在開發過程中，當我們的程序檢測到某個功能項沒打開或者沒設置的時候，需要我們在程序中跳轉設置頁面供用戶設置後返回我們的程序才能用我們程序的某一功能，這樣，我們就有必要去了解以下內容：
在Android SDK文檔中有這樣一個類，android.provider.Settings類提供android系統各個頁面的跳轉常量：
使用實例例：startActivity(new Intent(Settings.ACTION_WIRELESS_SETTINGS))，即可跳到android手機網絡設置頁面。
如果要launch Mobile Networks Setting頁面按如下方法：
Intent intent=new Intent(Settings.ACTION_DATA_ROAMING_SETTINGS);
ComponentName cName = new ComponentName(“com.android.phone”,”com.android.phone.Settings”);
intent.setComponent(cName);
startActivity(intent);
如果要進入Networks Operators頁面按如下方法：
Intent intent = new Intent(Intent.ACTION_MAIN);
intent.setClassName(“com.android.phone”, “com.android.phone.NetworkSetting”);
startActivity(intent);
以上為網上提供的跳轉方法是從自己軟件的包名跳轉到系統的包名，大家都知道，android特別的爛，時不時改變程序的結構，不同版本可能包名什麼不一樣的，此外，android應用層的包名若是不知道，則無法跳轉，經不認真測試，好像會報錯，個人感覺也是特別的麻煩。然而android為我們提供比startActivity更加簡便的方法，就是startActivityForResult，使用startActivityForResult跳轉設置頁面設置完成後還可以返回自己的程序頁面。下面是個人的實現方法：
比如，我要跳轉系統”輔助功能“設置頁面，則用一下代碼即可：
Intent intent = new Intent(Settings.ACTION_ACCESSIBILITY_SETTINGS);
startActivityForResult(intent, REQUESTCODE);
備注：REQUESTCODE為聲明的靜態 int 型常量
