View IDs: Hello friends, where is my wrong?

[Shafiqul]

How can I solve this?

[BeLikeAPro]

Copy-paste textView.setText(""); into onCreate function

The problem was not solved. Please tell where is my wrong.

Variable textView in function onNoButtonClick(View view) is not defined (for more check local variables and global for extra help). You can see that AIDE shows red underline there.

To fix this you have kinda a few options:

1. remove (comment with //) underlined command.
2. Make textView variable global by moving textView outside of onCreate class:

onCreate(Bundle bundle){
TextView textView = (TextView)…
}

To

private TextView textView;
onCreate(Bundle bundle){
textView = (TextView)…
}
