No View Found For Id ... For Fragment In A Dialog

I want show 2 tabs in a custom Dialog in an Activity, but I am getting the following error. Error: No view found for id 0x7f0f0134 (com.hiro.chatio:id/viewPage_theme) for fragment

Solution 1:

You're getting that Exception because the Activity's FragmentManager cannot find Views in a Dialog, as its layout is not attached to the Activity's hierarchy. In order to use Fragments in a Dialog, you'll have to use a DialogFragment, passing its child FragmentManager to the PagerAdapter to handle the transactions.

As with any regular Fragment, we can inflate the layout in onCreateView(), and set it up in onViewCreated(). We'll also override the onCreateDialog() method to modify the window settings there.

publicclassThemeDialogFragmentextendsDialogFragment {
    publicThemeDialogFragment() {}

    @Overridepublic View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        return inflater.inflate(R.layout.blog_theme_picker, container, false);
    }

    @OverridepublicvoidonViewCreated(View view, Bundle savedInstanceState) {
        ButtonpickColor= (Button) view.findViewById(R.id.pick_color_btn);
        Buttondefault_color= (Button) view.findViewById(R.id.default_color);
        TabLayoutmTabLayout= (TabLayout) view.findViewById(R.id.main_tabs_theme);
        CustomViewPagermViewPager= (CustomViewPager) view.findViewById(R.id.viewPage_theme);

        ThemePagerAdaptermThemePagerAdapter=newThemePagerAdapter(getChildFragmentManager());

        mViewPager.setAdapter(mThemePagerAdapter);
        mViewPager.setCurrentItem(0);
        mViewPager.setPagingEnabled(false);

        mTabLayout.setupWithViewPager(mViewPager);
    }

    @Overridepublic Dialog onCreateDialog(Bundle savedInstanceState) {
        Dialogd=super.onCreateDialog(savedInstanceState);
        d.getWindow().getAttributes().windowAnimations = R.style.SlideUpDialogAnimation;
        d.requestWindowFeature(Window.FEATURE_NO_TITLE);
        d.setCanceledOnTouchOutside(false);
        return d;
    }
}

You can see that everything you had in the onClick() method is now handled in the DialogFragment, and that method becomes simply:

pick_color.setOnClickListener(newView.OnClickListener() {
        @OverridepublicvoidonClick(View v) {
            newThemeDialogFragment().show(getSupportFragmentManager(), "theme");
        }
    }
);
