第一次開通智能手機應用程序的活動

-2

晚上好，我將開始一個活動的主要佈局，第一次在智能手機上開始的應用程序，我該怎麼辦？這是我的主要活動...當我的apo開始時，您可以看到我的activity_main選擇通知從firebase收回，當我設置通知時，應用程序將您重定向到另一個activity_mainweb當我放置webview時，我想看到只有在第一次第一activity_main佈局第一次開通智能手機應用程序的活動

非常不清楚你在問什麼。 – Kuffs

爲什麼？這是一個簡單的問題，只有當應用程序第一次在智能手機上啓動時，我必須打開我的一個佈局活動。 –

爲什麼？因爲這個問題看起來像是由一個糟糕的翻譯應用程序處理，沒有任何意義。 – Kuffs

您需要使用SharedPrefs跟蹤無論是國內首家推出並重定向到另一個佈局，如果它是

private static final String KEY_HAS_BEEN_LAUNCHED_BEFORE = "KEY_HAS_BEEN_LAUNCHED"; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(this); 
    boolean hasBeenLaunchedBefore = prefs.getBoolean(KEY_HAS_BEEN_LAUNCHED_BEFORE , false); 
    setContentView(hasBeenLaunchedBefore ? R.layout.normal_layout 
             : R.layout.first_launch_layout); 
    if (!hasBeenLaunchedBefore) { 
     //after the first launch, record that it's been seen 
     final SharedPreferences.Editor editor = prefs.edit(); 
     editor.putBoolean(KEY_HAS_BEEN_LAUNCHED_BEFORE , true); 
     editor.apply(); 
    } 
}

你現在可以檢查我的問題嗎？ –

他爲你寫了整個代碼片段，你還想要更多什麼？只需複製並粘貼即可。 – Cottontree
