因為Arrays.asList會強制固定長度。

只能用以下方法把Array宣告成List,可以正常使用。

List<String> list = new LinkedList<String>(Arrays.asList(split));

僅此作為筆記。

使用 getSharedPreferences 函數儲存數據。

APP_NAME 改成 想設計的名稱,如:org.twgogo.wbf.Code_.web_browser

    public boolean set_config(String str,String name_){
        SharedPreferences sharedPref = getSharedPreferences("APP_NAME", MODE_PRIVATE);
        SharedPreferences.Editor editor = sharedPref.edit();
        editor.putString(name_, str);
        editor.apply();
        return true;
    }
   public String read_config(String name_){
        SharedPreferences sharedPref = getSharedPreferences("APP_NAME", MODE_PRIVATE);
        return sharedPref.getString(name_,"NULL");
    }

The strong do what they can and the weak suffer what they must.

Privacy is your right and ability to be yourself and express yourself without the fear that someone is looking over your shoulder and that you might be punished for being yourself, whatever that may be.

It is quality rather than quantity that matters.
