1、res/layout下2个布局activity_main.xml和textview.xml textview.xml布局 代码 <LinearLayout xmlns:android="" xmlns:tools="" android:layout_width="match_parent" android:layout_height="match_parent" android:gravity="center" >
<TextView
android:id="@+id/textView" android:layout_width="wrap_content" android:layout_height="wrap_content" /></LinearLayout>
==================
2、activity_main.xml布局
代码
<RelativeLayout xmlns:android=""
xmlns:tools="" android:layout_width="match_parent" android:layout_height="match_parent" tools:context="${relativePackage}.${activityClass}" ><!-- FragmentTabHost相当于一个容器 -->
<android.support.v4.app.FragmentTabHost android:id="@+id/fragmentTabHost" android:layout_width="match_parent" android:layout_height="match_parent" ><LinearLayout
android:id="@+id/layout_container" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="horizontal" > </LinearLayout> </android.support.v4.app.FragmentTabHost></RelativeLayout>
========================
3、源文件有2个MainActivity.java和PagerFragment.java
PagerFragment.java类
代码
public class PagerFragment extends Fragment {
private int tabIndex;
@Override public void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); tabIndex = getArguments().getInt("tabIndex"); } @Override public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { View view = inflater.inflate(R.layout.textview,container,false); TextView text = (TextView) view.findViewById(R.id.textView); switch(tabIndex){ case 0: text.setText("这是记录页面"); break; case 1: text.setText("这是联系人页面"); break; case 2: text.setText("这是收藏夹页面"); break; case 3: text.setText("这是群组页面"); break; } return view; }}
==================
MainActivity类 代码
public class MainActivity extends FragmentActivity {
private FragmentTabHost tabHost;
@Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); this.tabHost = (FragmentTabHost) this.findViewById(R.id.fragmentTabHost); FragmentManager fragmentManager = getSupportFragmentManager(); //将FragmentTabHost和布局联系起来 tabHost.setup(this, fragmentManager, R.id.layout_container); //创建tab TabSpec spec1 = tabHost.newTabSpec("a");//参数：标识 spec1.setIndicator("记录");//设置标题或 图标 Bundle bundle1 = new Bundle(); bundle1.putInt("tabIndex", 0); TabSpec spec2 = tabHost.newTabSpec("b");//参数：标识 spec2.setIndicator("联系人");//设置标题或 图标 Bundle bundle2 = new Bundle(); bundle2.putInt("tabIndex", 1); TabSpec spec3 = tabHost.newTabSpec("c");//参数：标识 spec3.setIndicator("收藏夹");//设置标题或 图标 Bundle bundle3 = new Bundle(); bundle3.putInt("tabIndex", 2); TabSpec spec4 = tabHost.newTabSpec("d");//参数：标识 spec4.setIndicator("群组");//设置标题或 图标 Bundle bundle4 = new Bundle(); bundle4.putInt("tabIndex", 3); //把TabSpec Fragment Bundle 关联起来 tabHost.addTab(spec1, PagerFragment.class, bundle1); tabHost.addTab(spec2, PagerFragment.class, bundle2); tabHost.addTab(spec3, PagerFragment.class, bundle3); tabHost.addTab(spec4, PagerFragment.class, bundle4); }}
