android SharedPreferences封裝類 簡單 好用

在項目中經常會用到SharedPreferences儲存一些臨時文件,如登錄賬號.密碼 ,ip等 ,有時候想起來就寫一個,弄的項目很亂,在此封裝好了一個類,代碼如下:

public class mySharePreferences {
	public static final String SERVER_IP = "mServerIP";
	public static final String SERVER_PORT = "mServerPort";
	public static final String SERVER_NAME = "mServerName";
	SharedPreferences sharedPreferences;
	Editor editor;

	private mySharePreferences() {
	};

	public static mySharePreferences getIntanse() {
		return Nested.mV2SharePreferences;
	}

	static class Nested {
		private static mySharePreferences mV2SharePreferences = new mySharePreferences();
	}

	public SharedPreferences.Editor getEditor() {
		if (editor == null || sharedPreferences == null) {
			editor = getSharePreferences().edit();
		}
		return editor;
	}

	public SharedPreferences getSharePreferences() {
		if (sharedPreferences == null) {
			sharedPreferences = PreferenceManager
					.getDefaultSharedPreferences(V2Application.getContext());
		}
		return sharedPreferences;
	}

	public void putStringValue(String key, String value) {
		getEditor().putString(key, value);
		getEditor().commit();
	}

	public String getStringValue(String key, String defaultValue) {
		return getSharePreferences().getString(key, defaultValue);
	}

	public void putBooleanValue(String key, boolean value) {
		getEditor().putBoolean(key, value);
		getEditor().commit();
	}

	public boolean getBooleanValue(String key, boolean defaultValue) {
		return getSharePreferences().getBoolean(key, defaultValue);
	}

調用的時候非常方便   如果要儲存數據直接調用

mySharePreferences.getintanse().putStringValue(string key,string value);

獲取數據的時候用

mySharePreferences.getintanse().getStringValue(string key,string defaultValue);

是不是感覺非常的方便
