Question

我遇到了onOptionsItemSelected的问题。点击项目后出现错误。它在更改项目中文本的颜色后发生。

请帮忙。我做错了什么？

public boolean onCreateOptionsMenu(Menu menu) {
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.main, menu);

        MenuItem menuItem = menu.getItem(0);
        CharSequence menuTitle = menuItem.getTitle();
        SpannableString styledMenuTitle = new SpannableString(menuTitle);
        styledMenuTitle.setSpan(new ForegroundColorSpan(Color.parseColor("#FF0000")), 0, styledMenuTitle.length(), 0);
        menuItem.setTitle(styledMenuTitle);

return super.onPrepareOptionsMenu(menu);             
}


public boolean onOptionsItemSelected( MenuItem item) {

          if (item.getItemId() == R.id.action_exit) {  
             this.finish();                        
          }  
        return true;  
}       
}
