mExpandableListView.setOnChildClickListener(new OnChildClickListener() {



            @Override

            public boolean onChildClick(ExpandableListView parent, View v, int groupPosition, int childPosition, long id) {

                if (mOnSeletedListener == null) {

                    return false;

                }



                // 去掉上一次选中的项

                mListItems.get(mGroupPosition).getGroups().get(mChildPosition).setSelected(false);

                

                mGroupPosition = groupPosition;

                mChildPosition = childPosition;



                // 选中当前选择的项

                mListItems.get(mGroupPosition).getGroups().get(mChildPosition).setSelected(true);

                mExListViewAdapter.notifyDataSetChanged();

                

                mOnSeletedListener.seletedChildView(groupPosition, childPosition);

                

                return true;

            }

        });

4、修改二级菜单的selector（left_panel_item_selector.xml）配置文件如下：


<?xml version="1.0" encoding="utf-8"?>

<selector xmlns:android="http://schemas.android.com/apk/res/android">



    <item android:drawable="@drawable/menu_item_bg_sel" android:state_selected="true"/>

    <item android:drawable="@drawable/menu_item_background_down" android:state_focused="true"/>

    <item android:drawable="@drawable/menu_item_background_down" android:state_pressed="true"/>

    <item android:drawable="@drawable/menu_item_background_up"/>



</selector>

5、在每个view（新鲜事视图、消息视图和好友视图等）类中，提供 获取顶部导航栏中左侧Menu组件，代码如下：


  /**

     * 获取顶部左侧的menu组件

     * @return

     */

    public LinearLayout getMenuView() {

        return topMenuNavbar.llShowMenu;

    }

6、在 EveryoneActivity类中，

public class EveryoneActivityextends NetworkBaseActivityimplements View.OnClickListener, onSeletedListener {}

a.获取Menu组件并为其设置单击事件监听器


 mFreshNewsLayout.getMenuView().setOnClickListener(this);

b.在单击事件处理器中添加如下代码：


 @Override

    public void onClick(View v) {

        mSlideContainer.show();

    }

以聊天列表视图为例，代码如下：```

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.FrameLayout;

import android.widget.ImageView;

import android.widget.LinearLayout;

import com.everyone.android.R;

import com.everyone.android.ui.EveryoneActivity;

import com.everyone.android.widget.TopMenuNavbar;

/**

  • @author android_ls

*/

public class ChatLayout extends FrameLayout implements OnClickListener {

/**

 * LOG打印标签

 */

private static final String TAG = ChatLayout.class.getSimpleName();



private TopMenuNavbar topMenuNavbar;



/**

 * 获取顶部左侧的menu组件

 * @return

 */

public LinearLayout getMenuView() {

    return topMenuNavbar.llShowMenu;

}



private EveryoneActivity mActivity;



public ChatLayout(EveryoneActivity activity) {

    super(activity);

    mActivity = activity;



    setupViews();

}



public ChatLayout(Context context, AttributeSet attrs) {

    super(context, attrs);

    setupViews();

}



private void setupViews() {

    final LayoutInflater mLayoutInflater = LayoutInflater.from(getContext());

    LinearLayout freshNewsViewRoot = (LinearLayout) mLayoutInflater.inflate(R.layout.chat, null);

    addView(freshNewsViewRoot);



    topMenuNavbar = (TopMenuNavbar) freshNewsViewRoot.findViewById(R.id.rl_top_menu_navbar);

    LinearLayout llDownOperation = topMenuNavbar.mLlRefresh;

    ImageView ivOperation = (ImageView) llDownOperation.findViewById(R.id.iv_refresh);

    ivOperation.setImageResource(R.drawable.v5_0_1_flipper_head_add_chat_friends);



    topMenuNavbar.mLlDownList.setOnClickListener(this);

    topMenuNavbar.ivRightLine.setVisibility(View.GONE);

    topMenuNavbar.tvRightOperationName.setVisibility(View.GONE);



    topMenuNavbar.tvTitle.setText("聊天");

    topMenuNavbar.ivDownListIcon.setVisibility(View.GONE);



}



@Override

public void onClick(View v) {
