我正在使用帶有5個選項卡的選項卡布局的應用程序。我需要在每個選項卡內導航多個片段,並在用戶再次選擇該選項卡時打開第一個片段。請幫幫我。帶多個片段的Tablayout選項卡
TabLayout tabLayout = (TabLayout) findViewById(R.id.tabLayout);
tabLayout.addTab(tabLayout.newTab().setIcon(R.drawable.scene_tab_selector));
tabLayout.addTab(tabLayout.newTab().setIcon(R.drawable.my_scene_tab_selector));
tabLayout.addTab(tabLayout.newTab().setIcon(R.drawable.conversation_tab_selector));
tabLayout.addTab(tabLayout.newTab().setIcon(R.drawable.notification_tab_selector));
tabLayout.addTab(tabLayout.newTab().setIcon(R.drawable.more_tab_selector));
tabLayout.setTabGravity(TabLayout.GRAVITY_FILL);
final ViewPager viewPager = (ViewPager) findViewById(R.id.pager);
final PagerAdaptor adapter = new PagerAdaptor
(getSupportFragmentManager(), tabLayout.getTabCount());
viewPager.setAdapter(adapter);
viewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));
tabLayout.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
@Override
public void onTabSelected(TabLayout.Tab tab) {
viewPager.setCurrentItem(tab.getPosition());
tab.getIcon().setColorFilter(Color.WHITE, PorterDuff.Mode.SRC_IN);
if(tab.getPosition()==4)
{
// pageTitleLabel.setText("My Profile");
}
}
@Override
public void onTabUnselected(TabLayout.Tab tab) {
tab.getIcon().setColorFilter(Color.parseColor("#a8a8a8"), PorterDuff.Mode.SRC_IN);
}
@Override
public void onTabReselected(TabLayout.Tab tab) {
}
});
我PagerAdaptor如下
public class PagerAdaptor extends FragmentStatePagerAdapter {
int mNumOfTabs;
public PagerAdaptor(FragmentManager fm, int NumOfTabs) {
super(fm);
this.mNumOfTabs = NumOfTabs;
}
@Override
public Fragment getItem(int position) {
switch (position) {
case 0:
Tab1ContainerFragment tab1 = new Tab1ContainerFragment();
return tab1;
case 1:
MyCuddllFragment tab2 = new MyCuddllFragment();
return tab2;
case 2:
// CuddllConversationFragment tab3 = new CuddllConversationFragment();
ConversationFragment conversationFragment = new ConversationFragment();
return conversationFragment;
case 3:
// CuddllNotificationsFragment tab4 = new CuddllNotificationsFragment();
Tab4ContainerFragment notificationPageFragment = new Tab4ContainerFragment();
return notificationPageFragment;
case 4:
MyProfileFragment tab5 = new MyProfileFragment();
return tab5;
default:
return null;
}
}
@Override
public int getCount() {
return mNumOfTabs;
}
}
請你能告訴你嘗試過這麼遠嗎?你也可以提到你在實現上面所述的問題 –
我試着查看尋呼機和尋呼機適配器。並在每個選項卡中加載第一個片段。但現在問題是在每個選項卡中遍歷片段 –
