I got the error cannot find symbol Dialog. Please help.
import android.app.Activity;
import android.app.AlertDialog;
import android.app.AlertDialog.Builder;
import android.content.DialogInterface;
import android.content.DialogInterface.OnClickListener;
import android.view.MenuItem;
import android.app.Dialog;
public class MainActivity extends Activity {
protected DialogInterface.OnClickListener mDialogListener = new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
}
};
// Some code omitted!
@Override
public boolean onOptionsItemSelected(MenuItem item) {
int itemId = item.getItemId();
switch(itemId) {
case R.id.action_button:
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setItems(R.array.genres,mDialogListener);
Dialog dialog = builder.create();
dialog.show();
break;
}
return super.onOptionsItemSelected(item);
}
}

Try :
// Replace this line
// Dialog dialog = builder.create();
// with
AlertDialog dialog = builder.create();
