TextView text in red... "Cannot resolve symbol TextView"

Hi there,

Following along with Ben where he is talking about setting "casts" and what I am seeing in my app is not the same in his.

In his code, he has the red squiggly error line, but I do not.

This is the code in question:

TextView factLabel = (TextView) FindViewById(R.id.factTextView);

For me... "TextView" on the left side of the = is showing up as red and "(TextView) FindViewById" on the right side is showing up as red.

Also, when hovering over each of them I get a different popup...

For TextView I get "Cannot resolve symbol 'TextView' "

For (TextView) I get "Cannot resolve symbol 'TextView' "

And for FindViewById I get "Cannot resolve method 'FindViewById(int)' "

Not really sure why I am not getting the same output as Ben...

Hope this makes any sense....

Any help would be great!

Thanks!

you need to import the TextView class. add the following to the top of your file with the other import statements:

import android.widget.TextView;

its important to use auto complete when typing out class names. if you use auto complete the class will auto import for you. if you dont choose the auto complete value, you have to import it manually

Thanks! This fixed the TextView problem but I am still getting "FindViewById" still showing up as red with the same error "Cannot resolve method 'FindViewById(int)' "

dont capitalize the f in find

TextView factLabel = (TextView) findViewById(R.id.factTextView);

method names start with a lower case letter

make sure you check for your imports and also how you wrote that id in xml.

If you hover over the red TextView and press Alt and enter it will automatically add it to the imports.
