表达式的类型必须是数组类型，但它解析为int

Question

我在Android应用中遇到以下错误：

表达式的类型必须是数组类型，但它已解析为int

protected void onListItemClick(ListView lv, View v, int position, long id) {
    super.onListItemClick(lv, v, position, id);
    String openClass = R.array.calc_categories[position]; //error on this line
    try {
        Class selected = Class.forName("com.calculator.commonCalculatios." + openClass);
        Intent selectedIntent = new Intent(this, selected);
        startActivity(selectedIntent);

Answer 1

你可能想要这样的东西：

String openClass = getResources().getStringArray(R.array.calc_categories)[position]
