我已经设法在 android 4.1 中获得了没有 Tabactivity 的选项卡。我的意思是使用 FragmentActivity、片段和操作栏。我有标签每当我点击任何标签时，它都会加载每个片段。现在我的问题是我在垂直选项卡中需要相同的结构。
public class MainActivity extends FragmentActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ActionBar actionbar = getActionBar();
actionbar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
View view1 = LayoutInflater.from(this).inflate(R.layout.action_bar_layout, null);
((TextView) view1.findViewById(R.id.textView)).setText("Tab1");
ActionBar.Tab tab1 = actionbar.newTab().setCustomView(view1);
View view2 = LayoutInflater.from(this).inflate(R.layout.action_bar_layout, null);
((TextView) view2.findViewById(R.id.textView)).setText("Tab2");
ActionBar.Tab tab2 = actionbar.newTab().setCustomView(view2);
View view3 = LayoutInflater.from(this).inflate(R.layout.action_bar_layout, null);
((TextView) view3.findViewById(R.id.textView)).setText("Tab3");
ActionBar.Tab tab3 = actionbar.newTab().setCustomView(view3);
View view4 = LayoutInflater.from(this).inflate(R.layout.action_bar_layout, null);
((TextView) view4.findViewById(R.id.textView)).setText("Tab4");
ActionBar.Tab tab4 = actionbar.newTab().setCustomView(view4);
View view5 = LayoutInflater.from(this).inflate(R.layout.action_bar_layout, null);
((TextView) view5.findViewById(R.id.textView)).setText("Tab5");
ActionBar.Tab tab5 = actionbar.newTab().setCustomView(view5);
Fragment fragment1 = new Fragment1();
Fragment fragment2 = new Fragment2();
Fragment fragment3 = new Fragment3();
Fragment fragment4 = new Fragment4();
Fragment fragment5 = new Fragment5();
tab1.setTabListener(new MyTabsListener(fragment1, view1));
tab2.setTabListener(new MyTabsListener(fragment2, view2));
tab3.setTabListener(new MyTabsListener(fragment3, view3));
tab4.setTabListener(new MyTabsListener(fragment4, view4));
tab5.setTabListener(new MyTabsListener(fragment5, view5));
actionbar.addTab(tab1);
actionbar.addTab(tab2);
actionbar.addTab(tab3);
actionbar.addTab(tab4);
actionbar.addTab(tab5);
}
class MyTabsListener implements TabListener {
public Fragment fragment;
public View view;
public MyTabsListener(Fragment fragment, View view) {
this.fragment = fragment;
this.view = view;
}
@Override
public void onTabReselected(Tab tab, android.app.FragmentTransaction ft) {
System.out.println("onTabReselected");
}
@Override
public void onTabSelected(Tab tab, android.app.FragmentTransaction ft) {
((RelativeLayout) view.findViewById(R.id.rootElement)).setBackgroundColor(Color.WHITE);
((TextView) view.findViewById(R.id.textView)).setTextColor(Color.BLACK);
FragmentTransaction fragmentTransaction = getSupportFragmentManager().beginTransaction();
fragmentTransaction.replace(R.id.mainFragement, fragment);
fragmentTransaction.commit();
}
@Override
public void onTabUnselected(Tab tab, android.app.FragmentTransaction ft) {
((RelativeLayout) view.findViewById(R.id.rootElement)).setBackgroundColor(Color.BLACK);
((TextView)view.findViewById(R.id.textView)).setTextColor(Color.WHITE);
}
}
}
而我的 activity_main.xml 是，
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
android:layout_gravity="center"
android:layout_height="fill_parent"
android:layout_width="fill_parent"
android:orientation="vertical"
xmlns:android="http://schemas.android.com/apk/res/android"
>
<LinearLayout
android:id="@+id/fragment_container"
android:layout_height="match_parent"
android:layout_width="match_parent"
>
<FrameLayout
android:id="@+id/mainFragement"
android:layout_width="match_parent"
android:layout_height="match_parent" >
</FrameLayout>
</LinearLayout>
