public void onClick(View v) {
Toast.makeText(MainActivity.this,"You taped!",Toast.LENGTH_SHORT).show();
try {
startActivity(new Intent(MainActivity.this, FuelChoiceActivity.class));
}catch (Exception e){
System.out.println(e);
}
}
這是我的代碼。我已將新的活動添加到我的manifest.xml中。 try/catch塊沒有返回任何示例。當我按下按鈕時，執行並顯示吐司，但頁面不變。這個onClickListener在一個適配器方法'getView'中，所以它可以通過適配器生成的任何按鈕來獲得。我嘗試了其他事件，他們工作！唯一沒有的是去新的活動。意圖不開始新的活動
這裏是我的日誌當我調試，並點擊一個按鈕：

感謝您的閱讀和你的時間。我會欣賞想法。
您是否在FuelChoiceActivity的onCreate中獲得了任何記錄器 –
如果我們對FuelChoiceActivity有訪問權限，我們可以更好地瞭解這個問題 – nandsito
FuelChoiceActivity只有基本的onCreate和東西。如果我將它作爲主要工具啓動它。唯一的區別是我的主要活動擴展了Activity，FuelChoiceActivity擴展了AppCompatActivity。第二個沒有日誌 –
