In turn of data, I have checked that my photo url has already passed into Glide in the binding adapter. Why the image view is not visible under DialogFragment/BottomSheetDialogFragment?
My Dialog Layout xml with data binding
<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<data>
<variable
name="photoUrl"
type="String" />
</data>
<ImageView
android:id="#+id/imageView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:photoUrl='#{photoUrl}'
android:adjustViewBounds="true">
</ImageView>
</layout>
My BottomSheetDialogFragment.java
public class MyDialog extends BottomSheetDialogFragment {
#Nullable
#Override
public View onCreateView(#NonNull LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
View view = MyDialogBinding.inflate(inflater, container, false).getRoot();
return view;
}
#Override
public void onViewCreated(#NonNull View view, #Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
binding.setVariable(BR.photoUrl, MyDialogArgs.fromBundle(getArguments()).getPhotoUrl());
}
}
Remark:
I know there is a workaround method (i.e. Nest the image view in a frame layout or linear layout). I just curious why image view does not work as root view of Dialog.

I have a Video Detail Fragment which I want to behave as a bottom sheet behaviour, but unfortunately, the dialog is getting displayed at the centre of the screen. I am unable to figure out the exact problem in the code. Below I am attaching the code and the layout file, in regard to the same.
This is my Video Detail fragment:
public class VideoDetailsFragment extends BottomSheetDialogFragment {
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
AppCompatDialog dialog = new AppCompatDialog(getActivity());
dialog.setTitle(titleId);
return dialog;
}
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
View dialogView = inflater.inflate(R.layout.video_detail_fragment, container, false);
Button cancelButton = dialogView.findViewById(R.id.track_selection_dialog_cancel_button);
Button okButton = dialogView.findViewById(R.id.track_selection_dialog_ok_button);
return dialogView;
}
public static final class TrackSelectionViewFragment extends BottomSheetDialogFragment
implements TrackSelectionView.TrackSelectionListener {
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.exo_track_selection_dialog, container, /* attachToRoot= */ false);
TrackSelectionView trackSelectionView = rootView.findViewById(R.id.exo_track_selection_view);
trackSelectionView.setShowDisableOption(true);
trackSelectionView.setAllowMultipleOverrides(allowMultipleOverrides);
trackSelectionView.setAllowAdaptiveSelections(allowAdaptiveSelections);
trackSelectionView.init(mappedTrackInfo, rendererIndex, isDisabled, overrides, /* listener= */ this);
return rootView;
}
}
}
The xml file for video_detail_fragment:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="270dp"
android:visibility="visible"
app:behavior_hideable="true"
app:behavior_peekHeight="0dp"
app:layout_behavior="android.support.design.widget.BottomSheetBehavior"
>
<FrameLayout
android:id="#+id/child_fragment_container"
android:layout_width="match_parent"
android:layout_height="wrap_content"
/>
<LinearLayout
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="end">
</LinearLayout>
</LinearLayout>
I went through many posts but almost all the posts were showing the solution as setting the app attribute app:layout_behavior="android.support.design.widget.BottomSheetBehavior". But it's not working in my case. Kindly help me understand as to where I am doing wrong?
I would like to use a Tab/Fragment to show RecyclerView, but I don't know how to do it because the method of the Fragment class return a View, not a Reclycler View:
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
myFragmentView = inflater.inflate(R.layout.fragment_needs, container, false);
return myFragmentView;
}
The code of the fragment.xml is:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".NeedsFragment">
<FrameLayout
android:id="#+id/main_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentStart="true"
android:layout_alignParentTop="true"
android:layout_marginStart="0dp">
<android.support.v7.widget.RecyclerView
android:id="#+id/all_user_need_list"
android:layout_width="match_parent"
android:layout_height="match_parent">
</android.support.v7.widget.RecyclerView>
</FrameLayout>
</RelativeLayout>
Thank u.
First off, your onCreateView() method makes no sense:
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
myFragmentView = inflater.inflate(R.layout.fragment_needs, container, false);
return needsFragmentRecyclerView; //you should be returning myFragmentView here, not whatever needsFragmentRecyclerView is
}
Second, once you inflate your layout, just use findViewById():
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
myFragmentView = inflater.inflate(R.layout.fragment_needs, container, false);
RecyclerView recyclerView = myFragmentView.findViewById(R.id.all_user_need_list); //assign to a global variable if needed
return myFragmentView; //replaced with the proper variable
}
Alternatively, you can get the RecyclerView from anywhere in your Fragment, as long as it's called after onCreateView() with the following:
RecyclerView recyclerView = getView().findViewById(R.id.all_user_need_list);
You can return any type of view component and Custom view that is inherit from android.view class in onCreateView() method.
<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools">
<data>
<import type="com.demo.Model" />
<variable
name="model"
type="Model" />
</data>
<Textview
android:id="#+id/text"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:backgroundTint="#color/colorLableBg"
android:ems="10"
android:text="#={model.name}"
android:textCursorDrawable="#null/>
</layout>
Here is fragment
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
binding = DataBindingUtil.inflate(inflater, R.layout.fragment_authentication, container, false);
Model model = getModel()// get model return model data from server
binding.setModel(model);
binding.text.setText("This is demo")
}
I am getting data from api call and set the model.everything fine in case but when i set text its noting to change.
you need to do set that value after setting model otherwise value will be overwrite.
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
binding = DataBindingUtil.inflate(inflater, R.layout.fragment_authentication, container, false);
Model model = getModel()// get model return model data from server
binding.setModel(model);
binding.getModel.setName("this is demo");
}
You can try it:
Model model = getModel()// get model return model data from server
binding.setModel(model);
model.name.set("This is demo")
in your Model make sure name is:
public ObservableField<String> name = new ObservableField<>();
Hello I have a problem when I search the page tomorrow the process is successful but when I search the page today there is a problem , I used Fragment
the problem here : https://www.youtube.com/watch?v=FiHGME6i97I&feature=youtu.be
codes :
public void btn_search(View view) {
TextView txtexample = (TextView)findViewById(R.id.txtexample);
txtexample.setText("hello");
}
fragment days
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.user.weather.Fragment_days">
<!-- TODO: Update blank fragment layout -->
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/txtexample"
android:text="#string/hello_blank_fragment" />
</FrameLayout>
fragment days
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_days, container, false);
return v;
}
and fragment today and tomorrow are empty.
please help me , two weeks ago I was looking for a problem
Use the following (note two lines with txtexample):
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_days, container, false);
TextView txtexample = (TextView)v.findViewById(R.id.txtexample);
return v;
}
and
public void btn_search(View view) {
txtexample.setText("hello");
}
I have made a ListView on a Fragment.
public class MyList extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
view = inflater.inflate(R.layout.mylist, container, false);
return view;
}
}
This is the xml file where is the ListView:
<?xml version="1.0" encoding="utf-8"?>
<android.support.wearable.view.BoxInsetLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#ddffff"
xmlns:app="http://schemas.android.com/apk/res-auto"
>>
<android.support.wearable.view.WearableListView
android:id="#+id/mylist"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:scrollbars="none"></android.support.wearable.view.WearableListView>
</android.support.wearable.view.BoxInsetLayout>
When I run my app the listview does not appear. The entire screen is black. What I want to know is why this is happening.
Because of the typo in the following line:
xmlns:app="http://schemas.android.com/apk/res-auto"
>>
It cannot read >>. Android doesn't throw an exception for this typo
