我使用ActionBarSherlock和Fragments设置了带有滑动选项卡的操作栏。
我想要每个选项卡都有不同的操作栏标题。如果我可以设置图像而不是标题,那就太好了,这样每个选项卡都会有不同的操作栏图像标题。
我会感激任何建议和教程链接!谢谢:)
以下是我的代码:
TabActivity.javapackage com.tptabs;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import com.actionbarsherlock.app.ActionBar;
import com.actionbarsherlock.app.SherlockFragmentActivity;
import android.support.v4.view.ViewPager;
public class TabActivity extends SherlockFragmentActivity {
private ViewPager mViewPager;
private TabAdapter mTabsAdapter;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mViewPager = new ViewPager(this);
mViewPager.setId(R.id.pager);
setContentView(mViewPager);
final ActionBar bar = getSupportActionBar();
bar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
mTabsAdapter = new TabAdapter(this, mViewPager);
mTabsAdapter.addTab(bar.newTab().setText("").setIcon(getResources().getDrawable(R.drawable.social_group)), JoinFragment.class, null);
mTabsAdapter.addTab(bar.newTab().setText("").setIcon(getResources().getDrawable(R.drawable.content_edit)), CreateFragment.class, null);
mTabsAdapter.addTab(bar.newTab().setText("").setIcon(getResources().getDrawable(R.drawable.location_web_site)), PlayFragment.class, null);
mTabsAdapter.addTab(bar.newTab().setText("").setIcon(getResources().getDrawable(R.drawable.collections_collection)), ResultFragment.class, null);
mTabsAdapter.addTab(bar.newTab().setText("").setIcon(getResources().getDrawable(R.drawable.device_access_accounts)), StoreFragment.class, null);
}
}
