I'm trying to set on click method in my project but, I can't connect my layout to the given fragment. When you press the icon of Instagram it should open persons Instagram but it only crashes.
Fragment code:
public class SupportFragment extends Fragment {
#Nullable
ImageView vedoIg;
public View onCreateView(#NonNull LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_support,container,false);
vedoIg = v.findViewById(R.id.vedo_ig);
vedoIg.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Uri uri = Uri.parse("http://instagram.com/v");
Intent instagram = new Intent(Intent.ACTION_VIEW, uri);
instagram.setPackage("com.instagram.android");
try {
startActivity(instagram);
}
catch (Exception e){
startActivity(new Intent(Intent.ACTION_VIEW,Uri.parse("http://instagram.com/_u/v")));
}
}
});
return inflater.inflate(R.layout.fragment_support,container,false);
}
}
Layout folder:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:tools="http://schemas.android.com/tools"
android:background="#drawable/pozadina"
tools:context=".SupportFragment">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_marginTop="40dp"
android:text="Contact us: "
android:textColor="#ffffff"
android:textSize="30dp"
android:textStyle="bold" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_marginTop="90dp"
android:text="Vedo"
android:textColor="#ffffff"
android:textSize="30dp"
android:textStyle="bold" />
<ImageView
android:id="#+id/vedo_ig"
android:layout_width="72dp"
android:layout_height="48dp"
android:layout_marginLeft="40dp"
android:layout_marginTop="150dp"
app:srcCompat="#drawable/w_instagram"/>
Any tip would mean the world. Thanks in advance :D <3
This bit of code is problematic:
public View onCreateView(#NonNull LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_support,container,false);
vedoIg = v.findViewById(R.id.vedo_ig);
// ...
return inflater.inflate(R.layout.fragment_support,container,false);
}
In the first line, you're inflating one copy of a view... but then you return a different copy of that same view. This means that what the user sees won't match the view you've been searching in and setting click listeners on.
Change the last line to return v to fix this issue.
please try https://www.instagram.com/v/ you must change http with https

I'd like to be able to set a View.OnclickListener to an ImageView inside a page (fragment) of my ViewPager, I don't want to click on the whole page of my ViewPager, I just want to be able to click on a specifig ImageView. I followed these questions (onClick not triggered on LinearLayout with child, How to set OnClickListener in ViewPager
) but they did not help me. This is my actual code:
MyPageFragment.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="240dp"
android:layout_marginLeft="16dp"
android:layout_marginRight="16dp"
android:focusableInTouchMode="true"
android:id="#+id/container_linear"
android:gravity="center"
android:orientation="vertical">
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:scaleType="centerCrop" />
</LinearLayout>
</LinearLayout>
MyActivity.xml
<android.support.v4.view.ViewPager
android:id="#+id/product_view_pager"
android:layout_width="match_parent"
android:layout_height="240dp"
android:layout_marginLeft="4dp"
android:layout_marginRight="4dp"
android:gravity="center"
android:overScrollMode="never" />
MyFragment.class (where I'm binding the views using Butterknife)
#BindView(R.id.container_linear)
LinearLayout mContainer;
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container,
#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
View mRootView = inflater.inflate(R.layout.my_layout, container, false);
ButterKnife.bind(this, mRootView);
mContainer.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Log.d("Test", "Clicked!");
}
});
}
Thanks for your support.
One thing to consider would be moving your OnClickListener to the parent LinearLayout you're setting as clickable and seeing if that helps.
Another thing is adding android:focusableInTouchMode="true" to the view you're attaching your OnClickListener to.
Other than that, you might want to share the code for registering the OnClickListener so we can investigate other possible errors.
If I understand correctly you want to click on the image view insideMyPageFragment.xml. This is simple but you need to give ID to the ImageView and refer it in your onCreateView method like you do for LinearLayout and then use onClickListener on that image.
So with recent conversation it seems that in linear layout you need to remove line clickable="false"
Basically that has blocked all the clicks on its children, thus that linear layout as well as the imageview clicks are not working for you. See this code I removed that line. Hope this works
Follow this code.
MyPageFragment.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:duplicateParentState="true"
android:orientation="vertical">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="240dp"
android:layout_marginLeft="16dp"
android:layout_marginRight="16dp"
android:focusableInTouchMode="true"
android:id="#+id/container_linear"
android:gravity="center"
android:orientation="vertical">
<--you need to give ID to the view to be able to
perform events on them specifically.-->
<ImageView
android:id="#+id/my_awesome_image"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:scaleType="centerCrop" />
</LinearLayout>
Now in your MyFragment.class
#BindView(R.id.container_linear)
LinearLayout mContainer;
//declare with butterknife
#BindView(R.id.my_awesome_image)
ImageView myAwesomeImage;
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container,
#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
View mRootView = inflater.inflate(R.layout.my_layout, container, false);
ButterKnife.bind(this, mRootView);
//you set click listener previously on entire linear layout instead of imageview
//that's why it was not reflecting on imageview click.
myAwesomeImage.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Log.d(TAG , "Awesome Imageview clicked!");
}
});
}
I solved this issue using the following chunk of code:
#Override
public void onViewCreated(View view, Bundle savedInstanceState){
view.setOnClickListener(new OnClickListener(){
public void onClick(View v){
/* Do as you please here. */
}
});
}

I want to change from layout 1 to layout 2, after rotate still keep content. Can somebody show me how to do that?
from this: https://www.dropbox.com/sc/y2nyrzard859hf2/AAD0qVjWoLzKcnQV9a4FTQi_a
to this: https://www.dropbox.com/sc/29hhlbfm31cfs0j/AADCWsFNzD7DKHx4q9i2FlbDa
this is my code but seem like it didn't work
if(config.orientation == Configuration.ORIENTATION_LANDSCAPE) {
setContentView(R.layout.activity_create_bill3);

fragmentTransaction.commit();
I using 2 diffent layout, it has a same view but one in horizontal and another in vertical, when rotate, fragment_product still keep content, but fragment_product_chosen are disappear.
You should have 3 clases:
FragmentMain
FragmentSide
MainActivity
click here to see your layout folder
Code in your MainActivity Class:
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
}
Code in your FragmentMain Class:
public class FragmentMain extends Fragment{
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
return inflater.inflate(R.layout.fragment_main, container, false);
}
}
Code in your FragmentSide Class:
public class FragmentSide extends Fragment {
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
return inflater.inflate(R.layout.fragment_side, container, false);
}
}
Then in your activity_main.xml:
<fragment
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/fragment_main"
android:layout_marginTop="230dp"
class="au.com.example.multi_fragments.FragmentMain" />
<fragment
android:layout_width="match_parent"
android:layout_height="220dp"
android:id="#+id/fragment_side"
class="au.com.example.multi_fragments.FragmentSide" />
/>
same way in your activity_main.xml(land):
<fragment
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginLeft="250dp"
android:id="#+id/fragment_main"
class="au.com.example.multi_fragments.FragmentMain" />
<fragment
android:layout_width="240dp"
android:layout_height="match_parent"
android:id="#+id/fragment_side"
class="au.com.example.multi_fragments.FragmentSide" />
in your fragment_main.xml:
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="View 2"
android:textSize="20sp"
android:padding="20dp"
android:textStyle="bold"
android:id="#+id/textViewMain" />
In your fragment_side.xml:
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="View 1"
android:textSize="20sp"
android:padding="20dp"
android:textStyle="bold"
android:id="#+id/textViewMain" />

I hope this solution is the one you want. Good luck :)
To have different layouts for landscape and portrait modes, create two folders under the res folder: layout and layout-land. All XML files should have the same names in both folders. For more details, read Designing for Multiple Screens. Even though this article is for different screen sizes, the techniques apply to different device orientations as well.
As for saving and restoring data, this is the same as destroying the activity without an orientation change.
I have a problem when declaring a button.
I will try to explain as specific as possible.
In my main Layout I have a Fragment containing a secondary Layout. In which I have several buttons.
My intention is that my main fichero.java to declare the buttons within the fragment.
Here we put the main Layout:
<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"
android:baselineAligned="false">
<fragment
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:name="josejuansosarodriguez.radioecca.conocecanarias.TrueoFalseFragment"
android:id="#+id/fragmentTrueFalse"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/Grp1"
android:id="#+id/textGrp1"
android:textSize="25sp"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="5dp"/>
<fragment
android:layout_width="fill_parent"
android:layout_height="450dp"
android:name="josejuansosarodriguez.radioecca.conocecanarias.Grp1FragmentP1"
android:id="#+id/fragmetaskGRP1"
android:layout_below="#+id/textGrp1"
android:layout_centerHorizontal="true"
android:layout_marginTop="5dp" />
</RelativeLayout>
Here we put the secondary Layout that has the buttons:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent" android:layout_height="match_parent"
android:id="#+id/fragment_TrueorFalse">
<Button
android:layout_width="120sp"
android:layout_height="wrap_content"
android:textAllCaps="false"
android:text="#string/buttontrue"
android:id="#+id/buttontrue"
android:layout_marginLeft="40dp"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true" />
<Button
android:layout_width="120sp"
android:layout_height="wrap_content"
android:textAllCaps="false"
android:text="#string/buttonfalse"
android:id="#+id/buttonfalse"
android:layout_marginRight="40dp"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true" />
</RelativeLayout>
And here I leave the my main activity:
public class Grp1Fragment extends Fragment {
private Button buttonTrue;
private Button buttonFalse;
private Button buttonNextAsk;
private View view;
public Grp1Fragment() {
// Required empty public constructor
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
buttonTrue = (Button) view.findViewById(R.id.buttontrue);
buttonTrue.setOnClickListener(this);
// Inflate the layout for this fragment
view = inflater.inflate(R.layout.fragment_grp1, container, false);
return view;
}
My problem I find in the following line:
buttonTrue.setOnClickListener (this);
The message reads: View can not be in Applied to josejuansosarodriguez.radioecca.conocecanarias.Grp1Fragment
I hope I have spread far.
Thank you very much for everything, this forum is amazing.
Try this:
Note that you have to FIRST inflate the layout to make accesible the widgets of the layout.
Then you can "bind" the widgets, and finallly in this case, set the listeners to the buttons.
I set you a Log, if you need change it to Toast, or code
public class Grp1Fragment extends Fragment {
private Button buttonTrue;
private Button buttonFalse;
private Button buttonNextAsk;
private View view;
public Grp1Fragment() {
// Required empty public constructor
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
view = inflater.inflate(R.layout.fragment_grp1, container, false);
//Declare your widgets (Buttons)
buttonTrue = (Button) view.findViewById(R.id.buttontrue);
buttonFalse = (Button) view.findViewById(R.id.buttonfalse);
//Set the Listeners
buttonTrue.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
//Toast or Log, or whateber you need
Log.d("Fragment1" , "Button: True");
}
});
buttonFalse.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
//Toast or Log, or whateber you need
Log.d("Fragment1" , "Button: FAlse");
}
});
//return the view
return view;
}
void setOnClickListener(View.OnClickListener l)
requires a OnClickListener, which Grp1Fragment is not.
Use something like
buttonTrue.setOnClickListener(new View.OnClickListener() {
void onClick(View v) {
... // reaction on the button
}
});
I have a fragment inside the main activity.The fragment contains an image view.My aim is to divide the image view into 3 different buttons.So ,i set up a linear layout which overlaps the image view and it contains 3 clickable views with equal gravity.
In the fragment i implements OnClickListener ,as this-
public class FragmentHomeMenu extends Fragment implements OnClickListener {
View view;
Context activity_context;
View button_search_1;
View button_search_2;
View button_search_3;
...plenty of other stuff
public FragmentHomeMenu() {
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
view = inflater.inflate(R.layout.fragment_home_menu, container, false);
activity_context = getActivity().getApplicationContext();
button_search_1 = (View) view
.findViewById(R.id.button_search_1);
button_search_1.setOnClickListener(this);
button_search_2 = (View) view.findViewById(R.id.button_search_2);
button_search_2.setOnClickListener(this);
button_search_3 = (View) view.findViewById(R.id.button_search_3);
button_search_3.setOnClickListener(this);
....plenty of other stuff
return view;
}
#Override
public void onAttach(Activity activity) {
super.onAttach(activity);
activity_context = activity.getApplicationContext();
}
#Override
public void onClick(View v) {
Log.w("", "some thing was clicked");
switch (v.getId()) {
case R.id.button_search_2:
dostuff1();//stuff1 is not happening in android 4.3,but works on 4.0
break;
case R.id.button_search_1:
dostuff2();//stuff2 is not happening in android 4.3,but works on 4.0
break;
......plenty of other stuff
}
I checked for the problem on plenty of places but could not find solution.My code works perfect on
devices with android 4.0 but in 4.3 nothing happens when i click on the image.
here is the xml-
.......
<ImageView
android:id="#+id/imageview_searchbar"
android:layout_width="370dp"
android:layout_height="wrap_content"
android:layout_below="#+id/rltv1"
android:layout_centerHorizontal="true"
android:layout_marginTop="5dp"
android:adjustViewBounds="true"
android:clickable="true"
android:src="#drawable/search_bar" />
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottom="#+id/imageview_searchbar"
android:layout_alignLeft="#+id/imageview_searchbar"
android:layout_alignRight="#id/imageview_searchbar"
android:layout_alignTop="#+id/imageview_searchbar"
android:orientation="horizontal"
android:weightSum="21" >
<View
android:id="#+id/button_search_1"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="7"
android:clickable="true" />
<View
android:id="#+id/button_search_2"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="7"
android:clickable="true" />
<View
android:id="#+id/button_search_3"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="7"
android:clickable="true" />
</LinearLayout>
.......lots of other stuff
I figured it out-I just had to bring the linear layout(containing buttons) to the front.
It got hidden under the image when using android 4.3 so i did this-
LinearLayout search_bar_buttons = (LinearLayout) view.findViewById(R.id.ll_search_bar_buttons);
search_bar_buttons.bringToFront();
Thank you guys for helping
I have a ListView in a Fragment containing also some other UI-Elements. Everything works until I call setAdapter on the ListView. In that moment I can debug that the ListView is filled with the elements but immmediately after the whole fragment disappears (including the other UI-Elements). If I set the Adapter 0,1 seconds later, everything works.
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
mView = inflater.inflate(R.layout.fragment_listview, null);
mListView = (ListView)mView.findViewById(R.id.list_items);
TextView emptyView = (TextView)mView.findViewById(R.id.text_empty);
mListView.setEmptyView(emptyView);
final Handler handler = new Handler();
handler.postDelayed(new Runnable() {
#Override
public void run() {
// this is the only work around to not make the list view disappear
loadContacts();
}
}, 100);
// if I call loadContacts() here, the Fragment disappears
mListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Person p = mContacts.get(position);
if (pickerInterface != null) {
pickerInterface.pickedContact(p);
}
}
});
return mView;
}
public void loadContacts() {
mContacts = ContactsDataSource.getAllPhoneContacts(getActivity(), true);
mAdapter = new ContactsAdapter(getActivity());
mAdapter.mContacts = mContacts;
mAdapter.isPlainList = true;
// after the following line the Fragment is filled and then immediately disappears
mListView.setAdapter(mAdapter);
}
the ContactsAdapter is very simple:
public class ContactsAdapter extends BaseAdapter {
public List<Person> mContacts = new ArrayList<Person>();
public Activity context;
// Constructor
public ContactsAdapter(Activity c){
context = c;
}
#Override
public int getCount() {
return mContacts.size();
}
public Person getItem(int position){
return mContacts.get(position);
}
#Override
public boolean isEmpty()
{
return mContacts.size() == 0;
}
#Override
public long getItemId(int position) {
return position;
}
#SuppressLint("InflateParams")
public View getView(int position, View convertView, ViewGroup viewGroup) {
if (convertView == null) {
LayoutInflater inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(R.layout.list_item_contact, null);
}
Person person = mContacts.get(position);
TextView tvName = (TextView) convertView.findViewById(R.id.text_name);
tvName.setText(person.getDisplayName());
return convertView;
}
}
I have spent hours debugging and searching for reasons and have no clue. Thanks for any idea.

Where did you initialize your "mListView"?
The time that fragment inflated is "onCreateView()" and general way of getting view instances from layout is done on this method. like below
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_one, null);
mListView = (ListView)v.findViewById(R.id.list_items);
...
return v;
}
How about trying to initalize your views(ListViews, and others) in "onCreateView"?
I think that the problem is caused from getting view instances before fragment is inflated.
Not sure what your problem is. May be with the custom super class. Otherwise, wild guess here, but try inflating your view like this.
mView = inflater.inflate(R.layout.fragment_listview, container, false);
First of all, storing a context object can be dangerous and should therefore be avoided if possible... You can easily get rid of it in your adapter with following steps (that hopefully also solves your problem):
--> try following constructor for your adapter:
public ContactsAdapter(Context c){
super(c, R.layout.yourlayout_listitem_name;
}
--> and adjust the getView-method to use something like:
final View rowView = View.inflate(viewGroup.getContext(), R.layout.yourlayout_listitem_name, null);
instead of the inflater-if-block. then always return rowView at the end.
and just to be sure I would remove the overriden-method:
#Override
public long getItemId(int position) {
return position;
}
since it is not doing anything useful anyway ;-)
Thank you for all your support. By removing all code and re-assembling step by step I foundt the reason. Just in case someone runs in the same problem one day.
I had an OnScrollListener on the ListView declared in the superclass. In the OnScrollListener I was hiding the navigation Arrows on demand with Visibility.GONE. Even if the NavigationArrows did not affect the layout of the ListView this was the problem. By setting Visibility.INVISIBLE everything works fine. I guess this is related to some re-drawing-issue of the whole layout that does not work.
