一般这种需要在自己的APP里去切换系统语言的需求是比较少的,毕竟系统设置里有了,但是万一项目中碰到这种需求,可以按照如下代码去切换,本人亲测有效

public void setLan(Locale locale) {
    		//
    
    		Class amnClass = null;
    		try {
    			amnClass = Class.forName("android.app.ActivityManagerNative");
    		} catch (ClassNotFoundException e) {
    			// TODO Auto-generated catch block
    			e.printStackTrace();
    		}
    		Object amn = null;
    		Configuration config = null;
    
    		// amn = ActivityManagerNative.getDefault();
    		Method methodGetDefault = null;
    		try {
    			methodGetDefault = amnClass.getMethod("getDefault");
    		
    		methodGetDefault.setAccessible(true);
    		
    			amn = methodGetDefault.invoke(amnClass);
    		Method methodGetConfiguration = null;
    		
    			methodGetConfiguration = amnClass.getMethod("getConfiguration");
    		
    		methodGetConfiguration.setAccessible(true);
    		
    			config = (Configuration) methodGetConfiguration.invoke(amn);
    		}catch (Exception e1) {
    			
    			e1.printStackTrace();
    		}
    		// config.userSetLocale = true;
    		Class configClass = config.getClass();
    		Field f = null;
    		
    		try {
    			f = configClass.getField("userSetLocale");
    			f.setBoolean(config, true);
    		}  catch (Exception e) {
    		
    			e.printStackTrace();
    			
    		}
    		
    		Log.d("wzh", "mCurrentLanguage" + mCurrentLanguage);
    		// set the locale to the new value
    		config.locale = locale;
    
    		// amn.updateConfiguration(config);
    		Method methodUpdateConfiguration = null;
    		try {
    			methodUpdateConfiguration = amnClass.getMethod(
    					"updateConfiguration", Configuration.class);
    		
    		methodUpdateConfiguration.setAccessible(true);
    		
    			methodUpdateConfiguration.invoke(amn, config);
    		}catch (Exception e) {
    			// TODO Auto-generated catch block
    			e.printStackTrace();
    		}
    	}

以上代码就是一个方法而已,需要切换成什么语言就传什么参数,例如:要切换成中文就调用setLan(Locale.SIMPLIFIED\_CHINESE)即可,要切换成英文就调用setLan(Locale.ENGLISH)即可
