Tabhost漂亮的自定义实现（背景随着选项卡滑动改变）-阿里云开发者社区

在网上找了许多资料都找不到自己想要的。

结果自己实现：

布局文件不帖出来了：

外层一个TabHost: 里面放《Linearlayout》〈TabWidget></Tabwidget><Framlayout></Framlayout></Linearlayout>

一：继承Tabhost

主代码：

tabhost=getTabHost();

final Resources resources=getResources();

//主页

TabHost.TabSpec specHome=tabhost.newTabSpec("home");

specHome.setIndicator("",resources.getDrawable(android.R.drawable.ic_menu_myplaces));

home =new Intent(MainActivity.this,HomeActivity.class);

specHome.setContent(home);

tabhost.addTab(specHome);

//搜索

TabHost.TabSpec specSearch=tabhost.newTabSpec("search");

specSearch.setIndicator("",resources.getDrawable(android.R.drawable.ic_menu_search));

search=new Intent(MainActivity.this,SearchActivity.class);

specSearch.setContent(search);

tabhost.addTab(specSearch);

// 分类

TabHost.TabSpec specClassify =tabhost.newTabSpec("classify");

specClassify.setIndicator("",resources.getDrawable(android.R.drawable.ic_menu_week));

classify=new Intent(MainActivity.this,ClassifyActivity.class);

specClassify.setContent(classify);

tabhost.addTab(specClassify);

//购物车

TabHost.TabSpec specShoppingCart=tabhost.newTabSpec("shoppingCart");

specShoppingCart.setIndicator("",resources.getDrawable(id))

//百宝箱

TabHost.TabSpec specTreasureChest=tabhost.newTabSpec("treasureChest");

specTreasureChest.setIndicator("",resources.getDrawable(android.R.drawable.ic_dialog_dialer));

treasureChest=new Intent(MainActivity.this, TreasureChestActivity.class);

specTreasureChest.setContent(treasureChest);

tabhost.addTab(specTreasureChest);

tabhost.setOnTabChangedListener(new OnTabChangeListener() {

@Override

public void onTabChanged(String tabId) {

Activity activity=getLocalActivityManager().getActivity(tabId);

if(activity!=null)

activity.onWindowFocusChanged(true);

}

});

简单的实现到这里结束：
