Show hide alternate LinearLayouts when selecting RadioButton in 2 RadioGroups

Six RadioButtons aligned as 3 columns and 2 rows in a RadioGroup, so 6 RB-s in RG. If user selects a RB, right under it image1 and text1 are shown and under alternated RB-s image1 and text2 are also shown. User may select any RB. The proper behavior looks like that https://photos.app.goo.gl/NEqTaxsY6daxD3kJA

Image1 is always the same, while text1 and text2 differ. Text1 'You' is shown under the selected RB and text2 'Your friend' - under alternating RB-s.
The quetion still is how to show/hide image1 and text 1 or text 2 alternatively?
I can show/hide image1 and text-s under RB-s which is in the same column, but not alternating RB-s.

Trying to save the state of a toggle Button and make visible some view depending on it

I have a switch that when you click it it populates a RecyclerView and trying to save the state through the lifecycle.
This is the xml
<Switch
android:id="#+id/reviewLabel"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="#dimen/eight_dp"
android:textColor="#android:color/white" />
This is the listener
private class ShowReviewsListener implements CompoundButton.OnCheckedChangeListener{
#Override
public void onCheckedChanged(CompoundButton compoundButton, boolean isChecked) {
if(isChecked == true){
showReviews();
isReviewButtonClicked = true;
}else if(isChecked == false){
isReviewButtonClicked = false;
}
}
}
This is what happens when you click it
public void showReviews() {
mReviewList.setHasFixedSize(true);
mReviewList.setVisibility(View.VISIBLE);
fakeView2.setVisibility(View.VISIBLE);
}
This is how i try to save it and retrieve it
#Override
protected void onSaveInstanceState(Bundle outState) {
outState.putInt(INSTANCE_MOVIE_ID, mMovieId);
outState.putBoolean(IS_IN_FAVORITES, isInFavsAlready);
outState.putBoolean(REVIEW_BUTTON, isReviewButtonClicked);
super.onSaveInstanceState(outState);
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_movie_detail);
mDb = AppDatabase.getInstance(getApplicationContext());
mToolbar = findViewById(R.id.toolbar);
mToolbar.setTitle(R.string.movie_details_title);
ButterKnife.bind(this);
if (savedInstanceState != null && savedInstanceState.containsKey(INSTANCE_MOVIE_ID)) {
mMovieId = savedInstanceState.getInt(INSTANCE_MOVIE_ID, DEFAULT_MOVIE_ID);
}
if(savedInstanceState !=null && savedInstanceState.containsKey(IS_IN_FAVORITES)){
isInFavsAlready = savedInstanceState.getBoolean(IS_IN_FAVORITES, false);
}
if(savedInstanceState !=null && savedInstanceState.containsKey(REVIEW_BUTTON)){
isReviewButtonClicked = savedInstanceState.getBoolean(REVIEW_BUTTON, false);
}
Log.d(LOG_TAG, "review button " + isReviewButtonClicked);
Intent i = getIntent();
if (i != null && i.hasExtra(EXTRA_MOVIE)) {
if (mMovieId == DEFAULT_MOVIE_ID) {
mMovieId = i.getIntExtra(EXTRA_MOVIE, DEFAULT_MOVIE_ID);
mMovie = i.getParcelableExtra(EXTRA_MOVIE);
populateUI(mMovie);
}
}
setTrailers();
setReviews();
if (isReviewButtonClicked) {
showReviews();
}
int movieID = Integer.parseInt(mMovie.getMovieId());
isMovieInFavorites(movieID);
reviewSwitch.setOnCheckedChangeListener(new ShowReviewsListener());
favoriteToggle.setOnCheckedChangeListener(new FavoriteListener());
}
Right now even though the isChecked is true, whenever i rotate the device, the views from showReviews() are staying hidden.
EDIT: Added full onCreate & image
Reviews handle
private class FetchReviewsAndTrailersTask extends AsyncTask<URL, Void, String[]> {
#Override
protected String[] doInBackground(URL... urls) {
URL searchReviewUrl = NetworkUtils.createReviewsUrl(mMovie.getMovieId());
URL searchVideoUrl = NetworkUtils.createVideosUrl(mMovie.getMovieId());
String jsonReviewString = "";
String jsonVideoString = "";
try {
jsonReviewString = NetworkUtils.makeHttpRequest(searchReviewUrl);
jsonVideoString = NetworkUtils.makeHttpRequest(searchVideoUrl);
} catch (IOException e) {
Log.e("Main Activity", "Problem making the HTTP request.", e);
}
return new String[]{jsonVideoString, jsonReviewString};
}
#Override
protected void onPostExecute(String[] jsonString) {
if (jsonString == null) {
fakeView.setVisibility(View.VISIBLE);
}
mTrailers = JsonUtils.extractTrailersFromJson(jsonString[0]);
mReviews = JsonUtils.extractReviewsFromJson(jsonString[1]);
populateReviewsAndTrailers(mReviews, mTrailers);
}
}
private void populateReviewsAndTrailers(List<Review> review, List<Trailer> trailers){
if (review.isEmpty()) {
reviewSwitch.setText(R.string.reviewLabelNone);
} else {
reviewSwitch.setText(R.string.reviewLabelExist);
fakeView.setVisibility(View.GONE);
mAdapter = new MovieReviewsRecyclerViewAdapter(MovieDetailActivity.this, mReviews);
mReviewList.addItemDecoration(new DividerItemDecoration(getApplicationContext(), DividerItemDecoration.VERTICAL));
mReviewList.setAdapter(mAdapter);
mReviewList.setVisibility(View.GONE);
}
if(trailers.isEmpty()){
trailersHeader.setText(R.string.trailersNA);
}else{
trailersHeader.setText(R.string.trailerHeader);
mTrailerAdapter = new MovieTrailersRecyclerViewAdapter(MovieDetailActivity.this, mTrailers);
mTrailersList.setAdapter(mTrailerAdapter);
}
}

I guess you forget to show reviews after rotating screen.
Try this:
if(savedInstanceState !=null && savedInstanceState.containsKey(REVIEW_BUTTON)){
isReviewButtonClicked = savedInstanceState.getBoolean(REVIEW_BUTTON, false);
if (isReviewButtonClicked) showReviews();
}

duplicate actions in android application when going to home screen

Intro:
My client require some components across the application like navigationDrawer, toolbar. So I have a MainActivity having two toolbar(top/bottom) and two navigation drawer(left/right). All other screens consist of fragments that I change in MainActivity. I have a little problem that is some of the action are being duplicated.
Cases:
In some fragments when user perform an action i.e.
1: User press "Add To Cart" button and press home button that is in toolbar Bottom, the code of "Add To Cart" button run twice (once clicking button, once going to home screen) so my item is being added to cart twice.
2: In another fragment I have "apply coupon" checkbox when user check that checkbox an AlertDialog appear and when user go to home screen the AlertDialog again appear in the home screen.
I'm simply recreating the main activity on home button press with recreate();
I check the code but can't understand why those actions duplicate. If someone faced the same or a bit similar problem please guide me how to tackle that. Any help would be appreciated.
If I need to show code tell me which part?
Edit:
inside onCreateView of fragment Cart Detail
useCoupon.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if (isChecked) {
createAndShowCustomAlertDialog();
}
}
});
Sequence of this code is Main Activity(Main Fragment)=>Product Frag=>Cart Detail Frag.

I removed global variables and some method because of length.

You should not use recreate() method here, as it forces the activity to reload everything. Just use intent to call your Home activity, that should solve this issue.

From the hint of #Akash Khatri I use to switch to mainFragment and its fine now. Actually #Akash is right recreate(); everything at present But as I was setting main fragment in OnCreate of MainActivity. So, It was hard to notice that Android first recreate everything and in no time It call the main Fragment.
I do not using Intent to start the same activity again Because Switching fragment is more convenient. And also I pass Some extras to it that I will loose With new Intent.

Filter data by input in custom ArrayAdapter displays empty items

I implemented EditText widget to filter items in ListFragment using custom ArrayAdapter.
It works fine but the filtered list contains EMPTY items as well as filtered items.
I found that i should clear the adapter before to repopulate it, right?
Could it be something like
adapter.clear();
listview.getAdapter().notifyDataSetChanged();
Anyway I cannot find working solution.
Any clue to fix this bug, please?
public class CustomListAdapter extends ArrayAdapter<UnitView> {

Android YouTubeSupportFragment player returning null

I have been working on a personal Android project related to YouTube based off a demo, however I have ran into an issue that I can't seem to figure out (or understand).
The original code uses a basic PlayerView whereas this uses a YouTubePlayerSupportFragment.
The app plays videos just fine as long as player.cueVideo("VIDEOID") is inside onInitializationSuccess. But will crash with a NullPointerException on player variable if placed inside the method playVideoAtSelection.
** The original code had the following line inside onInitializationSuccess, however for me it's telling me that player cannot be resolved. **
I've never seen this used like this before so it has been throwing me off.
this.player = player;

java.lang.NullPointerException

You are getting NullPointerException because your player variable is not initialized. You have commented this line:
this.player = player;
And for the question what is this.player = player?
this refers to the current object
For example:
public class myClass{
int x;
public myClass(int x){
this.x = x;
}
}
In the above example, you have used this because, you want to assign value of x to the x(attribute of myClass).
PS: If you are confused with this you can easily do the following:
Change your variable name to something else, may be mPlayer
and change
this.player = player to mPlayer = player;
Edited:
You have declared the YouTubePlayer outside the class. Move it inside i.e. Before overriding onCreate(..) method.
Updated:
Since the player is not attribute of the class, it won't know what it is. This is similar to not declaring any variable.
