主要通過SharedPreferences進(jìn)行存儲(chǔ)，難點(diǎn)主要是1.倒序顯示 2.去重 3.最多顯示n條。話不多說看代碼

private final static String PREFERENCE_NAME = "superservice_ly";
private final static String SEARCH_HISTORY="linya_history";
// 保存搜索記錄
    public static void saveSearchHistory(String inputText) {
        SharedPreferences sp = App.context.getSharedPreferences(PREFERENCE_NAME, Context.MODE_PRIVATE);
        if (TextUtils.isEmpty(inputText)) {
            return;
        }
        String longHistory = sp.getString(SEARCH_HISTORY, "");  //獲取之前保存的歷史記錄
        String[] tmpHistory = longHistory.split(","); //逗號(hào)截取 保存在數(shù)組中
        List<String> historyList = new ArrayList<String>(Arrays.asList(tmpHistory)); //將改數(shù)組轉(zhuǎn)換成ArrayList
        SharedPreferences.Editor editor = sp.edit();
        if (historyList.size() > 0) {
            //1.移除之前重復(fù)添加的元素
            for (int i = 0; i < historyList.size(); i++) {
                if (inputText.equals(historyList.get(i))) {
                    historyList.remove(i);
                    break;
                }
            }
            historyList.add(0, inputText); //將新輸入的文字添加集合的第0位也就是最前面(2.倒序)
            if (historyList.size() > 8) {
                historyList.remove(historyList.size() - 1); //3.最多保存8條搜索記錄 刪除最早搜索的那一項(xiàng)
            }
            //逗號(hào)拼接
            StringBuilder sb = new StringBuilder();
            for (int i = 0; i < historyList.size(); i++) {
                sb.append(historyList.get(i) + ",");
            }
            //保存到sp
            editor.putString(SEARCH_HISTORY, sb.toString());
            editor.commit();
        } else {
            //之前未添加過
            editor.putString(SEARCH_HISTORY, inputText + ",");
            editor.commit();
        }
    }
//獲取搜索記錄
    public static List<String> getSearchHistory(){
        SharedPreferences sp = App.context.getSharedPreferences(PREFERENCE_NAME, Context.MODE_PRIVATE);
        String longHistory =sp.getString(SEARCH_HISTORY, "");
        String[] tmpHistory = longHistory.split(","); //split后長度為1有一個(gè)空串對(duì)象
        List<String> historyList = new ArrayList<String>(Arrays.asList(tmpHistory));
        if (historyList.size() == 1 && historyList.get(0).equals("")) { //如果沒有搜索記錄，split之后第0位是個(gè)空串的情況下
            historyList.clear();  //清空集合，這個(gè)很關(guān)鍵
        }
        return historyList;
    }

代碼就這些，放到你的工具類里面，在你需要的地方調(diào)用就好了。
