Show/hide text with button

Issue

I am trying to show text with a button click.

Here is my onClick code:

public class Uteliv extends Activity {

    public void onCrate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_uteliv);

        TextView tidiTekst = (TextView) findViewById(R.id.tidiTekst);
        tidiTekst.setVisibility(View.GONE);

        Button tidiKnapp= (Button) findViewById(R.id.tidiKnapp);
        tidiKnapp.setOnClickListener(new OnClickListener() {

        public void onClick(View v) {
            tidiTekst.setVisibility(View.VISIBLE);

        }
     });
   }
}

What is wrong? When I test it on my phone I only get a blank page.

Solution

Unless this was a typo in your post, your problem is you haven't declared the proper Activity method

public void onCrate(Bundle savedInstanceState) {

should be

public void onCreate(Bundle savedInstanceState) {

Also, you should probably make your Views member variables (declare them before onCreate() and initialize them inside of onCreate())

Edit

To show/hide your TextView you can use getVisibility to determine what to do. So it would be something like

public void onClick(View v) {
        tidiTekst.setVisibility((tidiTekst.getVisibility() == View.Visible) 
                                                ? View.GONE : View.VISIBLE);
    }
