动态切换TabHost图标

动态切换TabHost图标,今天调整布局的时候需要调整跟新浪微薄tabhost切换的那种效果

先看图

这里只copy项目中的主要代码

private int[] resArray = new int[5];//存放默认的5张图标private int[] selectResArray = new int[5];//存放选中的5张图标//把资料文件中的图片分别存放在这两个数组中去(取资源中的图片我是通过配置文件取的,具体怎么取,Google一下吧)                    int resID = getResources().getIdentifier(mainmenus.get(i).getKey(), "drawable",appInfo.packageName);// 找到底部菜单图片资源文件ID                    //选中高亮图标                    int selectResId =  getResources().getIdentifier(mainmenus.get(i).getKey()+"_sel", "drawable",appInfo.packageName);                    if (resID == 0) {                        resID = getResources().getIdentifier(                                "menu_"+ activity.toLowerCase().substring(0, 1)+ activity.substring(1), "drawable",                                appInfo.packageName);                        selectResId = getResources().getIdentifier(                                "menu_"+ activity.toLowerCase().substring(0, 1)+ activity.substring(1)+"_sel", "drawable",                                appInfo.packageName);                    }                    resArray[i] = resID;                    selectResArray[i] = selectResId;

//下面就是把数据里面的值循环放进去tabhost.setOnTabChangedListener(new OnTabChangeListener() {public void onTabChanged(String tabId) {for (int i = 0; i < tabWidget.getChildCount(); i++) {View v = tabWidget.getChildAt(i);ImageView imageView = (ImageView)v.findViewById(R.id.tab_img);imageView.setImageResource(resArray[i]);}View v = tabWidget.getChildAt(Integer.parseInt(tabId));ImageView imageView = (ImageView)v.findViewById(R.id.tab_img);imageView.setImageResource(selectResArray[Integer.parseInt(tabId)]);}});

代码就这么多,,大家看看看吧
