how to Bind dynamic views using butterknife

i am creating the multiple dynamic views in android and my fragment using the layout of parent fragment and in child fragment i am creating the dynamic views but i am not able to bind those dynamic views using Butterknife.
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
this is the on create
// Inflate the layout for this fragment
View view = super.onCreateView(inflater, container, savedInstanceState); this.container.addView(inflater.inflate(R.layout.overall_sport_performance_row, null), 5);
i have one textview in the overall_sport_performance layout and i want to use that using butterknife

I don't really understand your solution, if your Fragment's view is overall_spot_performance.xml, do like this:
#BindView(R.id.your_text_view_id)
protected TextView textView;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = View.inflate(getContext(), R.layout.overall_sport_performance_row, null);
Butterknife.bind(this, view);
return view;
}
No need to bind the TextView dynamically. However if you still need to bind it dynamically, you can use findById method. I did not test it but should work like this:
View dynamicView = inflater.inflate(R.layout.overall_sport_performance_row, null);
this.container.addView(dynamicView, 5);
TextView textView = ButterKnife.findById(dynamicView, R.id.your_text_view_id);

getting a view using getResources()

I want to set text of a TextView that is inside a layout file,
I tried setContentView() but it isnt working since i am using fragments.
I tried using getResources().getLayout(R.layout.abc);
It returns null

I tried setContentView() but it isnt working since i am using
fragments
That's wrong. You have to override onCreateView and inflate and return the layout you want to show, and you can use onCreateView, and use its first parameter, View view, to call findViewById and access the widgets in your layout. You can read more here and here

inside fragment you can set view inside function onCreateView(), use below code
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle b) {
View view = (LinearLayout) inflater.inflate(R.layout.my_layout, container, false);
return view;
}
here my_layout should be the name of layout file,
now you can get view of it inside function onviewcreated()
public void onViewCreated(View view, Bundle savedInstanceState){
// here you can get your textview and set its value
}
thumbs up, if you find my answer correct

You can inflate your layout like this:
ViewGroup group = LayouInflate.from(context).inflate(R.layout.abc,null);
TextView tv = group.findViewById(R.id.xxx);

you have to inflate the layout through the onCreateView method and then return the View.
#Override
public View onCreateView(LayoutInflater inflater,ViewGroup container, Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.your_layout, container, false);
TextView yourTextView = (TextView)rootView.findViewById(R.id.yourTextViewId);
return rootView;
}

Fragments inheritance Android

Is it possible/recommanded to let different fragments inherit from each other in Android?
What would be the best way to initialize things that are already initialized in the superclass and add things to it ? (-> for example like the normal subclasses that use super() in their constructor and then initializing other objects )
I looked on the internet but i didn't found much information on this.
I know that it's possible to do return super.onCreateView() but you can't initialize other objects/views after that....
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState)
{
super.onCreateView()???
//initialize other objects here
//you have to return a view ...
}

Yes, it is allowed. Why not? For example, if you have a number of Fragments, that display lists, you could put all common methods in FragmentList, and then inherit other fragments, adding only unique methods or overriding the ones from super if needed.
But overriding onCreateView() could raise difficulties in layouts handling. In my recent project I instead created a method inflateFragment() in the super class as follows:
BaseFragment.java
protected View inflateFragment(int resId, LayoutInflater inflater, ViewGroup container) {
View view = inflater.inflate(resId, container, false);
FrameLayout layout = (FrameLayout)view.findViewById(R.id.fragment_layout);
/*
* Inflate shared layouts here
*/
. . .
setHasOptionsMenu(true);
return view;
}
Because of the structure, each and every fragment layout resource is wrapped in a FrameLayout with id = fragment_layout. But you're free to use LinearLayout or whatever parent view you need.
And then in inherited fragments:
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflateFragment(R.layout.my_fragment, inflater, container);
/*
* Do things related to this fragment
*/
...
return view;
}

Grid View in a fragment

I try to set up a grid view like in this tutorial : http://developer.android.com/guide/topics/ui/layout/gridview.html
But I want a fragment and setContentView in a fragment is not working. What I have to change to make it works ?
Thanks.

Override the onCreateView() method in your fragment like so:
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedState) {
return inflater.inflate(R.layout.fragment_layout, container, false);
}

Android animate view outside fragment is getting clipped

I have a view in a fragment. This fragment is within a FrameLayout. I want to animate this view moving outside the fragment borders. However, the view always get clipped when crossing the border. I have tried by setting android:clipChildren="false" and android:clipToPadding="false" to everything, but I can't get it to work.
Is this even possible to do?

I had the similar problem with fragments and put android:clipChildren="false" and android:clipToPadding="false" on all the levels in my hierarchy, but it was still not working. The trick that worked for me was to add this override in my fragment code:
#Override
public void onViewCreated(View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
ViewGroup vg = (ViewGroup) view;
vg.setClipChildren(false);
vg.setClipToPadding(false);
}
Hope this helps...
P.S. the credit should go to this answer

frangulyan You're missing the other bit of code from your credited answer. The below solution worked for me.
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
LinearLayout rootView = (LinearLayout) inflater.inflate(R.layout.fragment_main, container, false);
//This can be done in XML
rootView.setClipChildren(false);
rootView.setClipToPadding(false);
return rootView;
}
#Override
public void onViewCreated(View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
//This is the NoSaveStateFrameLayout - force it to not clip
FrameLayout frameLayout = (FrameLayout) getView();
frameLayout.setClipChildren(false);
frameLayout.setClipToPadding(false);
}

The answers already given by #frangulyan and #Barrie Galitzky were both on the right track, but I had to add this loop to setClipping false for all parents in the hierarchy before it would work properly
#Override
public void onViewCreated(View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
ViewGroup vg = (ViewGroup) view;
while(vg != null) {
vg.setClipChildren(false);
vg.setClipToPadding(false);
vg = vg.getParent() instanceof ViewGroup ? (ViewGroup) vg.getParent() : null;
}
}

I know this is a bit old, and correct answers have been given, but I wanted to add that you can do the same thing as frangulyan does inside onCreateView using the ViewGroup. I.e.:
#Override
public View onCreateView(LayoutInflater, ViewGroup container, Bundle savedInstanceState) {
container.setClipChildren(false);
container.setClipToPadding(false);
// Whatever other setup you like
return View;
}
