我在我的活动中添加了标签布局。一切正常,但标签指示器没有按预期显示。我正在添加下面的照片,以便您可以获得一个想法。我的意思是说,当我点击Overview(标签指示器显示在详细信息片段下方)时,反之亦然。
以下是XML代码(Activity_inventory_detail):
14:01:32 [http-bio-8085-exec-7] UsernamePasswordAuthenticationFilter - An internal error occurred while trying to authenticate the user.
org.springframework.security.authentication.InternalAuthenticationServiceException: [LDAP: error code 49 - 80090308: LdapErr: DSID-0C0903A8, comment: AcceptSecurityContext error, data 52e, v1db1
下面给出了Java代码(Inventory_deatil_Activity.java)(不能发布完整代码,因为它有很多行),只添加Tablayout和相关部分。这是我声明Tablayout的代码。
public class Inventory_detail_Activity extends AbstractKActivity实现了DetailsDataListener,View.OnClickListener, SimpleGestureFilter.SimpleGestureListener, ContentManager.PickContentListener {

这是我初始化Tablayout的地方。
public static final String TAG_LABEL_OVERVIEW = "Overview";
public static final String TAG_LABEL_DETAILS = "Detail";
InventoryItemsList inventoryItems;
protected int current_item_index = 0;
public List<InventoryItem> inventory_items_list = new ArrayList<>();
InventoryItem inventory_item;
private ViewPager viewPager;
private ViewPagerAdapter pagerAdapter;
TabLayout tabLayout;
以下是ViewPagerAdapter的代码
protected void init() {
final TabLayout tabLayout = (TabLayout)findViewById(R.id.tab_layout);
viewPager = (ViewPager) findViewById(R.id.pager_inventory_detail);
setupViewPager(viewPager);
tabLayout.setupWithViewPager(viewPager);
viewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));
tabLayout.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
@Override
public void onTabSelected(TabLayout.Tab tab) {
viewPager.setCurrentItem(tab.getPosition());
}
@Override
public void onTabUnselected(TabLayout.Tab tab) {
}
@Override
public void onTabReselected(TabLayout.Tab tab) {
}
});
[已编辑]:
这是AbstractActivity代码:
公共类AbstractKActivity扩展了AppCompatActivity {
class ViewPagerAdapter extends SmartFragmentStatePagerAdapter<ItemDetailAbstractFragment> {
//private final List<Fragment> mFragmentList = new ArrayList<>();
private final List<String> mFragmentTitleList = new ArrayList<>();
public ViewPagerAdapter(FragmentManager manager) {
super(manager);
}
@Override
public Fragment getItem(int position) {
ItemDetailAbstractFragment caf;
switch (position) {
case 0: // Fragment # 0 - This will show FirstFragment
caf = new ItemDetailOverviewFragment();
break;
case 1: // Fragment # 0 - This will show FirstFragment different title
caf = new ItemDetailDetailsFragment();
break;
default:
return null;
}
Bundle args = ActivityStateManager.getInstance().getActivityState(getLocalClassName());
if (args == null) {
args = new Bundle();
}
caf.setFlowItem(inventory_item);
if(current_item_index == -1) {
caf.setFlowItem(inventory_item);
caf.populateData();
}
return caf;
}
@Override
public int getCount() {
return 2;
}
public void addFragment(int position, String title) {
mFragmentTitleList.add(position, title);
}
@Override
public CharSequence getPageTitle(int position) {
return mFragmentTitleList.get(position);
}
}
@Override
public void onPause() {
Log.e("DEBUG", "onPause of ClientListTabactivity");
super.onPause();
// currentState.putSerializable("flowItem",inventory_item);
// ActivityStateManager.getInstance().updateActivityState(getLocalClassName(), currentState);
}
@Override
protected void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
// outState.putSerializable("flowItem",inventory_item);
// ActivityStateManager.getInstance().updateActivityState(getLocalClassName(), outState);
contentManager.onSaveInstanceState(outState);
}
@Override
protected void onRestoreInstanceState(Bundle savedInstanceState) {
super.onRestoreInstanceState(savedInstanceState);
contentManager.onRestoreInstanceState(savedInstanceState);
}
private void setupViewPager(ViewPager viewPager) {
pagerAdapter = new ViewPagerAdapter(getSupportFragmentManager());
pagerAdapter.addFragment(0, TAG_LABEL_OVERVIEW);
pagerAdapter.addFragment(1, TAG_LABEL_DETAILS);
viewPager.setAdapter(pagerAdapter);
//updateFragmentsForFlowItem();
}
}
答案 0 :(得分:1)
首先修改您的 CODE 。不要 return null;
。您应该返回默认片段。
<强>唐&#39;吨强>
case 1: // Fragment # 0 - This will show FirstFragment different title
caf = new ItemDetailDetailsFragment();
break;
default:
return null;
<强>不要强>
@Override
public Fragment getItem(int position) {
ItemDetailAbstractFragment caf;
switch (position) {
case 0: // Fragment # 0 - This will show FirstFragment
caf = new ItemDetailOverviewFragment();
break;
case 1: // Fragment # 0 - This will show FirstFragment different title
caf = new ItemDetailDetailsFragment();
break;
default:
return new ItemDetailOverviewFragment();
}
<强>其次强>
viewPager = (ViewPager) findViewById(R.id.pager_inventory_detail);
setupViewPager(viewPager);
tabLayout.setupWithViewPager(viewPager);
viewPager.setCurrentItem(0); // Declare this
修改强>
public void onTabSelected(TabLayout.Tab tab) {
tab.select();
}
