Android毕设之Fragment+TabHost(三)

Fragment + TabHost + RadioGroup 结合使用 , 实现底菜单的效果!

1. 使用FragMent是因为 4.0.3之后 ,摒弃了TabActivity这种用法,

Demo 效果图:

先上布局XML R.layout.activity_main

<?xml version="1.0" encoding="utf-8"?><TabHost     xmlns:android="http://schemas.android.com/apk/res/android"android:id="@android:id/tabhost"    android:layout_width="fill_parent"    android:layout_height="fill_parent">    <LinearLayout    android:orientation="vertical"    android:layout_width="fill_parent"    android:layout_height="fill_parent">    <TabWidget     android:id="@android:id/tabs"    android:layout_width="fill_parent"    android:layout_height="wrap_content"    android:layout_weight="0.0"    android:visibility="gone"/>            <include android:id="@+id/header"    layout="@layout/my_header"    android:layout_height="wrap_content"    android:layout_width="fill_parent"/>        <FrameLayout     android:id="@android:id/tabcontent"    android:layout_width="fill_parent"    android:layout_height="0.0dip"    android:layout_weight="1.0">            <fragment             android:name="com.example.coolsmile.fragment.HomeFragment"            android:id="@+id/HomeFragment"            android:layout_width="match_parent"            android:layout_height="match_parent"            />        <fragment             android:name="com.example.coolsmile.fragment.fragment_tab2"            android:id="@+id/fragment_tab2"            android:layout_width="match_parent"            android:layout_height="match_parent"            />        <fragment             android:id="@+id/fragment_tab3"            android:name="com.example.coolsmile.fragment.fragment_tab3"            android:layout_width="match_parent"            android:layout_height="match_parent"            />        <fragment             android:id="@+id/fragment_tab4"            android:name="com.example.coolsmile.fragment.fragment_tab4"            android:layout_width="match_parent"            android:layout_height="match_parent"            />        <fragment             android:id="@+id/fragment_tab5"            android:name="com.example.coolsmile.fragment.fragment_tab5"            android:layout_width="match_parent"            android:layout_height="match_parent"            />    </FrameLayout>         <RadioGroup    android:id="@+id/main_tab"    android:background="@drawable/bottom1"    android:orientation="horizontal"    android:layout_width="fill_parent"    android:layout_height="wrap_content"    android:gravity="center_vertical"    android:layout_gravity="bottom">    <RadioButton        android:id="@+id/main_tab_home"                      style="@style/MMTabButton"                      android:layout_weight="1.0"                          android:drawableTop="@drawable/menu_icon_0_normal"                      android:text="@string/main_home"/>    <RadioButton        android:id="@+id/main_tab_info"        style="@style/MMTabButton"        android:layout_weight="1.0"        android:drawableTop="@drawable/menu_icon_1_normal"        android:text="@string/main_my_info" />    <RadioButton        android:id="@+id/main_tab_news"        style="@style/MMTabButton"        android:layout_weight="1.0"        android:drawableTop="@drawable/menu_icon_2_normal"        android:text="@string/main_news" />    <RadioButton     android:id="@+id/main_tab_search"                      style="@style/MMTabButton"                      android:layout_weight="1.0"                      android:drawableTop="@drawable/menu_icon_3_normal"                      android:text="@string/main_search"/>    <RadioButton        android:id="@+id/main_tab_settings"        style="@style/MMTabButton"        android:layout_weight="1.0"        android:drawableTop="@drawable/menu_icon_3_normal"        android:focusable="false"        android:text="@string/main_settings" />    </RadioGroup>        <TextView        android:id="@+id/main_tab_new_message"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_gravity="center_horizontal|top"        android:layout_marginLeft="15dip"        android:layout_marginTop="-46dip"        android:background="@drawable/tips"        android:gravity="center"        android:textColor="#ffffff"        android:textSize="10sp"        android:visibility="visible" />      </LinearLayout></TabHost>

这里有个Fragment标签

android:name="com.example.coolsmile.fragment.HomeFragment"

这里的android:name="具体的Fragment的实现类"

这里我的Acitivty继承了FargmentActivity,onCreate方法里

setContentView(R.layout.activity_main);InitUI();

private void InitUI(){// get Resource R.stringInitUIString();// set Message NumberTextView main_tab_new_message=(TextView) findViewById(R.id.main_tab_new_message);main_tab_new_message.setVisibility(View.VISIBLE);main_tab_new_message.setText("6");tabHost = (TabHost) findViewById(android.R.id.tabhost);tabHost.setup();tabHost.addTab(tabHost.newTabSpec(main_home).setIndicator(main_home).setContent(R.id.HomeFragment));tabHost.addTab(tabHost.newTabSpec(main_my_info).setIndicator(main_my_info).setContent(R.id.fragment_tab2));tabHost.addTab(tabHost.newTabSpec(main_news).setIndicator(main_news).setContent(R.id.fragment_tab3));tabHost.addTab(tabHost.newTabSpec(main_search).setIndicator(main_search).setContent(R.id.fragment_tab4));tabHost.addTab(tabHost.newTabSpec(main_settings).setIndicator(main_settings).setContent(R.id.fragment_tab5));tabHost.setCurrentTab(0);InitClickListener();}private void InitClickListener(){RadioGroup radioGroup=(RadioGroup) this.findViewById(R.id.main_tab);radioGroup.setOnCheckedChangeListener(new OnCheckedChangeListener() {@Overridepublic void onCheckedChanged(RadioGroup group, int checkedId) {// TODO Auto-generated method stubswitch (checkedId) {case R.id.main_tab_home:tabHost.setCurrentTabByTag(main_home);break;case R.id.main_tab_info:tabHost.setCurrentTabByTag(main_my_info);break;case R.id.main_tab_news:tabHost.setCurrentTabByTag(main_news);break;case R.id.main_tab_search:tabHost.setCurrentTabByTag(main_search);break;case R.id.main_tab_settings:tabHost.setCurrentTabByTag(main_settings);break;default:tabHost.setCurrentTabByTag(main_home);}}});}@Overridepublic void onClick(View v) {}public MainHeader getHeader(){return this.header;}private void InitUIString(){main_home = getResources().getString(R.string.main_home);main_my_info = getResources().getString(R.string.main_my_info);main_news = getResources().getString(R.string.main_news);main_search = getResources().getString(R.string.main_search);main_settings = getResources().getString(R.string.main_settings);}

这里实例了一个效果图的HomeFragMent

public class HomeFragment extends Fragment{View view; String[] presidents = {         "Dwight D. Eisenhower",         "John F. Kennedy",         "Lyndon B. Johnson",         "Richard Nixon",         "Gerald Ford",         "Jimmy Carter",         "Ronald Reagan",         "George H. W. Bush",         "Bill Clinton",         "George W. Bush",         "Barack Obama"     };  @Overridepublic View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {// TODO Auto-generated method stubview = inflater.inflate(R.layout.fragment_tab1,container,false);Init();return view ;}protected void Init(){ListView list = (ListView)view.findViewById(android.R.id.list);list.setAdapter(new ArrayAdapter<String>(getActivity(),             android.R.layout.simple_list_item_1, presidents));list.setOnItemClickListener(listener);}private OnItemClickListener listener = new OnItemClickListener() {@Overridepublic void onItemClick(AdapterView<?> parent, View view, int position,long id) {// TODO Auto-generated method stubIntent intent = new Intent(getActivity(), ListContainActivity.class);                  intent.putExtra("PRESIDENTS_CONTENT",presidents[position]);         getActivity().startActivity(intent);    }};}
