I can't understand the error: "void is an invalid type for the variable"

I was searching and can't find what does the error mean in my code:

import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemSelectedListener;
import android.widget.ArrayAdapter;
import android.widget.RadioButton;
import android.widget.Spinner;
import android.widget.TextView;
import android.app.Activity;

public class MainActivity extends Activity {

public class function implements OnItemSelectedListener {

    @Override
    public void onItemSelected(AdapterView<?> parent, View arg1, int pos,
            long id) {
        // TODO Auto-generated method stub

        String str=parent.getItemAtPosition(pos).toString();
        text.setText(str);

    }

    @Override
    public void onNothingSelected(AdapterView<?> arg0) {
        // TODO Auto-generated method stub

    }

}

Spinner spinner;
TextView text;
TextView fruta;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    spinner = (Spinner)findViewById(R.id.spinner1);
    text = (TextView)findViewById(R.id.textView1);
    ArrayAdapter<CharSequence> adapter=ArrayAdapter.createFromResource(this, R.array.spinnerarray, android.R.layout.simple_spinner_item);
    adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    spinner.setAdapter(adapter);
    spinner.setOnItemSelectedListener(new function());
    fruta = (TextView)findViewById(R.id.textView3);
    fruta.setEnabled(false);


public void frutaSelecionada (View view); {

    boolean cheked = ((RadioButton) view).isChecked();
    switch (view.getId())
      {
        case R.id.radioButton1:
        if(cheked)
        {
            fruta.setText("Maçã");
            fruta.setEnabled(true);
        }
        else
        {
            fruta.setEnabled(false);
        }
        break;
        case R.id.radioButton2:
        if(cheked)
            {
                fruta.setText("Laranja");
                fruta.setEnabled(true);
            }
            else
            {
                fruta.setEnabled(false);
            }
            break;
        case R.id.radioButton3:
        if(cheked)
            {
                fruta.setText("Uvas");
                fruta.setEnabled(true);
            }
            else
            {
                fruta.setEnabled(false);
            }
            break;

      }

}


}
}

The error is: "void is an invalid type for the variable frutaSelecionada"

If you know any site that explains something I appreciated.

Thanks.

I see two errors in the code you posted.

  1. There is no closing } for your onCreate() method.
  2. There is a ; between the closing parenthesis and open curly bracket your frutaSelecionada method.

the issue is on this line

public void frutaSelecionada (View view); {

you have a ; after the closing brackets of your method. Change it to 

public void frutaSelecionada (View view) {
