Introduction Screen Button ViewPager

I'm facing an issue regarding intro screen in android.
I create button in one fragment but i'm trying to call this button in welcomeActivity through layoutinflate in activity but it doesn't perform any functionality.
XML Fragment(custom_intro):
<?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"
>
<Button
android:id ="#+id/explore"
android:layout_width="200dp"
android:layout_height="wrap_content"
android:text="Explore"
android:background="#drawable/round_button"
android:padding="15dp"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:layout_marginBottom="114dp" />
</RelativeLayout>
WelcomeActivityLayout
<?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"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/colorPrimaryDark">
<!--tools:showIn="#layout/welcome_activity"-->
<android.support.v4.view.ViewPager
android:id="#+id/view_pager"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentTop="true"
android:layout_alignParentStart="true" />
</RelativeLayout>
WelcomeActivityJava:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.welcome_activity);
LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
customView = inflater.inflate(R.layout.custom_intro, null);
Button button=(Button)customView.findViewById(R.id.explore);
button.setText("Test");
Int[] layouts = new int[]{
R.layout.custom_intro,
R.layout.custom_intro1,
R.layout.custom_intro2,
R.layout.custom_intro3,
R.layout.custom_intro4};
myViewPagerAdapter = new MyViewPagerAdapter();
viewPager.setAdapter(myViewPagerAdapter);
viewPager.addOnPageChangeListener(viewPagerPageChangeListener);
viewPagerIndicator.setupWithViewPager(viewPager);
viewPagerIndicator.addOnPageChangeListener(viewPagerPageChangeListener);
}

If you want to access the Button of Fragment inside its parent Activity then you should define a method inside your Fragment class like this:
public class MyFragment extends Fragment {
TextView mTextView;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.activity_main, container, false);
mButton = (Button) view.findViewById(R.id.textView1);
return view;
}
public void setButtonText(String value){
mTextView.setText(value);
}
}
Then you can use this inside your Activity like this:
myFragment.setButtonText("Test");

How to save scroll position of recyclerview in fragment

I have followed so many answers from here.. but not a single one solving my issue .. that's why i am asking.
I want to save scroll position in a fragment.
In So many articles they have suggested to follow
#Override
protected void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
}
and
#Override
protected void onRestoreInstanceState(Bundle savedInstanceState) {
super.onRestoreInstanceState(savedInstanceState);
}
But this two method is not available in fragment.
My code:
private int mPositionIng = RecyclerView.NO_POSITION;
private String KEY_POSITION_ING = "KeyPositionIng";
in OnCreateView()
if (savedInstanceState != null) {
if (savedInstanceState.containsKey(KEY_POSITION_ING)) {
mPositionIng = savedInstanceState.getInt(KEY_POSITION_ING);
}
}
Override Methods in fragment They are not same method as above. i don't know where i am doing wrong.
#Override
public void onSaveInstanceState(Bundle outState) {
int scrollPositionIng = mRecyclerViewIngredients.computeVerticalScrollOffset();
mPositionIng = scrollPositionIng;
outState.putInt(KEY_POSITION_ING, mPositionIng);
super.onSaveInstanceState(outState);
}
#Override
public void onViewStateRestored(#Nullable Bundle savedInstanceState) {
if (mPositionIng != RecyclerView.NO_POSITION) {
mRecyclerViewIngredients.getLayoutManager().scrollToPosition(mPositionIng);
}
super.onViewStateRestored(savedInstanceState);
}
I just need to save scroll position while the orientation changes .. Please help.
Any Suggestion will be help full. Thanks......

Update
Everything I wrote below is correct, but the reason it didn't work for you is that I didn't realize how your Activity's layout was structured. Here is your Activity's layout (slightly cleaned up):
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
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"
tools:context="com.tapan.recipemaster.activity.RecipeDetailActivity">
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<FrameLayout
android:id="#+id/fl_fragment_detail"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="#dimen/padding_10dp"/>
</RelativeLayout>
</ScrollView>
</android.support.constraint.ConstraintLayout>
Meanwhile, this is your Fragment's layout (again, slightly cleaned up):
<FrameLayout
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"
tools:context="com.tapan.recipemaster.fragment.RecipeDetailFragment">
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">

android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="#dimen/padding_10dp"
android:orientation="vertical">
<LinearLayout

android:layout_height="match_parent"
android:background="#color/colorAccent"
android:orientation="vertical">

<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">

android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="#dimen/dimen_8dp"
android:textColor="#color/colorPrimaryDark"

android:text="Steps"/>
<android.support.v7.widget.RecyclerView

android:layout_marginTop="#dimen/dimen_8dp"/>
</LinearLayout>
</LinearLayout>
</ScrollView>
</FrameLayout>
Both RecyclerViews have android:layout_height="wrap_content", which means they do not scroll. Rather, the ScrollView in your Activity is the view providing the scrolling behavior, so it is this view whose scroll position must be saved.
You can have the system do this for you by giving this ScrollView an id. Any id you want, as long as it's unique. You don't have to write any Java at all.
<ScrollView
android:id="#+id/thisfixestheproblem"
android:layout_width="match_parent"
android:layout_height="match_parent">
Make sure you're modifying the ScrollView in your activity's layout, not the one in your fragment's layout.
Original
None of the code you posted should be necessary to save your RecyclerView's scroll position on orientation change. As long as the RecyclerView has a unique ID in your layout, it will save the scroll position for you automatically.
Here is a very small sample app that shows automatic saving of scroll position, even with a dynamically added Fragment. As you can see, the only instance state I'm saving myself is whether the button to start the fragment should be visible.
MainActivity.java
public class MainActivity extends AppCompatActivity {
private Button button;
#Override
protected void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
outState.putBoolean("buttonVisible", button.getVisibility() == View.VISIBLE);
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
button = (Button) findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
getSupportFragmentManager()
.beginTransaction()
.replace(R.id.content, new MyFragment())
.commit();
button.setVisibility(View.GONE);
}
});
if (savedInstanceState != null) {
boolean buttonVisible = savedInstanceState.getBoolean("buttonVisible");
button.setVisibility(buttonVisible ? View.VISIBLE : View.GONE);
}
}
}
MyFragment.java
public class MyFragment extends Fragment {
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
View root = inflater.inflate(R.layout.myfragment, container, false);
RecyclerView recycler = (RecyclerView) root.findViewById(R.id.recycler);
recycler.setAdapter(new MyAdapter());
return root;
}
private static class MyAdapter extends RecyclerView.Adapter<MyViewHolder> {
#Override
public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
LayoutInflater inflater = LayoutInflater.from(parent.getContext());
View itemView = inflater.inflate(R.layout.itemview, parent, false);
return new MyViewHolder(itemView);
}
#Override
public void onBindViewHolder(MyViewHolder holder, int position) {
Drawable d = new ColorDrawable(Color.argb(0xff, 0, 0, position));
ViewCompat.setBackground(holder.image, d);
holder.text.setText("" + position);
}
#Override
public int getItemCount() {
return 256;
}
}
private static class MyViewHolder extends RecyclerView.ViewHolder {
final View image;
final TextView text;
MyViewHolder(View itemView) {
super(itemView);
this.image = itemView.findViewById(R.id.image);
this.text = (TextView) itemView.findViewById(R.id.text);
}
}
}

Let the Android OS handle that for you, in AndroidManifest.xml inside your wanted tag activity add:
android:configChanges="orientation|screenSize"

for future coders
I guess when you came back to your fragment you lost position this is because the values stored in the recycler view of the fragment is lost. If you keep code in start or other methods in fragment their scope is lost.
keep your code in On Create View in fragment because scope will not be lost it will work maximum times if not try by declaring all variables in class not in local method and initialize in oncreateview method. how to get context in on create view?? you can google

Fragment onCreateView is never called

I noticed that onCreateView() of one of my fragments is never called and i dont know why.I need to be able to make changes in onResume() but thats is also never called.
Here is how I add the fragments.
public class LiveGameStats extends FragmentActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_live_game_stats);
if (savedInstanceState == null) {
getSupportFragmentManager().beginTransaction().add(R.id.tab1, new Tab1Fragment()).commit();
}
FragmentTabHost mTabHost = (FragmentTabHost) findViewById(R.id.liveGameTabhost);
mTabHost.setup(LiveGameStats.this, getSupportFragmentManager(), R.id.liverealtabcontent);
mTabHost.addTab(mTabHost.newTabSpec("tab1").setIndicator("You"),
LiveGameTab1Fragment.class, null);
mTabHost.addTab(mTabHost.newTabSpec("tab2").setIndicator("Your Team"),
LiveGameTab2Fragment.class, null);
mTabHost.addTab(mTabHost.newTabSpec("tab3").setIndicator("Your Enemies"),
LiveGameTab3Fragment.class, null);
}
Tab1Fragment
public class Tab1Fragment extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View V = inflater.inflate(R.layout.tab1, container, false);
Log.v("FRAGMENT","FragmentActivityCreateView");
return V;
}
And finnaly the xml passed under R.layout.tab1
<?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"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".DeviceFragment" >
<ImageButton
android:id="#+id/searchBtn"
android:src="#drawable/waves"
android:background="#drawable/search_selector"
android:padding="40dp"
android:layout_height="200dp"
android:layout_width="200dp"
android:onClick="liveMatch"
android:layout_centerVertical="true"
android:layout_centerHorizontal="true" />
</RelativeLayout>
I think I might have created the fragments the wrong way. As you see it now they are created as the xml says but when I changed tabs, the content is "reseted".Any changed I placed in onCreateView() or onResume() is not called.
EDIT
I have tried to implement the method described in the 1st comment. After the implementation the tabs have the same content. Is like all the tabs have the same content. This time I posted all my classes and their associated XML.
public class LiveGameStats extends FragmentActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_live_game_stats);
if (savedInstanceState == null) {
getSupportFragmentManager().beginTransaction().add(R.id.liverealtabcontent, new LiveGameTab1Fragment()).commit();
getSupportFragmentManager().beginTransaction().add(R.id.liverealtabcontent, new LiveGameTab2Fragment()).commit();
getSupportFragmentManager().beginTransaction().add(R.id.liverealtabcontent, new LiveGameTab3Fragment()).commit();
}
FragmentTabHost mTabHost = (FragmentTabHost) findViewById(R.id.liveGameTabhost);
mTabHost.setup(LiveGameStats.this, getSupportFragmentManager(), R.id.liverealtabcontent);
mTabHost.addTab(mTabHost.newTabSpec("tab1").setIndicator("You"),
LiveGameTab1Fragment.class, null);
mTabHost.addTab(mTabHost.newTabSpec("tab2").setIndicator("Your Team"),
LiveGameTab2Fragment.class, null);
mTabHost.addTab(mTabHost.newTabSpec("tab3").setIndicator("Your Enemies"),
LiveGameTab3Fragment.class, null);
}
activity_live_game_stats.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:id="#+id/activity_live_game_stats"

android:layout_height="match_parent"
android:background="#android:color/holo_blue_light"

android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1" />
</LinearLayout>
</android.support.v4.app.FragmentTabHost>
</LinearLayout>
I wont post the code from LiveGameTab2 and LiveGameTab3 since they are almost the same. I have also another activity that
Edit2
Seems its solved when i changed from getSupportFragmentManager().beginTransaction().add(R.id.liverealtabcontent, new LiveGameTab1Fragment()).commit(); to getSupportFragmentManager().beginTransaction().add(android.R.id.tabcontent, new LiveGameTab1Fragment()).commit();

The problem is this:
getSupportFragmentManager().beginTransaction().add(R.id.tab1, new Tab1Fragment()).commit();
In the first argument you have to pass a id to a container in the Activity layout where your fragment will be attached.
You are passing a entire layout R.id.tab1.
Add a container view in activity_live_game_stats xml file,
<?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"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".DeviceFragment" >
<FrameLayout
android:id="#+id/myContainer"
...(Other attrs)>
</FrameLayout>
</RelativeLayout>
and then
if (savedInstanceState == null) {
getSupportFragmentManager().beginTransaction().add(R.id.myContainer, new Tab1Fragment()).commit();
}

Simple fragement is not working

I am practicing to multi-pane screen using fragment, but it's not working properly. I want two frame in single activity. One should be static and another will dynamic list.
main_biddingwindow.xml
<?xml version="1.0" encoding="utf-8"?>
<GridLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent"
android:minWidth="200dp"
android:weightSum="1"
android:id="#+id/ag">
<fragment
android:layout_width="163dp"
android:layout_height="match_parent"
android:name="driver.project_detail"
android:id="#+id/fragment"
android:layout_row="0"
android:layout_column="0" />
<fragment

main.class
public class biddingWindow extends Activity{
protected void OnCreate(Bundle b){
super.onCreate(b);
setContentView(R.layout.main_biddingwindow);
}
}
bidlist.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

</LinearLayout>
bid_list.java
public class bid_list extends Fragment {
public View onCreateView(LayoutInflater inflater ,ViewGroup container ,Bundle s){
return inflater.inflate(R.layout.bidlist,container, false);
}
}
output screen

Just Create the objects of both the fragments in activity and you can access everything in fragment
public class bid_list extends Fragment {
public ListView listView;
public View onCreateView(LayoutInflater inflater ,ViewGroup container ,Bundle s){
View view = inflater.inflate(R.layout.bidlist,container, false);
listView = (ListView)view.findViewById(R.id.listView);
return view ;
}
}

public class bid_list extends Fragment {
public ListView listView;
public View onCreateView(LayoutInflater inflater ,ViewGroup container ,Bundle s){
View view = inflater.inflate(R.layout.bidlist,container, false);
listView = (ListView)view.findViewById(R.id.listView);
return view ;
}
}

super.onCreate(b);
setContentView(R.layout.main_biddingwindow);
FrameLayout frame1 = (FrameLayout)findViewById(R.id.fragment);
FrameLayout frame2 = (FrameLayout)findViewById(R.id.fragment);
Fragment1 fragment1 = new Fragment1();
Fragment2 fragment2 = new Fragment2();
frame1.removeAllView();
frame1.addView(fragment1)
frame2.removeAllView();
frame2.addView(fragment2)
}
}

How to split window with a Viewpager and Fragment?

I want to make something like this:
As you can see, the ViewPager is at top and window is spitted in a Viewpager and a Fragment.
I have tried following:
activity_homescreen.xml:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".HomeScreenActivity" tools:ignore="MergeRootFrame"
>
<android.support.v4.view.ViewPager
android:id="#+id/home_screen_view_pager"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"/>
<fragment
android:id="#+id/homescreen_fragment"
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="wrap_content"
class="com.krupalandharsh.touristguideexperiments.HomeScreenFragment" />
</RelativeLayout>
fragment_homescreen.xml:
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center"
android:orientation="horizontal">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="login"/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="signup"/>
</LinearLayout>
HomeScreenActivity.java:
public class HomeScreenActivity extends Activity{
ViewPager homescreen_viewpager;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home_screen);
homescreen_viewpager = (ViewPager) findViewById(R.id.home_screen_view_pager);
HomeScreenImageAdapter adapter = new HomeScreenImageAdapter(this);
homescreen_viewpager.setAdapter(adapter);
}
}
HomeScreenFragment.java:
public class HomeScreenFragment extends Fragment{
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_homescreen, container, false);
return rootView;
}
}
HomeScreenImageAdapter.java
public class HomeScreenImageAdapter extends PagerAdapter {
private Context context;
private int[] HomeScreenImages = new int[] {
android.R.drawable.ic_menu_report_image,
android.R.drawable.ic_btn_speak_now,
android.R.drawable.ic_dialog_dialer,
};
public HomeScreenImageAdapter(Context context)
{
this.context = context;
}
#Override
public int getCount() {
return HomeScreenImages.length;
}
#Override
public boolean isViewFromObject(View view, Object object) {
return (view == ((ImageView)object));
}
#Override
public Object instantiateItem (ViewGroup container, int position){
ImageView imageview = new ImageView(context);
imageview.setImageResource(HomeScreenImages[position]);
imageview.setScaleType(ImageView.ScaleType.FIT_CENTER);
((ViewPager)container).addView(imageview);
return imageview;
}
#Override
public void destroyItem(ViewGroup container, int position, Object object) {
((ViewPager) container).removeView((ImageView) object);
}
}
But, I can't see m below fragment. Only ViewPager is showing. Is there any idea you have by which we can split screen in Viewpager and Fragment as above?

There may be other issues as well, but to start with, why not just use LinearLayout as the container, with proper equal weighting?
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".HomeScreenActivity"
tools:ignore="MergeRootFrame" >
<android.support.v4.view.ViewPager
android:id="#+id/home_screen_view_pager"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"/>
<fragment
android:id="#+id/homescreen_fragment"
android:layout_width="match_parent"
android:layout_weight="1"
android:layout_height="0dp"
class="com.krupalandharsh.touristguideexperiments.HomeScreenFragment" />
</LinearLayout>

I am confused with your xml of the homepage: "activity_homescreen".
You use relative layout for parent layout, but you also add parameter "weight" for both of two child layout, and one of it use 0dp width.
Would you like to use "weight" to allocate the space for your viewPager and fragment?
I add and change some code and show it in the following. I change the parent layout to LinearLayout and add "weightSum".
For The child layout I give 0dp for height, match_parent for width, and weight to allocate the height of them. You can chanage the parameters to fit your design.
I did not try it so I am not sure it will work. You can try it.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".HomeScreenActivity" tools:ignore="MergeRootFrame"
android:weightSum="6"
>
<android.support.v4.view.ViewPager
android:id="#+id/home_screen_view_pager"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="5"/>
<fragment
android:id="#+id/homescreen_fragment"
android:layout_width="match_parent"
