I'm very new to Android Studio Development and I was wondering how to do this, when I click a button on MainActivity, it will direct me to secondActivity where the text become visible (Originally TextView will not be visible until the button from MainActivity is pressed)
imageButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(MainActivity.this, SecondActivity.class);
String status = "Success!";
intent2.putExtra("Status",status);
startActivity(intent);
}
});
I want to make an if-else statement for this (on SecondActivity page) where if user straight away go to SecondActivity, it will not display any text there. But if pressed the button on MainAcitivty page, the system will go to SecondActivity with the TextView displayed.
Thanks!
Basically, there are several approaches you can do that.
button.setOnClickListener {
val intent = Intent(this@MainActivity, SecondActivity::class.java).apply {
val status = true
putExtra("Status", status)
}
startActivity(intent)
}
And in your second activity, in your need to override onCreate
to parse your intents to decide your text want to display or not.
val status = intent.extras?.getBoolean("Status")
if(status) {
hideText()
} else {
showText()
}
singleton
class to keep the status in this class, and based this singleton
class status, you may choose to hide/show your text. However this solution isn't the recommended way to do it. Because global state is bad for testing and just pollute the code.
