最近研究了一下contacts源码，仿照上面自己写了一个tabhosttest程序，现整理如下：

main.xml布局文件：

android:id="@android:id/tabhost"

android:layout_width="match_parent"

android:layout_height="match_parent">

android:orientation="vertical"

android:layout_width="match_parent"

android:layout_height="match_parent">

android:layout_width="match_parent"

android:layout_height="wrap_content"

/>

android:layout_width="match_parent"

android:layout_height="0dip"

android:layout_weight="1"

/>

inner.xml文件：

android:id="@android:id/tabhost"

android:layout_width="match_parent"

android:layout_height="match_parent">

android:orientation="vertical"

android:layout_width="match_parent"

android:layout_height="match_parent">

android:layout_width="fill_parent"

android:layout_height="0dip"

android:layout_weight="1"

/>

android:layout_width="fill_parent"

android:layout_height="wrap_content"

/>

main.java (主activity类)：

package com.android.test;

private static final int tab_index_dialer = 0;

private static final int tab_index_call_log = 1;

private static final int tab_index_contacts = 2;

private tabhost mtabhost;

@override

public void oncreate(bundle savedinstancestate) {

super.oncreate(savedinstancestate);

*/

private void setcurrenttab(intent intent) {

// dismiss menu provided by any children activities

activity activity = getlocalactivitymanager().

getactivity(mtabhost.getcurrenttabtag());

if (activity != null) {

activity.closeoptionsmenu();

}

// tell the children activities that they should ignore any possible saved

// state and instead reload their state from the parent's intent

intent.putextra("", true);

// choose the tab based on the inbound intent

string componentname = intent.getcomponent().getclassname();

if (getclass().getname().equals(componentname)) {

if (false) {

//in a call, show the dialer tab(which allows going back to the call)

mtabhost.setcurrenttab(tab_index_dialer);

} else if ((intent.getflags() & intent.flag_activity_launched_from_history) != 0) {

// launched from history (long-press home) --> nothing to change

} else if (true) {

// the dialer was explicitly requested

mtabhost.setcurrenttab(tab_index_dialer);

}

}

}

}

inner.java类：

package com.android.test;

import android.app.tabactivity;

import android.content.intent;

import android.os.bundle;

import android.view.window;

import android.widget.tabhost;

import android.widget.tabwidget;

private static final int tab_index_all = 0;

private static final int tab_index_missed = 1;

private static final int tab_index_outgoing = 2;

private static final int tab_index_received = 3;

private tabhost mtabhost;

private tabwidget mtabwidget;

@override

public void oncreate(bundle savedinstancestate) {

super.oncreate(savedinstancestate);

requestwindowfeature(window.feature_no_title);

setcontentview(r.layout.inner);

mtabhost = gettabhost();

mtabhost.setontabchangedlistener(this);

setuptabs();

mtabwidget = mtabhost.gettabwidget();

mtabwidget.setstripenabled(false);

for (int i = 0; i < mtabwidget.getchildcount(); i++) {

textview tv = (textview) mtabwidget.getchildat(i).findviewbyid(

android.r.id.title);

tv.settextcolor(this.getresources().getcolorstatelist(

android.r.color.white));

tv.setpadding(0, 0, 0,(int) tv.gettextsize());

tv.settext("tab" + i);

mtabwidget.getchildat(i).getlayoutparams().height =(int ) (3* tv.gettextsize());

mtabwidget.getchildat(i).setbackgroundresource(r.drawable.tab_bg);

}

}

public void ontabchanged(string tabid) {

}

private void setuptabs() {

mtabhost.addtab(mtabhost.newtabspec("all").setindicator(

getstring(r.string.inner)).setcontent(

new intent(this, other.class)));

mtabhost.addtab(mtabhost.newtabspec("missed").setindicator(

getstring(r.string.inner)).setcontent(

new intent(this, other.class)));

mtabhost.addtab(mtabhost.newtabspec("outgoing").setindicator(

getstring(r.string.inner)).setcontent(

new intent(this, other.class)));

mtabhost.addtab(mtabhost.newtabspec("received").setindicator(

getstring(r.string.inner)).setcontent(

new intent(this, other.class)));

}

}

效果图如下：
