Android - Linkify 问题

Question

我在自定义适配器中使用的 linkify 似乎遇到了问题。出于某种原因，当我点击其中一个链接时，我收到了以下堆栈信息:

这是调用它的代码:

    TextView bot = new TextView( c );
    bot.setText(li.getBottomText());
    bot.setTextColor(Color.BLACK);
    bot.setTextSize(12);
    bot.setPadding(50, 35, 0, 10);
    Linkify.addLinks(bot, Linkify.ALL);
    rL.addView(bot,ViewGroup.LayoutParams.FILL_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);

我明白错误的意思，但我不确定如何修复它。有人有什么想法吗？ 预先感谢您的帮助!

Answer 1

事实证明，这个问题的答案比我原先想象的要简单得多。问题是，当我将上下文传递给我的自定义适配器时，我传递的是 getApplicationContext()，这与使用 this 标识符不同。

错误的方式:

Context mContext = getApplicationContext();
CustomAdapter mAdapter = new CustomAdapter( 
                mContext,
                itemList); 

正确的方法:

CustomAdapter mAdapter = new CustomAdapter( 
                this,
                itemList);
