SlidingMenu侧拉栏

 

 

 

 

SlidingMenu的MainActivity的代码如下：

package com.woaibokeyuan.left_slidingmenu;

import com.jeremyfeinstein.slidingmenu.lib.SlidingMenu;
import com.jeremyfeinstein.slidingmenu.lib.app.SlidingFragmentActivity;

import android.os.Bundle;
import android.view.Window;
import android.app.Activity;


public class MainActivity extends SlidingFragmentActivity {

    private SlidingMenu slidingMenu;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        
        //内容布局
        setContentView(R.layout.content);
        //设置左侧侧拉栏目对应的布局文件
        setBehindContentView(R.layout.menu_frame);
        slidingMenu = getSlidingMenu();
        //设置测拉栏目所在方向
        slidingMenu.setMode(SlidingMenu.LEFT);
        //设置内容宽度-SlidingMenu划出时主页面显示的剩余宽度
        slidingMenu.setBehindOffsetRes(R.dimen.slidingmenu_offset);
        //侧拉条目设置相应的宽度
//        slidingMenu.setBehindWidth(20);
        //设置一个分割线
        slidingMenu.setShadowDrawable(R.drawable.shadow);
       //给分割线设置宽度
        slidingMenu.setShadowWidthRes(R.dimen.shadow_width);
      //侧拉栏目的触摸范围
              /*
               * SlidingMenu.TOUCHMODE_FULLSCREEN 全屏拖拽
               * SlidingMenu.TOUCHMODE_MARGIN  边缘拖拽
               * SlidingMenu.TOUCHMODE_NONE  不能拖拽
               */
        slidingMenu.setTouchModeAbove(SlidingMenu.TOUCHMODE_FULLSCREEN);
        
      //通过Fragment去替换左侧侧拉条目对应帧布局内部内容
        MenuFragment menuFragment =  new MenuFragment();
        
        //替换帧布局内部内容
        getSupportFragmentManager()
        //开启事务（数据库开启事务，效率高一些）
        .beginTransaction()
        //替换帧布局对应id,替换的fragment对象，tag
        .replace(R.id.menu, menuFragment, "MENU")
        .commit();
    }

    public void switchFragment(BaseFragment baseFragment) {
        // 暴露替换帧布局内容的操作
        if(baseFragment != null){

            getSupportFragmentManager()
            .beginTransaction()
            .replace(R.id.content_frame, baseFragment, "HOME")
            .commit();
        }
    }
    
}

 

MenuFragment:左侧侧拉栏目

package com.woaibokeyuan.zhbj.fragment;

import com.woaibokeyuan.zhbj.base.BaseFragment;

import android.view.View;
import android.widget.TextView;


public class MenuFragment extends BaseFragment {

    //返回当前Fragment对象的显示效果
    @Override
    public View initView() {
        TextView textView = new TextView(context);
        textView.setText("左侧侧拉栏目");
        return textView;
    }

    //给指定initView方法返回的view对象去填充数据
    @Override
    public void initData() {
        
    }
}

 

 

BaseFragment:

package com.woaibokeyuan.zhbj.base;

import android.content.Context;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

public abstract class BaseFragment extends Fragment {
    public View view;
    public Context context;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        this.context = getActivity();
    }
    
    //设置界面对应的view对象
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        view = initView();
        return view;
    }

    //填充数据的操作，
    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        //拿数据去填充UI
        initData();
        super.onActivityCreated(savedInstanceState);
    }

    //预设UI方法
    public abstract View initView() ;
    //数据填充UI的方法
    public abstract void initData();
}
