Activity is hidden by fragment, it is not useable

Activity is hidden by fragment, it is not useable - java

i have builded an app that works perfectly on android with api higer than 21. The problem is that this instruction of my code:
mFragmentTransaction.replace(R.id.content_frame, new TabFragment()).commit();
Works in different way on API less then 21.
On Api less then 21 the new fragment hide the previus activity, so that i can't click on my Floating Action Button.
Here are two images that explain in abetter way my problem.
API HIGER THAN 21
API LESS THAN 21
So my question is: How can i have the same result in API less then 21 that i have on API Higer then 21?
Here is the affected part of the Main Activity Code:
public class MainActivity extends AppCompatActivity {
public static AppDataBase appDataBase;
public static UserDataBase userDataBase;
static FragmentManager mFragmentManager;
static FragmentTransaction mFragmentTransaction;
private DrawerLayout myDrawerLayout;
final String TXT_MAINACTVT_USER_HAVE_NOT_ADDED_CONSOLE = "Add a console!";
TextView currentConsole;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
appDataBase = new AppDataBase(this);
userDataBase = new UserDataBase(this);
myDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
currentConsole = (TextView) findViewById(R.id.txt_Mainactvt_currentConsole);
currentConsole.setText(TXT_MAINACTVT_USER_HAVE_NOT_ADDED_CONSOLE);
tabLayoutManagement();
floatingActionButtonManagement();
leftDrawerMenuManagement();
rigthDrawerMenuManagement();
populateMyConsole();
}
void tabLayoutManagement() {
mFragmentManager = getSupportFragmentManager();
mFragmentTransaction = mFragmentManager.beginTransaction();
mFragmentTransaction.replace(R.id.content_frame, new TabFragment()).commit();
}
// Floating Action Button
private void floatingActionButtonManagement() {
FloatingActionButton fab_addGame = (FloatingActionButton)findViewById(R.id.fab_AddGame);
fab_addGame.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
/*
The currentConsole TextView is used to show at the user wich console is selected.
We use it to have a strng that conteins the selected console.
Call the method that manage the click event of the FloatingActionButton. We pass the console name.
*/
String currentConsoleName = currentConsole.getText().toString();
floatingActionButtonClickEvent(currentConsoleName);
}
});
}
private void floatingActionButtonClickEvent(String currentConsoleName) {
/*
Check if user have added a console. If he did start a menu for adding games, else start an
error message
*/
if (!currentConsoleName.equals(TXT_MAINACTVT_USER_HAVE_NOT_ADDED_CONSOLE)) {
popUpViewAddGameBuild(currentConsoleName);
}
else
mySimpleAlertDialogMethod("Attention!", "Before you enter game, you must enter a console.", true, true);
}
private void popUpViewAddGameBuild(String currentConsoleName) {
/*
Build the view that show the menu for adding games.
*/
LayoutInflater inflater = this.getLayoutInflater();
View popupView = inflater.inflate(R.layout.popupview_addgame, null);
PopupWindow popupWindow = new PopupWindow(
popupView,
WindowManager.LayoutParams.MATCH_PARENT,
WindowManager.LayoutParams.MATCH_PARENT);
popupWindow.setInputMethodMode(PopupWindow.INPUT_METHOD_NEEDED);
popupWindow.setFocusable(true);
popupWindow.showAtLocation(popupView, 0, 0, 0);
}
Here is the TabLayout Class:
public class TabFragment extends Fragment {
public static TabLayout tabLayout;
public static ViewPager viewPager;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View x = inflater.inflate(R.layout.tab_layout, null);
tabLayout = (TabLayout) x.findViewById(R.id.tabs);
viewPager = (ViewPager) x.findViewById(R.id.viewpager);
viewPager.setAdapter(new MyAdapter(getChildFragmentManager()));
tabLayout.post(new Runnable() {
#Override
public void run() {
tabLayout.setupWithViewPager(viewPager);
}
});
return x;
}
public class MyAdapter extends FragmentPagerAdapter {
public int position;
public MyAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int position) {
switch (position){
case 0 :
return new DesireFragment();
case 1 :
return new BuyedFragment();
case 2 :
return new StartedFragment();
case 3 :
return new FinishedFragment();
case 4 :
return new AllTrophiesFragment();
}
return null;
}
#Override
public int getCount() {
return 5;
}
#Override
public CharSequence getPageTitle(int position) {
switch (position){
case 0 :
return "Desire";
case 1 :
return "Buyed";
case 2 :
return "Started";
case 3 :
return "Finished";
case 4 :
return "AllTrophies";
}
return null;
}
}
}
There is the layout of the MainActivity:

You replace the content of your FrameLayout with an Fragment. this leads to your strange result.
Add a Layout to your Framelayout instead and use it as your FragmentContainer:
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
app:backgroundTint="#color/colorPrimary"
app:borderWidth="0dp">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/content_frame"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="30dp"
android:textAppearance="?android:attr/textAppearanceLarge"
android:id="#+id/txt_Mainactvt_currentConsole"
android:layout_gravity="center_horizontal|top"
android:layout_marginTop="50dp"/>
<android.support.design.widget.FloatingActionButton
android:id="#+id/fab_AddGame"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="17dp"
android:layout_marginRight="17dp"
android:src="#drawable/ic_mode_edit_white_24dp"
android:layout_gravity="bottom|right"
android:background="#color/colorPrimary" />
</FrameLayout>

Try to place your FrameLayout with this button to the end of layout

Can the RecyclerView scroll with the rest of the fragment layouts?

I have set up a RecyclerView adapter with ViewPager in an activity namely TvShowEpisodeDetails , it works well but there is one issue, the Layout of RecyclerView is fixed while scrolling up and down in the Fragment(TvShowEpisodeDetailsFragment). But I want it to scroll with them.
The RecyclerView and ViewPager are both set inside viewpager_with_toolbar_overlay.xml Layout , and both has been settup in The Activity.
TvShowEpisodeDetailsFragment is the fragment class which belongs to activity class TvShowEpisodeDetails , the fragment creates as many episodes as a TV Show season can offer.
And off course this issue will be gone if I set RecyclerView adapter inside fragment, but I will get non-fixable highlighting and scrolling issues , that is why I set it inside the activity because it does not give those issues.
I need to make it work somehow inside the activity.
My goal is that RecyclerView and ViewPager has to be in the same layout XML file and they both must either be in the activity or fragment class
Is it possible to make the RecyclerView scroll with rest of the fragment layouts?
or
Is it possible to do it programmatically?
Here is the activity
public class TvShowEpisodeDetails extends MizActivity{
#Override
protected int getLayoutResource() {
return R.layout.viewpager_with_toolbar_overlay;
}
#Override
public void onCreate(Bundle savedInstanceState) {
mBus = MizuuApplication.getBus();
super.onCreate(savedInstanceState);
// Set theme
setTheme(R.style.Mizuu_Theme_NoBackground);
// setting episodeslist
final ArrayList<PlanetModel> episodeslist = new ArrayList<>();
for(TvShowEpisode e : mEpisodes){
episodeslist.add(new PlanetModel(e.mEpisode));
}
// setting RecyclerView
mEpisodesList = (RecyclerView) findViewById(R.id.episodesLIST);
// Setting LinearLayoutManager
LinearLayoutManager layoutManager
= new LinearLayoutManager(this.getApplicationContext(), LinearLayoutManager.HORIZONTAL, false);
//mEpisodesList.setLayoutManager(new LinearLayoutManager(mContext));
mEpisodesList.setLayoutManager(layoutManager);
// Setting RecyclerView Adapter
PlanetAdapter.OnItemClickListener indicatorCallback = new PlanetAdapter.OnItemClickListener() {
#Override
public void onItemClick(String item) {
SharedPreferences getPref = getContext().getSharedPreferences("PlanetAdapter", Context.MODE_PRIVATE);
int pos = getPref.getInt("newPosition", 0);
mViewPager.setCurrentItem(pos,false);
}
};
final PlanetAdapter planetAdapter = new PlanetAdapter(episodeslist,indicatorCallback);
mEpisodesList.setAdapter(planetAdapter);
// Setting ViewPager
mViewPager = (ViewPager) findViewById(R.id.awesomepager);
mViewPager.setAdapter(new TvShowEpisodeDetailsAdapter(getSupportFragmentManager()));
mViewPager.setOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener() {
#Override
public void onPageSelected(int position) {
planetAdapter.setSelectedIndex(position);
planetAdapter.notifyDataSetChanged();
mEpisodesList.smoothScrollToPosition(position);
//mEpisodesList.scrollToPosition(position);
for (int i=0; i<episodeslist.size(); i++)
{
episodeslist.get(i).setPlanetSelected(false);
}
episodeslist.get(position).setPlanetSelected(true);
ViewUtils.updateToolbarBackground(TvShowEpisodeDetails.this, mToolbar, 0, mEpisodes.get(position).getTitle(), Color.TRANSPARENT);
}
});
if (savedInstanceState != null) {
mViewPager.setCurrentItem(savedInstanceState.getInt("tab", 0));
} else {
for (int i = 0; i < mEpisodes.size(); i++) {
if (mEpisodes.get(i).getSeason().equals(MizLib.addIndexZero(mSeason)) && mEpisodes.get(i).getEpisode().equals(MizLib.addIndexZero(mEpisode))) {
mViewPager.setCurrentItem(i);
break;
}
}
}
}

I have set up a RecyclerView adapter with ViewPager in an activity namely TvShowEpisodeDetails , it works well but there is one issue, the Layout of RecyclerView is fixed while scrolling up and down in the Fragment(TvShowEpisodeDetailsFragment). But I want it to scroll with them.
It's hard to use the RecyclerView outside of the ViewPager page fragment; because you can't synchronize and link the touch/motion events when you scroll the page up/down (or when you swipe to next/previous page) between both the page fragment and a standalone (i.e. activity) RecyclerView. Even that won't be smooth.
So, the RecyclerView should be a part of the ViewPager page.
And off course this issue will be gone if I set RecyclerView adapter inside fragment, but I will get unfixable highlighting and scrolling issues
So, now the issue of adding the RecyclerView in the ViewPager fragment is the highlighting issue of the RecyclerView item when you click on any item or when you swipe the ViewPager to right/left page.
But, the main issue is that there is a RecyclerView instance per page, i.e. if you have 5 pages, then you have 5 RecyclerViews.
So, it's a cumbersome to track highlighting only within the RecyclerView adapter class. And hence manipulating that with OnClickListeners solely will have issues of linking these RecyclerView and adapter instances together to update their highlighting item.
So, a simpler approach is to pass a parameter to the RecyclerView adapter with the selected item (which is definitely equals to the current ViewPager page position).
And then do a check in the onBindViewHolder() if the position equals to the passed-in value, then highlight the item; otherwise keep items with the original color.
So, wrapping this up into actions:
Change the adapter constructor to accept a highlighted_position parameter
public PlanetAdapter(ArrayList<PlanetModel> episodeslist,
int highlightedPosition, OnItemClickListener listener)
Whenever you create the ViewPager fragment using newInstance() pass-in the current position of the page fragment:
So, in the TvShowEpisodeDetails activity:
for (int i = 0; i < mEpisodes.size(); i++)
fragments.add(TvShowEpisodeDetailsFragment
.newInstance(mShowId,
Integer.parseInt(mEpisodes.get(i).getSeason()),
Integer.parseInt(mEpisodes.get(i).getEpisode()),
i)); // The position
And in the TvShowEpisodeDetailsFragment fragment, register this into a field in the fragment argument:
public static TvShowEpisodeDetailsFragment newInstance(String showId, int season, int episode, int position) { // adding position
TvShowEpisodeDetailsFragment pageFragment = new TvShowEpisodeDetailsFragment();
Bundle bundle = new Bundle();
// trimmed code.
bundle.putInt("position", position); // <<<< into the bundle
pageFragment.setArguments(bundle);
return pageFragment;
}
And set that in the adapter creation:
int currentPosition = getArguments().getInt("position");
planetAdapter = new PlanetAdapter(episodeslist, currentPosition, new PlanetAdapter.OnItemClickListener() {
#Override
public void onItemClick(final int pos) {
mCallback.sendText(pos);
}
});
And reflect that in the adapter to highlight the item:
public class PlanetAdapter extends RecyclerView.Adapter<PlanetAdapter.PlanetViewHolder> {
private final int highlightedPos;
public PlanetAdapter(ArrayList<PlanetModel> episodeslist, int highlightedPosition, OnItemClickListener listener) {
this.episodeslist = episodeslist;
this.listener = listener;
this.highlightedPos = highlightedPosition; // <<< set the position
}
#Override
public void onBindViewHolder(PlanetAdapter.PlanetViewHolder vh, final int position) {
TextView tv = (TextView) vh.itemView;
PlanetModel planetModel = episodeslist.get(position);
tv.setText(planetModel.getPlanetName());
tv.setCompoundDrawablesWithIntrinsicBounds(R.drawable.bg, 0, 0, 0);
if (highlightedPos == position) { //<<<<< Highlight the item
vh.itemView.setBackgroundColor(getContext().getResources().getColor(R.color.colorPrimaryLight));
Log.d("LOG_TAG", "onClick: Highlight item: " + highlightedPos);
} else {
vh.itemView.setBackgroundColor(getContext().getResources().getColor(R.color.colorPrimaryDark));
Log.d("LOG_TAG", "onClick: No highlight: " + highlightedPos);
}
}
}

Make the layout below button

In one of my fragment class, it has two buttons (A and B) on top, used to switch to another fragment when clicked using viewPager.
When buttonA is clicked, it should switch to page A and so on.
When I click button A, how can I make the text in A show below the two buttons?
fragment_menu.xml
<?xml version="1.0" encoding="utf-8"?>

viewPager.setAdapter(new ViewPagerAdapter(getActivity().getFragmentManager()));
Button btnA = (Button) v.findViewById(R.id.buttonA);
Button btnB = (Button) v.findViewById(R.id.buttonB);
btnA.setOnClickListener(new View.OnClickListener() {
#Override

}
});
btnB.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {

}
});
return v;
}
}

Output

try with below code.hope it is helpful for you ;)
P.S. You just need to set button style as you want :)
<RelativeLayout

android:layout_height="match_parent" />
<LinearLayout
android:id="#+id/llButton"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:layout_alignParentBottom="true"
android:layout_marginBottom="10dp">
<Button
android:id="#+id/buttonA"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:padding="15dp"
android:text="ButtonA"
android:textSize="12sp" />
<Button
android:id="#+id/buttonB"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="15dp"
android:layout_marginTop="10dp"
android:layout_marginRight="15dp"
android:backgroundTint="#color/colorAccent"
android:padding="15dp"
android:text="ButtonB"
android:textSize="12sp" />
</LinearLayout>
</RelativeLayout>

Since you are using Relative Layout you can add layout_below
<androidx.viewpager.widget.ViewPager
android:layout_below="#id/buttonB"
android:id="#+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent" />

you are doing it wrong, You cannot align a button to itself. That's why your buttons are not working properly. In your button B do this:
android:layout_toRightOf="#+id/buttonA"
instead of this:
android:layout_toRightOf="#+id/buttonB"
And to your viewPager add "android:layout_below:"
<androidx.viewpager.widget.ViewPager
android:id="#+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/buttonA" />

You have to set your layout like this....
[I think you want something like this 2 button fisrt and then viewpager for change the content ][1]

Issues with Android Soft Keyboard and panAdjust

I am trying to achieve similar effect to the one found in Todoits application where you can click on FAB and it shows a floating popup for adding new task.
This is how it looks:
The closest to it I managed to achieve is this:
It is nearly there, but I want the popup to be about 10dp above the keyboard and scroll the recycle viewer to the last item but I can't get it there :/ Currently, the popup is centred.
I have tried before adding the popup to the bottom of the screen and setting android:windowSoftInputMode="adjustResize" but this was moving my bottom navigation above the keyboard too. Setting windowsSoftInputMode to panAdjust was cutting away the toolbar and few items from the list.
Have you got any suggestions about how to achieve similar effect to the one in Todoist? Maybe with a DialogFragment?

Why am I getting the error: java.lang.RuntimeException: java.lang.IllegalStateException: RecyclerView has no LayoutManager on (HelpActivity.java:28)

I'm unable to figure out what the problem is.
Please let me know.
Thanks in advance.

You cannot put your child elements directly inside the recycler view.
You need to create separate row layout like the one you create in listview.
Just remove the xml code written inside recycler view and insert it inside row_layout xml file and then inflate that row layout file inside your adapter instead.
<RelativeLayout

android:layout_height="wrap_content"

<TextView

</RelativeLayout>
Just create separate file for row_layout containing above content and inflate it like below inside your oncreateviewholder:
View v = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.**<new_layout_you_will_create>**, viewGroup, false);

I just made a small change in your content_help.xml and it works fine for me..

<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/option"
android:layout_toRightOf="#+id/optionIcon"
android:layout_alignParentTop="true"
android:textSize="30sp"

<TextView

android:layout_height="wrap_content"
android:id="#+id/subOption"
android:layout_toRightOf="#+id/optionIcon"
android:layout_below="#+id/option"
/>
If you are using the recyclerview in activity_help.xml, no need to use the same for your row-content.
Hope this will solve your problem

Can't get Admob to show on multiple layouts?

I am trying to get Admob to display on my layout_one.xml and layout_two and can't get it to show. This app has a lot of swipe left and right and I want to display one ad over both layouts
Here are all my xml layouts:
activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.view.ViewPager
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/pager">
</android.support.v4.view.ViewPager>
layout_one.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:ads="http://schemas.android.com/apk/res-auto"
android:id="#+id/relative_one"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#000000"
android:focusable="true"
android:focusableInTouchMode="true"
android:orientation="vertical">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Copy"
android:id="#+id/Copy"
android:layout_centerVertical="true"
android:layout_centerHorizontal="true"
android:layout_alignParentEnd="false"
android:layout_alignParentStart="false"
android:textSize="30sp"
android:onClick="onClickCopy"/>
<EditText
android:layout_width="300dp"
android:layout_height="50dp"
android:id="#+id/stringCopy"
android:layout_above="#+id/Copy"
android:layout_centerHorizontal="true"
android:layout_marginBottom="70dp"
android:textSize="30sp"
android:inputType="text"
android:gravity="left|top"
android:background="#ffffff" />
<com.google.android.gms.ads.AdView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_alignParentBottom="true"
ads:adSize="BANNER"
ads:adUnitId="#string/banner_ad_unit_id"/>
layout_two.xml
<?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/relative_one"
android:background="#000000"
android:focusable="true"
android:focusableInTouchMode="true"
android:orientation="vertical">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Paste"
android:id="#+id/Paste"
android:layout_centerVertical="true"
android:layout_centerHorizontal="true"
android:layout_alignParentEnd="false"
android:layout_alignParentStart="false"
android:textSize="30sp"
android:onClick="onClickPaste"/>
<EditText
android:layout_width="300dp"
android:layout_height="50dp"
android:id="#+id/stringCopy"
android:layout_marginBottom="71dp"
android:textSize="30sp"
android:inputType="text"
android:gravity="left|top"
android:background="#ffffff"
android:layout_above="#+id/Paste"
android:layout_centerHorizontal="true" />
<!-- SHOULD I PUT ANOTHER ADVIEW IN THIS XML -->
</RelativeLayout>
Here is all my java classes:
MainActivity.java
public class MainActivity extends FragmentActivity {
//View Pager
ViewPager viewpager;
//AdView
AdView adView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
viewpager = (ViewPager)findViewById(R.id.pager);
PagerAdapter pAdapter = new PagerAdapter(getSupportFragmentManager());
viewpager.setAdapter(pAdapter);
}
public void onClickCopy(View v)
{
//Copy Text From layout_one to Clipboard
}
public void onClickPaste(View v)
{
//Paste Text From Clipboard
}
}
PagerAdapter.java
public class PagerAdapter extends FragmentPagerAdapter {
public PagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int arg0) {
switch (arg0) {
case 0:
return new FragmentOne();
case 1:
return new FragmentTwo();
default:
break;
}
return null;
}
#Override
public int getCount() {
return 2;
}
}
FragmentOne.java
public class FragmentOne extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
return inflater.inflate(R.layout.layout_one, container, false);
}
}
FragmentTwo.java
public class FragmentTwo extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
return inflater.inflate(R.layout.layout_two, container, false);
}
}
Where would I put this code so that when they swipe between layout_one and layout_two that the same ad will be displayed and not make a new ad request every time they change views?
//Display test Ads
adView = new AdView(this);
AdRequest request = new AdRequest.Builder()
.addTestDevice("DEVICE_ID").build();
adView.loadAd(request);

The standard pattern for doing this is to put your AdView either above or below your ViewPager and keep it static. That way you are not constantly requesting ads that you never get time to display.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
>
<android.support.v4.view.ViewPager
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:id="#+id/pager">
</android.support.v4.view.ViewPager>
<com.google.android.gms.ads.AdView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="0"
android:adUnitId="yourAdUnitId"
android:id="#+id/adView">
</LinearLayout>
This way your Adview is outside your ViewPager and remains constant across all pages.

I use the following code to cache Admob in scroll Grid View:
public View getView(int position, View convertView, ViewGroup parent) {
if (position != adNum) {
...
} else {
if (mAdView == null) {
frameLayout = new FrameLayout(mContext);
mAdView = new AdView(mContext);
...
frameLayout.addView(mAdView);
} else {
frameLayout.removeView(mAdView);
frameLayout = new FrameLayout(mContext);
frameLayout.addView(mAdView);
}
return frameLayout;
}
}
