android - Retrofit: Parse JSON with different array elements -


i using tmdb api fetch search results of movies, tvs, , people. , in results array, json objects of different type. movie, object format different tv object format. in retrofit, cant this

list<pojoclass> results;

so question how can deal these situations, json array contains different entries in retrofit.

here's json format getting tmdb api.

{ "results": [ {     "vote_average": 7.4,     "vote_count": 2301,     "id": 315635,     "video": false,     "media_type": "movie",     "title": "spider-man: homecoming",     "popularity": 86.295351,     "poster_path": "/c24sv2wethpsmda7jemn0m2p3rt.jpg",     "original_language": "en",     "original_title": "spider-man: homecoming",     "genre_ids": [         28,         12,         878     ],     "backdrop_path": "/vc8bcgjdvp0ubmnlzhnhslrbbwq.jpg",     "adult": false,     "overview": "following events of captain america: civil war, peter parker, of mentor tony stark, tries balance life ordinary high school student in queens, new york city, fighting crime superhero alter ego spider-man new threat, vulture, emerges.",     "release_date": "2017-07-05" }, {     "original_name": "spider!",     "id": 1156,     "media_type": "tv",     "name": "spider!",     "vote_count": 1,     "vote_average": 10,     "poster_path": null,     "first_air_date": "1991-09-26",     "popularity": 1.063406,     "genre_ids": [],     "original_language": "en",     "backdrop_path": null,     "overview": "spider! musical children's television series made hibbert ralph entertainment bbc aired in 1991. followed adventures of spider, protagonist, , young boy. stories told through song, performed jeff stevenson children, casey , holly, singing backing vocals. style of music varies rock 'n' roll haunting , melancholic, , produced rick cassman. bbc video entitled \"spider! - i'm scary 'cos i'm hairy!\" contained 13 episodes released after series ended. dvd version released later.",     "origin_country": [         "gb"     ] }    ]

using gson:

assuming every element in array has "media_type" field, can leverage implement own jsondeserializer.

here's template of deserialize() method should started:

@override public movietvsuperclass deserialize(jsonelement json, type typeoft, jsondeserializationcontext context) throws jsonparseexception {     jsonobject jsonobject = json.getasjsonobject();      if (!jsonobject.has("media_type")) {         // return null, throw exception, etc     }      string typekey = jsonobject.getasjsonprimitive("media_type").getasstring();      if (typekey.equals("movie")) {         return context.deserialize(jsonobject, movie.class);     }     else if (...) {         // ...     } }

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...

python Tkinter Capturing keyboard events save as one single string -

is possible store keyboard events 1 string? code below stores 1 char , prints it. card reader or bar code reader, contains collection of character/ string not 1 character @ time. goal save char pressed text variable. from tkinter import * root = tk() def key(event): text= event.char text+= event.char print ("pressed", text) def callback(event): frame.focus_set() print ("clicked at", event.x, event.y) frame = frame(root, width=100, height=100) frame.bind("<key>", key) frame.bind("<button-1>", callback) frame.pack() root.mainloop() currently, creating text variable , everytime key() function gets called, , text stores last character typed. you can define text module level variable , , use module level text inside key function - text = '' def key(event): global text text+= event.char print("pressed", text)

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
