國際慣例先上圖：
tabhost布局文件，注意tabhost，tabcontent和tabs這三個id一定要正確
- 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="match_parent"
- android:layout_height="match_parent" >
- <RelativeLayout android:orientation="vertical"
- android:layout_width="match_parent"
- android:layout_height="match_parent">
- <FrameLayout android:id="@android:id/tabcontent"
- android:layout_width="match_parent"
- android:layout_height="match_parent" />
- <TabWidget android:id="@android:id/tabs"
- android:layout_width="match_parent"
- android:layout_height="wrap_content"
- android:background="@drawable/selector"
- android:layout_alignParentBottom="true">
- TabWidget>
- RelativeLayout>
- TabHost>
每一個tab項的布局文件，上面圖片下面是文字，
- xml version="1.0" encoding="utf-8"?>
- <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
- android:layout_width="match_parent"
- android:layout_height="match_parent"
- android:orientation="vertical" >
- <ImageView android:id="@+id/tab_iv_icon"
- android:layout_width="match_parent"
- android:layout_height="28.0dip"
- android:scaleType="fitCenter"/>
- <TextView android:id="@+id/tab_tv_text"
- android:layout_width="match_parent"
- android:layout_height="wrap_content"
- android:textSize="12.0sp"
- android:textColor="#FFFFFF"
- android:ellipsize="marquee"
- android:gravity="center"
- android:singleLine="true"
- android:marqueeRepeatLimit="1"/>
- LinearLayout>
最后是MainActivity繼承自TabActivity
- public class MainActivity extends TabActivity {
- private TabHost tabHost;
- private static final String HOME = "主頁";
- private static final String REFER = "提及";
- private static final String ABOUT = "關(guān)于";
- private static final String SEARCH = "搜索";
- private static final String MORE = "更多";
-
- private Intent homeIntent;
- private Intent referIntent;
- private Intent aboutIntent;
- private Intent searchIntent;
- private Intent moreIntent;
-
- public void onCreate(Bundle savedInstanceState) {
- super.onCreate(savedInstanceState);
- setContentView(R.layout.tabhost);
-
- tabHost=this.getTabHost();
- tabHost.setFocusable(true);
- prepareIntent();
- setupIntent();
-
- }
-
- private void setupIntent(){
- tabHost.addTab(buildTabSpec(HOME,R.drawable.icon_1_n, homeIntent));
- tabHost.addTab(buildTabSpec(REFER,R.drawable.icon_2_n, referIntent));
- tabHost.addTab(buildTabSpec(ABOUT,R.drawable.icon_3_n, aboutIntent));
- tabHost.addTab(buildTabSpec(SEARCH,R.drawable.icon_4_n, searchIntent));
- tabHost.addTab(buildTabSpec(MORE,R.drawable.icon_5_n, moreIntent));
- }
-
- private TabSpec buildTabSpec(String tag, int icon, Intent intent) {
- View view = View.inflate(MainActivity.this, R.layout.tab, null);
- ((ImageView)view.findViewById(R.id.tab_iv_icon)).setImageResource(icon);
- ((TextView)view.findViewById(R.id.tab_tv_text)).setText(tag);
- return tabHost.newTabSpec(tag)
- .setIndicator(view)
- .setContent(intent);
- }
-
- private void prepareIntent() {
- homeIntent=new Intent(this, HomeActivity.class);
- referIntent=new Intent(this, ReferActivity.class);
- aboutIntent=new Intent(this, AboutActivity.class);
- searchIntent=new Intent(this,SearchActivity.class);
- moreIntent=new Intent(this, MoreActivity.class);
- }
-
- }
