如何在Scroll View中使用SetItemClickListener？

Question

我需要滾動視圖和位置，以便知道打開哪個鏈接。 Textviews和列表是不可點擊的，因此我不能調用這個意圖。我讓他們設置爲假，因爲我讀了那些你需要做的事情讓孩子們去工作。我完全卡住了。

這裏是工作示例如何實現OnItemClickListener。 確保您的類實現了View.OnClickListener & AdapterView.OnItemSelectedListener，如代碼所示。 BTW OnItemClickListener將使用滾動視圖或您使用的任何其他佈局。此代碼在我的案例中使用滾動視圖正常工作。
