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
[html] view
plaincopy
<?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_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

<fragment

<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: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"

<RadioButton

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
[java] view
plaincopy
setContentView(R.layout.activity_main);
InitUI();
[java] view
plaincopy
private void InitUI(){
// get Resource R.string
InitUIString();
// set Message Number
TextView 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() {
@Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
// TODO Auto-generated method stub
switch (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);
}
}
});
}
@Override
public 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
[java] view
plaincopy
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"
};
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// TODO Auto-generated method stub
view = 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() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
// TODO Auto-generated method stub
Intent intent = new Intent(getActivity(), ListContainActivity.class);
intent.putExtra("PRESIDENTS_CONTENT",presidents[position]);
getActivity().startActivity(intent);
}
};
}
