Android應用程序循環

我試圖創造一個Android的應用程序的時間表後崩潰，但是當我按下按鈕它崩潰。我已經嘗試調試它，我發現它總是崩潰，當開關盒結束時，它不關心案件開始的順序。這是主要課程。感謝您的幫助！Android應用程序循環

你可以張貼logcat的???並嘗試打印subject1對象太... –

我們需要一個[MCVE]幫你 –

Xoce웃Пepeúpa 黑帶媒體鏈接給出了正確的答案，但一個快速的問題，我爲什麼要打印的主題嗎？我這麼問是因爲這樣我就可以在下一次:) @ cricket_007 其最少的代碼，我可以給，沒有這個就woudn't工作，或是否有更好的方法來做到這一點也許幫助我自己，只是想知道下次更好做 – Kira

移動

//new TextView with atribs 
    TextView textView = new TextView(this); 
    textView.setTextSize(25); 
    textView.setPadding(0, 0, 60, 0);

裏面的for循環。一個View不能有多個家長和相同的View不能添加多次
