大家好我已经开发了我的Android应用程序..我使用过ICS操作栏：https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcQFidqbJcN2eAXLYBG8t0JAJNiqqud1ux960RvrzqRNJqgCdNXJ
如何让操作栏与姜饼兼容？
MainActivity：

import android.support.v4.app.FragmentStatePagerAdapter;
import android.support.v4.view.ViewPager;
import android.support.v7.app.ActionBarActivity;
import android.support.v7.app.ActionBar;
public class MainActivity extends ActionBarActivity {
ViewPager Tab;
TabPagerAdapter TabAdapter;
ActionBar actionBar;
public boolean StatusConnection = false;
public int thread = 0;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
TabAdapter = new TabPagerAdapter(getSupportFragmentManager());
Tab = (ViewPager)findViewById(R.id.pager);
Tab.setOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener() {
@Override
public void onPageSelected(int position) {
actionBar.setSelectedNavigationItem(
position);
Tab.setCurrentItem(position);
}
});
Tab.setAdapter(TabAdapter);
actionBar = getSupportActionBar();
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
ActionBar.TabListener tabListener = new ActionBar.TabListener(){
@Override
public void onTabReselected(ActionBar.Tab arg0,FragmentTransaction arg1) {
// TODO Auto-generated method stub
}
@Override
public void onTabSelected(ActionBar.Tab arg0,FragmentTransaction arg1) {
// TODO Auto-generated method stub
Tab.setCurrentItem(arg0.getPosition());
}
@Override
public void onTabUnselected(ActionBar.Tab arg0,FragmentTransaction arg1) {
// TODO Auto-generated method stub
}
};
actionBar.addTab(actionBar.newTab().setText("a").setTabListener(tabListener));
actionBar.addTab(actionBar.newTab().setText("b").setTabListener(tabListener));
actionBar.addTab(actionBar.newTab().setText("c").setTabListener(tabListener));
if (!isOnline()){
try {
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Connessione Internet")
.setMessage("Connessione Internet non disponibile.")
.setCancelable(false)
.setNegativeButton("Esci",new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {

finish();
}
});
AlertDialog alert = builder.create();
alert.show();
}
catch(Exception e) { }
}
}
private class TabPagerAdapter extends FragmentStatePagerAdapter {
public TabPagerAdapter(FragmentManager fm) {
super(fm);
}
@Override
public Fragment getItem(int i) {
switch (i) {
case 0:
return new info();
case 1:
return Arrivi.newInstance(thread, A_Compagnia, A_CodiceVolo, A_Citta, A_OraPrevista, A_OraStimata, A_StatoVolo);
case 2:
return Partenze.newInstance(thread, P_Compagnia, P_CodiceVolo, P_Citta, P_OraPrevista, P_OraStimata, P_StatoVolo);

return null;
}
@Override

return 3;
}
}
谢谢你们!!

Google教程here不包含向您展示如何使用标签页，viewpager和操作栏支持姜饼设备的代码。我已将其编辑为下面的姜饼。主要变化在于活动，布局是为了方便而提供的.N.B。需要添加Android支持库并将v7-appcompat作为参考库 - 请参阅here

最后记得在清单中声明活动并将主题作为AppCompat主题：
<application
...
android:theme="@style/Theme.AppCompat.Light" >

使用支持库中的操作栏版本。为此，您必须将支持库中的appcompat_v7导入您的工作区并在项目中引用它。之后只需将getActionBar（）更改为getSupportActionBar（），并希望它适用于较低版本。 您还必须扩展ActionBarActivity才能工作。
