FragmentTabHost简单小例子

Tab页面的布局R.layout.tabhost_layout：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >


    <FrameLayout
        android:id="@+id/tab_center_fl"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1" >
    </FrameLayout>

    <android.support.v4.app.FragmentTabHost
        android:id="@+id/tabhost"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="#ff00ff" >

        <TabHost
            android:id="@+id/tabs"
            android:layout_width="match_parent"
            android:layout_height="wrap_content" >
        </TabHost>

        <FrameLayout
            android:id="@+id/tab_content_fl"
            android:layout_width="match_parent"
            android:layout_height="wrap_content" >
        </FrameLayout>
    </android.support.v4.app.FragmentTabHost>

</LinearLayout>

界面代码：

public class TabhostActivity extends FragmentActivity {
private FragmentTabHost mFragmentTabHost;
@SuppressWarnings("rawtypes")
private Class fragmentArray[] = { FragmentTabOne.class,FragmentTabTwo.class,FragmentTabThree.class,};
private String titleArray[] = { "Tab_One","Tab_Two","Tab_Three" };


@Override
protected void onCreate(Bundle bundle) {
// TODO Auto-generated method stub
super.onCreate(bundle);
setContentView(R.layout.tabhost_layout);
intViews();
initTabHost();
}


private void intViews() {
mFragmentTabHost = (FragmentTabHost) findViewById(R.id.tabhost);
}


private void initTabHost() {
mFragmentTabHost.setup(this,getSupportFragmentManager(),R.id.tab_content_fl);
mFragmentTabHost.getTabWidget().setDividerDrawable(null);


int count = fragmentArray.length;


for (int i = 0; i < count; i++) {
TabHost.TabSpec tabSpec = mFragmentTabHost.newTabSpec(titleArray[i]).setIndicator(getTabBottomView(i));
mFragmentTabHost.addTab(tabSpec,fragmentArray[i],null);
mFragmentTabHost.getTabWidget().getChildAt(i).setBackgroundResource(R.drawable.tab_bg);
}
}


private View getTabBottomView(int index) {
LayoutInflater layoutInflater = LayoutInflater.from(this);
View view = layoutInflater.inflate(R.layout.tab_bottom_layout,null);//布局很简单，就是一id为bottom_tv的TextView
TextView textView = (TextView) view.findViewById(R.id.bottom_tv);
textView.setText(titleArray[index]);
return view;
}
}
