• BottomBar + fragment
• LinearLayout + TextView
• RadioGroup + RadioButton
• BottomNavigationBar

2. LinearLayout + TextView

以下为本人在项目中的实现效果 因为涉及到中间的动画 因此只能只能用笨一点的方法实现了

/*
     * 功能键点击事件
     */
    @Override
    public void onClick(View view) {
        switch (view.getId()) {
            //切换首页
            case R.id.btn_main:
                if (c1) {
                    initBoolean();
                    tv_main_main.setTextColor(getResources().getColor(R.color.themeColor));
                    img_main.setImageResource(R.mipmap.shouye_click_icon);
                    ChangeFragmentUtil.changeFragment(MainActivity.this, R.id.main_fragment, new MainFragment());
                    c1 = false;
                }
                break;
            //切换直播
            case R.id.btn_SopCast:
                if (c2) {
                    initBoolean();
                    tv_main_bbs.setTextColor(getResources().getColor(R.color.themeColor));
                    img_sop.setImageResource(R.mipmap.zhibo_click_icon);
                    ChangeFragmentUtil.changeFragment(MainActivity.this, R.id.main_fragment, new SopCastFragment());
                    c2 = false;
                }
                break;
            //发起众筹或者直播
            case R.id.btn_collect:
                initBoolean();
                tv_main_sellector.setTextColor(getResources().getColor(R.color.themeColor));
                operatingAnim = AnimationUtils.loadAnimation(this, R.anim.tip);
                LinearInterpolator lin = new LinearInterpolator();
                operatingAnim.setInterpolator(lin);
                img_collect.startAnimation(operatingAnim);
                popupWindow.showUp(ll_main_bottom);
                break;
            //切换社区
            case R.id.btn_bbs:
                if (c4) {
                    initBoolean();
                    tv_main_shequ.setTextColor(getResources().getColor(R.color.themeColor));
                    img_bbs.setImageResource(R.mipmap.shequ_click_icon);
                    ChangeFragmentUtil.changeFragment(MainActivity.this, R.id.main_fragment, new BBSFragment());
                    c4 = false;
                }
                break;
            //切换个人中心
            case R.id.btn_mine:
                if (c5) {
                    initBoolean();
                    tv_main_mine.setTextColor(getResources().getColor(R.color.themeColor));
                    img_mine.setImageResource(R.mipmap.wode_click_icon);
                    ChangeFragmentUtil.changeFragment(MainActivity.this, R.id.main_fragment, new MineFragment());
                    c5 = false;
                }
                break;
            default:
                break;
        }
    }



/*
     * 初始化功能键标记位
     */
    private void initBoolean() {
        c1 = true;
        c2 = true;
        c3 = true;
        c4 = true;
        c5 = true;
        img_main.setImageResource(R.mipmap.shouye_icon);
        img_mine.setImageResource(R.mipmap.wode_icon);
        img_sop.setImageResource(R.mipmap.zhibo_icon);
        img_bbs.setImageResource(R.mipmap.shequ_icon);
        //初始化字体颜色
        tv_main_mine.setTextColor(getResources().getColor(R.color.green1));
        tv_main_bbs.setTextColor(getResources().getColor(R.color.green1));
        tv_main_sellector.setTextColor(getResources().getColor(R.color.green1));
        tv_main_shequ.setTextColor(getResources().getColor(R.color.green1));
        tv_main_main.setTextColor(getResources().getColor(R.color.green1));
    }

3. RadioGroup + RadioButton

这种方法实现起来相对比较简单 ,但是有局限性,

<RadioGroup
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/rg_content_bottom"
        android:background="@drawable/bottom_tab_bg"
        android:orientation="horizontal" >

        <RadioButton
            android:id="@+id/rb_content_home"
            style="@style/bottomStyle"
            android:drawableTop="@drawable/bottom_radio_home_selector"
            android:text="首页" />

        <RadioButton
            android:id="@+id/rb_content_newscenter"
            style="@style/bottomStyle"
            android:drawableTop="@drawable/bottom_radio_newscenter_selector"
            android:text="新闻中心" />

        <RadioButton
            android:id="@+id/rb_content_smartservice"
            style="@style/bottomStyle"
            android:drawableTop="@drawable/bottom_radio_smartservice_selector"
            android:text="智慧服务" />

        <RadioButton
            android:id="@+id/rb_content_govaffairs"
            style="@style/bottomStyle"
            android:drawableTop="@drawable/bottom_radio_govaffairs_selector"
            android:text="政务" />

        <RadioButton
            android:id="@+id/rb_content_setting"
            style="@style/bottomStyle"
            android:drawableTop="@drawable/bottom_radio_setting_selector"
            android:text="设置" />
    </RadioGroup>

// 监听底部的单选按钮，当选择一个按钮时，把ViewPager切换到相应的位置
        rg_content_bottom.setOnCheckedChangeListener(new MyOnCheckedChangeListener());

class MyOnCheckedChangeListener implements OnCheckedChangeListener{

        @Override
        public void onCheckedChanged(RadioGroup group, int checkedId) {
            // 当选择一个按钮时，把ViewPager切换到相应的位置
            switch (checkedId) {
            case R.id.rb_content_home:
                vp_content_pagers.setCurrentItem(0,false);// 参数2 代表是否带滑动效果
                enableSlidingMenu(false);
                break;
            case R.id.rb_content_newscenter:
                vp_content_pagers.setCurrentItem(1,false);
                enableSlidingMenu(true);
                break;
            case R.id.rb_content_smartservice:
                vp_content_pagers.setCurrentItem(2,false);
                enableSlidingMenu(true);
                break;
            case R.id.rb_content_govaffairs:
                vp_content_pagers.setCurrentItem(3,false);
                enableSlidingMenu(true);
                break;
            case R.id.rb_content_setting:
                vp_content_pagers.setCurrentItem(4,false);
                enableSlidingMenu(false);
                break;

            default:
                break;
            }
        }
        
    }
