I'm using 1 Activity and 4 TabFragment in Android. When I add a keylistener in second TabFragment using EditText , My first TabFragment opens keyboard. I controlled that 2 xml_layout different each other.
So any idea why Fragments affect each other and how to prevent this ? . Did you anyone face that problem ?

In order for the Adapter to know how many pages it has, you need to override getCount method. You did override it, but used 0 as the number of pages, thus having no pages.
In your FragmentAdapter class, try changing this:
#Override
public int getCount() {
return 0;
}
To this:
#Override
public int getCount() {
return tabcount;
}
I have implemented the SwipeRefreshLayout in many of the pages,and it working fine. but here i got stuck with one specific implementation , where i have a SwipeRefreshLayout for the ViewPager and ViewPager holding the FragmentPagerAdapter.
In my case , I have a ViewPager with two tabs and each holding the fragment with RecyclerView. On main page I have a SwipeRefreshLayout and on the onRefresh i need to load the API and update the fragments in ViewPager. Updating is working fine but unfortunately RecyclerView inside the Fragment ( ViewPager tab Item ) not scrolling top and it always calling the SwipeToRefresh.
I am familiar with using the SwipeRefreshLayout with RecyclerView, but here the problem is the main child of the SwipeRefreshLayout is ViewPager and it having the Fragment inside it and that fragment is holding the RecyclerView.
I have a thought of moving the SwipeRefreshLayout inside the fragments for the RecyclerView , but again here i have challenges like both the Fragments is having the same API. So that i am using the SwipeRefreshLayout directly on ViewPager to refresh my data.
Here is some of my codes.

similarly i have Favorites example as well. Mostly both will look like same, that's why not posting it here.
Sorry for posting the long question. Any help regarding this. Apologies for my poor English. Thanks in Advance.
I am currently doing this android tutorial https://www.androidhive.info/2016/05/android-build-intro-slider-app/ .
I want to implement the onClick() event inside the viewpager page like if I clicked the text, it will direct me to another page.
Is it possible? If possible, please help me? Thanks

In my android activity I have a radio button group and a tab layout using viewpager.
There are two tabs and 2 radio buttons.
The first tab is an attachment tab
second one is an event tab.
When i checked the first radio button then user is not allowed to see the first tab,so i need to disable the first tab and shows the second tab for the user.If i selected the second radio button i need to enable the first tab and user is allowed to access the first tab.I don't want to remove the tab,i just want to disable it so that user can't access it by swiping or clicking on the tab.
How to do that? Below is my code to show tab.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.create_asset);
//remaining code
viewPager2 = (ViewPager) findViewById(R.id.viewPager2);
setupViewPager2(viewPager2);
tabLayout2 = (TabLayout) findViewById(R.id.tab_layout2);
tabLayout2.setupWithViewPager(viewPager2);//setting tab over viewpager
rdbGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
}
});
#Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
//Implementing tab selected listener over tablayout
tabLayout2.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
#Override
public void onTabSelected(TabLayout.Tab tab) {
viewPager2.setCurrentItem(tab.getPosition());//setting current selected item over viewpager
switch (tab.getPosition()) {
case 0:
Log.e("TAG","TAB1");
break;
case 1:
Log.e("TAG","TAB2");
break;
}
}
#Override
public void onTabUnselected(TabLayout.Tab tab) {
}
#Override
public void onTabReselected(TabLayout.Tab tab) {
}
});
}
//Setting View Pager
private void setupViewPager2(ViewPager viewPager) {
expAttList = new ArrayList<COAAccount>();
adapter2 = new ViewPagerAdapter(getSupportFragmentManager());
adapter2.addFrag(new AttachmentFragment("Attachments",expAttList,fontFamily), "Attachments");
adapter2.addFrag(new EventFragment("Events",fontFamily), "Events");
viewPager2.setAdapter(adapter2);
}
//View Pager fragments setting adapter class
class ViewPagerAdapter extends FragmentPagerAdapter {
private final List<Fragment> mFragmentList = new ArrayList<>();//fragment arraylist
private final List<String> mFragmentTitleList = new ArrayList<>();//title arraylist
public ViewPagerAdapter(FragmentManager manager) {
super(manager);
}
#Override
public Fragment getItem(int position) {
return mFragmentList.get(position);
}
#Override
public int getCount() {
return mFragmentList.size();
}
//adding fragments and title method
public void addFrag(Fragment fragment, String title) {
mFragmentList.add(fragment);
mFragmentTitleList.add(title);
}
#Override
public CharSequence getPageTitle(int position) {
return mFragmentTitleList.get(position);

It's a tricky one.You need to use a custom ViewPager for this.Below is the code.
Change your ViewPager in xml to this :
<yourPackage.NonSwipeableViewPager
android:id="#+id/pager"
android:layout_width="match_parent"
android:layout_height="400dp"
android:layout_below="#id/tab_layout"/>
Below is the custom view pager class :
public class NonSwipeableViewPager extends ViewPager {
private boolean enabled;
public NonSwipeableViewPager(Context context) {
super(context);
this.enabled = true;
}
public NonSwipeableViewPager(Context context, AttributeSet attrs) {
super(context, attrs);
this.enabled = true;
}
#Override
public boolean onInterceptTouchEvent(MotionEvent event) {
if (this.enabled) {
return super.onInterceptTouchEvent(event);
}
return false;
}
#Override
public boolean onTouchEvent(MotionEvent event) {
if (this.enabled) {
return super.onTouchEvent(event);
}
return false;
}
public void setPagingEnabled(boolean enabled) {
this.enabled = enabled;
}
}
Now in your activity use below code :
NonSwipeableViewPager viewPager = (NonSwipeableViewPager) findViewById(R.id.pager);
//write code to set viewpager to the tablayout that u have already done.Use the same.
rdbGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
pos = rdbGroup.indexOfChild(findViewById(checkedId));
LinearLayout tabStrip = ((LinearLayout)tabLayout.getChildAt(0));
switch (pos) {
case 0:
viewPager.setCurrentItem(1);
viewPager.setPagingEnabled(false);
tabstrip.getChildAt(0).setClickable(false);
tabstrip.getChildAt(0).setEnabled(false);
break;
case 1:
viewPager.setCurrentItem(0);
viewPager.setPagingEnabled(true);
tabstrip.getChildAt(0).setClickable(true);
tabstrip.getChildAt(0).setEnabled(true);
break;
default:
//here add whatever you like
break;
}
}
});
Use the swicth condition as per your requirement.
You can try this:
ViewPager viewPager2;
TabLayout tabLayout2;
ViewPagerAdapter adapter2;
RadioGroup rdbGroup;
RadioButton rdb1, rdb2;
LinearLayout tabstrip;
int pos;
#Override
protected void onCreate(Bundle savedInstanceState) {

setContentView(R.layout.activity_main);
//remaining code
viewPager2 = (ViewPager) findViewById(R.id.viewPager2);
setupViewPager2(viewPager2);
tabLayout2 = (TabLayout) findViewById(R.id.tab_layout2);
rdbGroup = (RadioGroup) findViewById(R.id.rdbGroup);
rdb1 = (RadioButton) findViewById(R.id.rdb1);
rdb2 = (RadioButton) findViewById(R.id.rdb2);
tabLayout2.setupWithViewPager(viewPager2);//setting tab over viewpager
//get position of already checked radiobutton
int radioButtonID = rdbGroup.getCheckedRadioButtonId();
View radioButton = rdbGroup.findViewById(radioButtonID);
pos = rdbGroup.indexOfChild(radioButton);
tabstrip = (LinearLayout) tabLayout2.getChildAt(0);
//check which radiobutton is already checked and as per its pos disbale or enable the tabs as below
if (pos == 0) {
tabLayout2.getTabAt(1).select();
tabstrip.getChildAt(0).setClickable(false);
tabstrip.getChildAt(0).setEnabled(false);
} else if (pos == 1) {
tabstrip.getChildAt(0).setClickable(true);
tabstrip.getChildAt(0).setEnabled(true);
}
rdbGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
pos = rdbGroup.indexOfChild(findViewById(checkedId));
switch (pos) {
case 0:
tabstrip.getChildAt(0).setClickable(false);
tabstrip.getChildAt(0).setEnabled(false);
break;
case 1:
tabstrip.getChildAt(0).setClickable(true);
tabstrip.getChildAt(0).setEnabled(true);
break;
default:
//here add whatever you like
tabstrip.getChildAt(0).setClickable(true);
tabstrip.getChildAt(0).setEnabled(true);
break;
}
}
});
//Implementing tab selected listener over tablayout
tabLayout2.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
#Override
public void onTabSelected(TabLayout.Tab tab) {
viewPager2.setCurrentItem(tab.getPosition());//setting current selected item over viewpager
switch (tab.getPosition()) {
case 0:
Log.e("TAG", "TAB1");
break;
case 1:
Log.e("TAG", "TAB2");
break;
}
}
#Override
public void onTabUnselected(TabLayout.Tab tab) {
}
#Override
public void onTabReselected(TabLayout.Tab tab) {
}
});
}
//Setting View Pager
private void setupViewPager2(ViewPager viewPager) {
expAttList = new ArrayList<COAAccount>();
expAttList = new ArrayList<COAAccount>();
adapter2 = new ViewPagerAdapter(getSupportFragmentManager());
adapter2.addFrag(new AttachmentFragment("Attachments", expAttList, fontFamily), "Attachments");

viewPager2.setAdapter(adapter2);
}
//View Pager fragments setting adapter class

My application has a list of dummy items managed by a SQLiteDatabase which contain a title String, a description String, a Boolean like status, and a list of images (I plan to implement them as downloading from String urls but presently I'm just trying with a single image resource). I am having two problems in the Detail View.
My intention is to use a ViewPager with a FragmentStatePagerAdapter to show the detail view, which consists of a ViewPager with a custom PagerAdapter for showing the list of images, TextView for title and description, a ToggleButton for the like status and a delete button for deleting items from the list.
Issues:
The ViewPager with the custom PagerAdapter does not display the image. It occupies the expected space and swipes performed on it also behave as expected. Only the image is not visible.
[RESOLVED] On using the delete button, I am able to delete the item from the database, and also update the Master View accordingly, but I am not able to update the Detail View, and the app crashes.
Here is my code:
Code that calls ItemDetailActivity.java
#Override
public void onClick(View v) {
Intent detailIntent = new Intent(getContext(), ItemDetailActivity.class);
detailIntent.putExtra(ItemDetailFragment.ARG_LIST_POSITION, holder.position);
getContext().startActivity(detailIntent);
}
ItemDetailActivity.java
public class ItemDetailActivity extends FragmentActivity {
static ItemDetailPagerAdapter idpa;
static ViewPager detailPager;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_item_detail);
idpa = new ItemDetailPagerAdapter(getSupportFragmentManager());
// Show the Up button in the action bar.
getActionBar().setDisplayHomeAsUpEnabled(true);
detailPager = (ViewPager) findViewById(R.id.item_detail_container);
detailPager.setAdapter(idpa);
detailPager.setCurrentItem(getIntent().getIntExtra(ItemDetailFragment.ARG_LIST_POSITION, 0));
}
}

int c = database.getCount();
closeDatabase();
return c;
}
#Override
public int getItemPosition(Object object) {
long mId = ((ItemDetailFragment) object).getmId();
int pos = POSITION_NONE;
openDatabase();
if (database.contains(mId)) {
pos = database.getPositionById(mId);
}
closeDatabase();
return pos;
}
}
Any help is much appreciated. Thanks :)
In your ItemDetailFragment, remove the viewpager from the holder, it should be directly into the returned view, something like this:
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_item_detail,
container, false);
pager = (ViewPager) rootView.findViewById(R.id.pager);
ImagePagerAdapter adapter = new ImagePagerAdapter(mItem, getActivity(),inflater, position);
pager.setAdapter(adapter);
return rootView;
}
and the ViewHolder pattern should be applied inside your PagerAdapter.
In ImagePagerAdapter.java, correct the isViewFromObject method -
#Override
public boolean isViewFromObject(View view, Object object) {
return (view == (View) object);
}
This will correct the issue of the ImageView.
In ItemDetailPagerAdapter.java, override the getItemPosition method -
#Override
public int getItemPosition(Object object) {
int ret = POSITION_NONE;
long id = ((ItemDetailFragment) object).getId();
openDatabase();
if (databaseContains(id)) {
ret = positionInDatabase(id);
}
closeDatabase();
return ret;
}
On deleting call the FragmentStatePagerAdapter.NotifyDataSetChanged() method. This will make the Adapter update itself on deleting.
Although, the FragmentStatePagerAdapter uses a list of Fragments and of stored states to implement the adapter. That is also causing trouble. To remove that, implement your own list of Fragments.
