改进一下，目标是点击菜单后把菜单收缩回去并且切换内容，我使用的是PopupWindow+RadioGroup

public class MainActivity extends TabActivity {    private PopupWindow pop;     private TabHost tabhost;    private RadioGroup radiogroup;    private RadioButton tab1,tab2;        @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.test);                //将layout的xml布局文件实例化为View类对象        LayoutInflater inflater =LayoutInflater.from(this);                View view =inflater.inflate(R.layout.mypop, null);                //创建PopupWindow，参数为显示对象，宽，高        pop =new PopupWindow(view, LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);                //PopupWindow的设置        pop.setBackgroundDrawable(new BitmapDrawable());                //点击外边消失        pop.setOutsideTouchable(true);              //设置此参数获得焦点，否则无法点击         pop.setFocusable(true);                //设置文本监听事件        TextView text =(TextView) findViewById(R.id.topmenu);        text.setOnClickListener(new OnClickListener(){            @Override            //判断是否已经显示，点击时如显示则隐藏，隐藏则显示            public void onClick(View v) {                if(pop.isShowing()){                    pop.dismiss();                }else{                    pop.showAsDropDown(v);                }                            }                                 });                           //tabhost        tabhost=getTabHost();        tabhost.addTab(tabhost.newTabSpec("a").setContent(R.id.tab1).setIndicator("a"));        tabhost.addTab(tabhost.newTabSpec("b").setContent(R.id.tab2).setIndicator("b"));              //选项        radiogroup = (RadioGroup) view.findViewById(R.id.radiogroup);          //设置radiobutton监听事件       radioCheckListener l =new radioCheckListener();       radiogroup.setOnCheckedChangeListener(l);    }            //点击菜单，切换卡并让菜单消失    public class radioCheckListener implements OnCheckedChangeListener{        @Override        public void onCheckedChanged(RadioGroup group, int checkedId) {            // TODO Auto-generated method stub            switch(checkedId){            case R.id.tabps:                tabhost.setCurrentTab(0);                pop.dismiss();                break;            case R.id.tabhtml:                tabhost.setCurrentTab(1);                pop.dismiss();                break;            }                                          }           }  }

菜单布局：

<?xml version="1.0" encoding="utf-8"?>    <RadioGroup xmlns:android="http://schemas.android.com/apk/res/android"         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:orientation="vertical"         android:background="#393C39"         android:padding="10dp"         android:id="@+id/radiogroup"         >                  <RadioButton                         android:id="@+id/tabps"             android:layout_width="match_parent"             android:layout_height="match_parent"             android:text="Photoshop"               android:textColor="#ffffff"               android:checked="true"             />                   <RadioButton               android:id="@+id/tabhtml"             android:layout_width="match_parent"             android:layout_height="match_parent"             android:textColor="#ffffff"             android:text="HTML"             />     </RadioGroup>

主布局：

<?xml version="1.0" encoding="utf-8"?><TabHost xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:id="@android:id/tabhost"     ><LinearLayout     android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical"     >    <LinearLayout        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:background="@drawable/titlebg"        android:gravity="center"        android:orientation="vertical" >        <TextView            android:id="@+id/topmenu"            android:layout_width="wrap_content"            android:layout_height="46dp"            android:clickable="true"            android:drawableRight="@drawable/ic_menu_trangle_down"            android:gravity="center_vertical"            android:text="全部课程"            android:textColor="#ffffff" />    </LinearLayout>         <TabWidget         android:layout_width="match_parent"        android:layout_height="wrap_content"        android:id="@android:id/tabs"        android:visibility="gone"        >            </TabWidget>        <FrameLayout         android:layout_width="match_parent"        android:layout_height="match_parent"        android:id="@android:id/tabcontent"        >        <LinearLayout             android:id="@+id/tab1"            android:layout_width="match_parent"            android:layout_height="match_parent"            android:orientation="vertical"            android:background="#ff0000"            ></LinearLayout>         <LinearLayout             android:id="@+id/tab2"            android:layout_width="match_parent"            android:layout_height="match_parent"            android:orientation="vertical"            android:background="#000000"            ></LinearLayout>    </FrameLayout></LinearLayout></TabHost>
