它的工作完全在模擬器中，我甚至在bluestack上檢查它，但是當我在移動時使用它時崩潰，當我按下button1時它應該加載一個新的佈局以及當它檢查互聯網連接正常工作將Button4 ..Android的應用程序崩潰button1點擊手機，但它在仿真器中成功運行

堆棧跟蹤？這些總是有助於弄清楚發生了什麼。 – PearsonArtPhoto
另外，雖然我很欣賞包含很多代碼，但如果'button1'是錯誤，您應該發佈單擊'button1'時調用的函數，以及足夠的代碼來獲取上下文，但不是完整的文件。 ..清單很少需要... – PearsonArtPhoto
而不是猜測原因，我們應該等待堆棧跟蹤。這是什麼stacktrace是好的 – donfuxx
