抽象出Share SDK里面的侧滑效果

在使用share SDK时，发现里面的侧滑效果还可以，现在把它单独抽象出来，唯一有个缺陷就是每次启动时会闪一下，而它给出的DEMO也有这个现象，这个问题后面再解决。

MainActivity：

package com.home.testslidingmenu;

import m.framework.ui.widget.slidingmenu.SlidingMenu;
import android.app.Activity;
import android.content.res.Configuration;
import android.os.Bundle;
import android.view.KeyEvent;
import android.view.Window;

public class MainActivity extends Activity {
	private SlidingMenu menu;
	private int orientation;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		requestWindowFeature(Window.FEATURE_NO_TITLE);
		super.onCreate(savedInstanceState);
		orientation = getResources().getConfiguration().orientation;
		menu = new SlidingMenu(this);
		menu.setMenuItemBackground(R.color.sliding_menu_item_down,
				R.color.sliding_menu_item_release);
		menu.setMenuBackground(R.color.sliding_menu_background);
		menu.setTtleHeight(cn.sharesdk.framework.utils.R.dipToPx(this, 44));
		menu.setBodyBackground(R.color.sliding_menu_body_background);
		menu.setShadowRes(R.drawable.sliding_menu_right_shadow);
		menu.setMenuDivider(R.drawable.sliding_menu_sep);
		menu.setAdapter(new MainAdapter(menu));
		menu.triggerItem(MainAdapter.GROUP_1, MainAdapter.ITEM_1);
		setContentView(menu);
	}

	/**
	 * 屏幕旋转后，此方法会被调用，以刷新侧栏的布局
	 */
	@Override
	public void onConfigurationChanged(Configuration newConfig) {
		super.onConfigurationChanged(newConfig);
		if (orientation != newConfig.orientation) {
			orientation = newConfig.orientation;
			menu.refresh();
		}
	}

	@Override
	public boolean onKeyDown(int keyCode, KeyEvent event) {
		if (keyCode == KeyEvent.KEYCODE_BACK
				&& event.getAction() == KeyEvent.ACTION_DOWN
				&& !menu.isMenuShown()) {
			menu.showMenu();
			return true;
		}
		return super.onKeyDown(keyCode, event);
	}

}
