New Activity intent onClick in viewPager Slides - android

Below is my Code.
Using ViewPager I have made 2 XML file for two Pages and their Class file.
Now I need if I click on First Screen of ViewPager, a new activity should launch.
I got 2 pages, so If I Click First Screen, A.class intent Called. If I click on Second Screen, B.class intent should be Called.
Codes:-
MainActvity:
public class MainActivity extends ActionBarActivity {
ViewPager mViewPager;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mViewPager = (ViewPager) findViewById(R.id.pager);
/** set the adapter for ViewPager */
mViewPager.setAdapter(new SamplePagerAdapter(
getSupportFragmentManager()));
}
/** Defining a FragmentPagerAdapter class for controlling the fragments to
be shown when user swipes on the screen. */
public class SamplePagerAdapter extends FragmentPagerAdapter {
public SamplePagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int position) {
/** Show a Fragment based on the position of the current screen */
if (position == 0) {
return new SampleFragment();
} else
return new SampleFragmentTwo();
}
#Override
public int getCount() {
// Show 2 total pages.
return 2;
}
}
}
SampleFragment.java
public class SampleFragment extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_one, null);
return rootView;
}
}
SampleFragmentTwo.java
public class SampleFragmentTwo extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_two, container,
false);
return rootView;
}
}
CustomSwipeAdapter:
public class CustomSwipeAdapter extends PagerAdapter {
#Override
public int getCount() {
return 0;
}
#Override
public boolean isViewFromObject(View view, Object object) {
return false;
}
#Override
public Object instantiateItem(ViewGroup container, int position) {
return super.instantiateItem(container, position);
}
#Override
public void destroyItem(ViewGroup container, int position, Object object) {
super.destroyItem(container, position, object);
}
}

As mentioned in one of the comments, In your fragment classes A and B put onClick listener on views and launch intent from there like below:
public class SampleFragment extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_one, null);
rootView.setOnClickListener(new View.OnClickListener(){
public void onClick(View v) {
// do something when the button is clicked
Intent activityA = new Intent(getActivity(),ActivityA.class);
startActivity(activityA);
}
return rootView;
}
}
similarlly goes for your second fragment.

Refresh current fragment in tabbed layout viewpager

I am trying to refresh the current fragment in the tabbed layout of my viewpager. I have one fragment (UserProgressFragment) that creates the ViewPager and sets the adapter (UserProgressAdapter) along with creating tabbed layout.
In my UserProgressAdapter, in the getItem() method I am returning two other fragments, (UserWeightTrackerFragment and UserCalorieCounterFragment) based on which tab i am on.
My issue is how do i refresh the fragment and update its content/view from the UserCalorieCounterFragment on a button click, because access to the viewpager and adapter are set in the UserProgressFragment? I have considered notifyDataChange for the adapter but i dont know how to call this from this class as it is set up on the UserProgressFragment class. The purpose of wanting to refresh this page is to update a specific view which is a chart, if context is needed.
I have attached the code below:
UserProgressFragment
public class UserProgressFragment extends Fragment{
public static UserProgressFragment newInstance() {
return new UserProgressFragment();
}
public UserProgressFragment() {
// Required empty public constructor
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.fragment_user_progress, container, false);
ViewPager viewPager = view.findViewById(R.id.progress_viewpager);
viewPager.setAdapter(new UserProgressTabsAdapter(getChildFragmentManager()));
TabLayout tabLayout = view.findViewById(R.id.progress_sliding_tabs);
tabLayout.setupWithViewPager(viewPager, true);
return view;
}
}
UserProgressTabsAdapter
public class UserProgressTabsAdapter extends FragmentStatePagerAdapter {
private static final int PAGE_COUNT = 2;
private String tabTitles[] = new String[]{"Weight Tracker", "Calorie Counter"};
public UserProgressTabsAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int position) {
switch (position) {
case 0:
return UserWeightTrackerFragment.newInstance(position);
case 1:
return UserCalorieCounterFragment.newInstance(position + 1);
}
return null;
}
#Override
public int getCount() {
return PAGE_COUNT;
}
#Override
public CharSequence getPageTitle(int position) {
// Generate title based on item position
return tabTitles[position];
}
UserCalorieCounterFragment (need to refresh this one)
public class UserCalorieCounterFragment extends Fragment implements View.OnClickListener, AdapterView.OnItemSelectedListener {
public static final String ARG_PAGE = "ARG_PAGE";
public static UserCalorieCounterFragment newInstance(int page) {
Bundle args = new Bundle();
args.putInt(ARG_PAGE, page);
UserCalorieCounterFragment fragment = new UserCalorieCounterFragment();
fragment.setArguments(args);
return fragment;
}
public UserCalorieCounterFragment() {
// Required empty public constructor
}
#Override
public void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
int mPage = getArguments().getInt(ARG_PAGE);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.fragment_user_calorie_counter, container, false);
Button mAddCalories = view.findViewById(R.id.btn_add_calorie);
mAddCalories.setOnClickListener(this);
return view;
}
#Override
public void onClick(View view) {
switch (view.getId()) {
case R.id.btn_add_calorie:
//REFRESH/UPDATE HERE
break;
}
}
You can create a public method in your fragment which contains the view pager which will contain the notifyDataSetChanged() function. And in the view pager fragment/item, you can call getParentFragment() and type cast it to your parent/first fragment and access that public method to notifyDataSetChanged().

How to add function in fragment

EDIT:
I'm new in android and i try to use fragments in my app. I try to use a fragment function in my activity but i got a null pointer exception..
Fragment:
public class VideoviewFragment extends Fragment {
private View card;
public static VideoviewFragment create() {
return new VideoviewFragment();
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_videoview, container, false);
card = (View) view.findViewById(R.id.card_video);
return view;
}
public void setalphacard(float value){
card.setAlpha(value);
}
}
In main activity i want to do that for example (i simplified my code):
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Viewpager
final SmartFragmentStatePagerAdapter adapterViewPager;
final ViewPager viewPager = (ViewPager) findViewById(R.id.am_view_pager);
adapterViewPager = new MainPagerAdapter(getSupportFragmentManager());
viewPager.setAdapter(adapterViewPager);
final VideoviewFragment videoviewFragment = (VideoviewFragment) adapterViewPager.getRegisteredFragment(2);
videoviewFragment.setalphacard(0.3f);
}
}
Main pager adapter:
public class MainPagerAdapter extends SmartFragmentStatePagerAdapter {
public MainPagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int position) {
switch (position){
case 0:
return CameraFragment.create();
case 1:
return OptionFragment.create();
case 2:
return VideoviewFragment.create();
}
return null;
}
#Override
public int getCount() {
return 3;
}
}
You just have to declare the View globally like this:
public class VideoviewFragment extends Fragment {
private View card;
public static VideoviewFragment create() {
return new VideoviewFragment();
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_videoview, container, false);
card = (View) view.findViewById(R.id.card_video);
return view;
}
public void setalphacard(float value){
card.setAlpha(value);
}
}
Declare your View Object globally in your fragment.

Log Error in Nested Fragments on View Pager : No view found for id

I have a fragment that Contains view pager.there are three fragments in that Main fragment they are Fragment A,Fragment B,Fragment C. Upto this code runs properly.
Then i added a new Fragment and called via Fragment A then i got the error in the Log

How do I detect a button pressed in an Android ViewPager?

I created a ViewPager that uses individual Fragments. There are 3, here is an example of one of them:
public class PainFragment extends Fragment {
private TextView mTxtScale;
private Button mBtnMinus;
private Button mBtnPlus;
private int mScale;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_pain, container, false);
mTxtScale = (TextView)v.findViewById(R.id.scale);
mBtnMinus = (Button)v.findViewById(R.id.minus);
mBtnPlus = (Button)v.findViewById(R.id.plus);
mScale = Integer.valueOf(mTxtScale.getText().toString());
mBtnMinus.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
mScale--;
if(mScale == -1) {
mScale = 9;
}
mTxtScale.setText(String.valueOf(mScale));
}
});
mBtnPlus.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
mScale++;
if(mScale == 10) {
mScale = 0;
}
mTxtScale.setText(String.valueOf(mScale));
}
});
return v;
}
public static PainFragment newInstance(String text) {
PainFragment f = new PainFragment();
Bundle b = new Bundle();
//b.putString("msg", text);
f.setArguments(b);
return f;
}
public int getScale() {
int scale = Integer.valueOf(mTxtScale.getText().toString());
return scale;
}
And I instantiated the ViewPager in my MainFragment:
public class MainFragment extends Fragment {
Entry mEntry = new Entry();
ViewPager mPager;
JournalPagerAdapter mAdapter;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_main_screen, container, false);
mPager = (ViewPager)rootView.findViewById(R.id.pager);
mPager.setOffscreenPageLimit(2); // So all 3 pages are loaded at once.
mAdapter = new JournalPagerAdapter(getActivity().getSupportFragmentManager());
mPager.setAdapter(mAdapter);
...
I have button click listeners in the ViewPager Fragments. I would like to know the best way to set up a listener so that my main fragment can detect when a button is pressed on one of the ViewPager fragments.
/** Update - Here is my adapter class **/
public class JournalPagerAdapter extends FragmentPagerAdapter {
SparseArray<Fragment> registeredFragments = new SparseArray<Fragment>();
public JournalPagerAdapter(FragmentManager mgr) {
super(mgr);
}
#Override
public Fragment getItem(int pos) {
switch(pos) {
case 0: return PainFragment.newInstance("PainFragment");
case 1: return StressFragment.newInstance("StressFragment");
case 2: return SleepFragment.newInstance("SleepFragment");
default: return PainFragment.newInstance("PainFragment");
}
}
#Override
public int getCount() {
return 3;
}
/* Thanks to Streets of Boston (http://stackoverflow.com/questions/8785221/retrieve-a-fragment-from-a-viewpager)
* for the next 3 methods, should include in all PagerAdapters. Let's you get the fragment instances by position */
#Override
public Object instantiateItem(ViewGroup container, int position) {
Fragment fragment = (Fragment) super.instantiateItem(container, position);
registeredFragments.put(position, fragment);
return fragment;
}
#Override
public void destroyItem(ViewGroup container, int position, Object object) {
registeredFragments.remove(position);
super.destroyItem(container, position, object);
}
public Fragment getRegisteredFragment(int position) {
return registeredFragments.get(position);
}
}
Second answer with pseudo example of using a ClickListener instead of the Callback. This should let you keep all logic out of the Activity.
Implement OnClickListener interface in MainFragment. Add a OnClickListener to your JournalPagerAdapter constructor. Presumably the Adapter is creating the PainFragments. Add OnClickListener to PainFragment newInstance and have the Adapter provide it when it creates each PainFragment.
public class PainFragment extends Fragment {
private TextView mTxtScale;
private Button mBtnMinus;
private Button mBtnPlus;
private int mScale;
protected OnClickListener mainClickListener;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_pain, container, false);
mTxtScale = (TextView)v.findViewById(R.id.scale);
mBtnMinus = (Button)v.findViewById(R.id.minus);
mBtnPlus = (Button)v.findViewById(R.id.plus);
mScale = Integer.valueOf(mTxtScale.getText().toString());
mBtnMinus.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
mScale--;
if(mScale == -1) {
mScale = 9;
}
mTxtScale.setText(String.valueOf(mScale));
mainClickListener.onClick(view);
}
});
mBtnPlus.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
mScale++;
if(mScale == 10) {
mScale = 0;
}
mTxtScale.setText(String.valueOf(mScale));
mainClickListener.onClick(view);
}
});
return v;
}
public static PainFragment newInstance(String text, OnClickListener onClickListener) {
PainFragment f = new PainFragment();
f.mainClickListener = onClickListener;
Bundle b = new Bundle();
//b.putString("msg", text);
f.setArguments(b);
return f;
}
public int getScale() {
public class MainFragment extends Fragment implements OnClickListener {
Entry mEntry = new Entry();
ViewPager mPager;
JournalPagerAdapter mAdapter;
#Override
public void onClick(View v)
{
// TODO Auto-generated method stub
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_main_screen, container, false);
mPager = (ViewPager)rootView.findViewById(R.id.pager);
mPager.setOffscreenPageLimit(2); // So all 3 pages are loaded at once.
mAdapter = new JournalPagerAdapter(getActivity().getSupportFragmentManager(), this);
mPager.setAdapter(mAdapter);
...
public class JournalPagerAdapter extends FragmentPagerAdapter {
SparseArray<Fragment> registeredFragments = new SparseArray<Fragment>();
private OnClickListener mOnClickListener;
public JournalPagerAdapter(FragmentManager mgr, OnClickListener onClickListener) {
super(mgr);
mOnClickListener = onClickListener;
}
#Override
public Fragment getItem(int pos) {
switch(pos) {
case 0: return PainFragment.newInstance("PainFragment", mOnClickListener);
case 1: return StressFragment.newInstance("StressFragment", mOnClickListener);
case 2: return SleepFragment.newInstance("SleepFragment", mOnClickListener);
default: return PainFragment.newInstance("PainFragment", mOnClickListener);
}
}
...
The proper way to achieve this is probably through the use of a callback. Your fragment would utilize a normal click listener which would then use a callback to communicate back to the hosting Activity.
See the Android docs regarding communicating from a Fragment back to the Activity; then the Activity can communicate it to other Fragments.
http://developer.android.com/guide/components/fragments.html#CommunicatingWithActivity
In some cases, you might need a fragment to share events with the activity. A good way to do that is to define a callback interface inside the fragment and require that the host activity implement it. When the activity receives a callback through the interface, it can share the information with other fragments in the layout as necessary.

how to access the value of edittext inside fragment which is in a viewpager

I am having am mainActivity which consists of 3 fragment activity in a view pager .each fragment consists of edit texts .How to get the value of the edit text when swipe fragment horizontally ? I am trying to do like this.below code
public class MainActivity extends FragmentActivity {
int value = 0;
Context context;
String a = "";
SectionsPagerAdapter mSectionsPagerAdapter;
ViewPager mViewPager;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

return view;
}
}
public class PageOne extends Fragment {

}
#Override

when i try to access the eddittext inside pageZero class like below
name=(EditText)view.findViewById(R.id.nameTV);
a=name.getText().toString().trim();
i am getting null value.help me out..Thanks in advance.
Change the pagezero class oncreateview code like this .....
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view =getActivity().getLayoutInflater().inflate(R.layout.componentname,null);
name=(EditText)view.findViewById(R.id.nameTV);
name.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
a=name.getText().toString().trim();
Toast.makeText(getApplicationContext(),a,Toast.LENGTH_SHORT).show();
}
return view;
});
Return the view friend and then use default layout inflater...
At the time you click the edittext field, is there any content? Maybe you should get the text in the lost focus event of the edittext field. Thus you can enter some text first...
Example:
name.setOnFocusChangeListener(new OnFocusChangeListener() {
#Override
public void onFocusChange(View v, boolean hasFocus) {
if(hasFocus == false){
//get text from edittext field...
}
}
});
The way you try to get the text looks right to me. At least I do it the same way.
In the PagerAdapter's 'getItem' Method you should instantiate your fragments directly:
#Override
public Fragment getItem(int position) {
switch (position) {
case 0:
return new PageZero();
case 1:
return new PageOne();
case 2:
return new PageTwo();
}
return null;
}
The Viewpager only calls getItem if it wants to create a new item. Unfortunatly they called the method getItem and not createItem which would be more obvious.
Get your EditText inside onClick block...
This mean change the code from:
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.componentname, container, false);
name=(EditText)view.findViewById(R.id.nameTV);
name.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
a=name.getText().toString().trim();
Toast.makeText(getApplicationContext(),a,Toast.LENGTH_SHORT).show();
}
});
return view;
}
To:
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.componentname, container, false);
name.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// GET EDIT TEXT HEAR:
EditText name=(EditText)view.findViewById(R.id.nameTV);
a=name.getText().toString().trim();
Toast.makeText(getApplicationContext(),a,Toast.LENGTH_SHORT).show();
}
});
return view;
}
To create a 3 different fragments with view pager you should:
1)Create FragmentActivity with view pager and view pager adapter.
public class FragmentActivity extends FragmentActivity
{
private FragmentAdapter adapter;
private ViewPager pager;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_fragment);
adapter = new FragmentAdapter(getSupportFragmentManager());
pager = (ViewPager) findViewById(R.id.pager);
pager.setAdapter(adapter);
}
2)Create 3 Fragments with static instance
public final class Fragment1 extends Fragment
{
public static Fragment1 newInstance() {
return new Fragment1();
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
LinearLayout layout = new LinearLayout(getActivity());
// your fragment xml view
return view;
}
}
3)Fill view pager adapter with it;
public class FragmentAdapter extends FragmentPagerAdapter
{
public InstallFragmentAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int position) {
switch (position) {
case 0:
return Fragment1.newInstance();
case 1:
return Fragment2.newInstance();
case 2:
return Fragment3.newInstance();
}
return null;
}
}
public class PageZero extends Fragment {
public static EditText name; //change this to public static
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.componentname, container,
false);
name = (EditText)view.findViewById(R.id.nameTV);
name.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
}
});
return view;
}
}
Then, you can access the public static EditText name (after the view for it has been generated of course) from another fragment like this.
public class PageOne extends Fragment {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.componentaddress, container,
false);
EditText page_one_text = PageZero.name; //you can get that variable in any fragment now, but using the class name of that fragment to access it
return view;
}
}
Cheers. Please mark this as the correct answer if it helps you. You have quite a bit of answers here
I tried below code. Working for me
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_main_explore, container, false);
ed1 = (EditText)v.findViewById(R.id.editTextTemp);
if( ed1 == null )
{
Toast.makeText(getActivity(), "ERROR UNABLE TO GET EDIT", Toast.LENGTH_LONG).show();
}
// Inflate the layout for this fragment
//return inflater.inflate(R.layout.fragment_main_explore, container, false);
return v;
}
