FragmentTabHost

API：http://developer.android.com/reference/android/support/v4/app/FragmentTabHost.html

1、main.xml文件

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="fill_parent"android:layout_height="fill_parent"android:orientation="vertical" ><FrameLayoutandroid:id="@+id/realtabcontent"android:layout_width="fill_parent"android:layout_height="0dip"android:layout_weight="1" /><!-- tabhost裝載5個(gè)tab的容器 --><android.support.v4.app.FragmentTabHostandroid:id="@android:id/tabhost"android:layout_width="fill_parent"android:layout_height="wrap_content" ><FrameLayoutandroid:id="@android:id/tabcontent"android:layout_width="0dp"android:layout_height="0dp"android:layout_weight="0" /></android.support.v4.app.FragmentTabHost></LinearLayout>

2、FragmentActivity中使用fragmenttabhost

(1)TabSpec的實(shí)例化：TabSpec tabSpec = mTabHost.newTabSpec(String tag).setIndicator(.....);

• setIndicator(View view); ? //Specify a view as the tab indicator.

setIndicator(getTabItemView()) private View getTabItemView(int index){View view = layoutInflater.inflate(R.layout.tab_item_view, null);ImageView imageView = (ImageView) view.findViewById(R.id.imageview);imageView.setImageResource(R.drawable.tab_home_btn);TextView textView = (TextView) view.findViewById(R.id.textview); textView.setText("首頁");return view;}

• setIndicator(CharSequence label, Drawable icon)? //Specify a label and icon as the tab indicator. label即為選項(xiàng)卡的顯示的文本

setIndicator("Android",getResources().getDrawable(R.drawable.icon_home_nor));

• setIndicator( CharSequence label)? //Specify a label as the tab indicator.

setIndicator("設(shè)置")

主要代碼：

import android.os.Bundle; import android.support.v4.app.FragmentActivity; import android.support.v4.app.FragmentTabHost;/*** This demonstrates how you can implement switching between the tabs of a* TabHost through fragments, using FragmentTabHost.*/ public class MainActivity extends FragmentActivity {private FragmentTabHost mTabHost;
@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);mTabHost = (FragmentTabHost) findViewById(android.R.id.tabhost);mTabHost.setup(this, getSupportFragmentManager(), R.id.realtabcontent);mTabHost.addTab(mTabHost.newTabSpec("首頁").setIndicator("Simple"),fragment_1.class, null);mTabHost.addTab(mTabHost.newTabSpec("分類").setIndicator("Contacts"),fragment_1.class, null);mTabHost.addTab(mTabHost.newTabSpec("排行").setIndicator("Custom"),fragment_1.class, null);mTabHost.addTab(mTabHost.newTabSpec("熱門").setIndicator("Throttle"),fragment_1.class, null);mTabHost.addTab(mTabHost.newTabSpec("設(shè)置").setIndicator("Throttle"),fragment_1.class, null);} } fragment_X.class的代碼 import android.os.Bundle; import android.support.v4.app.Fragment; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup;public class fragment_1 extends Fragment {@Overridepublic View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {View v = inflater.inflate(R.layout.fragment_1, container, false);return v;} }

3、fragment下使用fragmentabhost

?(1)fragment_1本身不需要布局文件

(2)選項(xiàng)卡默認(rèn)在頂部

import android.support.v4.app.Fragment; import android.support.v4.app.FragmentTabHost;public class fragment_1 extends Fragment {private FragmentTabHost mTabHost;@Overridepublic View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {mTabHost = new FragmentTabHost(getActivity());mTabHost.setup(getActivity(), getChildFragmentManager(), R.layout.fragment1/59);mTabHost.addTab(mTabHost.newTabSpec("simple").setIndicator("Simple"),subfragment_1.class, null);mTabHost.addTab(mTabHost.newTabSpec("contacts").setIndicator("Contacts"),subfragment_1.class, null);mTabHost.addTab(mTabHost.newTabSpec("custom").setIndicator("Custom"),subfragment_1.class, null);return mTabHost;}@Overridepublic void onDestroyView() {super.onDestroyView();mTabHost = null;} }

?

4、其他函數(shù)

mTabHost.getTabWidget().getChildAt(i).setBackgroundResource(R.drawable.selector_tab_background);

Done!
