如何使onpagestarted和onpagefinished中使用的可見性方法檢測是否選中複選框？換句話說，我想修改和使用這個方法的checkBoxes。例如，如果R.id.checkBox1被選中，使R.id.progressbar1可見如果R.id.checkBox1和R.id.checkBox2 BOTH被選中，使R.id.progressbar2可見和不可見的R.id.progressbar1檢測CheckBox是否勾選並調用Visibility - Android

檢查能否請你試着解釋你想達到什麼樣的？或者只是在你的問題上發佈你的代碼。我認爲你的代碼中錯過了一件簡單的事情？你試過我的答案嗎？ –
我重新編輯了我的答案。你能檢查它嗎？ –
你期望達到什麼目的？這個代碼是這樣工作的;如果您選中了checkBox_one，它將顯示progressBar1。如果checkBox_one和checkBox_two同時選中，progressBar1將不可見，progressBar2將可見。 –
