Android通訊錄模糊匹配搜索實現（號碼、首字母、簡拼、全拼）

Android通訊錄模糊匹配搜索實現（號碼、首字母、簡拼、全拼）

2013年12月10日 工作記錄 小巫在工作中碰到一個需求，要求實現通訊錄聯系人的搜索，獲取聯系人的方式有好幾種，我都有點混亂了，下面提供我最近用的一種，看起來還算比較簡潔的，它是根據mimetypes表來查的。

	// 查詢所有聯系人的姓名，電話，郵箱

	public ArrayList loadContacts() throws Exception {

		Uri uri = Uri.parse("content://com.android.contacts/contacts");

		ContentResolver resolver = this.getContentResolver();

		Cursor cursor = resolver.query(uri, new String[] { "_id" }, null, null,
				null);
		ArrayList contacts = new ArrayList();
		while (cursor.moveToNext()) {

			Contact contact = new Contact();
			int contractID = cursor.getInt(0);

			StringBuilder sb = new StringBuilder("contractID=");

			contact.setId(String.valueOf(contractID));
			sb.append(contractID);

			uri = Uri.parse("content://com.android.contacts/contacts/"
					+ contractID + "/data");

			Cursor cursor1 = resolver.query(uri, new String[] { "mimetype",
					"data1", "data2" }, null, null, null);

			while (cursor1.moveToNext()) {

				String data1 = cursor1.getString(cursor1
						.getColumnIndex("data1"));

				String mimeType = cursor1.getString(cursor1
						.getColumnIndex("mimetype"));

				if ("vnd.android.cursor.item/name".equals(mimeType)) { // 是姓名
					contact.setName(data1);
					sb.append(",name=" + data1);

				} else if ("vnd.android.cursor.item/email_v2".equals(mimeType)) { // 郵箱
					if (!TextUtils.isEmpty(data1)) {
						contact.setEmail(data1);
					}
					contacts.add(contact);
					sb.append(",email=" + data1);

				} else if ("vnd.android.cursor.item/phone_v2".equals(mimeType)) { // 手機
					contact.setNumber(data1.replaceAll("-", ""));
					sb.append(",phone=" + data1);
				}

			}
			contacts.add(contact);
			cursor1.close();

			Log.i("wwj", sb.toString());

		}

		cursor.close();
		return contacts;

	}

關於模糊匹配，我真的有點頭大，我想到的是用正則表達式來做，但需要用到第三方類庫pinyin4j.jar，我試了一下，效率都點低，明顯感覺有點慢了，假如你的通訊錄的量比較大，用這個來做確實不合時宜，或許可以進行優化的地方。

定義一個工具類

上面的代碼是我從網上搜了很久才搜到的一個demo裡面的代碼，我整合到項目當中去，發現使用pinyin4j.jar類庫效率實在有點低，所以我自己想了其他辦法，不用第三方類庫來實現。
下面是小巫的實現：
我找到一篇關於，中文字符轉換為拼音的實現類，很有用

不過我也發現了一問題，關於一個中文字符的字節數的問題，不同的編碼可能會存在中文的字節數不同的情況，比如GBK編碼的中文是2，而UTF-8的編碼是3。其實我發現這個問題也挺驚奇的，這個問題可能是我們以後編碼的時候會遇到的，一個編碼就可能把你搞死。
英文字母和中文漢字在不同字符集編碼下的字節數
