该应用程序打开正常，我可以正常切换到每个标签，但是当尝试切换回已经打开的标签时，它会崩溃。我已经读过尝试更改它以扩展FragmentActivity而不是Fragment它可能会修复它，但是当我这样做时，我的onCreateView方法不起作用。
这是我的片段类：
public class WorkoutDetailFragment extends Fragment {
public WorkoutDetailFragment() {
}
@Override
public void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_blank, container, false);
RecyclerView rv = (RecyclerView) rootView.findViewById(R.id.rv_recycler_view);
rv.setHasFixedSize(true);
RvAdapter adapter = new RvAdapter(new String[] {"test 1", "test 2", "test 3", "test 4", "test 5"});
rv.setAdapter(adapter);
LinearLayoutManager llm = new LinearLayoutManager(getActivity());
rv.setLayoutManager(llm);
return rootView;
}
}
这是设置tablayout的类。虽然我不相信错误在那里，但我可能是错的。
public class WorkoutDaysActivity extends BaseActivity{
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.workout_days);
mToolBar = activateToolbar();
setUpNavigationDrawer();
// Get the ViewPager and set it's PagerAdapter so that it can display items
ViewPager viewPager = (ViewPager) findViewById(R.id.view_pager);
PagerAdapter pagerAdapter =
new PagerAdapter(getSupportFragmentManager(), WorkoutDaysActivity.this);
viewPager.setAdapter(pagerAdapter);
// Give the TabLayout the ViewPager
TabLayout tabLayout = (TabLayout) findViewById(R.id.tab_layout);
tabLayout.setupWithViewPager(viewPager);
// Iterate over all tabs and set the custom view
for (int i = 0; i < tabLayout.getTabCount(); i++) {
TabLayout.Tab tab = tabLayout.getTabAt(i);
tab.setCustomView(pagerAdapter.getTabView(i));
}
}
@Override
public void onResume() {
super.onResume();
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
class PagerAdapter extends FragmentPagerAdapter {
String tabTitles[] = new String[] { "Monday", "Wednesday", "Friday" };
Context context;
public PagerAdapter(FragmentManager fm, Context context) {
super(fm);
this.context = context;
}
@Override
public int getCount() {
return tabTitles.length;
}
@Override
public Fragment getItem(int position) {
switch (position) {
case 0:
return new WorkoutDetailFragment();
case 1:
return new WorkoutDetailFragment();
case 2:
return new WorkoutDetailFragment();
}
return null;
}
@Override
public CharSequence getPageTitle(int position) {
// Generate title based on item position
return tabTitles[position];
}
public View getTabView(int position) {
View tab = LayoutInflater.from(WorkoutDaysActivity.this).inflate(R.layout.custom_tab, null);
TextView tv = (TextView) tab.findViewById(R.id.custom_text);
tv.setText(tabTitles[position]);
return tab;
}
}}
感谢您的帮助！
