Like the infoWindows click a specific Object,

Trenton

google map filled with markers from ArrayList<Object>, Question in the following way for the infoWindows to transmit the specific Оbject♪

public void onInfoWindowClick(Marker marker) {
        Intent route = new Intent(getActivity(), Details.class);
                            route.putExtra("route", route);
                            startActivity(route);
                        }

https://developers.google.com/android/reference/com/google/android/gms/maps/GoogleMap.html#addMarker%28com.google.android.gms.maps.model.MarkerOptions%29 returning the reference to the added value Marker♪ This reference can be retained in a separate table (type) HashMap<Marker, YourObject>and then get the object.
GoogleMap does not guarantee that the facility is in onInfoWindowClick(Marker marker) It'll be the same as the object. marker = gmap.addMarker(..)so you need to use it to compare. marker.equals (sighs) HashMap This is the case.

You must modify the attribute values android:layout_width and android:layout_height They're like wrap_content<ImageView app:srcCompat="@mipmap/ic_launcher_round" android:layout_width="wrap_content" android:layout_height="wrap_content" /> For specific sizes, example:<ImageView app:srcCompat="@mipmap/ic_launcher_round" android:layout_width="100dp" android:layout_height="100dp" />

So you can know the name of the class, I hope it serves you: echo "El nombre de la clase es: " , get_class($var) , "\n"; If you have more doubts about this it can serve you : https://www.php.net/manual/es/function.get-class.php

I think the most optimised solution is to eliminate android-support-v4.jar since his project Ionic,MyProject - plan for the future and for the future REMOVE Android-supportIf you don't find this route jar, you can search for it in plugins cordova-android-support-v4.jar.

Well, you didn't hit much, but you can do something like:let obj = { "title": "Fooz - Mayer", "description": "Lorem ipsum", "featured": false, "image": { "src": "https://placekitten.com/g/404/404", "alt": "alt for product image", "title": "product image", } }; const array = []; Object.keys(obj).forEach((k) => { if (typeof obj[k] === 'object') { const objTmp = obj[k]; Object.keys(obj[k]).forEach((k) => { array.push(${k}: ${objTmp[k]}) }); } else { array.push(${k}: ${obj[k]}); } }); console.log(array);Let's look at the object and if one of its key values is another object we go back and save each item from that object to the array you want to save.

if Product - it's cool. No. ? He is. nullableI mean, it could be important. null♪I mean, the original code will work perfectly:private Product _product; public Product Product //The type 'Product' must be a non-nullable value type in order to use it as parameter 'T' in the generic type or method 'Nullable<T>' { get { if (_productId == 0) return null; if (_product == null) { _product = ProductsCollection.Instance[_productId]; } return _product; } }

To change the color of the hamburger icon you should open the file style. xmlAnd then in this class, add the line responsible for the color:<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar"> <item name="windowNoTitle">true</item> <item name="windowActionBar">false</item> <item name="colorPrimary">@color/colorPrimary</item> <item name="colorPrimaryDark">@color/colorPrimaryDark</item> <item name="colorAccent">@color/colorAccent</item> /*linha responsável pela cor abaixo*/ <item name="drawerArrowStyle">@style/DrawerArrowStyle</item> /*linha responsável pela cor acima*/ </style> <style name="DrawerArrowStyle" parent="@style/Widget.AppCompat.DrawerArrowToggle"> <item name="spinBars">true</item> <item name="color">@android:color/black</item> </style> Then just change the color in the line <item name="color">@android:color/black</item> Responding to Woton Sampaio:The scheme is the same, but to change the color of the 3 pointed, you should add the following line:<item name="android:textColorSecondary">@color/white</item> Any questions with the implementation let us know.Hugs

Use ViewPager for swaps between fragments. You'll be glad to see him in the adapter! I'll bring the code for the basic solution below.Create a laiate from the viewpager:<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"> <android.support.v4.view.ViewPager android:id="@+id/vpPager" android:layout_width="match_parent" android:layout_height="wrap_content"> </android.support.v4.view.ViewPager> </LinearLayout> Then we create a few fragments that will be in our viewpager. The next step will be to create an adapter and assign it to our viewpager:public static class MyPagerAdapter extends FragmentPagerAdapter { private static int NUM_ITEMS = 3; public MyPagerAdapter(FragmentManager fragmentManager) { super(fragmentManager); } // Возвращает общее количество фрагментов @Override public int getCount() { return NUM_ITEMS; } // Возвращает фрамгент, который будет отображаться сейчас @Override public Fragment getItem(int position) { switch (position) { case 0: // Fragment # 0 - This will show FirstFragment return FirstFragment.newInstance(0, "Page # 1"); case 1: // Fragment # 0 - This will show FirstFragment different title return FirstFragment.newInstance(1, "Page # 2"); case 2: // Fragment # 1 - This will show SecondFragment return SecondFragment.newInstance(2, "Page # 3"); default: return null; } } // Возвращает заголовок (например, если используете TabLayout) @Override public CharSequence getPageTitle(int position) { return "Page " + position; } } And after that, our adapter is assigned to our viewpager in the activate code:... ViewPager vpPager = (ViewPager) findViewById(R.id.vpPager); adapterViewPager = new MyPagerAdapter(getSupportFragmentManager()); vpPager.setAdapter(adapterViewPager); ...

First I recommend replacing RelativeLayout with FrameLayout and adding the button you want. To get the operation you are looking for, you must make it visible when you get new data and make it invisible when the user clicks.<?xml version="1.0" encoding="utf-8"?> <FrameLayout 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:id="@+id/activity_show_images" android:layout_width="match_parent" android:layout_height="match_parent" android:background="#454545" tools:context=".Activity"> <androidx.recyclerview.widget.RecyclerView android:id="@+id/recyclerview" android:layout_width="match_parent" android:layout_height="match_parent" > </androidx.recyclerview.widget.RecyclerView> <Button android:id="@+id/button_see_new" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center_horizontal" android:layout_marginTop="10dp" android:visibility="gone"/> </FrameLayout> The Activity Code would remain that wayAdView mAdView; Button seeNew; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_mostrarmemes); //Ocultar ActionBar getSupportActionBar().hide(); seeNew=findViewById(R.id.button_see_new); seeNew.setOnClickListener(this); recyclerView = findViewById(R.id.recyclerview); recyclerView.setHasFixedSize(true); recyclerView.setLayoutManager(new LinearLayoutManager(this)); progressDialog = new ProgressDialog(this); subidas = new ArrayList<>(); adapter = new Myadaptador(this,subidas); ///////////////////////////////////////Hoy recyclerView.setAdapter(adapter); ///////////////////////////////////////Hoy //Mostrar Progress Dialog mientras fetching images progressDialog.setMessage("Espera..."); progressDialog.show(); mDatabase = FirebaseDatabase.getInstance().getReference(Constantes.DATABASE_PATH_UPLOADS); //adding an event listener to fetch values mDatabase.addValueEventListener(new ValueEventListener() { @Override public void onDataChange(DataSnapshot snapshot) { //dismissing the progress dialog progressDialog.dismiss(); //iterating through all the values in database for (DataSnapshot postSnapshot : snapshot.getChildren()) { Upload upload = postSnapshot.getValue(Upload.class); // Hacer que las imagenes nuevas se vean primero subidas.add(0,upload); } adapter.notifyItemRangeInserted(0, (int) snapshot.getChildrenCount()); //Si la lista carga por primera vez, no es necesario mostrar el botón if(subidas.size()!=snapshot.getChildrenCount()){//Sólo muestra el botón si la lista ya tenía datos y sólo se agregaron más seeNew.setVisibility(View.VISIBLE); } } @Override public void onCancelled(DatabaseError databaseError) { progressDialog.dismiss(); } }); } public void onClick(View v){ if(v.getId()==R.id.button_see_new){ //Recorre el recyclerView recyclerView.smoothScrollToPosition(0); //Vuelve a ocultar el botón seeNew.setVisibility(View.GONE); } }

Asset pictures should lie in the asset folder, not in the folder drawable. In doing so, the folder should be created by a studio, not manually at the DS level. Try this: assetManager = getResources().getAssets(); InputStream stream; try { String someimage = ImageName.substring(0,15); stream = assetManager.open("image.jpg"); Drawable flag = Drawable.createFromStream(stream, someimage); imageView.setImageDrawable(flag); } As another option, it's the use of the outside library, for example, http://square.github.io/picasso/ ♪

You are trying to save text (coded string) in a binary file (wb). writer.writerow waits for a text string (which is what you pass) not bytes, simply opens the writing file in text mode ('w' instead of 'wb'(c):import csv with open("Libro.csv", "r", encoding="utf8") as csvfile: with open("results.csv", 'w', encoding="utf8") as csv_out: reader = csv.DictReader(csvfile, dialect='unix', delimiter = ",") writer = csv.writer(csv_out, dialect='unix', delimiter=",", quotechar='"', quoting=csv.QUOTE_MINIMAL) writer.writerow(["texto"]) for row in reader: writer.writerow([row["texto"]]) Edition:If you want to use the list as you do in your code, it's enough that you're about it:for item in sent: writer.writerow([item]) Or use writer.writerows and a generator:import csv with open("Libro.csv", "r", encoding="utf8") as csvfile: reader = csv.DictReader(csvfile, dialect='unix', delimiter = ",") sent =[] for row in reader: sent.append(row["texto"]) with open("results.csv", 'w') as csvfile: writer = csv.writer(csvfile, dialect='unix', delimiter=",", quotechar='"', quoting=csv.QUOTE_MINIMAL) writer.writerow(['texto']) writer.writerows([row] for row in sent)

The code does not show where the variable counterView refers to the component that should display the text. The simplest option for you will be to make a variable or a publicly accessible one.public Text counterView; or visible to the Inspector[SerializeField] Text counterView; and then in the Inspector, ask the variable meaning by moving the necessary text.

Example:class SomeClass { public: SomeClass() { a = 5; } SomeClass(int l_a) { a = l_a; } SomeClass& operator=(const SomeClass &l_copy) { this->a = l_copy.a; return *this; } int a; }; SomeClass a;SomeClass b;a=b equals the following: a.operator=(b);All that's happening in this operator is this-statea=l_copy.a and everything.Return *this is ignored. Not ignored, for example, when SomeClass &ref=(a=b) and in some other cases; (1)return *this is the return of a new copy of the facility, i.e. updated a;(2) SomeClass &refA= *this, i.e. a;(3) The reference is made to the reference of SomeClass &refB=refA;SomeClass &ref = a does not cause the transfer operator because we simply record this object at this address.

WinRAR's not gonna open the app. WinRAR's can open a apk and get resources out. Reversely, they should be packed in such a way that the signature certificate is not the same.
It does not have its own functions like nothrow, but by specifying it, it generally says an object to change behavior to another operator or class.
