Activity not receiving the data from intent

Question

My main activity code is here

 class MainActivity : AppCompatActivity() { override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) setContentView(R.layout.activity_main) val button=findViewById<Button>(R.id.save) val loadButton=findViewById<Button>(R.id.load) loadButton.setOnClickListener { findViewById<EditText>(R.id.username).text } button.setOnClickListener { startActivity(Intent(this,DisplayActivity::class.java). putExtra("username",findViewById<TextView>(R.id.username).text)) } } }

My display activity code is here

 class DisplayActivity : AppCompatActivity() { override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) setContentView(R.layout.activity_display) val username=intent.getStringExtra("username").toString(); findViewById<TextView>(R.id.username1).text=username; } }

but when I click the Save Button(R.id.save) the textview is being displayed as null. Where am I going wrong?

Answer 1

Using only mEditText.text returns the Editable not String , try below code:

//...
// Rest of the code above
val loadButton = findViewById<Button>(R.id.load)
        val mEditText = findViewById<EditText>(R.id.username)
        loadButton.setOnClickListener {
            startActivity(Intent(this, DisplayActivity::class.java).apply {
                putExtra("username", mEditText.text.toString()) // <- toString()
            })
        }

And get the value like this:

class DisplayActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_display)
        val username = intent.getStringExtra("username")
        findViewById<TextView>(R.id.username1).text = username
    }
}
