我有一個包含4個操作欄選項卡的應用程序。雖然我導入了android.support.v7.app。 ActionBar庫，它只顯示在API 16設備中，但不顯示在API 10設備中。這裏有什麼解決方案？ 主要活動：API 10中的操作欄選項卡
import android.app.ActionBar;
import android.support.v4.app.FragmentManager;

import android.support.v4.view.ViewPager.OnPageChangeListener;
import android.support.v7.app.ActionBar.TabListener;
import android.support.v7.app.ActionBarActivity;
public class MainActivity extends ActionBarActivity {
public android.support.v7.app.ActionBar actionbar;
public ViewPager viewpager;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
actionbar = getSupportActionBar();
actionbar.setDisplayShowHomeEnabled(false);
actionbar.setDisplayShowTitleEnabled(false);
actionbar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
viewpager = (ViewPager) findViewById(R.id.pager);
FragmentManager fm = getSupportFragmentManager();
addPageChangeListener();
MyFragmentPagerAdapter fragmentPagerAdapter = new MyFragmentPagerAdapter(fm);
viewpager.setAdapter(fragmentPagerAdapter);
addActionBarListener();
}
public void addPageChangeListener() {

actionbar.setSelectedNavigationItem(position);
}
@Override

@Override

@Override

android.support.v7.app.ActionBar.Tab arg0,
android.support.v4.app.FragmentTransaction arg1) {

};
android.support.v7.app.ActionBar.Tab tab = actionbar.newTab()
.setTabListener(listener);
tab.setCustomView(R.layout.search);
actionbar.addTab(tab);
tab = actionbar.newTab().setTabListener(listener);
tab.setCustomView(R.layout.filter);
actionbar.addTab(tab);
tab = actionbar.newTab().setTabListener(listener);
tab.setCustomView(R.layout.favorite);
actionbar.addTab(tab);
tab = actionbar.newTab().setTabListener(listener);
tab.setCustomView(R.layout.info);
actionbar.addTab(tab);
}
}
MyPagerFragmentAdapter：
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
public class MyFragmentPagerAdapter extends FragmentPagerAdapter {
public final int PAGE_COUNT = 4;
public MyFragmentPagerAdapter(FragmentManager fm) {
super(fm);
}
@Override
public Fragment getItem(int i) {
// TODO Auto-generated method stub
Bundle data = new Bundle();
switch (i) {
case 0:
SearchFragment searchFragment = new SearchFragment();
return searchFragment;
case 1:
FilterFragment filterFragment = new FilterFragment();
return filterFragment;
case 2:
FavoriteFragment favoriteFragment = new FavoriteFragment();
return favoriteFragment;
case 3:
InfoFragment infoFragment = new InfoFragment();
return infoFragment;
}
return null;
}
@Override
public int getCount() {
return PAGE_COUNT;
}
}

在這裏發佈您的代碼... –
我們應該神奇地猜測錯誤？如果我告訴你「我的車壞了」，你能指出問題嗎？ –
我已添加代碼。我使用圖像而不是文本來定製選項卡視圖。 –
