // 전달하려는 Data(Value)
                )
                type = "text/plain"
            }

            startActivity(Intent.createChooser(shareIntent, null))
        }
    }
}
