我有這樣的代碼,我會得到相同的帶DueDateTimegetSharedPreferences()在SQLiteOpenHelper
public List<DatabaseSource> getListSched() {
text = sharedPreference.getValue2(context);
String shareFact = text.toString();
List<DatabaseSource> schedList= new ArrayList<DatabaseSource>();
// Select All Query
String selectQuery = "SELECT * FROM schedTBL WHERE DueDateTime like " + shareFact;
SQLiteDatabase db = this.getReadableDatabase();
Cursor cursor = db.rawQuery(selectQuery, null);
// looping through all rows and adding to list
if (cursor.moveToFirst()) {
do {
DatabaseSource sched= new DatabaseSource();
sched.setId(Integer.parseInt(cursor.getString(0)));
sched.setSubject(cursor.getString(1));
sched.setDescription(cursor.getString(2));
sched.setDueDateTime(cursor.getString(3));
// Adding sched to list
contactList.add(sched);
} while (cursor.moveToNext());
}
// return schedlist
return schedList;
}
我這樣做是正確的?所有可用行,看來我在那裏不能使用sharedpreferences,我有SharedPreferencesUID類,我存儲下面這段代碼來獲取價值的地方我想
public String getValue2(Context context) { SharedPreferences settings; String text; //settings = PreferenceManager.getDefaultSharedPreferences(context); settings = context.getSharedPreferences(PREFS_NAME, Context.MODE_PRIVATE); text = settings.getString("dateselected", null); return text; }
可以分享用於存儲值的代碼 – iyu
public void save(Context context,String text)SharedPreferences設置; \t編輯編輯; \t \t // settings = PreferenceManager.getDefaultSharedPreferences(context); \t settings = context.getSharedPreferences(PREFS_NAME,Context.MODE_PRIVATE); // 1 \t editor = settings.edit(); // 2 \t \t editor.putString(「UID_Val」,text); // 3 \t \t editor.commit(); // 4 \t} –
正如您所提及的, 保存您使用「dateselected」作爲關鍵。但在使用「UID_Val」檢索你的時候。檢查該密鑰。這個鍵肯定是我的 – iyu
