I want to have behaviour different for different Fragments. To implement such a fragment, return null in the onCreateView(). My MainActivity declaration in manifest is : Ĭan somebody help what I am doing wrong in this. Fragments can be used without defining a user interface. Replace getActivity ().getApplicationContext () with requireActivity () Problem : : Unable to add window token null is not valid is your activity running I tried to pop-up the DatePicker from this and itâs working fine till I put it in fragment. Same lines of code works perfectly when I execute them in onCreate() of MainActivity as shown : getWindow().setSoftInputMode(_INPUT_ADJUST_PAN) Ä«ut than the value is set for all four fragments. Solution 1 : Dialogs need an activity context. Problem is that it not working and I am not able to setSoftInputMode correctly and I can not prevent window getting resized. The first step to create back-sensitive fragments is to define the interface that we can call to notify particular fragments about back-press. in AndroidManifest.xml file as shown below : .Two things are required to be done for windowsSoftInputMode to work properly : First is add following flag : windowSoftInputMode'adjustResize'. Paolo Montalto Follow 2 min read Every android developer knows that he/she can set windowSoftInputMode inside AndroidManifest.xml as an attribute for each activity to manage the. Or ((MainActivity)getActivity()).getWindow().setSoftInputMode(_INPUT_ADJUST_PAN) Adding implementation for iBEK's comment. all state and member information, but is not attached to the window manager. So what I do is, on each Fragment's onViewCreated() method I execute the following line of code with changing LayoutParams flag: ((MainActivity)getActivity()).getWindow().setSoftInputMode(_INPUT_ADJUST_NOTHING) Configure the fragment code Update the class to extend DialogFragment rather than Fragment, which makes opening and closing the fragment easier: Add import. The function onSaveInstanceState is called before an activity may be killed. Out of these four Fragments on 3 Fragments(Let us say FragmentA, FragmentB, FragmentC), I want to set MainActivity's windowsoftinputmode() to SOFT_INPUT_ADJUST_PAN so that window can resize.Īnd on one Fragment()let us say FragmentD), I want to set MainActivity's windowsoftinputmode() to SOFT_INPUT_ADJUST_NOTHING. From this activity I instantiate 4 fragments(Let us say FragmentA, FragmentB, FragmentC, FragmentD. You may know that its pretty simple to do so at runtime by calling the (mode). I have a requirement in which I have one MainActivity. Setting the value in AndroidManifest.xml.
