Fragment view is not outputting

Fragment view is not outputting - android

I have a fragment called TabFragment, which contains an ImageAdapter. Now the ImageAdapter will create an imageView which I attached an onclick listener to it. Once the imageView is clicked I would like to open the DetailsFragment fragment. However open pressing upon the imageView, the Toast messages are shown meaning that the specific fragments are accessed, but the actual view of the fragment is not.
ImageAdapter class
public class ImageAdapter extends BaseAdapter {
private Context mContext;
private FragmentManager fragmentManager;
public ImageAdapter(Context c,FragmentManager fm) {
mContext = c;
fragmentManager = fm;
}
public int getCount() {
return mThumbIds.length;
}
public Object getItem(int position) {
return null;
}
public long getItemId(int position) {
return 0;
}
// create a new ImageView for each item referenced by the Adapter
public View getView(final int position, final View convertView, final ViewGroup parent)
{
ImageView imageView;
if(convertView == null)
{
imageView = new ImageView(mContext);
imageView.setLayoutParams(new GridView.LayoutParams(300,300));
imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
imageView.setPadding(8,8,8,8);
}
else
{
imageView = (ImageView) convertView;
}
imageView.setImageURI(mThumbIds[position]);
//check for tap
if(imageView.getDrawable() != null)
{
imageView.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Toast.makeText(mContext, "clicked", Toast.LENGTH_SHORT).show();
Fragment detailsFragment = new DetailsFragment();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.add(R.id.container,detailsFragment);
fragmentTransaction.addToBackStack(null);
fragmentTransaction.commit();
}
});
}
return imageView;
}
private Uri[] mThumbIds = new Uri[20];
public void setUriArr(Uri[] uriArr){
this.mThumbIds = uriArr;
}
}
DetailsFragment Class
public class DetailsFragment extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.fragment_details, container, false);
Toast.makeText(getContext(), "entered fragment", Toast.LENGTH_SHORT).show();
return view;
}
}
TabFragment fragment [just in case]
public class TabFragment extends Fragment{
View rootView;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
rootView = inflater.inflate(R.layout.fragment_tab, container, false);
LoadGridView(rootView);
return rootView;
}
#Override
public void onResume() {
super.onResume();
LoadGridView(rootView);
}
public void LoadGridView(View v){
GridView gridview = (GridView) v.findViewById(R.id.grdvwImages);
ImageAdapter ia = new ImageAdapter(getActivity(),getFragmentManager());
int i = 0;
Uri[] imageArray = new Uri[20];
int pos = getArguments().getInt("position", 0);
//DeleteAll();
List<GalleryModel> news = GetNewsArticles(pos);
if(news.size() != 0){
for(GalleryModel n:news){
imageArray[i] = Uri.parse(n.imageDir);
i++;
}
ia.setUriArr(imageArray);
}
gridview.setAdapter(ia);
}
public List<GalleryModel> GetNewsArticles(int position){
return new Select()
.from(GalleryModel.class)
.where("Section = ?", position)
.execute();
}
public void DeleteAll()
{
new Delete().from(GalleryModel.class).execute();
}
}

replace instead of add
Fragment detailsFragment = new DetailsFragment();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.replace(R.id.container,detailsFragment);
fragmentTransaction.addToBackStack(null);
fragmentTransaction.commit();
EDIT: remove absolute x and y from relativelayout
<RelativeLayout
android:background="#android:color/white"
android:layout_width="395dp"
android:layout_height="587dp">
and check your version of constraint-layout in gradle
EDIT2: organize your code
create click listener for the image in the imageadapter like this:
public class ImageAdapter extends BaseAdapter {
private Context mContext;
private FragmentManager fragmentManager;
private ImageAdapterClick imageAdapterListener;
public interface ImageAdapterClick {
void isClicked();
}
public ImageAdapter(Context c,FragmentManager fm, ImageAdapterClick imageAdapterListener) {
mContext = c;
fragmentManager = fm;
this.imageAdapterListener = imageAdapterListener;
}
then change local listener in the getView method
imageView.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
imageAdapterListener.isClicked();
}
});
then in your TabFragment change the adapter in the way which would call that details fragment
ImageAdapter ia = new ImageAdapter(getActivity(),getFragmentManager(), new
ImageAdapter.ImageAdapterClick (){
#Override
public void isClicked() {
Fragment detailsFragment = new DetailsFragment();
FragmentTransaction fragmentTransaction =
fragmentManager.beginTransaction();
fragmentTransaction.replace(R.id.container,detailsFragment);
fragmentTransaction.addToBackStack(null);
fragmentTransaction.commit();
}
});

Replace fragmentA with fragmentB issue

I have a image in the main activity and when this image is clicked i want to show the fragmentA that has a list view.
When a item of this listView is clicked i want to replace the fragmentA by the fragmentB that has a textview, and I want to show in this textview the text associated to the clicked list item.
So in main activity I have this:
public class MainActivity extends AppCompatActivity implements Listener{
private ImageView img;
private String text;
FragmentManager fragmentManager;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
fragmentManager = getFragmentManager();
img = (ImageView) findViewById(R.id.imageView);
}
public void AddFragmentA(View view) {
FragmentA fragmentA = new FragmentA();
FragmentTransaction transaction = fragmentManager.beginTransaction();
transaction.add(R.id.containerFragmentA, new FragmentA(), "fragA");
transaction.commit();
}
public void AddFragmentB() {
FragmentB fragment = new FragmentB();
FragmentTransaction transaction = fragmentManager.beginTransaction();
transaction.add(R.id.containerFragmentB, new FragmentA(), "fragB");
transaction.commit();
}
#Override
public void addText(String text) {
this.text = text;
Toast.makeText(this, "Text received in Activity:" +text, Toast.LENGTH_SHORT).show();
sendDataToFragmentB();
}
public void sendDataToFragmentB(){
FragmentB fragmentB = (FragmentB) fragmentManager.findFragmentByTag("fragB");
fragmentB.addText(text);
}
}
Note: The toast in addText() appears with the correct text at this point, so the text of the list view is received in Activity with success.
Question: Now how to replace fragmentA with fragmentB and show the textview with the received text in the activity instead of showing the listview of the fragmentA?
Below is all the complete example.
FragmentA class:
public class FragmentA extends Fragment{
private ListView listItems;
private String[] items = {
"item1",
"item2",
"item3",
"item4"
};
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment, container, false);
return view;
}
#Override
public void onActivityCreated(#Nullable Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
listItems = (ListView) getView().findViewById(R.id.listviewInFragment);
ArrayAdapter<String> adapter =
new ArrayAdapter<String>(getActivity().getApplicationContext(),
android.R.layout.simple_list_item_1, android.R.id.text1, items);
listItems.setAdapter(adapter);
listItems.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
int positionCode = i;
String clickedValue = (String) adapterView.getItemAtPosition(i);
Listener listener = (Listener) getActivity();
listener.addText(clickedValue);
}
});
}
}
FramentB:
public class FragmentB extends Fragment {
private TextView tv;
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_b, container, false);
tv = (TextView) getView().findViewById(R.id.textView);
return view;
}
public void addText(String text) {
String result = text;
tv.setText(result);
}
}

you are placing fragment A in below function instead of fragment B
public void AddFragmentB() {
FragmentB fragment = new FragmentB();
FragmentTransaction transaction = fragmentManager.beginTransaction();
transaction.add(R.id.containerFragmentB, new FragmentA(), "fragB");
transaction.commit();
}
it should be
public void AddFragmentB() {
FragmentB fragment = new FragmentB();
FragmentTransaction transaction = fragmentManager.beginTransaction();
transaction.replace(R.id.containerFragmentB, new FragmentB(), "fragB");
transaction.commit();
}
if you want to replace a fragment with another just use the same container
don't create separate (R.id.containerFragmentB, R.id.containerFragmentA) container.

You need to change your
public void AddFragmentA(View view) {
FragmentA fragmentA = new FragmentA();
FragmentTransaction transaction = fragmentManager.beginTransaction();
transaction.add(R.id.containerFragmentA, new FragmentA(), "fragA");
transaction.commit();
}
public void AddFragmentB() {
FragmentB fragment = new FragmentB();
FragmentTransaction transaction = fragmentManager.beginTransaction();
transaction.add(R.id.containerFragmentB, new FragmentA(), "fragB");
transaction.commit();
}
to
public void AddFragmentA(View view) {
FragmentA fragmentA = new FragmentA();
FragmentTransaction transaction = fragmentManager.beginTransaction();
transaction.add(R.id.container, fragmentA , "fragA");
transaction.commit();
}
public void AddFragmentB() {
FragmentB fragment = new FragmentB();
FragmentTransaction transaction = fragmentManager.beginTransaction();
transaction.add(R.id.container, fragment, "fragB");
transaction.commit();
}
and activity_main.xml should be

How to add fragment int the right item when tap on the gridview item

Here is my CategoryFragment:
public class CategoryFragment extends Fragment implements CategoriesItemsAdapter.CategoriesDelegate {
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
mView = inflater.inflate(R.layout.fragment_budget,container,false);
mSavedInstanceState= savedInstanceState;
return mView;
}
private void setGridViewAdapter(ArrayList<String> texts, ArrayList<Integer> icons){
mCategories = (GridView) mView.findViewById(R.id.categories);
CategoriesItemsAdapter adapter = new CategoriesItemsAdapter(getActivity(),texts,icons);
adapter.CategoriesDelegate = this;
mCategories.setAdapter(adapter);
}
#Override
public void categoriesDelegate() {
MainActivity activity = (MainActivity) getActivity();
FragmentManager manager = activity.getSupportFragmentManager();
FragmentTransaction transaction = manager.beginTransaction();
if (mSavedInstanceState == null) {
transaction.replace(R.id.categories_frame, new CategoriesFragment());
}
transaction.addToBackStack(null);
transaction.commit();
}
}
Here is my CategoriesItemsAdapter:
public class CategoriesItemsAdapter extends BaseAdapter implements View.OnClickListener {
#Override
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
convertView = mInflater.inflate(R.layout.item_categories, parent, false);

ImageView icon = (ImageView) convertView.findViewById(R.id.icon);
TextView text = (TextView) convertView.findViewById(R.id.category_name);
text.setText(mTexts.get(position));
icon.setImageResource(mIcons.get(position));
icon.setOnClickListener(this);
return convertView;
}
#Override
public void onClick(View v) {
if (CategoriesDelegate != null) {
CategoriesDelegate.categoriesDelegate();
}
}
public interface CategoriesDelegate {
void categoriesDelegate();
}
}
I want to open a fragment when I click on the a grid view item. I can open a fragment but the fragment is opening in the wrong place. Fragment always opens in the first item. Which grid view item I clicked on in that grid view item,fragment should be opened. How I can solve this problem?

Get view for button click on the Fragment of the ViewPager

I have successfully set up the a FragmentActivity with FragementPagerAdapter associated with ViewPager to implement two tabbed application .
One of the Tabs namely "Wave" has a text view and a button . All I want is call textview.setText method via the onClick method of button described by its xml attribute .
I do not know where should I initialize my TextView or Button , how can I get the context of Wave tab and where should I write onclick method-
public class InformationShow extends FragmentActivity {
XMLdata dataObject;
ViewPager viewPager;
PagerAdapter adpt;
Fragment temp;
TextView tv;
Button bt;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.fragment_main);
viewPager=(ViewPager)findViewById(R.id.pager);
adpt = new PagerAdapter(getSupportFragmentManager());
viewPager.setAdapter(adpt);
// temp=adpt.fg.findFragmentById((int)adpt.getItemId(1));
tv=(TextView)findViewById(R.id.graphWaveTextView);
bt = (Button)findViewById(R.id.button1);
}
public void changeText(View v){
tv.setText("It worked ");
}
Adapter Class
public class PagerAdapter extends FragmentPagerAdapter {
int count = 2;
CharSequence namme[] = {"Temperature","Wave"};
XMLdata data;
FragmentManager fg;
public PagerAdapter(FragmentManager fragmentManager ){
super(fragmentManager);
this.fg = fragmentManager;
}
Context context;
#Override
public Fragment getItem(int arg0) {
switch (arg0){
case 0:{
TemperatureGraphFrag temp = new TemperatureGraphFrag();
return temp;
}
case 1:{WaveHeightGraphFrag wave = new WaveHeightGraphFrag();
return wave;
}
}
return null;
}
#Override
public int getCount() {
return 2;
}
#Override
public CharSequence getPageTitle(int position) {
return namme[position];
}
}

public class TemperatureGraphFrag extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.graph_t, container, false);
return view;
}
}
public class WaveHeightGraphFrag extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,

View view = inflater.inflate(R.layout.graph_sig_wave_height, container, false);
return view;
}

Add the following method to your WaveHeightGraphFrag class:
#Override
public void onViewCreated(View view, Bundle savedInstanceState){
final TextView t = (TextView) view.findViewById(R.id.graphWaveTextView);
Button b = (Button) view.findViewById(R.id.button1);
b.setOnClickListener(new OnClickListener(){
#Override
public void onClick(View v){
t.setText("It worked ");
}
});
}
This is what you want.

How to use same fragment in a viewPager?

I develope currently a small sample app with fragments and a viewPager. The viewPager shows 3 pages. In each page i instantiate a fragment of the same type. The fragment contains a textView and a button. On button click I want to replace the current fragment with another one. Now my problem is, no matter which button I press only the fragment of page 1 gets replaced. I dont know what I have to do in my pageAdapter class but I guess it has to do with using the same fragment and layout. I think I have to make sure, that my pageAdapter updates the correct page, but how do I achieve that?
For a better understanding why I want to achieve that, that I receive a json string within 3 node of type menu and I want to use each of them as a page in my viewPager.
Can someone show me a short and easy example for such a behavior? I think its a basic approach, so it cant be so difficult.
--------Edit---------
Here is the code:
public class FragmentPagerSupport extends FragmentActivity {

MyAdapter mAdapter;
ViewPager mPager;
#Override
public void onBackPressed() {
FragmentManager fm = getFragmentManager();
if (fm.getBackStackEntryCount() > 0) {
fm.popBackStack();
} else {
super.onBackPressed();
}
}
public MyAdapter getmAdapter() {
return mAdapter;
}
public ViewPager getmPager() {
return mPager;
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.fragment_pager);
mAdapter = new MyAdapter(getFragmentManager(), this);
mPager = (ViewPager) findViewById(R.id.pager);
mPager.setOffscreenPageLimit(NUM_ITEMS + 2);
mPager.setAdapter(mAdapter);
Button button = (Button) findViewById(R.id.goto_first);
button.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
mPager.setCurrentItem(0);
}
});
button = (Button) findViewById(R.id.goto_last);
button.setOnClickListener(new OnClickListener() {

Hi I was facing same kind of issue. I fixed the issue by using
getChildFragmentManager().beginTransaction()
instead of
getActivity().getSupportFragmentManager().beginTransaction()
As in this case we are trying to make transaction from within a fragment (one out of the list of fragments which are attached to the ViewPager, thus the Activity holding the ViewPager) so we have to use getChildFragmentManager() here for desired results.
NOTE: I am using android support v4 library and thus corresponding FragmentManager.
