我有几个的TextView s或其他组件，无所谓。而意见有重复的ID，如： textView1，textView2，textView3 等

I've several TextViews or another component, doesn't matter. And the views have iteration ids like: textView1, textView2, textView3 etc.

只要我想用的 pre-字符串值来迭代IDS。

Simply I want to iterate ids by using pre-string values.

的伪例如：

String pre_value = "textView";

for(int i = 0; i < size; i++) {

    String usable_resource_id = pre_value + Integer.toString(pre_value);
    // So how to use these id like R.id.textView1
    // Cast or something similar

}

有什么建议？

推荐答案

您可以使用 资源＃则getIdentifier（） ，以得到一个字符串的标识符。

You can use Resources#getIdentifier() to get the identifier from a string.

但是，如果你要遍历他们，那岂不是更容易保持的id在数组或列表？

But if you are going to iterate over them, wouldn't it be easier to keep the ids in an array or a list?
